 Hey, what's up, folks? So I'll go back to another 3D Hangouts. My name is Noeva Ruiz. I am a designer here at Adafruit. Joining me every week is my brother Pedro. Good morning, everybody. I'm Pedro. I was creative tech here at Adafruit. And every week, we're here to show three different projects, feature electronics from everyone from Adafruit. That's right. And everyone. Yep, share and show and share. That's right. This is where we combine 3D printing and DIY electronics to make inspirational projects. Hello, everybody, hanging out in the Discord chat room. If you'd like to join us during the show, you can drop in a message, question, gif, meme, gif, all on the live broadcast chat channel on the Adafruit Discord server. The link to that is at the top in our purple bar here, discord.gg slash Adafruit. We'll take a couple moments to welcome everybody. Hey, folks. Good morning, good morning. I got Rosyn, Squid.jpg, hanging out in the Discord. Andy Callaway, hello, good morning. Thanks for joining us. We have some fun things. This is episode 425. It's October. No, it's not. It's December 13th, 2023, almost at the end of the year. Pretty much. We have a nice and simple project this week. We have Pedro's prototyping, a new qualia project with a round display. We have a fun festive time-lapse Tuesday, and we have a single community make this week. I think we have a shop talk, maybe not, but we'll see. So we'll kick off the show with Adafruit.com slash free, all the freebies that are available. When you purchase more things at Adafruit, you will get some freebies. Starting off with our first tier for $99 or more, you'll get a free PCB coaster with the golden Adafruit logo, of course. That's that lovely aluminum thick coaster. For orders that are $149 or more, you'll get a free KB2040 dev board. That's that lovely dev board with the RP2040 chip and all the features that you know and love. If your order is $299 or more, you'll get free UPS Ground Shipping for continental US only, the KB2040, the PCB coaster, all that for the $199 mark. And if it's a whopping $299 or more, you'll get the free UPS Ground Shipping, the KB2040, the PCB coaster, and a Circuit Playground Express. All of these get automatically added to your cart. And on top of that, we have a 10% discount code for today only, and it is PyCase. PyCase, all lowercase, and all together, because that is celebrating this week's project. Another thing we want to note is holiday shipping. The deadlines are on a dedicated website, Adafruit.com, slash holiday. You can get all the different deadlines for domestic orders, international orders, and also some holidays where Adafruit does not ship. So check those out. There's also a blog post about it. Yeah, depending on your tier, we'll have a different date. So if you are trying to get some parts in before the holiday break, there's still a little bit of time. There it is today. And that's all my email is filled with last date order to get before Christmas. Yeah, yep. All right. So you also post the links to all of the new letters that we have, at AdafruitDaily.com. Check those out. Lots of tips and tricks. Now of our top 10, excuse me, I got a sneeze. Those are tight. OK, so that is the morning. We have some more folks hanging out in the Discord chat room. We have Cup of Coffee, DeVal, Dan Mitchell. Hello, welcome to the show. Good morning. All right, I think we're ready to talk about a Raspberry Pi 5. So the Raspberry Pi 5 is the latest addition to the Pi family. And I happen to have one here. I haven't really played with it yet. So this week, I got an opportunity to design a simple two-piece snap fit enclosure for it. I just got it set up. My goal with the 3D printed case was to accommodate the Raspberry Pi official active cooling fan. So you've seen cooling fans before for the Raspberry Pi 4 and lower, but this one has a built-in heat sink. It's got these lovely plastic spring screws, hardware. And you'll notice that the Pi 5 has dedicated mounting holes for their active cooling fan. So I found a model of the Pi 5 and the active cooling fan on GitHub. I can share a link to those. But I was able to get that into my CAD package, Fusion 360, and design around these things. And everything kind of fit for the most part. And we'll talk about some features here. So I wanted it to, of course, accommodate the active cooling fan, but also not really use any screws. So you have the same mounting holes, the four mounting holes, that are M25-sized. So I just wanted to make some built-in standoffs. So this is the bottom half of the case. And we have a series of vents or slots. They're actually M3-sized slots. So you can use these slots to mount components or mount this to something else. We have the ports. We have a little bit of an indentation here just to kind of accommodate for clearances so that the surface is closer to these ports. So you have the USB-C for power. You have the two mini, I think it is it micro or mini? I think maybe it's micro HDMI. And then you have a nice large opening here for the gigabit ethernet, the USB-3 ports, and the USB-2 ports. So the way it is, you kind of have to get it in here and just kind of get it to click into place. Sometimes it works at an angle a little bit better. Let's see if I can, there you go. So that clicks in there, you get a nice click and you can see that those little nubs will keep the pie from like shifting around in there. Caution be careful with the, what is it, the power button piece? Yeah, so there's a power button. I do have access to it. It could be a little bit bigger, I think, because you can't really kind of get into it. I like being able to poke it. Or, yeah, you might be right, like the tab that has the little push button in there. A tab could work. I just ran out of kind of clearance because I have a slot here for this year. So if you want to update the design, by all means, check it out. But I have a nice slot here for the SD card to come through. And then of course, by suggestion of Liz, she wanted a little hole here for the status LED. Yeah. And so that status LED will shine through nicely, no problem. So you got that, and that's kind of the bottom half of it. For the top half, it's always important to have some cutouts for the GPIO header. So it's that two by 20. It's the same. There are some snap fit nubs here and there's some corner things just kind of keep it registered so it doesn't slide out. But you got some strategically placed snap fit nubs here that will grab onto the inner nubs of the case of the bottom half. So we just line that up and you get a nice click there and then a click right there. So that covers it up. So you can see here, I have extra tall stacking headers right here in the GPIO. And that is so I can attach an extra accessory. So if you have like a pie TFT or a pyrimony board, this is actually Adafruit's pie barrette or barrette, I guess. And this allows you to attach an iSpy display with some extra add-ons like two user buttons. So you have two user buttons here and then you have a switch here. And then this is a temperature sensor. This is that lovely A-HT20 temperature sensor. And it just connects via STEMA QT. So this is a really nice accessory for your Raspberry Pi. It gives you that ability to add that iSpy display, couple buttons, a switch and of course STEMA QT with these two extra mounting holes you can have a series of boards. So I was able to just use an M25 hardware to attach it right on top, no soldering. It's all assembled. So I just literally plug and play and now I have an extra temperature sensor then I can line these up. And I really like that you can just press that down as far as you want. And now you have way more capabilities with your Raspberry Pi 5. And it makes the sensor a lot more accurate too since it's outside of the case, it's right by the fans. It's not gonna heat up, get cooled down. Yeah, it's nice. And you can mount it somewhere else I guess you could mount it back here if you wanted to. So these fans here, these grills here allow you to get airflow into the active cooling fan. This is the PCIe slot. So you'd have a ribbon cable sticking out there. And then these are the two camera ribbon connectors there. So you always have access to those. Some things you could add, you could add access to those additional ports. I think they're like kind of the STEMA QT style port. Oh, the UART port. The UART port, yeah. I think that's where the, no, the fan has its own like dedicated thing. I didn't expose those just cause I thought... No, you don't need to. Yeah, I didn't need to add them yet, but you folks could add holes to the bottom half they want. I imagine folks are gonna remix it to have whatever. Maybe a tripod screw would be a nice addition here somewhere you could add it here too if you wanted it. But yeah, it's just like a simple kind of general purpose case. That's kind of my goal. And the prints without any supports, of course, snap fits, print it in whatever color. It's just gonna keep it off the desk. So I made sure that the clearances for the various cables worked well with the ports. So this is the micro HDMI to full-size HDMI. This is like the official Raspberry Pi cable. And I did find in my first iterations that it wasn't quite fitting all the way. So I made sure that I had all the clearances for this chunky cable to fit through. And then of course you have USB-C that fits perfectly there too. So it has plenty of clearance for all your cables because you will be having to plug things in. These aren't really an issue. The USB ports, they just kind of are out there and exposed, so those are nice. But this was important to make sure that it was right. So that works well there with that indentation. And it's indented because in order to get the snap fit nubs to fit in there, I had to kind of spread this out a bit more. So the case had to be a little bit wider so that there's clearance for those snap fit nubs. All these little things that you have to accommodate for when you're designing around a case that you want to snap fit, you got to have those clearances and sometimes it's good to have these indentations like these ports here. So that's it in a nutshell. I don't have it powered on, but we do have demo code for the AHT20. That's what I had running in the video. It's just the demo code that just displays. It prints out in the terminal, the temperature reading. Yeah, there are some extra things you have to do with the new Bookworm operating system for the Raspberry Pi for running Python scripts. You have to set up your environment, but that's all documented in the Pi Foundations website. So check those out. I think we'll be doing some more Pi projects, but this is really the first time I've played with it. Yeah, so that is the case. It is up now on the Adafruit learning system, principles, I'll get it up on some other sites as well. So, I mean, that's pretty much it. I don't think we really need to run through the guide. Everything's out of stock, but hopefully to know. Hopefully tonight we'll have some more available for folks that are watching live on Ask an Engineer. That seems to be working out pretty well, but of course just to reiterate, you have two versions of the Pi, the four gig and the eight gigabyte RAM. Active Cooling Fan is good to have. And this, you definitely want to pick this up because I was trying to run it off. Just in case I didn't have something that it wanted. So it's like, okay, this is made by you guys. Yeah, because I have a high voltage, PD, what is it, a PD power supply, but because of that 5.1 volts, like I got an error on the Pi OS saying, you can't, this will run, but it won't run at full power. Like the processor will be like limited because it doesn't have that extra 0.1 volts or something. So I would pick up the power supply because like you might think you have a nice beefy power supply and it still won't run, which really shows how powerful this thing is. Of course an HDMI cable if you need it for your display. And then an eight gigabyte micro SD card is pretty good. Okay, I think this is the eight gigabyte one. I need to update that. This is the 16 gigabyte one. And then the stacking headers if you want to do accessories because that's nice to have for the CAD files. It's all STLs, a step file. And of course the Fusion 360 file, if you want like the full design history and timeline, all that's there. The build volume for 3D printing it is pretty low 90 millimeters by 66 by 20. That's pretty much any printer, even like the resin printers I think are that big. I haven't tested it in resin. I'm sure you can manage. Yeah, yep. That's pretty much it. Just a nice light case for folks. Of course there's plenty of other cases too. I've noticed that there are a handful of cases out there like on printables. Might as well add one to the mix. Yeah, some of them might not include the source file. So maybe it's good to kind of start off with this and then modify it to your needs. That's always a good thing. And that's what we do here. So that is this week's project. I gotta find a reason to turn it on. I think the thing I wanted was the Buddha tube, the little auto video player, YouTube video player that Jeff worked on, but I'm pretty sure it doesn't work on this. Yeah, this is all. Because this is still getting all the TFT displays that play nice with Bookworm. So it'll be a future project. I'll be back down. I think that a camera project. Oh, how funny. Timelapse project. Can you see that? That was hard. Oh, that's great. You got your... Oh, you're gonna stand for that. Does it work with the pie? Yep, and it comes out of the pie. Yeah, so the way Jeff's running on Sonoma, the macOS, they let you do various things. Do a thumbs up. I'm still not on Sonoma. So you get these like kind of interesting. What's the rocker one? I think it's like this. You need two of them. Do it like this. You're doing that. You need to do this. It's not working. Try to make like a laser light show go on. We have really went off the rails. And that's the point about the Simona thing. Like it just throws it off the rails. We have some questions. We got one from the masters. When you play in a restock, the basic lock and pin set. I'm not sure about that one. Oh, maybe. Yeah, I'm not sure. Yeah, maybe it's a player when quiet. That'd be a good question for the heads, for Mr. and Mrs. Lady Aida. They'd be able to check on that for you. That might be what the reason is. Yep, no ETA says Brent. Brent is in the chat. You can always sign up to get notified when they're back in stock. That's good. What amount of RAM should I get for the desktop Raspberry Pi five? Well, it depends what you want to do. If you're just doing web browsing, I suppose a four gigabyte would be fine. If you're doing some more intense things like maybe some AI projects, you'll probably want to get the eight gigabyte version. Yep. I think I put all the links in there. Oh, 3D hub, not 3D hubs. The GitHub of the 3D parts library. Yes. 4C, layer by layer playlist. All there for any questions on modifying the design. Yeah. Yep. And since there's step files, you can bring that into FreeCAD, Onshape, any of those solid works, even Tinkercad. Oh, yeah. Don't forget Tinkercad. Okay. For any other questions about products, pretty much just sign up to get notified when they're back in stock. It's hard to kind of pinpoint one product and find out exactly when it's going to be in stock. But if you are looking for Raspberry Pi, tune in tonight on Ask an Engineer, and you may be surprised to see if that... Yeah, it says it might be the risk of occurring the power capabilities. Okay. Yeah, if you're doing... And Kelly says the point one makes all the difference. Yeah, the volts, yeah, on the power supply. All right. Let's get into what are we prototyping? Yeah, let's do prototyping next. This week on what are we prototyping? We got the 2.1 inch round display. So we're going to do a little port of the video player for this. The theming for this smaller one is going to be in ornament. So it has the little thingy on here. I think you just put one of the regular ornament holder thingies in the back of your tree. They're cool. So it'll do the video playback. Doing the MPEG, no, yeah, M-JPEG format. So we'll be able to run that. I think Liz is going to scale it down and adjust the code. And instead of having the SD card play all the videos, I think we're just going to have it play right off the internal memory that it has. So of course, SnapSit case houses the qualia display. I'll plug this guy here. See that everything mounts inside there. We have the frame that is holding the qualia in place and that's just sandwiching in the actual display. Get out. Oh, it doesn't come off easy now because I had to do these little tabs so make sure that when you tap on it, it doesn't just push all the way through. Oh, right. I don't want to. Yeah, you leave it nice in there. Yeah, yeah. Yeah, you would have to take the board out and then you can flex the insert out. I suppose, yeah. I think what I'm going to do first is unscrew the qualia board, take that out and then I should be able to get it out of there at an angle but we'll just leave it in there for now. That's the way everything mounts. So it's just three pieces and then for the lid, we have little snaps on there. I'm going to add some end stops so that it doesn't unalign with the little boot button that we have on there. Probably going to have to use that a bunch to get all of your movie files in there. Yeah, so no soldering for this one. Yeah, no soldering. So it should be a similar way. It will fit, hopefully. Exactly, yeah. On the internal flash. So some of the design considerations was just making sure that the ribbon cable hat was not being flexed so much. So it did have to adjust like how far away the qualia board is from where it is positioned on the frame. I think I'm going to have to push a little bit more but it should be fine there. It's an interesting design challenge with these round displays. It's like, well, my board is a square. I'm going to have like your corners kind of get in the way, so. It's definitely easier than doing the 2.8 one because that one had such a weird shape. I think you said you actually took a picture and like drew it because of the way that it's all along. Oh, the four inch one? Oh, four inch, sorry, yeah. The four inch one is weird. So this one doesn't have that weird oblong shape. No, it does have it but because of the way that the touch screen is, it goes beyond it. So it's perfect circle for building your outlines for the case. Cool. I think Liz is going to do modification for this one to add the accelerometer on there. She can make a compass. Yep, yeah, she's going to be working on a compass. So it'll use a STEMA QT accelerometer, gyroscope. Yeah. And that'll be a fun one. So probably, there might be some clearance underneath the quality board or no. There is about five millimeters. Maybe you can live outside on the case. We're making the side decisions right now. Maybe you can, maybe some mounting holes, some standoffs on the back cover. Since I'm only using two here, you could piggyback off the other two, make another holder down over, I think underneath the chip here, there should be a nice amount of space down here. Yeah. Because otherwise then you got to like, increase, make it taller, which... Yeah. And you can't really shift the board because then the ribbon cable will kind of come at it weird. Yeah, that's one of the things you have to think about when you design this case. Like the offset, yeah, it has to be a little offset. So you can kind of see it here. It's not completely straight. Right, okay, so there's already an offset, all right. Yeah. Maybe we can mount it to the remaining mounting hole on the quality. I was going to say mount it onto the... Yeah, mounting it there is what we can do. And then maybe a cutout or something if it's too... If it's raised up too high, you can cut it out a little bit on the back cover. You can be on the outside and then forget what I used it on. I think one of the pie ones where you just put a cover on top. Right. A few little notches where you just cover it up. Yeah. Be on the outside. But yep, this is what we've got so far for this 2.1-inch touch screen, touch round touch display. So I'll have the film cover on here. Just wait until I film before I remove that. 2.1-inch round. But it'll be in Arduino. So you should be able to check out the code for that. I think there's, I think Jeff or Melissa is porting the GIF code to be able to be run on a circuit Python, but not at the moment. Yep. 40 by 40 display. It'll be interesting to see how videos translate to like a circle. So we'll probably pick like videos that are circular, like a Stargate or something, you know? Something that makes sense. A must, the Stargate. Stargate, something else, but... I know there's more. Oh, for... Since it'll be a ornament. Couple years back, remember Brandy made it like a, not really, like the clear sheet just had like Gavin in the back with like snowflakes. So that's what we're going to do. Put the kids on there. Have like just snowflakes falling to the loop. Yeah. Yeah. There'd just be a still with the loop of the... Snowflakes or something. Snowflakes falling down. Yeah. It's a good one. And then for the USB, I can just plug in and be routed into the back of the tree somewhere. Yep. Do you also have a non-touch display? I wonder if it's the same shape. Do you think it would fit? Don't know. Because it doesn't have the touch display, it is going to be smaller. Like the diameter is going to be smaller because it doesn't need the overlay on it. So there's like a lip here. Yeah. That's true. Yeah. Yeah, the lip is what's helping me out. Oh, man. Because it's making it the, you know, a rounded circle. That one's like, you got to accommodate for that little end piece there where the ribbon comes out of. Yeah. Because that's actually what you're clamping down onto. Yeah. You have like a hexagon thing going on here. Yeah. What is that? The way it's positioned on there. Yeah. Well, if folks want to, there is a data sheet. So I suppose you can take a look at that. I think I had to do that for the four inch. Like I brought it in and traced it out with like a spline tool. Yeah. So you can get a gradient. Yep. At least these come with data sheets because you can be challenging to like take photos. And I went in there and just tried with the circle tool and then adding the square to the bottom as close as I could. These are nice. Yeah. So data sheets for the wind in case you want to make a custom one with, you know, with either one because there's two of these now. I wonder if I can find one without, there's a price difference. The touch screen because, you know, getting access to the buttons, you know, it'll be a little tough if it is used as an ornament. You know, then you can just touch to go to the next thing, you know, was the whole idea. Yeah. We got a question from the masters again about like, is it Arduino or Raspberry Pi Pico? It is an Arduino project because there are libraries for it. Let's see if I can pull up the Where's the learn guide for our fireplace? Just type of fireplace. Second newest one. Yeah. So the code is on GitHub. Here's the code. It's commented. The videos have to be a certain format with a certain scale, but I guess you could, this is where you would initialize the display. So we're going to update this, obviously for the round display. Here's another init code to get it started, which you can find inside the main qualia board guide. Every display that we support, they're all listed and they all have their individual code for initializing each size. Yep. Yep, you said it. And just a note, the qualia S3 should now ship with the bootloader. So if you buy one today, I think you'll get a one where you have, you don't have to do that bootload install step. So that's going to help a lot of people out because the first couple of batches, the first run didn't have a bootloader yet. So you had to kind of call it with a web serial tool, but all that's documented in case you still want to set up the bootloader. Yeah. So we think we got everything documented for folks that are getting started. So just be sure to look at the learn guide whenever you buy a product and just run through it and actually read it. Because even me, I'm impatient and I sometimes over like things, but you can set it up here. This will run you through installing the board package for the qualia. You know, you do have to add a different, what do you call it? The board manager URL here to get the actual ESP32 boards and it'll show up in there. So you can compile to it properly. We have the rainbow product demo as well. Pedro, that's what you're running. Yeah, yeah. It's two, but if you're doing Arduino, you can do it here or the UF2. You just want to drag and drop. To verify that they're not broken. Right, just to kind of quickly test. I think your display is in the slack. I think Jeff got one that was like showing lines across and the Mars like, you might be busted. So be careful. All right. Cool. Tait has a question. So I'll data sheet the screen, outer glass at about one millimeter thick plus or minus 0.2. Do you take the max value before adding FDM tolerances? I always add 0.2 for the tolerance. Yeah, I would, for sure. Yeah. I didn't look at the data sheet. I took my calipers out. Oh, really? That's a good, yeah. And then just add 0.2. Yeah, cause there's always a little bit of a difference. Like they all kind of have a- When they're manufactured it, maybe it gets misaligned somehow or they can change their supplier themselves. Yeah, just add that 0.2. Use your calipers even with the, like some of the mounting holes, like for you to make it, I'm just in there measuring it. Yep. Cool. And then other tolerances, yeah, about 0.35, I think it is for the snaps so that a print on print, like snapping together that'll align perfectly with having a little bit of give so I can hold it. Yeah. I'm gonna be able to actually open it. So that helps. Yeah, I was just thinking about having, I know you added them before, you have like a tab, like you can get your nail in there. Yeah, cause you are gonna have to open it, yeah. Yeah. Oh yeah, I forgot. Cause I don't have end stops. I'll have to do a twist. Oh, you can twist and pull it out. But I need to add end stops so that the button for the, I'm gonna change this to a tab so it'll have a little- Oh, with a little riser? Yeah, a little button actuator. Yeah, those are not- You have to actuate the button and that kind of needs to be aligned. So yeah, I'll add a end stops to that. But for now, just go in there and twist it on. It's kind of cool. Yeah, that's a nice feature. All right, that is what is your prototyping, some more quality of projects in the works. I think this might be the last project of the year for us. I think one or two, yeah, that one or the compass, the year in review or the, you know, the round out of all the stuff for 2023, which, man, it's a pretty cool project this year. Pretty cool. Having trouble remembering them, but I remember filming them and they were super fun. Yeah, yeah, it's a good recap for us. So I want to do a quick shop talk before jumping into the community makes and the time lapse. If you have a 3D printer and you're looking to get a better bed, I definitely recommend getting the style of double-sided PEI sheets. I got a S1 Plus from Creolty. It's like the Ender 3 series. And it came with a bed that was like that build tack material. It is, it was so, like it sticks too well and it leaves blemishes on my prints. Even if you have it, like the nozzle far away. It's crazy how it sticks so good. It sticks too well. So I'm sure if you've seen a review on it, you probably know, like get rid of that bed and just luckily the bed is like magnetic already. So this is adaptable with it, but these are great. They're double-sided. One side is textured and the other side is smooth. So you can get different surface qualities on your print. They come in different sizes. Just type in, you know, I think the keyword is like PEI sheet, double-sided. Yeah, that's a great keyword. Oh, there's a lot of different manufacturers that slap their name on it. This one's from these folks, but I had one from like Comgro on our Ender 3 V2. And this was just a different, same kind of material, just a different name brand, but they're great. You can flex them open. They stick, but they're super easy to remove once it cools down. Once it cools down, it falls right off. It doesn't even stick after it cools down. It's really nice. I can't recommend these more enough. It's a game changer, like if you haven't tried these yet. Yeah, I printed this and then when it cooled down, I go back into the room and check. I'm like, where did my hand go? Fricking kids, steal my hand. It was on the floor. Why is it on the floor? What did it slide off? Oh, I mean, like we're saying, the once the heat stops, you know, the weight of it. The weight of it? Oh, that's what it falls around on. It's unbalanced. That's fun. I mean, it's because it has the, it's supposed to be the thing where it's put it on a wall. Okay. All right, well, that brings us into this week's time lapse. Oh, no, I still had some stuff on the PI bed. They have changed their names like three times. I have like three different versions of this same link to where that you have here. The name has changed on it like three times, but now it's double tree or two trees. Yeah. The only thing I don't like is, you know, once you get one, you're already gonna have this magnetic plate attached. So it'd be nice if there was an option to get it without this magnetic. That's right. Well, it's just there for, yeah. It's just there to like, in case your bed doesn't have it. Yeah. I do think it's fine. So it's sandwiched between the steel spring, which is flexible. It just works really well. And if you have an auto touch build, what is it, sensor? Auto leveling sensor, it should detect it, no problem. So yeah. And then of course, get the right size. Yeah, the 300, 310 by 310. They come in all sorts of different versions. So I think this is like a, kind of your Prusa i3 slash Ender cruelty. So just make sure you pick your right size. Brent's asking, do we need to replace the PEI sheets often? At some point, they stop sticking, no matter how much I clean it, or you can do the alcohol, I do the scrub with the, what are the metal buyer thing? And it just doesn't adhere. So I got deadlines, man. I ripped that thing off, put a new one in. Yeah, they're not that expensive. 20 bucks, the 36 bucks, depending on your bed. I'll leave the print on there. I'm like, bro. You're gonna get over a hundred hours of printing on them. I want to say. That's because we're printing like every single day. Yeah. So if you're printing once a month, it'll last you for years. Yeah. The one I got on my Ender 3 is still lasting. It's been like, I think a year and a half. And it's still good. And if that side loses stick, flip it over. Yeah, that's a good point too. Yeah, you do have that ability to just flip it over, start using that side. And once you need to use either one of those sides, then I'm just like, bro, this thing will be here, especially, you know, if you order on the right day, it'll be there the next days. It's like spend time cleaning a thing, stuff not working, just put a new one in. Yep. And I think for TPU, it gets, of course, TPU just tends to stick a little better than PLA, but it works fine on it. Yep. I tend to leave the bed a little hot, and then I remove it. It tends to come off better when you're... Must, it has to be like 50 C for me to remove the TPU without it just permanently bonding to it. Yeah. Yep. So TPU, by the way, is the flexible filament for folks. Yeah. That's like the thing. Okay. Any other questions? I think we're good. Yeah. I think we talked about last week, oh my God, the crazy prices at during the Black Friday for the printer. Yeah, that's why I got the printer. I got the S1 plug. It's like $300. Oh my gosh. It used to be 1500 bucks. Yeah, yep. It's a 300 by 300 by 300. Uh-huh. It's got all the direct drive for flexibles, dual access, Z, motors, super silent motors. So quiet. Oh my God. This is great. Touch screen. It has the filament run-out, too. Yeah, the filament run-out sensor. Yeah, it's all standard stuff now. Yeah, it's amazing, man. Yeah, so great time to... The VR3 broke on me. It was like an acrylic back plate that was holding the... Which I'll call it, the whole motor that does the extrusions. I'm like, are you kidding me? Yeah. Chuck that whole thing away. I'm getting it. For $300, they had a brand new one that used to be 1700 bucks. So it's like, dude, come on. Yeah. Okay. This week's time. Got to see what the bank community makes. Is this awesome? Grinch hand. Perfect for the holidays. We have a little Grinch tree. So this obviously... The theme for this was so perfect. The cool thing about this one is we're doing the color changing on this. So it changes twice, as you can see. This is a perfect model for that. You can see right underneath here where the color change happens. It's going from red to white and the green. I could have did this one a little bit more closer down to where the white ends here, but I kind of wanted to show it off so we could talk about it and see. Where you're doing all the color changing, especially with bamboos or whatever multi-material additions you can add to your printer. It's a good reminder that you could do some really good ones with just a single extruder. Just doing the color swap and then doing your arrangement of your model at a certain way where the color change is pretty flat. Because when you're actually using this, it's going to be like that. You can't really see where the change happens because you're focused on where the object that he's holding, you're not paying attention to where the color is changing. Sorry, so this guy in here because this is the ornament he should have been holding instead of that one. Oh, yeah. Probably will do for the video, but yeah. Something like that. Yeah, fantastic model. What's that? It's a really nice model. Yeah, I think it is a paid model, so. Let me see here, man, it is 3D. It's by 3D Geeks. Texture on it. Three bucks and some change. Now that we were saying before, this is meant to go on a wall or like a pegboard out there. This is like they're holding their keys. That's perfect. Yeah. Holding your keys. You have places to hold your ornament or your keys. Yeah, it's perfect. Dingling. This is right here. Sugary photos. So this is a multi-material. Yeah, yeah. So that's always the thing. I mean, it's funny that it was printed in 3D. However, if you want without a multicolor printer, yeah, you can do it, yeah. I mean, I'm glad we did it this way because it's a good reminder that you don't have to do all that. It comes in two versions, right? One where it's all one model, and then you can print each part separately if you want. I don't recall. I only remember. What does it say here? I don't know. That's good. It's good. I'm just saying. You can scale it up. Here's some scaling things. 3MF and STL. That's always good to have. 3MF will have all of your colors like all set up already. No supports. Low infill. Two to three shells. This is... All good notes. They're all good notes to follow. Actually, I think it's 8% because of right down here where the hand happens, you want to have enough infill to catch where it starts building the cylinder part of the base of the hand. I think it's like 8% hexagonal infill for this one. And just 0.2 millimeters for the resolution. There is a little bit of overhang on this side. You can kind of see. I see, yep. I'm drooping this. Well, clever to do the... For the time lapse, it looks really cool that it's just like one part. Yeah. And we just color swapping. Looks very seamless. Yeah. And there it kind of looks like he has another long sleeve on top. Yeah, under shirt. A long drawn. I wonder if the fuzzy skin feature in Kira would look cool with it. Yeah, probably. Yeah. Because all of this is supposed to be fuzzy. Yeah. I haven't thought about leaving the strings that are left over from the head parking for the time lapse. Yeah, yeah, yeah. The skin. The fuzzy. Yeah. Ability to... How do I... Make this full screen. There's an ability to add this extra texture to the surface of your part. It's called fuzzy skin. I think it's under the experimental tab in your slicer, but yeah, you can see here. He looks like this kind of fun fuzzy skin. So in the model, it doesn't look like that. It's nice and smooth, but the fuzzy skin thing adds this nice texture to any solid model. Yeah, it's like a jittery motion to the... Yeah, it's like a jittery motion. I've seen people print teddy bears and things with it and it comes out really nice. There you kind of see it better with the light catching on it. Yeah, yeah, yeah. That might be a good one for this one. Sure. Yeah, it's kind of like the Grinch texture almost, so. I mean, he kind of has that modeled in there already, but with that addition, it would... Yeah, make it really pop. Yeah. Okay, hopefully that doesn't fall on my pegboard. Definitely worth it. I saw another like a free one, but it didn't, the quality of it was not nearly as good as this one. Yeah. Yeah, this one looks really nice. Cool. Yeah. We have a metal door, so I was thinking maybe printing it and adding a magnet and the odenium. And then that way, like you just stick it on there without having to worry about like a M3 or a 3M hanger thing. I wonder if 3M makes like a nail or something to hook up in there. It's just like the M3 tape. Yeah, yeah, the command hooks. Command hook. Command nail. Command nail. Cool. Very cool model. Again, it's paid, but I knew that's gonna work. This door was cheaper when I got it. Maybe it was like the Black Friday deal or something. My thing fell. No. Yeah. Let me show what happened. It popped open. Luckily it snap fits, right? There we go. All good. Nothing broke. All right. Okay, I put it on correctly. I just had to stand up and put it on. I have a key, a peg holder, and that's where I keep like all my projects. Anywho, there's the part. Let me throw a link to the Colts 3D thing in all of our chat. It's fine. People can search on Amazon for the build plate because we're not tied to one or whatever. Oh, you already did one. That's good. Brent found it. Oh, no, Brent did it. Thank you, Brent. Yep, do you need to reply? Yeah, we already answered that. So there is, yeah. Whenever it stops ticking, model. Yep, it's like Facebook stopped working for links. That's fine. Okay, we have one community make this week. This one's from Kale. Kale says, they printed the heat set insert press. They said they printed in PLA, printed great. My other parts aren't here yet. The inserts, the extrusion, the T nuts, soldering iron, et cetera. But the parts feel solid. I think it'll work great. We'll update if things do not work out well. All right, well, let me know. It was like a follow-up. These are all the parts. They just need the hardware. Like we said, it's a little extrusion. Some ball bearings, string. All sorts of different remixes available. People tend to do the clamp remix where they'll add like a clamp thing for their soldering iron so they can remove it. So in their own weight things, but mainly the main clamp thing. Super cool to see folks continuing to add their own modifications to a very versatile rig for doing heat set inserts. Yeah, make your own. Cool, and that is this week's community makes. Thank you Kale for posting up their make. And hopefully we'll see their build when all the hardware comes. All right, before you end the show, don't forget we have a coupon code for anything in the age for a job that's physical using the coupon code pi case. Look at your 10% off. All the freebies are still available as well. And trying to pull up any other remaining tabs. Oh, there's a question. Yes, question, is it this Gorge? I'm requesting a heart-shaped pendant that will blink by sensing a person's heartbeat. That sounds like a, what is it called? We have a sensor that does heartbeats. Do you remember this? I've never used it, but I know we have a learn guide on it. Yeah, is it this one? Was it Colin who made? No, I think it's this one, isn't it? A pulse sensor. Yeah, yeah. No, I think he made a project with it, right? Where the whole room, the lights of the whole room would pulse into your heart. Yeah. You have a purse with a neopixel ring. And here's the pulse room. Pulse room. There you go. Yeah, this is an Arduino project. There's a library, an Adafruit library. There's the code, and it does the sound as well. For the heart-shaped pendant portion of that, you see and seed a little heart. We just soldered on the bare PCBs or the neopixels to it too. It should show up somewhere on there. I think this would probably be the better code, or maybe not, I'm not sure. Is it the Arduino, yeah, it's Arduino as well. Oh, now it's starting to look like the shape. Oh, yeah, code, yeah. Probably Colin, this is the one newer. Maybe. There's two pieces of code, apparently. You can get the link for you from that. Yeah. I would look at the learn guide, the various learn guides here for the sensor. Yeah. So this would be a good, like, remake for Python. Like, that'd be a good project. Yeah. Maybe there's like a heart. Hmm. It might be good to do, like, depending on the size, you could use the neon neopixel strips to form a shape of a heart if you want to get one. If you have a small one, I suppose you could use an LED noodle. Like one of these. Oh, yeah, yeah. And then like the snowflake one. Yeah, so there's all sorts of different ways to do it. So depending on what size, what application, you might want to change up, whether it's a regular LED or a neopixel. There's the fun part, figuring out how you want to shape it, what part you want to use. Yep. Code should be adaptable. Yeah. But we do have that sensor in stock, so check it out. Well, I just typed in heart and I found it through that. Yeah, always check the learn guide. There's so many. There's the entirety of Adafruit. There's so many guides in there. I think we've done everything like 10 times. Yeah. Well, this one's going to be redone in Python because it's a, this is a muscle sensor. Yeah, we have one where you like kind of flax in it. It'll trigger an on-off switch or something. All sorts of fun stuff. I still want to do the, I know Brent wanted to do one with the pump, sort of like pumps water in with Whippersnapper. I have a bunch of these moss poles. Oh yeah. So that would definitely help for that where I have like a bunch of tubes on like certain levels of the moss pole. So it pumps the water into there instead of me going there, watering from the top and having gravity, you know, pull all the way down, be sweet to have, you know, something that, like on a timer with Whippersnapper, use the pump to like a minute or something of pumping fluid or water in there. Yeah. You would just design the brackets for holding everything together. And exactly, yeah. Could be whatever. It could be a QT Pi ESP32 or whatever. So yeah, that's a good one. Let's put that on the base. Oh no, it's there, I have it. I think about it every single time I water the plants. Every few days I think about it. Yeah, that'd be a great kind of hero demo project for Whippersnapper, which is our dope code IoT software for folks that are in the know. I think Brent's probably like, oh yes. Yes. I've heard of mentioned it before and then when I started making the moss poles for all this and as the plants grew, I'm like, oh crap, I really need this pump. Right. I have all the pieces that I just need to put together. Yeah. Hope I'm not sharing any personal data here on my Whippersnapper. Oh, here's my Whippersnapper devices. Oh, Rufio. Let me see. How do you see Rufio? I mean, quickly look for a valve. Is it this one, the liquid? No, that's the level sensor. I could have sworn there was one in there. Brent, let us know. Because I forget just how many components. God, I know. Yeah. Oh, I'm just saying, that one though. What happened? You said that you can add one. Okay, cool. Well, I guess once it's added and we will have a good project to test it. Perfect for springtime. Yeah, I think a spring project makes a lot of sense. Yeah, I didn't see one in my quick search, but there's quite a few. There's a lot of level sensors, but we actually need a valve, like a pump, right? Plenty of pumps in the store. Yeah. Cool. And it doesn't need to measure it. Just have it go off for like a minute or two. A minute, yeah. You'll just have to keep track of the water. And then you can use a water sensor when it's low. Oh, yeah. That's two in one. You get the back valve and then the sensor to know when it's low on the base of the water. Yeah. Make a pump into a component. Yeah. Yeah, that's a good idea. I didn't think about the sensing the level for the water. Open source. We're coming up with these additions on the fly. Cool. All right. We're pretty much at the end of the show, folks. Thanks, everybody. I'm glad you're here to make sure all the links have been posted in there. I don't see anything I forgot. No, I mean, that looks good. People check out Whippersnapper. Don't forget, aio.atorefree.com. Sign up. You get two devices free, a couple feeds. Just enough to get you to get your palette wet. Oh, yeah, kind of projects already. Get some ideas. Mm-hmm. Cool. All right, folks. Tonight, we invite you to come on Show & Tell. Starting at 7.30 p.m. Eastern Time. It's Show & Tell. You can get the invite code by hanging out, excuse me, on the Discord server, the eight of the Discord server, about five to 10 minutes before the show starts. Come on and share your projects. And then at 8 p.m. Eastern Time is Ask an Engineer. Get a full hour of open-source hardware news, new products, Python news, all that and more. Perhaps some projects will be available that we talked about today. Some flavored pie projects. Anyway, so that's tonight. Tomorrow is JP's workshop. It starts at 4 p.m., right? 4 p.m. Eastern Time. I think Fome Guy will be doing the deep dive on Friday. Sundays is a desk of Lady Aida live streams on random evening hours. We have the Circuit Python weekly on Mondays. JP's product pick of the week on Tuesdays. And then we're right back around on Wednesdays with our show and then Show & Tell and Ask an Engineer. More coupon codes tonight as well. So hang out and there we go. And now play some more pie releases. Yeah, I hope so. Get these out to folks. All right, folks. I think next week we might take off just because the holiday is right for the year. There's so many projects, but I think the show is because the kids are out of school going crazy. Yeah, you wanna spend time with them. So I think next week we'll probably take off the week after is the 27th, so we'll be off as well. And maybe we'll be back on the 3rd of January, 2024 if not the following week. But yeah, that is what we got going on. Of course, we'll make blog posts and be in the chat rooms so that folks know for out. But I hope everyone has a good, safe, festive break. And we'll see you probably tonight. I'm Show & Tell, I think. I'll come on with this. Martin fell know that this is happening. So I'll prime people up for the pie releases for that night. Yeah, and I'll know if they're coming out or not. Cool, all right. Well, with all that said, hope everybody has a good time. We'll see you next time. Until then, remember to make a great day. Bye, folks.
