Good morning everybody. Good morning, good evening, good afternoon to everybody hanging out all over the world. Yeah, we have a fun show today, lots of interesting demos and prototyping stuff. So we'll get through the housekeeping in the beginning of the show. And then we'll jump into this week's product that we're taking a look at. We have lots of LEDs, thousands of LEDs for this thing. Yours literally has a thousand, mine has like several thousand. Lots of LEDs. There's so many, they're like dust. It's just everywhere. Literally. I thought that was dust, that was cleaning up. Let's go ahead and jump into the show. Starting off with the housekeeping. Okay, here we go. If you head over to the Adafruit slash free, you can find all the different tiers this week.

Here's the team. I don't know why I clicked on that button, but it's great. We're hanging out. Sorry, I'm trying to... Okay. No, wrong one. Hello, everybody. We got some gunk droids by Yanni. Thank you, Yanni, for sharing that. All right, let's go ahead and jump into this work to this week's pretty awesome updated product. You heard the audio, right? We're good. Okay. Why is it so... Look how small it is there. It's going to drive me nuts. I'm going to just turn that off and then we won't have to look at it anymore. There we go. That's scary because now I don't know if we have any audio. I'm listening. Okay. I appreciate you listening. Can you folks hear that? We're good, right? Okay. All right. Well, this week we're taking a look at the new ESP32 V2. I almost said the wrong way, but I caught myself. There's so many different variations of it. This one is a really good one for running MicroPython. Oh, sure. My favorite thing is honestly Whippersnapper. Whippersnapper is Adafruit's easiest way to get IoT projects going. So this is the new ESP32 V2 and some of the additions is it's got the Pico Mini 2, which is this little guy has a Wi-Fi and Bluetooth connectivity. It's a small package. There's a lot of room here for the mounting hole. So I have it mounted to our little 3D-printed Lego Stemic mount. It supports Lego studs. So you can make a fun, quick project with just kind of moving these around, sticking them around. So I have a Stemic QT sensor here. This is the ATH-20 temperature humidity sensor. And what's great about it is you can just plug and play different Stemic sensors now. The version one of this ESP32 HAZA board did not have a Stemic communicator. So this time around, with the smaller package, it now has all that room for awesome things like more RAM, your Stemic QT, and even a little NeoPixel and an extra button here. This is a software button that you can play with. But yeah, you get all of the pinouts here. I'm going to take this off. Mounting holes is awesome because you didn't have them sort of on V1. You know it's V2 because it says V2 in the background. Lovely silk screen, either by Lamar and or Phil B. And yeah, it's a great little piece of kit. It's really nice feather that does Wi-Fi and Bluetooth. So we will take a look at setting it up on Whippersnapper. Whippersnapper is free. It's in beta right now, but it's definitely usable. So check it out at io.edifruit.com. Here I have our ESP32 V2 dashboard and Whippersnapper. I have set it up and in your Whippersnapper dashboard, you get a glance at all of the hardware that you have kind of played around with. And what I want to note here is that each board, you can see exactly what beta number it's on, which is super cool. You can see they're all offline because they're normally battery powered or plugged into the wall, so I don't have them online. But you can see here the 32 is online. That's awesome. And you can see it's at a date. So I'm going to go ahead and click on it and update it. So if you want to update your hardware, maybe you were playing around with Whippersnapper a few months ago. It seems like we got betas like every week maybe. So to update it, we're going to go to device settings. And here you can change the name of it. You get an idea of what it looks like. I'm just going to click update. And we're going to update it live. Hopefully it works. If not, we will report the bug. Yeah, maybe I should have tried this before. I think it's updating. I don't have a clue as to what it's doing if it's doing it or not. Anything? Maybe it's a Safari thing. That's what I was going to say. Yeah, so it is in beta. But what's cool is that right away, you can start playing around with some of the things. It's got a built-in LED. And you can add all of these components to it if you want to start playing around with different sensors and components. Right now we have a handful of StemAQT breakouts. Here you can see the AHT, a BME 280, and a couple other ones. And we also have a learn guide on adding your own. So if you want to add your own, you can follow through Brent's learn guide and create your own component if you want. I'd really like to get the battery monitor on here so that I can find out exactly what my battery level is. Because I'm always afraid that the battery's going to die. So it'd be cool to have this hooked up to the battery gauge, the battery monitor, StemAQT, and then have a sensor tied to that so you can kind of monitor the thing. I haven't walked through it, but it's definitely able to do so over here in the I2C component page. It walks you through installing or setting up your own component in Whippersnapper. There's also a dedicated Whippersnapper guide that you can follow along with if you want to see what's supported and stuff. But yeah, that's a quick look at the stuff. I have a dashboard as well that I've created. This just gives you a visual indicator of like plotting the humidity and temperature in a little pipe graph thing. Not a pipe graph, but a line graph you can see here over time. It's tracking it every minute or so, every five minutes, I think. Update if you want to pull it every 10 minutes or whatever, you can change that here a couple hours or so. Yeah, I really like the I2C temperature sensor it seems to work with just about all of the boards. So that's a quick look at the ESP32B2. If you got yourself one, definitely check out Whippersnapper. I recommend trying it out. It's really fun and easy to kind of start plotting data in like a few minutes. A quick question from Vince, asking how stable are these Wi-Fi boards over a long period of time? It's been used in the ATC Wink 1500. I would love to try something more affordable. Yeah, sure. They're pretty robust. I have here an air quality sensor that's been on for, I don't know, a couple of years now. Since we released the project. Yeah, it's outside in the front of our house and it's just been on for, I don't know how long. At least two years or more. Yeah, I need to take a look at it though, because it's just sitting out there, but I think this is the latest data. A while, depending on your Wi-Fi router and stuff, our Ryder goes down up and down, so it might be offline right now. Yeah, this is kind of a testament to like, yeah, it's pretty robust. This is actually the ESP32 V1, I believe. Let me do a quick look and learn guides and see what that was. Do you remember the name of that? Air Quality Sensor. There it is. Air Quality Sensor, 3D printed enclosure. What's the... Oh, it's the... Okay, so we used an M4 and the ESP32 Wi-Fi Co-Processor, so that's like an add-on if you want to add on. It's not the same chip, it is the ESP32, but it's not the Pico module like it is here, so I don't think this one does Bluetooth. But yeah, this is another option. If you already have a microcontroller, like the M4, the M0, this is a good way to kind of get that. Just kind of add on Wi-Fi. You can see this module's bigger here. It's the W Room 32. And speaking of the Pico module... It's running pretty good this whole time. Yeah, we have it running with the BME280 or 680 and the Air Quality Breakout, the PMSA03i. It's a nice air quality sensor. Anyway, what's up? Is that good? Yeah, we're going to take a look at the Pico module, the 3D models for it. Yeah, so as a part of the new board, we tend to make a 3D model of the PCB itself. So here it is. Here's the learn guide for the ESP32 V2 Feather, all the lovely documentation that you have grown to a custom to. Under the downloads, you can see the schematic and a screenshot of the PCB and EGLE. And really, what you can do here is find out exactly what the data sheet is for any given module. In this instance, it's the Pico Mini 02. So I was able to pull this up, and here's two different flavors of it. So I know it's this module, the ESP Pico Mini 02. So what I recommend, if you were making a 3D model for your component, for your board, definitely check out Digikey. Digikey, I searched for the ESP32 Pico Mini 02, and here it is. There is no photo for it, but there is a data sheet, it's a PDF, you can check that out. But my favorite thing about Digikey, you scroll down here, under Documents and Media, 90% of the time your components have a link to a CAD model. So here is a link to a step file, it's a 3D model format, from SNAP EDA. So here it is SNAP EDA, it's a website that creates a bunch of 3D models and footprints. So if you wanted to spin up a new board and you didn't have the footprint, and you didn't want to draw it for three hours, you can just download it from SNAP EDA. So I have an account, it's free to do so, and then they have these models here. You can kind of revolve around it just to get an idea, like yeah, that's the right package, that is definitely the right one. All the footprints are there. So I download it as a step model, and I'm going to start modeling it. You can grab the EGLE CAD file, that's linked here. So under the Downloads page, under Files, you can see here there is a PCB file on GitHub. So I will download this, open it in EGLE, and use the Fusion 360 Convert thing. It just kind of spits it out, so the 3D model, and then I can map all the components. Yeah, and I will be using the component from SNAP EDA. So let's just look at what I'm going to do today. Yeah. But the mounting holes for the feather are pretty standard, and it just worked out of the box with this one. Prior to this one, I think I had a feather RP2040 in here, and it has kind of the same mounting holes. So that's another awesome thing about feather ecosystem. If you already have a 3D printed thing, or a project that has mounting holes for the feather, your ESP32V2 will just fit. How about that? Yeah, and I can be confident to disconnect this, because it's battery-powered here. So there you go. Cool. So sign up to get notified when these are back in stock. We've had a short stock of them, but we're working on getting more. And this is kind of expressive, shout-out to expressive. They're kind of the only chip you can get right now. They're expressive in the RP2040s. It should be coming back soon, so make sure to sign up on the product page. Put the link to that. It's a PID 5400. There you go. And I think that's it for this week's cool look at new product. Yay. Hope you all like it. Pretty cool. All right, let's go ahead and jump to this week's prototyping. This week we have an update to that little connection machine we've been working on with Phil B. This is one of those iconic giant computers when they were like mainframe back in the, what, 82s when it came out? Made popular on lots of films. One of them being Jurassic Park. It's featured in the back. And here is Lamar and Phil. The animal was there too when they checked out the museum of, what is it, the MoMA? Yeah, the MoMA Museum of New York. Yeah, you can see how big it is there. Lamar for scale. And you can see that the LED matrices on the back are displaying like system load. And beyond that, Phil B is going to add some cool audio visualizers and some of the animations that we're seeing in the Jurassic Park clips. So a nice little smooth animation. Bigger one since it's so big. Since it's so big. It fits right in the palm of your hand. This is of course fully 3D printed. It's in three parts. We've got your front and your back and your bottom. It is being powered by a Raspberry Pi. A little bit overpowered, but Phil B is going to work on a, one that'll work on a microcontroller if all you're going to do is display the matrices. You can see on the inside here where the Pi is mounted and how all of the cables are all connected and running on a couple of headers down there. Nice and removable. Little back panels here with ample amount of ventilation since a lot of the, like the detail here, these cool little triangular vents were supposed to like bring in the air and then like push it out through the top. So we've got all these vents all over the place and then even on the bottom here to make sure that your Pi is nice and cool. You also have a bunch of mounting options on the inside so you can add an additional fan. And where am I? Right there. So we can add brackets to add the fan and like sort of do some circulation inside there. Of course the front here you can see how we're using the black LED acrylic to have that nice diffusion effect on the matrices. So we're using the Charlie Plex matrices or is it a loose one? They're 9x17, 16, something like that. So you have the LEDs and then the driver backpack on the back there. These connect together and just press fit onto the front there and the black LED acrylic just slides right in like that. Give you that nice little diffuse look and what else can I say about this this really nice Octoprint case is what I'm going to use this as and the microphone that Philby's going to use is just a little USB one that plugs into the back so you can do the audio visualization. Yeah. Yeah, so there's going to be a couple of different demos. Right now I think this is showing the activity of the Pi. Is that right? I think it's like fake activity but he's going to actually get some system load info in there. That's cool. All right. Yeah, so all of these are days to change together with I squared C. Yeah. So just zero clock and zero data, two data lines, voltage and ground. They plug into what? Just the headers on the Pi? Yeah. Just plug into the headers and then you're doing some addressing for each matrices on the back here. We'll show it in more detail next or actually yeah, next week. The way that they're soldered to show which address each of the matrices. Yeah, that's what's great about I squared C. You can assign different address buses and then have just eight of them all and then you have the octo over here. So you have eight of these matrices all going together. That's over a thousand RGB or just regular LEDs. These are just regular LEDs. You can choose the colors and whatnot. You can't change the colors because the LED is the color. They are not NeoPixel. Yeah, not NeoPixel. I will pull up the product page for the Charlie Plexus. I think we do have a couple of those in stock if you want to start building this guy. Yeah, you can see the red ones are in stock. You do need the thing in the backpack to drive it because it's just a board for just having the LEDs. There's no actual circuitry on it other than the traces for the LEDs. But you need to power this. You need to drive this with something and the driver is over here, this guy. 16 by 9, yeah, PWM. The other D-matrix driver using the ISFL. IS31, FL3731. Love that one. But yeah, you can do all sorts of fun things. And we have used this backpack before. If you remember a couple of years ago, we came up with this... Oh, a incredibly cute little pet. Yeah, so making many retro computers is a thing. We love doing it. This is our first one, I don't know, five years ago. Let's say a little 3D printed thing, just one of these backpacks. I think it's a feather and fake keys. A 2D printed thing that's already, like the sticker's already peeling. It's a great little project. Awesome Arduino code from Phil B. Oh, look how you put on there. It's running the Feather M0. Right, so it's actually running an older, yeah, the Melsan D50. Little guys. I can't focus. But anyway, it's using very similar, instead of red, it's green. It can do game of life and some text and other things. We've got a nice Adafruit GFX library runs with it for Arduino. And we also have a Cirque Python driver as well. But this is all done in Arduino, because we didn't really have Cirque Python back in the day. Mouthing about the exact same thing with the little numbers. Oh, really? With the standoffs on the back there, because you can't really get the screws in there once you attach the backpacks. So everything is fully removable, completely modular. So if you wanted to swap these out for different matrix C color, you could do that. Or if you just want to do away with it, have the case be something completely else. Yeah, plenty of room for a ton. My favorite Pi case so far. It's such a cool Pi case. Definitely going to keep this around. If not a Noctoprint case, at least with the... When he moves this over to Cirque Python on one of the feathers, or a Pico. Definitely have this as a nice little display, like our cool little LED matrices in the background there. Yeah, so this is the website from MoMA.org. This installation is called Thinking Machines. This is the CM2, right? This is the model. They had a CM1, 2, 3, and I think all the way up to 5. Yeah, the 1 and 2 were similar. I think it's just like specifications and process or something. I thought this was actually a real thing. This is actually a replica I did not know. Where does it say that? Oh. Where does it say replica? There's a link in Slack. Did you see that in random? No. I can pull it out real quick. Just bear with me, folks, please. Is that being shown? Yeah, here it is. Blinken Labs is the company that worked on making it, making the replication. Replicolites for the CM2. And they have a picture here of an Arduino. These look like bear LEDs. And they maybe wrote some software to do that. I don't know heat stuff. Is that a teensy? I don't know. I thought that was a real thing. I did, too. So check out this video as well. Maybe I'll put a link to it. Yeah, let me just link to this whole page and folks can get an insight. Next time in New York, I definitely want to see this if it's still around. That'd be great. But this is a great interview with one of the consultants, Gordon Bruce, who worked on the project. Yeah, and they have some fun interviews. Nice little discussion on the design process that I have. What was it? The belt? The waist belt or something? I don't remember. But I added all that detail in there since Philby did have that in the base camp. All the detail that needed to be in there. So that was a nice little challenge. I figured out how to get everything to go. Used some support materials, but it turned out phenomenal. Really happy with the quality of the printing out on this. It's going to open base camp and start poking around it. We could do that next week. Just in case that next week we don't do the show or something. Let's see. Alman Chattery on Facebook is asking which this are we talking about? You can get all the parts. This is a sneak peek of the audio visualizer code that Philby is working on here. And he posted a really cool demo on Twitter as well. So here in Jurassic Park the first one, you can see where it was it's basically in every kind of hacker scene. Honestly, I don't remember. As a kid watching this, I don't remember seeing those in the background because I don't remember them being next to the screens. It was always in the background. I like the way that every other two rows are moving in opposite directions. Did you film this with your phone? If you're watching on your laptop on HBO Max it was great re-watching it too. And knowing what to look for it's in that scene. It's such a visual thing getting all this nice bokeh in the background of the shot. It's really cool. That'll be next week's super cool little pie case. Super cool little pie case the little connection machine CM, connection machine. CM1 slash CO2. That's what we're preparing. I think you have something too? Yeah, I do have something too. Cool. So we have cubes this time around. Lots of cubes. I've been working on a a 3D RGB matrix cube. This is it. We're going to have two versions of it. There's a bigger pitch for these 64x64 RGB matrices inside here. It's kind of hard to show everything right now. Raspberry Pi is in there and a matrix is in there. These are six RGB matrices panels. What we came up with is a system of lining up all of these frames so all of these frames will be attached to each of the RGB matrices. They get mounted with these corner mounting holes and each side has these letter tabs and the idea is that you link up, you just match up the letters and with these magnets and alternating tabs they just kind of snap into each other. So it took us a minute to figure this out because we only want this cube to be assembled one way because in the code mapping all the orientations is quite difficult. So this is one version of it. The second version is the RGB matrix that's just bigger. It's a 2.5mm pitch. This one is the 2mm pitch. So what I'm going to do now is plug it in. The way we have everything powered is through a 5V 3A 10,000 mA LiPo battery. It's huge. It does 3 amps. The Pi 4 needs 3 amps so if you're going to try this in the other battery make sure it can do 3 amps. So the RGB matrix bonnet has to be powered separately but this battery is beef enough to power as you can see I have two USB ports one for the Pi. It's going into the USB C port and this USB port here is going into the 2.1mm barrel jack on the bonnet. We have kind of shortened out these power cables and are using these screw block terminals to share all the power and bus but this all needs to be daisy changed correctly. I went ahead and snapped it down. I'm going to run the globe demo so I'm going to SSH into the Pi and launch the demo in just a moment here let me do that again ok so I'm going to CD into the thing and then run it and here we are. So this is a great demo from Phil B Phil B is doing all the code and he needed to come up with a way to test the orientation of all the panels and make sure that everything is mapped properly so this is an animated globe it's spanning across 6 of these different panels I think we need to go to the yeah sure there you go so there it is it's about 133mm big and it's kind of heavy it's very heavy it's drawing a lot of power and a lot of current that's why we needed a beefy battery that can do 3 amps because the Pi 4 is power hungry it gets hot as well it's getting warm so we might put a heat sink in there I've only run it for about 30 minutes so we'll see what's the total time but it's cool that when you want to take it apart you can just take off this bit here and shut it down but yeah it's cool to see the map kind of animate across 3 of these panels so imagine if we had a texture map of a human head it'd be really creepy so yeah let me run another demo just because it can with a life demo yeah so this is the Conway's Game of Life it's got a couple of different colors and the real impressive thing is that the cells are spanning across well sometimes it's hard to I don't know why they all kind of disappeared and like stopped working demos yeah I think I killed it let me run it again that's one way to look at it but you can see how the cells are going across the panels there and really the last demo is to show sand the sand demo, pixel dust showing there's an accelerometer in there as well I forgot to mention but that's really just for the sand demo we've done sand demos before with the RGD Matrix season and the Mar has always wanted a cube boys, a cube difficult mainly on the assembly front I'm going to stick with the globe, it's just the best demo for it and Artica, where is he? Artica let's spin around question from Mr. Cernan Bruce is asking did you look at the snap action 5 wire block connectors on the shop PID 874 so I need more than I need more than what is that 5 that only gives me 4 we needed the power the rail we have is in the shop, do you want to pull it up? I think just call it power rail this one was recommended by Phil B it's a nice chunky one power bus yeah these guys these are great, they're super chunky they hold a lot of current and they have just the right amount of pins, 7 of them for me to do it so that's how I'm doing it it comes with screws and all that it has mounting tabs but as you saw inside the cube there really isn't a spot to mount it so it's kind of reloading in there but this is the power bus I use this is real cheap, it's like $2 oh wow they're great for these thick wires each panel comes with a power cable and an IDE data cable the power cables are kind of chunky, right? they're literally like this thick hey look there's a cube from a few decades ago that's a great one too yeah so any other questions? the chunk is important yeah and it looks beautiful yeah the bigger one is you want to hold this up while I hold this one up? the difference is I haven't held that one, how much heavier is that? well there's nothing in it yet, it's already heavier but yeah this is the 2.5mm pitch so you can see it's not that much bigger but yeah it has the same kind of principle but it's a little bit different these have curb cut frames they're at a 45 degree angle which allows the assembly to be much easier much easier you can see inside there we have a 3 printed bracket for our Raspberry Pi same thing with magnets the accelerometer goes in the middle here so you can see these 4 standoffs and there's just magnets there there you go and then these corner brackets here are all secured with screws because you have these really nice heat inserts embedded inside the frame the curb cut frame for the smaller like I said we had to recreate the frame so that was vastly more difficult than this version I think though the smaller the panel the more expensive it is so it's one of these very costly fills that kind of just shows that you can do it but that's I think 2 weeks out, 3 weeks out nice little flex video very cool yeah so that's what we're projecting it's nice and warm now get the whole world in your hands I'll be gentle a little bit Yanni says it looks like Lego and to Wester so the world or so the earth is flat flat but in 3 dimensions Cuboid hey that's a cool demo that Yanni posted the sweet wow check out discord at discord.gg slash Adafruit to check out all these sweet memes I had this as a Minecraft block which looks really cool I also played around with the portal cube 3D Tetris yes but remember the accelerometer so it would be cool to do some sort of accelerometer funness and then there's this funny guy saying that yeah it's great for the manufacturers to realize these are likely to be used by people wanting to make cubes and angle the frames and make it easier yeah it's a little bit tricky to get these overseas with everything going on but yeah Lamar managed to snag a couple yeah they were like on the boat stuck on the boat ah Andy Callaway coming in with the important questions where's the 3D party parrot yes that's that's a great idea alright so that's what's being prototyped yeah it's a big prototype segment this time around sweet alright we're ready to jump into let's go ahead and check out this week's community makes this week is an awesome I like the design of this sweet little wearable it is a dragon hairpin it's so cool this was supposed to be released during Halloween but not enough there were too many Halloween projects so got pushed back so as we're seeing here I did have to do some chopping up of the model mostly just slicing it in half so it doesn't fall over and getting all those nice little details in the horn same thing with the sword just chopped it in half so I wouldn't have to print it straight up could do a little work with like welding and then like sanding it all down if you want to get rid of that very visible jointing line there but for the most part it looks really good it looks like how smooth it is and yeah it's a really cool dragon hairpin to go along with your cosplay so it's be like a skull for the dragon and again I did chop it up right here just so it would print vertically and have some nice smooth details here on the horns and here's the sword goes right into the eye here to hold up your hair and this is just chopped right in the middle down the center here so it just prints flat so I don't have to print this one vertically because of the T right here although I guess I could have chopped off the handle and printed it upwards to get that nice detail with a little crystal pommel but for the most part oh yeah prints super well really happy with the way the quality of this came out always an excellent technique to take a model split it somewhere where it makes sense and avoid some support material gives you a flat surface to do to the bed as you can see in the time lapse it did fail and I did try printing it upwards like cutting off a little beak here I'm bringing it up but even with the z-hop it kept hitting when it gets down to the top I mean this is a pretty complex complex up here as you start getting up to the horn so a nice little way to have a larger surface area on the bed with this instead of having this little tiny area down here this is by Angry Ant Eater on Thingiverse so Angry Ant Eater thingiverse closer to that up so if you want to mix from a skull hairpin yeah I think we've posted this one before on the blog or did a video of it but I think that is Angry I thought it was Antler Ant Eater bubble very cool and the original model is like this you can see split that in the middle what you use to split it Prusa, Slicer and do that in Curie huh not the way this slices it almost looks like a good cut there very cool alright well shout out to Angry Antler Angry Ant Eater for posting this up as a free download yes I do not believe this is TSA approved even with this soft I think you might be able to cut with the edges here oh you brought that too you might have to leave behind the sword and then Rawls is asking the amps that the cube is using I think you said 3 yeah the battery is a 5 volt 3 amps it's a nice battery you can get it on Amazon just search for 5 volt 3 amps 10,000 milliamp there's only one that I found there's probably more but yeah all of the batteries in the shop will not work because they do not go up to 3 amps they only stop at 2 amps yep we tested I did not work I risked burning out my pie which is a very bad thing to do right now so hang on to those pies or have a backup SD card ready to go when your pie is short when you've shorted the power thankfully I didn't short the power alright I think that's it for this week's community mix no mix this week yeah we don't have any mix this week so that's great chance for everybody who's doing it up probably still on the beds as we speak getting printed out yeah so thank you so much for hanging out with us but don't go anywhere the rest of the day later on tonight
