 Hello and welcome to the Adafruit show and tell. I'm your host this evening, Liz, with my co-host, Erin St. Blaine. Hello everybody. Hey, so first we're going to kick things off with folks from Adafruit and then we'll hear from folks in the community. And if you are in the community and you would like to share your project, you can join the StreamYard link that's in the Adafruit Discord on the live broadcast channel and that's adafruit.it-discord. So first let's see, Erin, what you've been working on. Well, I am working on a fun little project which is Totoro themed. This is an umbrella stand. I have a little 3D printed Totoro down here and a Totoro sticker on there. The cool thing about this umbrella stand, it's got some neopixels in the base and it is running a Raspberry Pi Pico W and let me see if I can get it plugged in here. The Pico W is going to talk to Wi-Fi. As soon as it connects to the Wi-Fi, it's going to come on in blue as well. And then it's going to check the weather. It's checking the weather with an online API and if it's raining or it's going to rain in the next six hours or so, then oh, he's going to turn a little green. Obviously, I'm in California. It's not going to rain probably for another eight months here, but I've got it set to 11. So in London, it's going to rain sometime in the next six hours. So this is just a cool little project. If it's not going to rain, he'll be off. If it is going to rain, he's on. So it's just super simple. And it just reminds you to bring your umbrella. Excellent. And excellent call, making that the, yeah, sorry, go ahead. I'm working on a tutorial for this guy. It's probably going to be up within the next day or two on the Aideford Learn System. So it just seems like a really useful little project. Yeah. And I love that you themed out with Totoro. That's great. Yeah. He cares. Totoro cares. He doesn't want me getting wet. Yeah. All right. Who would you like to go to next? Why don't we talk to JP? Okay. Hey, how you doing? So I am excited to show progress that I've made on a project that started quite a while ago and took a break from for various reasons. It is the L cars project, which is the computer display system from the Star Trek universe. And this most recent episode of Star Trek Picard reintroduced the enterprise. So this is why I actually have this thing, which I'm just going to pull out. This is the prop from the show, which doesn't look like much when it's not back lit. But this was a sample from the show. I have a friend who worked on the show and he got this, was given it. He didn't steal or anything, I think. And he asked if I could make a display for him so that he could actually backlight this thing and maybe even animate it some. So I've been working on, you can see back here in LED matrix. And I have one of our matrix portals plugged into it providing some animation and some buttons to choose whether you're animating or still or turning it off altogether. And so I'm working on some laser cut layers to embed this in. And then I'm also going to be putting a mahogany veneer over it to match some of the stylings on the show where you have this beautiful warm dark wood color with the high tech display on it. So that I'll probably actually be cutting that tonight and able to show it on the show tomorrow. But what I'm going to do, I'm going to cut this overhead light that's glaring off of there. And I'm just going to plug in the power on my matrix and it'll boot up here. And let's see, I got it a little out of alignment. There we go. So you'll see a little bit of flickering on the camera. It's not there in real life. And it looks really, really beautiful. So you can see here, the way these worked on the show originally when they were a practical effect. And then later when they went digital is essentially lighting or not lighting information that's kind of always there. I don't think until they later got into doing these as digital displays did they actually update any information. It was just kind of whatever is on there is going to blink on or off. I don't think the colors even changed. So this is mimicking that old enterprise styling here. You probably saw when I had the display off there, I have some little light blockers to prevent bleeding. So as much as possible, even though it's a pretty thin layer of blocking, and it works pretty well. We got a little softness on some edges, but I think it's really charming looking. So I'm just working on that and happy to get this out into the world and to give it to back to my friend Ryan so he can proudly display this and and it's exciting for the people in Star Trek world I think to see the enterprise back so that is what I'm working on come on the show tomorrow I'll be on at one o'clock Pacific time four o'clock Eastern time working on this in the workshop. It's great. It's really fantastic. Thank you. Yeah, it's been cool to see your progress on this. It's been a long it's been a long journey on this. I had to step away from it at various points and and then I got excited about it recently, especially because the episode was was coming out to kind of re jump into the design into the into the rhino and grasshopper files where it started working on it and finally some good solutions for essentially keeping the thing steady and stable. I'm going to have, I don't think I'm showing it here yet, but I'm going to have some heat set inserts in the top panel so the screws will come up from the bottom but then the veneer layer has that 3M adhesive back that will go over the top and just about two millimeters of overlap with the real panel there so it'll secure it but you won't see any screws or anything. That's my plan. Very classy. Awesome. Thanks so much JP. Thanks guys. Thanks. All right. Next, let's hear from paint your dragon Phil B. Hi. How's it going? It goes well. My favorite Adafruit board is like whatever I just got, you know, whatever the newest thing in the shop is that I just got and I don't have the USB HID one yet. So right now it's the it's the feather RP 2040 DVI. Yes. And we have some demos for this, you know, it was just like draw some circles or draw some triangles or whatever it was very dull and the more wanted me to do some old screen savers. So that library, the Pico DVI library now has an extra set of examples with the flying toasters and an aquarium and then one I wanted to do I got John Park to help with this. It's doing that sort of a max headroom animation. That's awesome. So that's that's one of one of the demos that's there. And getting these to compile is you got there's some fussy settings but I just put you have two files there. So if somebody just wants to run one of these, one of these screensaver inspired programs it's it's drag and drop simple you don't have to get super involved there. But anyway, wanted to show that I had an idea also because these these monitors are getting like so light now would be just remove the foreground sprite just have the cube back there and put it on a backpack as a as a thing I'd use a bigger but just a silly Halloween idea maybe. That's awesome. And the glitching is just perfect with JP like super good. And I thank you for your work with the Pico DVI for Arduino I'm working on a video synth right now with it. Excellent. Excellent. More with the basic shapes not the not the fun. That was that was the original plan for it was video since stuff. I went more like kind of vaporwave theme so that'll be coming soon but your work on that made it really easy to get up and running with your guide so. Excellent. And it looks like we have a question from discord what monitor is that. This is the GKD why and they're these portable portable HDMI monitors you can get now that just come with a little folio sleeve and way next to nothing it's you know like the let the iPad stands have you know you fold it around and then it stands up. Yeah, it kind of works like that. So it's not a normal desktop monitor it's something something you would tote with you. Nice and thin. Awesome. Well thanks so much Phil B and folks and check out your updated guide. Alrighty. Alright, thank you. Next let's go to Scott. Hello. Let's let's keep on this feather DVI train huh. What I've been using for testing is this smaller seven inch monitor. I just picked it up off Amazon they're super handy. It's powered by USB and just has an HDMI port but I don't currently have that on because one of the other cool things about having DVI support is that you can use HDMI capture stuff. So if you share my screen here. You can see a webcam window here open and it's capturing the second webcam essentially so you can see me. And then this is what's being output from circuit Python on the feather DVI so if I control see here. You'll see that now we're seeing the terminal output console output running and one thing I wanted to point out here is I've just adjusted it a little bit. So we made that left hand column actually have characters in it. And today I was working I made it so that it aligns to the right hand edge so there's a few pixels on the left hand edge. They give you just a bit of padding in case you have like somebody asked about a pipe portal issue where they quite portal case covered it. So this helps that and then also it'll being right aligns means that the status bars aligned as well. Like the columns for all the characters are matching up now which is cool. But if I just hit control D you'll see that I have a turtle demo going and it's running from circuit Python over DVI. This is the 8 bit color which is like 320 by 240 that gets pixel doubled. So the signal is is 640 by 480. So that's coming PR is out today and that includes feather DVI support and also adds support for Pico DVI to Pico and Pico W as well. So you can instantiate it if you have one of those like things that Pico plugs into that has the DVI connector on it. It should work there too. It's quite the trick to get enough memory allocated but you can do it. So check that out, give it a try. Thanks to Mark on Discord for testing it and helping me find some color issues. But yeah, that's where I'm at. Awesome. I'm super excited to play with this. I've really enjoyed playing with Arduino but to be honest I prefer programming circuit pythons would be cool to see what we can do with that. Yeah, so everything working on that. Everything in Display.io should just work. Basically, Display.io will render to the frame buffer that then gets output for DVI. So hopefully it will just work. Awesome. Awesome. Thanks so much Scott. Thanks. Have a good night. And speaking of Mark, we're going to start hearing from folks in the community and here he is. Hello, how are you? Hi, I'm doing great. Yeah. Good, good. So before I show what I'm working on with DVI because that seems to be a theme, sneak peek for last week that just showed up on my doorstep today. Oh, excellent. I was too tired from work to just trust myself soldering on a circuit board. Yeah, so Scott gave me a preview of the DVI stuff a couple of days ago from his stream, which coincidentally was right when a DVI board showed up on my step. And I missed Ask Engineer last week and heard them talking about, well, let's see if we can get animated GIFs running on this. Well, it is now running. Woo. I'm using the same trick as Scott using an HDMI capture device. But in addition, the big issue that I was running into was memory with the GIFs and the frame buffer for DVI. So I spent some time and it actually was easier than I thought it was and added in pellet support for GIF IO or for the on-disk GIF. So now this takes about half the memory. So this is 320 by 240 resolution. So it's taking up the full thing. It's not scaled up and still has memory left on the RP2040 for whatever else you're doing. Oh, that's great. And this is running. This isn't sending the pixels directly to the display. This is actually display IO showing that. So it's actually running fairly fast just on its own. That's super cool, yeah. Overall, really happy I would turn it on. And a huge thanks to Scott for getting all this in. Excellent, yeah. It's awesome. We already got the GIFs on there. I'm really looking forward to seeing what folks do once this is all merged in and everything. For sure, yeah. The pellet support is also in a PR. I've got a couple changes to do on it. But hopefully this weekend it'll be out. Nice, yeah. Awesome. Well, thanks so much, Mark. Great job. What? Yeah. Good night. Let's go to DigiWiz. Hi. Hi. This thing I've been working on is the 3D printed version of the portal gun from the Portal egg games. Oh, wow. Yeah. And at the harsh of this RN, it's got to fucking shake it to get it to work because the lights have been on the fritz. Okay. It's okay. Live demos. Yeah. There you go. Nice. Can you turn it sideways so we can see? Yeah. I feel like it's fantastic. Yeah. The blue does not work right now. So is this 3D printed or foam work? It's 3D printed. It's a file I got off of. Thingiverse. Excellent. Nice. And then is it NeoPixels in there? Yeah, it's for the two bits, two NeoPixels sticks. For the front, it's a NeoPixel ring. And then for the top part, it's a NeoPixel jewel. Sweet. And Arduino, MicroPython? It's an Arduino. I tried to use Feather M4 Express, but I couldn't get the 3.3 volt stuff to work properly. Yeah. Fair. Cool. Well, great job. That's a really cool build. Yeah. Yeah. So thanks for coming by. And look forward to if you make more props or add more to it, be sure to come by and show us. Yeah. I'm currently making some Ghostbusters stuff for a Comic-Con that's coming up. This is going to be super popular. Yeah. Yeah. Yeah. Definitely come by and show us that. Yeah. Thanks so much. Yeah. Thank you. No problem. Next, let's go to Todd Butt. Actually, Todd Butt, one second. I see Kevin from DigiKey is here. And it looks like he is live on the event floor. I am. Can you hear me? Yes. Yeah. It's probably pretty loud in here, but I am live. I am in Houston at the World Rich Robotics Competition. So DigiKey has a booth set up here. And we're showing a bunch of really cool data products as well as we're taking pictures and making buttons for people right on the spot. But the energy here with all of these young students and future engineers is just absolutely incredible. I'm going to see if I can flip my camera around really quick. Okay. I'm going to show you a little bit more of our booth. Does that work? Okay. Yes. Yep. Seeing it. Okay. So here's a little bit at our booth. We have this really cool robot that was completely 3D printed. There's nothing that isn't 3D printed. And one of our engineers made this. And you can see a couple of NeoTrailers boards over a crowd favorite at any show. Everything that has bright lights and makes noise. So NeoTrailers is a home run. If we move over this way. We have our A-Prood ARC reactor that actually, this is a project I built. It's using the blue-proof circuit playground express with an extra set of new pixels around the outside. So you can control it with your phone and change the colors. And there's actually audio in and out. So it's pretty cool. The A-Prood glasses. The LED glasses with the... Yeah, we just have it set up with all those on it. And it sounds like one team is doing really well here. We got loud. And second playground is just a ground machine set up on it. So that is just kind of a quick overview. We're displaying some videos. We have to skateboard with LEDs on it. A-Prood displays on... I don't remember. It's a 16 by 32 matrix display. I think up there. This is make a digit key. And then this is the other thing we're doing is we're making buttons live for people. We kind of take a picture and I think we're done. We're button-made right here. Oh, cool. That's awesome. Looks like a really fun setup. Literally, it really is. And like I said, the energy here with all these students. You can just tell that a lot of these kids are in their element. Talking about their robots. Competing with their robots. I'm really excited for tomorrow. Today is mostly practice day for all of these robots and all these teams. And then tomorrow is competition day. So, you know... Sweet. So I keep switching my camera. But just seeing the different design some of these kids have. They all have a different way to go out the project. David wants me to show our other robot. If you recognize the face on it. He's a pretty printed Kevin's skull, which they thought would be pretty funny to make. Excellent. But that's what I got for tonight. So I just thought I'd jump in and show you guys what we have to offer. Awesome. Thanks so much. It looks really fun. And are you folks like doing any blogging or having any post on socials about stuff? You see right behind me. Other side. This side. That is our social media supervisor right there. So she is doing all the social media stuff live on site. Excellent. All right. Thanks for broadcasting live from the show floor. You're very welcome. Thanks for having me on. You guys have a great rest of your Wednesday. Thanks. You too. Thanks. Bye. All right. Now that was really cool. And now we're going to hear from Todd Bot. Who I think. Hey, how you doing? So to continue the Pico DVI stuff. Let me turn on my picture and picture here. So this is the Pico DVI. It is a little video synth. Let me lower this. Raise this up a little bit maybe. So here's a little MIDI controller. And with this I can turn the hue of little triangles here. I can also change the rate of the triangles. And this moves it around. And then you can compose with it. This is all on Arduino. There's more triangles. This is available on my little Pico DVI experiments GitHub, which I'll link to in the discord. But yeah, I said it's a thank you paint your dragon for wrapping up the Pico DVI library into something really usable in Arduino. Yes, definitely. It makes it so awesome. You can just use all the Aida for GFX library stuff. It's super cool. Yes. So good. That's awesome. Anyway, thanks. Bye. Have a good one. All right. And last but not least, we're going to have DJ Devin put us out. Hello. Can you hear me? Yes. How's it going? Okay. Well, I didn't know that DigiQ was going to have a tank on there. I have a little tank. It's DVI night and tank night. Yep. So I had to modify it, strap on this massive battery because the little battery that I had ran out right as the show began. So I just, I was literally as, as the show was going on, I was wrapping everything we kept on tape just trying to get the work. I've been there. So this actually uses an adafruit battery with a power boost to power the five volt FPV camera. So this has a little FPV camera on it. Nice. Oh, and you can. Okay. Nice. And one of the cool things is because it's a tank, the turret actually moves so the FPV camera can go back and forth. And I'm trying to build this as a tiny little pipe inspection bot to take a look inside my sewers. Because in Florida, not, not most, but some, some of the homes are on slabs of concrete. So the only way to inspect your pipes is to like get a camera down there and I have choice words for the plumbers in the area that try to charge me $500 to put a camera down there. So this costs me about $100 to build and I'm going to tank it. Yeah. So there you go. That's my project. Excellent. And are there any alligators or teenage Ninja Turtles? There might be a three headed turtle in the area. I'm not sure. There's actually a two headed alligator. That one is down a little south near Fort Lauderdale. It lives in a pond. That's a, that's a thing. Yeah. Oh, I was not expecting that. All right. That's Florida. That's our, that's our motto. Two headed alligators. No, I wasn't expecting that. Okay. We weren't either. Well, awesome. Thank you so much, TJ. Okay. I was, I was like, what you're working on. Thanks. Have a good one. All right. And that's going to do it for our show and tell. Thank you, Aaron for co-hosting. Thanks so much. And thank you. Yeah. And thanks everyone for showing your projects in about five minutes. Stay right here. Ask engineer will be on with PT and Lamar. But until next week, have a good night. Thanks folks.
