 Welcome back to another 3D Hangouts. My name is Noe Revez. I'm a designer here at Adafruit. Joining me every week is my brother Pedro. Good morning everybody. I'm Pedro. It's creative tech here at Adafruit. And every week we're here to share 3D printed projects featuring electronics from Adafruit. That's right. This is where we combine 3D printing and dual electronics. Bring them together to make inspirational projects for you. Hello everybody. We are hanging out in the Discord chat room. If anyone would like to join us live during the show, you can send us comments, questions. You can do so by hitting up the Discord chat room. We're hanging out in the live broadcast chat room. That's over here in the sidebar. And you can get an invite link to that by heading over to discord.gg. I'll show you the fruit. Hello everybody in the chat room. Pedro is going to say hello to you. Good morning everybody. We are hanging out in the Discord on the YouTube, on Facebook, Twitch, Periscope, LinkedIn. Good morning everybody hanging out. Joining us every week. Let's go ahead and jump straight into the show. Okay, cool. We'll give you shout outs after the housekeeping. So let's keep this house. Hundred days of masking is still going on. I don't know how many days are left, probably a few. But if you pick up anything in the Adafruit shop right now, you'll get yourself a black surgical mask. If you go to Adafruit.com slash free, you can see all the different freebies that are going on. Wow. For orders that are a dollar or more, you get the mask. For orders that are $99 or more, you get the mask plus the perma proto half-slide breadboard. For orders that are $149 or more, you get the perma proto, the black mask, and a free stemma QT board. We are talking about stemma QT later in the show. But if you want to get a free one, make sure you spend more money with us. For orders that are $200 or more, you get the free stemma of QT board, the free perma proto half-slide breadboard, and the black surgical mask, but we're not done because for orders that are $200 or more, you get free UPS ground shipping. The stemma QT breakout, the perma proto half-slide breadboard, the black surgical mask, it's still not done. For orders that are $299, you get the free shipping, the stemma QT breakout, the perma proto half-slide breadboard, and a free black surgical mask. So please do yourself a favor and spend more money with Adafruit because we need your orders. I was going to say, but there's more. Is there more? I forgot to do the Billy Mays. But there's more. There's also help wanted. If you want to help and get paid for it, check out the new jobs that are added to the jobs board. You can head over to jobs.adafruit.com. You can see all the ones here in the blue are great. So check them out. I like Mike and Spires. Check them out. They're looking for a maker space manager in the New York, New York area. So if you are in the New York, New York area, check it out. That is so cool. And there's other things like executive director for open source initiative. Nice. That's super cool. It's free to make a profile, whether you're a company or a maker. Hey, and that one's remote. The open source director. Yeah, all of them should be. But that's me. Okay. What's next? We had a circuit. Python meetings happen on Monday at 2 p.m. These happen in the Discord server. So if you'd like to join in on those meetings, you can do so. We like to hear from the community as well as the core devs, what they're working on, and then concrete stats to keep them grounded. I'd like to say Blinka is a cake and it tastes good too. All right. Hating on over to the newsletters. AdafruitDaily.com is where you can subscribe to all of the newsletters. My favorite one is Python on hardware. You should check that one out. 3D printing is good too, but Python on hardware is what I really like. So check that one out. And all the other ones that are there too. You need to subscribe to them because we don't automatically do that because we're Adafruit and we don't spam. If you go to adafruit.com slash newsletter, you'll notice that it's different from the daily newsletter. This is a weekly product-focused newsletter. Everything that gets added to the Adafruit shop biweekly gets added in this newsletter. So if you want to check that out, adafruit.com slash newsletter. That's all of it, man. I ran through that. Pretty good. All right. What's up, everybody in the chat room? We having fun? Good morning, John Hendrickson. Of course, good morning, Bruce. And in the YouTube chat, it's just us right now because it's early. Good morning to Leon Diaz and we're on the Facebook and on the Twitch. I missed Leon. Sorry. There you are. Good morning, everybody. All right, let's go ahead and jump on to this pretty cool project for the Feather RP. 1440. This is the first time we've ever had a, let me refresh, this is great. So we did a demo, oh no, it's gone now. Sometimes it happens. There it is, the Feather RP 2040 is in stock. It's like the cheapest Feather and it has the most features from any Feather, I think. So check it out. Here we have a little demo that we put together for the Feather. So this is running, this has a new RP2040 chip from Raspberry Pi. It's running CircuitPython. This is a little demo code. This is a sensor. It's the DME680 sensor. And my camera won't focus. This is live streams. I'm going to click all the buttons. All right, how's that? Is that better? Sweet. All right, so we've got the Feather right here. It's running CircuitPython. You plug this in through USB-C. It shows up like a USB drive. Whoa, there's all the code and the library files. That's the beauty of CircuitPython. This has a 8 megabyte flash. Originally it was going to be 4, but that didn't work out. So we threw in the 8 one. So you get way more double the storage. So you can have fonts, images, bitmaps, and maybe the whole library bundle in that giant 8 megabyte flash. You'll get it before the mart changes it back to 4. This is my favorite OLED display right now. It's 1.5 inches. That is a lot of millimeters. And then over here is the BME680 sensor that has four different things. It has pressure, humidity, temperature, and gas. I know so because it says so right there in the label. And then I put these icons together. Shout out to LadyAda and Liz Clark who helped me put this code together because I don't write code. But CircuitPython, you totally can. You can write code and not be a programmer. That's what's beauty of CircuitPython. This is a Lego plate. It's official Lego. It's got the Lego thing on it. And I put together one of these brackets here that are 3D printed. All of these are 3D printed and they're already available. And we'll take a look at the Learn Guide and where you can grab these if you want to use a Lego base plate to put together your projects. Very cool way to do so. And this is 8 Bot. This is also a project. Oh no, I did not link him. That's fine. And then this is a little 3D printed Razor Pie. Kudos to Sudo Warme who gave this to me. Excellent. That's the demo. Feathers and stocks. You can grab that. We have a maximum limit 10 per customer. But hey, never there. It's like 12 bucks. It's the cheapest feather we have because that RP2040 chip is good. Yeah, what else can I say? All right, so yeah, the grayscale OLED 1.5 inch display is awesome. This has two Stemma ports on it. So you can daisy chain more Stemma connectors and Stemma breakouts as you saw in the demo. I have it hooked up into the feather. No soldering here, no headers. You just plug in these cables. And then on the other side here, you can plug in a thing. And then because the Mars is making just about all the Stemma breakouts have two Stemas in and out, you can daisy chain more and have a longer thing if you needed to. So that's freaking cool. So this display, one of my favorite now, we used it in the MIDI Pico project from last week or maybe two weeks ago. And it's my favorite display right now. It's 128 by 128. That's the pixels. It works over I2C, but also Spy. It's got breakout pins on the top there if you want to share any of those. You can still solder into the breakout. And the mounting holes are in a great spot for mounting it, panel mounting it, or 3D printing, a thing for it. Very cool. I also have a 3D model of the thing. So you can check that out if you want to design an embedded case for it. Here it is running with a QD Pi, which is the smallest circuit Python board you can get. That's really cool. Dude, the feather's cheaper than the display. That's crazy. And then for the Stem-A breakout sensor, this is the BME 680. It's out of stock right now. But you can sign up to get notified when they are back in stock. It has the four things, the pressure, humidity, temperature, and gas, which is pretty crazy. And it just works really well with circuit Python. It's got a really good driver. It's super easy to spit out some values. It is available on Digi-Key, so you can buy it through Digi-Key if you'd like. We do have some products that can be purchased through Digi-Key, our favorite reseller partner, one of our favorite reseller partners, as I'll say. Yeah, what else do we have here? I think the Learn Guide for the feather. Yeah, Learn Guide. Yeah, if you'd like to get these STLs for the LEGO stuff, we have a Learn Guide called Stem-A LEGO Baseplates. And that's where I shoved them all. There's a, oh boy, our Learn Guide just took us out of here. Let me try to work through this. So you can download the STLs or get the Fusion file if you want to modify them, like the original file. You can download a step file if you want to use a different CAD package. And they're all labeled here. But yeah, the addition ones that we did for this particular project this week was the 1.5 OLED, which is right here, and the little battery, which is the 400-milliamp battery that's ideal for feathers. This one here, it's a 400-milliamp battery. This just slides in and out of the little retainer there. And then on the bottom here, we have these little pegs that fit into the thing. They easily come apart because it's designed to kind of do so. So you want to be careful not to apply pressure to the battery. That's why I don't have it super tight. It's just a little kind of fitting. It's kind of a loose fitting, rather. There you go. Cool. They're available on Thingiverse as well. Let me pull up the Thingiverse page if I have it. Maybe I don't. I did, but I don't now, so it's fine. I think this link will take you to, well, maybe not. I'm in edit mode. This link will take you to the Thingiverse page. And I will switch to that right now. Here it is. It's on Thingiverse. We'll add it to other sites, but for now it's on Thingiverse. This is a page that the page will put together, a couple. I don't know. That says on there. Oh, September 15th. Yeah, a little bit ago, when the cutie pie came out, we figured, hey, let's do all the Stemma stuff in LEGO format, and we continue to do so now. We'll add, of course, more parts as we get things. But there's a whole bunch of them, so that's great. The LEGO bits. They are printed in two pieces and then glued together. That way, you can print it without any supports. You just glue the pieces together there. I'm trying to take off the spinning. There we go. So that's why I had to pick the black one, huh? That's hard to see. But there it has built-in standoffs for these style of things. Mountain holes. Yeah, the bottom here is just kind of glued together. You can't quite see the seam there, but it's there. And the camera never focuses, even though it's set to autofocus. It never does. Yeah, so very, very simple. Just kind of, well, I would recommend plugging it into the base plate first and then snapping it on top of the PCB. Like so, like that. This is really good on the refresh rate. Wow, like on the webcam. You barely see the flicker. There's no flicker in real life. It's just normally over the camera, you get this nasty flicker. That's so far so good, yeah? Yeah. I've got some questions about using displays. And people are linking to the massive amount of displays they can use with a Raspberry Pi there. With a Pi? OK. My favorite display right now. Very good. And it's grayscale. So you can get different tones of gray, which is cool. Coming through, posting all the links. So yeah, the Feather RP2040. We'll have more projects with it as we make new projects. I think just using this going forward is really great. Yeah. The one thing that gets me is, of course, the price, the USB-C, the extra reset button that's already attached to there. You don't have to add an extra one. And I think I already saw the recharging of the battery and then the size of the flash. Yeah, the Feather was announced. The Feather, it says Pico 2040 in it. That was like the code name. This is a 3D model that I put together when it was first announced, which was probably near the end of January. So I do have a 3D model for it right now. I want to revisit it because it's not green. And we have some beautiful silkscreen artwork from the dragon himself, Phil Berges. So I do want to update this model. But hey, look, it's got the USB-C type connector. And it's got the JSTSH4, better known as the Stem IQT port. And it has all the things that you know about. Maybe you don't know. What have they sought, 23s, SOT, whatever, whatever. Those are the package footprints for the little components. So yeah, good stuff. Hugo's asking about these. Was this the same display it was used on, the MIDI fighter? Absolutely. Yes, it was the exact same display that we used in the MIDI fighter, which is great. I'm posting up the links. If you want to grab the 3D model of the Feather RP2040 for your CAD projects, perfect for laying out all of the mounting holes or checking all of the clearances for making a case. Absolutely. And the K-Port too, the bezel around the display is always like, what's the actual viewing area, like the pixel area? So I always try to do that with my models. And you can see here it's got a nice little happy face. It may or may not be a BMO face. But hey, we have a 3D model of this as well. And you can grab that through the Learn Guide. As a part of all new products, get a fancy Learn Guide. Give you pinouts and some sample code. But yeah, works with Circuit Python and Arduino. And then I think you already talked about the little mounting base I'm using. This is a little plate. Last week, we had this on a piece of acrylic. I just increased that bit bigger. It just fits like that on the desk. Works really well. Yeah. I like this Lego plate. This is a good one. What is this, like 12 by 8 or something? I don't even remember what it came in. Yeah, it came with something, but these are great. And a lot of good comments on the feather. People are saying, don't forget, it's got the LiPo management built right in. It sure does. So if I were to plug this in through USB, which I, do I have a camera? Pedro, do you have a cable and USB-C cable? Where is the USB-C cable? Nope, that's late. We don't have a single USB-C cable in this room? It's probably in the other room because we're doing photos. You want to grab it? Let's see. Yeah. So the idea is to plug in USB-C into here and then like disconnect the battery or have the battery plugged in, disconnect the battery, and then it'll switch to USB-C. So let's give that a shot. So plug that in. Go ahead, plug that into your computer. You only have one port, right? Two, two ports. Excellent. Cool, so now it's recharging the battery. You get a little charging indicator. And let's turn off the focus so you get the, so now that I can just disconnect the battery. I can see, oh, you have to use pliers. Do you? There we go. So that's awesome. Now it's just, it's still running. The code didn't restart or anything, so that's good. And then if you plug in the battery, you can disconnect. Is that right? Yeah, you can disconnect here. And then there it is. It's switched over. Super cool demo. And then Hugo is saying that happy face is when everybody looks at the realizes how easy it was to project together with the Kinect Stem IQT and Circuit Python. You know, it's really awesome. Like, if we do have another OLED, we can switch out this OLED. And in the code, all we have to do is change like a couple lines that says what the driver is for the display and all the underlining code, displaying labels, icons would all work. We're just crazy. That is, that is the power of Circuit Python is like all the underlining code will work across whatever driver because we try to make all the drivers work what they do with display IO. So that's like the power of display IO. It's like, it doesn't care what driver you have or what display you have. Just sees it all the same. It's pretty cool. Maybe we'll do that for a demo. Some point in the future, we'll be like, hot swap the display and show like, we'll just have two different code pies. We'll just rename the name. So we don't have to edit the code. We just change the file name and quickly see how it works across displays. Cool. Yeah. Cause this original demo code isn't for this display. It was for one of the smaller OLEDs in a different driver. Yeah. So that's really cool. All right. Posted up all of the CAD and the learning guides. If you guys want to check any of those out and check out the sample codes for that. Yeah. As well as the fritzing too, if you want to make some circuit diagrams. Can you grab the other feather that's in the, the same room that you grabbed the cable from? Cause I do have another feather and I have some kind of fun demo code on it. I really want to show the demo code. This is a good way to show values from a sensor, but what if you just want to have a regular display? So here's what I'll do. I'll plug this in here. I'll unplug this here. Take that out. Swap out this feather. So this is the feather with the temperature stuff. What's on this feather? I wonder. I wonder, I wonder. But if there's nothing on it. Yeah. There's nothing on it. Ha ha ha. My demo failed. What's your computer say? Anything? It's not mounting. Well, yeah. Well, there was something on there. Yeah. There's supposed to be a bitmap of a little face. It didn't quite work though. You said it? No, because then I'll have to install the thing again. Yeah. Do you have cura open or something? Sometimes, yeah, your cura is messing with it. Tip, don't have cura open. Yeah, because it takes over the, the compor. And it sometimes it could kill your, all right. Well, that's a tip. Do not use cura while you're doing CircuitPython device. It just wipes your drive sometimes because it gives it N commands, Pedro. I should have told you. I'm sorry, it's my fault. So there's the demo. You don't have a thing, do you? Go to circuitpython.org and download the UF2. We'll do it live here. So if you go to circuitpython.org, we'll do a quick installation of it. So here I am, circuitpython.org. You can search or browse if you'd like. I'm gonna browse or go to downloads. And then in the search box, I'll just type in RP. And there it is, feather RP2040. The latest version of circuitpython is beta4 right now, 6.2 beta4. So I can grab that. That just came out a couple of days ago. So you can download that to get this guy in the bootloader. I hope it runs on the MacBook M1. I think it does. But what you need to do is, so this is plugged into Pader's computer, the M1 MacBook. I'm gonna hold down the boot select button, hold it down. While holding it down, I'm gonna plug this in, keep it held down until it shows up on Pader's computer and then let go because it shows up as RP2040. Pader's now gonna drag and drop the RP2040 UF2 file onto the USB drive. The USB drive is shown up as RP, RPi RP2. And then that's gonna automatically flash the firmware and I already have the code and the libraries on the spy flash. So even though I just reflashed the UF2, I think it broke it though. It's not quite loading. Can you, it's already been injected? Oh, it has. All right, well, can you disconnect and plug it in again? I think maybe my files got wiped. Can you look at the drive and see what the code file and libraries look like? Come on. I'm gonna have to blame your MacBook. I don't know what else to blame. It won't even show up now, wonderful. All right, well, maybe don't use the MacBook M1. I know it works, but not, I don't know. Maybe the battery did something to it. Let me try it again. There you go, sorry about that. Because it's loading the REPL, you can load the serial terminal right onto it. It's gonna keep doing that because Pigeon's like loading the file and opening it up and stuff, but that's the bitmap I wanted to show. This is a full color bitmap, but because it's using an OLED, it'll just display what it can. So there's a little bit of gray there. What a cute little face. Thank you for working. That was, imagine if this didn't work. It kinda didn't, right? I'm trying to plug that in. All right, so there you go. We installed Circuit Python on a MacBook M1. It works. Yay, and now my, there it is. Oh, I got some tips saying that you can actually disable the USB plug-in in Cura if you're not printing it directly from it. Oh gosh, that is a good tip. We didn't do that like right now. I don't know, where is that? It's just an extension in the marketplace? Yeah, I think I broke it again, sorry folks, with the M1 and stuff. And then, you can also use the reset button to get into the bootloader mode with the feather. Yeah, that's true. I think with most feathers, you can do that. Yes, yes, yes. All right, cool. So that was the point, was to kinda hotswap the feather and show different code running on it and using the same display. So yeah, yay. Even when it fails, it ends up working eventually. Eventually, yes. Let's back in and see if this can work. Yay, excellent. All right, cool, we did it. All right, so yeah, circuit python works really good. I was gonna say like, mostly works, no, it does work. And then there is, if you guys wanna go into the Discord, over at discord.gg slash Adafruit. Yeah? Can't pronounce this name. J-F, foreseen is linking to a GitHub issue that describes the REPL and the clue board. Oh, nice, from Brian Sedatius. Goody-goody. Yeah, it's funny seeing, sometimes I will see Cura's M-commands displaying on it. Maybe that's cool. Maybe that's something you wanna do. Like seeing the M-commands displaying on here is kinda neat. Maybe we can make a little, I don't know, sniffer or something. They do have accessibility options on like the, they're printers, right? You plug in a USB, H-A-D device. You can play Pong on your holding makers. Sweet, well that is the project. I hope folks check out the LEGO stuff. Here's the link to it. And also the Learn Guide has links to the thing. And pick up a feather if you haven't yet. They're still in stock. Go ahead and pick up 10. What? Yeah, pick up 10 if you would. That'd be great. All right, cool. Let's go ahead and jump into this week's, what are you prototyping? I think it's what this user on the YouTube channel is asking about, what is that display in the background? What is that display? Remember the giant sign we had here? I shrunk it down and I put it in there and I added more pixels. That's what I did. You wanna talk about that? Yeah. So that is a project I'm prototyping. I'll start off with the thing. So I got myself a 16 by 16 pixel matrix from Amazon for $20. So this is a flexible, I haven't even opened it yet, but they're NeoPixels, W, whatever, whatever. And there's 256 of these pixels. So my thing was like, okay, they're $20. How good are they really? So I bought two of them from Amazon and I wanted to see if they work with Adafruit hardware. So it totally does. It's the exact same pitch and the exact same pins and labels that we kind of know already. And I started up these three pin JST connectors to it. I have a prop maker feather wing and a feather NRF 52840. I could totally put one of these but I didn't wanna solder any headers. So we can plug this in and get our pixels running. So here I have USB, micro, cable, micro-B. So this is a 3D printed frame with some black LED acrylic. And the pixel frame is something I showed last week where I was prototyping the pitch and the pixel spacing for it. This is running Circuit Python, the LED animation library, lets you create these really awesome animations and create grids so you can animate with an arrangement of pixels to make a pixel grid like this one is here. This one does the alternating zigzag pattern. So that's just set up in there. And yeah, the 3D printed frame works really well here. So this is the rainbow sparkle effect that's a part of the LED library. This is fade, which is pretty simple. And there's some really cool ones here coming up. 160 centimeters is like the size of this. So it'll fit on a kind of your standard bed of a 3D printer, a little bit, kind of mid range build size. This is the comet animation working with the new pixel grid helper, which allows you to do cool stuff. And this is the new kind of, is it the comet? No, it's the chase animation. So that makes a really fun animation there. And then back to the wipe. So yeah, so this is super easy to take it apart. This is the frame fit. This is the black LED acrylic that we stock. We love this stuff so much. One side is matte and the other side is glossy. So you wanna put the matte side facing down and this just press fits in there. The way I was able to cut this was I printed a PDF template and then put it over my big sheet of acrylic and then I just scored it and cut it down. I just sanded the edges so that it has a nice fitting to it. The next piece of it is this grid, which takes 10 hours to print, but there it is. This is fitted inside of another kind of insert and that insert is where the screws are for attaching the doubler feather wing. So there's nothing really holding the new pixel display to the grid. The only thing that's kind of special about the grid is it has these reliefs, these little cutouts for the capacitors that are strung across the arrangement of the pixels. And this is it, it's flexible but you're not supposed to really flex it a lot because it could crack the solder. So from a assembly standpoint, it's super easy to put together. Just line up those kind of reliefs with the things there and then this has a really nice flush fitting to it. It has a little bit of wiggle room I guess, but that's not a problem. And then this fits in like that. Maybe put that down first and then this. So that all press fits and has a nice flush fitting to it. So it's a little loose but it's got real tight fitting into the frame itself. And then the last thing to do is to fit the grid into the cover. No screws for these pieces. The only screws you need are these four for the standoffs, M25 standoffs. And there you go, that's the whole assembly. Super simple. I really like the idea of building your own grid, soldering your own pixels and all that. This, because it's $20 like I just had to, man. $20, 256 pixels. That's crazy. And what's funny is it came as a two pack. Yeah, I bought it as a two pack. It was only $38 for the two pack. So you save like what, two bucks? So this is amazing. I really want to do a learn guide and a project for it, a video project for it. Yeah, I love it in the background there and having two of them or have this be something else and like some sort of midi instrument would be really cool to have as well. But yeah, I hope to do this one soon. I got to let Lamar know about it and really told her about it, just built it on my own. And some nice purple glitter filament here. I don't see. Yeah, man, this thing's so fun. I love pixels and that effect is so great. You might remember the smaller version I did, the eight by eight. I don't know where it is. Wonderful. It's somewhere. Wonderful. Fantastic. Kirk on YouTube is saying that those are cool ones. To make a cube with six of these. Ah, that is something that we might even undo. The black lady acrylic is something we love so much that we started stocking 12 by 12 inch sheet. So you can pick that up for 10 bucks for made of it. You can also get it from TAP Plastics. That's another good place to get it from. That's where we originally got it from. But we get it straight from, I think, one of the manufacturers so. So yeah, it's a 10 by 10, 12 by 12 inch sheet which is good enough, big enough rather for this project. Yeah, yeah. Grabbing all the links. And people like it. It's saying many potential uses, clocks, eye candy, whatever the prices are. Yeah, I'd love to do a sand demo where it's a prop maker. It has a built-in accelerometer so we can do a sand demo that'd be so cool. That's actually one of the other questions. The entire display to be empowered by just that board? Yeah, so when it comes to power, it's like, well, how are you powering this thing? That's the power of the prop maker feathering. You see those honking resistors there? That's what's allowing it to do it. That's what I think. But yeah, this plugs in there. That's literally, it's running off my computer. I already have like a dozen things on my computer. But the prop maker feathering has all the special circuitry to power these pixels properly with five volts even though it's, you know, a three volt logic board. Isn't that amazing? Like, that's crazy for me. The prop maker feathering is something you can pick up. It is like one of the best feather wings, in my opinion because it gives you the accelerometer. It gives you a speaker. It gives you high power LED stuff. So you can power those one watt RGB LEDs and just search for prop. And here it is. You can get it with or without headers. Here's the assembled version for 10 bucks. The NeoPixel port on the back there is really nice to have on board. So you don't have to solder really to the board itself. You can just plug and play. Yeah, it has a built-in amplifier for sound effects, built-in accelerometer. It's basically like you want to make a prop that's this is it right here. And then combined with the prop maker or rather the doubler allows you to spread your wings. You can have one feather there and then your feather wing there. So that's kind of what I have set up here. Yeah. And I just took the link to the two-pack of the Matrix. It's a really simple design. So if anyone has like some cool ideas like maybe some handles on the side or something else that I can attach to it. What if it had like an AMG thermal camera on top and then like you can see a thermal view of something that'd be kind of neat. A clock would be great. An IoT game of sorts. So you can play maybe Pong over the internet somehow. Maybe it's attached to like a joystick arcade thing. Like there's so many cool potential things you could do with this effect. I love this effect. Oh, it's so cool. There you go. At some point we're going to have party parrots on here. Just kind of say that. It just has to happen. It has to happen. We'll have party parrots for sure. Good comments on the acrylic at being the secret sauce for how good this looks. Yeah, it really is. Even our seven year old Gavin, when I show him, I'm like, it's black. There's nothing. And then like, it's like, how is that possible? How is it possible that light can go through a black colored thing? Some crazy optics going on here. And Yiannian, the discord saying battleship game. Ooh, yeah. Or a light break style of game. That'd be cool. Just kind of paint your own thing. That'd be really cool. A light break. Yeah, this is why I want to like give it out like now. So I want folks to write code for it. Sweet. And that's what we're prototype. Well, there's more stuff. Pedro's got stuff, we still have a lot of time. So that's great. Okay, cool. So continuing or finishing up the little guardian robot. This is a little shoulder companion robot that Filamar wanted. They see a lot of these going out and just did some paint work on this little guy. I still left the, I'm still shooting like the part shot. So I forgot to put the diffuser back on there. It's still. Just the time for Easter folks. He's an egg bot. Right? That was perfect. So super simple little guy here. There's a servo inside, a little neopixel ring to give his little eye that glowing miss. You can kind of see the little swirls that are going on in there. Everything is snap fit together. So all of the components. Showed this off last week. But here's the guy with the light bow charger now inside there. So nice little screw that's on the bottom there that is charging the battery, which is on the inside of here. Got a little switch on here to turn the circuit on and off and an it's a bit see. NRF 82840. So you can connect over Bluetooth and maybe trigger some different movements or some trigger some different animations. Yeah. So the whole guy is being put together with these lovely little Pico mullics connectors. So you can disassemble this or for assembly it's a lot more easier to connect all those not have everything soldered up to the board. You can easily put that together. Nice little custom horn on here. That's controlling the whole head. And you can see in here these little, it locks into these little snaps there. Grabbers. Little grabbers. And that's pretty much it. Nice. It's a good simple bot with some snap fit pieces, some magnets. Here's how you put it on your shoulder. So just attach it to your shoulder with one of these little metal things that are usually sold with a little shoulder pump in it. You can get soldered like from the Disney theme parks. There's like the Pandora banshees that you can get. I think that's what they just released a whole bunch more to for the little plushies. There's some Star Wars creatures as well from Galaxy's Edge. But yeah, it's just a piece of metal with a rubber ring in here. Maybe you can buy that separately. I look so future with that on. Cyberfunk now. So of course everything was painted with this lovely acrylic gold paint. Wanted to avoid having to have it dual extrude just so everybody would be able to print one of these guys. And then all the legs just snapped together and a nice little floppy action. And that is next week's project. I totally have some like Naruto shinobi vibes here with this faceplate, this headplate here. Very cool. This is so awesome. Great little companion bot. Rechargeable with the light poly battery. That's great. Yeah, and Bluetooth. It's all running circuit pythons. Some super simple demo code. We wanna ask the dragon for some help here to get some more random movements and triggering some different things via the Blue Flute app. So we can do some Bluetooth control. Yep, and as you just saw there, it all snapped this together. And a nice little simple assembly for this guy. It was only like- With the feather fit in here? I don't know. Maybe. Yeah, I mean, I'd have to make it bigger. Oh, very often. The entire body. Yeah, the entire body was scaled to just the itsy-bitsy. Yeah, all right. Well, when you're looking at smallness, that's probably what we should recommend is the itsy-bitsy. I just, the commenter in my head is like, why don't you use a feather? Because that's- I didn't design it for that. That was a Lamar suggestion for the itsy-bitsy. Yeah, it's like itsy-bitsy. Yeah. Okay, wonderful. And these are printed snap fit feet. Good job on the little trim here for painting. That's great. Mm-hmm. Cool. Egg bomb. That's the Armand- Sell the Age of Calamity. Armand VP is saying, yeah, same the little baby group ones at Disney Springs. Oh yeah, the baby group one. So cute. Then a snake game would be easy for the Matrix. Yeah, snake game would be super cool. Pong, snake, asteroid. It's 16 by 16, so you're a little limited, but yeah, snake would totally work well in that small pixel format. And then, certainly Bruce is saying that the next best displayed price was 11 bucks for a single sheet, but that would take over a month from China, Hong Kong, Taiwan. Yeah, I forgot to mention that. The Matrix I got from Amazon was next day delivery. Yeah. It's like a lot. It's a lot. 20 bucks. Next day? Two. Ha ha ha, a lot of two. Because I buy them from A to F, but we're out of stock. I think when Lamar kind of looks at the manufacturer, she might be like, wait a minute, the price has changed. Like, I can cut the price now. That'd be great. So hopefully that happens. All right, cool. So that's what we're prototyping. Well, there's another thing. We have time, right? I'll give you five minutes. It's the Cyberdeck for the Raspberry Pi. We got our hands on the Cyberdeck. Well, really, the Pi 400. So this is the Pi 400. And this is the Cyberdeck for the Raspberry Pi. We have two versions of it. One for a bonnet for the bonnets and one for a hat. Those are the full-size hat. So what I have here is the, well, how does it connect and how does it work, blah, blah, blah. So this thing has this 2x20, so 40-pin thingy. And then you plug accessories into the Pi here. This is for power. You're supposed to give it like five-volt USB-C three amps or whatever. And then you have a couple of USB options and a cat five. And then there's your, what do you call it? Your Hesty card. So it's designed with this jaunty angled header thing. That Lamar had custom made. And it keys into the thing there. So I designed this little bracket because I was like, well, I need to fit a sensor on it. So I came up with this kind of modular, come on, mount bracket that has these slots here, two of them so you can mount whatever you want to it. So that's really cool. It's not designed for a custom board or anything. It's meant to be modular. And it takes like half an hour to 3D print. So to make this portable, we have the power boost 1000 seat and I have that wired up to this little USB-C connector here. And then I have here is the Stemma sensor. Oh no, I need the Stemma cable. I guess I'll have to steal it. You remember that Adabrit fruit box that we got? Pedro, we never took it out because I needed like, I need a bigger cable now. Do you want to grab it for me? It's in the other garage. No, just on the photo table, I think there's more of these Stemma cables. So yeah, I need a bigger, I'm running out of Stemma cables. So what's great about the Cyberdeck is that it has Stemma connectors built into it. So I can plug and play Stemma sensors to a Raspberry Pi and I can use the libraries for Blinka, that's the wrapper for Linux hardware. Thank you so much. So now I can connect this, literally plug and play no soldering here and then just plug this in the right way, right here. Okay, so now our sensor is connected, brilliant. On-off switch will turn on the power boost. It gives me, so I'm using a 2200 LiPo battery. It's only a 3.7 volt battery, but because of the power boost, it's gonna boost that up to five volts, two amps I think. And it's turning on right now. I have killed the battery, so now I need to, this one, this is the micro cable. So I will plug this in. What's cool about the power boost that it lets you know when the battery is low because I had the little, the red LED was telling me, so now it's charging it through my computer and hopefully this starts up here so we can show the demo. Is it working? Welcome to Raspberry Pi. This is work. It's a comment Susan is saying that she needs that cyberdeck rack. It's pretty cool, right? There was an issue maybe with power when I first started it up. It's hard to tell if it's like going or not. There's like an A, I think that's activity, but I don't see any activity. Maybe the SD card came out. I know that happened to me once. All right, I'm gonna have to do something that's not so kosher, but turn it off and then turn it back on. I really want to show you the heat thermal camera demo because we have some demo code for the AMG8833, which is a IR thermal camera sensor that plugs in through this demo QT. Give it a second. It's doing something. I saw the power LED blink. It's running the latest, you know, OS, Raspbian, whatever. And real quick, I got a question from Mark asking, hat versus bonnet, what's the difference? Yeah, the difference is just format. So the bonnet is just slightly smaller, right? So it's shorter. So it's fit on like a pie zero. Yeah, it would fit on a, well, no, it's like the pie bonnet is for the bonnet accessories. So any OLEDs that are small, that are shorter, this is a full-size hat. So that's how you can tell it's a full-size hat. Like this is like the footprint for that. So that's really the difference. It's just a format thing. I think it's loading. I'm not sure what's going on here. I'm SSH-ing into it to see if it's showing up or not. I think I might have corrupted it or something. I don't know. Too excited that I just tried it. Yeah, it's not, I'm going. Yeah, I don't know what to tell you. I think it's just live demos. Yeah, for sure it's a live demo. You know what? I think I jammed this in wrong. Now definitely you turn it off. All right, so you are able to plug that in, even though it's keyed, you are able to plug that in wrong. I don't, maybe? No, I don't think I plugged it in wrong. Cause it is keyed, like you said. The screen's showing up white though. That's different. Yeah, it is. It's happening, folks. You guys spoke too soon. Let me see if I, oh, there it is. All right, holy crap. Well, you know, Raspberry Pi, right? So it does have a touch screen. You got to be kind of careful with it. It's running the mirror frame buffer copy. Like if you know Pi TFT, you'll know the frame buffer copy mode. All right, so what I'll do is just type in CD-MG8833. That's the folder I want to go to. Then I'll run the Python script so I type in in Python code.pi and I'm gonna run it. So this is the demo code that is a part of the AMG8833 learn guide. So you can grab this demo code right now, copy and paste into your Pi script and get this running right away. So that's the demo I wanted to show you. I am low on a battery, but let's see what happens when I disconnect. There we go. Holy moly. We are now portable. So there is the Pi 400 running off a little battery. And there's the sensor there. There's just a hot computer that you're looking at. Y'all are so hot. Look at that. So cool. It doesn't quite fit in my arm, you know? But off we go into the wasteland. Very cool. I needed something to do like in an hour. I designed it in one hour and then I printed it in half an hour, which is what? Yeah, and then a reminder from KY Chem class. Don't do that with the power on the Pi. I'm so sorry. Yeah, we know. I committed so many atrocities today. But hey, here we go. You ready to jump into the cyber deck? So here's the cyber deck. Lamar, I asked Lamar if she had a technical drawing for the headers. So she just sent me a PDF and I was like, this is great. So I modeled the headers because they're custom made. Nobody makes these. Lamar is the only one who wanted these. So I figured I'd model and I was able to make it with just two sketches. So that really inspires me to make a layer by layer tutorial on how I did that. So if folks want to make their own custom headers and stuff, they can be helpful. How to use patterns and sketches and really break it down. Like how do you make this with the least amount of steps and work inside of Fusion 360? And beautiful artwork silkscreen from Philip Berges. You can see, what's the dolphin's name? Oh, I forgot. Timmy, Johnny, something. But that's Johnny. Mnemonic. Keanu Reeves before The Matrix. So that's pretty crazy. And you know, that's the look I make when I get a data sheet that's a JPEG. I'm just like, my eyes, you know. But yeah, I'll release this model at some point. All right. And that is in prototyping. I had a couple more mounts. I think you want to add some little things so that when you push down on this. Yeah, that's right. You saw that it has a lot of wiggle there. It's not killing the power, but that just doesn't feel right. So we can add a little kind of wedge, a little guide that will just make it so it's a tighter fitting. Yeah. Yeah. Jones. His name's Jones. Jones, the dolphin. Sorry about that. Jones, the dolphin. I should remember. Yeah, also pick up this awesome AMG8833. This will work with feathers, too, because we're running the same library. So that's really cool. You can run this on a feather for sure. And it'll boot up, incidentally, unlike the pie, because you know, Linux, right? So that's cool. I think we have those in stock. We just type in AMG. There it is. There's the sensor. And in the demo code, we have it in the product page. We have it running with the pie as well. But you can run it off of an Arduino or a circuit pie on board. Very, very cool update to the AMG8833 grid eye. Very cool board. It's pricey, because look what it's doing. It's a heat sensor camera. Yeah. These things are like $100. We were finally able to get these back in stock after they were out for a while due to the pandemic. And they're in stock. That's great. Cool. Happy with my demo, my predator view demo. All right, well, with that, suggesting the 7-inch display to go onto the cyber deck. Yeah, right. And then there we go. From Freddy, Air Freddy. About the matrix. Yes, you can chain them together. That's true. On the back. You can chain two together. Yeah, four of them. Four of them, more. Six of them. Mr. William Bruce is getting six of those to make a Linux cube. That's 1,020. He's doing the eBay route. Oh, OK. That's great. That's actually what you wanted to do with those. Yeah, make a cube. But I made one. I was like, ah, that's simple. Like, after coming off of the Pico MIDI controller, I just want to do an easy project when it doesn't take two months. And then K-Boy, Ken Plass is saying, yeah, put it on your arm like a Pip-Boy. Yeah. How funny, I don't have the link to that. To the Pip-Boy. Pip-Boy, the Pip-Boy 4000. Y'all should check out Zach Friedman's Pi 400 build. He has, like, handles and, like, a HUD that's removable with magnets. Check out this giant Pip-Boy 2000 MK1 replica. Yeah, here's a more. It's huge. TinkerCAD, did you post it? Oh, it's on the YouTube. I see it. There it is. Also, Zach Friedman did a cool one. But this one's, like, um. You can't really tell that's a Pi in there. That reminds me of, like, a Tormach. Is it a Tormach? Yeah, they just asked. If you haven't seen the Zach Friedman Cyberdeck build, you should check it out. At least post links to your favorite one. Yeah, so that's cool. Do I post this on the Discord? Oh, I already did. OK, wonderful. And it's going out as a blog post tomorrow. Wonderful. Yeah, I see it there. All right, well, let's look at Community Makes this week. Yeah, since we're already looking at these awesome makes. Yeah, so on Tuesdays, we do a little time-lapse. And this was a print-in-place piece here. So let's check it out. Yeah, this is the Articulating Sandworm from Dune. It's designed by a dark, or rather, remixed by dark kumquat. Yeah. So this was originally the Articulating Slug. So of course, it had to be themed out to the awesome Dume Sandworm, hitting theaters, I think, sometime later this year, next year. Whoa. One of PT's favorite sci-fi pieces. Franchise. Is this a franchise? I don't know. This is a little guy. What's so cool about it, it is all print-in-place and articulates. You can kind of see how the inside of the joints are printed from the time-lapse there. And it is so frickin' flexible. It's so cool. I want a croissant. I know, right? It's where it looks like a croissant there. We're using this shiny copper. So you get that nice, shiny, not iridescent, just shiny metal looking PLA look to that. And excellent tolerance testing for your printers. You can see, can you print all of these sections without it fusing together? Even a little tail, too. It's so cool. A baby sandworm. So let's take a look at it on Thingiverse. This is where we grabbed it. It's a remix. It looks like it was sanded here. That looks cool. Yeah, yeah, yeah. Sanded down. Yeah, look at some of the reference images. And all of them came up red, I guess, just because of the landscape inside of Dune. It's all red and sandy. So here, if you like slugs more, you can download the original slug by Isaya. Different colors. Super cool printed place. Getting some Pangolian vibes here. But there you go. He's got a potato. Eek, eek, eek. You usually find slugs. Yeah, it's very cool. That is this week's community make. And then we have some more from the community. These get sent to us via Thingiverse Make Alerts. So this is a remix of our IoT Gmail box project. So it uses a Huzzah feather. And it connects to Adafruit I.O. and uses if this than that to give you a, it has a built-in servo. So the flag will shoot up, letting you know it's a 3D printed mailbox. The flag lets you know you got an email. Inside the mailbox is the board. So Thingiverse use your Wardon. Remix this to fit a, I think, an ESP-style board with a perma-proto thingy and a speaker here. So really, really cool. So now it has audio. It has some extra things in the base. Actually, he did the whole base as well. So this is a really fantastic remix. Like made it really fully featured with sound effects. But yeah, you can put this together with any microcontroller. That's what we like to see. So adding to it with the speaker. And I think that's an SD card holder. I didn't even notice that. So it's doing some data logging as well. There's a wiring diagram and all the STLs are here as well. Super awesome build. Making this again would be really cool too with a feather. I think ours used the feather. It had built-in lipocharging and all that. But hey, you can remix it and have some sound effects now. Very, very cool. And I like the stand for it because it really finishes the whole look. Here's what it looks like, Pedro. Like they're inside the base. Yeah, right? It's super, super legit. On the back is the speaker. And in the base is the little micro USB. That was the cutest micro USB connector there. Super cool. Very awesome from, thank you, Wardon. Wardon, we put that together. Couple more real quick. This is a Lantern, a 3D printed Lantern using the Circuit Playground Express. Circuit Playground is a really awesome board that has lots of built-in sensors and built-in new pixels. And if this image loads, we can get a look at this. It's, there it is. I didn't know you could have gifts in, and they sometimes work. They sometimes work. So this shows you how you can really make some awesome stellar lighting effects, especially with the LED animation library for Circuit Python. That'll totally run on the Circuit Playground Express. And this is a remix, I think, that we did of this Lantern. Lantern was originally designed by, I forget her name, but it's a designer lady who released it and then we just fitted, we designed a bottom piece that fits to it. There it is. And Songya, Wardu, is the original designer of the lamp-based piece, and then we just made the bottom fit. Check out all of Songya's designs there. They're incredible. They're gothy and so intricate. Yeah, this could work for whatever. Halloween or some other thing. But yeah, it's a really, really cool. 3D printing custom lights is so great. Such a fun thing. All right, and then the last one, close to the last one, this is a remix of the Raspberry Pi Octoprint case. So this now fits the Pi 4, which you'll notice the Pi 2. You need to print this. The top piece still works. I need to update everything to the Pi 4. So this is the original, this is one of our most popular projects because it's such a useful thing. It uses the Pi, Pi TFT. Yeah, we need to redo it. It has an open hinge, but yeah, it was designed for what? A Pi 2. A Pi 2, yeah. And there we're on Pi 4. So shout out to... Yeah, there's lots of updates that we needed to make. A Sunic, who remixed this to fit the right portholes for the updated USB-C and HDMI connectors on that Pi 4. And another snap together project that doesn't use screws, I think. So that's a cool little remixed. Except when the little snubs break off. Yeah, sorry. And then the last one, of course, it wouldn't be Q&A makes without a unicorn horn. Cool. So they are the designers of the unicorn horn. And think of where she's your crawl, posted this up, blurred their face nice. And then it says gaming headset unicorn. Printed on a BTU B1 printer. And now, yeah, it's got the color changing LEDs. Very cool. I always enjoy seeing the unicorn. And like, yeah. I think like two weeks ago it was on a horse. It was on a horse, yeah. It was like, I think it was on a cat, a dog. Yeah, look at all the unicorn horns that we've made. The folks have made. It's quite fun. Lots of different ideas. Yeah, a cat. Never gets old. Yeah, it doesn't. And I have a tutorial on how to design what I think is one of the nicest. Was that one in 1, 2, 3D, though? No, it's in Fusion. I did one in Maya and then like four years later I did it in Fusion. I remember asking one of the folks on the Fusion team like, how do you do that? And they were just like, you know, I don't know. And like, I figured it out. So I feel good about that. So there you go. That's this week's community makes. Thank you everybody for posting your community makes. Awesome, awesome prints guys. Then we had some comments in the Discord on what CAD packages to use. That's some suggestions on using Tinkercad. And then FreeCAD, my mustache in there. Yeah, if you're filling up to it for Fusion 360 there are a ton of layer by layer tutorials that Noah's worked on if you want to get started on that. Yeah, shout out to folks who saw my latest one on adding parts and working with external components. It could be a very, very dry and boring topic but it's like one of the most important pieces that took me a very long time to learn after like fighting with Fusion for so long. So it really covers like some of the kind of basic essentials of working with components and positioning them via joints and sketches. So, and then of course parametrically driven with user parameters so you can scale it and your parts will kind of grow with changes. After just doing like what 300 guides, you're like, man, I really hate making changes and then you spend more time. That's like the whole story about Circuit by I thought. I was like, oh man, I feel something easier to program. Let's spend years developing Circuit by I thought. So yeah, you can get the parts from our GitHub repository. We always try to have a link down there in the description so folks wanna grab our 3D models of these parts so you can use them in whatever CAD package. All right, I think that's gonna do it for this episode. We are over by like five minutes I think our lunch is getting cold. That's okay, we'll heat it up. We do it for you. Thank you folks for showing up. We're gonna be on the show and tell. We're not hosting this week, but we'll host, you know, I think next month. Next month, yeah. We're doing it at the end of each month. So, buddy, make sure you all check out the Discord for all the links so you can join if you have something cool project that you're working on or any retro tech or anything else. Yeah, yeah. That's a tech-related, it's all game. And then right after that is Ask an Engineer at 8 p.m., full hour with Mark Fill on all of the latest going on with products, make your community and news and more. Oh, top secret as well. Top secret, yeah. We're gonna see some more keyboard stuff. Oh yeah, it's coming out. All right, folks in the Discord, we'll see you guys later tonight for everybody else. Remember to make a great day. Have a great one, see you tonight. Bye.
