I think that's it, right? That is all. Yeah, that's all for the housekeeping. Thanks for sticking in there. We're gonna jump into the show this week's project. Are we ready? All right, this week's project is an awesome UV meter. Yay, so this is a fun collab project with Liz. It is a little mini UV meter. We 3D printed a case and we're using black LED acrylic to diffuse the LEDs. So I don't have it turned on, but it's running a QT Pi RP2040 and a PDM microphone, which is really cool. So this is the case. I have it plugged in here through USB and just to kind of get it going. Yep, let's get a little USB battery bank and we'll charge this up here. Hey, what's up everybody? We'll go back to another 3D Hangouts. So this is what it looks like and it's reacting to our levels. The closer you get to it, the more it'll show levels. So I kind of have a little demo here. This is really nice to kind of pair this with musical projects. So I have here a little kind of music box that we made a little bit ago with the Neo Trellis. I just got some samples here. So you can use this with all sorts of different things, obviously, but it's a really fun visual display and it's a relatively simple build. Yeah, the black LED acrylic is one of our favorite materials to use for diffusing stuff. It all snaps fits together. So we have a little thing in the back here. This is the cover and you have a little hole here exposed for the microphone. Here's how you connect the PDM microphone. It's not actually a Stemma like a I squared C. It's using a TX online, but that's all documented in our learn guide. So you got two different things here. You got the NeoPixel power ground and data and then you have the four wires for the PDM mic and that gets secured here with some screws and the QT PI just kind of snap fits in here. It's all written in circuit Python. Liz put the code together and we'll walk through it in a little bit here. But really, really simple kind of construction. And there's a little grid inside here that isolates the NeoPixels and then you have access to the USB-C port here and it holds pretty well. Oh, I think I, let me turn it on again. I like, there's like a accelerometer here. When you shake it, it like rejiggers the thing. And we could do that all day but that's the little demo. Just let you guys know how it works. You can do any assortment of things like all audio works, obviously. It's really, really fun to kind of have it and play around with it. You get to play it, right? So it's a lot of fun and we've been having, I've been having a lot of fun with it just kind of having it in the background when I'm like jamming out. It's a really nice little visual. I mean, if you're listening to music in the background it's kind of fun to have it on your desk or whatnot but this could be scaled up if you want to add more NeoPixels or make it even smaller or scale it. Yeah, scale it up, scale down. You can just change up the code and just add more NeoPixels and then kind of customize the colors if you want to do different ranges of audio. So that's really fun. Yeah, so let's jump into, I guess, the Learn Guide or should we take any questions if there's any questions? It's just common so far, everybody likes. This is so cool. Yay, yeah. Wolves is quickly asking, can you adjust the sensitivity? Absolutely, you can adjust the sensitivity. We'll go over it during the code page for the Learn Guide. Exactly. And then DeWester says this would be perfect for his pipe boy, the one little pipe boy wearable that John made. That's super cool. That's printing that out. He wants to add that to it. That would be so cool. That would be so cool about the code because you don't necessarily need to have it in this format. Let's say you want to integrate this into your actual instrument or some other display. It'd be really cool to have this in a different part of your project but I've been seeing these light bars on Alibaba and things like that and I've been wanting to get one for myself. They're a little bit smaller but I figured it'd be fun to DIY your own. Use a cutie pie and a strip of Neopixels. So using the strip of Neopixels is really good here because you just wire up one strip as opposed to individual LEDs. So that's how I did that one. Imagine this with like a Neopixel ring or a Neopixel, a different shaped Neopixel. So you can do all sorts of fun things with it. Yeah, and the PDM mic is in the back there. So yeah, you can play around with all sorts of things. I guess we can deconstruct it, maybe take it apart, should we do? It looks super cool on the inside to see how the lights are being separated with the grid. Right, let me struggle to get this open. We have tweezers, yeah. So I mean, it has a nice snap fit but you could always use like a spudger tool to pop it open. There we go, and you can see how it works now. So I have this little kind of cover that secures the PDM microphone and the QT pie. And on the back here, you can see the Neopixel strip is a mini skinny Neopixel strip. This is the 144 per meter. So they have that specific spacing there. I have real of this stuff. I really like these Neopixels because they fit in the smallest places. You could swap this out for a different Neopixel, like maybe the 50 50 packages or double the size of these, I believe, right? Or these are 50 50s. I can't remember, sorry. We have any of the smaller ones, the Ultra. Ultra, yeah, but these are the mini skinny ones. And you can see here, you could glue this here, but the grid, the 3D printed grid has recess, a little cut out, and that allows the strip to kind of press fit in there and just lays in there. So the grid is kind of special. I designed, because there's a snap fit nubbin here and here on these sides, this kind of pops out like this at an angle like that. And then you can see it's a little bit flexible because of the way I printed it. So you can see it's just this little bar here. This is the bottom layer. And you can see it just prints up. The reason why I have these open is so that you can flex it and pop it into the case. So that's how that grid works. The Neopixel, I'm sorry, the Blacklady acrylic. I, you could laser cut this or CNC mill it. And we offer a template. So if you want to score it, you can use a scoring tool and then kind of snap it off and print out a 2D template for it. But this is the Blacklady acrylic that we stock. Other places will have different thicknesses. Ours is like a particular thickness and it has a really nice diffusion look to it. It's not too dark. It's not too light. So let's go ahead and plug this back in without the grid. And then just kind of look at the thing. I need some audio here. You can't really see it because of the way it is, but I have it set pretty low. Like I have this 0.1 brightness, but you can kind of see it there. So yeah, this is what the diffused LEDs look like without the grid. Big difference, right? So definitely the grid is very useful in this case. So let's see if I can place this over here. I need somebody to talk. Hello, hey, what's up everybody? I'm doing a test here. Hello. See how the magic is. It's like magical. And of course, the more distance you have the more kind of soft the diffusion looks, but press right up against it. You can really see those grills, those lines defined there. So yeah, so that's my jam, black LED acrylic. You got your grid. I've done so many projects now with these grids. Those two in the back there kind of show that off where you can 3D print a grid, a different style of grid. So yeah. So that's a quick look at the construction, three printed parts. Let's go ahead and put all this back together. You want to start with the cover. The cover has a lip here. So you want to put your black LED acrylic with the matte side down, shiny side up. So it is a one-sided thing. Just press that in. Clicks into it like that. Nice, nice. Next thing is to grab this guy here and you want to have this flat surface facing down and these open fins facing up. Just going to press that in there. So now it's in there. That's a little bit of a loose tolerance in there so it's not too tight to pop it in and out. So then the next thing I'll do is I'll wrap this. You see there's a notch there in this cover and that's so that you can wrap this around there just like that. And the idea is that you want to make sure that this case, you see that hole there? That's for the USB-C port. So this is incorrect. So let me rotate that just like that. And now I have my USB-C port facing the correct direction. So I'm going to pop this, let's unplug it for a second. And what I recommend is like kind of lining this up first here. Have I done? Yeah, as long as you get this kind of in there, you should be able to just kind of press that in. A lot easier to install than it is to take it out, right? Okay, so that should line it up. Like it just kind of lines up on its own. There you go. You can see it lines up pretty good. Hey, what's up? Hello, hello. Testing, testing. All right. And then this guy here, just make sure that that hole lines up with the PDM microphone there. And then just push that in there firmly. And there you go. There is your light bar. Simple construction, easy to take it apart, easy to put it together, even easier to put it together. So that's a quick look at it. You could make it thinner if you want. You could reduce the height of the grille, but I find like this is a, okay, that's nice. That's fine. But you can play around with different sizes and things. Yeah, everybody's saying thumbs up to DeWester's idea of adding it to the pit, boy. That would be cool. And then Yanni is saying that this would be excellent for like a little DJ project. Yes. It's like a GIF. And I'm posting, what's his name? Rex from Galaxy's Edge. The DJ guy there. And then Mr. Mystery is saying this is a really good double split experiment. You know, the light where it splits. There's a lot of way to do that. Sorry, I'm just. And that's a good commentary from DeWester saying, this is like magic. He says, this is so cool. Yeah. And again, the DeWester saying that the magic is a, where you watch explaining the future. What's his name? I know this dude's name. Ah, so watch that too. Explain the future? Yeah, what's his name? Explain in the future. Oh, I forget his name. He's a, he's a, English fellow. Yeah, English fellow. But he's just explained how, when you talk about magic, it's not understanding technology. He lives in a world of magic. Even when you understand it, like every time I go through like the, you know, see the peppered ghost effect, like at the haunted mansion, you know how it's working. Right, but it's so magic. But when you're watching it, it's still like so magical. Yes, Chris Barnett. Yes. Chris Barnett, yay. Like every time I go through a figment and you see that freaking butterfly disappear, you know there's a mirror there, but it just looks so clean. Oh, it looks good. Yeah, it's a seamless effect. It's magical. It's so magic. Yeah. How? There you go. All right, let's go ahead and jump into the learning guy. I'll take a look at the code requested by strolls. All right. So if you head over to learn.editfor.com, you'll see this is in the latest guide section. You could also search for it. Yeah, so again, this is a huge shout out to Liz Clark. She wrote the code for this one. And the overview has all of the parts listed. Most of them are in stock, I believe. And you can get the black or the acrylic, the cutie pie, our favorite RP2040 board, the PDM microphone, this nice small one, the NeoPixel strip. About the NeoPixel strip, I believe you can get, let's see if you can get a whole reel or a small reel. No, I guess you gotta get the whole reel. There's some of the other, if you want to remix it, you can use some of the more, some of the less expensive ones. I think you get a 60 NeoPixel strip and you can get like a one meter for like $25. But experiment, if you have your own NeoPixel strip, LED strip, you can adapt it. I imagine a lot of folks who can adapt this to their own LED strips, because it's kind of particular. But other than that, you got all the recipes here to make your audio reactive NeoPixels. What else? I think that's about it for the parts. Yeah, so let's head over to the circuit diagram, just real quick as a visual representation of how the components are wired up. You just got three wired connections for the NeoPixel strip. You got four for the PDM microphone. I like the PDM microphone here, has the built-in four pin SHJ-ST connector. It's, we don't want to call it Stem-LQT because that would imply that it's I squared C. It is not art squared C. It is a couple of pins, head clock and data here. Yeah, so that's how that's working. And you can reference the wiring diagram if you're adapting it to something else. All right, over on to the CircuitPython page. This is going to walk you through installing CircuitPython, the latest version of CircuitPython on your RP2040 QTPy board. This just walks you through getting the boot loader loaded. And then just dragging and dropping the UF2 file to update and install CircuitPython. So yeah, this just kind of walks you through every little thing if you're new, you want to walk through the whole thing. But if you already know the song and dance, you can just get right to it, to the coding part. All right, here is the code. So it is available on GitHub. You can use the project download bundle to download all of the libraries that it needs. It's just two libraries, the SimpleIO and NeoPixel, BusIO and Math and a year old built-in to CircuitPython, so that's really nice. Here in the NeoPixel setup, that's where you want to, if you're using a different pin, you want to change that. NeoPixel number, that's where you want to change the number of NeoPixels. We have it by default, set to really, really low brightness because it's a camera thing. But you can get that cranking pretty bright and it'll blow out all the cameras. So here's the function to average the mic levels. So that's all printed out here. The sample rate, here's how you're setting up your audio microphone, so you haven't done that yet. This is what you can use. Here's the variable to hold the previous mic level. All the comments are here, so folks that are new to code like me can read through it and try to understand what's going on, but this is where you want to change your colors, so if you want, so each NeoPixel is kind of defined here, so that this is the array for like holding the colors. So if you want to add more colors, this is where you would want to add your color arrays. And if you want to use like the NeoPixel library, the LED animation library, you could make it so that these colors are pulling from that, but we figured it'd be better just to kind of just use the NeoPixel library, not the LED animation library, but you could do that. So in the loop, this is where you want to change some stuff out. If you want to change the range under the magnitude value here, this is where you can change that up. And yeah, while you're on that, quick question from Mike P, could this be extended more like an equalizer display? So I'm guessing each one of these would have like one for base, one for treble, one for mids. Or would that be difficult to extract the certain ranges? Like is there a way to say only these low frequencies and only these high frequencies? Not with this particular one, because I think we're just taking like the average of like the total input. So it's very, very simple in that term. So if you want to do that, take a look at one of the other audio visualizer that we made with the LED matrix. And that code is a little bit more advanced, but if you're comfortable with that, that will, that shows you more of a spectrum of different audio frequencies, as opposed to just the general, you know, audio level that we're pulling from the mic. Yeah, so it's a real simple way to kind of do this, but it works really well. Yeah, so check out the code. There's a nice walkthrough if you want to get a breakdown of all the things here. Liz did a great job commenting and breaking it down. So check it out. Any other questions before I jump into the CAD stuff? Let's see. There was one more. Could these be daisy chain together if you had a male on one end, a female on the other? Yeah, you could daisy chain new pixels and separate them with a cable. Yeah, just connect the data out to the data in on the next strip. You could do that. Or you could have, you know, different new pixel objects. Let's say you want to do one that just does highs and one that just does lows, then you would want to get a little bit more advanced there, but you could do it. All right, on the CAD portion, that's where you can download the source files. So if you want to modify this, you can edit this in whatever CAD package. We have a step file with the original bodies and components, sketches, and we also have a Fusion 360, which includes like a timeline and all that for the parametric stuff. We have the STLs as well. You can just download those fairly small. You're gonna need a printer with at least 120 by 120 by 100. So a small printer should be able to print these fine, as long as it's 150 millimeters, keep or take. Now for the acrylic, it's kind of difficult to cut acrylics sometimes if you're not set up for it. You can just kind of score a piece and then cut it. So for that, we have this little PDF template that you can print out. So I figured I'd write the actual dimensions of the piece of acrylic just as a sanity check. When you print this out, you want to make sure it's not scaled when you're printing on paper. And then you want to follow those outlines. You want to cut inside the outline. I made that particular because sometimes when I'm making templates, I like to cut on the inside of the stroke, but you can change it up if you want. If you have a laser cutter, awesome, that's great. You could just throw this SVG in there and cut as many as you like. It's an SVG file, which is the most supported file format for laser cutters, I believe. So you can take that and cut as many as you want if you want to make many of them. Yeah, I put a little CAD animation together just to show how the pieces fit. So here it is, all the pieces. I kind of showed you live on the overhead, but here's how the pieces are fitted. You got the PDM mic secured with screws, the QDPI just snap fits, and then everything just kind of sandwiches together and does a 360 barrel and explodes again. All of these CAD files, like 3D models of the QDPI and the PDM microphone are all available to download on our GitHub repo. And they're also linked in the respected learn guides of the product pages. So yeah, there's the QDPI design source. I always have a link here to our GitHub repo and you can find here all the parts. The way that you can browse through them is use the product ID. That's what these numbers are, three to four digit code. So if you want to just search for the PDM mic, you just type in PDM mic, control F. There it is, the PDM mic breakout. And there's a little GIF of it with the built-in JST connector and all that. So it's really helpful to have a 3D model of this so you can get an accurate representation of where you need to expose your microphone and those mounting holes are awesome. I love me some mounting holes. So there you go. Very satisfying animation says Susan. Yeah, sweet. They're my favorite. All right, I guess we'll run through the wiring real quick. We're just setting up the four pin cable. I don't want to call it a stomach cable because we might confuse. So I got to call it a four pin JSTSH cable. You want to cut that, right? I'm using this cable with those male header pins that are not actually used because you need to solder these wires into the pins. So I cut it down and it should be about the length of the acrylic. So it's about 114 millimeters. First up, I like to wire the JST cable, the four pin cable, to the QT-Pi. So I got that there. Just a reference like colors, red wires, voltage, ground is black, yellow is TX and the blue wire is whatever data pin you want to use. In this case, A1. But I really like that the mic has the, you can easily disconnect it. So that's really fun. For the NeoPixel strip, you got to be particular on this one. 16 NeoPixels is what's used. So you want to triple, double count them when you're cutting it and you want to locate where the data input is. A little bit difficult to see on these mini skinny NeoPixel strips, but you can just make out the arrow and I kind of show you here, you can reference the capacitors and the pads to kind of figure out where your data in is. For wiring up the NeoPixel strip, I'm using a three wire ribbon cable. That's, I like the 10 wire ribbon cable because you have 10 wires to play with and you get the satisfaction of peeling it like string cheese, which is oddly satisfying. Yeah, so I started that up to the back of the NeoPixel strip. A little bit difficult to do that, but it just works out better for the assembly. Like once you're stuffing it in the case, it actually is better if your wires are soldered to the back of the pads as opposed to the front of the strip. So I have these little labels here. You can always click on a photo or right click on it, say open a new tab, and it'll open it in its original. You can go to the original size, which is crazy large. But yeah, you can see here that digital in is here, ground is up, five volts is down and then when you flip it, it's reversed. Just when you flip it, you can see five volts is up and ground is down. So again, that's just so that it's easier to fit in the case and a little bit difficult. I mean, they're really, really small pads, but this is the highest density you can get for these mini skinnies. Good soldering practice. Yeah, for sure. You want to get even smaller. The ultra skinny. Yeah, it's so small like you have to like use the back and the front. Yeah. All right, well, once literally the power is right on top of the ground on the other side. So be very delicate and intricate. Use tweezers, I recommend tweezers and helping third hands. All right, so once your new pixel strips lined up or wired up, now you can wire it up to the cutie pie. You're gonna have to share the ground pin because there's only one ground pin, but that's what you got. Wait, yeah, there's only one ground pin. So you got to share that, but it's cast-a-lade pads. So there's plenty of room there. It's actually two. You can fit two on there. One on the outside, one on the inside. The cold itself. All right, then you wire check it, make sure it runs, plug it in, make sure it's taking the audio and everything's connected properly. Coach should be already uploaded at this point. That's how you organize the pages that way. And the last page, stuff in it all in the case, the assembly page. You want to start with, I like to start with the PDM microphone, securing that with those M25 screws and some heck nuts. Really easy to mount that. Just follow the photos for the best orientation. Plug in the PDM mic, snap fit the QDPie. I've shown this before how to install it. You kind of flex it a little bit so that the, insert it down an angle at first to the back of those little corner nubs. So you fit the PCB under those little clips and then once it's at an angle, you can use your other hand and your fingers to kind of slightly flex the cover so that the QDPie, the corners of them in the front can fit, like such, like that. And that makes it really nice and secure fitting. After that's installed, you can start putting the LED acrylic into the case with the shiny side up and the matte side down. Then the grid gets installed with the recesses facing up because that is where the NeoPixels will rest. So then you want to wrap the NeoPixel strip on the back of the strip cover, then lay it down on those recesses in the grid and then just, as you saw in the demo, just press that thing right in there. But make sure that the USB port is facing the use because I have done that where I like put it in wrong and like, darn it. And then again, I mean, not again, but the last bit is to get the cover, just line up the cover so that the hole is lined up with the microphone and double check your USB-C port is there and you're ready to rock. Plug it in, use a five volt power supply and you're good to go. And that is the whole guide in a nutshell. Check it out. If you make one, please share it with us. We'd love to see your build or remix. That'd be really, really fun. So now I will, how did I do it? And before you do that, Charles Bennett Ford is saying that you could use the fast for your transform to get info for the EQ. Oh, what? Fast for your transform. Wow. Yes, I hope to see more folks do excellent stuff with it. Which is the Circuit Python library for, they call it FFT. That's right. That is what is used in our LED matrix audio visualizer. Yeah. I was trying to find that, FFT, and the... That's the frontier learn. I think that's what Lamar wants. Yeah, it's called like audio visualizer. So, frontier. Oh, here it is one that John made. For the trellis for this guy here. I'm gonna link that and then... Oh, that's cool. Yeah. Philip made one. It's Philip, I guess. Made one as well. Yeah, this is our one. Philby did one version of it and Liz did another version of it. Oh, okay. But yeah, this is the water spectrum waterfall stuff. So, totally you can adapt that. I don't like it. Remember to post that one. I'm gonna post links to all these visualizer. Yeah. Yeah, so this was some FFT example waterfall spectrum analyzer by Jeff Epler and Liz adapted it to work on this particular hardware. This LED matrix is a 13 by nine RGB. That's really fun. Use your heat map, codes, codes, codes. What was it called? This is documents as well. What's up? What's the name of this? Mini LED matrix audio visualizer. Colorful light audio spectrum. There it is. It's a really small one though. It's like smaller than, yeah, it's eddy, eddy. But it's really fun. We have this one in stock too, the LED matrix. What's going on, Safari? It's so slow. No. I have to use Safari just because, anyway. But any hoodle, you got options and folks are starting to brainstorm, which I'd like to hear. Some really cool ideas for this. Yeah, very, very cool. So, you have plenty of fun audio visual projects, new one added. Oh, cool, we still have a dedicated FFT guide fund with Frontier by Tony Nicola. So you can get real deep dive on that if you want. Very cool. All right, and that is the next project. Any other comments and things? We'll catch those, but we're gonna move on to what are you prototyping? Let's see. Let's go ahead and jump into this week's prototyping. All right, this week, prototyping some fun new things. All right, so Elgato release is a really cool foot pedal. We got PT's attention and they're like, hey, go ahead and remake that. So this is a remake of the Elgato foot stomp. What is the name of it? Yeah, it's a foot controller. Hold on, I got the website loaded up here because I'm straight up just copying the exact shape of it. Stream Deck pedal. Stream Deck pedal? Yeah. Everything will have, everything goes better with an audio. Yeah, so this is just a foot pedal. We got three buttons on the inside if we take a look on the inside. You can see that it has one of the little microswitches. Yeah, these are fun. Just attach to there and there's gonna be a cutie pie inside here. Let me see if I can open this up without breaking anything. You're good. So a cutie pie goes in there and then we just have three switches on each side. Right. We've got this nice little way, little divots that go on the little- The hinges. Hinges here. Yes. And one of the things that you know, figured out after creating one, I think you have it here somewhere from a couple of years ago is that we didn't even need a spring. You just rest right on top of that. Yeah, the spring's built into the switch. Yeah, exactly. So just using the pivoting on these, it'll just go on there and pivot right into the button. So that's the idea of it. I think it's like the second prototype I forgot to add. Things like the holes for the USB cover. So when it goes down, it'll cover it. And yeah, pretty much it. Figuring out what decals or logos to put on there. And this'll be just a nice little foot switch which everybody in the house wants to use already. Like my wife was like, oh, this could be perfect for doing the stop and record buttons or taking pictures. Yeah, hands-free. Yeah, she's always gonna send with her hands for nails and stuff. So you can't really go out and touch your phone while you're curing UV nails. So a nice, simple way to have your phone or camera being activated by just having your foot. And what was cool, I don't know, the way that the marketing for the Elgato folks got it really down was just having the three buttons in all the different ways that you can use it for. So super cool way to have a hands-free actuators for your projects. Right, Liz and I were chatting about it too. We were excited to try using this as a MIDI controller. So if I do like expressions, like I think it'd be cool to jam it out and doing velocity while I'm like doing a drum roll or doing some, just activating different MIDI things, the facts, obviously. But I know, taking it from a music perspective, this would be a really cool add-on to whatever you're playing. So yeah. Super cool. Yeah, so that'll be next week's project. And if you guys have any suggestions before, definitely incorporate any use cases you guys might have. Yup. Hope that's not from the chat. I was looking at the Slack, the arcade button one. That's what I wanted to use, but I don't think it's ready yet. What's that? The arcade stemmer board. Right, yeah, that'd be cool to use that. But now you have enough pins on the QDPI. I think the QDPI is a good choice for this. If it's going to be USB MIDI or USB HID, QDPI works really well. It's got all the built-in flash. Let's see. Yeah, Mark Gambler's saying, yeah, really cool, hidden mute on mute button for meetings. That's actually what Jeff was doing. Yeah, I mean, we have foot switches you can buy if you don't want to print it. Yeah, but you're still, it's one of the things that Jeff was talking about. It's a little bit harder to stick one of those inside of the foot pedals that we have in the shop. I think it's like the metal one. You can do it. You just gotta be, you know. You got a tight space inside of there. You need to cut stuff. Yeah. Foot switch. We do have a couple on learn guide. It's just one of the search for a foot switch. I think it's Safari. It's Safari. It's like totally like done skis. It's like, look, man, I don't know anything. But that's what I'm for. It's literally done skis. Like it's like, dude, I don't know at all. Yeah, thanks Safari. All right, move it on. Is that the only thing we want to show for prototyping? I mean, I have the... Really quick. We got 20 minutes. What do you think? Yeah, I have this. I'll have a video of it, but... So the Zoetrope will be in the week after. But the latest update to the Zoetrope is we took different pieces of acrylic. This is thinner, eighth inch acrylic. So we updated our top cover to have thinner acrylic. So that's nice. Also, we've added a ring encoder. So what does this ring encoder do? Well, on the build, Liz thought it'd be a really cool idea to add a photo interrupter. This is the photo interrupter, if you've ever heard of these. It's a way to track speed of a motor without having any smarts. So it's... Well, without the motor having any smarts. So this... I don't have it here, but the encoder ring spins around and it tracks, you know, which frame it's on. So just like this encoder is fitted for this thing, we've decided to use this guy and the ring on the outside to track how fast it's going, but also to change the neopixel color, depending on what frame it's on. So that's really cool. This is a cricket, by the way. This is the builds. You got your motor, your photo interrupter and your neopixel LED. So here's what it looks like in action now. So as it's rotating now, the encoder ring is opening and closing, breaking the beam, as you were to say, of the photo interrupter and that's how it knows when to change the color. So now we have a party parrot with rainbows because that's how the original gif is. And this is a really cool way to do the acrylic animation. You'll see these, but this is a really cool way to have it have the color adding to the motion. Yeah, so it's really, really fun. And that will be two weeks from now. So cool. So that is the update to the party parrot. Zotrope, we've got some smarts. It's a smart parrot. Very cool. Code by Liz, if I didn't mention it. Of course, yeah. And that is this week's prototype. Awesome. We've got those two fun ones. One last comment that I came in regarding the pedal and really good idea by Yanni, saying that he uses it for pasting. Copying. Yeah, that's a really good idea. There's always a time where I have to copy and paste stuff. I'm seeing solder paste, but okay. Oh, yeah. Copy paste works too. Oh, okay. But yeah, if you're doing surface mount soldering and you're applying paste, like a foot switch would be a really nice way to do it. All right, cool. Let's go ahead and jump into this week's community makes. Yay, community make time. All right, every week we find a fun model from the community and 3D print it this week. It's a fun fractal star. Print and place fractal fidget star by Chuck Hillard. It's made the rounds with the inclusion of the quantum filament, which is that two color extruded filament. It looks super cool when you're spinning it around. It looks like it's changing colors from gold and purple here. This is from Matterhackers and I think 3D Jake has the same colors that you can check out. This is super cool. Visually mesmerizing. I really like how you can do the different angles of the pushing that out. And the other thing I show there is, yeah, that little part right there where you're spinning each of the smaller star sections. Let's see how it's, oh, mesmerizing. Ah. Yeah, it's like a joystick. It's so cool. There's no useful, not useful of all, just for fidgeting around. And I love the sound that it creates. Power is a fidget fun. I'm gonna put a link here to that. Oh, does that, I think that one comes off. No, it's gold. I know, it's so cool to be able to do that. We talked about the quantum filament a couple of weeks, part of weeks before. This is one of the things that works really well on where it's like straight lines. And even this looks really cool. You can kind of see that it doesn't have as much twisting as it does with the organic bodies like we were showing where it leaks all over the geometry. Super geometric. Let's take a look at the Thingiverse page. If I can pull it up. Grabbing the link. It's on Thingiverse. Yeah, so some people were asking, where can you get the column part? If you check out the profile page for Chuck, he has them all listed there. There's a couple different sizes. There's like a five point, eight point, different stars that you can pick from. He has a bunch of other really cool designs as well. Should have this loaded. Oh, there it is. That is the column that you're using right there. This one? Yep, and a couple of other different designs. What about the twirly, twisty one? Yeah, that's it. Oh, that's not it? It must be in the Thing files. Yeah, there's several different like unicorn or yeah, all of them are all listed there. The only thing that makes it, you know, kind of jarn is like, oh no, there's no photos of it. Nope, there's a renders of it. That's cool. All right, Chuck. Well, those are built. Yeah, totally mesmerizing. You're gonna want to use the vase. So I used the vase modes, vase mode, and a one without vase mode. You can hear the difference, like a little bit more like the deeper, you don't hear it. You can kind of see it in terms of the thickness. Yeah, I guess you're right, this is thinner. So the vase mode is gonna be thinner. And then this sticker has like three perimeters. So one right in the center and the other two outer ones. But yeah, nice. I'm sure there's some sort of useful way for it, like how we're using it, like joysticks here. I'm sure there's something that you can do. That's useful beyond just having it be mesmerizing fidget. Cool. All right, well, check it out. Nice little way to test tolerances and all that good stuff. And your bed adhesion for such a small little footprint in terms of the thickness of each line. I have a link to the filament from MatterHackers. Yeah, I was gonna just go around there. Search right there. Go ahead and just bring it up real quick just for folks. No, again, this filament is super cool. It's not dual extruded. It's just the way the filament is made. It has two tones to it. So when you print it, it has these two, this cool kind of iridescent effect. So there's a couple of different colors to choose from. We use this purple gold filament here. Get it in both diameter sizes. And it used to be $42, now it's a $37. Pedro, what's up with that? What happened? It used to be 42 bucks, now it's 37. Oh, I mean, it could be the, it's on sale now and it's like more expensive than it was before. I don't know. But you can see here a lot of the gel material they're using. Yeah, you can see here how it leaks kind of in or Gainek models. Check it out. Lots of questions here. Do you have a filament profile? It's the same as a PLA. Yeah, we didn't change anything. It's like the silky stuff. All right. All right, let's take a look at some makes that were sent to us. We have some fun ones this week. Very current one. All right, we have our first make. Wait, this was from last week. I was gonna say, I thought we showed the Tuscan. Then why is it at a date? Oh, it's a remix, sorry. Oh, this is the one. Okay, so it's a little mix up with the amount of fins that we're on. Yeah, I thought it was four fins, but this person said it's three, so I made it three. Which is great, because in Fusion you could just type in three for the circular pattern and it works really well. So Ed Johnson went ahead and updated it so that it has the three fins, printed all the pieces and it looks fantastic. Posted it up as a remix. Wow, cool. And I guess there's a YouTube video. You can see. We'll have to share this on the blog. Oh, nice. That's if I can even. I didn't realize he made a whole video. Me neither. That's great. Yeah, look at that. Includes a secret compartment. Nice. Wampics. That's funny. This is awesome. Wamp rats stuck between your teeth. This is hilarious. I thought they were eating scurriers. And Wamp rats. You got to eat what you can take from the desert, man. Yeah, it's more meat on it. I'm going to have to reprint mine with three fins. Thanks to Ed for it. Yeah, of course. Thank you for sharing it. No, Wamp rats were horrible. Shout out to Ed Johnson for just being awesome and putting that up there. Yeah. Sweet. Yeah, I love how Prusa allows you to color your model assemblies. So here, Ed put this, colored all the STLs and brought it in here. So you get it really nicely. This is way better than any of the other CAD. Well, it sounds like huge. You imagine, remember? You imagined it that young. Maybe this is the same sort of thing. Solid. What else can you do? Yeah, remember, I allowed you to change the colors and then like... And it's a 3MF, so that's why it's allowing you to do that. I hope you were saying that the full-screen video did not show. Really? Sweet. Solid. It's in Ed's post here, so we'll be sure to post it up. Okay, trust me, it was cool. All right, so shout out to Ed for their Tuscan Chief Staff Remix. All right, next up we got another one here. This is another remix, I believe. If you have a feather and you want to make a generic enclosure, we have a little feather case. And now it's been remixed to work with the USB-C port. So this is one of the RP2040 feathers, I believe. This was posted up by Maker714 on Thingiverse. It says, it's a remix of the feather. No tab case with the updated USB-C port to replace the micro USB port on previous feather boards. Very, very nice. This predates, yeah, 2017. Predates some of the feathers, but nonetheless, good to see folks updating remixing it. Okay. And this is another huge awesome remix build by SKKaw posted up their build of the Dark Saber. Nice. This is epic. It's bigger, longer blade. So there's a hole right up here and it shows, kind of walks you through all the steps of how they put theirs together. They printed the smaller blades, I believe, but also made it bigger, right? Venturing into electronics and programming, walks through wiring and everything. This is really cool. It's like their own build log of them building it. Here's the, when they get the circuit up and running, it feels so gratifying to get your circuit and testing it out right before fitting everything into the blade. It's like really fun. Wow. Oh, that's so epic to see that. All your efforts, like when it turns on, it works. It's like, ah, we're trying to learn. And then building the full-size blades when he walks through his post-processing. Oh, he did some poor post-processing on it. I think it's post-processed. But here's the, so they remixed it with a bigger blade. They have one, two, three, four, five sections. Mine's only two. This is five seconds, so it's a lot longer. And super easy to adapt, I guess, and get. And here is the longer blade turning on. Super long video. You know, portrait mode looks great. Oh, I mean, it's portrait mode is kind of made for things like this. So this is really cool. So it's been reinforced with polycarbonate on the outside. So you can see here that these pieces, you can get them built by Pinoco or whoever else, the laser cut them for you. That's kind of how I started out. I was hoping to make it out of acrylic, but ended up printing the blade. But acrylic side panels works really well, too. Yeah, that's really cool. So reinforce it. And here's a couple different colors. Shot, and that's it. Yay, this is the way. Build it yourself. Very, very cool. I wanted to show real quick the latest updates to my dark saber. Maybe if folks want. Yeah, it's very current. All I did was I continued with glitter filament. That's all I've done differently. So it looks great. Like the handle looks great in glitter. You can see there, you got lots of texture to something that otherwise looked really, really dull. Still like that black LED button. What else can I say about it? Yeah, it's very, very fun. Print one today. Yeah, make yours today. Make any modifications. I know we were watching episode six before the show started. We were like, oh my God, there's so much of somebody. Yeah, that's why we put Grogu up there. Oh my gosh. So let's finish the show so we can watch the rest of it. Okay, so shoot shot it again to SK Ka for posting this up on their blog. I'm gonna post this up as well on the Aderford blog because it's fantastic. I got like five minutes to go through. It's kind of quick. We've got the 16 by 16 Neopixel Matrix Display Make. Yep. So if you want to make yourself one of these lovely displays in the background here, you can make one too. We didn't do a learn guide on it, but we do have the 3D models available. Thinkiverse is an awful site. It's an awful site. I'm so sorry. What are they gonna come at me? Nobody works there. I'm so bad right now. It's just that I can't share it. I have to like pre-record these now. All right, it loaded. Calm down. Everybody's fine. So here's, I am Burr's. I'm Burr. I'm Burr. I'm Burr. Thinkiverse user, I'm Burr posted this up and that's their make of like, look at the image. Looks like it's a fire. Yeah, it looks really cool on fire. Cool. Excellent. Yeah, so if you wanna make your own, you can make one of these 16 by 16 square pixel displays with black LED acrylic. Very nice. Nice. Sorry, I'm trash talking. Thinkiverse, apologize. That is not the way to trash talking. Thinkiverse. And then last up is this really cool Highland Shield. Highland Shield posted by 3D print. No Visha, one piece. It's fantastic. I need a time to do that again. Yeah, on the enders. You kidding me? That looks great. some reports at the top and see if there's any comments you know but it's a great post ours was printed in two pieces on the type A machines back in the day but this is cool that's beautiful yeah and while we're here on the website on prison printers I'm on level 16 what's the highest level I don't know but I really want to get me like a hat or a hoodie and I encourage folks to post makes and comments and all sorts of fun things if they just want to send us one hey small voting every week yeah first friend is a great site check it out if you potentially can earn some cool stuff and it was I'll tell you one site anyway I'm done all right that's it we're gonna be hosting show and tell later tonight yeah shots everybody posting their makes by the way really really appreciate it it just makes our day when folks stuff will make it's so cool makes us makes us feel like hey the thing works thing works and people are doing it posted up it doesn't work too so this week we're hosting show and tell so we're hosting tonight so we invite you to come on 7 30 p.m. Eastern time that's when we do the show and tell I'll drop a link in the discord chat rooms so folks can join in we'll have some special guests from did you key and maybe more but don't forget I forgot today at 3 p.m. is a special hack chat on hack a day with Adafruit team Adafruit talking about floppy drives in their progress in circuit Python and their journey yeah so cool got Jeff Lamar and Phil on there talking about how to copy that floppy yeah so preservation Adafruit will be live streaming but it will be done through a text-based chat through the hack a day website we'll still be streaming the will be streaming the text chatting will be streamed as well on our channels all over and look at this fantastic photo by Phil yeah fantastic don't tune in for that lots of cool insights in that and later tonight yeah and then later tonight like we were saying we'll be hosting show and tell come on stop by get on the discord at discord at gg slash Adafruit will post the stream yard link for that come on and show off your awesome project awesome intergalactic planetary and then right after that she asked an engineer law and fill at 8 p.m. Eastern time and look at all of the cool stuff going on background and new products looks like we've got some new solar panels in the shop super cool yeah I forgot to share on shop talk yeah we got two minutes all right we'll share for next week but thanks everybody for tuning in we really appreciate you folks joining in live and folks on the archive if we get the other shows tomorrow got John Park's workshop Thursday 4 p.m. Eastern time we have deep dive with Scott yeah I think he's already announced but pretty soon too we'll have Tim foamy guy who will take over yeah Scott I'm gonna take over but it'll be a well once lovely addition well he's gonna he's gonna go on vacation for a little bit and that is when he will fill in Scott's shoes for some awesome streaming a circuit python does that on his own channel right now if you guys want to check that out please subscribe to foamy guy and so cool on YouTube get in the weeds of some yeah projects in as he makes them I was watching him work on a win amp yeah so cool super dope all right well that's gonna do it for this wait did we do all the things then on a weekend weekend is just a lady Ada usually on Sundays around 8 to up to like midnight the start time not that long that's right Monday's circuit python meetings every Monday at 2 p.m. Eastern time then Tuesdays is JP's product pick of the week every Tuesday at 4 p.m. Eastern time you gotta tune in live to get those 50% off the discount code was huge it was a $6 feather RP 2040 you can't find that anywhere like the freaking Pico is like $5 and it doesn't have any of the goods like built-in lipo charging and anyway so yeah shout out to John by the way it's John's birthday oh yeah yeah happy birthday John yeah I'm gonna have to like do a little do a little birthday to Ernie so I have to do something on the don't tell John special little song for him but that's how we do it here at Adafruit thank you everybody so much for joining us we hope to see you tonight if not until then until next time good luck with all your maker endeavors and remember make a great day a great day see you later at night bye folks here's some music
