Make: Live – Social Status Tracker

what do you want I just need a TI launch pad can't you see I'm busy here go to to find thousands of boards and stock already for immediate shipment you hey everyone welcome to make live for September my name is Tyler Wong gardener I'm the video producer here with make magazine and today I'm joined with Mike sandy see hi everyone Mike's NAC and the other person being shown that we're joined with today is the author of the project we're building today we're building Becky Stern's social status tracker and on the other end of a video call is Becky Stern nice to be here thanks for writing me and building my project yes it is a really cool project what why don't you tell us a little bit about it okay sure so I have been one that I built here it's it's a simple like shadow box display with some seven segment displays inside it and an esp8266 board that's just using a bunch of API libraries to grab my follower account from all the different social sites that matter to me I also have a separate YouTube one that was like that inspired the project to begin with hook because it looks like the YouTube play button that you get when you get a certain number of subscribers and I wanted mine to be an active counter and then I thought it would just be nice to put all the rest of the networks that I care about into a different display so it's just like a shadow box that I got on Amazon and the displays press right up against the sheet of paper I printed out with the logos on it so that it gives it a clean look right because you've done a lot of experimentation with like diffusion of LED and other lit displays we're going to be a little bit more raw here I'm going to be just doing the these bare 7-segment displays I'm also going a little bit bigger than your original one we're actually going to be displaying this in digitized booth at Maker Faire in New York next week so I want to go a little bit bigger and then do actual components if it's gonna be a did you keep those right true yeah and otherwise we're just gonna be mounting it to foam core and we'll put it in a frame too and this is actually going to be combining this current project with a previous version of it because well we're doing this for all of digit keys social things but they aren't really involved on Instructables so we want to bring in their Youtube subscriber count so we're kind of combining the two different projects together and the reason why we're doing all this this in the in the spirit of digi-key and because they are the people who actually make this entire show possible if you're not familiar with who ditch key is there an electronics distributor based here in the US and they will sell you every single component that you need to build this project or whatever project you're working on whether that's single board computers or you know microcontrollers like this guy that we're building this here this is the the note MCU ESP a teach us be eighty to sixty-six board all the way down to resistors capacitors whatever you need to build your project whether you need it for through-hole surface mount they'll they'll sell it to you they will ship to you quick sometimes I've even ordered stuff in the afternoon and it shows up on my on my desk the next morning which I don't understand how that happens that seems like witchcraft but but they they make it happen and they make this show possible and so for that we're super happy to be working with them but in the meantime we've got a project to build I've got a project to build so I'm gonna get going with building it the very first thing I need to do I should pull up my camera so you can see what I'm gonna be working on here Tyler while you're pulling that up I'm going to throw a note out there that if you guys are watching you have questions you have comments we are streaming this both on our Facebook channel and on our YouTube channel I'm trying to keep my eye on that over here so I will try to facilitate getting your questions answered please try to keep them on topic but you know what happy to have conversations yes so take a look here what I'm looking at so this is the back of these large-ish 7-segment displays well that's the front of it and the back if you look I'm looking right here you get a little bit closer pickup picture there once I start soldering are these three addressable pads so I have six of these displays here and they all run on the the I squared C you know serial bus interface so I need to give a different address to each and every single one of them so that the microcontroller knows which board to send or which display to send which numbers to so that's the very first thing I need to do so I'm going to fire up my soldering iron here I just need to add a little you just need to bridge one of those solder pads and I've made some remark here as to which one is which and I hope I kept my notes straight this display if I trust the packaging is red so I marked it with a red dot and that's a number two of course we have number one here and then we'll match all this stuff up in the code when we get into that a little bit later on but in the meantime our soldering iron is merely warm enough so we're gonna get started doing that it's really cool that the iSport c displays can all be daisy chained together because they only use two pins on your microcontroller so you're working with something like the note MCU that doesn't have a ton of space on it it's pretty compact board you don't want to have like a bunch of different solder connections clogging it up these just like daisy team to each other and then you address them and if you do make a mistake tyler you can change the address in the code accordingly so that as long as two displays don't have the same address you're all set i've been playing around with I squared C for a little bit now but I think this is actually my first time of running multiple things on the same you know having multiple devices well actually I've had multiple disparate devices but never like multiple of the same kind of display so this will be this will be new things for me I'm excited um okay I've brought along my cheat sheet here and okay so we're gonna call the red one and this is red number one and actually don't need to solder anything to this one because this is going to be our our high or low digit display and I think this is red so we're gonna make that to be for YouTube but on red 2 which will be our high digits display I need to short a zero so that's this one that's this solder pad right there and here's my solder and yeah I cannot stress that enough you have any questions for for myself for Becky about how this project works or anything else about this project pop those into the chat and we will we will answer them for you you know what I'm great I'm surprised about is the the size of these the seven digit display here is this looks larger than the one that you posted in your in your videos for these is that is that correct yeah Tyler's going super-sized I mean my I didn't point blank seven frame and I'm using the point five six digit high quick by six-inch digit height okay and he's using like that one point two or larger right that the giant the biggest ones yeah well I didn't quite go with the spark fund makes like saying it's single digit seven segment displays that are like 6.5 inches tall I didn't quite go that big I didn't want to like do that high school football scoreboard but we could do that real quick I think you gotta switch to this camera so they can see the oh that's right I am because that solder bridge that you just did see well you can see this solder bridge that I just did but don't don't worry there's more I've got a couple more they used to do okay so that's that one this is our high digits for YouTube so this is gonna be our second display in this series the first one because the first display in the series I didn't need to do anything that's if I get them both in at the same time so that's that one there I didn't need to make any modification but this one I needed to drop in that solder bridge on a zero so those are done next up we have what we do green green seems like a good color for Instagram or maybe Twitter Instagram let's call it Instagram so this will be display Oh X 7 3 which requires a short on a 0 and a 1 so I'll be those two Brian just joined us in the chat Irish Brian who II didn't think was gonna be able to make it because it's so late in Ireland he's up late he's the one who broke the API libraries that I used for developing this project he wrote the Arduino Twitter API library the Arduino Instagram API library and Arduino Instructables API library and there we know YouTube's API library so thanks Brian we're making oh that's really easy to use no kidding he also created the code we build one of his projects on this show last year which was his his like traffic display yeah yeah that is one of my favorites in fact I actually have that now hanging up in my office at home we installed it in a piece of artwork that that I had saved aside for many years as a gift from my wife before we got married and it's I I look at it every day I love it thank you Brian thanks for for joining us too on the on the chat and I even forgot to really talk about this show for anybody who hasn't been following that so this is a show where we build projects sometimes straight out of the pages of make magazines sometimes from our community like this one live on the air but this is a fun one because well while this show has only been around for two years in this version the the name make live has been around for quite some time primarily because of You Becky oh yeah that's true I did used to host make live in its first iteration in 2011 and I think it was conceived in 2010 executed in 2011 perhaps with Matt Richardson and I hosted a biweekly webcast that was it was we had guests and we did like video segments outside of the studio that we would bring in and live demos and it was really a lot of fun we filmed it in the old MakerBot space here in Brooklyn okay did you guys broadcast that live per the name yeah we did yeah well yeah I mean we on Ustream actually and then because YouTube streaming was you like hard or it wasn't real yet maybe I don't remember exactly why we were on Ustream and then we would put the segment's later on YouTube so you can find them on this channel and then all playlists probably buried yeah somewhere all right we would assignments out like very short for him each instead of the whole show you can watch the whole show as a podcast do you remember those I know those are real again I guess maybe because the video podcast and yes we had all these different formats we did broadcast it live and it was a ton of fun I think it's best experience via its clips shows there's two like clips videos best of best of season one mm-hmm that are a nice representation of what we got what we got up to each show how to theme it was a lot of work to be honest it was really fun cool okay so now we're doing display Oh X 72 which is a one shorted and then we're and then we'll just have one more displayed view and then we'll be almost done and then we need like coordinating those two things like yeah Jess you call it in the code and the things that be shorted on the board and we're tough to keep in my head at the same time I did just notice in this listing here that the the numbering got a little bit out of sequence so I might need to do a little bit of code modification I almost wonder if I want to make a notation on the back of like just write in sharpie what the address right you have this space you might as well yeah but once you verify it with the code right so you can be sure I'm supposed to wait kind of worse than that knowable yeah right so that is hex 72 and then we got to do Oh x7 five there's a zero and a two and then we're done yes well it's your with those display backpacks it's so much easier than the old way you guys remember the old way right I actually haven't messed around that much with the 7-segment displays before before Adafruit made it really easy each one has an LED right each segment is an LED so you have to multiplex a bunch of LEDs to get any to get one digit working and then you just need you just need a lot more IO pins then – yeah a lot I think that's why I avoided it yeah so it's a lot of solder connection and then the code is a lot more complicated – yeah but the backpack really brings down the barrier to entry for this type of project yeah the only other displays had really worked with where the where the LCD displays I bought them from sane smart that was like that the two by sixteen character displays but I think they just used some analog source rated for the data connection between it and a Arduino and then you just call it in the library and say here have it write this and it goes okay well I couldn't touch it – yeah okay so that is all of those taken care of I get a pair of these back all back up again so at least I have them organized so that's green I think I already did get these all mixed up go me you're ultimately talking about it as you're doing it I should probably correct for that because when I get these mixed up I'll get the colors mixed up and that's that's not gonna do me any favors so these little coats here those are the colors is that now that is that the indication the no this is the address this is the location of them okay why don't we do it together I have the list of what they should be and and yours should be just slightly like I know the addresses with the pins shorted right in front of me why don't you run by me yes so my my concern here is that like these two should be matched up but the problem is is that the one in my right hand is green and the one in my left hand is yellow so that's good okay do you have some solder wick or a desoldering bulb tool because it's pretty easy to fix yeah I just need to grab a solder sucker which is right at my feet kaboom if I wanted to leave and go get over to my backpack I have a really nice one that I keep in my bag but I'll burn Japanese one yeah that one is silly I talked about it on the cool tools podcast recently I can't remember what the name brand is but the little Japanese silver Japanese solder sucker with the red button yeah I still like home tip is what does it right because you can make that really good seal that there's that aspect to it me my other favorite part of it is that I have relatively small hands and the with what with this one I always find myself needing to either change my grip or like get the other hand on it to do that and with the the engineering one I can keep my position in my hand and there's reach up with my thumb and reset it without having to take the other hand off the soldering iron and that that's my favorite feature of it that didn't yep get being able to get the really good seal and and actually lift off a good amount of solder I feel like now that we've talked about it so much I should go grab this umm we can show everyone let me go grab it so you don't have to rummage through my bag but yeah let me let me get back how about I grab mine okay you could do that easily accessible one okay so I am trying to keep this straight so this is yellow – and yellow one needs to be what color using yellow car yellow I think it's going to be Twitter so Twitter hi digits should be a zero shorted and Twitter low digits would be no alteration although I think you're reading like I'm gonna like the first two displays are gonna be YouTube and then and so that should be the location it's no alteration and the high should be a 0 okay and I think that one is correct nothing will have been read okay and then which spot is Twitter going in a second at the third spot third spot okay third spot is high digits a 0 and a 2 and low digits a 1 shorten a 0 and a 2 and load game Watts is a 1 I did do this right okay so this is Twitter low digits in yellow hooray okay and so now I'm looking at green which is gonna be Instagram and that's in the middle spot for low digits or high well the like of this week never yes in the middle stack yeah in the middle stack the high digits is a two shorted yeah and for the low digits a 0 and a 1 shorted okay now I'm now I'm realizing maybe I didn't have twitter as correct as I thought I wanted it to be as I wish it was but we'll correct that after I correct this so you said I'm not using this outer sector so now show them using I have shown of the power sector in my best Vanna White ability I'm ready and so I'm sorry running that past me one more time this is the low display for incident mental in the middle in the middle in its meister games in the middle low for instagram should be a zero and a one shorted okay so I need to pull this bridge off of a – teamwork makes the dream work like that shaky hands sure don't that's the wages of doing stuff live maybe I do need to get my the good one I'm not sure fun I wish I could like solder suck it through the screen you got it though you just need to break the reach you don't need to remove all the solder that looks that looks like a broken solder joint yeah really good focus on here and then for that one you need to bridge the a1 instead yep I think anyway I mean I'm reading my own tutorial I hope that's right right no guarantees here I also I didn't use my networks only my youtube and my Twitter have over 10,000 so for my Instagram and my Instructables networks I only used one of the 7-segment display so you're using so I have addresses written in the tutorial for displays I did not actually install yeah I write in all fairness did you keown Lee has I think 3000 followers on Instagram so if you're not following them on Instagram do so that we need this extra display but right now we diner me you tear proof right I was really trying to cram it all into this 5 by 7 frame and I needed a place for the microcontroller to go and if so when I outgrow this display like I'll have to put it in a bigger frame fits the this like the displace don't go all the way across the area that would be taken up by more numbers is actually where the note of Cu ports in so I did it by force of space and for you know to reduce the cost of the project if I tell installing those extra digits for me it's like a rite of passage when I make that milestone but you're making it as a gift so it's like a different you know correct number on this past me again for Instagram hi we just want a to Greg's awesome okay if you have in the middle of the sign that's correct yeah and then for Twitter which will be on the bottom hi I think we need to correct low digits first and you said zero and a to low digits for your bottom position display should be just a 1 just a 1 Haydn's for your lower position display should be a 0 and a 2 okay and this is so I need to correct both of these because I have this should be high digits because this is yellow to just for just to keep my notes straight thank you okay for Twitter yellow and this is so I need that should be the way low digits is with just a one soldered correctly correct a one for low digits okay so that's wrong although maybe I could just ruin my life by just changing the labels nothing sorted in the code as long as your as long as the high digits and low just so same color we can switch which one is in which slot yeah but did you solder your high your top position signs correctly yes because then but then the fastest thing is to just adjust the lower ones yeah alright so to save on re soldering you're going to label it I'm going to real able this one because this is correct for low digit Twitter at the bottom display is just right yeah right low digit Twitter on it okay so that will be yellow no longer two but one it has a 1 sorted yeah it has a 1 shorted okay and now for the highs I need to right now I have a 0 and a 1 shorted and I need to change that a 1 to a 2 I see so you made you flipped two of them that's the Misti yeah and unfortunately you flipped to that where different colors from each other yep oh well that's good sleuthing I think that this kind of project lis bugging is one of the hardest things to learn so I think it's one of the most valuable things to offer up to a live audience like this and also it's impossible to teach it like without working through someone's active project it's impossible to teach this in the abstract to be like oh well when you have a problem just use deductive reasoning to figure out what the problem is but that's so straightforward and we saw a big sauce to it it can be confusing I'm also dyslexic by the ways I I mean this is this is the thing I always get terrified of when I'm doing these live streams of like what if it all goes wrong and then I eventually realized wait that's the fun part fun for the audience if you haven't a positive mindset about it it can be really fun Pacific but as soon as you start putting pressure on yourself and getting frustrated then it's time to take a break I think I think it just came with it really just came with a realization of like once the stream starts it can't really go wrong it can just slow you down a little bit it can only go wrong but if you like your internet goes down that's the way I know it like it's only broken if you're not online it's not broken anything you do or or if your audio is on the wrong frequency then yeah everything else here is just part of the show alright and and also like you know getting feedback from from digi-key they're like we really like it when things go wrong I'm like I hate it when things go wrong but I see your point well yeah it shows the real like problem solving aspect of it and then yeah although here we've robbed the audience of the payoff of me hopefully getting everything hooked up and being very pleased with myself and nothing being right so there's that part of it here we are you Tyler we won't let that happen here here we notice the problem before we got before we got too far into it okay so the next one then it's not the end of the world because like even if you're the displacement mismatch like you'd be able to fix you'd be able to fix any of it in code but it just would be like a little bit of a headache where's the headache if we just sorted out and your code you already pre-made your code right yeah so but we might who knows maybe we'll need to dig into there later and do some troubleshooting the next thing I need to do is start making the big wire loom for for this project and the cool thing as you mentioned the cool thing about I squared C is that you can run everything off of essentially a single wire or a single pin from your board but I need to branch that so we're gonna first thing was we we have our 5 volts or the voltage from the board and so I need to take this and split it off into multiple branches so that then it can reach all of the displays and I almost wonder if I should start laying out this piece of foam core so that I have all of the everything here kind of in its place so don't make anything too short which is sort of be well this got it to do a bit of design work here and and lay everything out then cut holes in this board like your intro to magic I'm Tyler this is uh that's hot recommendation from our good friend and now once again regular make contributor Donnell Bell Bell got it from me it was a facetious comment oh I had a feeling that's where that is a good call over here there's no magic arms and Donald Bell is in diapers that's not true is it I claimed to be using the magic garment to make your scene with luggage that's like I don't have many many claims that I will proudly stand on top of but well it's fantastic so yeah I agree popularized thing um I never really thought that they would I mean I knew that they were good but my I mean we is these Canon c100 here in our studio and and I never thought it would actually be strong enough to hold one of those up so and it's it's a little wobbly for them again you notice when I'm like make a little focus adjustments it has a little bit of shake to it but yeah these things are great use them good hands in hands in shot in foot it's yeah tough town hands in yep let's see yeah right cut this tripod mount or sorry what's about please the tripod plate mount on it yeah but I can swap out cameras Becky you'll be happy to know that Donald Bell is watching on the Facebook okay different tap hi Jonathan and great and he is giving you all the credit oh it's so sweet I guess the person who doesn't know I need to grab a pencil so I can do my layout marks here really quick I'm gonna run and do that okay so Becky I noticed this you're using esp8266 for this project you've got on your on your instructable page I think you've got three or four esp8266 projects if you count the the YouTube stats count or the other social stats counter you've got your weather tracker and a moisture meter that this powered by esp8266 that you could sleuthy i wouldn't have been able to tell you how many on the top of my head that I have made lately and you got them all yeah I really love that little note MCU for it because it's so inexpensive and like when I want to you look for the first one that I made or this youtube subscriber counter I used the Adafruit Kazaa feather huzzah because it they make a feather wing accessory that I could just plop right on top and it was actually way less weight easier for beginners you didn't have to even figure out which pins are the eye screens you just put the whole thing in but if I'm doing anything that it's a little bit more expensive so the known MCU board is a way to get the esp8266 functionality it has a little bit of a different can pin layout and it doesn't have a live polly charger so when i want to put a project that just hangs on the wall i don't need that extra battery circuitry to be paying for so it's nice to use the no tips new board it's not that I'm going to leave plugged in all the time but yeah I did these two social strata checker I did a coil moisture meter which was for my solar power class on the instructables website if you go to slash classes I wrote a couple electronics classes there Arduino internet of things using the esp8266 and solar and so the solar class uses it's an example of like an outdoor solar-powered microcontroller project and you can really change out the soil moisture sensor for any kind of sensor you wanted whether you like track the birds at your bird feeder or do any other kind of weather monitoring that project gives you a good template for it so there's a tutorial there on my instructable site yeah yeah and you've got you've got quite a quite an Instructables page we've got a lot of a lot of content uploaded there but now you're new that's that's one of your main roles is content creator yes so and I've got promoted I'm product manager and content creator now so that's exciting where I get to I'm working on some Tinkercad Arduino lessons if you didn't know Tinkercad now has a circuits editor inside I used to be a circuits tayo and it's gone through a couple different Autodesk product iterations and so I'm working on sparking a curriculum using that circuit simulator which is really cool because it's it's kind of like Fritzing in that you can make diagrams but it's also a great part of simulate able so you can like design your whole project including the code watch it run and then build it from your own diagram so that's a pretty cool thing that you won't see on my Instructables page because I'm publishing them on the take your cut circuits and start kerbals page and linking to them frequently you can also embed those circuits like simulations inside your own tutorials so you can use it as a teaching tool and documentation for your projects it's really about the way they've expanded that i'm gonna take a cad fan and you know i think that it's such a great gateway tool it's you know it's so accessible for just so many a range of makers from from young to old you know from new to hey I'm a pretty experienced but I just need something really fast yeah yeah let's go congratulations Thanks what do you – hey what's that oh yeah switch over let's see let's show everyone what wait what you're cooking over here oh I'm just uh I'm just doing a whole bunch of measuring and marking here I don't even know if I have that really good I have this nice macro lens oh that's right we're sitting on Becky here no I'm just mark them as I get this thing over here I can see I have the show open in another tab like yeah Helen just call the code from here like you used to that's fine no I'm just doing the the markup and layout here and measuring and all that spots for for the the holes I need to cut out through the displays and just as a way of getting everything kind of laid out and Ryan reminded me Mike of another esp8266 project that I did that I forgot there's actually two more I remember now that he's pointing out an earlier one besides the weather display also made an internet Valentine so it's like a telepresence thing where you each have the same device and they both activate the little hearts on each other so you can have them as long as the connection the Internet they'll make each other light up whenever you press the button well 10 minute that was last that was Valentine's Day 2017 and then there was another one I scrolled back oh I made a lamp controlled by my Amazon echo so I used an esp8266 to feather huzzah with the real a feather wing to power relay to control a vintage lamp that had this wooden face and I carved out the base and put all the electronics inside so you couldn't see it and then ran the FOMO ESP firmware on it that emulates at the time it was a Wii mode of ice now I think it Emily except for looks hew device that that makes it the setup in the app super straightforward so that it just looks like any other commercial IOT product when you go to set it up through the workflow in the app so that's that was like an echo turn on my turn on the light thanks Brian again Brian takes a day Brian's like you didn't list all of your he missed my crown cause my project like very prophetic this money we made internet isn't this internet internet great you like to use somebody's code and then that person is like oh thing thanks for using my code and then all of a sudden your friends and now we're real friends that's great that's awesome I only had kind of one experience with like I made a project and put it on Instructables and then somebody else found it and made it better and that was the a time-lapse panning device and I I didn't really understand the hardware design or what like hidden resources people had fairly building robotics or things like that I basically built it of garbage that I found in my garage and then somebody else found it and then put it together with a bunch of stuff from like active onyx and things like that I'm like wait that that design is a lot better also wait you have my code running on your your device like people actually want to use code that I wrote why most alarming time for me okay that's an alarming realization for many makers I think it's like getting over the idea that like yours just sharing it will give investigate your own motivations for sharing right and if you want to share but then you're surprised when someone wants to consume what you have to share then you got to reconcile that in your own time I mean it was never it was never like oh no they're using my code like like that I felt protective over it that was more of Ono somebody's using my code what disasters will lead them to well that's what I mean like you if you're gonna put it out there you have to assume somebody's gonna want to read it yeah otherwise putting it out there but it was cool because then I have this project and I end up bill rebuilding his version of it with the better Hardware design for myself I'm like oh this is so much better and great I love that about the internet where because I like I'm not that great I'm a coder and it's awesome to be able to leverage other people what other people consider fun and easy to do in their free time like make Arduino libraries and then what I consider fun I need you to do in my free time or you know at work in my case them to build biblical project and then to have this kind of virtuous cycle happen where everybody adds a feature when they make their own version I think it's so fun yeah it's funny I see that a bit with the people that we talk to about putting projects in to make magazine and the stuff that's on the technical side there is a skittishness about sharing code and being having programmed something for themselves versus for publication difference between codes you're right it just barely works and code you need to be able to answer questions about or have someone else understand without having written it so people often say oh I'll publish it when I get a chance to you know comment the code and it's better I feel like it's almost better to publish early and often and then revise things it's one of the reasons I really like publishing online versus in print is that like you can somebody ask a question you like oh yeah whoops I here's a comment I here's an answered your question and I improved it something next person who has that question will see the answer right in front of them in the sketch but it's true that like you the things that you're you're able to make are like at fit very edge of your skills right and your ability to then teach that subject or relay that information to others depends on the domain and electronics is one of those two encoding especially is one of those domains where you can make it work and you know how it works but it's not ready for someone else to easily grot how it works without further explanation so it is an exodus to be able to then share your code with others equally and it's nice and peaceful oh yeah who knows everybody does it alright I've got the first one of these windows cut out and now I get to moan of truth make sure I measured everything correctly trait around the display that's what I would have done I would have just traced around the display and maybe use the ruler to make sure was little yeah I'm trying to like do a little bit I'm trying to even though I'm not a designer don't ever have me design anything for you at least not like graphic design but trying to like get good spacing things like that oh sure yeah yeah yeah I think of what I would have probably done it's marks the center of each and then I balled it and trace them all at once if I'm just sharing and we're just sharing yeah I'm also really good at over complicating things so that's you guys are missing some exciting cutting action right here he's free handing it don't don't say that when I'm still cutting towards my hand did you ever get that that did you miss out on the design school hand injury then that involves the knife and the ruler no when I see where this is going there's a very telltale freshman design school injury that everybody gets when they do their 3d design homework at like 2:00 in the morning and they come in the next day with like their handle bandaged up because they cut the cord with their finger up hanging over the edge of the ruler and I lifted my I anticipated this and always did my 3d design homework during waking hours where I was not sleepy and only did homework with non sharp tools at like 2:00 in the morning which is why I gotta be and drawing but I never cut my finger in while I was in undergrad I did it in grad school instead I was in a welding class because I was although I was in an MFA sculpture program I hadn't taken sculpture undergrad so I was learning how to weld and I was in that class of undergraduates who were ready to exhibit their work and I was making nametags for our little exhibition and it's like let me show you how it's done kids you make the nametags with the utility knife and the ruler and you the brand new sharp blade and like I didn't even notice I had cut the corner of my finger off until there was blood everywhere because the blade was too sure oh yeah we're about to see the wages of cutting freehand and trying to work quick so that's a bit of a chewed up thing here we'll try to use a future fine oh well nothing a little gaff tape can't fix correct beautiful correct well so we'll have time to make a non live broadcasted foam-core cut out for next week at Maker Faire so it's not perfect that's a pretty easy thing to rebuild yeah well we'll pretend we'll have time to do that okay so look up the measurements don't bring anyone we'll just knock out these other two we're gonna go with a 1 inch spacing between each of these and Teller switch the camera over this one one of our one of our viewers is asking they want it they want to see the action oh they want to see they want to see my bad layout skills okay see if we can get this sort of in place here yeah there's that so just putting in a little mark on either side this will be the top of the next row and let's see jog my memory here these are one in five eighths tall yeah I love your macro lens I do too wait did I say what a 5/8 that's correct yes yes one in 5/8 yeah they the macro lens is a little bit tricky to work with here because this is where I really wish I'd also had that kind of wide lens and I have on the other camera here and it's with the magic arm and a project of this scale if you're doing a super tiny thing the macro is great yeah which is a lot of what I do with this lens is the tinier softly showing all that soldering details but here I'm just gonna put your very precise measuring Detailers is also very maize yeah just getting some part of what I'm doing in the camera for him all right so there is that and I'm actually really surprised with how I just put a fresh blade into this the other day already I feel like I'm really dragging it gonna make multiple passes funk Correll so it dulls the blades pretty easily or it has somebody been using your knife well you aren't lucky I hope not that's your personal knife right it is funny if someone was stealing it out of your pocket and cutting stuff I don't know foam-core kind of it requires like the sharpest of sharp knives and then in order to not make it get shooed multiple-access yeah let's I mean I'm definitely doing multiple passes here maybe I'm digging a little bit deeper on the second one one getting through the the foam layers and then a couple more passes to get through that the back half my favorite knife is my alpha twist-lock like it takes the whole strip of like box cutter blades the break off kind mm-hmm and when you tighten it down it like clamps very tightly around the edge of the blade like near where the blade touches the work so it keeps it nice and steady do you have do you have them close by oh yeah cuts me while I'm not sitting in it no we're we're just watching Tyler's cutting skills here yeah I mean if you've spent any time around me in person eventually I'll wave this thing in front of you and tell you you should get one because it's one of my favorite tools the Gerber oh wait I'm ready to show you my name not the Gerber knife it's the Olfa night yeah and it takes like the regular box cutter blade so it's so you can like snap them off when they get dull and then but if you keep it nice and short adjusted if this little ratchet clamp really tightens down very tight around the this area this is what differentiates it from like a $2.00 box cutter or the list lady doesn't plop around so you get a really nice precise hold on it so that you can really dig down hard and then it does get dull I just break off the tips of the plate so that's my favorite knife I've had it for 15 years and it's still holding up strong awesome yeah I came to this one a few years ago this guy and I love it because it folds up really tightly it goes like just fits in a coin pocket or something like that and then you know this has one of these standard utility blades which means that I get to have a knife that I don't ever have to worry about sharpening which means like turn the blade around when that first one gets dull and then replace it right exactly you know they'd flip it around or swap it out for a new one because I I don't have time to keep a knife sharp alright so now we're on the back side here just kind of evening everything up and and Becky we were talking just before we went live about makerfaire you're gonna be there I am gonna be there I'm speaking on a panel on Saturday at Maker Faire New York at 4:00 p.m. on the DIY creator stage and it's panel about the future of online products hearing and my colleague argued love will be moderating and the other panelists will be Sophie Kravitz from hackaday dot IO Alex glow from hacks Sergio and Clare white mark from makers chair so all of the different platforms shipped sharing platforms will be represented and will be having an extra session about those and project sharing that's a powerhouse lineup that's an F everyone on that on that panel is superstore it's gonna be good but you know we're up against like at the same time is the Mythbusters junior panel which personally I'm pretty bummed I haven't convinced that wait no that I don't think that's the case because well because I'm I'm all that also coincides with what I'm doing at Maker Faire which is running the Maker Faire live stream which is also graciously sponsored by digi-key I buy I am I'm gonna be featuring your panel and the minister's junior panel maybe um and that's because that should be on Saturday at at 3 p.m. 3 ok so what made me think that as I was talking to my friend Lenore Edmond who's that evil mad scientist laboratories she's doing a panel called ask a maker and it's overlapping only 15 minutes with my panel and so when she said but I was I was grouping our time slots together when I said about the Mythbusters I'm like I won't probably won't be able to make it to it you know what I mean yeah yeah the same time ish competing for the first similar audience because some people might race from one to the other but yeah because I was you're gonna raise your money and also like ah I you know who knows to make her fair but since when do they run on time by that time in the day I'm actually starting to yell at people to keep their schedules on stay or keep their stage schedule schedules on schedule because I've had some run-ins of like where one panel runs a little bit long and then it goes over and then then I'm go you know say I'm because I might live broadcast goes from multiple stage or covers multiple stages and if I have one that runs long that I am on right now and I'm going to one that started early I ran into this with Maker Faire New York last year where I missed almost entirely they talked from the astromech builder's club and everybody was really upset and that I mean I I think that's bad for our live audience it's bad for an in-person audience who's like yeah I want to see astromechs getting built and that's gonna be here at 4 o'clock well Oh what happened at 3:30 so I'm definitely putting pressure to keep keep the schedules on board so that I mean I know it's hard to create said event so it's a lot of moving parts but see you then yeah first person next week and I like that I don't have to travel although it is a little bit far from my house it's really nothing wait a minute well but I will point out they you folks generally stay much closer to the event Browns then I live so there is that that I have like the daily commute thing or like getting out there like an hour but to be honest there's no rating I will ride a motorcycle so it's pretty fun yeah that's that's one of the things that done having been doing you know different kind of trade shows for a while it really does helped it you know even though even if you are on the other side of the country I mean sometimes it's rough when you're doing a show like this like going home and sleeping in your own bed and feeling like because you I don't know like in a Bay Area I tend to stay in a hotel even though my own home is not terribly far from there just because then when you're working like 18-hour days trying to act like a normal person to the other people you live with is is tough that's true that's why I insist that all the normal people I live with experience make repair and this similarly intense capacity that I do so we're just one team one dream yeah that works too but I gotta come home and you know to meet the dog I'm an old cat who needs a daily care so it's easier for us that way and and it's also a good opportunity to get some visitors like out to Brooklyn I'm I'm pretty close to the let's call it the hackerspace and my series is your hackerspace and I'm a member of so it's fun to be closer to those other city events be able to be a good host to people who come in from out of town I still need to visit that space at some point well your if what you know your schedule permitting I'm happy to show you around cool me too great you don't have already heard about your schedule at all big time no that's that's that's the type of thing that uh for those the day before Maker Faire or the day to a couple days yeah that's a very perfect thing that I would love to yeah any time let's know you said you're busy in the evening but I could see it yeah yeah Rena came when she visited not too long ago she was I was out of town but she visited the hackerspace I remember seeing it on the mailing list cool no not quite ready to flip that over yet get it so Dave Darko's saying in the comments here that he was there last year at Maker Faire New York it was super hot reminds everyone to bring water which is just not not a bad suggestion although I've been watching the weather and it looks like it's not going to be as a scorching as opposed to be I mean it depends right now we're having some really cool weather because we have this big hurricane I'm hovering up or you know slowly moving off the coast right this great need for like a whole week it's dropped the temperature quite significantly we were having really oppressive humidity but you never know the end of September can be jacket weather and it couldn't also be 85 90 degrees depending on what weather systems are coming in so I would definitely like plan to stay hydrated anyway cuz you're doing a lot of foot work yeah yeah for fun you're gonna be doing a lot of talking you go to make your ferret and that makes you get perched yeah less last year was crazy hot but reason water fountain I like the water fountain on the ground floor and I'd say though the water is very cold yeah we're anomalously cold cuz they're a year before that it got cold and rainy all weekend yeah they also do that it could also rain all weekend which is in the fall not so bad by me like I like the cooler weather I don't mind a little moisture but it's not so nice for everybody exhibiting because then everybody about their outdoor things getting wet yeah but not so good for video gear right right bruh hey or attendance well fewer people look up yeah alright so there's all of our panels for the displays again let's see if I can match everything in here and as my two yellows we're not gonna worry about maybe I should worry about ordering them because then I might just solder these in place and I need to remember some pushing them in from the backside okay so one goes on the right side dave says that this weekend is maker faire Hannover the biggest did probably the biggest one in Germany that's right yeah that's uh one of the ones I haven't been to yet but it's produced by our our German partners like it'll make dot de yep X Oh lay back yeah and they from the Heiser team for the the CT publishers well show me that I can tailor you to pick me an upside down um one of them upside down the decimal point needs to be where there's the single decimal point that needs to be facing down okay I was wondering about that because the the silkscreen on the back is right side up in this case but that decimal point does make a lot more sense on the bottom no good things to learn now but although that would have been fine wouldn't have known it until but good so you get that ahead of time that should make wiring the wiring layout a little bit easier too although now I've reversed them I think so I'm using a different product than you I don't remember if I work that way or the other way around look at my tutorial photos and see if there are any cues I mean sideways there is no there's no up-down of the uptown is ninety degrees so if there was no similar thing going on at night yeah um well there's one way to find out yeah mate and that's start wiring these up so so got our soldering iron going you don't have any female to female hitters um I probably do okay so that's one these are reversed okay so but panel one there and two here okay I mean lack says that there's an Ottawa Maker Faire happening on the 29th that's the village right after New York yeah as is the Milwaukee Maker Faire it's Brandi Kirby stuff with Kirby is as mentioned that – there's a lot citizen it's a bit it's a busy time of the year yeah I mean the weather space right yeah yeah a lot of good shows out there it's great how many have developed and really turned into big events all right so the next part of this is I'm just going to make solder connections for basically all the different displays and then worry about wiring them all together and I also have just noticed that I'm I seem to be working with stranded wire which I don't think it's what I ordered but it's what I got that might make this a little bit more fussy to work with but that's okay there's a little classier to solder you got to make sure you get all the strands in so that they don't wiggle around and short out with each other but the upside of stranded wire and your finished product is that it'll be less likely to break when you move it around say if you pack it in a suitcase or a box yeah because the work flexible the stranded wire is more flexible or like me where I crammed my wires so tightly inside a shadowbox frame that like I wasn't looking at how the wires were getting smushed I was just kind of like pressing and hoping but everything stayed it's quite it's quite full I think I'm going to you a couple of these up so I can just knock out all that solder connections for this one all at once yeah work smarter not harder although you were really working the smartest you would be you just be plugging in female header wires to that segment well you know then it well if it comes unplugged and the people at the digi-key booth can't fix it like that's a problem too so it's always important to use the right method for the audience right like my stuff's if it comes apart I can easily fix it but if you're designing something for someone without the tools or the knowledge or both to use then you need to make some you know insurances that it's going to stay well this is where I have really done myself a disservice because I'm going to be directing the livestream broadcast from the digit key booth right next door so I'll be in the middle of my live stream and you know I don't know David will probably come up to me and be like hey Tyler our display stopped working I'd be like I I will get to that well you can you can have the page meet I'll come over here we go like anybody who's watching this stream who reads the tutorial and then comes to make your friend eager would also have the tools they would need to look up in any way and that person will get free tickets to make her fair next year yeah right no all right oh it's all time it's gonna be great it's not gonna break mid-show nope none of that will happen good admire and your soldering your connections but didn't look like stranded wire but maybe I can the purpose in focus now it's not that yeah that's it yeah that's it stranded in the chat at the moment you inserted the wire yeah champ Bryan says finding out I can help babysit beside we'd love to see you Bryan wait a Mayan are you coming to make for me not even you made a joke find me out I know and I'll help okay cool oh yeah someone else what we're doing to recap what we're doing we're making a social stats tracker display that uses daily change I squared C plus seven segment displays to show the social stats followers for three different accounts on the same display using one note MCU esp8266 yeah yeah and Tyler's currently wiring the 7-segment display you know how much power those bigger ones use is it considerable um that sounds like an excellent thing that I should have determined ahead of time I'll look it up they're just like the really big ones right that 1.2 are they the 1.2 inch ones yes yes how much government do you use then your legs are own okay that's all better there may not take me of course the power lookin very simple it's displayed on the screen nice to know what the max current is because you're pulling the power through the note MCU voltage regulator make sure it doesn't overload that sometimes I make this blazer neat though I mean it it's just one led per segment and the lensing is what stretches out the light so I wonder how much more powerful the LEDs inside that giant look that's a good point because they're not like 1 watt LEDs or anything they're just probably just trimming them I don't know I don't see any current but we'll see it'll either work or it won't you can always just hook up the bypass the the microcontrollers power and hook it up directly to the power source that the microcontroller is feeding off of yeah Brian mentions do that it won't have all the lights on with the backpack exactly yeah all right display like on the wall and you just how much have have your follower counts changed since you built these projects well the first version of the Youtube subscriber button live display that I'd built list for under 10k so and I believe when I was building it I think there's shots of 7,000 so I had 7,000 followers when I built that first one and then YouTube it's gone has exceeded 20 recently for me 20,000 so a lot that's my fastest growing network and Twitter I thought was gonna breach 20 recently but then that thought purge came and I guess I had like a couple hundred followers so whoa back a little bit on my youtube still at like nineteen five and then yeah my Instructables follower count has gone up a lot because like people don't don't generally know that you can follow people on Instructables so that's a thing yeah yeah just by making the tutorial about the social status tracker you get social stats increase because people are interested people are introducing those platforms aren't gonna follow you on those platforms it's kind of it's very meta project in that way right funny well shout out your your channel names I know you you tend to use its back oh my nice treatment my handle I'm lying I mean you can just go like search Becky Stern on YouTube and you'll find me but my handle online is by cat we have bek a th WIA and you use that for almost all of your channels or all of them ever taken you own it I own it on Twitter and used and YouTube and Instagram and Instructables and wherever wherever I need it use your name that's my username that's good it's me me you had me prim enough what I've got I've got mine almost every spot except for Instructables for some reason I didn't get I just I just used my first initial last name very very corporate but for some reason on Instructables I couldn't get that so I just put that what I just did Mike J s good old Mike JavaScript that's me you should get Mike a dot J yes that'd be good you get people hitting you up for your JavaScript jobs though I I recently learned an interest a interesting lesson in not owning your username on every social Channel oh yeah because on Twitter and Instagram I post as at photoresistor that's right you have an electronics component username foot trouble but not on reddit oh no and somebody that photoresistor on reddit made a threatening remark about our president oh no and ended up with me having a lengthy discussion with the Secret Service who weirdly enough also worked directly upstairs from us here in the office Oh what are we gonna coincidence right well and I'm not gonna I found out that dumbbell head at Donald on Twitter so that's that's roughy yeah he has different experiences with that yeah I do get thank you stars pretty common name and although I do outrank them all on Google sorry oh there Becky CERN's there they are around and I do get emails for them sometimes from like their you know their great-uncle sends around to how the potted flower is doing and writes my address instead of the real whatever Becky's turn but uh I try to wish the other ones a happy birthday on Facebook because I think it looks funny when it's like Becky Stern writes on big these turns welcome to birthday yeah of course yeah they're fairly famous one of those is Will Smith formerly of tested calm who has Adam Savage yeah and you know sometimes people yell at him when like Jaden Smith is being weird you see and what's my ordering here black red I yellow or green is my data connection and yellow is my clock he's got to keep that consistent across all six of these because they do a whole lot of wiring Mike what were you saying but you think this one's gonna go really quick oh yeah I think I said that every time yeah yeah we try not to say that no I think I also started that sentence with I'm gonna jinx this this one feels like a fast one I think I think you didn't actually say that so breather don't like it went by so fast because we're having so much fun no it's I agree but it's true because he doesn't have the header wires that you just plug into the displays it's gonna take an extra at least a minute yeah Becky what new projects you have underway right now it's summer still so not a lot I'm admittedly not a summer person but uh I love you let's see all right since you have me while I'm at my desk I can actually pull up my projects brainstorming listen Lee you know what I had mm-hmm well I wanted to for a while I'll make a foot pedal connected to my door buzzer so that the dog can bust the door see like when she's home alone she's closed in a room so she can't like she wouldn't be like buzzing strangers in but when I live in an apartment and when like the delivery guy especially for like takeout food comes and buzzes the door I have to get up go over to the intercom and like press the buzzer button to like open the door downstairs for the delivery person to come inside and then wait there for the delivery person on the stairs so if I can have the dog do that initial action of she always comes to the door when the buzzer rings so I as well have hurricane here to press on a pedal that then buzzes the door so that I only have to enter the wait I can just it's a first world it's a total luxury niche product right I thought it would be pretty funny to make the video though yeah the doctor looking in the delivery the food delivery guy and she I thought of it because she does come to the door whenever the doorbell rings so and she's very food motivated so it'd probably be pretty easy to get her to stomp on a pedal so then that's an idea I have um in a buzz a little a see know so I'm like hesitant because I will put up the buzzer panel and the buzzer panel is AC and I don't know if I want to add another feature to it anyway it's just you found the brainstorming list um as many things I'm sure you guys are familiar with projects changing as go through the different phases of the brainstorming list there's some furniture projects I want to do around the house I have some plywood left over from a furniture storage wall cabinet project that's almost done so I want you see that pine which makes it like floating bed side shelves I haven't I tutorial idea about teaching people loosely how to translate an idea into code I think could be a useful tutorial to write but that's not like a project that I want to film it I think I want to teach and just like a mindset thing and then yeah I don't know there's a couple of other agility things on here I come it sounds a little bit like the kind of mindset you get into your first year of like learning any programming which is you just find yourself taking everything you do day to day and then just turning it into repeatable steps like how do you make breakfast well I think if you had to teach someone how to make breakfast but you only could do it in texts like what sort of techniques would you use I mean I think it's useful I teach a classes in the fall semester at SVA this program called products up to sign it's a graduate graduate program in product design and I teach my students Arduino and some fabrication stuff we do some crafts like soft materials project and hardly any of them ever have any coding experience and so the idea came from teaching them about like how to so you have an idea for a project how do you actually break it down into the code you have to write in order to make it go and I feel like that's often one of the hardest things for people to conceptualize when they're a beginner and really overwhelmed by the idea of writing their own code my list is really silly waxed canvas something like that's what gets put on my list like oh I want to make something with wax canvas just wax canvas something nothing that's what it says in it is it as I think I've heard I mean we're gonna be working with canvas that is already waxed or as I think I've heard to some people doing processes of tackling that yourself and it's not that hard but I could just be no I'm gonna wax after and I do have the wax so you throw it up you sew up a canvas thing and then you melt the wax onto it certain type of wax and aswangs canvas wax for waxing your canvas that's right I guess yeah I mean somebody just yeah I got the idea when I saw one of my colleagues did a wax canvas project I think it was Mike make one and I was like oh that's right why should canvas is the thing you can do it I liked sewing and I liked motorcycle stuff and a lot of motorcycle accessories that they're not leather they're made from wax canvas and I thought I never thought about it before how it gets made but it it's just sewing regular canvas and then waxing the final product yeah of course you can make things with pre-wet expanders but and the waxing kind of helps to have wat make that they water-resistant especially the seams and like I said never thought about it before and sewing with heavy materials is also intimidating but if you can sew with a softer material and then make it heavy later with this waxing process yeah that seems pretty cool to me so I think maybe like wanted to make a motorcycle tool roll or something something along those lines I've got a idea in my mind for a vinyl like a billboard material vinyl tote project that I want to do and that the sewing part of it's the part that I'm nervous about my sewing skills for terrible machine yeah right but airs at the maximum how many layers gave me something together and I possibly like four or five if you're like creating old overseas yeah and that's that you know that's my dream you know I'm sure it's gonna look more like dental floss and two pieces of paper is two shoddily crushed together but you know in my mind it looks this I've got this professional idea yeah well that you're setting your thumb up for left on if you're in your mind you have a professional vision of it and you have the breeze like an industrial mean just even a regular sewing machine I'm terrible with so yeah I start with I'm going to start with a prototype in a softer fabric to get your pattern making skills down that's a great base for any exciting project though so I might go canvass and I might go some wax oh there you go you make it work yeah you given me an idea thanks oh my friend Norman Morales is in the chat he's from the 330 ohms makerspace in mixed mmm excellent hey Norman and I welcome to say your mentioning Mike Warren I just got a copy of his new book cut in half yeah well which relating to motorcycles my ex motorcycle helmet is in that book oh really oh that's awesome yeah he was he helped us I did I needed to do a video right I was it was a video I did about how to do thread tapping and I want to get a cross-section of like what the different styles of taps looks like and the type of threads they form I'm like I think we could probably do this on a water jet if I could bother cutting it for us on his water jet that was the bait I was like I'm gonna bring you stuff to cut in half great that looks fantastic pretty awesome it's a book of everything cut in half on the water jet cutter yeah and it's you know with motorcycle helmets you eventually have to retire them after a while because that after about five years the the foam that is you know basically a cushioning material starts to deteriorate or if you drop it I dropped my secondary motorcycle helmet the other day and I'm like crap well that's it done like can't wear it again after you I'm not gonna put my nephew in this helmet that might have a giant crack in it under the surface exactly so I'm gonna where do you do you know how to recycle a motorcycle helmet once it's done the common thing that I was hear about is that you can donate them to fire departments they writing basically they love them because they can use them as practice objects for you know removing them from trauma victims and things like that so yes that's and I always hear is not every fire station will accept them but you could probably call them call your local up and they will tell you which ones do okay in this case it was people tip it was a cool and easy way to do something interesting with my ex helmet that I just like the one that regularly accepts them here in the Bay Area is like pretty deep in the East Bay and you know one where I'd want to cue up a bunch of them to take them out there yeah I'm still overdue for something like that but doesn't mean you waste that's how I get to horde the e-waste that's like well I'm gonna take it all at once right a waste recycling facility which we have a really good one in Brooklyn by the way run by the Lower East Side ecology Center the Gowanus equates warehouse in case anyone's local and wants to turn in some ways the place is awesome or by some a waste they have some they have a store where they put their like pick stuff up and they'll sell you can get like a Nintendo classic there and like all kinds of old stuff that they made working again yeah that's kind of like our the San Francisco waste management had a thing how's that I mean imagine most cities probably do but they have an artist-in-residence program where you show up there and make make art out of trash yeah making my hoarder tendencies start to tingle I might have to put that on my my my pre maker faire tour list the Gowanus a waste warehouse pretty cool close to the hyperspace walking distance Oh perfect well then it's definitely that we have an e-waste czar at the hacker space in and he takes like a hand chuck no car required I mean it's a bit of a schlep it's only a couple blocks them a bit of ish like when you have a bunch of CRT monitors you know I gave my students we started class again this year SVA started class right after Labor Day so I had two classrooms now my new student and our first project is a teardown where they they take something apart me and photographs the insides and they learn about different manufacturing processes at night every year I tell them like just don't take a part of CRT monitors and like this year for the first time like hardly anyone knew what a CRT monitor even was oh that's funny I show them a picture like oh yeah and then you showed them like the YouTube kids react to CRT monitors there's one of those maybe I don't know everything it wouldn't surprise me it's like finding a payphone that's still functional and listening to the that the the dial tone yeah I would love I would love to they let my nephew's experience the sound of that they've probably never heard it similar I'd a friend of ours and a friend of make gen Kirk and rotor a gen watching oh she has hi Jen I know that she's been messing around with do research into dial based or you know the the rotary dial phones and I remember when I first used one I played around if you keep pressing the hook switch you can basically emulate the cuz I the rotary dial when you when you rotate it I think it basically breaks the same circuit that the the hook switch does and I eventually learned that if you just like if you want to dial a seven you could either hit seven on the rotary dial or you can just tap the hook switch seven times and one time laborious Lee dialed up a friend of Mines phone number and actually got it to go through I don't know if that's true of all rotary phones but the one I think it it all my time on growing up would do that did does anyone know if that if those still work if I plugged in a rotary phone I mean yes still work the same way but landline phones if you you just have to have a little bit service which is the big one oh yeah who's got that anymore yeah well and also I guess a lot of cable ISPs are offering digital phone so if your phone is through your cable provider you're not gonna get but that's I doubt that your ronery phone would work without some kind of deal in my buffer we've begun a regular landline it'll definitely work yeah and that was my thought you know with with the TV signals all the over-the-air stuff going digital and just making everything obsolete I guess I figured we would have heard about it kind of like DTV probably would have where they're announcing it four years beforehand and teaching everyone how to make their own GTV antennas right yeah and you figure you know all the grandparents out there that still insist on using rotary phones if if that's even Wells annual income is from charging old people ten dollars a month for their email address you know so it's like mm-hmm the TVs come with D TVs and tenants in the mail so right but it's true that get kids these days they both won't get off my lawn and also will never experience TV static yeah which always surprises me whenever I see anything that uses TV static is like I know that like I think Netflix sometimes still uses TV static yeah or YouTube for like their graphic for hey this video is offline is like very understated dark-gray static display I'm like why this is video of static it's not real standing there's a similar thing with the some of the a.m. news radio channels where they'll they'll have the the live report from the newsroom little little break little updates and you hear this background noise of typewriters furiously you know it's it's out you know you listen to it go wow this is news is bustling in this in this news office right now and then you know if you think about it wait nobody's using typewriters it's the news office at this point just silence people quietly typing on quiet laptops and if you have to make a phone call you go outside and you do that separately but they really not yakking on loud typewriters no theme sound busy ya know they just create this uh that you know it's just ambience that kind of creates that busyness and you know it hearkens to that that image of a busy news room with teletype machines and typewriters and everything you know yeah my dad worked in the newsroom he's the newspaper editor at The Hartford Courant for 25 years 38 years and would bring me to work on bring your daughter to work day and I remember ordering Chinese food and being loud they were like mechanical keyboards so like but not everyone was typing so it wasn't like I don't know there were people talking and there were a lot of news station news TV stations on that was what was loud looks like it ends on here and like other ones on over here and they're trying to watch them all at the same time and talking to each other but the typing was mechanical keyboards yeah that's how you bring that sound back although I did spend one evening in a newsroom like that when I was working for CBS and I was working for a games division of there and I was in New York covering like the PlayStation 4 announcement and then coming back to this newsroom or like people recovery no lists like local plane crash I'm like I'm just gonna edit my video of that game console launch you all keep doing your real news yeah but the the now the new thing about that is I ended up leaving that office at like 2:00 or 3:00 in the morning it's pretty a pretty late night for me and then I walk past at one of the television studios there and I think that a woman was just knocking out segments were like local news stuff for the morning and issues is surrounded by robot cameras and reading off a teleprompter through all these news stories and that would just probably be picked up for syndication in the morning but that was a really neat thing that too like oh that's a modern news Lex all right not only know how to chase looks so that is for displays got two more to do powering along looking clean man yeah nice solder connections not afraid of that micro Lites I get couple this reason my macro lens outsider connections because people caught people like Brian comment things like oh you're so brave to show your soldering skills so close up because people are very judgmental that yeah that's uh that was a joyful day for me in YouTube comments of somebody actually said hey nice soldering yeah Wow cuz even you're good at soldering you still get lots of negative comments about your soldering no matter what I mean you like the Royal you yeah just every yeah tell her might make you feel good soldering skills have never tried to solder themselves or like don't know what it looks like so click spin it it doesn't like I don't know I think it is fun so Edward Hall on the Facebook feed viewer he gave you a compliment oh I wish my soldering looked that good it doesn't look good it does it's all the macro lens making it look good yeah right well the macro line doesn't let you hide anything that's for sure so you like your soldering iron tip is really clean and you're a fine and good technique by heating up both the wire and the pad and then allowing the solder to flow and not getting it stuck to one or the other so you know and lines is there to show off your excellent work I'm not usually one to advocate good tools I mean well okay that's not really true but you can get a lot done with relatively meager tools but getting yourself getting your hands on a good soldering iron will especially when you're new at soldering will make a big difference in your confidence because I struggle with bad – soldering irons for really long time and if you can get your hands on a good one it's true that the the tool quality in the Saturn Aaron category matters for your success as a beginner like the nicer soldering iron it's easier to learn on because it will give you you'll be able to tell that the shortcomings are your own and not the tools yeah and you're like oh is it me or is it just a soldering iron and you don't know yeah and again the another recommendation for that engineering oh one I think that's what it's called the solder sucker because you will make a mistake with soldering but the other nice thing about using that one is that undoing your your mistakes doesn't feel like a punishment it just feels like okay here's the thing I need to do now and I have the tool that makes it easy to do yeah and that mindset is really important as a beginner I know because I teach these grad students who have so much more self-doubt than even kids do because they know so much more about they know so much more about what to doubt about themselves I guess no but but they're so wrapped up in being good at it while they're learning that it is really important to be able to give yourself that success and know that getting the mindset of it not being a big deal to rework or change something just like we fixed your display addressing earlier it's like getting it right is the point and it's never a straight line between it not being done and it being done so it makes me feel it like I feel like that builds your confidence more than just going following a tutorial and having everything work perfectly the first time being able to fix a mistake I think should boost your confidence more because at the end you're like wow no I not only made something cool but I also have the troubleshooting skills to be able to jump into any situation and you know lies it and being able to make a mistake without a ton of friction to it it's like okay I made a mistake oops undo not not the end of the world thank God what is you pieces though the more like spare parts you have it in your lab right the more projects you make and fail at the easier it is to make it fail because you have to rework stuff because you also have more tools experience and resources available to you for fixing the mistakes no yep Mike you were about to ask a question as we've been distracting you with our banter I did notice you've got these ones going in through the back and then you switched to going in through the front I noticed that too at one point and will it will it block the foam core I can't imagine it will I mean I'm just gonna be pressing this into the foam core itself I mean some will be trailing out the back and some would be fit you know coming up from underneath the board but I think it should be fine okay yeah yeah I noticed myself doing that too and well that's that's the thing I changed on Facebook DDOT asked how do you recognize a good one I'm assuming the it's a reference to good solder connection and as Tyler solder it's needs wires I can explain the heating evenly between the pad and the wire will allow the solder to flow evenly and make a good electrical connection to both components and the way I can tell that it's good is that it is bright and shiny and color and round and consistency and looks like it has some surface tension against the wire and the pad if it looks like a big like convex full like like the Russian building with the pull top then you have to worry that it could be could have cooled as it approached that solder pad and not actually made a good electrical connection with it so you're looking for like a smooth concave shape that that swoops between the solder pad and the wire to sort of show that the capillary action of the molten solder and the and the proponents made a nice even spread and I can also tell on this technique of removing solder and leaving the soldering iron for a moment after removing the daughter ensures that that's how it's gonna flow throughout the joint before removing the heat it also makes it also allows you or avoids the problem of you take the soldering iron away and the solder wants to cool pretty quickly and then you have this leftover stick of solder stuck to your joint and great and I'll flip this over the the real aha technique for me was learning to heat use that the tip of the soldering iron to heat the joint both the solder pad and the thing you want to solder to it and then touching your solder to basically the other side of it so you're really using that that you're only relying on the transfer of heat to melt the solder rather than the tip of the soldering iron because it's pretty common that you'll you know tip you know touch the tip of the soldering iron and then touch the solder to that but really all you might be doing is just melting the solder to the soldering iron but not to the joint right and occasionally you can add more solder to enjoy by touching it to the soldering iron tip but that's a kind of only if you've got a hole and flow going already for it to join up with you don't really want to apply solder with the soldering iron no Tyler should also be wearing eye protection while he's clipping these tiny wires but it's not your eyes dear viewer that he's going to hook out it's just might know that last that last snip he made I just watched it go dangerously close no thanks you like if I'm not wearing glasses I will put my kit my other finger on it so that I can ensure that the bit of wire won't come flying while well it's good now one thing I would really like to see if I was being a real stickler for this is I wouldn't love mind seeing the solder flowing all the way through the joint and turning the other side of the solder pad silver these are the gold or copper but I think I've got I mean I've got a good connection through through the wire onto the solder pad okay see you know the stranded wire has bit the capillary action I spilled the solder onto this I can see it a little bit on that site yeah it's just not flowing all the way through and doing the same thing on the other side I'm sure if I just kept feeding soldering it would eventually get that but in the YouTube chat Chris poker has two questions Brian answered one of them does the esp8266 need a companion program running on the network or good as a probe with social media sites directly and it does probe the social media sites directly using the API so that's what the code libraries that Brian wrote are really useful for is creating any Arduino based program that needs to ping the social API for any reason so you can you get just more than just a follower count you can get like the current recent tweets or the the number of people that I follow on Instagram or anything that the API can serve up these Arduino API libraries that Brian wrote will will allow you to access directly from the esp8266 and it said it is connected to your local Wi-Fi network so it basically is its own little thing pinging those API but the other question was is there an update rate what's the update rate and the the API is our rate limited so like you can't ping it our jillion times a second but I can't remember when we get to the code how often the sample code wait a sec to update like maybe once a minute once every five minutes I find I think it is it does feel like it's once a minute or so I feel like the YouTube one that I have going separately is updating more frequently than that because I definitely see it tick up when say like I get a say I did a clever you know I do a collaboration and getting a lot of traffic and my followers are going up more than one a minute I remember like the YouTube one I definitely have going faster but the multi social tracker one I think I had it set to like whatever the most limiting API was yeah and I have all of these being called in the well each one each each social media call has its own function in the code and I'm calling each one in the the main loop of the code so if any of those time limiting things are built into the funk then I mean it'll all be slowed down by the slowest one well I just think it won't if you request it and your rate limited on that API key then it just won't give you the new number yeah oh it just won't update the that one or maybe it would return zero it depends although I did notice because I finally got the code completely running this morning I needed to get for the for the YouTube one you need to get the channel ID which if you have what I'm gonna call the vanity channel name on YouTube which digit key does there's is like just make slash user slice did you hear something like that if you don't have one of those who get a long alphanumeric string that's your your channel ID and that's what you actually need to put into this code and I just got digit keys channel ID this morning so I can plug it in I was doing that look it up for you I was doing that in our weekly editorial meeting and I noticed as I was writing the code and looking at they games well I tested I'd be like I unsubscribe for their from their channel to see the number change and then subscribe again and then as I made was going on they gained two more subscribers that's great motivational I keep laying up on the wall and like it's true that when you measure things they tend to improve and well I'm not like I'm not hung up I wouldn't say I'm hung up on my social media fame it's definitely a tool to visualize the impacts that you have and then the community that you have chickens we also like make things alone in our workshops a lot so to have the idea that like visual reminder that of how many other people are out there like who want to participate in whatever you're working on in your workshop is kind of a cool uplifting reminder but it's also completely under watch that take that because like it hardly ever takes down oh that would be bad yeah except for that Twitter bot clear out but that happened like overnight you know yeah then you just wake up the next morning you're like wait word all right yeah but I mean when you watch it tick like it usually ticking up so that's yeah nice yeah I got one more Instructables fall over since we started the broadcast all right got those all punched in laughs no Dave is pointing out that if you pretend those wires they might be easier to put through the holes oh did you fire if you put too much solder on them then they become too fat to go through the holes that is usually my experience with pre tinning and it was usually why I don't it's a matter of preference if you if you can go kind of meter on the solder application it's possible and I've done that before with really really fine stranded wire but that the stranded wire using doesn't look like the most stringent in the world no this is yeah this is a I think it's like 22 gauge stranded wire so if I get if I get any tinning on there it is gonna bulk up really fast so just to recap what have we done so far we have assigned the six seven segment displays to the various addresses so that each set of two represents a big digit number for each social network so three numbers for three social networks six seven segment displays so we already did the addressing and now you're soldering all data and power connections yep and then the next part after this well I'm going to lay everything out into the into the foam core and hopefully I've got everything I'm not gonna glue anything down just yet because there's no guarantee that I have everything laid out correctly but after that then I need to basically seek or chain all of these together so they're all in the same circuit and wire them to the board and I've actually already got the code on bored so then I'll just fire it up and see if it starts to display stuff that's good Brian was concerned earlier that you were gonna have that wanted to remind you which version of the library she should be using in case he needed to go to bed so now Brian you know Tyler as well said um the code I know works yeah I've been I like I said I had it running this morning in the in the serial monitor and everything was displaying correctly okay so now it's really just making sure that it's working the displays okay what kind of saris in there what's up what a kind of Clippers are you using these are the hakko ones which are always surprised me when I buy them because I my experience with Jaco is that that's the good expensive stuff but these are stupid cheap on on Amazon I think they're like three bucks apiece and they're they're really important to get because you can get relatively you know because the cutter so I'm going to show it here on camera the I mean these are what what is referred to as flush cutters where the blade is actually right here so you can get right up next to the PCB almost to the point where you're almost afraid of scraping bits off of the PCB and get a really nice flush cut a relatively smooth cut which is what I'm trying to get here okay so that's the last one of these together and now I've got to make all these connections remember the order that these go in so one is here on the left two is on the right I'm just gonna press these into place and then hold it up and you can see what this rat's nest I'm about to eat daisy chain together is going to look like that's – in there this is gonna be kind of heavy when it's done those wires clear the way did you keep up a known MCU well talk soon I'm assuming yes but did you get your known MCU from digi-key yes I've got everything that's news to me that they carry those Oh I remember when they discontinued the digi-key catalog is big news how do they have like a big physical catalog yeah famously big bigger than mcmaster-carr Oh much bigger like twice the McMaster catalog okay so that's what we're looking at now hey and here's what it looks like from the back Oh looks even better on the back and now I've got to take all these connections and wire them together green to green yellow yellow red red black black yep my life a little bit easier if with regards to that well then I've got to think about how I want to do this so that everything is going to be laid out well this is where I wish I had a nice top-down camera but I don't we'll make do I know I have yet to find like and they just you know the optics of macros such that you can't have a nice Flint let's assume and both a really cherry macro and medium frame it would be our dream wouldn't it yeah alright so basically what I'm doing is I'm just kind of chaining these together and then I'm going to here's what I really need to think about is I've got the top row red wires chained together but then I need to connect them to the middle row and then the bottom row so maybe I can just use this they can all go together in one into one foreign ones okay yeah maybe that's what I should be doing but in which case that makes it a little bit easier well here it's gonna be six into one oh right sorry mine's four into one yours is 6 into one mine's an extranet Maris yeah but you'll see what you should do is solder them to another wire and then use that wire to connect to the node MCU so that you're not crowding the pins yeah yeah I was gonna make sleech Ain them all gang them together all into one let me in fact this is actually a place where I can bring the macro in and show you what I'm trying to accomplish here and then pull a single wire off of that momentum will go into the microcontroller board without any space problems yeah so that's my gang of so far three connections you might need to trim some more insulation just to give you enough wire to twist as that fattens up yeah that might be good I love going over suspension bridges and looking at their giant cables cos reminds me a stranded wire but it's bigger or like vice versa or like when I'm twisting together stranded wire like that it reminds me in bridge right yeah yeah maybe knocking this you know getting a little bit more strand here is the right call a little more strand for your buck my car you host helping to host the live stream at Maker Faire next week I will be taking some turns on the live stream yeah that's a lot of fun you know it's I actually find it to be one of the one of the cooler ways to experience Maker Faire because you kind of get you know you well you get to but in front of everyone that is for the official live stream coming through and like out of the line right in the back of a crowd of people waiting for your turn to see a booth right and then you also you know you can you can you kind of have to run through things you know you keep it moving keep it moving so you it's I actually find that I knock out a lot of the exhibits a lot more doing the live stream than I do just regularly because I kind of have to right because imagining it for another audience to in here your rating for them so you get to so the end result is that you have a lot of people to maybe follow up with afterwards for a longer conversation but you get through a lot more material okay so there's my solder nightmare it looks great put it here in con it nobody'll know yeah I mean my biggest concern now is just making sure that I can get enough heat in there that I can get everything connected nicely that's we're having a nice time and it comes in handy too because the when you talk about having a nice soldering iron really the important part that is nice is the power supply writing I want it to be able to deliver a lot of heat quickly and not and be able to compensate for a loss of heat quickly and so if you're attaching touching it to that big thermal mass it's gonna dip the temperature of the soldering iron pretty dramatically and you have to have a soldering irons power supply that can keep up with that demand in order to keep the heat coming and not if you look at like the graph of the temperature should be as consistent as possible so like the tip being dirty is one thing but if you have a how much plan I can't bring the heat I'm never gonna get a good performance out of it speaking of dirty tips that's pretty well explained thanks Becky so my friend see on the unexpected maker has joined us in the chat Pelosi on from mercy from Australia what time is it there all right so yeah I'm starting to get enough heat into this joy that I can just and then man crafting I subscribed to man crafting on YouTube hello that is type fingers yep soldering the wires yeah hello Chad Chad is man Chad is Chad for man crafting from man crafting we've never met that's my understanding I met him at Maker Faire New York last year okay I've seen because he's looting it being one week from now that he's coming 11 a.m. in Australia good morning Wow but tomorrow yeah I know he's he's talking to us from the future all right I think that's good so watching this as we as we twist this and and solder it together I've got a question for you guys as more of electronics experts than I am it's it looks like when I work on a lamp project in my house and you know if I'm doing some home renovation something and I use those the twice lock wire or wire nuts yeah why not use those for something like this that's my question um you certainly could i I don't know that wire nuts hurt I don't know what it why nots always weird me out it does it always feels like especially for high voltage connections which is what you usually use them for Thanks voltage because the it's the connections not they're insulating first of all so in that way they actually like a heat a heat shrink tubing or a electro tape but they have a conductor inside them so they're helping to make the connection besides just holding that wire together but the curve I always considered them good for something that was gonna be inside a wall and no one was ever gonna flex the connection because if you flex a connection it can come undone but for high-voltage stuff say that the wires are dirty the high voltage is going to be able to bridge the less than perfect connection more easily when we're talking about house current we're talking about one 110 volts is gonna be able to bridge over a somewhat occupies connection more easily than a low like a direct current low current I'm sorry direct current low voltage situation so I would say you wouldn't want to use them because they're not as electrically connected as solder and the reason that and soldering is used in house wiring my grandpa my uncle actually electricians and that high voltage Miss of house wiring can help make wire nuts a feasible solution but they're all so clunky and big so the reason people don't use them for electronics small electronics projects it's just because they get in the way and there's more we're all driving towards small and so soldering is a way to make your circuits a little more tiny and compact but it's true is there is no reason you couldn't use wire nuts for a project like this just I would recommend then keeping all the wires like inside a case inside the back of that thing so that they're never being push it around yeah because it will cause why are your nuts to comb disconnect it yeah generally with wire nuts you once you have everything wired up you've shoved the whole thing in the junction box and assuming that you haven't told anything loose through that it shouldn't go anywhere exactly good tips but also the wires are dirty it doesn't matter as much because 110 volts it's gonna create an electrical arc between a lot more dirt than quite a bold signal okay so now we've got our connection for ground and yeah stripping off a bit more and then twisting them all together made that look a little bit tight here don't forget to switch you can see that there it is maybe this will even solder together a little bit easier and they'll soon and of course once this is done that I'm going to get some heat heat shrink on all this although I think somewhere larger diameter heat shrink is clear so don't get to hide as many sins as I would like what sins your solder joints are perfectly fine I mean it if anything is just your strategy that looks a little clunky right but it's fine to have all these wires into one yeah much less funny than trying to solder that giant twisted thing onto the pins of your microcontroller what kind of soldering iron are you using um this is well I was recommended it's a tough one to recommend although it is one I like a lot because I say it's tough to recommend because it is the RadioShack digital soldering station Oh tough trick maybe because you can't get it yeah you know we had a bunch of these from when we had a a marketing deal with RadioShack and we had a couple of these kicking around yet the neat thing about it if you do some research is its I mean RadioShack did not make this soldering iron of course takes a white label you see you can find it somewhere yeah it's a German brand I know that yeah and it's a 60-watt digital soldering station and it works pretty nicely I like it a lot obviously people like to recommend the the hakko digital soldering station well it makes a really nice one yeah my first soldering station as the Weller that's great yeah hot code now where's your third hand tool that's what I want to know Forex otter joint like this ah my third hand is right off camera here but these are I mean I'm dealing with wire stiffness enough that's kind of like staying in place so I'm not too worried about it sometimes I find that I'm able to apply more pressure and a big solder joint like that you really want to keep that Saturday and I are touching the joint consistent and sometimes I'm not able to put as much pressure anywhere to make that happen unless the the John's are holding it really close I will try that with this yellow wire which is my I squared C o'clock connection and we'll see see where that gets us that's two now this is starting to turn into a bit of a rat's nest this is so different from how I should probably get back off of that I'd originally envisioned like doing some fancy layout with this where I really wanted this thing to look exactly like almost like a frigging diagram of the wiring mmm this is this is not that I sort of ran out of time with that design phase it could be Fritzing doesn't have to look tidy either the ligand rust lines from connection points but can you can you do for the one I think you can as long as you like drag everything to a node point and then say here you go everything that comes in here base that's true in Tinkercad circuit sir you can't terminate a wire in space has to be on a node would you get overlap wires to make them look like they're all going into one at a point further upstream than they actually are yeah all right gang all these together and Becky you've mentioned a couple times that you you teach some classes at SVA you want to tell everyone about what is SP a pool of visual arts is an art school here in New York City which offers all kinds of undergraduate and graduate programs and I went to I went to a rival school for undergrad here in the air called Parsons School of Design but the program that I teach it and called products of design itself either products of design tied sdd find more about it it's a grant product design program and it's relatively new this will be my sixth year teaching in the program and a inaugural faculty or a founding felt like the I started teaching there at the program's inception with part of the programs like creation and so it's only 60 at five years old and it's like 20 it's a two-year program and there's about 20 students in each year so there's like 40 students total and a lot of adjunct faculty in teaching I mean I'm like the most one of the most technical classes there is that a lot of like design strategies and teaching people to be like responsible future product designers who can now you know make physical prototypes of their product ideas with real electronics components and even if they have to have like an Arduino board off to the side and wires running into their prototype for size constraints there's a lot of power in enabling designers to be able to visualize their ideas and really understand the that bridge between like physical worlds and digital world stuff when it comes to like designing physical objects or designing experiences it's super useful so I'm jealous of all astute stuff my students need to do and their program I get to go in all kinds of crazy field trips to special places that people don't usually get access to and study with some really awesome high-profile folks myself went with standing and it's a good yeah it's awesome it's a really fun experience for me really fun to see what the students gonna do after they graduate you now that there are a couple of classes that have gone through the program that's really cool yeah well nice alright one more connection made and green left right just green slowly getting there actually the other camera here well I'm doing this wiring that's I mean you say it looks like a rat's nest but in reality if you had to do this project without those I squared C matrix back crack's oh it wouldn't be and what's crazier than a rat's nest like a beaver dam I don't know and it really would be crazy if you had to control each one of the LEDs at the sensing windows like separately so we're getting a lot by using that I don't remember the number the max chip on the back of that seven segments back crack so like now you know back in my day you're gonna walk school uphill both ways in the snow barefoot and with no ice crazy backpacks yep all you had to do your multiplexing all yourself yeah exactly all right so there's me I've like made of multiplexing LED circuit one time it was like 15 years ago get all these green wires together it's for them and remain crafting is asking if didn't I make a social media counter that is why I am on the show today so that I can teach I want Tyler through the build of my social media stats tracker counter display didn't you make yes it's on YouTube and it's on Instructables so if you if you find the project I don't know if there's a description for that yes there's a description for the video and it does not have a link to the project in it I can't put a link in the chat but I can ask Mike to put do it in the description of the video so that you can find your way to the tutorial if you would like to follow along and build one of these yourself and it will Clorox wipes asks that's not your real name the one your mom gave you does it does it recruit why YouTube subscribers – and the answer is yes the title building it goes hybrid design right – so the status tracker that the project tutorial is for is the one I built this for Twitter Instagram and Instructables polymers but it's based off of a previous protege mate that's just YouTube subscribers so Tyler is combining the code for the two projects to swap out one of the networks for the Youtube subscriber count but it's pretty easy if you look at the social status check or tutorial it's pretty easy to see how any of the two tutorials it's pretty easy to see how do you glued them it's just like a separate line of code to call the instructables API instead of the here's the yeah called the YouTube API it's sort of the instructor with the API so you can kind of mix and match to your own preferences and I bet there's a Facebook game pi2 that we haven't talked about and neither of these projects directly reference it but there is another you can use to grab your Facebook followers – that's a network gets written to you yeah there's there is one gotcha I ran into when combining the two pieces of code which is that there is a variable that you uses that gets passed into the libraries that the Brian wrote and in the YouTube one you well there's two flavors of them that you see two flavors that variable that you see so the the multi strat tracker that's called like a client and clients secure and in just the YouTube one it just needs it needs to secure one but the variables has called like client oh yeah you care wasn't working at first although it wasn't giving me any descriptive errors and then I just said oh here it's called you know I noticed anyhow that was just one thing I just changed when he must have updated the some libraries to work on less secure connection and then maybe others didn't need it and I don't know could be a library update my snacks problem also where like he updated one librarian not necessarily all of them that's cool okay pro tip I would love it if you would share your new your new code sketch I I should probably do that yeah and when we get into the code I can take a look at that and because I'm remembering that that catch from memory which is always a really good technical tip it's like I remembered this from like this code I bought together last week I'm sure it's really fresh in my memory yeah right and well but sometimes when some things first you can't forget it yeah I mean you know you have that aha moment with it and you know that kind of cements it in your memory pretty well but still great and a lot of time yeah it's a lot of time limit I remember like I was having an adobe premiere problem like a summer camp job in college as a summer camp I liked ruminated on it I couldn't figure out what the issue was and and like I actually had a nightmare and ended up walking in my sleep and I figured out the problem while I was like walking in my sleep oh wow messed up but I woke up and had the answer it was weird it was like exporting the selection versus the whole sequence problem I was exporting the select the sequence and the sequence was set to shorter than the whole project hmm yeah it took uh stressful night of sleepwalking to figure it out I guess I only sleep when I'm really stressed out Andy right wants to know what the link is to the code Mike are you putting a link to the project tutorial in the description I am working on that right now I can't put it into the chat but I could do it somewhere else let's see if I just tried putting it in the chat see five okay put it in the chat I know that yeah great okay thanks yeah Mike just put the link to the tutorial in the chats and you can find it there and then in that tutorial there's also a link to the YouTube display that I made right in the first paragraph so you'll be able to find both of the posts that Tyler is using for his thanks perfect and I'll try to update the description itself to put that embed it right in the description I'm gonna be careful about doing it right now because I don't want to click the wrong garden and yeah all right so Hank treat heat shrink tubing on our data connection next we'll do the yellow which is our clock and we are running a little bit short on time so I'm gonna well how do I want to do this with the actual note MCU board maybe I should be smart and solder these onto some female headers so I can just plug them onto the board let's do that let's take a lazy you have the assembled one right yeah the one I have has the headers already soldered on otherwise had decided this straight on the board but I also want to figure out a way to like display the note MCU yeah okay check it out but then like do I want to power it from the back so that I don't have like a USB cord hanging out the front I think these are decisions that I'll make off-camera of how I want it yeah how do I look stick it yeah we're gonna make it look we're gonna make it work on this and then we're gonna make it I'll make it look pretty and that way that people can see it if they come to New York which they should or they or they check you out on the livestream or that maybe you'll post a picture of it on social media yeah I'll do one or many of these things and so somebody who's asking about the cost of the build materials for this project and the version that I was making hats bigger displays than than the version I made so those displays are are more expensive although but I'm trying to remember I want to say that this displays I'm using they're like 20 bucks apiece and I have six of them so 17 II the 1750 times six it's just in this place and the noticing you word and that's basically your total cost of parts right there yeah and then mine is the smaller ones that are listed see I'm gonna say they're like $8 for the backpack and yeah other 995 yeah so and mine since I don't have not making I only used for seven segment displays in mind because only only one of my social media networks had over 10,000 followers in the display that I made so if you have fewer than 10,000 on any of those networks you can get away with just one of the segments look seven segment displays because there they have four digits each so it's so for if you only have one per and they're $10 the next 30 and then the dope the not I'm Singh use what like 5 it's like 35 bucks yeah I think I I know I always end up getting these in the two packs which are like 12 bucks or something like that for the two of them so so it's very lacrosse this variable but we're looking at a minute minimum of about 35 event and upwards from there not bad no not too bad did this reposition and focused before I hit it with the heat gun I like the sound of your ikan heat shrink tubing is one of those oddly satisfying procedures a little bit of calm in your project struggle all right this was where I'm gonna make myself a little crazy because I have these female headers close to hand but they're nowhere near the colors that I'm actually working with here that's because you're just gonna make little shorties you'll still be able to see the wire color when you yeah forgive you don't recommend this but well actually no I have green at least I can match green okay we'll pretend it's worse if you if you have the same colors and you mismatched them than if you just use different colors yeah there is red in purple so we'll match purple to red and you can do white foreground I happen to like white and black are both Brown that's that's a habit that I sometimes still do because then the very first like Arduino kit I ever got had no black jumper wires so white was a white was ground that's just how it went conventional electrician talk weight is usually the hot wire weight hot yeah but that's electricians it's true I am red red is hot and so when I'm out it when I'm out of the proper color wires I use like the same color color temperature so it's like oh I don't know Fred tell use orange or like a doughnut blue so I'll use purple or green something like a warm color and a cool color for power because I learned color before I learned electronics if you don't know what a warm color is in a cool colors that doesn't help you and then trying to have that discussion between an artist and a scientist I was trying to explain to my students yesterday that like the color of the wire does not have an impact on its ability to conduct electricity it's just the color of the insulation it will have an impact on your ability to understand the circuit once you build it built it but that it like that I mean that's like it's a valid question right like just the wire color matter I see allotted four wires up there like I have a bunch of different color wires if you if you're in the point where you don't know anything and it's not a question it's sure cuz you know resistors that are different colors aren't electrically equivalent no and I mean maybe that there are LEDs for that matter I mean obviously the it's the wire gauge that really matters its ability to conduct well or not but that's more I mean you imagine how much easier would be if you could just look at where go oh that's red I can put you know 50 amps through that which some kinds of connectors are a little bit like that where like the Spade connectors you know those are color-coded for their wire gauge and I think also because they're wire gauge they're how much they can conduct also factors in there mm-hmm and also what crimping tool you should use for them okay so this is ground green I'd go with our old tradition of white as ground tell her you're gonna heat shrink these as well I'm assuming yeah do you want me to prep some little short pieces of heat shrink while you're doing that um yeah we've got this blue stuff here that I mean I'm perfect that should still fit over the end of that the header it does good just be right I've done a correct thing what are your favorite YouTube channels you folks are watching I'm curious about you to Tyler and Mike but also anybody in the chat you have any cool channel so you've been really liking lately I can use some new channels to watch um I don't know that I have that many new ones that have been following well ones that you like that you think I haven't heard of yet I don't even know that I I mean there's a lot of favorites that I keep coming back to over and over again they're kind of my youtube comfort food I mean every Laura comp video is always great I was seeking it yeah I was enjoy machining stuff from this old Tony his stuff is really great I know these are like thick people I just I like to watch because I enjoyed like their their presentation and just how they how they present their ideas cactus workshop this one I really like I love his like kind of punk rock aesthetic to the way he approached his videos yeah I group him and Jack oh whatever together in my mind sometimes it chokes up their act I'm not sure if either of them would be offended by that I mean I love Jacko's channel 2 but this stuff is always so polished whereas like I don't know the cactus workshop is more like hey let's bash some stuff together and make a skateboard fidget spinner kind of thing and more of it well he made a back wouldn't fidget everybody was making fidget spinners he made a huge one that was like this wide he the bearing in it is from like some he he has some junkyard near him and he just found this industrial bearing then the two counterweights on either side were just like big formed pieces of concrete let's see I haven't checked it I haven't checked in on her in a little bit and I'm hoping she's going to be at New York is a maker called Junie genius I think I'm doing yellow to blue because that doesn't make any sense at all other than I already I have green and green we'll go with green yeah she does a lot of comedy with like she builds insane contraptions that don't work well I hate to draw the immediate comparison to somebody like Simone yet because that's really unfair but yeah she she makes neat cool things and utterly wild presentation style that I can I can never look away from what's her name again Junie genius Ju and ie and it subscribed nice yeah I got all those other ones already yeah I need to I need to dig in there and find some some cool new stuff to recommend there's a few coming in on the on the chat here as well Bryan Ashman recommends the Great Scott Channel oh yes Great Scott good good stuff for electronics mm-hmm Orpheus Ramos is recommending Ivan Miranda or Ivana Miranda's 3d printing electronics he's a 3d printing electronics guy from Spain yeah man crafting is recommending Fowler's maker Ian mischief I don't recall out the chuck name like how big her channel is or not but I know that I learned about it from working with Donald on Maker update now that we've been doing that but barb Noren from barb makes things he's one of my favorites yeah she's fantastic good tips good projects use of my time I struggle with these longer like videos I don't know if you've noticed this Tyler doing videos for many years and they've gotten longer they really have them at like 2:00 and I'm half three minutes was the most you could get someone to watch and now like I'm seeing maker videos at like 15 minutes long and they're great but I can't I can't be a fan of like 15 different cool makers if they're all gonna publish 15 minute videos every week yeah I mean I would really I still need to set aside the time to sit down and watch Loras one day build with Adam that ridiculous oh I skimmed around I couldn't cuz it's just too long like come on guys make a teaser for it yeah in fact the only one of those like one of Adam's videos that I ever watched that was that long and I watch the whole thing and it's funny that this is the one I pick but also it's a really good one I think everybody should try and watch at some point it's it's when he was machining a bunch of fittings for like a spacesuit replica he's working on and it was it was a bad day of machining for him like nothing worked and the reason why I say it's good for everybody to watch this first to watch it you know watch Adam Savage having a bad day of the shop it makes you feel a little bit better about your day your bad days in the shop because everybody has them and they suck and they will steal your confidence and make you feel like you have no business doing this but then you watch somebody like Adam Savage doing that and kind of talking through the process of like how he's going to approach in the future and like one he needs to walk away from it for the day I think these are good things to reinforce it's like it's be bad totally it's also okay to edit your mistakes into a three minute long video yep mark we were talking about barb and how her videos have such a nice concise she talked about failing she talks about trying things for the first time as a kid and now take like kids have lower grip strength and so designing projects for that it's a little bit different and and she never goes over like six minutes yeah I tried it and then of course I also watched lauren Simone's latest collaboration which is uh the tampon dispensing upon PEZ dispenser now it's also grateful it's like oh I this is only ten minutes I can I can watch this before I'm even getting out of bed this morning yeah right I went I made a TV be gone bring both of those things to a restaurant and that's where I was using the TV be gone post so it seemed logical to me yeah alright so fingers crossed we are perilously close perilously close to maybe utter disappointment on the precipice and social media stand counting although really thank you I'm watching the stream like you know I can't see my view doesn't show your hand so I watched the street and the stream is like a few seconds to leave all right here moving is extremely satisfying oh good it's smaller maybe that's the Boca the next next sensational youtube channel or Instagram channel heat shrink tubing shrinking at Paolo that watching the heat shrink around various shapes well your your heat your tool the blower a heat gun has a bit of an ASMR thing about it nice have you guys seen the the the laser rust removal channels people oh oh my god that's that that that's a one of those instant addiction channels it's just rusty things being cleaned with high-powered lasers and they've make devices specifically to do that and it is absolutely captivating oh yeah now I'm wondering if anybody has attempted to combine ASMR and making now that I know of yet yes although we've said it so I mean I've thought about it but I just I don't need people fetishizing me any more than they already do honestly yeah yeah that that's a thing objectification always happens when you're the minority in a group right and yeah highlighting it is it you have to like lean way into it or lean way out of it alright so now I am starting to connect things to this board here I'm guessing because we want to get the 5 volt or when I plug it into the in and ground is right next to it and then I probably need to look up to figure out what pins SCL and SDA are on for you what do you think I am here for idle entertainment I've got a circuit diagram right in front of me it's um they pull this up on the ones the like closest to the antenna on the non power ground connection side the numbers are just really small and the numbers on the board don't don't really necessarily to the numbers that you use in code either that's a frustrating thing about the note and see you with the silkscreen numbers are a little arbitrary alright so there's our board that we're looking at here I'm sorry you said so I've got green as data and that goes where the third pin from the bottom on the opposite side from the power and ground connections d2 I think it is I can't read the number it's too small – okay and then the yellow one goes to d1 if you use the same wiring for yellow and green and it's my circuit diagram did which I pretty sure you did um that's a great question if not you can switch them it's not gonna hurt it to get it backwards yeah okay um so that could be wired up correctly reading to D to yellow to d1 green to D to yellow to d1 yes that's that's it and now I should probably turn my soldering iron off because I'm confident did you turn it up well I mean that's the other nice thing about this soldering irons it heats up pretty quickly I had a USB micro connection so now that I'm looking at it again and if you're going into bi n that's supposed to be the voltage that's coming in from the USB port so maybe it's not that's not going through the voltage regulator and they just put me pulling the five volts from the usb in the USB and that means that if it's drawing significantly more power than mine you just won't be able to power it from your laptop you'll have to plug it into like a 2 amp USB power brick or something I may need to find one of those but like you said the numbers that's it all the numbers are on at once so I thought you're a problem firing it up but I just thought of it as a concern for increasing the size of the panel does increase potentially increases your power consumption this is a moment of truth um well I am now pulling up the Arduino IDE because I don't have any I just plugged in power to the board and I'm not seeing any lights or anything but then I can't remember if this has any lights that should be displaying at the moment so I'm gonna pull up the IDE and see if it's powered on I see the serial monitor if it does I'll pull that up and then we could take a look at that for a moment hmm I don't have anything on that serial monitor that could be a worry did you print it press the reset button while it's plugged in because it won't if it's gone through its first light request cycle it'll wait till the next cycle before it's that's anything out okay I haven't done that that was a good tip and now let's take a look hey it's getting so it's connected it's alive its alive now the thing I haven't done is flip this thing over to see if we're seeing anything on I can come back to the main camera here and I can do the reveal for the camera not necessarily for me and let's see what we're looking at here although I have a monitor for me cuz I can see it oh nothing that's nothing and I think it why is there nothing lots of reason could be yeah I guess the first thing to check is voltage do I have some yeah you have a multimeter handy we do have double check that your clock and data are gonna are indeed the same as I told you the same as my tutorial that I was reading from me like you know that were in accordance cuz we did you some I suppose I could and swapping up there I'm just gonna check a couple different displays here ah that's reports four points hmm Green is data for Pongal it explodes I wonder how tall are these are of being under volted somewhat maybe not the white one or the blue one but the red one certainly yeah because these are red yellow and green and your data line is your green connected to d2 and your yeah and let me double check let me double check the code here as well to make sure that that's what it ought to be well it doesn't say in your code the pin oh yeah it does say pin yeah d1 and d2 well it'll say in the code and I'll say the arduino or sorry the I'll look to what I mean to say I also need to double-check and make sure that all my addressing is correct although I should be at least see something yeah exactly you would see you would see numbers and they would just be in the wrong place if you're addressing because you have so many addresses that language show up well let's do it we had two that I'm also looking at the wrong code here I mean this is just the YouTube one I need to open recent and go to our digit key social tracker display this is this is the real code all right you don't just you don't um describe the pins in the code because they're the only ice currency pins on the esp8266 so it assumes those pins that makes sense I remember that confusing me at first like where do I set the pins because that's really normal to want to make sure your pins are addressed right but it's all in that I squared C addressing and you just have to make sure that data is to d2 and clock is d1 and that your power supply is beefy enough I guess right maybe that's when I'm running up against here is that no different I would check the wiring accuracy first yeah I definitely have like yellow is clock and that's in d1 and green data a greenest data and that is going into d2 so assuming the silk screen is accurate yeah then this should be good there and otherwise I think that's the next step is to find a beefier power supply yeah I mean what do you have it put did you know I have a plugged into my MacBook Pro keyboard hmm so that's probably not doing what we call deliver like 500 milliamps through the USB port what is this guy here but it would theoretically be like we started you'd see I think you would see some symptoms of under power besides it's just not working that's mine cut like you would get constantly restarting because it would try to draw power and then it would reset yeah well let's see because I have a 2.4 amp supply here that should be beefy enough we'll want to hit that reset button then the other question the other thing you could try is to just use the reload it with the I script C matrix backpack sample code yeah justice just to make sure that it's not something else and of course now we do the serial monitor anymore so we're just gonna have to wait for it to connect and then hopefully display something cool on these numbers look never happens for live demo it's like it does it to fight you I totally would have gone okay do you have the you have learn the arduino ide up right can you pull up these simple matrix backpack code yeah it's in for those of you watching at home you can get to the any library it comes with sample code you just go to file examples and then find the name of the library in this case it's what a to put LED backpack library yep and then it it e7 sag it's the name of the sample code that will work with those those backpacks yep what's and and you'll only be testing one of them and that way it'll consume even less power and it'll just light up one and that'll just verify that your bus is effectively working your i squid sea bus LED backpack and yeah seven sag that's what I write whatever I am starting a new project they usually start out with a sample code for each individual element I'm adding and just to make sure that I've got my wiring right because the sample code is guaranteed to be working hopefully anyway and then you can you use it like we can determine whether or not it's us or the wire connections because if it doesn't work with the sample code then it's probably a physical problem right first software problem yeah and it's uploading now and that seems like a physical problem alright cuz you're not getting anything right not seeing anything you bought it one from my you yeah no yeah yeah lift it up a little bit higher so that oh the banner doesn't block it there okay then when it's not on we want to be checking continuity now right you uh like power it down and then check use your multimeter you check continuity between all of the wire connections that you made yeah if you ever order it somewhere less short between data and and clock that could cause what's happening right now yeah let's see yeah you probably done in a short with power because you measured the voltage already where did you measure the voltage at the back of the I wasn't that careful I was just jumping between the power ground on the board itself not like power and work yeah okay I mean it no I'm sorry the the like checking voltage between the backpack and the ground pin on the backpack right yes that's but but we want you to check continuity while the circuit is off between the between data and clocks make sure there's no connection and then between each between the pin on the microcontroller board and each of the backpack pads for both clock and data does that make sense yeah the continuity you have to test all the circuits powered down all right I'm not sure if this is necessary to check continuity for all the voltage connections but let's do that well the mainly concerned that you can have a short between data and clock in data or clocking it's something else yeah I want to make sure you don't have continuity between any of the four connections that shouldn't be connected to each other and then and make sure that you do have a good solid connection between clock on the microcontroller and clock on the backpack so Becky would the fastest way for making sure we don't have any continuity between well that's that's a worry cuz I'm right now I don't have continuity from oh that's the wrong pen if you that's where your check of you don't have continuity is just to check the continuity at if it doesn't beep then you don't have a caption okay there it is that's that's the continuity I'm looking for so it can be used as a positive test and a negative tech that's yeah you don't have a short end that you do have good because you know some of those bigger solder connections you made maybe the solder doesn't go all the way through that could be a thing that was a worry and it looks good when you did it but that doesn't mean it's not worth double-checking or at least mentioning to our audience that that's a thing to try or to the thing to check for with the multimeter right okay so far good continuity between data and it's not being bridged to clock and let's do the opposite check round or power well it didn't check for ground or power yeah make sure it's also not shorted to power around also not great and if one of these is shorted would it affect the entire display or would it just it would it would do and do all of it the data and clack connections they have to have they have to be able to move stuff signal freely along them right and if you connect one to power ground the like a ground connection would just stop the signal straight to ground because power troubles on the path of least resistance towards ground and then if you had it shorted to power it would just be like trying to have a conversation while the fire alarm is on cuz there would just be power flooding the bus and then an individual signal would not be able to like get through so that make sense yeah yeah yep okay huh well these connections seem good I'm wondering what else to check what about merge numbers is trying to help and asks if we have a common ground but I do believe that that's what we just checked for and common ground is happening I mean we can I have a check for continuity for ground yet but we can certainly do that well you checked em you checked voltage while it was on which effectively check continuity on all of the power and ground but if you were getting of voltage a positive voltage rating when it was on that means that it's it's connected to power and ground yeah yep ground all sounds good what about is it is there a chance we have the the data pins plugged in to the end of the data wire the clock wire into the wrong pins it's possible we double checked it twice that doesn't that does not negate the possibility that it could still be backwards yeah so barring another thing to try that wouldn't hurt to try I mean this is just we're googling node MCU you just swap the paint the yellow and green wires on your note of C you board it would satisfy my curiosity but even though we double check it three times they still could possibly be backwards yeah well it doesn't hurt to try right and I just keep thinking about those silk-screening being maybe screening is fine it's just a matter of like us keeping where's the where's the error likely to be usually dead cat right problem exists this main keyboard and chair yeah that's more likely than the silk screen being wrong hold this up and and be optimistic let's go but being optimistic like it gets you really far in electronics except for this the last little troubleshooting bit being optimistic will not make your circuit work when it's broken no I just don't understand how it's broken well if I were doing this project over again I would recommend you get one seven segment display working before you add more because of the possibility of like the complexity getting larger as the before you like you want to have incremental success and in that way you'd be like oh well I know one is working so when I added more and it stopped working like I know that the problem exists somewhere in that assembly process where right now and all six of them are connected and we can't get any of them on my next suggestion is to like do you have a spare one or can you disconnect one and like go back to just try to get one display to light up the one without any alterations to the I squared seat budget edits on the back yeah unfortunately I don't have that I don't have any experience of this but you do can you identify which one is the one with no alterations to the I script C bus because that's the one that the sample code wants to talk to ya that's this upper that's this one here on your yeah the one I'm indicating with my finger here low digits at the top one yeah that means and so like that's the one that I probe at more now Pro but like if you're testing continuity and stuff make that the one that you test although I'm sure you've tested them already yeah yeah cuz here we're looking at although I think now we actually have our data stuff reversed but that doesn't matter for continuity although I probably shouldn't be checking the continuity here with the Ciroc okay you just won't get an accurate reading yeah then let's not do that that's power and ground hmm and you're touching the actual pad yeah and as much as you can right so that you're actually testing the strength of your solder connections and not just measuring the wire in between this higher connections yeah I'm trying to you know jam it into the the solder pad there huh okay and when you power it up that one is that the one you tested for voltage already yeah I mean again that's the only other thing I can think of is well let's check voltage from the solder pad all the way back to the board the ground yeah or just for fun somebody in the chat asking where the API endpoint is where the API endpoint is but it's it's uh what does the endpoint refer to the JSON that you get back when you request the when you make the request I'm not sure what they means that endpoint I've only heard that term mentioned the but the library code logs in as you like you put your Twitter API key in the Arduino sketch and then it requests the data and you gets the Jace the Arduino library parses a json and then it returns from the api request and in instagrams case it's not a true api it's more of a more informal web service well that's a solid five volts across all of these displays tracing out all the way back to the ground pin on the board do do you have and different arduino you can test with this with these guys you mean like a different node asking you yeah cuz I'm thinking of you know when you're troubleshooting you're trying to isolate and different variables and solar disappear off camera for a second here to go grab another one but yeah BRB oh and he met the URL of API to be requested well it's different for each service so this project combines Twitter Instagram my original C's Instructables Tyler's is using YouTube so the you are the address that it sends the API requests to is different for each of the services and it's in the Arduino API libraries that Brian wrote that are used all of them that are used in this project and also in the Facebook flop summer is highlighting a troubleshooting idea that we did already try that you check to make sure that you don't have green to ground or yellow to brown we did check that to make sure there's no continuity between data clock and each other or power right Brown yeah that I feel pretty good about all right handy right really wants to know about the Facebook API we neither of us are using the Facebook web channel is one of our social channels for this project but Brian did write a Arduino Facebook API library that you could use in a similar way once you get the space code working you'll see how obvious it is to swap out something for Facebook but neither of us have done it ourselves yeah Becky can you remind me yellow is clock is d1 yellow is clock is d1 okay correct this is our fresh new note MCU and I played in to the computer and send the code to it and hopefully this will give us something good and this is still the the we're gonna go with the display or this or the the sample code maybe we should go with the sample code well the sample coding serial output which would be useful for you to notice that your know that C U is actually trying to display a current number and then you know the next thing will be all like I would like to take a look at your code and walk through it but after we if it doesn't work on the regular sketch and it doesn't work on the test pitch doesn't work on the test sketch then like it's it could be possible that you soldered your backpack so much again uh-oh Tyler did you shatter your backpack so no chicken uh I matched them to the silkscreen diagram on the on the backpack itself well so if I did solder them upside down that's on Adafruit okay so I have sample code running on the new node MCU and no display they're reporting to the serial monitor let's find out no it's not that's interesting although that probably because serial set up for a 9600 baud let's get set on 11 and 5200 they reset it here there we go although now you can actually see but it just says backpack test night I'm not sure if test is the regular it's the simple code from the librarian from the 7-segment library I'm just trying to see if it writes anything else to serial more than that I don't know if it does and won't know it doesn't the sample skipped right 7-segment backpack test but it should display different numbers and words it should display a counting number on your low digit display I looked at look at the product page and you did not solder yourself side down okay yeah that's good that's comforting yeah although unfortunately I'm end up getting to a point where I might need to deal with a little bit more of this off camera because I have another thing that I need to get to and that's pretty soon I see yeah we have been at it for a while yeah it's unfortunate but it's useful for us to discuss all the different troubleshooting options so I would say can't get the 7-segment sample code working then you're definitely not going to be able to get the project code working because you need to be able to talk to one display before you can charge of six that seems reasonable and um what a pity and it looked like you did everything right but it's so possible you have a cold solder joint somewhere although we've tested continuity so not likely but I guess your next step would be to desolder one of these displays so that you can test it in an isolated environment without so many solder joints in between it and the board yeah right just to double-check that it's not your soldering but it didn't look like it was but you know the proof is in the pudding if it's not working it's not working yeah like say because here's the thing when you try we're not going to deduct of reasoning here the things that are possible to go wrong are that like the most likely things are that we did some kind of wiring or soldering mistake that we can't see right now less likely are there's some kind of manufacturing problem and that you could test for that by changing the address in the test code and trying to test one of the other displays so like change the address to the so without modifying your matrix backpacks that you already change the addresses on you can change the address in in the test code 207 107 for to get your to run that test on the other individual matrix backpacks which is the way to test and make sure that your first matrix backpack isn't broken because if one of them is broken I'm not sure if it would affect the rest of them are yeah yeah this is where I just need to like pare down and make sure do you solder one and try it by itself right yeah Tyler boo-boo well if you want to cut to me you can show the working one that I have in my hands okay for some narrative closure there we go work yeah we're gonna work you know projects take more than one session sometimes to get right and when you can where can you get the different displays this is the one where there's three and one and then this is the YouTube one so you can see that if you have fewer than 10,000 subscribers you can get away with just one of the four-digit displays and then if you have more you can add on another one and have the number be continuous in front or like across the two displays yeah okay I'm confident you'll get it working Tyler without the pressure of us all watching you well so that was our attempt at building the social status tracker on make life sometimes it goes well most the time it goes well but sometimes you end up with something like this I promise I'll get this figured out and I'll post something to social about what the issue was so that you can kind of follow along I think I just need some offline time with this to you to figure it out and and troubleshoot it in the meantime I want to thank everybody who joined us watching this and all the great comments and and and questions that you asked of course

Instructables since that's where I work you can also find me on Twitter and YouTube and Instagram at brick halfway I Bek 88 WIA or just google my name at Eastern and you'll find one of the hundreds of project tutorials that I've made on the Internet over the years my dog came to visit goodbye oh hello and of course for us well we also need to thank our good friends at digiti who make this stream possible if you're once again not familiar with who they are they're an electronics distributor they sell all the components that you can put into this project as well as anything that you are working on or want to be working on they sell it they ship fast they're awesome to work with and we will be looking forward to seeing them next week in New York but in the meantime Mike we have a stream that we're doing tomorrow afternoon because we are gonna be kicking off make volumes 65 that's right that's right yeah and we're gonna be joined by if' from little bits and the rest of her team there she's

  • Just a heads up you guys realize you can now edit the live stream intro off the original files so we doesn’t have to fast fwd

  • This is the saddest thing I’ve seen in a while. Your social media presence is not you. It is nothing.
    Go outside. Do something with your family or friends in real life. Building stuff is phenomenal, but this contraption is a snapshot into exactly what is wrong with the world nowadays.
    Make, you people are awesome, but this is not a healthy building experience.

  • Thanks for joining us for the build! Here's the tutorial: (and the youtube display

  • Why not create a Cron job batch

    apt-get update && sudo apt-get upgrade

    and have done with it.
    I didn't get a notification from Becky Stern about this stream.
    What about Yellow for twitter, Red for Youtube and Blue for Facebook,
    What about building a sonic welder working at 38KHZ,
    What about a WELLER 8200D.
    Should you not strobe each digit select line at a 100KHZ so that the digits display well.
    Use a WELLER 8200D to heat up large joints when soldering large joints.
    if Your Windows Streaming box gives up then what about nuking the hard drive and installing the latest version of BeOS 5.0 Professional and UltraDV should get you back up and running as BeOS was built from the ground up not to crash for any reason and be reliable.
