 All right, Lady Aida, what is this? Hello, everybody, and welcome to Show and Tell. It's me, Lady Aida, with me, Mr. Lady Aida, on camera control. We're broadcasting live here from downtown Manhattan home of Adafruit in New York City and the rest of New York City, which is not as nearly as interesting as Adafruit. But right now, we have a most interesting half an hour. We have 30 minutes of all the people in the community making stuff, sharing stuff, showing stuff. It's Show and Tell. I'm going to kick it off with Kevin from DigiKey, and then we'll call on other people to be out of here at 755. Take two, three minutes when we call on you to show off your things. Start it off, Kevin. Hey, how's everybody doing? Hello. Good. So a quick project that I have working on. I got my Feather RP2040, which I'm pretty excited about. And for some reason, I couldn't get my 14-year-old daughter to come on Show and Tell tonight. But we're working on a project for her for school, trying to teach her how to do circuit Python programming. And it's a solar system. So it's a work in progress. It's not real pretty yet. But I have just a little test code in here. So it just spins around, and the Earth spins with the moon around it. Of course, it'll keep going all the way around. But just for testing, I only have it going back and forth. That looks cool. Good idea. We're doing some RP2040 robotics projects with Cricut as well, because the chip came out. And we have tons of projects, keyboards, obviously, because people make keyboards. But the thing that we built around the Feather ecosystem was a bunch of robotics and stuff. And now that we have a Feather RP2040, we can do robotic stuff. So stay tuned for that, because you might be able to do, what does it call, an orary? Orary? Orary? Or an orary? Yeah, you could do lots of things. You could have multiple things going on. Here's a fun tip. Turn the server upside down and put the Feather on the body of the orary, and that way it can spin all the way around. Oh, that's a good idea. Right, you flip the server upside down, because it can work either way. But that way, the cabling goes up, and then you can just glue the Feather onto that stick. OK, that would make a difference. And then it can rotate you. The other thing won't be able to, the moon. But that makes sense. So then it's constantly. Oh, no, it can, because it's not. That's not twisting around itself. Yeah, so that way you can have the whole thing twist constantly, I believe. I knew there was a reason I came on show and tell. Yeah, that's why I'm the engineer. I like it. I'm just sending you a bill later. I want to be sending your 14-year-old daughter a bill. Yeah, please do. I've been managing your Halloween candy for three years. She's an excellent manager. She outsourced her homework to both Digikey and Adafruit and MIT engineers. So good work on her. Can't wait to work for her one day. I'll make sure she tells her teacher. OK, no, actually, I want the most delectable treat you can have from a 14-year-old girl. She has to say I'm cool. That sounds good. I'll send you a video of her saying you're cool. Awesome. OK, we'll see you. The lifeblood. We follow you on TikTok. So we'll just look for it on TikTok. No, I'm just kidding. That sounds good. I'll make her do a TikTok. All right. You got anything else, Kevin? That's what I got for this week. All right. Out of this world. Exactly. One day I want to be reborn as your 14-year-old daughter. Sounds like a fun time. I want to try it sometime. All right. Cool. Next up, Erin. Next up, Erin. Hello. So I'm spending this winter up in the mountains and needed to make myself an LED snowboard. So that's what I've been working on this week. I've got it all finished, so I just wanted to show it off. I'm working on this tutorial this week, and ooh, there it goes. That's cool. We'll get launched next week, but I just wanted to come and show it off. So I'm using a Feather M4 Express and a prop maker wing. And I actually built the whole enclosure inside of this GoPro case. GoPro case is submersible and absolutely unbreakable, so I figured putting it on the snowboard would, you know, there's already GoPro cases out there. No, it's great. Well, don't try to design your own waterproof case. They did a great job with that. Absolutely. And the cool thing about it is that there are buttons on the case already that I can just put my, I used a little bit of thermoplastic to just stick my momentary switch in there. So I can press the button on the case, and the modes will change. Nice. It's pretty great, so I don't have to open it up when I'm in the snow and risk getting my electronics wet or anything like that. I've got a bunch of different modes on there. I've been using the LED Animations Library and Circuit Python and just layering modes on top of each other, which of course is getting a little out of hand, but that's, it's an LED snowboard. I think it's supposed to be a little bit out of hand. Yeah, yeah, totally. But the cool part is I've got a couple of modes, or one mode set up, with the accelerometer. So let's see if I can get there. No, it's not going to want to let me go there. So that it knows which edge you're on, and it will light up. Now, of course, it's not going to work for the demo, but it will light up the edge that you are currently on so that it. Oh, as you like, as you cut. As you drive down the mountain, it'll light up the left side or the right side. I can't get it to work at the moment, but. I mean, look, it's already flashing light. It's looking great. They did their live demo. Yeah, and it does, it does work. And I got it out there on the slopes. I'm going to do one more video shoot this weekend and then do some night skiing and hopefully get this launched pretty soon. But this is a really, really fun tutorial and I'm excited about this particular idea. I'd like to go for half. I like how you're, oh, you always bring a little bit of that air and magic to every project. Like the tips, the tips and tricks, that's where it's at. Absolutely. All right, good work, Erin. Thank you. One note for the people who built things out there. GoPro's an interesting company. I always thought it was neat that in the, currently still we all have these super HD phones that we can record like 4K in, but GoPro still has a place. So just because like a phone can do everything doesn't mean there isn't single serving devices or devices that you can't build yourself or make or use with your projects. Because would you put your phone there and do the same thing? Probably not. Like GoPro occupies this different space. So anyways, I like GoPro. Good work, Erin. Good stuff. All right, next step. Now I'm Pedro. They use GoPro's a lot. GoPro's, I love GoPro's. And they have spectacles. They're like the last spectacles you've ever seen. Yes. So with the folks, yeah, so we also have a Feather RP2040 project and really what we wanted to do was just highlight the StemAQT, the built-in StemAQT. So this is a little demo I put together and to kind of put it all together, we have this Lego base plate. So we added some more Lego 3D printed parts to our arsenal of existing Lego compatible plates. So the new one here is the 1.5 inch OLED. And really that was the newest, oh, and the battery thing. That's right, a little battery bit. That's cute. Yeah, because Pedro previously did the Feather one, which, hey, this is Feather and it works with all the Feathers. And what was this one is like the 0.9 inch. We have so many. There's so many different, we kind of categorize them by like, what is the... Yeah, that looks like a standard StemAQT. It's one inch by 0.7 inch, which is like 98% of QT boards fit in that size. Sometimes I have to make them a little bigger, but for the most part, I'm almost all of our sensors are that size. Yeah, which is great. So some good standardization there. And yeah, definitely check out the little video that we put together. And if you wanna get some of these Lego plates we have them on our usual places and you can search for StemA Lego and the learn system and the guide will pull up for it. So I got a little base plate here to kind of hold it up. And you can also 3D print the little Adabot there. He is indeed 3D printed. Quite cute. Quite cute, yeah. So definitely check it out. Really awesome work Lamar on the Feather. This is our favorite Feather. Yay! All the projects look great. More again. Cool stuff. And we're gonna show your Feather video tonight, the RP2040 and the speed up of a Sandworm, which is a really cool 3D printed. Good, we're doing it. Yeah. Gotta wait a year to let him lose that. All right, thanks now, Pedro. All right, next up, Melissa. Hi. Hello. I have an Apple 2C, which is like the compact version of the Apple 2P. And this one, it's having some disc issues, which I'm working on, but this was actually my mom's that she gave me to work on. So I'm trying to get it in a working condition at this point. What are you gonna run on the Apple 2? Uh, whatever software she has. Okay. I also like this little tiny monitor. Oh, that's so cute! Yeah. Oh, I just wanna take it home. It's really adorable. That is cute. All right, well, let us come back on Show and Tell as you get this going. Yeah, totally. I saw someone, they had a Mac and they were showing the Mac Paint and the Adafruit E-ink display. Somehow they were showing the same image at the same time and there was like an Arduino connected between the two. I'm just like, what is this? You sent it to me and you're like... Yeah, I don't know what it was either, but that was cool. It was like a Mac Plus and Mac Paint. And then they had that image, they guess they saved somehow, saved the image from Mac Paint and exported it from whatever format. I don't even remember what Mac Paint saves as and then changed it into like a bitmap so they could display it on a Mac tag. So... Unlike the first retro wave, like 10, 15 years ago, like as Make was doing a lot of maker fairs, that was like the first, you know, another retro wave. This round right now, there's way more resources. Like you can actually almost get anything for retro stuff. And another thing that's kind of interesting is like we're actually getting fast enough with chips and I hear people be like, oh yeah, like I bang new boss. You know what I mean? Like you can do weird shit that like we finally got to the point where it's like, oh, I can like fake peripherals and like make an ADB like local talk adapter using, you know, like an STM32. So like people are doing like weird stuff because chips are getting good enough. You know, like the mic controller is now like 20 times faster than the processor connected to. Yeah. Well, let me lay it in Apple on the next beer. Yeah. All right. All right, thanks Melissa. Yeah, thank you. All right, next up Scott and his collection of flash chips. Hello, spoiler alert. Yeah, so I just got a Digi-Key order. So thank you to Kevin and Digi-Key. And what's in the box? He packed and sent in himself. I'm sure he did. There's just a bunch of chips in here. So I've been doing a lot of flash work and I went a little crazy because flash chips are generally pretty cheap. So I just bought three of a bunch of them because I wanted to be able to test with them and just like see all of the different data for them. What you're seeing on the screen is that we have this new repo called adafruit slash nvm.toml which is my idea for how a bunch of us can just collaborate on a central location for all the settings about different flash chips. So I bootstrapped it with the settings we had in Circuit Python and I'm working on moving Circuit Python completely to that. But now I've got a whole bunch more that I could potentially add to there as well. And I just wanted to show also what I've been doing with them the way that I store them and probably what I'll do during Ask an Engineer is these aid tech boxes that I got off Amazon, they're awesome because they're little tiny boxes and so they're perfect for SMD stuff. And it turns out I went through and added a bunch more there. You can fit like LQFP 100 chips in here which is probably not perfect for like static stuff. But for me where it's like I've got one or two and I probably won't use them but maybe sometime I'll need them. Like this is way more compact than putting them in packaging. Oh, plus the link in the Discord, I'm sure people are and I want to pick up one of those, this looks handy. I like that it poses on itself for protection. Yeah, and actually, let's see. So I put stickers on them to know which one's which and I have a spreadsheet that tells me what's in every part but they actually do have a second size. So this one has like chunkier ones. Oh, that one looks good. So you can see that like over here there's the like spring things there too. So I've been really- Let's try some tea parts maybe too. Yeah, so it's been great. I just got rid of a bunch of stuff. Yeah. You know, I get more things so I have to figure out how to compact them more and more. So I'm gonna do that and then I'll have all these flash chips as a reference when I need them. And if folks are doing anything with flash chips like this and you find that you need to know like what chips support what, check out the Tommel stuff. Degetic IDs, that's what a nightmare. Every product or project, it's you have to start from the beginning. Right. Good resource. Yeah, yeah. The goal is to have just one specific place for all of it. All right, thank you Scott. Next up, we'll kick in with Liz and her star. Hello, how's it going? How are you, Liz? So I've been working on a Sailor Moon prop thing. There's a star locket in the anime and so this week I was working on the 3D printing. So this is a snap fit. The battery died like right as Joan Hill was kicking off so I'm plugging the USB right now. But this snaps fit on top there and then the top also snaps fit. So you get that locket view and then there's a spot for the speaker to mount and right here on the back, there's a spot for a switch that's gonna mount and then I was thinking about assembly and the circle playground will mount into these little kind of posts here with M3 screws and then the back you can attach the gizmo with the screws so everything's all nice. And then these allow you to press the buttons on these little cutouts here. So it was a fun Fusion 360 adventure. Looks great. I love that kind of curved bump on the top. Thanks. I actually brought the shape in by tracing the star, like a picture from the anime too. So it was like, I got that. That's why it took me a while. All right, great. Thank you. All right, next up, Alex. Hello, hey Alex, good to see you. Hey Alex, how's it going? Hey, what's up? I'm really excited because I published my first tutorial in a while, which is this ESP8266 programmer, which I also turned into in-earing because I thought it'd be stylish. It's based on- You're always like hanging out with ESP8266's and then you're like, bam, I got to program you. I know, I've made some programming jigs in the past and it looked janky as crap. It was also, it didn't just look janky. It was super janky. It's really hard to, I don't know, just so much soldering, which I love, but also I figured it would be a good idea to do a PCB of it, partly because I wanted to learn QCAD and also because I'm working on this thing called Widgetcraft, which is a project that's like a bunch of arcane tech tools that are like, if I have to have, you know, custom tools to program stuff, why not make them beautiful and culty and witchy and stuff? So it's like part of a series. And I have a little one that's plugged in here to sort of show what it's like when it's assembled. So we've got this little two by four pin header, like female header over here. We've got the FTDI boys plugged into this male header over here. And then you've got a couple of buttons on the bottom. So when you need to program it, you like push them both down. Oh, I love it. It's so cute. Oh, thanks. It's really satisfying too in a tactile way. Like, oh my God, you have no idea. So this is another one of the like Widgetcraft type ideas where this is some like old public domain images that are super cool called Carl's Emblems. And this is more like both of these are like Offspark Afterdark, which is like my favorite thing ever. It's so good. This is like copper underneath the clear solder. Yeah, it's beautiful. It looks copper-atched. Yeah, this is a great look. Oh, it kind of does, doesn't it? Yeah, it's just, it's so shiny and beautiful. And like a sneak peek, I'm like working on integrating this blue fruit guy with the NeoSensory Buzz wristband, which will be a tutorial in the next like week or two. But yeah, that's how I got it. All right, we'll keep coming back and showing the stuff. We played around with like Ouija board ideas and electronics and the last mag tag we had tarot cards. We wanted to like combine all those things. So thanks for... Wait, I think I saw that. I think I like favorited that on time. Yeah, and I think as you were looking at like, there's a lot of like electronic ghost hunter projects. And that could be kind of a cool inspiration for you. Like it's like, you like talk to the paranormal through your electronics. Cause like if you always say like an M log or RF is like black magic. It's like, what if it really was black magic? Like what if you had to like pass belts? The carvings in the edges from tarot cards, turns out they just look amazing on E-ing screens too. Yeah. I bet, yeah. With that like old school high contrast. Sounds really nice. You can make an electronic one. I feel like the robot familiar is kind of playing into the same idea where it's like, you know, starting over. Which electronics? All right, Alex, we'll keep coming back and showing more stuff. It's a thing. Cool. Let's get to see you guys. I'm working on projects again. All right. Thanks Alex. Thanks Alex. Let's go to Psy. Psy, take it away. Hey Psy, welcome back. Hi. So I designed a carrier board for my Raspberry Pi Pico to add cellular connectivity. Yeah, cool. This is my first time designing something with, I believe it's called the M.2 form factor. The cellular card comes in the M.2 form factor. And the cool thing about this is that it acts as an I squared C peripheral. So the Pico drives the cellular module. I got it working except for like a very small change. And I have my Stemma connector so that I could connect any sense that I want. And, you know, collect data. I need to further refine this design. But I was really surprised that, you know, even though I saw like, you know, that I got it working in one go. But yeah. Here we are, Pico phone. Congratulations. That sounds like super fun. All right. Well, you know, if you end up using circuit pi phone with the Pico, we have a couple of cellular modules, libraries for like the AT command set. If you're using AT commands, you might be able to just get it working. That'd be fun. You could just like plug in sensors and use all of our libraries to get sensor data over MQTT or RAS. Yeah, can you say different? Yeah. I did use circuit pi then, you know, it was quite easy to, you know, download the binary and get going. Okay, cool. All right. Keep coming back and showing that. And if it gets to a spot where you want to share it, you can email me ptadafrid and we'll put it up on the blog and in the newsletter. Yeah. I think this is the first Pico phone so far, I've seen. Pico phone. That's what I'm calling it. Pico phone. I like it. I never thought of a name for the project. Thank you. Now you have a Pico phone. Well, everyone, you know, you saw that rotary phone that used our stuff. It was the portable rotary phone. So some of it, like, there's a lot of cool phone stuff that you can do. And now we have another chip. All right, cool. Thank you. All right, thank you, Si. All right, next up. Ron, we're going to speed round it, everybody, because we have eight minutes. So take it away. If everyone keeps it like a minute-ish, we can get there, Ron. So I've been slowly working on putting more sensors around my house. And so I started working with an ESP8266 and a BME280 to read temperature and humidity data to send it off to a server, a Node.js server I've running. And I have a few of them around just because I live in a really old drafty apartment. So temperature's different everywhere. But I wanted at least one of them to have some display. So I picked up the unique display. And so this will deep sleep after, for a minute after it sends data off to the server, throwing off a 6,600 milliamp hour battery. And then it updates this about every three minutes, three cycles, because you can't update these too often. But yeah, it just, it's using these ADS1115 to read the battery voltage and also send that off to the server. That's cool. All right, you've got your little like low power sensor module. Good work there. Yeah, thanks. Nice work. All right, next up, let's go to... Two, two, three, one puppy. Hi, so I have a project that I've been working on for a pretty long time. It's called the Carbot. So you can kind of guess what it is, but it's actually, in my opinion, no need, no, I don't mean to brag, but kind of cool. I mean, that's cool. Shut up. I'm gonna share a tab. There's also a video, I hope that's okay. Yeah. We'll see. Yeah, as long as you can show it in like a minute or so. Yeah, so I don't have the actual thing, it's in the garage under my workbench, but... Yeah, it's a car. It's a carbot, yeah. It's a carbot, carbot, carbot car. Goes in the garage. Oh. And that is cool. That is cool. Cool controller, carbot forwards three. This is live from the Amazon warehouse. The powerful controller, carbot forwards 15. You've become the Lego Turtle. Fuck off. Fuck off. So, whoops, don't want to play it again. I've got a few pictures. Yeah, I just... This is me working on it. That right there, can you see my mouse? Yeah, yeah. That's a power bank to power it all inside of it. I'm gonna click through kind of fast. It's got a lot of wiring, speakers. My first Tesla. This came... This was like a kid's car from Amazon, so it was a cheap radio system. And then all the inside again and me working on it. So yeah, that's it. Wow, it's so awesome. Good stuff. If you write it up as a project, let us know and we'll put it up on the blog and more. I'm sure this will go viral, as they say, because it's an electric car and it's Alexa. It's all the things combined into one. I love it. Good work. Let us know. If you post it online, we can... Okay, the only thing it needs next week when you come by, I want you to add some more LEDs. I think you have to add some green here. The ground effects. I actually bought two side light Neopixel bars that I was going to put on it. Yeah, yeah. You gotta do that, because you gotta be safe at night. Okay, I was going to put them in a sword, but okay. All right, we'll see you next week with some more LEDs. Okay, don't epoch them. Just use tape or something to take them off. All right, thank you. Bye-bye. Next, Joey, how's it going, Joey? Howdy, y'all. I'm bringing back a project that I kind of showed a few weeks ago, the PyCorder. Yeah. I did another revision of it that's kind of a little bit different, fixes some of my mistakes and adds some buttons instead of the touch matrix. I'm going to share my screen really quick. Yeah. So this is a demo that I did a while back with the Elwin book, but this is y'all's air quality monitor. And so, yeah, it's just using this to kind of page through different screens of statistics, kind of air quality over time. Yeah, it's just, and then you got this little 3D printed case that I'm kind of iterating on. But yeah, just like a second revision of the PyCorder to kind of, yeah, begin this thing where I could share it. And I put the design files up on GitHub so I can share that in the Discord chat whenever. Yeah, thanks, Joe. Yeah. All right. All right, most impressive thing for me is you managed to keep that short memory display from ripping off of the connector tab. Be careful. I'm a very delicate. Preacherous. All right, thank you, Joey. Keep on making cool stuff. Watch as I end this one. One, two, three, we still have four people. So if everyone can keep it to under a minute, yeah, there's more people. All right, Ariel. Ariel Wolff. Hey, A1. Hi, hi. Ariel, I'll put my camera up. So I'm on a team where we have a car in university and we make a car. I'm on the data acquisition team. So we have, this is like a tie rod, I think it is. And I use little strain gauge and a Pico and amplifier. And if you look, the LEDs light up depending on what direction you pull it. So it's very light bends, but with the amplifier board, the data actually comes out, which was very difficult to do even though it seems very simple because amplifiers were very difficult to use. But yeah, that's it. Okay, good work on that strain gauge. Looks like you've got data coming out and you're ready to log it and keep your car nice and safe. Every person that works on a car does a little bit together. I hope you win. Yeah, thank you. Congratulations. All right, good stuff. Thanks. All right, next up we're gonna go to Dandy, then Mark, then David, if we can get to everybody. Hey, Dandy. Hey, how's it going? Hello. So when I was last year, a few months ago, I had just designed my first PCB and since then I've designed a whole bunch of them. I kind of got the bug. So I'll show a couple. My most polished one is this thing, which I just put on my brand new Tindy store. And this is called the Ohm Parade. And it's a little variable resistor or programmable resistor. I was thinking you could also think of it as a digital potentiometer, except the digits in this case are your finger digits. So you flip the switches and basically you can turn this into any resistance between 10 ohms and two and a half kilo ohms and then plugs right into your breadboard and kind of use it when you think kind of like. You're prepared for any situation. Exactly, any resistor you need, or you can plug in a little LED and see how the brightness varies with different resistance. So just a little handy tool to have around and get my feet wet in designing something a little more like a polished product. Good luck. And then lately I've been way into PCB art and this is what I'm really excited about is this badge I'm working on. That's the perseverance rover. So soon I'll be doing a batch of these in gold too. So this is kind of a tracing of the details of the perseverance rover mast. Yeah, good use of the mast to make it look like the horizon on Mars as well. Yeah, it looks like Mars. It looks like it's smoking. On Mars, yeah, you get the copper showing through. Yeah, that's a really nice effect. It's cool. Thank you. All right, thank you Dan. You come by. You have a cool art. All right. All right, now we're gonna go to Mark and then David, let's see if we can. Grab up in a minute. Yeah, try to do the best again. All right, this is just quick. I was doing my numbers last week and just before the show, of course it is going dark. Moment. There we go. Yeah, that's cool. Yeah, I just managed to get it all soldered up and try to make sure it works before I actually epoxy down the covers on top of it. And yeah, the next step is to actually hook it up to the, hopefully the Feather S2 so it can control it through wifi. Yeah. And this project is for folks to be able to find which house is yours because some of them look the same and now you're gonna have the only multi-color house numbers. Yeah, being able to make it flash when people are coming by and- That'll be funny. They're like, find the one in the fucking light. Yeah. All right, good work Mark, very handy. Thanks a lot. All right, next. Thank you too. All right, David, place out. Hello. So this is a pre-stemmer kind of eye to see board and this is a stemmer board. And then I figured out that I could do this and then I can plug one of my old boards into this and I'm gonna- Yeah, I know. So yeah, that was my great idea to soldering. It's a good idea. And then, okay, I think time out because now you have another show to run. Yeah, we gotta do another show. Do you want- This is a great idea. Good idea. Good ideas. Do you want to come back next week and share more of the collection? Yeah, sure, but this week is special because I don't have to go to sleep too late to be in sync with you because we are not in the same time. Oh, there's no fun at all. All right, well, it's good to see you. Good to see you. Okay, we'll keep coming back and thanks for sharing that. All right, thanks everybody. Well, we had epic, like 15 people. That was one of the biggest show and tells we've done in a long time. Okay, well, people come back. That's good. See you again. Nature's healing. Okay, so we'll see everybody next week. Next week, JP, I believe is host and then Noam Pedro and then we're back after that. We're rotating all these out so everyone get a chance to host on our team more and we'll be doing Ask an Engineer at 8 p.m. just a couple of minutes and thank you so much everyone for making us the best half an hour of our week, every single week, show and tell. See you in a few minutes. Don't remember, I'm cool. Yeah, you gotta get a TikTok though. TikTok sir doesn't count. Oh no.
