 Everybody in Pedro's creative tech here, Adafruit, and every week we're here to share three printed projects featuring electronics from Adafruit. That's right. This is the show 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 their show, you can say hello by hitting up the Discord chat room. We have a URL, invite URL for that is discord.gg slash Adafruit. We'll take a moment here to welcome everybody to the show. Thank you so much for joining us this morning. Good morning, good morning everybody hanging out all over the world. We're checking out all the chat rooms we are on Facebook, on YouTube, discord.gg slash Adafruit. And on Periscope and LinkedIn. Giving shout outs to everybody hanging out all over. Liz, BlitzCity, DIY, hanging out in the chat room. Hello everyone. Good morning Liz. Duwester. Good morning Duwester. Thank you all for joining this morning. I just upped the gain on the microphone so let me know how that worked out. And we will adjust accordingly. It didn't sound too low, but I had my volume down. I had the gain lower because I did a voiceover yesterday and I have it low normally for those voiceovers. Good morning Dan. An audio check. Our audio check in the mornings. Cool, good morning. Good morning Rosanne. Yeah, we'll shout folks out as we get to it. Yeah, it's gonna be low. No, it's good now. It's good now, good. All right, well let's kick it off with housekeeping. So let's head on over to Adafruit.com slash free. Find out what are the free deals going on this week. While supplies last. I am seeing some stuff here. So for orders that are $99 or more, you will get a free half size Promo Proto breadboard. That's that lovely PCB that has through hole plating and three color sold screen. Very cool. Very nice for all sorts of projects to get your stuff off a breadboard. And if you spend $149 or more with Adafruit, you'll get the half size Promo Proto plus a free KB2040.

Good afternoon and night to everyone hanging out all over the world. We've got a couple more joining in. Hello. Good morning. We're just missing Yanni for our gifts and memes. I'm seeing that the audio is still low. It sounds pretty high on my end. Yeah. I'm seeing it's kind of low here, but I'll turn it up a little bit. Bear with us while we fix the thing. Hey, what's up, folks? Welcome back to another 3D Hangouts. My name is Noewe Revez. I'm a designer here at Adafruit. Join me every weekend with the prior. A little too early. Yeah, this is better. I'm seeing the meetings are finally going up to zero. So it was the input level in the system preferences for the macOS. So I just turned that up. It should be better. And I'm speaking to the microphone. Now you get to project to the microphone. I'm aware. Good morning, Connor. Howdy. All right, let's go ahead and jump into this week's project. This week's project is this lovely animatronic robot from Obi-Wan Kenobi. Inspired by Obi-Wan Kenobi. Lola 59. That's that droid. We don't want to spoil things. So we'll just say it's a droid from the Kenobi show. That was from last week, though. And it's like right at the beginning of the first episode. So no spoilers there. Cool. So it kind of resembles those robots from Batteries Not Included, but also kind of like a ladybug. It's got these two wings that are server controlled. So there's two servos. You have two sort of eyeballs here. They have neopixels. One is a neopixel button. And the other one's a neopixel jewel. So you've got 12 of eight neopixels. It's running off the Itzy Bitsy RP2040. That's that lovely board with tons of pins, GPRIO. It's great for embedded projects. And it's all running circuit Python. Of course. The code for this one was written by Philip Berges. Yay. He does all the awesome animatronic code for our projects. And this one, you might remember it from a couple of years ago. The Terakko from the Legend of Zelda was the droid we did. So this one is pretty similar, but it has two servos instead of one. That's just the magic of being able to rearrange your components into a completely different body. So big ups to that. And edit the circuit Python code. All it had to do was adjust the rotation and the colors for the LEDs. And it was good to go. Just add some of the trellins. Update the pins. We're using, instead of the Bluetooth NRF52840 for the Itzy Bitsy, we're just using regular Itzy Bitsy, no wireless communication with that one. Yes. And it should be in stock. Yeah. So it just kind of autonomously does its thing. It's randomized for the movements in the NeoPixel kind of animation. Which we had to make too, because there's just so freaking cute. One of the other features of it is we wanted to make this a shoulder mountable bot. So we have these magnets embedded and they are able to attract ferrous metals. So like this is one of those shoulder-mounty little things that they have at Disney. And this attaches pretty well to that. So on your shoulder, you're able to attach your little robot and have a little shoulder bot. And of course this can attach to any magnetic surface as well. So cool as a, like a recondensis robot. You do have enough space in here if you wanted to do like some data logging or like CO2 sensing, temperature sensing, and log all that data. You can actually use that as an actual functioning robot. You can add all those inside of the lower compartment. Everything is together with these little snap fit. So you have a bottom, center, and then the top portion here. One of the other things too is you have access to your USB port. So on the back here, you can see the USB in there. You can attach that. And you also have your slide switch. So you can turn the circuit on and off. It's a bit, it has a rechargeable lipo backpack attached to it. So you can recharge the 2000 milliamp hour battery, which should last like a whole day at the parks or something. When you got back, it only took... I have the brightness all the way down to 0.1. So even with that, it still looks kind of bright and overblown in some of the camera shots. Yeah, but it looks great. You get this nice kind of blue haze. So it looks good. Yeah, so this is the smallest that we've been able to get our hinges for the wings. Before we use like a M2 screw and it still ends up being like a pretty wide knuckle for the hinges when we model that. So we're using a paper clip to hold everything together and that's like about 0.8 millimeters thick and allows us to make the hinges for that way smaller and hide that into the underside of the whole droid. Cool. Would you say the most challenging thing about this? What was the wings? Yeah, getting the wings to flap up and down. So originally I was going to have, you can kind of see like a vestigial leftover geometry here. I was going to have these and you can kind of see the hole there like some sort of linkage to have that attached to that. But it was a little bit complicated. I wasn't able to figure it out in the, what is it, two, three weeks that I had to work on this. So just having gravity allow the wing to flap up and down seemed to work pretty well. So I went with that. Didn't have to do any attachment. So it made the assembly of the wing a lot more easier. And when you have kids, the first thing that they're going to do is try to move the wing up and down so that definitely helps in it not being stripped or being unsunk with how the horns are. And that was a good way to simplify assembly and cut down on it being your chances of breaking it. On the inside you can see you have two different servo horns, two different designs because of the way that they're mounted. These are just attached to one pin. So I didn't have time to sort of bug Phil B to have two separate servos doing one going up, one going down like you kind of see in the show. So I just settled on having one pin control both of the motors. And for that you have to mount them in a certain way so they're both positioning the same way. Yeah, they're not mirrored. It's just positioned equally. Meaning one's not flipped over like the other side. I did have it that way and quickly realized, oh yeah, in the code I'm not going to be able to have two different objects. That is of course a nice jumping off point if anybody wants to go ahead and take on that challenge and have two separate wings, you know, or two different... have it attached to two different pins so you can individually control the motors. But for now it's just controlled by one pin. So the functions are mirrored. Kind of the same thing with the LEDs too. Just to make it simpler I didn't want to chain them. So it's just two that are connected. Both LEDs are connected to one pin. And it kind of works since we have a jewel inside here. You have the little spinning animation that you could add on there and then just one Neopixel button PCB. It is for the smaller eye. Cool. Some of the details are really hard to do as well on the outer shell. Like doing all these kind of groove and cutouts. That is very, very challenging. Yeah, I was spending too much time trying to get all the detail in there. So it is a simplified detail of it. The rest was spent in figuring out all of the mechanics behind it and getting everything mounted inside. I think it was like two weeks ago I had like... the way that this was being assembled was like with a twist. And that was not the way to go because of how the wires would be. It would like all, you know, tangle. So it's a nice little way to do the snap fits. There's a clip that goes into these grooves on both sides for the bottom and for the top. And then the antenna. You do have some play features here. So you do have the ability to move it up and down. Same way for the assembly. We have a paperclip wire that is holding that together. And for taking this on the go, like if at a convention or something, you do have a stowaway mode. So you can actually put that all the way down and make sure it is nice and secure in your carry-on. Speaking of carry-on. Oh, Translucent domes to have the diffusion go through. Right, they're printed domes, printed in Translucent PLA. The diffusion works here, I think, pretty well. You get some kind of hot spots, but it kind of adds to the texture of it. The paint, I'm using like a high sheen acrylic paint. It gives it like sort of like a car. There's like glitter and like sheen on it. It gives it a nice little weathered look too with the way that you can kind of see the paint strokes on there. It did take about, I think, like five coats to completely cover it up. So you printed in gray and then paint the red in. I did try doing red and then painting the white on that, but you definitely have to get... Yeah, it looked flat, the white paint that I had, so I definitely recommend if you're going to go that route and get like a shine sheen metallic white, I think they do make it. With other props, we really try to avoid finishing. This is something we don't spend the time on because we're kind of limited on it, but this just kind of shows that you can kind of get pretty decent results without finishing, but definitely can do that. If you all want to do that, you can do all sorts of finishing techniques. You can sand all the bits and color them, maybe even add some of the detail back in that we weren't able to kind of replicate and add. But yeah, very nice kind of paint job. Those two tones really make it what it is. Every single part requires supports, unfortunately. There's just no way to get around it. You can definitely tell on the bottom here. I did try printing it the other way around, but that's where all the mounts for all the PC boards are, so I can't really get the tolerance on that wrong, so it has to print with... I think the degree of supports that it requires is 50 degrees, so pretty much this entire thing was all covered with supports, like the center and the top. The wings as well, supports all over. Even the dome, I even added supports to the dome. You can try it without. You will get definitely a lot of overhangs. For these curvy parts. All right, so the real test was bringing this out into the wild. We had an opportunity to go to Hollywood Studios out here in Orlando. They have something called Galaxy's Edge, and it's a spire post. It's a very immersive, Star Wars-themed land here in Orlando in Hollywood Studios, so we thought, let me bring Lola, and we brought Lola. Happy to report that we were able to pass through security with no issues. The security guard, the cast member, was all like, oh my God, is that Lola? Is that 3D printed? Does that have Servo? He was very... All like trying to hide, you know, while we're getting our shots. Super welcome, so it's good. Everybody. Aerosolentations are not allowed to have helmets or full body costumes, because the folks can get... So anyway, we were able to bring it in. No problems. We had great comments. Let's take a look. Yes, there it is. We are using that magnetic shoulder mount thing that we were talking about. So that's got the neodymium magnets. They're really strong, so you didn't have accidents, didn't fall. And you just have so many nooks and crannies at Black Spire Outpost. The Galaxies Edge. Here is... I forget if it's like a restaurant open. You can have Bronto wraps. This is like the Butcher area. But we were really happy that we didn't think like, oh, let's just start putting it around surfaces and kind of hanging out. So this is in that same area. And on a ride, this is the Star Tours right outside of Galaxies Edge. And, wow, this thing looks fantastic with the lights and everything. Yeah, so really hitting the home, the part of it being a companion bot, there's like a light on there, so it definitely helps lumenate your pathway. Sure. Like we were talking about earlier, the jump and off point for this, you can add like a CO2 sensor or like humidity and temperature and have that like be... have that data be logged and you can actually use this as a sensing robot. Because it is running CircuitPython, you have your file system on there, so you can store you know, the rebel base database on there. So actually have real data on there in terms of not just text files and images and all that, but actual temperature. Yeah, I love the CO2 levels in that bar. Yeah, so Olga's canteen, we got an opportunity to make reservations several months ago. We were able to get inside Olga's canteen and it was really fun for the kids to see the DJ Rex animatronic who is the DJ there. Droids are allowed, they do serve their kind at that canteen. So that was really fun to hang out and shout out to the folks that we met there. They are prop makers and they were showing us some of their props. They fabricate stuff out of EVA foam and leather and all sorts of cool stuff, cool fabrics. So it was really cool to meet those folks. Yeah, and on that point definitely brought out all the people who were into making models and the cosplay stuff. So definitely really cool to be able to talk to those people and show them the Adafruit website and be like hey, you can get a bunch of electronics there and then it's inspiring that seed in people's head one of the kids that came up was just like oh, how do I get this? Bro, you gotta print it. So it definitely probably opened up his eyes and made him go crap. A thing that you really like, that you want to make that you can only make will definitely push you over the edge and try to get into getting a printer and figuring out how all this stuff works and that is the main goal of why we made this. We release it for free, you can use whatever electronics you want. It's not fitted to the Adafruit stuff but you can get your skills and remodeling some of the components or the mounts for that and hopefully inspire people to get into this whole all of Disney. It's hopefully trying to inspire you to become an engineer what they call an Imagineer. So this is why we do this. Yeah, it was really fun to bring it. I had a lot of fun filming it and everybody everywhere we went was far away. Oh my God, is that Lola? So I definitely had to keep it a little bit hidden too. I didn't expect that many people to recognize it from so far away. People, like I said, the cast member knew it was 3D printed and asked about the servos and folks are more knowledgeable. And what's so cool about this is yet another thing to point out is the actual official Lola toy Elamatronic won't be released until August so we were able to get this out the whole month earlier before I'm guessing it's supply issues or whatever that the I'm sure they were trying to keep it hidden before the series came out. So it's really cool that you can print one out for any of the official ones come out and you can completely customize it however you want whatever colors. Oh yeah, it was sprinkling so we were able to survive a bit of sprinkles even with all of the open how open it is. So yeah, let's go ahead and jump into the learn guide spent half an hour just giving the synopsis to why we even made this. Yeah, I mean, it's just fun. Rarely do we get to bring our prop to a land dedicated to Star Wars so that was a lot of fun. Yeah, like when we made the lightsabers we could bring them then so this is nice and small if it's in your hand. Yeah, it just fits on your shoulder. So yeah, this is the Lollabot inspired by the little amatric that young Princess Leia has throughout the series. Only thing I can't do is fly around and I didn't have enough time to put like sound effects on there but definitely room to put a one of the smaller speakers inside there. It was funny because somebody or the fellow asked us at Olga's canteen, like, does it have any sounds? Well, you wouldn't be able to hear them anyway because it's a super loud bar. That's a good point in terms of there's always a compromise when you're engineering stuff. It's like, okay, I can't add the detail because I need to make the wings work. I can't make sounds because I need to shoot the whole video. So the main goal was like, how do I get the shape right and how do I get these wings to keep going. Yeah, so you got the two micro servos the itsy bitsy RP2040 you got the lipo backpack the slide switch and then that honkin 200 mAh battery which will give you a couple hours of playtime. You got the jewel it has seven neopixels and a neopixel button which has the same one neopixel and those are all the parts. Most of them are in stock except the jewel but I think you can't replace that jewel. We have the other jewels, the the warmin Oh, they have RGBW Yeah, yeah, yeah. So you could always scroll down here and pick one of these probably the neutral one. Yeah. These just have that extra light so that could be something you want if you want to play around with that. Warm white or cool white you can update the code I think the neopixel object just gets a little extra add on but we have plenty of demo code for both neopixel types especially RGBW so check that out. You can always, you know, change out the part that should have the same diameter so you're good there. And then our smallest neopixel is the mini button PCB and that was in the smaller eye. Yeah, these are great. You get a pack of five for five bucks rechargeable lipo battery some of the little ancillary type stuff which is a hero. I don't know what to call ancillary it's what I was the easiest way to build connectors I want to say the male and the female header sets. Okay. I definitely get those and I'm just using those because there are three different levels on the whole body and I needed to I needed a way to easily connect those without doing like the jump. What I usually use is jumper cables like snip those off and have the female and male but those are so long the header ones are a lot more smaller so that was definitely the way to go and then just some cap-tongue tape I should have added that on there we have the strips of the for insulation. Yeah, it's budget tool because you're going to need that to disassemble because of the way that it snaps in it's super simple. Yeah, it's pretty it's in there. You probably break a nail train to get it off. I disassemble it. Magnetic pin if you want to have that the magnetic pin there it is magnetic pin if you want to have it attached to the things which we didn't even mention if you go to the overhead nice fellow has already modeled a Lola bot and included the feet for that and we're like oh I don't have any time for that maybe it'll fit and the scaling is pretty similar. Yeah. And so we could put magnets on the inside here just press fit those in and they would go right on to these existing ones you can have little feet. Yeah, this is fantastic. I'll quickly show it was going to show it for shop talk but yeah let's save it for shop talk just don't forget look at the Thingiverse file if you're looking for a Lola bot with a bunch of details it's kind of the only one right now this reporting on Thingiverse but we'll talk more about that during shop talk yeah I haven't put any links in though. Yes it's your hosting you want me to entertain while you do that oh I can also see the comments real quick Dave Darko saying yeah he spent 10 hours and just detail himself can relate yes I did not want to get a track. Dave so Dave is building one as well oh okay. Very detailed. Yeah I wanted to make it as detailed as could but man like you're saying that's 10 hours of do all the other stuff too shout out to Dave for doing it up. Manable to say it would be cool if it could relate to sound yes it's an excellent idea. Oh like sound reactive proximity sensor light sensor. Yeah I mean you could stick the proximity inside of the bigger eye. I hope this excites people to think about some other ways to do it there's so many you can reorient how the components are inside so there's definitely space for whatever you want in there. Cool alright let's head over to the circuit diagram real quick. There's a circuit diagram for this it's a bitsy I sort of updated this to not have the nrf2840 I'll have to update this again. Okay it's pretty similar. It's the exact same pin out same board dimensions just a couple pens really one data pen for the neopixels they're sharing data ground and voltage and then the servos are also here in ground voltage and the signal pin. So you can change that up if you want to use like an Arduino nano or something else you can do that just change up the pin and you know if it's for your python compatible so we got all the pins are laid out here so you can always reference that for accessibility purposes and we created this in fritzing fritzing software which you can pay for or get it, compile it yourself for free so there's that to get all the fritzing objects and post the leak in our github here where you can get all of the parts for that if you want to build your own circuit diagram yeah you can get the batteries and all the boards and the neopixels yeah cool there alright circuit python page is a married page from the itsy bitsy rp2040 page so this will just walk you through the steps of getting into the boot loader, downloading the uf2 file which is the firmware for circuit python and then you just drag and drop it because it shows up like a USB flash drive so you got all the documentation here for installing circuit python this is running circuit python 8 which is the latest version at the time of this recording let's check out the code page shout out to phil b again for putting this together in the previous project we just updated the servo kind of the settings the rotation for it and the neopixel count and the board pin so everything is kind of written out so you can adjust it as you like if you want to do a different neopixel like the rgvw so you can change that here in that pixel object so what did you change for the servo kind of scroll down instead of like 180 I think it's down to like just 80 it's not doing that full rotation that it was doing on the terrica robot so you don't need the because it was for a head you don't need to rotate all the way around for the wings it's literally just that one little bit looks like most of the settings a lot of it is the same you can check those out and see if you want to change the hold ignition position for a second it does that so you can change that if you don't want any hold I haven't played with this myself too much but in the end position yeah I was just able to again I am not a coder I can't read what it's saying but code wise I can't understand what any of these minimum plus negative 10 I was just messing with what I thought was the in and out points which is the next position 7 I think that's where it starts so it's not slamming the horn onto the base it's a little bit raised so you have some leeway in case there's some slop or something in the way that the wing is put together it's not going to slam into anything and it's not going to stress itself stripping the motor trying to raise the wing higher than it can go so that's what I was looking out for you know when you are assembling the servo horn you'll want to be right next to new editor changing the position trying to place the horn I'll show it in the assembly part where to test that out here's what the circuit python drive looks like with all of its libraries the bundle fly if you click on this button here project bundle it'll pull down dynamically all the libraries that are needed so you need the neopixel library the a different motor library and all that gets packaged together for you just by clicking download project bundle which is really nice still amazed about that feature in the learn system really nice alright on to printing couple parts we have three main parts you got the inner plate the bottom plate and then the topper and then the wings and the domes and the servo horn and the antenna still though it's a good small amount of parts small amount of parts but they each take around six hours to print the body parts it's because of the resolution the speed and how much support material is going on there so for the layer height I forgot to put one setting on there it's the adaptive layer so you want to it's not too new it just adds more layers for where it's doing the curves it'll add more layer height to it alright and then 10% yeah 10% gyro landfill 60mm second good the supports we're printing that lower extrusion with 0.2 easier to remove the densities 4% and overhang at 50 so anything that has a 50 degree angle will get supports and that's what we want for the bottom and the top one the center one that would do it as well just because it'll make the smoothing of the way that it arcs over so it doesn't crush any of your components that are on the inside there okay brim for the adhesion so we get a nice little adhesion there and then the painting I'd show the brand that we use it's the deco art extreme sheen okay cool there's the red I was going to try a darker one but I didn't know if it was how did you get my airbrushing it I didn't want to it was a timing thing I didn't have time to go in there and mask all of that out like get out the airbrush so this you didn't mask any of this no it's just a paintbrush it's a whole hand freehand yeah it's getting using the because these do dip down the groups for this yeah we'll use it as a line as you saw from afar it looks good it's a prop the further away you are the better it looks we have some gifts finally from Yanni let's check this out yeah that was one of my goals there to make sure it fits in your hand I totally wanted the wings to rise as high as it does in the series but it's crazy it has to look around the pupil yeah that's a lot of detail wow alright get him back over alright so that's the paint a little tip about the paint you can freehand it assembly definitely dry fit the boards you can get the measurements for each wire that you're going to need go to the first one you can see how I'm doing one wire that's split off so like for the ground I'm using one wire and then twist those with four other wires together to create sort of like a spaghetti or a squid that has all of your ground connections because you're going to need one for the lipo charger the neopixel and the servo yeah it's hard to get like a small ground bus in there so this is a good method there's just silicone coated wire so they're nice and easy to bend around they're not going to melt when you're soldering other stuff together that's great and plenty of heat shrink there there's a good look at the headers there the connectors there so I'm using the male headers on one side and then it'll connect to the female on the other side so you can string those through the different levels yeah you need to be able to disconnect the components from the lower area of the board you could but if something messes up you're going to have to unsolder to get to the bottom it's not a good way to having connectors is not going to work for the top because there's no way you can fit the the jewel through the eyes it has to go on the other way through the top and then connected yeah so this is a good method then it's a little bit more advanced you definitely want to have a little bit of soldering practice before doing this this is your first way to go moving on to mounting everything the magnetic pin fits on the bottom there and the board your completed circuit board fits right on top with space for the lipo backpack on one side and the little cut out for the slide switch on the other yeah there's little clips on the corners of the PCBs so that's what's keeping them in and then the kind of standard holder for the slide switch you want to orient the USB port to the opening there so you can see that nice little channel where a USB cable can plug into cool and servos just getting into the kind of little mounting plate? yeah so this is the center body the servos, the little servo mounts have fillets on one side and you want to put the mounts for the servo on the other side of that fillet so there'll be a nice flat little mounting for it that is laid out you can see here the right one when you're looking at it these two holes are where the eyes are so when you're looking at it that way the orientation, the right is going to be the smaller server horn and the left will be that longer bigger one it's because of the way that we were talking about how they're not really mirrored it's like stacked so you can have the same action for the wings mirrored and you can kind of say I have a cutaway there because I had designed it with thinking that you could mount the servos opposite of each other and I didn't think of one's going to be rotating 90 to get that same thing you'd need like negative 90 so I'm not able to code that so just stack the servos the same way orient them the same way so that's a nice little visual cue though that little cutout that is on the center body part that is where the left motor so the left servo horn that's where that goes, the longer one looks like you just coiled up the cable too so you're going to have to optimize the wires for that so I didn't want to cut them so yeah coiling up making a nice little bundle of the wire for each one is definitely a better way to go if you don't want to cut it and that will clean up how much room you have on the bottom there you don't want the wire squishing all together so we go to the next photo here you can see how that gets threaded through you have just enough room to connect the bottom there roll down a bit you can see here how those are aligned together the bottom and the center the little connections for the LED eyes they're going to pop through the center and to the top you can connect your servo and all the other connections together you can see here why we did the males on the bottom and the females on the tops because of the servos have the female connectors on them those fit perfectly in there connected and then you can align those up and press fit the bottom and the center together and here's where you can test out the servo horn arrangement so when you turn it on it'll reset its position so you'll hear like a whoop it always goes back to zero it starts back at it's going to be like seven so that noise there as soon as you hear that turn off your circuit so you can arrange how your servo horns are you can see here there I think I just popped my slide switch in there you go when you turn it on and there you go that's where it resets yeah so that's where you would yeah so it'll go back to reset at seven degrees and that's where you can position your servo horn and that'll be like the starting position and that's how you can like sort of sync them or calibrate them so the servo horn is attached to the 3D printed arm is that right no the arm is attached to the servo the what's it called the horn part you can see it there it's attached and then you use the two screws that come with it to secure it in place that's what I'm saying so the servo comes with horns and you're using the stock horn no you have to use a completely customized horn because it has that little arm attached to the spline it pops right in and press fit yeah press fits in and you have the screws that will secure it in place definitely use the screws because it can pop out yeah yeah for sure alright so that's how it's secured a lot of times I'll make an attachment that attaches to the attachment you know what I'm saying like I'm doing that with this droid I wouldn't have enough room for it because the way it's mounted it's almost completely flushed to the bottom base here so I don't think I'd have enough room cool you're completely replacing the entire horn nice you're just using the screws that come with the servo each of the servos alright I think you're putting together the wings here wing assembly we're just using a standard metal paper clip some of the paper clips that look like they're metal they still have like a clear plastic sheathing over it so you want to take that off and then using pliers and a precision the little noodle nose flat pliers you can use those to bend into a slight curve so it'll fit through the bodies and the wing hinges and then you'll just bend the end so they don't fall out and then you'll do the same thing with the tail assembly alright that's pretty much it the orientation for the tail make sure that the chamfer that I had a little cut off make sure that's pointing towards the eyes and that's so that you can put it in stowaway mode so the tail flip all the way towards the body move on to the neopixels the way we're connecting these are again with the header pins you can solder directly to the PCB button neopixel wire it up that way so the pads are on the back of it you can kind of see there that I marked where the ground is for each one of the parts just so that when I'm connecting them through the bodies it's easier to align the cables so we're using the sharpie I think it's like the oil based white and that seems to go on many different surfaces so it's a nice little way to mark things so once they're installed to the eyes you can connect them up yep you'll line up your body make sure that the USB port should be on the back and the side switch is on one of the sides and that's it just press fit it should snap together you do your little test there attaching the diffuser domes and that's really the last part yeah just press fit in last part here using skate lubricant to help the wings flap smoothly just added like a drop to the hinges right here and that's just to make it super smooth you could go in there and really clean it up with sandpaper or something but having that lubricant on there is definitely going to help that's pretty much it if there's any like you kind of see here this one stays up a little bit I've bent the paper clip you can adjust that by twisting it that's pretty much it got yourself a nice little animatronic lula here's the stowaway mode I was talking about so you can have that all the way back more front and there you go a nice super cute so cute I had to be able to and of course you can play around with all the different colors all of the different the shines that they have and of course the material if you don't want to do any painting at all this is that glare red which doesn't really match what we see on screen I think it's closer to what this red is but there you go you can have your Imperial Lola or good guy Lola Rebel Lola there you go attaches to the these I don't know if they sell these separately I'm going to find like a stock because I don't think this will be our last companion box like shoulder puppets and this just happened to come with one of them we've got it's super comfortable it's got like all these yeah it's like just removable is it come off? there's a glued in place I think it's glued I wouldn't remove it we only had one and we almost lost it at the galaxy's edge so yeah there you go a nice simple way to make a little companion but yeah simple stuff though so cool alright we're going to jump into shop talk or for the prototyping I want to talk about this the feet this came out last week a very detailed Lola bot on Thingiverse so this is from Prop Vault posted up on June 24th Prop Vault posted this up and has a lot of details to their Lola build so you can see the feet here and the top part has all those bits and all the embellishments you can see like the kind of faux I don't know electronics I guess components on the outside? yeah so it's really cool for the details so we took the feet and kind of optimized it a little bit so right here I connected those two things and you saw in the overhead that I kind of added a little bit of geometry so that the magnets would stick in here but yeah it's so there's a press fit? yeah I got it in there play with the diameter it's wrong but cool that we can kind of bring that into fusion and modify it a little bit yeah matches pretty dang good so shout out to Prop Vault for posting that up it's already got quite a few makes so people are making a list so yeah give them a shout out there to Props and as we see more we'll probably chat about them and post them up on the blog and stuff so very very cute design in general for this upload a remix for the legs so yeah super cool lots of good details on that I like all the little greeblies everywhere pretty with no supports you can see here that there's the new side see all the boost filament they came out but yeah that's what you get pretty cool yeah someone kind of get it on there yeah we did in the photo oh you can't see it on there overhead yeah looks great so just a quick little shout talk there alright cool what do you guys think they approve approve approve approve another shout talk fit oh yeah the engineering the Star Wars themselves released the I think it was Hasbro they released a video on how they engineered it and you can kind of see a couple of the components on the inside they did like a intersection view so you can see all the components on the inside yeah they actually showed CAD and they showed some of the internals they showed their prototype I kinda wish I had the video here just search for Lola on youtube and it's from Hasbro Pulse the folks that make a lot of the high quality props for Star Wars what impressed me was just the way the layers how they did each of the different body layers like that's exactly how I did mine to see how that works of course it was pretty high level so they didn't talk about how the motors function because I was really interested the way that they call them ears I thought they were wings the way that they flap up so fast yeah I think there's some sort of mechanism that's like pulling a string we'll find out when it's released we'll obviously get those to take one apart and see how they're doing the motors for that yeah there may be a shortage of parts so we'll see but sometime later this year in September or August or something then there's gonna be a toy version as well that probably won't have servos and stuff but yeah we'll see it should be interesting to see how all those are manufactured or servos that are using on the inside maybe like the little tiny Polola ones so it's super interesting to see how their LEDs are all structured and all that so super cool cool way to get interested in toy making yeah totally alright another top box check out the Lair for Lair we did last week it's on making geometry for like holding hex nuts parts together you can make some geometry that will hold your hex nut in place so check that out if you want to learn a little bit more about you know sketch constraints and just using the draft tool infusion 360 to kind of avoid supports and stuff check that one out okay what are you prototyping you got 10 minutes here so I'll quickly show off the okay we got more droids this is an IR remote I lost the remote for my TV so Lamar thought it would be a fun idea to make an owl to make the remote into the shape of an owl so two IR LEDs here we have an arcade button to turn the TV on and off that's all it's doing just turn the TV on and off and then you can use the IR receiver to take in some of the code from an existing remote and then that's on the space it'll be next week's project it's a nice simple one shout out to Liz she's writing the code for this one it's kind of already done we just need to start doing the learn guide but yeah IR LEDs remember the TV begun it's kind of like a TV begun but we'll document how you can kind of sniff out you can sniff out um gosh I can't think with these I cannot think with them I was hoping I wasn't too loud for people I just can't think now anyway TV remote it's running off the QT Pi RP2040 and gosh I don't know what else to say but other than I had a lot of fun making the owl shape it's completely hollow, it prints without any supports this is like a little plug in the background just so you can get access to um the button the LEDs are press fitted and there's a little promo proto in there the quarter size just to get some grounds going I have room for that and then I have the 3D printed snap fit holder for the QT Pi you can see that there I've used this in quite a few other projects now I just keep reusing that part because it makes it so that the bottom is modular get to it use a different board, maybe you have a different Arduino board that can do circuit by-thon then you would use that Liz is saying that she used the IR signal reconnaissance for this project yes reconnaissance and you got your snap fit base there for the owl you have some screws to attach the owl you can feed your owl all sorts of IR signals yum yum it likes to eat likes to eat IR signals are in the shape of a mouse and uh very satisfying snap the LED turns on when you press the button which is not cool it's going to be powered by USB and that's it and that's it IR owl very simple clean owl shape this is the best you can do it later the owls are not what they seem that's the uh that's the uh reference from uh oh boy, is it Twin Peaks? I think it's Twin Peaks well we know so much pop culture alright we got a couple minutes we're going to catch up on some last week two weeks ago, thequisitor lightsaber super cool forever I kept failing on me they took like eight different tries I finally did like the 45 degree overhang supports for it so there was just supports all over the friggin thing with like a 20 brim bottom for the adhesion and that finally worked the only thing I was unable to do with the other ones had you could like this slides in and out you can do like the half circle and slide over to do the full circle those parts weren't able to get printed out but the entire whole piece fitted and it fails nice in the hand I like the little detail here you have the um you can add a uh saber or tube or something to it and just a tiny bit of detail with the red and the gray painting there go ahead and drop the link to the thingiverse the uh safari crashed uh Arman's designer I'm trying to get the designer credit I can't go faster sorry folks it literally crashed the uh the notes crashed from Arman de Laurel yep there's the thingiverse link it's a free download off the thingiverse sorry I can't get to it right now hey buddy oh look we've got a haircut alright yeah our dog just got a haircut Rufio's very happy Yanni says that the lightsaber looks like Stargate on it I like the air bash air bash whatever writing that's on there nice little detail on there it's not like Jedi writing or anything I think it is Jedi writing I don't know what it says but it looks really cool as a detailed texture it's in there uh for thingiverse oh I posted it twice hey what happened is it gone Pedro? uh wow well let's see that's the first now what's there why didn't it work for me let me post this link again is that the same one the second link you pasted was wrong or something oh it's because it's strung okay it's just weird delete that one yeah fantastic design by the Lorell on thingiverse for their last time Armin very awesome builds it can swivel yeah I'm so set up I wasn't able to get that part printed part times is tough to do it's so big it's one of those like 24 hour prints or whatever it was that says in the thing very very cool though yeah like the scaling of it feels nice in the hand only thing is missing is having like the hollowed out so you can put some LEDs and stuff in there maybe the maybe the magnetic LEDs would definitely fit on there it's just like getting the tube to go on there okay can you put the second link then and then this week's community make is a gunk droid gunk it's just any gunk droid it's a bobble headed gunk droid this is by Joel Caval for posting that up it's a free download is it a free download sorry but it has this very interesting kind of spring mechanism it's just a spring kind of shape yeah it wobbles really nicely wobble wobble gunk it is an excellent reference for that spring kind of see it here gunk gunk yeah it's a very nice spring for bobbles Joel also has a wide collection of designs that feature this mechanism very cool um pictures got the link here two legs make a bobble more yeah that would be pretty funny yeah more accurate to the design garbage bot yeah but excellent reference for the way that the spring is made on that and it looks like it was made as a motor mount for your printer nice little visualizer to make sure to see from across the room that your printer is indeed extruding you got Lincoln R2D2s yeah check out their youtube channel as well Joel has a great youtube channel so check that out I think the gunk one though is definitely what the characteristic of the bob bobbing is what fitted to best gunk gunk yeah here's the collection of all other different ones and this is great TARDIS oh somebody remixed that uh treasure chest puzzle into a Zelda themed one looks excellent cool so much great stuff here check it out very very cool alright well that's this week's uh what do we need to make we'll have to do them next week there's a good list of them so we'll have a lot to do next week with the owl there's not a lot going on so we won't spend an hour on that learn guide there you go alright I think that's gonna do it for this episode looks like we're right on time don't forget to go anywhere later today we still got a full uh list of shows yeah we invite you to come on the show and tell and share your projects retro gear anything like that you can come on the discord chat room at around 720 ish we'll drop a link in there it's gonna be hosted by Lamar and Phil Mr. and Mrs. Lady Aida so full 30 minutes of showing and telling with the community and then uh right after that 8pm uh eastern time uh ask engineer with Lamar and Phil the return of ask engineer so check him out got lots of new stuff to catch up on um but yeah tonight show and tell we'll be there and hope to see you there yeah please stop by your awesome DIY project you're working on got tomorrow thursdays at 4pm eastern time john pock's workshop check in with john and then Friday you get a deep dive with tim foamy guy every friday at 2pm pacific or 5pm eastern and then wrap it back around normally on sundays uh from the desk with lady Aida as a live stream around the evenings so check those out for uh the great search sponsored by good fidget key mondays we have the circuit python meeting uh with the exceptions of the when it falls on a u.s. holiday we do it on the following day so this week we had a u.s. holiday on monday so that it happened on the Tuesday but normally it's on a monday and then on Tuesdays uh jp's product pick of the week every Tuesday at 4pm eastern or 1pm pacific this week was a 8x8 dot star matrix so cool so check those out you got 50% off or up to 50% off discounts should use it on that r2d2 one huh looks so cool that star little matrix i might do the charlie because it's easier oh yeah yeah yeah forgot forgot dust star's got some special alright well that's gonna do it we'll see you tonight on show and tell but thank you everybody for joining us live it's really fun we'll see you later hope you enjoyed the show and hope you're inspired but until next week remember to make a great day bye everybody
