 Hey, what's this? It's show-and-tell. Yes, it is time. We are ready and First of all, I want to say hey to everyone over in the discord chat and if you are wondering how to come on to this show and tell Where you show stuff and talk about it and maybe I ask questions or people in the chat ask questions You can find out all about that either by going to the Adafruit website to the blog section or head on over to our Discord which is at adafruit.it slash discord and that If you scroll up a little bit We'll show you a little link where you can come on into our stream yard And if it seems like it's full if it's telling you you can't come on and we still have time People will drop out after they go and I will bring on new guests. So We've got about 29 minutes left. Let's get through this and then there's going to be an ask an engineer right afterwards And I don't want to go long so a couple minutes per project and and we'll get going so first off I'm going to bring on our good friend Odd J. Hey J. How's it going today? Good. Good. I just want to show off. I Master the yassi bots, which I put on my head, but yeah, you guys are done and they're ready and they're moving and grooving Oh, those are cool. I'm gonna go. I'm gonna have you go full screens Oh, yeah, so I made more of them and I actually made sure it's like write everything down and document them very well for other people Can make them so I'm going to be hopefully soon releasing these guys on a fun Thing with digikey zoom so look out for that That is excellent. And uh, those are tell me what's the primary? Guts of it. What do you have thinking and being a brain in there as well as driving motors? It's mostly a three-pronged project, but there's just a single servo and a different drink it So it's super lightweight, right? Okay, 19.2 ounces of leave. Uh-huh. I would like the other day But yeah super light where on your head So sit there and just chill out and be a fun Halloween thing or just for kissing people like I do That's fun. And you've been refining this design and other like shoulder bot friend Companions for a few years now. How many revisions do you think major revisions of this are we into for the one you're going to release? This one is technically Aussie v 11 So over the past three years of a 11 different version of the spider not encounter not including the paradox versions which technically mean about 17 different versions. Oh, well, that's terrific. Really cool. Well Thanks for showing to us and and let us know when those are out as as a guide I post on Twitter on my social media is that way people can like find it and make their own versions. They'll be awesome Yeah, yeah, we'll definitely share that once you get that link up. Thanks. Jay. Good to see you. Yeah. All right Next up we've got no a Hey, how's it? Hey, what's the folks? Yeah, so this week we got our little IS 31 FL 37 41 LED matrix And this is a collab project with Liz Clark and Phil B So I made a little case for the thing So this is kind of what it looks like outside of the case You got this little PCB bracket and this kind of makes so you can kind of put any feather So this is the feather RP 2040 But in this project, we're using the feather sense an RF 5240 because it has the PDM microphone built in And it's a snap fit kind of thing you can attach it to two other things to if you just want to print the bracket And I also have this little button pusher for hitting the reset and real quickly. I want to switch the demo code so this is From Liz she ported this from the water spectrum analyzer from the micro lab library from Jeff And then this one is Phil B's. It's still in development, but here it is kind of Pre-release So it's got like a different effect to it and it's got like more rainbows But yeah, this is a really fun one So folks want to build an audio reactive LED matrix Cute sized you can do that with the feather sense. Love it. Yeah And that one is a frequency analysis, so it'll do like high pitch low pitch middle like a FFT kind of range of what it's hearing. It's not just like a Loud or not loud, right? Yeah, I think so Yeah, you'll have to check the learn guide and all right Yeah, what's the whistle at it and beatbox at it and see what happens. Yes I will I'm actually been having this with my pico mini fighters. I've been having that kind of like Yeah, I saw I saw you drumming Yes, finger drumming and I saw that was it was next to it as your finger drumming companion. Very cool Yeah, it's very fun. So love it. We got the learn guide out there. So awesome. Thanks for sharing that. Take care. Thanks. You too All right, so let's see next up is he was just name-checked. It's everybody's favorite dragon paint your dragon. Oh my goodness. Hi All right live demos Yeah Everyone's You know the more just Design these shutter shade LED glasses and the driver board has Bluetooth on it. So I've been Trying to use the Bluetooth connect app so that I can send messages You know scrolly messages. Yep, and I changed the color on the glasses and it was working here You change color like it worked perfectly right until the moment. You said hey you're live. So I Can't change the color. Yeah, but yeah Something's gone wacky with the message But anyway, that's a work in progress But at some point we'll have a guide and a few projects to go with Yeah, that's looking looking good and I just got a set of those and put them on and it really works so well to have those You did some experimentation right with different Cutout shapes and didn't you and having like just these horizontal lines seems to be the easiest to look through and still have A lot of surface. Yeah, we originally we thought like a spider web motif would be cool But having all those lines crossing your vision. Yeah, it was really problematic But just the you know the whatever 90s style shutter shades. Yeah, it worked really well. So that's what yeah Yeah, you always hear things about how like our range of Vision is sort of almost nearly the same as a 16 by 9 letterbox like our peripherals way wide compared to his Vertically, so it probably makes some sense that having nice wide slits in this Makes us feel less like falling over and throwing up then. Yeah, and if you look look Through, you know an entire slit. Yeah, we're down and it yeah kind of works. I love it. It says dragon now I know now. Yeah Moment, it's it's working, but yeah, you're really cool Love it. Thanks for bringing those on and I can't wait to play with that Alright, let's see who else if we got here ready to go. I think it is everyone's favorite Scott who's raising his hand tan Newt Hi, I saw your little your little Scott down there in the thumbnail you went. I know I I thumbed up I was like, all right. I'm ready to go so I have been Diving deep into the Raspberry Pi as folks who watched my deep dive have seen But I got an Osh Park board back that I that I made and it's a Unofficial pie hat or whatever the unofficial ones are called But basically it's wiring it up so that it's easy to debug either with a JTAG or an SWD Plug, so that's really awesome And then I just have spot for four LEDs here at the bottom and the signals are broken out as well So if you just need to like see if an LED blinks and what the signal is doing You can monitor that as a way to debug Then at the top we have this you are output here So it's it's the same pinout as like a USB to you are converter So you can just plug the converter straight in and then I have a semi QT port up there as well on the ice-cream sea lines So I'll show you what it looks like so I just put it together and it does I didn't quite test everything but here's my CM4 IO board and then I can show you that my beautiful soldering There with the different color LEDs and the resistors for that When I was talking with the more she's like, you know Make sure that you can hand solder it because we won't assemble it But we could sell it as a bareboard potentially. Oh nice If folks want this I'm happy to share the Osh Park link as well And point you to what we're to get all the parts It's really pretty straightforward and I Wouldn't I soldered The this is like the stacking header for the pie, which is cool in theory, but like getting this inner row I had already soldered this j-tag. Oh, yeah, you know that thing too. I did you probably can't see it I definitely like bumped it a little bit. I think I would do it in the reverse order time But you know generally pretty good And it does work at least the SWD works because I'm using that New York works and LEDs work Oh, that's great. That's really helpful for your for your debugging and that just goes into it normal. What is it 40 pin? Right, right, right there. Yeah, so this is just like if I take this off It's it's just where on the IO board they have like the the pins the 40 pin header And it should I think the pin out is Uniform across all the pies So I think in theory it should work for all of the different pies that have that 40-minute header Which would be cool Nicely done. Very cool. Yeah, so if folks want to know more check out my deep dive on Friday We're gonna be talking more about Raspberry Pi stuff So that'll be super cool and maybe maybe we'll get USB working. I don't know good. That'd be wild Ah Good excellent. Good luck cool board. Thanks for bringing that by and we'll see you next time. Thanks. We'll see you Friday. Yeah All right, let's see who have we got coming up next. It is our Our favorite Liz blitz city DIY. You're our favorite Liz Okay, thank you. Are you our only Liz? I don't know. I Am like one of three lives is at work. So it's okay. Okay. Yeah, you're singled out for a different community You know the Liz cool. Uh, so I've been doing kind of a Disconnected IOT project where I've got Feather Rp 2040 and SCD 40 CO2 sensor because I want to monitor some CO2 levels about having to necessarily connect to the internet Also speaking of work So I made so that it's logging the data to the feather So I'm gonna share my screen. So then it logs to a text file and then you can chart out that data Like on Google sheets really easily and get that visualization so I'm hoping to make this into like a Kind of self-contained box So I can like leave it places and check it over time. Oh, that's great And do you log on to an SD card on the on the microcontroller or just to some e-prom that's built on? So this was just the internal file system of certain Python. Yeah, all right, right. Yeah But you too could totally do that too. Uh-huh. Oh, that's really cool And so you're gonna be able to just take this leave it somewhere collect data and move it around so that you have Sort of a much simpler system than wireless and the internet and all of the things that can be a challenge with that I'm guessing. Oh, that's great. Yeah And you said you're gonna be just deploying this at work to do some testing there Yeah, just some COVID things have been lowered and I'm curious on what the data actually looks like Yeah, oh, that's great very cool, and is that a project you might be writing up and sharing at some point once it's Once you've tested it out in the wild Possibly possibly. I'll definitely show the code no matter what. Yeah, terrific. Good. Excellent. Well, thank you so much for bringing that on Very nicely done. Talk to you soon Alright next up we have Darian who is coming on for his first time and giving me double thumbs up. Yes double thumbs up. Can you hear me? Okay? I do you you sound great fantastic very nervous, but very happy to be here very excited. So I've been working on the thing I I love the mag tag, but I don't love so much I don't like the refresh of the yank and I wanted something with a with an RTC attached so I ended up taking that making some modifications and Started just a you know a metro kind of prototyping within ultimately designed like my own like circuit board like But with a sharp memory and pixel display and with oh, I just I moved it. I'm over back here. Sorry about that. Yeah. Yeah Yeah, oh, I love that display. Yeah. Yeah. Yeah, I love I love it. I love it, right? So So yeah, it's still with an ESP 32 s2 So it should run Arduino and run circuit circuit Python. I just need to write a library for the RTC But but it's I'm excited about it. I've got some demo code. It's actually launched on on on crowd supply So they accepted it excellent. So that's kind of cool So so hopefully I will finish the the demos and and and ships and prototypes off and it'll launch soon Super can you share a URL yet or a certain term people can look for? Yeah Yeah, I'll post it in the in the disc over in our discord. That would be great And the board files already posted in GitHub. I'll point to those as well That looks great. I'm gonna see if I can make you that particular screen bigger. Let's see. Let's solo that There we go now. It's huge. Okay. I've got a little bit of demo code where it will like give me set my alarm or a timer Or give me my weather Maybe If I can push the button correctly And are these a little capacitive touch buttons or past the touch but yes, and in full transparency I I only did a capacitive touch because I was not confident in being able to solder on both sides of the board so the So, yeah, so the demo code works pretty pretty great it connects to the internet pulls these things down I'm I've got some examples. I'm working on with some integration to home to home assistant some integration Alexa so we'll see I love it. It's a really clean design. I'm guessing you'll end up with some other look to it Maybe at some point that's even that minimalist thing cuz I love the minimalist black. I like I like it Well, I like minimalist, but it's open source. Yeah. Yeah, who do what they want to do what they want. Yeah Beautifully done. Good. Well, I'm really looking forward to to seeing more and checking out the link when you post that Thank you so much Darien. This is really nice nicely done. Yeah, all right You bet That was way cool, I dig that a lot. All right, let's see who we got up next we have Todd bot right here is giving a thumbs up. So let's bring on Hey, Todd, how's it going? Hey, hey pretty good. So I've been working with Circa Python and in that MQTT lately and so I wanted to show this little silly sketch that hopefully will focus and This kind of shows how fast it is to get up so that was basically getting up onto the Wi-Fi and connecting and then there's three little bouncing John Park heads and when they hit the edge, they emit an MQTT message, which I can show you Let's see here or not is this up working So here every time Over exposed Focus here we go. You can kind of see it. Ah, dang it. Well, anyway so yeah, so this is showing that that that it is actually emitting the MQTT messages and The cool thing about this is that the it's actually doing animation with display IO as well as polling with Doing the MQTT poll which normally you can't do because it kind of blocks everything else But you can you can pass in a timeout value to let it continue on and that seems to be working. So that's basically it That's really that's really impressive So in sending out the MQTT message, you can have another device kind of pick up the ball and Carry on with whatever that triggers have it make a sound effect or light up a light or wherever Exactly. Yeah. Yeah in this case It's going to be triggering some servos and some lights and stuff when it hits the various things. I want to get done on the fun I'll send you the URL. It's hard to do in in reverse on the camera We'll stick with yours. That is really cool. And what is that groovy little board you have there that you're showing that on? Yeah, this is so this is a circuit Python capable board called the Lily go TT go ESP 32 s2. I think oh and And yeah, it's pretty great ESP 32 on the back with eight megs of RAM. It's got an actually it's got actually also got an SD card slot there So you can plug in and like you know save a bunch of data to SD card That's one of the things I was using this for before was playing images off of it sort of like a little a little mini Like photo frame sort of thing. That's really cool. Yeah Whoops, what did we do? There you are. Sorry. You inked you right out of there. I Yeeted you as the kids say, uh, I don't really know what that means But Michael is laughing. So maybe I said it right So is this a project that is being developed as something you're gonna be able to show share in the future Is it up on your github if you want to learn more? Yeah, like all this stuff will probably up on my github in about a week or so, right? Yeah, good. All right. We'll have you back on to show us more more servos and things very cool. Thanks, Todd All right, Michael's giving me the Micah. Sorry Micah is giving me the thumbs up. So he's ready to go. Hello Let me unmute you here Sorry about that Um, I think I've got something a little interesting So you know those seven-inch official Raspberry Pi touch screens. I do Well, they're not HDMI and if they were I'd have it attached to my laptop right now but instead their DSI and I'm not a huge fan of that so I Did a little something and it's very hacky and it's very strange and I love it. Oh So how? I Am gonna share my screen just to show you how this works. All right one second The anticipation is building. I've got OBS studio running on my computer and These are my and As you can see I've also got this eye or not not that I've got this icon which is called fluffy display It's an out wait. Is it glitched on your screen? I Am seeing just a still image of OBS Darn it. I'm gonna stop and restart my share. Okay. I see your cursor now All right, bring that back about that. No, no worries. This is how it goes All right, here it comes. Okay. Oh, no your cursor Yeah, you know, it's not wanting to show some layer of some of it. It looks like all right We have one more idea and then and then I'll just explain it. All right Can you point the camera at your screen, that's always the analog loophole. Yeah, I do have as you have a webcam But essentially this is just OBS studio. It's just it's an application designed for streamers to Livestream to the internet. I'm kind of hacking it. I'm using it to capture a virtual display I've got this outdated un Unmaintained application from like 2019 called fluffy display You can't see it because it's in my taskbar But it is running in the background and what it doesn't is it creates a virtual screen on my Mac That doesn't really exist But it lets me do a screen share from that virtual screen and I can also move my mouse onto that virtual screen So in OBS, it is capturing that virtual screen. So if I move my mouse down You can see it vanished, but now it's in the virtual display and it doesn't actually exist That's mind-blowing So here's the cool part. I Figured out how to cast that to a Raspberry Pi So if I just grab my keyboard My Raspberry Pi is running on a separate keyboard, which is a little annoying because I didn't have time to set up barrier or whatever But if I run VLC VLC media player And I start I start streaming from here Doesn't appear to do anything, but if I start VLC And I see it on my end, but it's happening. I'm gonna switch my camera so you can see it So if I go to stop screen share I'm gonna change my camera So this is that virtual desktop and if I move my mouse down You can actually see it. There's a little bit of lag But I see you drawn about wirelessly connected to my computer over Wi-Fi So that's wild. Yeah, that took a while and I think I'm actually gonna use this it is laggy But it took it took a little bit of tinkering and I think it's pretty cool That's pretty cool. You've come up with yet a different way to to share the the display with your device. I Originally had it working on an 804 1.4 inch to 240 by 240 pixel tft But it was a little cramped as you might imagine Well, that's really cool. Can you bring that by next time we want to see it? Which one the the tiniest screen you've got yeah do it That was a little one. Yeah next next time you come by all right We're gonna I'm gonna go because we're gonna bring the next person, but very And thank you for sharing that take care Alright next up we have Michael. Are you ready Michael cuz here we go. Hello. Hi. How are you? I'm well. Thanks. Yeah, this past week I actually made this cool accessory that has a blackberry keyboard on it and if you can plug a clue into it So basically adds a keyboard on The clue which is pretty awesome here. Let me switch over to Here we go So then yeah, you can see I can like I love it on it Yeah, just a cool little thing. I have the magnets on it that I featured last week So yeah, just a cool thing. I got like super Interested into the keyboard With my satellite phone project it's still work in progress, but Yeah, so it's using this cool thing and it's all connected with the airfruit dragon tail connector. Oh, right Yeah, oh That's really cool. So so you're did you say this is a blackberry? Keyboard or something an existing Yeah, it's actually a real blackberry keyboard It's using the I think it's the TT go driver board That's just connecting through I to see Which is pretty convenient. So yeah That's really nice. So that's a little board that translates whatever tiny ribbon cable comes off the package of the little keyboard and then gives you some I squared C to Talk, yeah, and it's compatible with the Both Arduino and circuit Python library That is made for the big there's another company solder party that makes a very similar driver board for the Blackberry Q10 and you can use the same library with it too. So that's really cool It's such a what a you did a great job with the design of love that you're able to use the edge connector to just plunk Board elegantly into this little Apple to look in keyboard box thing Yeah, I love designing stuff. So yeah, it's fun really nicely done. And can you tell us a little bit about your design process? Are you? iterating in like Cardboard and then going into 3d and doing printing like what's what's it that process like for you? Yeah, so I use a tinker cat Because it's it's super easy and like I could be using something like blender or autodesk But like you can get like 90% of the way there and like half the time with tinker card And I just like face basically have like two Things side-by-side and then like I can fit them together when I print it Yeah, I am making a video right now on how to make this so anyone will be able to oh great make this and Yeah, so When you do that, yeah, yeah, I'll post on the discord once it's once it's up Great really nicely done and thanks for sharing that. We'll see you next time All right and to play us out. We have mark. Hey mark. Hey so a couple weeks ago I was on showing just some schematics and a diagram of a board I was working on my first microcontroller board and It all arrived and I can't show it on my close-up camera because I literally finished soldering this a minute before I showed Up into the stream chat to start So it won't be super clear on my webcam, especially with the reflections But yeah, the first ever microcontroller board I made that this is aimed to have Wi-Fi and to be able to be placed somewhere in your house to hook up a sensor there is a Stem a Qt port on it, which I hope works And it has it was basically to take something like the fun house to the mag tag and remove the screen and add a couple visual elements to leds in a neopixel and couple user buttons so You could hook up a temperature sensor a co2 sensor whatever you want hook it up to Adafruit IO and And Just have it work without a lot of other components to try to make it. Yeah, that's great So it's kind of a minimum viable Adafruit IO Sensor connector That's what I was aiming for and just for the practice of building a board I actually got a chance to plug it in and it showed up as a comport Congrats, it's exciting. Yeah, I'm actually hoping I can load software on it now and maybe yeah the components on it work That would be a good start and hopefully shrink it down for the future Excellent, and do you start with? Will you start with like the fun house? Image as your starting point on the code for For flashing it that sort of is looking at I I learned a lot from the fun house schematic and the mag tag one the fun house is probably closest to this board so start there and Next school still hopefully get circuit Python running on it and see how it actually works That's excellent. Really cool. I love the idea So yeah, bring that by when when you get your next step in the process will be excited to see it Yeah, thanks as said it was just lucked in that the parts arrived yesterday And I spent all the time after work today quickly assembling it. That's great Congratulations on getting it up and running that quick. Thanks a lot. All right. Take care. Thanks All right, well, that's gonna do it and our time is up. So stay tuned for ask an engineer, which is happening next Goodbye everyone. That was your show and tell
