 Hey, what's up folks? Welcome back to another 3D Hangouts. My name is Noah Roance. I'm a designer here at Adafruit. Enjoyed me every week. Isn't my brother Pedro. Good morning everybody. I'm Pedro's creative tech here at Adafruit. Every week we're here to share 3D Printed Projects each in electronics from Adafruit. That's right. This is a show we combine 3D printing and DIY electronics to inspire you, the lovely viewers. Hello everybody hanging out in the Discord chat room. Welcome to the show. We're so happy to see everybody and tuning in wherever you might be, whether you're live or not. Hello. You can join us during the live show. If you want to do that, you can hit up the Discord server. The invite code for that URL is discord.gg-adafruit. And we'll take a moment to welcome everybody to the show who's live and tuning in because that's what we do. We'll give them some shoutouts. I'll pay some bills and then we'll get into this week's super cool project. Shoutouts and good morning everybody hanging out in all of the chat rooms. We are hanging out in the YouTube, on Twitch, on Facebook, live on LinkedIn. Periscope. LinkedIn Periscope. Tiktok. Good morning everybody hanging out. Cera Cartoon. Good morning. Over on the Discord we have Andy Cadaway, Susan. We got to Wester and over on the Twitch hanging out and Facebook. Hey Facebook is working again. How about that? Yeah we had to update our stream key. It has changed. It used to be persistent. And now it's resistant. Good morning Rank Homes hanging out in the Facebook chat. Good morning everybody hanging out. Thank you all for joining us every single morning. Yeah, April, Jan on the YouTube. Good morning Stuart Riggs. My eyesight has changed. Alright so go ahead and jump into some of the housekeeping. Oh, okay. I wanted to talk about us. Alright let's pay some bills real quick. If you spend more money without your feet you'll get some free stuff. So this week we have some new tiers. I think they're the same from last week but hey let's surround about them. For $99 and more you'll automatically get a free Promo Proto half size breadboard. For orders that are $149 and more we'll get the Stemic UT breakout board, randomly selected for order. If you have an account make sure you don't have the same one twice. For orders that are $200 or more you'll get the randomly selected Stemic UT board, the Promo Proto half size breadboard and free ground shipping from UPS for content until U.S. only. Check this out. You can get the details at Adafruit.com free. You don't have to add any codes or anything to get these because they get automatically added to your cart. The smarts of PHP or whatever. What a concept. But yeah there's still freebies going on while supplies last. We used to have another board but the supplies didn't last so we had to give them all up. We gave so many of them free. It was the Circuit Playground Express but that's whatever. But that is the update to free. Pretty much the same as last week. Alright. We're still promoting the Halloween Hackfest. We have an actual printed poster of it right there. It's not a superimposed graphic. It's real. It's a real poster. Thank you so much for Teddy. Is it the Teddy Pipes in? Yes. Teddy Pipes asked if we wanted one. If anyone would like one of those. It's a real poster. We could get it because I guess we're sponsoring it. But if you have a project you'd like to enter into the contest, all you got to do is post it up on hackadio. I have a link somewhere. Somewhere, somewhere. The link has to be somewhere. Where's Pedro? I'm looking to it. I know. It's somewhere here. Come on. Halloween. Come on. I'm live. Good. I just posted it. Good because that's where I'm going to grab it from. Hang on. Over to hackadio.com. There we go. Slash, contest, slash. Couple numbers. I love couple numbers. It means it's unique and hackery. So here is the page. The page just got the link. Oh, I have you. Here's the link. There's submissions. There's 25 submissions this week. The deadline for this contest is Friday, Thursday, October 28 this year at 11.59 Pacific time. Even if you're not, definitely check out the submissions for some inspiration on some cool Halloween projects. Check out this book. Wow. This is a new one I haven't seen. It's a cool book. Oh, is this from Stewart? Stewart's? It is Stewart's. Excellent work, Stewart. Very, very cool. Got a lot of cool fun things here. Wow. That's intense. All right. Wiring diagram. But the effect though is super cool. But what's really cool is Stewart knows what's the details. If you actually use Adafruit stuff, you'll get double the prize money. So if I was a judge, I'd vote for Stewart. But it's a very cool one. There's a video too on his Twitter. So check it out. Very, very cool work, Stewart. It's very spooky and great use of all the different things. But you got a 3D printing, Mod Podge, laser cutting, DIY electronics, circa Python, all that stuff. So check it out. Very spooky, but very tech cool. Good blend of all the things. But that is the Halloween Hackfest update. So check it out. We got a banner. All right. Jobs Wanted. You can go to Jobs.Adafruit.com to see all the latest DIY style projects. If you're looking for a new gig or if you're an employer looking to get a maker with some skills, you can find them on Jobs.Adafruit.com. One of the ones that was highlighted last week was a full time WordPress Google for Adafruit. Yes. So if you find yourself savvy with WordPress, check out the Adafruit job listing. There's some new ones here too. Enrollment Director from Blue Stamp Engineering. Oshawa is hiring a community coordinator. It's a contract position. Yeah, but check them out. The Jobs.Adafruit.com. CircuPython meetings normally happen on Mondays. This week there was a holiday on Monday. So we did it on Tuesday. So shout out to all the core devs. This is a great way for all the community to tune in and hear what's happening in the latest CircuPython stuff. Recently reached a milestone for the Python on microcontrollers newsletter. 9,000 folks. This is a great way to get your Python related projects or products featured in front of all those lovely folks. So you can head up and Barela on Twitter or email. What is it? Support.Adafruit.com. I think it's cp. cp.Adafruit.com. Yeah, I'll figure it out. But you could also post it up on Discord and tag and Barela. She spearheaded the newsletter. All right. I think that's it. That's all the housekeeping newsletters. That's pretty much the one. We also have other newsletters right at the new newsletter. And the daily newsletter. But we're really highlighting the Python on microcontrollers because it's like 9,000 folks. It's like the highest subscribed newsletter out of all, I don't know, 10 or so, 12 newsletters. It's definitely the one that is the most worked on with many hands in the pot for this one to make sure you get an excellent weekly newsletter. In the pot. Yeah. All right. Let's get back over to. I need some, I need a pot of chicken noodle. Yes. Do I sound different? Additional shout outs to a couple of people joined in the fun here at Abrazan. We've got Yanni hanging out. Everybody's tweeting about the Captain Kirk going into the space on Blue Origin. Yeah. I'm just now floating up. Please post in the comments if you're watching it live in another channel too. I want to see what happens. Oh, it's happening right now. Yeah. Oh, that's brilliant. I did not know. All right. Let's go ahead and jump into this week's very simple bit. No, I wanted to talk about the project. What do we got here? We got some cool comments. The book is reminiscent of the book from The Ash vs. Evil Dead. Huh. I haven't actually seen that movie. Do you recommend it? I'll watch it. Since it's Halloween. Store. Hey, Store. Great work. Glad you're tuning in live. Oh, he wants the blaster gun. Yes. Yeah, we'll tell you about the blaster gun. It's due. It's just a blaster gun. Yeah, he did. The green one. Okay. Well, thanks, folks, for any more comments. I guess it already happened. Yanni's saying that he has already become an astronaut. Wow, that's crazy for an actor to become an astronaut. He beat Tom Cruise, huh? Tom, you are just second place. All right, let's go ahead and jump to this week's super cool project. I want to talk to the audience more. I'm going to go wear these guys. So a couple of weeks ago, you released the awesome three-printed arms and the, what is it, the frames for these glasses. These are the LED matrix glasses. How freaking cool are these? We have the new pixel ring around and a matrix that is big enough to have some scrolling text on there. Yes, yes. Yeah, so if you go to learn.84.com, we got a whole new learn guide on everything you need to know about the LED glasses and the driver board. So it's kind of a two-in-one thing. Did we show off last week the updated frame? I don't believe so. Well, let's take a look at some of the updates. And we just got our hands on the LED driver board. It's a little bit thinner than a feather, but has a bunch of goodies on there like a PDM mic, an Xcelerometer on there. You have the ability to hook up a LiPo battery by getting some traces on here. But we recommend using a USB battery. It's super easy to do. And it's powered by the NRF 52840 on here. And it can do some wireless Bluetooth transfers. Yeah, did you say the onboard sensors? I think I got them all PDM. Yeah, the PDM microphone, you do audio projects, and the Xcelerometer, or LIS3DH, or charging circuit, and tons of libraries for the LIS3DH, built-in slide switch. It even has a NeoPixel, like one right here, a little very tiny one. A little software button and your reset. Yes, so it's going to work with CircuitPython and Arduino. It's got the UF2 bootloader. So when you double-tap reset, you can drag and drop UF2 files, whether it's CircuitPython or some pre-compiled code. You can quickly swap out the code without having to worry about installing all the CircuitPython libraries, which I'm really happy about. So we have some really cool demos to share. This is a fresh one that I just got. So we have two sets right now. This is the Fire Code from Phil B. Pater Dragon. I just somewhat love the dragon look. But yeah, these are very, very cool fire effects. And I just drag and drop the UF2 from the Learn Guide, and it just loaded up nicely there. So the 3D printed frame has been updated. So it can fit now, not just the feather, but the BLE board. So the BLE board has M2 size slots, and they are slotted. So if you want to use something else to attach it to something else, you can do that. You don't have to use screws. You do not have to use screws, rather. And I'm just using hex nuts here to secure those screws. But yeah, they have enough clearance, just enough clearance to not short anything out. So that's really nice. Nice, tight fitting. It's pretty close to the feather shape and feather like the width of it. But it's slimmer because it doesn't have those pins break out. So you'll notice that there is some pins here. There are some pins, but those are for reset clock and data for the NRF if you want to do some debugging or something. But normally what we think Lamar wants folks to do is to use the STEMMQT connector so that you can daisy chain different sensors to it. But like I said, PDM mic can do the audio projects, and the accelerometer is going to do the motion-based things. I think I hit the reset button on accident. Let me hit it reset again. There you go. So yeah, this is all available to download right now on the Learn Guide. So let me put these on. I added some rubber bands in the back here just because it keeps it on my head a little bit better. But one of the things I noticed, like if you're going to wear this for a while, maybe you're like performing or something, like you probably want to add some pads here to make it even more comfortable. I would suggest some sugru and put it up into the shape of the bridge of your nose and that should hold on pretty good. Okay. These screws right here are 16 millimeter. You can get away with 14 millimeter, but I don't have those, but they're M25 here for the hinge. And yeah, and then M25 hex nuts here. But yeah, that's the way I designed it there. And then M3 holes are in here. There's three holes to choose from, but you want to choose the middle one there. And that is... Do I keep hitting reset? No, I think you're probably touching the circuits, like bridging something. I hope not. I think maybe the battery wouldn't be first. Anyway, yeah, that's the hinges. It's really, really simple assembly. You can check out the CAD animation if you want to get a breakdown on how it's assembled. But yeah, M25 for this, M3 for this, and M2 for that. I apologize that you have three different sizes of screws, but that's just the way it is. But yeah, you can totally see through them because of the slits here. It allows you to see very nicely. So I will swear them now. I think that's the coolest thing about this. You can actually see through them. You can fit them over your existing glasses. And if you don't want to 3D print the frames themselves, we actually have a couple of screw mounts in here that can be used for zip ties. So you can attach those to your existing frames. And even the costume prop glasses, like the oversized ones, you can attach those as well and fit those over your existing glasses. So a lot of options for wearing these. And yes, responding to Timmy on the YouTube, we have two Bluetooth apps that you can use. We've had these for many years. You can do more than just send text on them. You can do the color on them. You can change the program on there. So you have options for both iOS and Android. So definitely go pick those up. And we will show the demo for that in a little bit. Yeah, that's super cool. Because obviously you want to be able to control these with your phone. Yeah, we really wanted to highlight that in the video at the first. Yeah, check out the video. There is a lot of info packed commentary on there. You can check out. Yeah, so let's quickly scroll through the learning guide. You've got some really fun copy. Always have awesome stories and copy with all the products. But yeah, the LED glasses panel sold separately because you can power it by other boards like a feather or a QT Pi or a P2040. So you can do that. But this is the driver board is really what it's for. Yep, yep, yep. So all the different features and stuff on the board are laid out here. So if you want to get more details on that, you can just scroll through it and take a look at those bullet points. For the pinouts, if you are writing some programs for it, you'll want to know which pins to call for like the switch for the PDM mic. And they're all broken out here in our pretty pins PDF diagram that you can download. And this just walks you through all the little bits there. You got your JST connector and your USB-C type connector for power and programming. Static T connector for daisy-chaining I2C peripherals or sensors. You got that user button switch. Here's the pinout and circuit Python or an Arduino. Excuse me. And then these are the LEDs for the status indicator and the NeoPixel, which is also a status indicator accelerometer microphone because of the library you can talk to them by saying like board.excelerometer, board.microphone, clock and data. So that's how you can play with it. Program to it. And the arrangement of the LEDs, you have two 24 LED rings and then a grid of 16 by 5. That's like the text rolling. And then your STEMIQT on either side here. So if you wanted to add another thing here, you can add another STEMIQT or a STEMIQT like breakout if you want to do some sort of temperature sensing or something else. All right. And then the circuit Python page. Here's how you can download circuit Python and flash the firmware for it. Just use the reset button to get in the bootloader mode and drag and drop it. And you can install the latest version of circuit Python. We've got a bunch of other pages here that are mirrored in from all the circuit Python goodness. So like which editor we like to use and talking to the Ripple. If you've never played with circuit Python, this is going to walk you through all the things because they're kind of mirrored in from all the other circuit Python pages. And then this particular one, the circuit Python eye lights starter projects. These are all the projects that are currently here. These are going to get updated, I'm sure. There's one that does the accelerometer, the tap and look. So you can like tilt your head down and you can change the color of the LED rings. The Google the eyes is a cool one. We demo that in the video as well where you can shake your head left and right. And it will kind of make this little half of a ring like kind of rotate around the ring. Which is really fun. And then there's motion reactive lights demo. This is like an audio spectrum visualizer. Very, very cool. I really like this one. It looks a lot like the code that was in the LED matrix, the 13 by nine little QT one that we did. It's actually the same code that was but it was ported out for that one. So now you can kind of see this one. Excuse me. And then there's the fire code which I'm wearing right now. This one's also done in circuit Python. And those are the ones right now for the Bluetooth stuff. However, right now we currently only have it in Arduino. So if you scroll down to the Arduino section, go down to Bluetooth message scroller. And then here it's going to show you how to connect to it via the Bluetooth app. That's a free download for iOS or Android. And then there's where you want to tap on it. You could use the UART module to change up the text and the controller and the color picker module to change up the colors. So there's the UF2 download. If you don't want to install Arduino and get all your board profiles and libraries installed, you can just download the UF2 file and drag and drop it to here. So that's what I'm going to do now. So let's go ahead and take a look at how we do that. I'm going to go ahead and queue up some stuff here. So let's go over here while I arrange my windows and stuff. See if I can get all my right folders and stuff. All right, I think I'm ready to try it out. So I'm going to plug in the glasses through USB. I'm going to the bootloader mode. So let's go ahead and do the overhead. So in the overhead, I'm just going to go ahead and double tap, reset. So one, two, you get that green LED that lets me know I'm in the UF2 bootloader mode. Your LEDs are going to stop if they're running. That's fine. That's how it is. And then over on our desktop, you'll see that I have a new glasses boot USB drive. It's a simulated USB drive. So I'm going to drag and drop that UF2 file. It's named iLightBlueFruitScroll.UF2. I'm just going to drag that and then I'm going to drop it into the USB thing. Cancel. Sorry, I did it wrong. It's dragging and dropping so hard. So it'll start copying over. You can see that there. Over on the overhead, you can see, if had a frame, that there was a little loady thing. Now it's loaded by default. It's like 1% brightness. So I'm going to go ahead and fix that. So let's go ahead and get our somebody's app. I guess mine. Open up Blue Fruit Connect. It should show up on your device. Let me turn down the brightness. If you're demoing fun stuff, just turn your brightness down. LED glasses driver. That's the name of it. Let's go ahead and connect to it. The LEDs normally show that you're connected. Then you can go to the controller color picker. And then you can send it some sweet colors. Here it is super bright. By default, the text says, what does it say? Like download the Blue Fruit app, I think. Put it on your face. It probably won't just too short of cable. But yeah, that looks way better at a distance. It says connect, app, run, Blue Fruit. Run Blue Fruit Connect. Which I did post all of the links for Android and iOS. All of the chats, you can check those out. Then over here I can show you UART. In UART, there's a little text box. This is white because that's where the date is going to go. Here's what I'm going to update. I'll type in Pedro, Ruiz. Then you hit send. When you hit send, updates there. Then it even gives you a little readout here of what you just sent. Then you can go back over to controller, color picker. Just a color, maybe just some red or some nice, some green. It's pretty instant. Some blues, more greens. Let's do some purples. That's more purple. That's even more of a purple. Not more of a blue, whatever. Then you can change the brightness by using the slider here. That's good if you're in a super dark setting and you want to get a camera or something to get a good picture of it. Really solid. In addition to this, you also have the iOS app for your watch. You can actually select through a couple of the swatches on there. If you're on stage performing or something like that, you can have very quick access to that. I don't think I installed it here. Yep, I do have it. Take a look at what the interface looks like. You get pallets, which is kind of nice. I don't think you can do the UART stuff though because it's like the watch. It strips away some of the things. Maybe for the newer watch model, you can give the devs to... They have a keyboard now on there. A little tiny keyboard on your watch. I don't know. The watch is kind of... not the Flenny key. That's why you can't do UART on here, right? I just don't like using the watch. It's just a remote control to your phone. I don't really like to use the watch. But it is there, which is really cool. Hey, you got a mobile device. Mobile device is a mobile device. Here we go. You could use an iPad if you wanted to, right? Or even your M1 computer should be able to run on there too. Oh, that's right. If you have one. Tested it. It works. Very cool. Very reflective. There's a quick demo of installing a UF2. I'm getting in the bootloader mode, dragging and dropping. That was very difficult to do. I almost dropped it in the wrong spot. What else can I say about it? What do you guys think about it? Tell me, what do you want to know? People say... What do glasses say? You blind them. They say, good work. That's nice. Yeah, good work, everybody. Lamar and Phil combine together, and then everybody on the circuit by the team Phil B doing a lot of the demos. Mostly just all of the demos. And then Kat E4 documenting. Making the pretty pins for the LED drivers. So definitely check out the guides. There's a ton of examples and work that went into fully documenting all of the capabilities of it. You can program it. Like you said, in Arduino and in CircuitPython. A couple more really good demos coming out. I wanted to highlight one. Which one? What channel is this? The Show and Tell channel on our Discord. Really cool. With the actual blinky eyes. Help me find it on my screen. Let's see. Is it in general? It is Show and Tell. Where's the topic? It's like one of the newest ones. Scroll it just a little bit. Oh, scroll all the way down. It should come up. There it is. Maybe that's the top one. No, it keeps going. After they had gotten it. I just want to see it real quick. These are some cool demos that we don't have right now. But they're cool that folks are coming up with their own. Scroll down because there is a GitHub. To where all of these are located. Cool. With the blinky eyes. This really shows the matrix grid of it. There is quite enough to make these blinky eyes. If you keep scrolling down more, you can see the GitHub link for it. And even attaching it to the numchuck breakout board. So you can actually control where the eyes are looking. That's really cool. If you are doing some sort of fun. That part I did not see. Having the blink trigger. Super great. Amazing. This is squid.jpeg. Discord user squid.jpeg. Very cool. Excellent examples. Yeah, he posted it somewhere. I think it up somewhere. And mind your ass. Mind your, because of the microphone. And your bump bump right here. GitHub. Shifty eyes. There you go. Thank you, Squid. Look at this one. Let's drop this link in the... You can find it yourself too. Right. But I'm putting in the... The Discord live broadcast channel here. Shifty eyes. Very cool. And it's an Arduino project. So you can install Arduino and use the... I know. Just make sure you get your board profiles installed. That's all documented here in the Arduino setup of the learn guide. You'll need to do things. How many things? This many. Oh, for a second. I don't have my Arduino setup. I'm sorry. I'm a terrible person. But, UF2s are great. You can drag and drop them. Because even that alone is difficult. Yes. But yeah, here is how to set up your stuff. Your Arduino profile. It's not difficult. It's just you got to do it, right? And then there's another page called Arduino Board Testing. Cool. This tells you what you want to do. Okay. I'm going to have to do this later. Because I want to install it. The demo is very cool. I know, right? I don't think we have any of the breakouts. But I'll definitely have to put some on order. What do you mean? What breakouts? The num chuck. You sure? All right. Let's just a quick look at the learn guide. My contribution. It's down in the downloads. I have these 3D models of the PCB. So if you want to design some unique attachments or closures or whatever, you can use these 3D models. They're in different open formats such as 3MF, STL, STEP, and Fusion 360. They are all populated too. So you can get the LEDs or the components. The connectors, they're all there. And if you just want to laser cut something, you can use these schematics here. And get what do you look different? I guess it's just the screenshot. Because I know the holes are not actually that. But that's just the way it looks like in EagleCAD. But yeah, there you go. You can always use Lamar's schematics and PCB files to make a new file because they're open. Very, very fun. Yeah, there's the links to the Github, links, 3D models on Github for the panel and the driver. They're two separate models, two separate folders. So that's why I linked them out that way. The panel is just the glasses and then the Bluetooth driver board is right here. It's called the LED driver. And then you can have data sheets for the LED driver. That's the IS31FL3741, all the data sheets and everything is here. So it's really cool that everything about all the things are here. You even get the exact NR52840 module PDF data sheet. It's called the RayTac MBDT50Q So you get all the details for making a breakout using any of these components. So that's really cool. You get some footprints too. And that's the learn guide in a nutshell. I think there's more demo code getting added. But yeah, it's nice that you have a bunch of different options for dragging and dropping or walk you through installing the libraries and stuff because yeah, sometimes it's a little bit. And then you get the additional links to some of the other components you might need like the Stemma cables and the USB battery pack that we're using. I'm going to download the music reactive one. I want to download this one. Get that one set up here. So let me do it again. Where I do some live dragging and dropping. Tap reset. There's glasses boot. I need to go to my downloads folder. There it is. I'll just do it this way. There it goes. Put that copy. Hello! Hi! He's like a little different. One, one, one. They look like the brightness has been lowered or something. Like instead of this being white, it's not purple. That's cool. Hey, what's up folks? PDMike. Right there. So yeah, these are really cool audio ones because they're audio reactive, right? The googly eyes are cool too because you can tilt your head and move around. So that's cool. Super cool. Can't wait to put these on a pumpkin or something with that fire code. Yeah, I really like the fire code one actually. I'm going to switch it back. And then there's another one that we didn't demo to. Tap to change colors is always super cool. Yeah, that's the wrong spot. Synthwave says Yanni and it's more banter. And you can't do Callaway saying that with those glasses you could make a spectacle of yourself. Yeah. Lots of spec puns going on. Yeah, super cool for Halloween. There we go. Fire code. Yeah, I'm going to leave it on fire good. I think that's the coolest right now for the season. Especially our background with the pumpkins. I brought out the the tombstone with the Halloween eye. That's fun. That's cool. So yeah, that's this week's kind of project. The frames have been out for a second but we wanted to make a dedicated video for the LED driver and the LED panel. So you can check that out. It's a good video that shows those three demos. But yeah, more demos to come and shout out to everybody who's written their own demos. It's really, really cool to see on the discord there. That's going to be one of those where the projects will continue to be made well into the next year. And again, cat files for them. They're all available to download on the github. Learn guide. And there's just a dedicated guide for just the LED frames. The glasses frames. You can check that out. And then here's just the board itself that one was added last week. But it's still there so you can check it out. And a reminder that if the LED boards are not in stock you can use something like a cutie pie as what you were actually first showing it off as. So that does work as well. You might have to solder. I think it's only the RP2040 that has the stem out. But do you show it? Wire it up with a feather? Like a normal one? No. Last week's project is kind of like that because it's pretty much the same LED driver. Different LED arrangement. But you could totally do that project. The RP2040 doesn't have a built-in PMI but the feather sense does. And that's kind of how we wired it. Just zero clock, zero data, but you can see here the two photos of the feather and the the LED board. It's like almost the same size. But not quite because those pins, those header pins are missing. Alright so cool. You can sign up so you can get notified when more come back in stock. I didn't say that they were building a couple more. So they should be back back in your cart in a little bit. Cool. Maybe later in the day. Shout out to Team for releasing the Learn Guide and doing all the cool demo code and stuff. Alright cool. Let's go ahead and jump into this week's What are we privatizing? Yeah. We don't really have much updates. We could show off the Raygun I guess. Yeah. This is probably what we need to really start documenting Philby. This is a collab project with Philby so it's a fun 3D printed prop from Star Trek animated series. The slaver weapon. So you have a little trigger here. You have the speaker. You see the M4 with a PAM. Maybe three or two amplifier. And the little mini overspeakle here. So a lot of wires going on here but that's because there's a lot of connectors. At some point we're going to have some features here where you can change up the sound effects using this little slide potentiometer. It's really neat. We've got some magnets going on there so you can put this back on there. And there's a little speaker hole in there. It adds like bass to it. Yeah. Acoustics. Fun, huh? A little built-in slide switch. I do a little layer-by-layer on how to do these built-in holders for your projects. Very cool. And Paige is going to show off some different filaments that we've been playing with. Yeah, so Philby had a request on some shiny filament. So we are testing out this really simple one from, oh I forgot the name of it. I'll post a link in the comments though. This is a really nice shiny one. It looks like multiple parts. You can definitely tell the difference between the green that you were using before and this shiny PLA. Yeah, it looks more futuristic, more on par with what they think the show wanted. Yeah. So you definitely get a lot of very nice shiny highlights on here. And I think he's trying to avoid having to do any post-processing on it. So yeah, this is a really good way to go. The only thing that is not cool on it is the strength of the little snap fit parts. I did try a couple of different settings and like print it slower, printing it hotter. The infill doesn't matter just because of how few parameters there are for the little snap fit parts. But it just kept breaking. So unfortunately the only part that will be in the regular green will be the pommel. And as you can see here this is the part that we're talking about that kept breaking off. You even tried increasing the thickness of it and it's just the film. Whatever additives that they're adding for the shininess is making these little clippy parts. Yeah, brutal and break right off. No matter what settings I try setting it up to. But for the most part all the other parts don't have any of those snap fit parts. They're all like magnet stuff. So perfect for those. So that's the only bummer. And it's the only snap fit part really as you see here. The rest of the assembly is all screwed together. And there's magnets. Which makes it a lot easier to take apart than having to deal with designing and then getting your snaps to work. But yeah, this is a little bit of an over-engineering bit. You don't really need that there. But I thought it was fine since the way you're going to reprogram the board or recharge the battery is through the USB connector here. There's no room here for a cable and clearance and stuff. That's where all the engineering went into. Making sure that the assembly is not a pain in the neck. But yeah, these are some cool parts. Very fun. None of them really require any support. So I had to do a lot of little things like adding little drafted angles here to some of the geometry like this would have had a nasty overhang. I left it like that. And like a nice flat edge here for your buttons. Lots of little things here to make it assembly good easy and no supports. Yeah, very cool filament. I wish it was stronger with snaps. And the tolerance is because it's printed on two different printers, it's a little bit tighter. But it still works. It's just a little bit tighter. So I purposely make things a little bit more loose in my designs because I know that the ultimakers like to make things really, really tight. This is a really good filament. I mean, it's strong. It's just those snaps for whatever reason. So I am putting the link to the Amazon listing to that. Just with the caveat of that like we said before, the snap fit parts will come out kind of weak. Also you'll notice here I have a right-handed and a left-handed. I'm left-handed, sorry. But you can see here I made these right-hand. He's a right-hand man. And they do have a couple of other colors. This is from Nova maker shiny silk green puree. And if you haven't seen episode of Star Trek it's episode I have it in my downloads folder. Season one episode 14. I can't wait to see Phil B. I think he's posted it online in his cosplay so far. Yeah, we shared on the show the cat. Space cat. Yeah, very cool. So that's what we're prototyping. I'm going to start documenting this. Yeah, there's a lot of little things. Yes, we got that. We did not bring it out here. It is the Loki pruner. That one too. It goes into a document stage for that one. And then some cool projects with the wireless inductive LEDs. They want the gauntlet. The infinity gauntlet. Which I didn't know. I didn't know that it just came out. When did the movie come out? Like five years ago now or something like that? So I was super surprised that Lego gauntlet like back-ordered sold out. Super popular. So we're going to add some of the inductive wireless LEDs to that. Just design a quick little part. So the little LEDs will be held in place without being rattled around. And then John Park made a really cool guide on building like a stand for that. Got this really cool wood. So definitely check that out as well. And then after that, probably Christmas stuff. I see all of the retailers already bringing out all of their Christmas gear already. So that's what we're looking towards now. Funny. I'm replying to Stuart. Oh yeah, so KJ magnets. Yeah, you got the link there. A cool place to get all your magnets. Yeah, I forget the exact dimensions but in that link he'll tell you. These are the magnets that are used for the search of prop. They're inches, sorry. They're a quarter inch diameter and an eighth inch thick. It's really good. Philby already had these on hand. He's like, hi, this is perfect. I think we use these on past projects. Yeah, the magnets we stock in the store. They're really chunky and really big. Didn't work for the small prop. I wanted to get some smaller ones. But yeah, this is a great place to get magnets. They have all sorts of shapes, sizes, diameters. They got cubes. They have cubes. Discs. Yeah, I like the little they're like flat. They're great for like bracelets and stuff, remember? Yes, I do have those. Yeah, that's what I use for the LED the Bengal Cup. Something like that. Oh, I don't even know stars. Stars. You could sew them into things. That's great. Oh, and they have like little stars, stepped blocks. That's a new one. Never seen. Scratch my head and ah. Definitely be very aware of the size. I remember I ordered one. Got the wrong size in this giant arc segments. We're getting like thumb tags. Well, they have stickies. How cool. Oh, colors? Yeah, but anyway, I got this giant like the wrong size, totally wrong size came with a box of the warning on it. I was like, oh, jeez. That's fun. It's like danger. Your hand will get crushed. Just a YouTube video of like fake person getting his arms smashed. I saw that, yeah. Yeah, Sandy Kallaway saying Christmas, what happened? Did I miss Easter? I know. Christmas what? How all the Christmas stuff is coming out? Oh, it's just the way the big box stores are. They got to have their especially right now with all the shipping with the shipping being delayed and everything. So go ahead and get your Christmas just be happy that that's just going on. All right, let's go ahead and jump into this week's community that was what you're proud of. Magnets. How does it work? We're the Moscow super popular trending. All right, now we're on to Community Mates. I don't know where this came from like all of a sudden like everybody's talking about squid game. I don't know. I didn't know it was popular. I watched it maybe two weeks ago when it first came out and I was like, oh, this is neat. I had some time so I watched it and I was like, oh, this is cool. Well, you know what I mean? It's not cool that people are dying and stuff but it's got an interesting story, character development, blah, blah, blah. You don't have to watch it. Yeah, I've been watching all of the the spoilers and like the behind the scenes. I kind of built the sets. It's really, really cool visual effects for it. So that's the thing I've been watching. And of course the 3D printed mask which a polygonal mask like this has been around for quite a while. Yeah, in 2012, there's a really popular design that came out there on Thingiverse. And this is a really cool one printed or designed by I forget the name. We have it in the credits there. Yeah, I think the and what I really like is there's a little video on there on how we designed it inside of Blender. So you can see all the polygons, how he's connecting all of those. So check that out in the download. I'll post the link when I'm done modeling this mask. Yeah, Hab Yen put together a little... Hab Yen. Hab Yen, put a little video on how they put it together and they modeled it in Blender and what I like about this version because there's actually quite a few versions available on Thingiverse. This one has like a nice slot on the edge of the mask for rubber bands and a strap or something if you want to do that. But yeah, the thing files here, you can get a Blender file if you want to like get the original source and then the STLs are right there. And the popular one on Thingiverse, let's see do I have it. This one here, this is the main one that I've been seeing everybody. It's on the home page of Thingiverse. The only difference I can see is the side of the mask has a hole instead of like a slot so I kind of like the other version better. But yeah, shout out to all the folks who are modeling up their own version of the frontman mask. Yeah. But this is the one we downloaded. Shout out to Pedro for picking the lesser known downloaded one. You didn't even know this is a guy. Well, I saw it come up in the my RSS and that's where I find all of the like as soon as it's posted is it's when I start like I have like a whole giant spreadsheet of all of the interesting things that I see posted like in real time on all of the socials. And if you're wondering why I always post Thingiverse stuff it's because they're the only ones who have an RSS. I can't go to multiple websites and like go through there. I have one giant RSS feed as all of my new track and drop is actually kind of hard. I don't have time for that. They should get someone to convert their feed into an RSS. Right, we get it. So what we're going to do right now is we're going to walk through a little bit of a little tutorial on three at a time. One of the things that you wanted to know was how I set this up because a lot of the printing you just hand it off to me and I go figure it out and they're going to fix it and do all of the maintenance and figuring out how to get the most optimized way to slice that with supports on there and you know time we have to do this really quick. Let me do it. Alright, I'm going to go ahead and get the STL from Thingiverse. It comes in like this. So what Pager found out is to rotate it so I'm going to rotate it upside down. And one of the things I keep seeing everybody do is printing it upside down. In the air, which I've mentioned so many times here, I feel like a broken record I usually sink the model down into the bed. In this case I sunk it down about negative four millimeters. I got a tip real quick. Let me do a tip. You can use your hotkeys R and T to switch between rotate and you know move. So I'm just going to move this down. If you hover over the tools it'll actually tell you to what the... Oh that's cool S for scale, R for rotate. But you can see here under the Z box I'm just going to erase that and clear it out to make it say negative four millimeters that's what Pager said. I just have a nice even number for that. And another tip too if you look underneath you can see the blue is visualizing how much of that model is being sunk into the bed and what you want is a nice flat even little platform The more surface area you have folks the better adhesion you're going to get to your thing. So that in terms of like you know placing it on your bed that's the optimal way to place it down in your bed. Sink it down by four millimeters or so and check how much surface area you're getting that's touching the bed. I keep looking at you're watching and nervous. No it's spam calls. Okay. I'm like oh no we don't have time. No. Alright so when it comes to actual slice settings you're going to want your layer height to be whatever you like. We have a point two and the main thing I want to change here is something called the support line width. Yes. That doesn't show up so I had to turn that on. So right here under the little icon here you can drop down the quality and then it's right here support line width. We actually want to reduce that from whatever it was. It was point three eight. So we brought it down to point two just so that it's thinner. Yes. Good catch. That'll make it super easy to remove. There's no point in having the support materials be the exact same width of your actual geometry. Alright. And then down here for the infill you want to change this to something like gyroid and how much did you use? I think I used like six. Yeah I used super low infill. Okay. It's still kind of strong right? Yeah yeah I mean because of the thinness of it there's not too much infill on this to begin with. Alright. Alright and then here's the part you want the supports I just had it generated for me. I tried placing it myself and it just it would not the weight of the custom supports work and Kira is not as good as something like Simplify 3D. So yeah just have the overhang to like 70. Have the support placement everywhere. Pattern to zigzag. Density four percent. That's pretty much it. Oh and the brim too I think you were talking about that. The brim I didn't have a brim on there about six to eight something like that just so it like has that extra adhesion on the bottom since you are going to have like a relatively you know small like surface area on the bed anyway. Okay you actually turned off support interface you didn't need that? No that like it has a tendency to like fuse to the rest of the geometry so it's like you don't really need it here. I usually use it when you have like a really big flat like overhang. So I don't really need for that. I'll show you where the overhang is on this chin here. I got another tip here. I was getting a really really slow preview when I sliced it so Pedro told me a really good tip here if you bring up your preferences for Kira one of the very first things inside of general if you look down to forced layer view compatibility it's like the second to the last layer before you scroll this one. Alright there I enable that. So turn that one and that will make your slice way faster. It was super slow like I didn't think we'd be able to do this. So let's go ahead and slice it. I think we do have to add some custom support though because of the chin or whatever. I think I did have to yeah. So we'll show you there. So once this is done preview, there we go. So this is That's not too bad. Right but there's nothing on the chin. There's nothing on the chin for some strange reason. So go back to prepare click on the model it's highlighted and then over here there's support which I got to remind people that is a plugin you have to add on. It's built in though. They're a little marketplace in there. It's just a you search for it type in custom words. Let me guess there's an update for the plugin. Probably yeah. There you go custom sports. Oh wait no it's already updated. But what's this for something else? You have time to scroll down for that some other one. No you're good. But in any manner use this thing and download custom supports under whatever plugins maybe. It's in there somewhere. You can see it's alphabetically so somewhere in here. There it is custom sports. Right there. Excellent. Yeah and it gives you a checkbox of what you have. So that's what we got. Should have to crash mirror for custom supports. So let's use it. Okay custom support. Click on the thing. Click on the thing. And then now we can just click on a piece here. It's just that top portion right there. There's your support. It kind of shoots through the head but that's fine. Now you can update you can have it like be tapered like a wider base and a smaller size for the top. And then you can also just scale the actual supports. Oh this is default right? Yeah. Oh you can go in the scale. Yeah you can go in there. But we don't need to do that right? Yeah. Okay. That's it. Alright let's slice it now. And then you should have that it's just that chin portion. I think some of the models I think it did see a remix where they just have it at an angle so you don't have that overhang on there. Yeah but let's see a lot of people printing it with more than Yeah way too much support. than you might need. But here's some tips here on how you can get away with printing it without so many supports there you can see. Yeah I was going to delete the ones that were in the eyes but they came out super clean so I would leave it on. It's problematic. But yeah that's how uh those are some tips. Hopefully they are helpful to you. Yay. Yeah. It would take 13 hours. And that's without a time lapse. Yeah I think the time I have it listed there I think it took like 24 hours and head moves, parks like chills for like a couple of seconds because of the long exposure or the long shutter short. No. Long shutter speed that I'm using on it. So these you can actually see through it you just hot glue them in there. Yeah just hot glue. You could have used super glue to make it look a little bit more cleaner but I was in a rush. I'm always afraid of haze. Oh yeah yeah so that's a the other thing too I broke one of the the grids so it was very easy to remove the hot glue so it would have been a nightmare with super glue. This here instead of just having a circle having a rectangular slit like here is really nice. Even though we're just using rubber band it'd be nice to have a nice comfortable ribbon and then a buckle of some sort. And then you added some of this insulation. So that's a weather sealant. The glue isn't the best it kind of sucks but the adhesive. I did the hot glue on the bottom I didn't add it to the top. That you could definitely do that. I have it on the nose bridge as well because it like goes into your nose. So just those two strips of weather sealant will make it very comfortable because otherwise it's like trying to get into your eyeballs. Yeah that hurts. Yeah I wish I wore this when I did that beat. Cause I was just sitting there taking the paint. And of course you can see through the grids. Yeah you totally can. I am beat. I can drum. That O20 is looking for Max Headroom Mask with integrated LED glasses. That is a really good idea. Switch. That's Susan. Yes Halloween all around please yes. My wife has Hocus Pocus running. On repeat. On repeat all year long. All year long. All month long. All year long. I don't know. Thanks for the people liking the haircut. Yeah. It was like two years since I cut my hair. Did you see the haircut Pedro? It's not even like done or anything. I didn't even style her anything. My wife was cutting it for she cut it twice during the lockdown. It got too long. It's like a pain in the butt to cut. She gave up. I just put in a ponytail. I had a band bun. I have snaps of me getting the tail removed post that later. Yeah. I can finally feel a breeze in the back. So much better. I cut my own hair. Yeah maybe I'll go at some point. Yeah thanks. And we actually look like brothers now. That's funny. I like how we're like wearing the same not the same but the Epcot shirts. By the way this goes really well. The shirt goes really well. Yeah it does. It's in front of white. I wish they made a black one too. Just invert the colors. Like a blue one or something. Alright I think that is going to do for this episode. Oh yeah it is time for lunch. I am starving. We've got to worship this part. Later tonight we're going to be hosting the Adafruit show and tell. So please come on and show off the cool stuff you guys are working on. Yeah. It could be electronics, PCBs, 3D printing, designs in the process or even your child's art project. Always cool to see. Definitely love seeing updates on all the projects you guys are working on. So definitely stop by and show that off. Okay and then shortly after we'll be asking an engineer at 8pm each time every Wednesday at 8pm. Full hour of Lamar and Phil opens his hardware, new products and more. That's really cool. Did you key guests on there? Some cool skate board or inline skate stuff. Cool. JP is on tomorrow at 4pm. Make sure you check him out. Deep dive Scott is on Friday. 2pm Pacific, 5pm Eastern and then back to Sunday. We got our sometimes random hacker evenings. It's been happening like 8 to 9 now. So definitely a more before you go to bed anyway. Good times. And then Mondays are normally certified on meetings at 2pm Eastern time and then Tuesdays is the product pick of the week with JP. That's 4pm Eastern time or 1pm Pacific time. And the mornings of Wednesdays we're doing this and then later is that full block of shows with show and tell and then ask engineer back to back. Very cool. Right, it's gonna be it for this show. Thanks everybody for tuning in. We'll see you later tonight. Again, we're hosting the show and tell so we hope to see ya. And good luck on Iron Maker endeavors. We wish everybody good health. And with that, don't forget to make a great day see you later tonight. Bye folks.
