There's more. I don't know if you can check those out at adafruitdaily.com. Let me catch my breath. All right, are we ready to start the... Yeah, let's go ahead and start this week's project. This next project is a bit of a work in progress, but we have most of it ready for folks to check out. This is a 32x32 RGB display, and it's being powered by the Feather RP2040. This is that new chip from the Raspberry Pi Foundation. To make this work so that it's a bit of a plug-and-play situation, we have an RGB matrix feather wing. This guy here has all the ports and connectors for plugging directly into the style of displays, which tend to have a 75 hub connector, which is this thing over here. What we've done is we redesigned the frame and the grid diffuser for the display, because it does come with a stock frame and a stock grid, but it's super easy to take that apart and make this. What makes this possible is this awesome material called black LED acrylic. I just took it apart. Super easy to take apart. This is the frame that's 3D printed, and there are these little feet here that are attached with these screws and hex nuts on the inside. It's kind of a good way to get a really nice secured fit. If you don't want to use heat set inserts, you could always create like a polygon shape and press fit hex nuts in there that way they don't pop out. So that's what I did for this one. Grid, two feet. I mean not a grid, a cover, and these two feet there. Great. So let's talk about the acrylic. This is black LED acrylic. We stock this stuff in the Adafruit shop. It's opaque, not super transparent, but it is designed to really make LEDs and lights pop. So let's look at the display. Here's a display with the 3D printed grid. And when you put this over, you can see here how nice it looks. Thing about the diffusion is as you get further away from your light source, your light source, you kind of get a little bit more blur. So the further you away, the more kind of evenly diffusion you get. Now you're just looking at kind of like a disco party here. But pretty cool optics here. Yeah. So why don't we take a look? Oh yeah. So let me keep kind of taking this part. So that's the black LED acrylic. We stock this stuff. We love this stuff so much. And you can cut this using a scoring tool. And we have a video on our YouTube channel that shows a little bit of the process of cutting this with the scoring tool and a paper template. So that's the black LED acrylic. Let's talk about the grid. So this grid is 3D printed. And it kind of just press fits into this frame here that has the doubler feathering secured to these little standoffs there. So let me take the grid out. It just kind of rests over the LEDs. So I'm going to kind of take this off here like that. So this is all 3D printed. And this is the bare PCB, right? Cool. Nice and thin over 1,000 LEDs here. Wonderful. So here's the grid. You're going to need a 3D printer with a bed that's at least 200 by 200 millimeters. Actually, I think like 210 by 210. Yeah. So this print's here. It's just all perimeters. There's no infill. It's all perimeters. And it's like that thick. So like, I don't know, 10 or 5 millimeters thick. Yeah. So here's the grid, right? This grid is what really makes this effect work. Because when you lay it on top of the PCB, it's actually like encapsulating the LEDs so that none of the lights are leaking into each other. So that's kind of how this effect is working. So let's take a look at what this looks like with no grid and some black LED over it. So similar effect, but because the LEDs themselves are, the diodes are inside of a circular sort of lens, you get these circles, right? You get these dots, which is still a very cool effect. You want to go with like this light bright type effect. So you don't need the grid, but the grid is what makes it a square, right? Yeah. Wonderful. All right. So I got another display and I'd like to kind of show that display and its stock stuff here. So here's the same display. And this is the grid that comes with its stock. And not much really to this grid. The reason why it doesn't quite work is because it kind of gets flush with the LEDs. So you can't quite, I haven't turned this on, but we'll see if I can just do this then. Since this is already on, let's go ahead and kind of put this diffuser back on, the kind of stock one, just to show what it looks like. You know, it just kind of makes it a little bit more diffused, I suppose. Like the circles look a little bit more bigger, maybe. But yeah, you can see here, it's kind of hard to get that effect with this thing. So that's why I chose to take it apart, which is super easy to do. It's got a couple of screws that you'll need to take out, but relatively easy to do. There's no glue or anything that holds the PCB to the stock grid or the stock frame. So that's cool. And it's easy to take part. Maybe just hang on to those screws and you take them off. Yeah, so let's see. So that's this piece. I do want to show that this is running, so this is using circuit python, right? And the library to get these matrices working is called the Matrix Portal Library. The Matrix Portal Library has support for different hardware, namely the M0 and the M4, but also, coming soon, the NRI-52840 and the RP-2040. I got a PR that's sort of a work in progress, so that's why our Learn Guide is still a work in progress, but that is under development and hopefully we can get that out within this week. But having said that, let's go ahead and plug in another board. Again, this is the RP-2040, that Raspberry Pi chip, but I also have it set up a little bit differently over here. There goes the mouse. So this is mostly the same hardware, but a little bit of a different configuration. So the RGB Matrix Feathering can be set up with male header pins or female header pins. In this case, it's using the female header pins. Let's see if I can brighten this up a bit. Yeah, Peter's doing that too. Thank you. Yeah, so these have female headers here, and in this sort of configuration, the IDC header is on the bottom of the PCB, and that allows you to connect it directly into that HUB75 port. So if you want to make it this way, here's one note too. See that little notch there on the silkscreen? You want to make sure that that's lined up with the notch here, because otherwise it's not really keyed. So you want to make sure that it gets in there. But anyway, that's this sort of configuration. That's the RGB Matrix Feathering, and this is a Feather M4. I can't get it to focus, but believe me, that is a Feather M4, and it's because it has female headers right on there. You can just plug this in on the top there. So no need for an IDC cable like I have here, but this is pretty much the same kind of hardware, right? And then to power it, I'll just kind of take out this. So how are you powering this? I have a beefy 5 volt 10 amp power supply. That way, if I want to light up all 1000 pixels white, you can do that. And so that's this power supply. And then this little thing is just a little switch that gets added to the barrel jack there. It's for ease of use. So I'm going to plug this in through micro USB. So it starts powering on, and then I'll give it that extra power because it will need it. So it's running the same library. So it's cool that the library has some handlers there for detecting the hardware, whether it's a M0, M4, or RP2040. So it's running the same library in the same code, a slightly different hardware, right? Yeah. So go comment from Bruce saying that he really likes the LED projects. They're visually engaging for the whole family, which they sure are. And we'll jump into a learn guide from John Park that really walks through this code, the library, and creating these spreadsheet animations. Yeah. I'm just trying to figure out what's another kind of thing here. You notice here, this power cable here, this power cable, like, comes with all of these displays. But I've kind of tweaked it slightly. It's slightly more simplified, right? I'll show you the original one because I have it over there. But the RGB Matrix feather wing has these screw block terminals, and that's what these little prongs connect into. You just kind of screw that in there. And then this just clicks into this piece here, which has the just power and ground, right? So that's how the power and ground is connecting to the feather wing. And then here is what the kind of default cable looks like. It has a double-headed, kind of double-headed snake here. So all I've done is I just cut these wires here, and then just splice it into just one of these connectors. This is nice if you want to have two connect, you know, if you want to connect two, if you want to power and connect two displays, you can daisy chain them together with this cable. And it comes with the display. Another cable that the displays come with is this IDC cable, which is what I'm using for this particular setup here. Because I like using the doubler feather wing because I feel like it's more mechanically stable when I'm plugging things into the display in the back there. So that's why I kind of have it set up here in the doubler. But if you'd like, you can set it up this way too. So you have to make that decision on your own. But the frame should fit this thing too. I'm just gonna, it's just that it's, you know, screwed to it. That's why I have this kind of fixed there. Real quick, while we're still kind of on the subject of the cabling, had a question by SquidJpeg asking where you got the barrel connector with the power switch. I linked that in the all the chats. Yeah, it's a real quick, really good way to turn these on and off without having to stress the power, the jack there, the barrel jack by plugging it in and out. Yeah. And we have these in a couple of different configurations. You also have a USB one as well. Oh, look at that one. For USB. It's a little bit different. Nice little chunky on and off rocker switch. Oh, actually this one's smaller. It is, yes. It's like finger. But super chunky and I don't know, it definitely should work with all the different power supplies out there. So yeah, very, very nice switch. I really like this as well. Sweet. So let's put this back together, shall we? So how do we do it? First, I would, you know, secure the PCB, the doubler to this thing with the headers, plug all the stuff in. So this goes in like this into the frame first. The grid fits over here. I like to have the surface that was printed on, the print bed surface facing out. I just feel like that gives it a better look. And then this just clicks into the frame. You see how it's flush. And then the frame has this kind of a ledge here. So it prevents the PCB from going all the way down in. So that's a little design thing there. So that's this piece. Let's set this aside and work on the cover. So as you have the cover, whether you want these feet or not, I like them because it's less likely to tip over. You want to grab your black lead acrylic, matte side out, shiny side facing up like that. That just clicks in. Reflections. And then you want to be careful inserting your grid and your cover into your grid, your frame. They all just slide in. There's no screws to keep that together because it's so thick. It just kind of stays like that. And you can see it's this thin. Cool. All right. So there we go. Any questions? Will I power this guy on? Let's see. Just a general curiosity on why there are two power pins that go into one. I think it's so you could split the power for we're tiling with more than one grid. Yeah, which particular? This one. Oh, this one, why it has, why this one had two. Yeah, I barely briefly talked to her. But yeah, in case you want to connect two displays and through one power source, that's why the cable comes with two. It expects you to connect multiple together. So that's why it's set up this way. But I've cut it, and spliced it and simplified it and reduced the wiring. So it's a little less, you know, all over the place. Otherwise, you have to coil it and it looks like a mess. And that's why I recommend that. And then Don K has a question about the Matrix Portal board. You're using that instead of the feathering. What are the library differences that are required? It is the exact same library. That's what's amazing about this. The library has kind of detectors inside of it that says, Hey, if this is a Metro board, run these pins. If this is a NRI 52 840 board, run these, et cetera, et cetera, for all the boards. So great job. Shout out to Melissa for handling that. And Lamar, too, for like saying, Hey, let's make this matrix portal library work with all the circuit Python boards and all the circuit Python accessories. Very forward thinking. Yeah, portal base being able to support so many. Yeah, a lot of those libraries that limit Melissa works on become these like these libraries that have all these extra board supports and smarts. Yeah. So we're like pulling things out. I think generalizing it. I think what is it called the portal? Portal base. Portal base library. Very cool stuff. Yeah, so that's the answer to the question. And real quick, Jasper Henson on YouTube is asking about feather wing having level shifters or you have to drive the display using 3.3 volt signals. Yeah, that's why you want to get the RGB matrix feather wing and has all the power regulation stuff already for you. Yeah. So that's that's that's the way to do it. Very specific for running matrix displays. Yeah, that's the name. Yeah, yeah, for sure. Yeah, we needed an easier way to power this and connect it. So Lamar's solution was to create the RGB matrix feather wing. And originally before the feather, she made one for the Arduino footprints, which she has a, well, she, well, it's more of a matrix. I mean, a metro. That's what we call our Arduino Uno format. But we have an RGB matrix shield, I guess is what you would call it. Yeah, shield. You can do it little feather. Now you can do it. We'll be running into a power issue with my USB hub. Any other questions? Will I power cycle this guy on? Let's see. Richard is asking if it is possible to use multiple 32 by 32 led matrices or a 64 by 32 led matrix. I have seen if you mean if you're able to mix and match the sizes, I believe that you are able to you just have to edit what the code says for the matrix size. I have unfortunately killed our second cam by a whoops. Yeah, I have too many devices plugged in, I suppose. So I'm not sure how to fix that in Wirecast. But we'll get something going here. Let's see what we can do. Oh, it's frozen. Yeah, yeah, yeah, because I'm using the USB hub and it just drew too much power. So you all want to be careful. I wanted to load the code file. But yeah, maybe be careful. I just have a lot of things plugged into my USB hub. So maybe when you're developing your circuit Python code, I don't have you know, 100 things plugged into your to one COM port. We still have audio though, right? Yeah. Let's see if I can troubleshoot this somehow. I'm going to try to change the troubleshooting camera feed live is very difficult. I might crash the whole thing. Yeah. Errors with no text. Too many LEDs. Hello. Let's do a something really drastic here would be to just disconnect the the USB and re plug it in. See if it comes in as a as a new thing here. Hello. Yeah, you can still hear see me camera. Yay. Hello. Party parrots back for partying. Current joke. Oh, yeah. So I hope you'll like it. You know, you can check out the we have the STLs available. Also the original CAD files. So if you want to do some fun stuff there, check it out. It's on Thingiverse. I have a link in the description of all those videos. You can check out that the STLs are ready to print. Hopefully you'll like it. And then I'll let's jump into JP's learn guide. This one shows you how to set up all these sprite animations. Yeah. So you want to search for LED matrix display or pixel art and animation. This guide really walks you through how you can create the sprite sheets. And it even walks through using some software called a sprite to create to combine like a sequence of images and turn it into this vertical or horizontal strip like this where there's a guy walking and then John walks you through the techniques of like because he's an animator. He is an animator on the techniques and principles of animation. And he also has a little tutorial here on how to use a sprite, which I have to reference because like I was new to the software too, but very, very good beats Photoshop for sure to merge all this. It's almost like a script. There's probably ways to script it as well. Not as elegant as the way they're able to do it. Since it is primarily focused on building the sprite animation. Bitmap supports really nice. And this here is the the code that I'm using on this project. The only thing I modified here was I added the after when you're setting up the display here, it says matrix. It's line 19. After bit depth, I put a comma and I and I say with 32. Otherwise, this is default thinking it's a 64 by 32. So the artwork it shifts. This is on a question that Richard is asking on the YouTube about the possibility of using multiple 32 by 32 or 64 by 32 led matrices. This is where you would define. Yeah. And there's I haven't done it myself, but there's also a guide that talks about that. And I'll show you. But one thing I want to talk about. Look, download project bundle is here now. This wasn't here yesterday, right? So that's cool. So if you download this project bundle, if you click on that button, it's going to download the code plus the libraries and any dependencies. So check that out. It's a fairly new project bundler. Let me find out so I can link it to everybody to test out this grabs all of the libraries and dependencies that you'll need for every project. So you don't have to go hunting down every one of those. Yeah, that just makes it one less pretty big step. Which particular link did you want to share? The one where Lamar is previewing it and a little bit more explanation of how it's actually. Yeah, was that on her desk of lady industry? Yeah, there was a blog post as well, which I cannot find. And JP talked about it too on on his show. Brand new. Brand new. Try it out. Might be broken. Let us know, you know. But yeah, the project bundler. Okay. Okay. Yeah, another question. And then this guide here, RGB led matrices with circuit Python by Jeff Epler has an advanced section here. It says advanced multiple panels and walks through walks through Canada's colony. It's got some visuals here, some images that shows you how you can have four of these together to make a video wall. And it just walks you through all the different kind of things you need to change. So like the bit depth changes from four to two. And here's some some codes and demo code for chaining and tiling using the matrix portal. But again, you could probably use, you know, the RGB matrix feather wing or the shield or what have you. There's some extra code here. And there's some nice visual graphics. It tells you here are kind of what the coordinates are like. Yeah. And let me pop that into this discordia right there. Okay, cool. It's pretty lots of depth in the RGB matrix world, quite different from our neopixel displays. One comment from always it sounds really cool on the project they want to do with the matrix. Was it one note about like the sprite sheets? Some of these I can't share like, you know, you got copyright and artwork from folks. So I can't share these but we do have some that JP put together or maybe I'll make some if I have some time. I'd love to see it a blink of like slithering her head. If you want that, you could check out Liz's blink of jump game. See, Mike Corey is saying that he wants to build a cheaper, better UV meter for his car stereo. That's gonna be cool. You can definitely use one of the smaller matrix displays from that. Yeah. And my ongoing ventures. So I feel like I've kind of gotten every first one was this little guy, which is the eight by eight neopixel. Still one of my favorites because it's portable. It's just one feather. And it's super easy three wires and enough room on the back to add a microphone for sound. Oh, you can add all sorts of great stuff. I'd love to see the accelerometer, some sort of, you know, accelerometer based game. That'd be super dope. And it has an on off switch. You can turn it off because it is a portable little display. Yeah. Blackility acrylic as well. I mean, what else would you use? So then I went from eight by eight, you double that and you get 16 by 16. That's this guy here. And it's, you know, not too far off from the same size as the 32. But yeah, this one uses the prop maker feather wing and an M four feather so that it can power all all the pixels because these are neopixels not not the RGB LEDs that are on the RGB matrix. I am looking for a battery. I'm afraid to connect. Let's try it. Shall we? I know I said don't do this, but I can grab a battery as I do. Ah, it's still going. This one, I don't quite have bitmaps. I don't think we have bitmaps running yet on the Pixelbuff library. So this is the LED animation library for circuit Python. So a little bit different, right? Yeah. So 16 by 16, 32 by 32, eight by eight. There's the whole family. Quite different though. Yeah. Now I found my web project going on and that's so I found the, uh, learn system project bundler aka bundle fly. I am linking this as the blog post on a little bit more further in depth explanation how it's actually working. Just feel the rainbows radiating off and just and then I'm certainly saying that there's a stream sale humble bundle, which includes aspirate for 20 bucks. Oh heck. Yeah. Yeah. I get that. Oh, you can also get you can compile it yourself. All circuit Python all the time. And then lots of thanks to thank y'all for tuning in. Richard who's saying that they, uh, wait, no, was it somebody had just gotten all of the, um, the materials needed to build this and got it last night. Excellent. Let's run through those materials again. Cause I got links. So here's the feather wing. Well, Zachary, Zachary, some say, thank you so much. Here is the learn guide. Which one? No, I'm just looking at the parts. Yeah. So the feather wing, make sure you get that. Here's the 32 by 32. Again, this is very specific one. It's the six millimeter pitch version. That's what the grid is designed for. We do have a 32 by 32 in the different pitch configuration where it's tighter. Those unfortunately I didn't design this stuff for those. Um, so yeah, maybe in the future, but not now. And then here's the feather sign up. We're at a stock right now, but sign up if you want to pick this up. But if you just want to get it now, get the M four, it's a little bit more expensive, but it's still a great one. You can do the M four feather. I recommend the M four over the M zero just cause you're going to be able to to do more. It's got more Ram, but yeah, it's kind of double the price. Isn't it? Yeah. But, uh, hey, that's the, you know, the cost of the chips and stuff. I'm sure more of the RP 24 years will show up soon. I hope so. Yeah. Cause we had to use them on what the itsy-bitsy board or something. Okay. So those, listen, don't forget we have black led acrylic in stock. A 12 by 12 sheet is, um, plenty for this project. You'll have some extra excess so you can use those pieces for a smaller display or a different project. Um, it comes shipped nice and, um, protected, not scratched and all this. And, uh, yeah, we can mill it. You can cut it on your bandsaw or you can score it like we have. And we're getting a nice collection of projects now that use this stuff. Freaking awesome acrylic. I love the stuff. And then, uh, yeah, the files are there on a Thingiverse. I also have the 16 by 16 on Thingiverse because we didn't quite do a learn guide on this one. The eight by eight is indeed a learn guide, but the six by 16 didn't get to be a learn guide. So you'll have to make do with just some photos here of like the assembly. But, uh, yeah. Yeah. So there's that one. Cool. I think we are through with this one. We'll check back in, check back in next week where we'll have our learn guide for this release, but you can get the CAD files now and some of the parts are, most of the parts are in stock. Awesome. Cool. All right. That is this week's project. We're going to jump into, uh, we've got a half an hour, so we're good. Pedro has been prototyping some stuff. All right. So you already mentioned a lot of chips being used. We're spiraling using them between the QT Pi RP 2040 and the Itzy Bitsy RP 2040. And I realized that I didn't actually make any of these Lego compatible mounts for the Itzy Bitsy. So I took my, um, good jab at designing something that would hold onto them. There are no standoffs on these. So we're using these nice little clips to hold the very edge of these. So you still have access to all those pins, or if you have a header on there on the top, closer, there we are. And we'll be able to still utilize all those pins. And the way this works is that it slides in to those slots right there. Can you show me the bottom? This is my first time seeing this board. So we can, yeah. So the bottom of the Itzy Bitsy RP 2040, nice and flush. There we go. And it slides right into these little Lego compatible mounts that goes on like that. And it does not come out unless you forcefully slide it out. Have these nice walls all around. So it'll keep it in there. And of course the studs, or if you want to attach these to the back of a Lego plate, you'll have the, what are they called? Studs? No. Tubes? Tubes? Studs? I forget the name. But these should work on any Lego compatible or the off-brand Lego ones. Cool. I've got kind of a side question. This is the Itzy Bitsy. Last week's project used an Itzy Bitsy NRF 52A40. Would this fit the Tereco? Yes, it does. I didn't bring his body, but I tested it out. There are some differences between the M4 Itzy Bitsy and the M0 and the M, the RP2040 Itzy Bitsy. It's just a tiny bit wider. It's like 0.2 millimeters or something. Which is enough to not fit in some cases. Exactly. But this will fit the M4, the NRF 52A40, Itzy Bitsy and the RP2040. Just a slight modification that you would need to do if you want to use the M4. And with that, look at this, folks. This is in stock currently, $10 board. Nice. Lots of GPIO. A ton. It's basically a feather minus the lipo charging. Although you can have that on there. You could with the lipo backpack. You can add USB charging. Cool. It's a micro B connector, which I find interesting that it's not USB sweet. You're going to get like the wires that have all of the different adapters on there. Until we get to the all USB world. But there is, I'll put this on, I think a verse. Wonderful. Yeah, folks are picking them up. Slide that in. And then in addition to that, we're just talking about the QT Pi as well. That is different from the Atenel version. It's great. So the red one is the RP2040. Good chuller choice to go with the Raspberry Pi. So same type of deal, except that you have these corners that are hugging on to the board itself. Yeah. Let me zoom in there for you. There you go. So one of the differences that we had to do is if we take this side, you can see the differences in the bottoms. Oh, God. Oh, nice and tight. Don't break your nails. So on the bottom of this guy, you can see the RP2040 chip. And then that's fine. So the quite differentiation from the Atenel version, let's see that you have to solder on SPI flash if you want to have more storage for more programs. So we had to have this little, these little, these called these little elevators. Yeah, keep the board up specifically around the spy chip. The spy chip. So it wouldn't sort of rock around one inside the enclosure. Not really needed for this one. So the height and the elevators are removed or elevators are removed from that one. So it is a little bit more slimmer and sized to fit the RP2040. Cool. You have your little cutouts for your stemma connection as well as your USB-C port right there. Cool. And then they go onto either the inside of the Lego base plate or right inside the tubes like that. Yeah, it's good. They can do either. You can make a nice little circuit without having to use a breadboard. Yeah, this is your breadboard. And the StemAQT connects the sensors. Create a really nice simple project. I just have one here for a display. This is the, what is it, the STSHT31. Is that a temperature sensor? Yes. So I'll put all of these on. Thingiverse, you guys can have access to all these. Yeah, agree. Just an expansion of all of the Lego holders. There's a ton for like the feather and all of the different sized StemAQT sensors. Right on. So that's my prototype. Wonderful. All right. We got a quick shop talk for folks that like the Raspberry Pi and you're looking for a fun case, VHS, cassette tape style case. So it snap fits open. I got my reels that kind of popped out, but you can print out these reels that kind of snap fit into this or you can glue it to the cover. And then this is a no screw, no support case for the Raspberry Pi for model B. Pretty simple. It's got this nice thing at the bottom here to take out the S, the micro SD card. Just kind of neat. Pop that in. You got this nice indentation here for the ports. So USB-C, your two mini HDMI or micro HDMI, and then your audio thing. And then the cover has a little slot here for the headers. And then these cool stylistic holes for a tape reel, a 3D printed tape reel. So check that one out. Really simple case. Really festive. Like is it festive? I don't know. It looks very- People like it. Yeah, people like it. So check it out. It's on our thingiverse, Adafruit's thingiverse page. And we may, we'll probably do a video on it at some point. Yeah, that's not it. Y'all can get to there just Adafruit. And now thanks, swid.jpeg is saying that he literally just got a 3D printer yesterday, and these little Lego mounts will be the first thing to print. Oh, that's great. Perfect for testing out your tolerances, and it's such a quick print. I think it takes 10 minutes to print these. You're ready to- Yeah, those are great prints, these little snap bits. All right, cool. So you can check out that. And then- Yep, Liz is saying that the case is perfect if using the pie as a media device. Yeah, for sure. Shout out, Liz. And then Hugo likes the extra spacing for the SD card reader. Yeah, I really like that too. That was my favorite piece of it. It really makes it so you can like not mistakenly get the SD card. That Liz is saying that you could also, that there's also room to fit a small heat sink on there. Yeah, that was really cool to hear. So it does get hot, and having a heat sink on there is definitely a thing you want to do. So check it out. You can print it in your favorite glittery filament. Call back from Bruce saying, be kind, rewind. Yeah, right, be kind, rewind. That's great. At some point maybe we'll do like a real reels, you know, where they're actually moving. Anyway, cool. So check that out. Let's shop talk. We're going to jump into community makes. We got two time-lapse Tuesday videos and a dozen or more community makes. So we're going to try to do them all. We have about 15 minutes or so left for the show. So let's start off with last week's Kaleido, I'm going to say Kaleido Cycle. Yes, it's called the Kaleido Cycle. I've never seen this, but everybody loved these. It is a print in place by Enrique, who put this up as a free download on Thingiverse. It is just mind-bending. It's one of those really cool fidget toys. For sure. Print in place hinges. It's so cool. And it's about sports. They're just playing with it here. Yeah, so when you're waiting for a video to render or something to upload or... It's like a stress ball, but, you know, sit there and just all day. So I'm using the purple glitter filament here. And yeah, you can see where the hinges for that is. I think I used a negative 0.1 horizontal expansion just to make sure that none of these pieces fuse together. That was pretty much it. Yeah, horizontal expansion. That is a... Bit of a slot. Yeah, there's a bit of a... Is it particular to just Kira? Or do you think other folks use it? Yeah, it's other names. Yeah, it's basically a way to add a little bit of... Or shrink. Yeah, you can shrink your models a little bit. In Kira, it'll look for surfaces that are touching and just add little bits of tolerance gaps, whether you want to make it tighter or loose. And again, that's horizontal compensation. Yes. And then Kira was saying, this is what you play with while you wait for your next print to finish. Yeah, and you can get this print from Thingiverse. Looks great. Thanks, Enrique, for sharing this one. Very, very great print. And a good one to test your tolerances, like you printed on this Prusa. One of the things, the next one, I totally forgot to link. I'll try to maybe link it next week. A little bit too late now. Easter is already over. This is cool though. I dig these prints that have the filament, like these channels, to put in a filament. Yeah, so this is filament. This is just a 1.175 diameter filament. Look, Pedro's popped it out. And that's a great technique. I've seen vases that use this technique where you slide in your colored filament and through the grooves. This was a great little Easter egg. A cool way to do multicolored prints in this nice decorative way. This is so awesome. Think about candy canes. Think about other fun festive treats, like a fried egg. I had to mention Liz's fried egg because I'm thinking about, hey, that was a egg. This is like pre-fried egg. I got a little hole in here for candies or something. It'd be nice to split this in half with some snap 50 other parts. Yeah, that'd be cool. So nice, excellent way to do multicolored projects there. This week's timelapse 2 is a time-lapse. It's a turtle. Yeah, it's a sweet little turtle that doubles as a phone holder. Look at this print though. It's a great day when your time-lapse doesn't have string. Right? What can you say about the timelapse with string? So I'm going to press. I didn't have to use any horizontal compensation on this one. All of the hinges are very loose. So excellent job on getting all the tolerances right in modeling for that. See here, the head moves up and down. You can see where the hinge for that is on the back there. Phenomenal detail. As well as the arms and legs. That's so cool. And here's a little part where you can add a phone. It doesn't work with a phone with a case on it, but it works pretty nice. I didn't show that you can have different angles with it too. So you can have his head or his arms up. Yeah, you can have different angles. It's had a long day. He's going to just push ups. He just laid this massive egg. What do you mean? So it's the metallic rainbow color. So it starts off as a yellow or brown yellow on the bottom and then ends up with purple on top. Cool. So this is a design from Colt's 3D. And I'm looking for the design. I think it's you scroll down. There it is. This is by Kendo Fuji. Yeah. Hello. Check it out on Instagram as well. Kendo Fuji. Awesome. This is a free download as well. Very, very fun. Super cute. You didn't scale it? Are there different scalers? There's no scaling that I did for this. There's nothing that I had to edit. And of course I has that Super Mario aesthetic look. It looks like one of the turtles from the game for sure. There's a little power. I don't think that's great. These photos are fantastic. Like your little scene. So cute. Super, super cute. So check that one out. Flexi Turtle by Kendo Fuji. Awesome. Thank you for sharing with us. All right. Our internet is struggling but we will try to get to the rest of the show. All right. The next part is more community makes. So we got a collection of community makes from folks. So the first one, you know, this one is from Little Jim on Twitter. And she does cosplay and she created the animatronic wings that we put together, redesigned in collaboration with Erin St. Blaine. So she's got her prototype going. And then in the next one, this one shows something that I didn't get to show. Heavy wings. These are dragon wings. And they flutter. And that looks amazing. They look quite heavy. Like the weight of the wings feel quite heavy. The tail too, the animatronic tail in the back. Yeah. That's fantastic. I love those wings. This is actually the route to that we were going to go originally doing bat wings. Right. Dragon wings. Super cute. And then also the tail as well. I'm not sure if it's connected to the servo feathering, but the servo feathering has up to eight servos that you can control. So if you want to have ears, we saw, you know, because it was more aimed towards like fairies. And now it's dragon bats. So that's great. So shout out to Little Gem for showing that. It's fantastic. All right. The next one? We got to do the tail next. Or update our tail project. Right. I think that was the idea is to have the ears and the tail with the wings. Next one is some students doing some brain craft projects. Yeah. So brain craft, like you said, Microsoft, Lube AI. Very cool. Tensive flow projects. Students. There's an orange. It's very cool to see. So shout out to Girls Into Coding for sharing this. I could see the Star Trek case in the background there, that other orange case. Oh, yeah. It could be, yeah. I like the theme of the orange case and the orange. And then a bit of an orange pen. Pen, orange. Oh, cool. This is a great machine learning project. Like definitely check that one out if you want to get your kids interested in it. Sweet. Next up. Another one. This is the Pie Girl. One of the Pie Girls. We've done a few. I don't know which one, sorry. Maybe it's the Pocket one. Yeah, Pie Girl Pocket by Mark Gray game. Yeah, that looks great. We need to get ours back up and running. Have Gavin play the original Sonic. He would love it. Just so we can go through how frustrating it is to get through a level. I remember showing him maybe two years ago. We turned it on and it was like, is it on? I'm like, yeah. It takes a minute to power on. It's Linux. All right, here's another one. This is from Maline. This is a brick head. I'm going to call him a brick head. Yeah. It's Emmet. Yeah. This is a really personal project to me because this is like some Circuit Python code that I wrote. I normally don't write code, but I was able to write this one. And it's a testament to beginners that don't write code can write Circuit Python code, for sure. So this is a brick head. And you 3D print it. No supports. It's got a Circuit Playground in the Stema speaker, I think. Maybe. Oh, I see a speaker up here. Maybe not a Stema speaker. Just a regular speaker. And it lights up and it uses Circuit Python. I thought it made it. Oh, wait, no. Yeah, it is a Stema speaker. Oh, he took it out or something. Yeah, that's cool. And, yeah, you can print this out. Yeah, you can print it in translucent, so it shows up nice and yellow. Cool. And it's super easy to modify the code because it's Circuit Python. So thank you, Maline, for posting that up. That is great to see. You've got another one here from Dan. Dan posted this, his make of the Guardian Sword from the Legend of Zelda, Breath of the Wild. What's so interesting about this? So this is really cool. It looks great. It's all Circuit Python as well. 3D printed sword. And then somebody commented on his thing saying, like, here's my build. He inspired me to make a little one. So there's Dan and then Matt, or Mac, Mac, Craig, he's like, I made a little one. I love the little one. It's so cute. I want to make one too. This would be great for Gavin. So the settings that he's using here is just 75 percent smaller. Just barely fit on the printer. Wow. Cool. But it's super cool to see that it's scalable, man. Right? So you print the full blade in one piece. I didn't think it would work. You got it, man. You don't need a belt printer to make a small knife. Guardian blade. It's the one for Terraria. Very fun. I like how that community make, like, spawned the one right after it. Like, these two kind of go hand in hand. Very cool. We have two more. Bear with us. Liz posted her make of the VHS, so that looks really great. I like how she labels hers two gig, so you know. That's a good idea. And she did a very special technique here, where she printed the rails first in white, weighted a couple layers, and then swapped it out, so you get that multicolor effect. And definitely check out Liz's latest video, too, on fried eggs. Fried eggs. So you can, you can create a, it's a really good, like, test print, because it's, like, changing the color. It's great for, it's not just that, but, like, it's great for bed adhesion. Like, it's all bed adhesion, so that's really good. Yeah. And it's got magnets, too. So check out fried eggs. I'm showing this as great. All right. That's, oh, we got one more. Oh, the, the, the cyber deck. So make lively posted their make of the cyber deck. And I didn't know that you could flip around the cyber deck, because it's symmetric. Normally supposed to be on the other side, but hey, you can have it on the, on the right side, left side, whatever. It's, it's symmetrical. You can do however you want. But it's cool to see a different thing on there. This is a pyrimony hat of some sort, I think. Y'all know, can tell me what is this? I like the display here. This is cool. It'd be cool to make some sort of bracket that attaches. Pedro, you thought about that as well. You wanted to put like a bracket here to attach this display. Very cool. And great to see different ways to mount this thing. So yeah, cyber deck plate. And the cyber deck isn't stock, right? Right now. Perhaps maybe. Don't quote me. Sign up. Cyber deck, the bonnet isn't stock. Okay. Everybody's getting the hat version. RP 40 for your thoughts. RP 20 40 for your thoughts. It's like penny for your thoughts. And anyway, that is all the community makes we have. Thank you everybody for sharing their stuff. We really appreciate it. And yeah, here's a, hey, there's the fried eggs video. Check that out. Thanks Bruce for throwing that up there. Yeah. The one time that you want your eggs to stick. Yes. So many great puns. Yeah, people scramble for it. Yeah. Right. Oh, we got some more votes here. Susan Lively is requesting brackets for the screen for the cyber deck. Yeah, we're going to do that at some point for sure. We need to make it so it's like all together and contain. Great. Well, that's excellent. What other fun? Checking out the rest of the notes here. So people are scrambling for it. Super fun. I think the next one is to do bacon or something. You print it like a squiggly, right? You print the squiggle and it prints off. Yeah. And then you get all of the different colors. Right. You can swap for different red and salmon. Yeah. All right. Well, tonight, we hope to see you on Show and Tell. Me and Pedro hosted last week. This week, we're just chilling out and showing off what we showed off already. But it would be great to see everybody there. We'll be there. We invite you to be there. You can do so by checking out at 720-ish. Hang out in the live broadcast chat room in Discord and PT will drop in the StreamYard link. Just have your microphone muted before you come on. That's about it. All stuff's fair game. Pedro, your spiel is? Retro tech. Oh, yeah, yeah. Everything. Did you want to show off that you're working on? It could be your kids' project, science art project. Lots of retro tech is commonly shown on there. Nice little nostalgia last week. Also, of course, it doesn't have to be 3-printing electronics. It could be sewing, mortables. Any of that cool stuff is fair game. So definitely show off your interest. It's always fascinating to see that. Then right after that, ask an engineer right after eight o'clock full hour, fill them all, talk about all the latest goings on in the maker community, as well as all the cool new projects coming out and the top secret stuff that Lamar has been working on. So definitely tune in. I don't want to miss that. More mechanical keys, I hope. Yeah. All right. So that's tonight. I hope to see you there. But tomorrow we got more show. John Park's got his workshop. It happens every Thursday. I almost said Thursday. Every Thursday at 4 p.m. Watch too much Dr. Seuss. And then on Fridays, you have deep dive with Scott 2 p.m. Pacific time or 5 p.m. Eastern time. Yes, definitely tune in for all of the latest in the weeds of this or the Python development. Lamar stops by frequently. So definitely check that out. Yeah. I give a shout out to everybody hanging out in all of the chat rooms. Yeah. We did it, everybody. We had the issues and somehow we managed through it. Comments and the suggestions definitely make a difference in the projects that are released. Yeah. We'll do 180s if you guys think we should do something differently. So we'll definitely always accept your suggestions and comments. Thank you all for joining us every single week. I appreciate you putting orders in because it keeps all of us going. Here's a pre-COVID photo. Hopefully later this year we'll be able to meet with everybody. I forgot to give my spiel during the 100 days of masking. We recently got our Pfizer shots on Saturday. It hurt for like two days on the third day. Like it would only hurt when I had my like hand like all the way up like this. Yeah. And it's completely gone out. It was gone like in the afternoon. So definitely worth to feel somewhat protected. I'm still masking. Oh, yeah. Social distancing. Even after we're fully vaccinated. Yeah, but there is light in the tunnel here. And definitely go schedule your vaccinations. If you can. We're going to need some updated graphics from Bruce there on the. Yeah. This would be a great one for like I got my I got my vaccine like right here. Like here's where I got it. That's like the same arm and everything. All right. Well, I think next time I'm going to have to drive so they can get my left arm. Sure. Because all right. Don't get the shot in whatever handed you are. If you're right handed again. Right. Tips from Pedro. All right, folks. We'll see you tonight. But until then remember to make a great day. See you later tonight, folks. Bye-bye.
