 We need what is this? This is show and tell and it's us Lady Aida. Mr. Lady Aida back Yours your original hosts. Sometimes we have people the longest daylight of the year Yeah, maybe we'll have the most sharing of the year Sometimes you have special guest hosts, but today you're stuck with us again This is the most fun you can have on the internet with their clothes on for the next 20 ish minutes We're going to check in with people from around the maker community and the aid for community and see what they're up to What are they soldering 3d printing exploring? Dumpster diving coating and more Any other notes? I guess people can come by we're in stream yard, but go to discord if you want to There's a link to show up and more Let's start off with Jepler and then we'll go to Aaron after so okay jebler Going on. Hello So this is turned into a real collab effort because the more let off with This is Teddy Ruxman by the way More let off with starting to figure out the audio formats based on hi. I missed you With figuring out the audio formats and how to encode samples and JP investigated software for turning like an audio track into mouth Movements and he found a piece of software called rhubarb that does it and so I put together just a little quick Demo of that so this is custom audio running on Teddy Ruxman created by a Python script with mouth movements from rhubarb But this video is to show off the advances we've had with converting audio files and creating mouth movements And that's not Yeah, the code is not ready for primetime, but it's on github I'll drop a link to that in the discord and I hear that these are not very expensive to buy on Yep, eBay or whatever Teddy Ruxpin and the ones that came out 2017 The shipping is more expensive than the bear. I just sorted by price and they're like $16 $20. Yeah, I got my friend 12 bucks yeah, and you know the launch price was like 200 bucks or so and these are those that's just No, it was like 60 bucks, but it was like 200 if you want to buy it like new and box No, I'm saying when they launched Yeah, they were they were they were spent so and then the ones even before that the 80s was a cassette tape ones So this is neat for robotics. It also gives you a chance to learn about puppetry and Very before the show is talked about this since the beginning of it if we're like with our puppets with like adobot and Cricket we've always wanted to have an imagineer in a box if you've ever visited Disneyland There's like watch AI that yeah, there's a there's a there's David the teddy bear with that as well Something about teddy bears and animatronics. I think it's a trick to get us to trust the AI Yeah, anyways Or make AI friends make robot friends that robot enemy But they're really neat and it's really hard to get all these servers and everything working together So you could just get one in and just do the software side you need to modify them Physically, but the other neat thing is you can go online look at some guides that other people made like years ago In this first came out and you could take the fur off and put any type of other Stuffed animal creature ideas so for people who do companion bots or we're gonna make like Figment the dragon one. Yeah, it's just like the core is like, you know It's just like this. Yeah, there's a hard plastic part in the inside But the the legs and you know the the head is obviously some round head But like, you know, most stuffies are about the size you might be able to Got it and put this in I don't know it'll be interesting to see Yeah, yeah good times. Anyway, all right So we'll be doing more with Teddy, but that's what's up right now Fun next speaking of delightful and whimsical things Erin what's going on this week? Hello, I'm sitting here under my fabulous jellyfish umbrella. That's right I went to a music festival and it was a thing like there was there was dozens of these here This is a pretty popular design for a festival totem So a lot of people had them on big tall poles so that their friends could sort of find them in the crowd And this one's pretty fun. It is running W led so I can actually control it with my phone I got some different playlists here and all I have to do is like tap the playlist Will change colors. This is a really cool app. It's got all kinds really easy to use It's got a color modes and palettes and you can make playlists and you can use different color animations It's it's like two minutes to install. So I just launched a tutorial for this Jellyfish umbrella Having a ton of fun with it. Um, I also put up a jellyfish Installation like a large-scale art installation I made like 60 animated led jellyfish that were all wired together and put them up over one of the stages at this music festival And when I walked underneath the swarm of jellyfish with my umbrella It automatically synced up so that it was running the same animations as the swarm above the stage Which was incredibly cool. So I highly recommend if you're into led projects and you haven't checked out W led Do it. It's this is running on a pico w and Not not that hard to build. Well, the easiest way to To try this W led thing is to follow Aaron's guide which just got published So check it out. She goes step by step on how to make jellyfish and sell w led and use it It's your new favorite thing. So And you know leds I've been playing with them for a little while now. Yeah All right. Well, I like I like the aquatic theme and we'll be um showing the the tiktoky youtube short Along with the guide tonight, but also check out Aaron's video That's on our youtube channel as well for the full step by step. Good work A full project. Okay Next we're gonna go to Jp and then we'll go to melissa then scott. So that's on jp. What you got going on this week? Hey, uh, I got a lunch box and this thing is super super cool. Uh, Do you all hold it up? Uh, yeah, let me hold it up. See right here. There you go. Uh, so Animation tool works on it right there and it's got some b and c connectors for video Out it's got some vent fan there. It's got a Another uh a fan there and there's a ac plug input. So this is a weird lunch box And I saw this at an aerospace surplus shop that I was at and I I was like that's I gotta look inside this thing What am I gonna find? So if we go to the overhead, I can open it up and reveal the super cool contents of this thing, which is The video lunch box is cool. So this thing was a frame Essentially a frame buffer that was used for stop motion animation or for 2d pencil tests Where you would have your video camera pointed at your scene or a down shooter on your uh on your animation Hand drawing animation and then an output going to a video monitor And what this thing could do is it could store up to about 250 frames of animation So you would go and capture a single frame. There's a little readout that tells you which frame you're on Uh, and then it's displaying that frame So you would then advance to the next frame while still doing a ghosting or an onion skinning of the last frame So with stop motion, it's really helpful to see where you were on the last frame as well as looping So you could loop at 30 or 24 frames a second depending on if you're essentially doing tv animation Or film animation And you could also shoot on twos just by taking two at a time if you weren't shooting full 24 frame Which is madness for for stop motion Uh, and this thing was pretty revolutionary especially for either uh students like education and animation Because previously what you would have used would be like a vcr or a camcorder and tried to record pause real quick Move things record pause real quick and the timing would be all over the place So this was a a real tool that was used both for education and in professional Sort of a video tap or a video assist for stop motion houses They could use this to see that they liked what they were actually shooting off to film or actually shooting to a higher quality video source I'm gonna see if I can get this thing working and I'm also gonna I think use this as inspiration for making a modern day Uh version of this using maybe a raspberry pi and some video capture Largely because I love the form factor because yeah If I'm being honest the the version of this that exists today that's about 7 000 times better is your ipad Yeah, motion software or your computer and and dragon frame and a camera And you've got amazing modern software for doing stop motion But if you want to suffer and do it kind of the old school way with some really cool gear This is a kind of amazing relic uh and and blast from the past piece of hardware I'd love to know who dap was it could be like Animation production could be someone's name dreamworks. I don't know Uh, I do I do know some some stop motion people who ended up working on 3d stuff over at disney So maybe that but who knows uh, also last thing that I really love about this I've never seen these before they use some really clever hinges for this Uh, which Have a little squeeze clip We'll close this for a second. We'll squeeze clip. Uh, that lets you Remove the top Just like that. Oh, wow You didn't want to leave this hanging off the edge. You might be running out of space and then you can Back down Those things are cool as heck. They're called heartwell corporation made them in placenta, california Um, so this thing's full of fun surprises and uh, the nice thing is I did get it up and running Uh, or I should say I got it booted up It powered on There was no smoke. I opened it up and checked all the caps look at least not bulging Um, it seems to possibly be operational. I got some video Uh to display, uh, but I think I might need to get some proper 75 ohm BNC cables to make the thing happy or it's got a problem that'll that'll never be fixed because this company went out of business A long long time ago and uh, and these aren't there's I don't think there's anyone around who knows how to fix them But that's the video lunch box. I thought that would be fun for I mean, I think there is something interesting about You know I've been thinking about because you brought this on um our creative meeting and you know, you were talking about it And we're like, oh could we make this raspberry pi? You know, I do think like yes an ipad's great, but um, I could see how You know, you could have um A raspberry pi and you can connect You know the a raspberry pi camera to it and then you could have hdmi coming in and you could have You know tactile buttons and like those new encoder knobs, you know, there could be some interesting um Interface that you could do that wouldn't be pop. I mean like yep You know people talk about like screens and cars and how you know modern cars They have like one big touchscreen, but it's like it's so easy get confused when it could be when it's doing Stop motion you want to have one hand on like a knob and the other hand Tweaking a thing and you're like not press not press. Yeah as you're as you're iterating through your scene I don't know. I think that can I believe it Yep, I agree. I like tactile stuff. Yeah, I remember um a million years ago I think I don't know if we were both at make at the same time or maybe this was like make volume one um It was possible to do stop motion with a mac and it was Because the software was finally kind of ready and it was like the the downloadable version You'd plug in a webcam and then you would be able to have the onion skinning thing and that was the the thing that really Helped out because you could see the previous frame and then you could see the next frame And then you could make a little quick time movie. Yeah pretty low res Yeah, that was you know, that was if you think about it like if you've ever done like little sketchbook animations You could just flip the pages. Yeah, that's what would would understand the flow of what they were working on That didn't exist for stop motion when you're doing it on like camcorders and stuff unless you wanted to hit rewind and play super In convenience, so a lot of it was either pre-planning or just straight ahead and you hoped you got it, right? So things like this Helped elevate the craft. This is cool. Um, you might want to do either a blog post or get out A couple photos without a social media because usually when we when we publish these things Someone comes out of the woodwork and like, oh, yeah I worked for them. I was I had the schematics of my basement. You know, you know, that's my old lunchbox Yeah, I looked into it and uh, it was a tube. I think of a two-person company up in oregon Uh, and that was their company. I think animation tool works Few versions of this eventually they did logo a dv Version that could do dv quality video and uh, yeah, there were a few iterations of it, but uh, yeah And show the logo on the front It did every little bit of this They did a really good job on when I saw this out of the quarter of my eye I thought I was seeing like a piece of a crew gift like cartoon network crew gift That's at first what I thought. What is that thing and then I went over I was like, wait a second. What is this thing? So, yeah, this is really neat. Yeah. All right. Thanks. Thank you. This was a combination of school style of retro How much was this was it like 10 bucks 50 bucks? I bought it for 25 dollars. Uh, worth it. Totally What I love asking people because they're like, let me tell you I got it Going right for um electronic lunchboxes and teddy bears on the show this week is about It's good. Yeah Yeah All right. Thanks so much. I agree. Fine. Thank you. All right, except we're gonna go to melissa and then we're Going to go to scommel. So what you got going on this week? Well, I have been working on Updated you're going through all the matrix portal guides and updating it for using this matrix portal New product here has the sp 32 s3 And one of the guides that I kind of updated last here is this matrix cradle game and I wanted what I had to do to update that is I'll wire it up to this max 98 357 and a speaker because The esp 32 does not have the same audio output that the matrix m4 did It only has the it s and so I just kind of wanted to show this working here. So if I just kind of Put my finger right here through here you can hear playing Nice so That is now working. Uh, and the guide has been updated. So all right. Good work and you 3d printed that um base yourself Yes, good work Thanks for I know one of the things is I was like, well, I want to update this hardware But we have to go through all the guides, but you found a lot of bugs and you fixed them Um, and now we're ready to rock Yeah, most of them just worked without any changes, but there was a few yeah This is a good example like oh like an edge case Yes, exactly Okay, thanks so much. Nice work melissa. All right, scott what you got going on this week Hello, um a couple things. Uh, I thought I I'd uh tease this I had this idea of a mounting grid. So these are like 0.1 inch holes at a 0.2 inch Pitch and I think I showed this. I'm not sure it's just like a prototype that I did and then jeff had the idea of doing like a swirl And we kind of just like went for it The more went for it and ordered it in aluminum. So I've got uh this feather here mounted It's with brass. So I haven't powered it up yet. Uh, you have to be aware of that That you might want to insulate the board from the brass standoffs But it's nice and rigid which is awesome and the the brass standoffs are nice and sturdy as well So I'm pretty excited about this and my brain is still cooking on patterns and more, you know one one thing that would be neat is um, let me uh It's a little bit if you go to um any of the pegboard type stores because that anything that you can put in slots and holes like Ikea and Home Depot There's all sorts of stuff that also have other types of weird connectors that they have you can put them on shelves There's other presentations. I think you did this in key cad, right? Yeah, so, uh, I wrote a generator script that produces this pattern. Um Jeff had done it in openscad because he 3d printed it But um one more knew that jlc has aluminum Yeah, bcb. So I wrote a key cad generator to do the same pattern that jeff did Running through rubber feet by the way, we added that as an add-on for the product. Yeah, we stocked them for like 99 Yeah Yeah, yeah, so it's like perfect. It's like making aluminum plates I remember a long time ago actually tried to get something like this made But I was actually talking to an aluminum Stamper and it was just like the setup fee in the manufacturing. It's got it was so expensive It's gonna be like 20 bucks a sheet. That's like nobody's gonna want this but if you just make it as a pcb Um, it was only a couple dollars a piece yeah, and uh So I was like debating what I should put on it and you can see that I It labels each of the grids so that like if you're writing a tutorial you can say like put it in 0 5 or 2 5 or whatever Um electronics by number Electronics by number exactly Um, so I thought that would be handy too. So I'm very excited to see this and uh and do more with it Um, and then the other thing I wanted to show if you can pull up my window. Thank you um, so this is a serial output out of an imx 1060 and what I've got is um That's debug ink that won't usually show up But I've got one of these like dongle things for for like a handheld keyboard Um, and so if I plug it in uh to the dev board, it will show me there and now I can Type on it, um Into circuit python Oh interesting Um, so we're thinking of I've been thinking a lot about like how would you actually? um Edit code kind of from a keyboard that's that's over usb um, although I was just thinking there's a number of stuff that we could actually share with ble as well um, so so ble Hosts kind of would be another thing that we could add is is automatically finding ble keyboards would be cool too um So yeah thinking about that for 9.0 um, and if folks have ideas uh or examples about how to switch between editing and running editing and running I'd love to hear them Because that's the world where we're getting to yeah, another option is uh if you were making your interactions a multiple choice where you're You want to do four different things and you could choose what you wanted to do Do I want to light up an led? Do I want to move a servo? That's another way, but it's always hard to figure out edit versus Display Yeah, and we could do something with like function different function keys to different things. Yeah As well, but I was I was thinking something simple like Escape just toggles you between editing and running and then editing would be like It would run editor.py Like and then you could put whatever editor you wanted Yeah, and so like you could you could have editor.py be whatever you want um And you'd just switch between that you'd run editor.py and then you'd run code.py And switch between the two and that would give you a lot of Freedom to make the editor or whatever you want. Of course, I think we would ship with the default one um But you'd be able to replace it like it would it'd be like the default files on circuit pi all right if folks want to uh toss some ideas your way or Uh, kick the tires on this. How would they how'd they do it? Find me on discord on discord On discord on um There's a there's a menagerie of single serving e-ink devices people who just like to write And they're like I don't want any interconnected and they're they have different modes where it's like I just want to see my screenplay or I want to edit the screenplay Um, should take a look at those or we could steal some good ideas Yeah, that's a good point and then the other thing that I had and and we hit this a little bit when Dan and I were in new york as the pi 400 Yeah, right like the pi 400's got a built-in keyboard It does hgmi out. We already support hgmi out. It's just Just getting the usb in and we could have an all-in-one circuit-piping computer Lotus notes was on a keyboard Yeah, anything it's it's very much like trying to modernize the that like single single task Before the apple 2 you could always dump into an editor and like write Code that then you would run and you there's no windowing system. It was just one right big Disky operating system. All right, this is cool. That's the challenge. How do we modernize it if you have ideas or if you want to uh With jepler is One of the more recent projects you can cobble together your own You know python computer too Yep, and thank you to jeff because I this demo would not have been possible today if I hadn't Borrowed a bunch of code from jeff's cpm He already had though like Convert hid like usb reports into ascii Ah, very nice. Thanks to jeff for Giving me a boost there and and we'll refine that some more to do up arrows and stuff All right, well usb else is very interesting. I mean like there's it unlocks a lot There's a lot of hardware that's only available through um usb and you know one of the things is fast. I remember we did like an um You know in pi about a cellular modem that was a usb modem and it shows up as a cdc port But it's still like it's cheaper to get I'm ready to go usb modem than a module. It's like it's like the the scale is so different You know is a usb and of course we can plug in a usb floppy drive Yeah, I was thinking of usb thumb drives. Yeah, because people like oh, I just want to like log my data Yeah, like read or log data. I like there is it's something it's a demo that we have for usb host on the rp 2040 For sure. Yeah, that's next as well Most of what i'm doing here is built on tiny usb. So any anything that tiny usb supports for usb host will Hopefully just work Okay, all right And uh, it was a great senior. We got a chance to do a little mini Um circuit python convention here in New York Yeah, just see each other after four years if not. Yeah, we're we're starting to see some of our remote see more often now. So, um It uh, it feels good. It's good to be back Yeah, yeah, it was good to travel. Thanks for having me. Okay. We'll see you later Okay, and that is our show for the week this week. Thank you everybody Almost ask an engineer time. We'll see everybody Each week here some 30 p.m. Eastern time on wednesdays next week. Melissa will be hosting and then um, I think we're back The week after I will be doing show and tell Forever, so you don't have to worry about your stuff. There's a couple of people in town They're like, oh, I'm gonna show my chat. Maybe I'm gonna show my um my my project this week I didn't have time or whatever. Don't worry. We're back. We're here every week. Yeah But it'll give you a good deadline. You're like, oh if I get it done, I'll show but that said you should still do it next week Yeah Nothing nothing like a deadline to to get a demo going. Okay. All right. We'll see everybody on ask an engineer. It's a few minutes. Bye. Bye
