 And we're live. Hey, what's up everybody welcome to food show and tell you got your drum beat going. Oh, that's my No, I was gonna. I was gonna drum and I was gonna ask you what are we doing here? Well, you said it. This is a fruit show and tell best place to show off your awesome DIY Tronic 3d printing wearables robot projects. So I'm gonna take a few minutes to go into the community see what everybody's working on We're gonna start to show off with PT Howdy, that's right this week. I'm a guest on the show and tell because we're moving ask an engineer just to this Thursday Sometimes we do it just once in a while. It's not permanent. Don't worry We're gonna be on ask an engineer tomorrow at 8 o'clock. My show and tell is not this TRS 80, which is very cool my show and tell is if you can bring Lady Aida on the screen as well is It does look like you are I'm gonna share my screen a little bit and Show you all What I got here Let's see, can you add me no Pedro? I can do it because I'm admin, but I don't I yeah, I want you Yeah, we all could control the screen. So anyways We have a blog post that ask an engineer is tomorrow and one of the reasons it's gonna be tomorrow is we want to have a special Info section about how do you do a security disclosure in this modern age now? And we recently just did a security disclosure. We didn't one on Friday We had a former team member who accidentally put a github repo public and then as soon as we found out about it deleted It's private no information went out. At least we don't think so and we're super transparent We put up a post we let our customers know But we could have done a better job the way we did it so we sent out emails in addition to getting out the public post and then there's a whole Twitter world and So as we were doing this, I'm just like, you know what we should try to turn this into a learning experience for folks that way when data leaks happen or security disclosures or something so we have a URL a to fruit comm slash March 2022 disclosure and Don't worry folks or your data didn't get out there But we do we do want to tell people because even if it didn't it's good to know that maybe there is a chance So if you look at our security post in our in our previous ones and how we do security It got to the point where we said well, it might be a good idea to share this with the world so we're gonna do a learn guide we're gonna have some stuff we're gonna answer your questions and I Also think that we can help people learn like how do you communicate this in the modern day? So we have a live show. We're very lucky. We have a big social media presence But for maker businesses especially because that's part of it a lot of people come on show and tell and they talk about their maker business If you sell stuff online if you do things with customer data, you've got to be really careful with it You also need to notify people or let people know when something does happen So that's our show until this week not the TRS 80 which is still cool But that's what we're gonna do tomorrow. So come in with your questions And I put this in the chat. You can check out what we've been up to we also put on our press page And that's what I got this week for my show until hi Sweet, thank you guys. It's always being transparent and let us know what's going on. That's right All right, just hear me disappear All right, first up we're gonna take a look at what Jay. This is he's been working on So this I think I've seen yes My Hermes wing shoe design It's a really fun build It works by using a soft switch that I have here on the ankle That when I press it the wing moves up and if I press it again, the wings goes down Very simple bills, but one of my favorite ones thus far just because it looks cool It's something I've been wanting to do for a long time So like I can just I've been wearing them here and there just to test them out there a little bit They're still a prototype. They're not perfect as of yet, but I'm happy what I have so far and it's just fun to play with like Now it looks so cool. My kid would love these I've had so much fun with these is just I want to make them better in the future So I'm definitely gonna come back to this project. These are the prototypes. So we'll call these the mark once Like a progress. What's the micro inside there? I'm using it. It's a bit see believe it or not Okay, sweet. Yeah, and then the touch sensor here is just conductive fabric from ater fruit. So Okay, that way when I hit my heels get a bit of work, but yeah Sweet, so cool. And I think you're writing this. This is one of the learn guides, right? Yeah, it's one of the learn guys the video will be coming out soon I'm hoping and also with the vlog. So once that becomes announced I will post it and share it on my twitter, of course and everyone would know Please check it out. Yes. I will definitely Just let me know because I do want to come back to this build in the future and make it better Because I have so many more ideas, but I can't stay on one bill forever Yeah, yep. So goes you gotta move on to the next thing But hey, the cool thing about that is next time you come back to it You know the the processors that we get smaller and faster and like all the time It'll be fun. I'm excited. I'm excited awesome. Thank you so much for sharing Okay next time Thanks. All right next up we're gonna check in with John And maybe some fun almond breaks. I'm hoping for almond breaks. Hey, maybe maybe we will. Yeah, I've got two things actually I think we'll get to that. Uh, so first I want to show this is a Little web server running on our feather esp 32 s2 with the tft built in so that's I can't open it Easily without a screwdriver right now But I've made a little case for it and there's just a battery lipo battery behind there and I added a switch for enable Which is hilariously large compared to the rest of it, but there you go And this can serve up a web page Either on your network, you can give it credentials and it'll jump on your your network and then you can Get to this with another device. So the web page i'm serving up here is wortl This is the scraped version of the original wortl And one of the nice things is when there's no Network access it'll turn into its own sort of ad hoc network access point And it'll just print on there the name of its own wi-fi and its own password Then you can just log directly onto it So it's a way to kind of carry around a web server that's got, you know, whatever the range is of this You know 20 feet 30 feet. I'm not quite sure But kind of a cool little Gizmo for serving up a web page wherever you go even when the rest of the internet isn't there for you So i'm working on a guide for that. It's just about done We're just gonna add some instructions for people on how to scrape one of the sort of open source clone versions Of wortl as an example, but again, it could be any any file that you want to serve up So that's that guy and then the other one that you alluded to is I had done a audio playback Gizmo using a trellis m4 as a prototype But la more asked me if I could actually make it just a breadboarded thing So this is the one i've come up with I'm doing it on a perma proto just so it stays together a little better for me But it's our kv2040 and i've put eight of our nice little tactile buttons on here A small little rc circuit for filtering the audio and our little stereo 3.5 millimeter Audio output and I just have it plugged into a little amplifier over here I just got the code some version of code running on this right before the show So I don't dare touch these buttons because they'll they'll crash at these last four Are pointing to wave files that didn't actually get onto the drive when I was uploading Right now are just set to Instantly start these different versions of the amen break. So that's just like some cut within it Oh I love that so much The version that i'm gonna work towards is actually what I had shown on the trellis m4 Which is an idea that Todd bought and come up with which is These all are Matched every version of the match and you can also have one one hits They all start playing as soon as the device boots up, but they're all muted and so the buttons just Flip the So circuit python has this really great feature inside of audio io called mixer And it allows you to not worry about Sinking things the wave files just sync because they were edited to edited that way So they're all playing but that means that you can Hold one down play and then come in on perfect time on other ones play one hits when you want so it's a That's what i'm gonna feature in the guide is kind of how how sweet this audio mixer is you can play A ton of I think I had 32 of them playing before On a different wow Just awesome those wave files right off of Memory there's there's very little overhead with waves and so they they play back great And you can use some buttons to hear what's happening with them That'll be a different version of this and maybe I'll have options in there for people who want to play with the different versions of it Dude, I think every song sounds better with almond breaks Every song has them in I don't know how Works, but it somehow works. I forgot we were watching that was like totally not drumming the apple event Like I don't know where that one commercial with the the studio like it just I have a really good, um, I took the uh, funky drummer james brown and and Cut that into like 128 slices and that's a really fun one to use too because there's a lot of vocal samples that you can cut into Oh, man. So that's what i'm working on Oh, so that'll be on the workshop tomorrow. Yeah, I'll probably show this and some other stuff tomorrow and uh, be working on a guide So awesome. We'll be there. We'll be tuning in. Thanks a lot. All right jp. Check me in later Okay, next up. We're gonna check in with jeff Yeah Hello, and boy, I'm glad jp did not ask me whether his idea or todd bot's idea would work because I would have said no It won't go that fast So I'm I'm just super excited to see that project working and that's really cool But anyway, as per usual, I'm going to talk floppy drives So I've got my apple disc two Disassembled and I'm doing some modifications That are going to hopefully let us archive our apple two discs with uh, flexion engine Hardware on the pc. So my addition is this little sensor here Um, which is on a 3d printer riser and attached with some sticky tape that can sense This wheel going around which is the rotation of the disc and you see this little gap in the tape that I added And so basically then we can monitor the speed of the disc and the rotation of the disc and it helps with um Getting the image right onto the computer. And so I've just got some temporary wiring out This is a reversible mod. You just On sort of these little guys nothing is cut and then the signal wire the blue one goes to the prototype board that I've got over here um So yeah, trying to get the data off of kind of those heirloom apple two disc ads that some of us have from you know junior high school or whenever Whenever our lives intersected with those computers, but uh having fun and starting to get some good results And I'll keep showing you as it goes along Awesome. Yeah, so you stop that you're keep coming by. All right printing. Thanks today. Yeah. Yes All right. Thanks, Jeff. All right. Okay next up we're gonna check in with painter dragon Hi there, um been working on an led thing. Um And I'm gonna show us the the face Yeah, this does not photograph. Well, unfortunately, you know video and rgb matrices just don't play nice together Oh, yeah, the worst will be I don't have the actual hardware here. There will be six um square matrices and you form them into a cube and uh It it's basically like if globes were square um, it would be a rotating uh globe on the cube and uh anything that you have as a uv texture map can work with this and Fortunately, like nasa has all these free like planetary textures that they're just free. You can take them um, but also if you google search for unwrapped face you can find uh It's like nightmare fuel. Don't search for that unless you want nightmares. Um, you can find facial texture maps that can also be mapped on a sphere or in this case a cube um, and the reason like this one has has uh, the north and south poles are at the points of the cube And so you get this weird little zigzag sine wave thing going on and then there's a different way where it's just You know flat, uh, you know the top and bottom of the cube are the poles So it'll work either way And it looks rock steady in person, but just on video. Sorry. It's all flickery And uh, so hey, you guys get to photograph that guide. So good luck with uh that part I think it's the it's either 25 or 30 for the shutter speed. I think it's Strange with that one Yep, but yeah, it looks so cool especially the Super buttery in the alias Yeah, you can definitely see that even through the refresh rate going all crazy Well, awesome. Yeah, well, uh, I think we forgot to respond to the way you wanted to do the mapping on the cube and yeah We agree. I think that's the way to go, but we'll we'll respond to the base camp Yeah, I I because it's super persnickety. You gotta line up all the way just right and so it's just like Here's the way it's gonna be, you know, because trying to walk someone through a different layout would just be Dreadful Lay down the law and say here's how your matrices are gonna go Yeah, all right. Cool. We'll keep working on it. Thanks so much for me. Thanks. So Okay, next up we're going to check in with Liz. It is Hello I'm gonna share my screen I've been working on a video synth with a raspberry pi and processing Um, so this is a little demo. I've got going where um, I have this usb mic hooked up to raspberry pi So, uh, basically the number of lines there on the screen Are affected by the volume it's going in Um, and this is just one of the motion demos that comes in with processing and then I have three pots connected to an mcp 30 28, uh, no 30 08 And when I turn the pots It changes the color of the lines with our gmi. So one of them is controlling red Um, so And I think I heard the meaning there's going to be some sort of pizzas and cats Yeah, this is great So it's uh experimental right now, but um, yeah It's actually in some form coming soon We're gonna have uh, uh jp do this little almond break to that. Let's see what images come up Yeah, cool. Thanks, Liz. Good progress. Thanks. Thank you Next up we're going to check in with uh, matt the maker matt you want to get ready. We'll call you in Here we go Hello. Hey, hey in um, 2018. I made this wearable with the pi zero w I um, I rebuilt a new one with the pi zero two. I have the camera and display Camera adapter and the camera cable goes around the back these two cables are hdmi And uh power for the display And then on the back I have an audio hat Connected to a bone conduction transducer And um, I wrote a program um To launch certain, uh Actions with a game pad. So I have one set up over here You can uh This is my launcher or my menu program, which is based on the pie cam api So you can go through the options. This is face and eye detection Uh record video with audio stream to live stream to youtube um retro pie Cody which I have add-ons for youtube and netflix and stuff Um, and then this is the camera program from pie glass v1 that I rewrote To uh accommodate the game pad So what you can do is you can zoom in You can use the d pad to pan up and down left and right Um, you can reset the zoom you can take a picture by holding the button And you can record silent video by holding the uh B button Wow, that's fully featured Well done If you want more information, it's in this month's issue of magpie Sweet, that's excellent. All right, congrats on that. That's yeah, that's so cool. And of course, it's uh Oh, dang it. I forgot what I was gonna say Must have changed that Yeah, it's too cool. His vine was blown. I know like completely blown. That's so cool That's good. Well, it's good to see you again that Yeah, talk back with uh more updates. So cool. I will Check next time And I think that's gonna do for the show until yeah, uh, we normally say don't go anywhere, but Lamar and Phil will be back tomorrow. So I think the same time around 8 p.m. Eastern time So if you guys want to tune in, uh, they'll be in the chat rooms. Um, yeah, we'll be in the discord for a little bit But You know till what do we usually say next time? Uh, take care and good luck with your maker endeavors and until then make a great day See you tomorrow. Bye folks. Thanks. Thanks for coming on Ha ha
