Heading on over to the jobs board at jobs.adafruit.com, you can find all the latest gigs that are available. If you are a maker or an employer, you can create your profile or you can create your listing. I'm taking a look at it. This week we have a new position, looks like, from Evil Mad Scientist in Sunnyville, California. There's some great folks over there looking for manufacturing assistant and some multiple openings. So if you are in market for a new gig, check out the many great positions at jobs.adafruit.com. They are awesome. We have like hot pot or something with them. I actually clicked on them. I'm actually interested in department time, fabrication, I've got a friend that's looking for something, so yeah. Very cool. They even have all the description looks very lovely. So check that out if you are in the market for a gig for some special folks. All right. And that is the housekeeping this week. We'll jump back over to the Discord chat room and catch any banters, gifts, any big gifts. Good morning everybody. I got gifts for you today. I have two gifts. And he's scared that Lars might be hiding behind the screen. I haven't even. I'm ready to jump out. That would be really tough and awesome, if like you like to go over that show. Wow, gotcha. Hello. That would be really funny. We should chat with John to see if he can make that a thing. Special guest Lars. He like does a layer by layer. Lars by Lars. Lars by Lars. Lars by Lars. Yes. Let's go ahead and jump into this week's awesome project. I'm not quite ready yet. Give me a second. You got your links and things? Yep, all the links are in. All right. All right. When your prototype goes on, I'm going to hit the reorder button. I'm kind of first of situated. All right. This week's project, I think we're ready for it. All right, folks. This week's project is a fun collab project with Liz Clark. If you can go head on over to learn.adafruit.com, you can find out the latest guide here is our party pair, Zotropes. So this takes the idea of a Zotropes and makes it a little bit different. It uses edge-lit acrylic and some 3D printed parts. And the Cricket, the Adafruit Cricket Featherwing with the Feather M4 to make a pretty cool Zotropes. What is a Zotropes? Zotropes was invented in the 1830s. It's a very old way of displaying animation in a physical medium. So you go to the Wiki Zotropes, which I can do for you, just to give you a quick history lesson on Zotropes. 1830s, it was a printed sheet of paper and there is sort of a barrel with slits and the idea is that you look through the slits and it creates the illusion once it's in motion, when it's spinning, you get the illusion of an animation because the frames are spread across the strip and when it's wrapped around in the cylindrical drum, it gives you the illusion that the frame is spinning kind of like how a camera works. So this was before camera, before cartoon, before animation. This was the way to do animation and it became a bit of a thing. Folks would make their own and companies like Milton Bradley started manufacturing it in the late 1800s and you can DIY your own. We actually have some in the learn system of some more traditional Zotropes. You can see John. This is probably kind of the first ones I remember seeing is one from John Park. This one here where he also used the Cricut and a DC motor to do this. Dano also did a paper-y one. Oh yeah. Yeah, this one was really cool. You can actually print this out right now. Kiddos. A really cool way to showcase animation in the physical space and then just understanding how this effect works and how you can construct your own with paper. So really cool. Also uses the Cricut because it's so easy to get motors and lights and sensors connected to your project and that's why it's using the Cricut because you think Cricut is just the best way to do it. You can do it with other things but we really like the Cricut because you've got so much capability from the board. So that's a quick little Zotrope thing, another thing I wanted to share was this YouTube video. This was actually the Zotrope prints from Milton Bradley in 18, oh boy, what did it say? 1866. So we're looking at gifts from 1866, folks. That's really, really cool. They were printed out on strips of paper and they were available along with this sort of Zotrope thing. So it's kind of cool to see this. The cool thing about the Zotrope is you can have color and do things like that. So where did I get the idea to make the Zotrope? It kind of started with a couple projects ago. We did an acrylic lamp and the acrylic lamp had I think six panels of acrylic and the neopixel animation would just step through them. So when it's doing this LED chase animation, it almost looks like there's an animated effect. So it got me thinking what if we could make that move, turn that on, make a 3D printed carousel and then have these basically the same acrylic casing in a circular thing. So I figured how do I drive it, how am I going to do it? So I figured to 3D print the gears and make it so that there is a gear inside that rotates the cover. How's our audio? Is it okay? Okay. So it's kind of a combination of a bunch of different ideas. Why a party parrot? Me and Liz have done a couple of different party parrot projects and I just had the vector graphics already. So to convert those graphics to be engraved or laser cut or CNC milled wasn't that hard. It was actually kind of easy because we already had the graphics for each frame. And the party parrot frame is only 10 frames of animation so it wasn't too much to trace it by hand. So that's kind of why the party parrot because we kind of already did it and yeah. So let's kind of walk through the learn guide or no, no, no, no, I should probably do an actual thing. So we got it set up here and because of the lighting situation and the way actually acrylic works, you get a lot of reflection from cameras. So one of the hardest things is to get this to kind of look good in the lighting. So let me turn it on. This is a demo. It kind of sounds like a parrot too. Let's see if I can get the, I think if we turn this light off, it really pops out. So it really depends on how much lighting you got. So if you want to make this in an installation or something, I would kind of set up in a similar way where the lighting is very much controlled and you're trying to film it. It's even harder because you're going to get reflections. So like without this reflector here, you just get a lot of, a lot of illumination that you might not want. So that's why I have it set up this way. So what else do you think about it? Let me turn off this again. And I'll kind of try to showcase the, the thing so the top comes off, right? And the way this works is that there are tabs, there are slots rather on this bottom cover and each panel is just press fit it into these, these tabs. Okay. So then the main base of it has the three components, right? So the three of us is the, the, the motor in the metal and the center and it has this three printed a little bit here. So this three printed gear I'm going to have the projector voice this way. You're right. I'm going to just bring everything over there because that's not going to work. So you saw the demo. Cool. All right, so here is the top cover. Now the top cover is modular in the sense that let's say I want to do a 20 frame animation. Well you would just print out this one piece. So there's three pieces here. You have this encoder ring that has these notches and the notches is what tells the photo interrupter sensor. It's basically an IR LED in this T slot format. So if you ever seen our Hula Hoop project that had an IR LED, it can track when things pass through it. This can track when things pass through it. So I have it mounted on the side here because the LED is mounted right there and whenever something passes there, it will be able to change the neopixel. So if I fit this in here, you can kind of see the photo interrupter doing its thing there. So you see as it's spinning, it's able to know when is the beam open right there when it's actually on a frame and when is the beam closed when it's not on a frame. So that's how the mechanism for telling which, which frame, which color to be is working. So it's like that. And it's spinning freely right now because they took off the gear, which is right here. But when the gear is there, you won't be able to freely spin it because the motor has, you know, the way the motor works. You don't want to strip it. So that's why I have it. So this thing is just printed. This is a herringbone gear or something. Yeah, I forgot. But it's able to print without any supports. And I use the plug-in infusion 360 to generate this. Yeah. So the way it's able to turn is like this inner ring has this channel, right? That's all it is. I've actually added some lubricant inside the channel. So this prints out with any supports. And what you can see is there's some little arcs here. And these semicircles allow the wiring to kind of pass through. So it's really simple construction, good amount of screws to secure everything down. You can see that this motor has two shafts. I had to trim that down just so it was kind of flush with this. So you just want one thing there. Yeah, so the T-slot interrupter is right here, mounted here. That way it can track the encoder ring. And the new pixel had to be mounted inside of the framing, because that's kind of how it works, right? It needs to be able to shine the light just through this. So that's why everything else is kind of blacked out. And when it passes over the new pixel, it's able to illuminate the acrylic. So kind of like how the slits are through your traditional zoetrope, my slits are down here, because it allows the light to pass through. And that's what allows you to see it, which is pretty cool. Now another thing that I want to do is this internal gear. I didn't want it to be a part of the top, because let's say I want to make a 20 frame thing. Then I'd be printing the gear over and over again. So I ended up doing was making this gear actually pop out. So it's a press fit thing. And that's kind of neat. So I made the tolerances on these tabs very, very tight. So I don't even want to take them out, to be honest, because they're so well in there. You don't want to break them. But just to kind of show some cleverness here, I figured that since I'm engraving these, I'm going to lose track of what frame it is. So the way that I've designed it is that there's this tab on the bottom of this panel, and that tab has space. So what could you do with it? Well, let's add a number, a frame number, so you know exactly what frame you're on, so you'll never forget. Another thing is that the tab used to be in the center when I first tried this project out, and that looked okay, but I wanted to kind of position it so that the frames are a little bit more out because as I started to decrease the diameter of the main assembly, this panel would start going on the inside, and you just kind of want to adjust it so that you have spacing. So when it's in motion, this kind of flares out a little bit outside of the thing. Yeah, so there you can see the slot. If you are making this, my tonsils are really tight, so I recommend filing this down a little bit, but I really wanted these to not fall out, and I didn't want to glue them for obvious reasons, but it should be like that. And the encoder ring, so it's a three-piece thing here. You got your inner gear ring, you got your top cover, and then your encoder ring. So if I wanted to make a 20 frame animation, I could just update the value from 10 to 20 in Fusion 360 and print out this one piece, and then I can reuse my encoder ring and my gear because it'll take a minute to print. So it's kind of modular in that sense, and this comes right off of the main thing here. Yeah, so let's talk about the Cricut. The Cricut is running Circuit Python. The Cricut comes with different flavors. This one is for the feathers. So the Adafruit Feather M4 is what's kind of the brains of it, and the Cricut just gives your feather the capability to drive motors, separate motors, capacitive touch, a drive thing, motors, a speaker, a NeoPixel. Everything you kind of need to make this sort of really cool art installation. So you wanted to add sound effects to it. You wanted to add capacitive touch pads so that folks can control this. You can go crazy with this and use every little bit of the Cricut, but we figured just three things that we're using, we're able to use the Photo Interrupter, which is an IR LED, you have the NeoPixel LED, which is over here, and then we have the motor, which is just power on ground, but you can reverse it and stuff. But yeah, there's a little 3D printed bumper for the feather, or for any Cricut really, because they're kind of the same other than the Raspberry Pi one. And there's a built-in on-off switch. What's really cool about the feather is you just give it five volts, two amps from a power supply with this barrel jack, and it powers all the things, and the feather, and the Cricut, all in one go, which is really cool. Yeah, and yeah, running circuit Python, which we'll take a look at. Code by Liz, so take a look at that. Oh boy, what else do we got here? I guess we'll put this back together. If you got yourself a laser cutter and you'd want to make it, I would say that that's really cool, because laser cutter is a great tool for doing this many panels. If you're doing it in CNC mill, well, you know. So this just press fits in, stays like that. And the way to get this in to the top, you kind of want to get the encoder ring through the slot first, right? And then you can start to feel your way towards the center thingy, there it goes. And then just make sure your gear, your gears are engaged and you're good to go. Try not to move it too much because you'll strip the motor, which I have done many times. So yeah, this is it. It's about 180 millimeters in diameter. So you'll need a 3D printer that can have about that. They take several hours of print, so you're gonna have to build time. But it was scaled up to a person like it is. You could try to put this all in together, but I really like it separate like that so all the wiring comes out through this cover. So the cover has these openings for the hole to route through. So you can see this wire here has four wired connections for the sensor and I have a little hole that you can barely see there. And then there's the main hole there just to get these wires out. But you could integrate it into a single unit if you wanted to do that. But I figure folks would probably wanna use a different microcontroller so I'd rather not integrate this assembly to specific PCB or whatever, right? You could run this off a nine-volt battery if you wanted to, if you just wanted the light in there. But yeah, we like the... The smart spine. The smart spine, you know, using a encoder ring to tell what frame you're on. Really quick question from Vince, asking, generally speaking, how durable are the 3D printed gears? I don't know yet, but that's a great question. For something like this, it made a lot of sense because this is about 200 grams in weight, so there's not a lot. How much weight? I think you mean by the teeth them being engaged, are they gonna melt if it's going too fast? From my experience so far, no, they're not gonna melt unless you kick it really, really fast. I don't know what the RPMs are, but I guess we could write code to track the RPMs because that's kind of how the demo code for this product is. But yeah, I would be wary if you are pushing more than a few pounds. Yeah, I don't see any. But this is like barely a pound. This is like I said, 220 grams of weight. I don't know how many ounces that is, but it's like maybe it's about half a pound in the freedom units. But yeah, I have another project where I'm using a similar system and really I got this kind of geared system like this. I was inspired by a fellow who, his name is Isaac, and he made a 3D printed camera slider which used this similar type of herringbone gears. And he's pushing five pounds with his 3D printed gears with no backlash. Looks really good. So that's the only other place I've seen it got inspired from to use this gear system. That was a great question. Yeah, like how is it durably wise? For something like this, it's great. And I think if you're doing like five pounds or something like Isaac was with this camera slider should be good too. If you remember a couple of months ago, I think it's been a couple of months now, we're working on a camera slider with a similar gear system. And it seems to be working pretty good. We'll revisit that in the summer, I believe. But great question. Yeah, nice thinking more of wear and tear. And so far, we're not. As you're saying, we're not pushing it. Yeah, because of the weight is like, there's like very little friction. Like when I added the lubricant here, this is the only surface area that's touching. None of this surface area is touching the lip. It's on purpose. So the only friction you are getting is right here in the screw and right here on this lip. That's the only friction you're getting. Because the lip is big enough where this surface does not touch any of these surfaces. Does that make sense? Yeah, sounds like the major load and speed are the more of the factors. Yeah. And the gear is mounted with these screws here. And there it goes. Yeah. The motor is mounted with these two long screws. So the motor is not going anywhere. Yeah. Do you want to see it running here? Should we do that? That's fine. Welcome to the guide. Cool, all right, let's jump into the guide. That's where all the magic is. Most of the parts are in stock. If you want to get the Cricut, you can sign up to get notified when it's in stock. But if you have one, that's awesome. We got the motors, but all you really need is the Cricut, a feather, the T-slot photoreinterrupter, the motor, and the little NeoPixel. These come in a pack of five. These little PCB NeoPixels are really, really great for these type of projects. And the power supply. I really like this power supply because it's got a little potentiometer around it. You can adjust the voltage. And it can go from three to 24 volts to amps. So that's my favorite power supply. There's some screws. I had to link some external screws to McMaster car to mount the motor. You need at least 30 millimeter long screws, which is fairly large. You're gonna have to buy those somewhere. We don't sell them, but we do have M3 kits, but unfortunately it doesn't include a long 30 millimeter screw. The sheets of acrylic are nothing special. You could get some special acrylic that has like a special coating to make it really, really pop with it comes engraving. I get my stuff from eventables.com. They are the folks that make the CNC mail. And you can get it for more ever, but this is where I get it. I get a 24 by 24 inches, as long as an eighth inch should work here. I did experiment with a quarter inch You could do that too, but an eighth inch is nice because you don't have to spend hours and hours milling it. So that's it, yeah. I don't know how many you'll need exactly, depending on the size. So I just put four, you might as well get four sheets if you're getting small, but as long as it's an eighth inch thick, good to go with this one. All right, so those are all parts. Let's look at the circuit diagram. Shout out to Liz for putting together the circuit diagram. We have fritzing parts. If you want to create your own lovely wiring diagrams, Adafruit makes custom parts for fritzing. It's open source software. You can pay for it or compile it yourself. But yeah, that's how our wiring diagrams are made. Nice visual way to kind of reference how all the wire connections are. There are pins on the side of the photo interrupter that has these labels and fritzing, it's a little bit different. So that's why we put labels there. So that's good. It's really, really nice to just be able to plug things in through screw block terminals. You do have to do a little bit of soldering because some of the things, like the NeoPixel doesn't have wired stuff on it, but yeah, I like the modularity of the Cricut where you can just screw things in and plug things in. Yeah, and then for powering again, just a note, we're using the power supply, the adjustable one. All right, onto the CAD files. All this was created in Fusion 360, but we have a step file, so folks can use Blender or OpenCAD. Does this FreeCAD? Folks, do you use FreeCAD? Can you let me know if you can import step files? I will search after the show, but I figured I'd just ask now. The STLs are available to download, you just wanna print them as is. They're all oriented to print as is. No support material required for any of them? Yeah, yeah. You might wanna brim or two on some of the thinner things, like the framing of the cover. But yeah, those are all the parts. There's a good amount of parts. There's about 10 parts. Okay, but yeah, STLs are available in the CAD source as a step file or Fusion 360. The CAD assembly, I figured I'd put this little CAD exposure to show all the pieces fitting together. This is fun, just watching it. Makes a good gift. I expect order, but just to reiterate, you will need a printer with a minimum build volume of 180 by 180 by about 100 millimeters. So if your printer's too small, you could try to redesign it. In Fusion, it'd be easier, I think. But anyway, that's the minimum build volume. So yeah, now the panels, right? So the panels deciding how big I wanted them, really came down to the minimum build volume of my CNC mill. But I had a laser cutter, I would use a laser cutter. Don't have one, but I do have a mill. And the mill's kinda small, it's about four by five. So these panels are 70 by 80 millimeters. That's about 2.76 inches by about three inches. So they're kinda small. You saw them in my hands. They're not that big. But they are SVG files. So they're vector graphics, they're scalable. And for laser cutters and CNC mills, I think that's the format that you wanna use. Yeah, and I also have it here in the learn guide that says acrylic panel dimensions. You can figure out how, if you can print them, if you can cut them out all in one go, try to do that. If you're on a mill and you have a small bed, you can have to do one at a time like I did. But yeah, I didn't cover that much because I think this is definitely better for laser cutting. So yeah, that's the CAD stuff. Next page just walks you through installing CircuitPython on your M4. The Cricut's just ready to go, so you don't have to update that or anything if it's a newer Cricut. So just install CircuitPython on your feather. And then here's the code, the code. Shout out to Liz for putting it together. So yeah, this is all documented. You can see how we set up the different colors. So each color is put in a list here. So we have 10 of them because there's 10 panels. And then we have an array, just to store all those frames in another list so that we can run through them in the loop. You can change the speed of the motor if you want to go slower or faster. It's just kind of hard-coded. So right now I have a 0.3. You can crank it up to one and get it really, really going fast if you want to pair it to just go into super mode. If you want a more slower pair, 0.3 is pretty good. But yeah, you can change around the colors and add or remove frames as you want. So yeah, check it out. It's circuit pythons. It's really easy to kind of change it up, break it and fix it again, right? But Liz did a great job explaining all the things, how it's exactly working. The wiring, you are gonna have to wire some of the components because they don't come wired like the NeoPixel. You just got three connections on the bottom of the NeoPixel PCB, button PCB, their pads. So you can daisy chain them if you want to do it. But we're just using one pixel because that's all you need. And where you can use your jumper cables so that you can just plug those into the NeoPixel screw block terminals on the Cricut. Now the motor comes pre-wired, which is awesome. But the wire is kind of short. And if you want to kind of have your Cricut detached from your assembly like I do, you can just plug in an extension cable, which I have linked here. I have extension jumper cables. They were here. They're probably in the other page. But yeah, you can just connect those in. Really easy to use jumper wires for that. Though this photo interrupter has four leads on the body of the sensor itself. Our labels, positive, negative, L and out. We want you through that. All right, on to the assembly. I start off by modifying the motor shaft. You only need one shaft. This motor comes with two. It's some soft, not soft plastic, but it's moldable plastic. So I just use slush snips to cut off the end. And you can see here in the photo, you can have a little bit left. And you want to use, you want to cut the shaft that has a little nubby bit. The other side is smooth and doesn't have a nub. So that's why I have my motor on that side. Okay, and then the NeoPixel has a special little holder. It has holes in it so that you can thread the cabling through it. And then the top has a little bit of a recess so that the NeoPixel button can just press fit in there. So there's no need for any glue or any screws to actually secure the NeoPixel to the holder. The holder itself does need screws, which we'll cover. But yeah, that's just getting those components ready in their holders. The slot interrupter has lovely mounting tabs. It's really, really great. So I made this little kind of mounting thing that has cap screws. So you put the hex nuts through the three printed standoffs and then M3 screws on top. And that secures the sensor to the holder. Really nice. All right. And then securing the NeoPixel holder to the bottom plate, just two screws and hex nuts. Make sure that the cable is kind of pointing inwards because you kind of want your cables all routing through one thing in the end. Two long screws for the motor and some hex nuts. Pretty easy to figure out what orientation they go. There's a center hole that allows clearance for the modified shaft of the motor that we cut off and trimmed. Yeah, just making sure that the orientation is correct. All right. So we have our three things mounted onto the inner ring. More screws, gets fitted in the center. Make sure that the wires are all routing through those little cutouts that I'm showing. Putting together the top cover. You have three pieces. You have the outer encoder ring. Just make sure that the notches are lined up with the slots for the acrylic. I'm using five screws and hex nuts to secure it down. I cut it with glue, but why do I hate using glue? I always get my fingers glued, even with gloves, I still. All right, and then getting the inner gear installed into the top cover. There's some notches. There's a little groove. You just line them up, press fit them. Tonches should work out. The panels, once you cut them up, I don't really cover cutting them because whatever tool you want to use. Yeah, but the tabs really worked out really nice. Like the tonches for them are nice and tight. You can go counterclockwise or clockwise. It doesn't matter. As long as they're chronologically, the animation works forwards, backwards, inverted, upside down, like it works always. As long as there's a sequence of them in one order or the other. Cool. The framing just snaps fits into the bottom cover because there's a little recess groove and you just line up where your cables are. What else? It's a little bit hard to show in photos how to install the top cover because you have to get the encoder ring through the T-slot, the sensor. So that's why I showed folks. I'm just gonna make sure that it inserts at an angle. That's pretty much it, right? You can use some screws to secure the Cricut board to the bumper. And then connecting everything together. Again, just plug and play. I just plug things in. The jumper is just plugged right into the header pins and the screw block terminals here. So just make sure everything works and plug it in with the barrel jacking. This should just start working. There's an on-off switch built into the Cricut, so just make sure it's on. And yeah, that's the guy. I did a nutshell. Yeah. This is an excellent starting base for anybody trying to do any sort of entertainment with this, a little escape room or any visual effects. Yeah, I'm sure. Halloween. Yeah, cool. Yeah, it's got this kind of, you can scale it up. Think about acrylic, edge-lit acrylic, and yeah, I really think the Cricut is an awesome little board to do these type of projects where you are sensing, driving, and tracking. So that's kind of cool. I haven't done a Cricut project in a while, but it was really nice to just plug things in and get a quick prototype going. Originally, we were just gonna do just on-white LED and then it was like, hmm, I think it might be kind of cool if you could change up the colors and tell which frame it's on. And she did a great job writing the code to make that work in Cricut Python. Yeah, great for like museums, due esters mentioning that putting a Cricut Playground blue fruit on there had some sensors, so like when somebody walks in the room or tempted to change it or something, you have different animations going on. Right, it'd be cool to have proximity where as you are going closer, it is speeding up the animation or slowing it down. You have control over speed as well. Speed converts into the, you know, how fast is your animation going? It's pretty cool. Sounds like Interactivity 4 again, like an escape room or something in a museum. Like it's almost like reacting to you, which is really, really neat. This is just, yeah, the beginning of something I think that folks can really take away. Excellent little base. Yeah, I also want to give a shout out to the 3D Zoetrope project by Kevin Holm. He, a couple of years, in 2018, he had a really cool Maker Faire project where he brought it to Maker Faire, won lots of awards, and it was the first time a Zoetrope had 3D printed elements to it. And then I don't know if that predates the Disney Pixar Zoetrope, that's another famous one. Yeah, just talking about Zoetropes, like I started researching Zoetropes. I'm saying it wrong, Zoetropes. Zoetropes. Or is it Noaetropes? Connor McCurder is saying that they'll check out FreeCAD to see what they can import when they get home. Yeah, I am able to. And then a general question though. I need to know. What does my stuff look like when I import it into FreeCAD? I'm seeing a lot of folks using FreeCAD and Blender, and well, you're using Blender, so maybe I'll import a step file and see what it looks like. What does our structure, like what does our component structure look like? Real quick, just a general question from a foamy guy who's asking, do we have any resources or talks about what printers we use, recommend for other folks? We do not. I just did a quick search on learn and some of the topics that we cover are pretty, like not printer-specific, so just doing a quick search, like how to print NinjaFlex, how to DIY filament, how to use dual extrusion. Yeah, there's some other great channels out there, like all the re-print reviews. Here's why we have not. We gave away 20 printers. Donated. Was it like donated 20 printers like a couple years ago? Sure, was it? Yeah. Right, forget one. It was to Bill Binko, so he was able to like give them out to schools and stuff. Yeah, the robotics team. But all those printers, we gave them away because all those printer companies are no longer around. Well, that's not the reason why. Well, we can't focus on one printer because it might not be here tomorrow or next year or whatever. So it's like a printer bot. Let's look at Lulzbot. Let's look at MakerBot. All those models, we can't focus on any one model because it'll be gone by a couple years or whatever. So I just linked to the top ones that we like right now are the Krillteys. So I linked to the CR-10, V3. That's our go-to, one of the go-to ones. Krillteys that we use. It's Direct Drive. It has the, you can get all these customized options from Tiny Machines and they receive their shipments in from China. They inspect every single printer. They like CNC mill custom parts for it. They do firmware, custom firmware for it to make sure things like your thermal runway is actually working. So definitely check out their printer or the printers that they have for resell. So the CR-3, V3, it's like 650 bucks. Very nice, good deal for a top notch, reliable printer. And it's backed up here by a Paul Cutler saying that. Yeah, they have the V, the Ender. Did you see Chuck posted on Twitter? There's like $200 at, oh boy, what was the store? Oh, Micro Center? Was it Micro Center? Yeah, I see people in the- Was it like Costco or something like that? It's like a big box store. And they had just a palette of like Enders. Yeah, I saw them the, forget what Facebook group- So it's cool to see them in big box stores like that. Especially like Ender because that's kind of the same. It's Krilltey. They make the cheap, Yeah, yeah, yeah, yeah. Affordable printers. I want to call them cheap because they're good quality. They're all metal. Like all the parts are metal. There's nothing 3D printed or even injection molded plastic. So there's lots of community support for these Enders and CR-10s and things. So that's kind of what we went that way too. We're kind of watching the industry and everybody's going this way. So we got our own some and we have experience with them and they're pretty good. The user says that, yeah, his buddy's got CR-10, solid. Yay, I'm glad they work out. Ender, Pro, another shout out to Ender Pro from Dewester. Yeah, the reason why I mentioned metal and injection molded is cause some other companies are still 3D printing their parts and- Yeah, if it works it's fine. It might, yeah. I wouldn't pay a top dollar for something. I want a metal, like metal parts that aren't going to fall apart or like get all bent out or like, you know, heat hitting it, like the sun hitting it, you know, or something like that. Cool, yeah. Yeah, so another one, Ender 3v2, our store is with the, with it being shipped. Yeah, that's why I say tiny machines. Cause- Yeah, they're distributed, if you're in the States- They're in Texas, yeah. And it ships like- Yeah, they QA it pretty good. Yeah, they QA very well. Yup, something's busted. Custom firmware. You know, they have all the parts that are too milled and custom. We are now working for them. Cause we sell their printer now. I mean, what do you want to continue on? No, no, no, that's it. I'm just, everybody in the chat room is chiming in on their experiences with it and yeah. I'm glad that everyone's got good experiences with them. All right, so that's this week's project. I think again, huge shout out to Liz for collaborating with this project. It's really magical. We can come up with fun artistic ideas and- Yeah, we were looking right before the show- Inspiration to folks. We were before the show, we were looking at some Kickstarter ones and it was like, all this crazy- Yeah, I mentioned it. Yeah, I mentioned the 3D one. It's like, oh my God, that's a- Yeah, it's a kit. You can buy it if you want. Yeah, this is- I hope this is a cool- You know, to contribute to the history of animation in a physical form. Yeah, I think it's kind of cool. 3D printing and acrylic and some neopixels. All right, sweet. Let's go ahead and jump into this week's, what are we prototyping? Sure, we'll come back to some comments and things as we go, but Paige's got a fun prototype and I'm gonna order some burgers. Yeah, so lots of floppy going on and Lamar requested some 3D printed cases for the five and a quarter and the three and a half inch drive. So, try to invest on trying to get these as translucent as I could because that seems to be the hot thing now with the translucent cases that they're showing off. One of the things that I wanted to make sure that the 3D printing was able to or wanted to add that you can do with 3D printing is getting all those cool shapes in here. Something that I don't think you can do with either having the molded acrylic like how they're getting. So, I mean, I guess you could do it by like laser etching it on there, but this is all in one go. You got your like ventilation on there. And the one thing I know you can't do is have these stackable little parts on top. So, that's one of the things that she was requesting. So, able to stack the three and a half inch drive right on top of there and we have the same translucent green on there. That looks so good, yay, look at that. So, we have this translucent green. You can kind of see that I wish this metal case wasn't here so you can see. I love how you can't tell if it's embossed or debossed. Like I can't tell. Oh yeah. Like is it extruded or you know? You can, of course with the lighting it definitely brings out like the 3D printing layer lines, but in real life it looks more like that where you can see the translucency behind it. You can really see it on the back of this guy here. You can see like the mechanisms moving. Let me try to get the light angle good on there. You can see the mechanism. Yeah, so that's super cool. You're able to see the inside of that. A little bit closer. You can kind of see all the chips that are inside. They look so cool with the, it's like a little city or something. So, this just slides in and slides out. You can see all the components on the inside there. So, it is a 1.5 millimeters thick and that's the smallest that I could get it to be a little bit translucent without being, you know, where it'll just fall apart. Basically kind of like a vase mode, manual vase mode without actually using the settings from that. Yeah, lots of cool little detail that you can add on the side there. Didn't add as much on this one because it is going to be covered up when you have the drive stacked on top. But yeah, super cool that you're able to get some nice translucent effects with this filament. Look at that transparency going on. No, I know there's like some other- Are any of that kind of fancy post-production? That's what I was about to mention. Yeah, you could. There's the serial and all that. I think it works really well. Yeah, it's super translucent. And again, it's as thin as I could get it without it falling apart. This is one perimeter? No, it's three. It's three? Yeah, three perimeters. Just a regular nozzle of 0.4 stock. Yeah, yeah. It takes, I don't know, I think it's like 11 hours to print the big guy, about six hours to print that guy. But yeah, we're using the geometric patterns on the side of Fusion 360 to create the lovely little Adafruit logo there. But yeah, I was trying to go for that. Oh my God, I forget what year the color IMAX came out. Probably 98. 94. I don't know. I think 98. My son keeps referring to anything old as, that's so 1990s. So that stuck in my head. Is it from the 90s? Probably was. Oh, the actual IMAX. The IMAX ones, remember that they had in circles with all colors and colors everywhere. But yeah, nice little simple project to keep your floppy drives nice and safe. I wanted to add like some mounts for the upcoming hardware that Lamar is designing to be able to interface with these and circuit Python. So I'll add that on as those boards are released. Figure out some way, somewhere to mount these so the board can be mounted on here, like all nicely and enclosed. Do I start saying, yeah, the glass bed? Oh no, something else. I was gonna say, yeah, I did try the glass bed. This is printed completely vertical. So it just prints up with no supports. I did try printing it flat. But because I didn't want to glue all of the sides together, I was like, yeah. And it wasn't as translucent as I wanted it to be. Went with this route, all vertical. Yeah, I'm still, it's more impressed on, I wonder what, how translucent it would be with that coating on it. But I think I'm happy with having some sort of opaque-ness to it so you can kind of see what it is. Do you know the filament name? So, does that have a name? It's like Xyro, something. No name, filament. Yeah, again. Most of them are just like that from Amazon. Yeah, again, that's the other thing, why are we don't? We don't link to filaments. Filaments because could be here today, but gone tomorrow. Sometimes. It's a weird spot that they're reprinting with filament in general. Like the quantum, I'm able to link to that because I think it'll be around for a while. Yeah, but then you see like, it looks like it's a white label. You see other companies coming out with there. Yeah, so who knows. But yeah, nice little. It's like Calpulae, generic. Yeah, but nice little way to add that classic Mac look. I was gonna show off like in CAD, I like how to create these, but unfortunately. No, we will next week. We'll show it, we'll talk about what. It's a paid for plug-in that I just lost access to today. My trial expired today. So. Pay up or shut up? Yep, I will probably redo this with the manual way to do it. So have like the shape that I'm using to create the pattern I'll have it in. There's just so you can manually do the patternization for that, which I did have to do with that wearable with the little glowy thing that I was showing off last week. So yep, that is what I'm prototyping. Nice little way. Oh, embossed too late. Nice little way to just have a stackable set of your old school floppy disk drives with some cool translucency. What's all this new again? Yeah, I just need some drives now and maybe a way to actually power this. I mean, disks, disks, diskettes. Yeah, super cool. Gotta show it off in the, you don't see the. I have a floppy story, maybe next week I'll tell you my floppy story. And that's what's prototyping. Cool, that is what we prototyped it. Nice little throwback to some retro tech. Retro tech in the works. Retro adventures. All right, let's take the comments real quick. What is enabled dictation? Why would I want an enabled dictation? Where would you tell me that during the show? DOS 3.3s, Andy. We kind of did shop talk, I guess we'll take some comments. Yeah, that's what I was doing. I wanted to take Tim's for me guy. He's had good experience with his Lawlsbomb mini for years with having some auto bed living issues. Yeah, and that's the other thing too. Sometimes the components start to wear out and it's like, oh no, they don't have that available anymore, you're experiencing this with the CNC mill right now. They don't have those motors anymore, so. Yeah, it's very painful when you got a machine that outlives the company or outlives the model and you're kind of. Especially with the supply of strength. Stuff is now. The Crealtes, it's all of the third party parts. All those are made for all those type of machines. So you always get some way to rebuild it. Their design is very modular too, you can just add things to the zales, to the extrusions. And then DeWester, give me a shout out to the glass bed, one of the best upgrades he's done. You like the glass bed? We used to love it too, the glass bed. I mean, we use it on the Ultimaker. It works perfect there. Well, that's what we got, really. Yeah, so both. You get really nice glossy finishes on glass, which can enhance your project or depending on what you want. It just depends, yeah. Yeah, sometimes you'll get reflections so you don't want. All right, cool. Let's go ahead and jump into this week's community makes. All right. Yesterday was a lovely, yes, no, Monday. Was it Monday? I think it was. Oh yeah. It was, yeah. That's when we, we were being brandy for Valentine's, went to the fricking app cart and got popcorn buckets. That was our Valentine's. So this is a really cool way if you have an actual gift that'll fit inside, like a ring or something. This is a flower box. This looks fantastic. Oh my gosh. This was all modeled in Fusion 360 and it's a flower that hides a box component on the bottom. Big enough to fit. A little Lego Adabot. Or of course, a ring. That's what it's probably meant for. Looks like he used some special filament. Yeah, I did link it. It's an Adabot and filament. And as you can see in the bottom here, you do get some little bit of leaking with that filament. Like tends to twist around inside the extruder. But other than that, you get a very nice. Reminds me of Spiral Graph or something. I mean, tie-dye or something fun. Flowers do have this shape sometimes. So it's kind of like true to nature in that sense. Cool. So it's all pretty without supports, I hope? Yeah. This is all print out without supports. Just the way that it's all 45 degree angles. So you see all the little pellet, pet holes. Snap into each other. They don't really click or anything. That's cool, Rotity. Oh, yeah, yeah. This just goes right on top. You got your own Zoetrope there. Oh, yeah, you do. It's kind of like a Zoetrope. You can kind of see the effect with the Quantum Filament when you spin it, right? The inside, Blam Adabot. This is a great little, then nice little, the way that the vine on the bottom or the stem is supposed to be just clicks in there like that. And excellent. Just rests on there. Which is nice. Well, when my tolerance was right off the bed, it did click, but after I kept spinning it around. All right, we'll give a shout out to the designer, the creator of this lovely design. Look at how beautiful this other top looks like. Yeah. I should have printed that one instead. That other top, which I still could. It should fit on that same base. You found something versus by Maz and a Turope, aka Rose Moore. Shout out to Rose for putting this together. Oh man, I wish that picture's loaded on there, but here you go. This is related with regular filament, still looks fantastic. And Rose's mate prints. So you can see here, really nice filament there, and it speaks. You can adornish it with some more things. And Rose puts together a nice CAD video. Excellent Fusion 360 video on how to use the sculpting tools to model out all of the pedals. And I definitely gotta go back and watch this, because this is a, should be some really good tips. Yeah, that's great. Stuff like this that like, I was starting to go into blender, but then you see. What a great project to learn how to really find the sculpt tools. It can be a little bit challenging. I always check it out when. Well, the main thing for me, maybe they fixed it was when you, you're sculpting stuff and there's like no timeline. So you mess up, you could just start all over again. Cool. But next little walkthrough on setting that up. What would be the project? Yeah. How good that looks. This is excellent. Sweet. Oh, there's how you can set it up with a ring. So you can have, I think that's what it's for, to fit a ring box on the inside. Little, whatever those things are to hold the ring in the center. Sweet. That looks all beautiful. Cool. So you get, you can print and yeah, shout out to Rose. Yeah. I was going to release it yesterday or Monday or whatever, whenever Valentine's was Monday, right? 14th. Yeah, it was Monday. But it was like, then I'll be out off schedule and whatnot. But there you go. You can save it for birthday. Valentine's week. Mother's day is coming up. Yeah. Mother's day would be cool. There you go. Get your mother a, a fun quantum printed thing. Oh, it just prints, it just catches itself here. Yeah. Sweet. Very, very sweet. Yeah. You just want it like that. Fantastic. Yeah. These are special limited edition pins for eight a box users. So if you have one, you got the only one in the world. It's kind of, we're never going to know how a lot of things are turning out. Unfortunately. These are NFT. Nice freaking tee. I don't know how bad it means. How good that looks. Like I should have came up with like a cool name for the Zotrope, but I got nothing. Sorry. Trying to show the side of it. Yeah, it looks great. It looks really good. With all the petals flaring up. And that's this week's Commuter Day. Super awesome time-lapse Tuesday. We've got some more community makes that we're going to run through because we've got to do the thing where we eat. Food. This one just came on. Right before the show. Huge shout out to Remy. And Tal. Oh, this looks so good. Todd Bot. He has been doing some very fun, very cool musical sample based stuff in Circuit Python. So you can kind of create a sampler. You can kind of trigger different samples together at the same time. And Remy who built our Pico, Raspberry Pi Pico midi fighter project. Remixed it and kind of wrote an example sketch that kind of does it, with the hardware here for the Pico. So this is not midi. This is playing real audio samples. Okay. Like now you're understanding, right? Like this is playing. That's why there is a audio jack coming out. That's what that is. Because there's literally samples on the board, which is, that's crazy. And it's very, very good. Like mixing the sounds and like low latency is key. And it sounds really great. So I want to play with this. I was going to say, you need to make like a mount on there for one of our TRS jacks, huh? So plug it in right into the side. I also want to play with Remy's. He made his own features to the original Pico midi project as well, where you can like save some of your mappings, which is super cool. And that just really shows how Circuit Python is so capable of these days. So a huge shout out to Remy for sharing. And of course Todd Bot too, for doing so many cool things as he's Python in the community. Should be Audio Bot. He kind of, yeah. Todd Audio Bot. And here's Todd's, because I just have to play it. Like I love the almond. I am a huge Remy bass fan. He's playing the almond. Like that is the most like historical like sample you could play is the flippin' almond. The almond brothers? Yeah man, the almond brothers right here. Yeah. So, should shout out to them both. I'm going to get a mount where he's like actually doing it too. Oh wow. So, huge shout out to everybody. All right. And that's the midi fighter. All right, we've got another one here. This is a mag tag case make. I'm okay with that. Phoenix posted up their make of the 3D printed case for the mag tag. That's that internet of things that you can just eat ink display from native fruit. And it says dirty. I'm guessing that's for the dishwasher. Yeah, I guess the dishwasher is dirty. Three dishes rather. But yeah, very cool. I'm glad the case works out. You can snap fit it. You can prop it up on your magnetic surface. It's all good. It says easy to print, fits together wonderfully. Guy mentions using the stand fit battery. I used the M3 standoffs instead. Very good, very good. Very nice. All right, got another one here. It's a bit of a kind of a tool thing. If you ever have a tripod adapter, I mean, rather if you ever have a camera and you want to use a mic stand, you can use this little adapter that I made a couple of years ago. So dad and Fintium on Thingiverse posted up their make. So this little 3D printed adapter takes the threading from a traditional microphone stand and allows you to put a quarter 20 screw that's the standard thread size for a camera. Looks like dad and Fintium here. Kind of made it so it just kind of press fits into their Logitech 270. So that's really cool to see. Yeah, it's really cool. I like using my mic stand too to be a tripod. Which is, I think it's five and a quarter? Yeah, I think it's five and a quarter, five eighths, something like that. Here's our make of it. I forget what I designed it in, but it was pretty much to do an overhead camera. It's just like this little thing. You would put a D-ring through it, but you can remix it to go right into it because I think the Logitech webcam he had didn't have a tripod screw. So he made it work so you don't need one. So that's cool to see folks making their own remixes. All right, and then second to the last one. This is really cool. Really appreciate this one. We like doing a lot of 3D printed props and we tend to put electronics in them. But you don't always have to go the whole route and put electronics in it. So Kaylee89 on Thingiverse made the Halo Energy Sword and then just weathered the blades that look cool. So you don't need electronics and just snap fits together. It's all hollow and nice and lightweight. So you can swing it around probably. But yeah, it's cool. The blades, a couple of different parts you could print. I use the sculpting tool to create the handle. Yeah, that was great. So it's got no light, but the iridescent colors. So you get that cool look at it. Printed at 80% so scale down a little bit. And would you know, the printer that uses cruelty enter. Time and time again, I just keep seeing. That's what made us get one. It's like all the makes it we're seeing. Because then it's like, oh, all of our tolerance will work with everyone else. Yeah, yeah, that's another good point. All right, and the last one for this segment. I don't know what it was. There's a pie zero stand because they're very useful. So TK, T-Co-Pain, I think we're supposed to up there make for the pie zero stand. Very nice. And we'll still print a stand you can make. I like that sparkly feeling. I like this very moment too, it really pops. Very cool. And again, printed on the under. Is it like the default printer that you post to make? I mean, again, the quality speaks for itself. The usability too. So cool. That is this week's Community Makes. Thank you everybody for posting up their makes. Really appreciate folks sharing their stuff with us. All right, folks. If you have any other questions, comments, drop them down. We're gonna close up the show. We're on overtime now. Whoops. Yeah. We gotta go. But don't go anywhere tonight. We have a special show in Tel hosted by JP. John Park is hosting it tonight. Can't wait to show him Zoetrope stuff, Zoetrope. And yeah, the show in Tel, it's tonight. Right up to that. He's hosting it. Right after that is Asking Engineer Lamar Phil. Full hour of open source hardware news, top secret stuff. Is it IonMPI? Yes. Yeah, IonMPI. And new products, of course. Then John Parker will be doing a show on Thursday, every Thursday at 4 p.m. Eastern time. Deep dive to Scott. Every Friday, 2 p.m. Pacific, or 5 p.m. I was about to say electric. Eastern. Eastern. And I think it's already announced. I think FOMI Guy will be taking over, I think, in about a month or three weeks. Oh, I don't know if we're spoiling him. We need to make FOMI Guy special. I thought he already talked about it. All right. And then on Sundays is from the desk of Lady Aida, live streams, where she does the special segment, The Great Search with Dijiki. Yes. Yeah. Wrapping around to the start of the weekend. Yeah, Mondays, the Circuit Python meeting time. This is a great opportunity to tune in to the Circuit Python devs and community, find out what's going on every Monday at 2 p.m. Eastern time. Which FOMI Guy said, yes, it's already public know-eries and he hosted it last week or this week. Oh, I'm sorry. I gotta re-watch it. Cool. All right. Taking the reins. Yeah. What we like to hear. That's great. Expanding the network of our shows. That's great. And then Tuesday's very special product picks of the week. You have to tune in live to get that 50% off. So make sure. And just see that fantastic thumbnail. I've load that serial thumbnail. He was so proud of it too. He posted it on Facebook. I was like, yes. So shout out to JP. The face made it. His picks are always the best. This week he made his own Arduino on a breadboard. That's crazy. It's like 30 years later. Do you know how to do it? That's super cool. And then wraps around Wednesday's. It starts off with Wednesday's, at least three. I don't have a banner, but yesterday, I think you probably saw it, folks. Super cool interview with Pyramony and Lamar. Paul Lamar were on there chatting up. Lady. Aida. Lady. Aida. No, it's Aida. I think we did that mistake when we first started to. Yeah. In fact, it was like, no. Aida fruit. It's Aida fruit. You can say however you want. We're not, I keep saying zoe trove. It's zoe antrope. All right. Well, thank you, Deweyster, for your time. Thank you, everybody, for your time hanging out with us. This is what would do it. Hope you're inspired. Cause I am. I'm inspired to come on and see what everybody's doing. Good luck with all your maker endeavors. Until then, make sure to make a great day. See you later tonight. Bye, folks.
