 Hey, hello. Welcome to the show. It is show and tell, but surprise. I'm not LeMore. It's me, JP, I'm guest hosting tonight because Phil and LeMore had some stuff to attend to, but you will be able to see them a little later on Ask an Engineer after this show. So why don't you sit back, relax, and enjoy checking out some projects that people are working on. We have a few people from Adafruit who are going to be showing some stuff they are working on. And if you, a community member, want to come on and show or tell or show and tell, please do. If you want to find how to do that, just head on over to our blog. You will find a blog post with a link or go over to our Discord, which is at adafruit.it slash discord. Look for the live broadcast chat channel. And I've dropped a link in there as well so that you can jump in through your browser. You just need a webcam and a mic connected and you can join in our StreamYard stream and show us what you're up to. So let's see, let's get this thing underway. First off, we have maker Melissa. I'm going to bring on here. If you are ready, here we go. Hey, Melissa. Hi, I am ready. Oh, right. Excellent. So what are you up to? Well, I have this PowerBook 180 that I went ahead and I actually took two broken PowerBook 180s and combined them together. One had like no working screen, the other had no working keyboard and trackball. So now I got a working one. And cool thing about this particular one is I can actually unplug it and it is running on battery here because it actually is like a little aftermarket battery hooked in here. Oh, nice. So were you able to, you said you combined which parts from two to Frankenstein together, one working machine? I combined, well, the display from one and then the keyboard and trackball. And how was, I'm guessing you've probably taken apart and put batteries and logic boards in modern Macs which take about 907 screws. What was the, how friendly was that for tinkering around and plugging stuff in? I think it had like maybe eight screws or something like that to take out. Times of change and probably like ribbon connectors for the display and keyboard, things like that. Yeah, there was a lot of boards that were like socketed into another and then another one socketed into that one. Yeah. Oh, that's really cool. So what OS can you run on that? How late of was that like a system seven kind of machine? I think this one, let's see. I can't remember what I have on here. This one's running system 7.1.1. I don't remember the latest on this but I might go up to like system 7.4 or something like that. Yeah. And what can it, does it have like a token ring plug or what kind of ethernet? Actually, this one has just a modem on it but I actually have a blue SCSI installed on here with a ESP chip. So it could, it's theoretically able to connect to Wi-Fi but I haven't signed up yet. Oh, wow. That is cool. What a neat, what a fun retro project. Can you give us another shot of the screen here? Yeah. That's a beauty. And what year was that one? Do you know when those? I can't remember the exact year but it was early 90s I believe. Yeah. It feels like maybe mid 90s. Yeah, 90, 94 somewhere in that. Awesome. Well, thanks for, thanks for showing that. That's a blast from the past really. And I think those had, those could do some big docks, right? There were some big hulking docks that you could jam them into with like a monitor and keyboard mouse kind of thing. I actually haven't looked into that. Oh, look, you can see if there were docks. I feel like maybe there were for, for a while. It's possible. Yeah. I don't have one, but yeah. All right. Next quest. Awesome. All right. Thanks so much, Melissa. We'll see you next time. Okay. Thanks. All right. Really cool stuff. Next up, we've got Pedro. Hey, Pedro. Hey, John. Where am I? All right. Man, what a retro throwback. Oh my God. Oh, geez. The trackball. Right. So I'm here to show off the three printed cases for the Memento and the wet came up with this super cute little key cat inspired design. So it's compatible with the lanyards that we have. That's what the ears are for. And then if you want to hook this up to a tripod, we have the ability to put it in our three eighth by quarter 20 little threads in there. Really good. And then I came up with the little bear design type one, like a bigger shutter. So like easier for like the kids to push. And then the thing I forgot to talk about was I had a little ring on here so you can have the magnetic like fisheye lenses or this one's a polarizer. Nice. Definitely start adding stuff like that on there. And of course all the usual snap bit. I think this one just requires the, the tripod part. If you don't want it on there, you can attach it with the machine screws. And then doing it up with the Translucent Translucent filament. So we have this one, just regular PLA and then the Pet G once you can see all the cool stuff on the back there. That's cool. But the thing that I want to show off is hopefully go away. Really screen all of the pictures that I captured with it. Because you know what good as a camera project can't show off what it can actually do. So it's a five megapixel one. Did a couple experiments. I'm just shooting right into the sun for this one and see what the lens flare looked like. And it looks pretty good. Kind of nice. Yeah. Yeah. And then handed it off to the kids and took like a little simple one here. So autofocus is really good. Jeff implemented like hold down and the shutter. It'll like autofocus on. I think it's a center point. It's where the focus point is for that. And I was trying like some low light stuff. So like in Tomorrow Land where there's like a little shade when you see like how the ISO would generate like some noise. You can see a little bit of noise generated here. And then for fast shutter some snow. We don't have snow in Florida. So it's clean the yard here with a bunch of snow falling. But I think it's I don't know maybe one or 20 over a thousand or something like that. The shutter speed on it. I was there a way to see what the settings the camera snap. It will if you look in the REPL when you boot it it does give a ton of info and that may be in there. But the yes. Yeah. It's worth looking at the ESP CAM which is what the library is based on to see if you can carry and if you can set. Yeah. That's okay. And just more focusing stuff again fake snow. And then just shooting into like where the multiple exposure or like different exposures where it's like dark and light and seeing how stuff comes up with that. And just you know your sky photo. Nice. Does that look more dark stuff like you know trying to see what the noise level would generate with the ISO being so high. And are you using the stock lens or did you try any of these with that? No. Yeah. I wanted to make sure it was all like what the camera module was picking up. So I didn't use any of that. I think the only filter I think that my son used was so nice little angle of his point of view. How fun. Just more like dark ones to see different levels of the with different exposures out how that comes out. But yeah. It works really good. None of these were like stuck in for processing like in your phone. But when you do do that. Holy crap. The quality like just bump up like the shadows the contrast and a little bit of sharpening a little bit of detail. And wow. It looks phenomenal. Oh that's great. Should have saved one out from here. But I did not. But it looks so good. And you're shooting these at the highest quality. Actually no. When I shot all these I still had just the Arduino one. So I think this is like 1600 by oh yeah. It's not even the highest quality and it looks so good. So I am super impressed with fun. Yeah. So definitely check it out if you want to experiment. You're coming out with a bunch of more projects. Jeff's still working on really cool stuff too. So wow. I am super pumped to get like I don't know getting the trigger to go by like sound or by motion like you know. Yeah. Yeah. Interesting thing is adding your own spin on how it works. Exactly. Yeah. So where to come. Thanks for sharing the cases. Those look great. Grab them already. Take care. All right. Let's see. Next up we have got speaking of jewellers. There's one. Hi. Are we going to wax nostalgic about hypercard because I'd love to talk about some classic hypercard. I used to have this great hypercard deck for like D&D character sheets. Oh. And it is gone. Those floppies. I have no idea where they are but that was the sort of thing I did back in the day. Back on an era of Mac. Yeah. So I brought a little live demo tonight. I've got a memento camera. Whoops. Down here on down here on the down camera and I'm showing off some like kind of real time bitmap effects. So it's cycling through a number of different effects that I've coded up. So we've got blur and sharpen which are effects that kind of look at adjacent pixels in the image and do mathematics on them. And then the rest are working like with individual pixel values and multiplying them or adding them together. So we need to effects like negative or adjust the brightness, lower the contrast. These are just some filters that I came up with based on two building blocks that are in an open pull request. So morph is the one that operates on regions of pixels and does map and mixes the one that you can add channels together or subtract channels and multiply channels. So yeah. It's pretty fast once you like code the low level stuff in C. I forget if I actually showed this last week, but I did a version of this based on micro lab. And unfortunately it was running like one second to do one of these effects. And now it's running 100 times faster. So it was a little disappointing that micro lab didn't bring more performance. But this is this is the direction we're going to go. And so I'm going to continue with this. Yeah, that's some more effects. And so to be clear before you're doing you're displaying one image and then this is a real time effect processing that you're kind of slide through here. So yeah, I loaded one JPEG of a photo that I previously took, scaled down to screen size. And then each time it's working on that screen size image and transforming it into some other image. And that the amount of time it takes due to that step is the time it reports. And then it blitz it out to the display. So yeah, if you're interested in this kind of thing, you can drop by the pull request. I will put the pull request in a link to the pull request in our discord. So you can check that out. But yeah, we will be putting this into the next alpha version probably when it comes out. And this is great. Yeah, I know I was I was looking up someone had a nice interactive convolution kernel web page where you could just type in three by three or the six by six. Yeah, you should send me a link to that. I will. And I think they were the one making the comment that if you look at pretty much all of the original classic Photoshop filters, they're just all built on that. Like every year that's in there, every kind of sharpen that's in there, unsharp mask, they're all just variations on what set of numbers you throw into the convolution kernel, which is wild. Yeah, it's I mean, it's just numbers, right? It's like the the matrix. But yeah, I don't know what else I mean. Also, I want to say those those photos that Pedro was showing are awesome. I live in Nebraska. So you know, you go outside and a you don't want to be there because it's like 20 degrees Fahrenheit and and be it's just snow. So there's not beautiful green things. There's not tourists doing stuff and not having fun. There's no Disney world here. So I really appreciate you getting to see those photos. Yeah, yeah, I was happy to see those those look vibrant and colorful and mm hmm. Yes, they are. Awesome. Well, this is great. Thank you for for revisiting this with a an eye towards speed. It'll be really nice to have these as fast real time. Yeah, it's fun to get in that low levels, low level mode for a while. Really cool. Right. Well, thank you, Jeff. See you later. All right. Next up, we have got Liz. Hey, Liz. Hello. So a couple of weeks ago, I was out on a walk and I found a music on the side of the road and I had wanted one and I'd always resist. I'd see him at Target be like, no, control yourself. So when I was just sitting on the side of the road, I was like, I have to. So when we got home, everything was good, except the battery compartment was completely corroded. It was disgusting. So over break, I cleaned out the battery and everything. And I also printed a new battery door because what I did was I made it USB C and so I used our H USB three to three eight breakout. So it's USB C and because it's just the four alkaline is just five volts. And I just have the two wires are going to the battery compartment there. And I also snipped out all the plastic because it was it was a bad time. But it fits in nicely in the back there. And then I also did your line out hack, which you have the guide on and I had it on pot. And then the other thing that I found to be a little annoying was that it didn't have indicator LED. So I added a LED right there. I'll turn it off so you can see I did a little three of mounts. So it's right there. And then it's a slow change RGB LED. It's a little blown out on the camera. But yeah. And the way that I modeled all up is I actually I brought in the photo that you have of the back in the guide and I was able to bring it to scale. Oh, great. And I was able to get kind of the shape for that. And then the other thing I did was I this is very chunky. And I didn't want to just be like on the floor or like in the way. So I modeled a little holder that press fits into this handle here and trace that out infusion print of it. So now it hangs on the wall and next to the synths and eventually I want to make it either MIDI or CV controlled and add it into my setup. But for now, it's just a nice art piece kind of bringing the room together. Yeah. Yeah. Yeah. Meowsic really brings the room together. That's fantastic. People who don't know the meowsic is not just a friend and a companion, but it is a musical instrument. Do you have it plugged in that we could hear? I do. Let me just turn up the volume tones. Let me know if you can hear it. Yes. Yes. Okay. Great. And you can also do, of course, the meow. That's the stuff right there. Yes. I love it. Now, I know you have a some really cool guitar pedals. And I think that's one of the great reasons to have the line out is now you can send your meowsic meows through crazy reverbs and shimmers and echoes. Yes. I'm very excited about that. And I didn't realize it was polyphonic either. I assumed it was monophonic. Right. Yeah. Is it two note or three note? It's two note. Yes. Which is impressive that they went that far with it. Very cool find. Nice hacks. I love them. A great idea to stop wasting batteries with adding the USB-C. I love that. Yes. Yes. Thank you for your guide for the line out. Yeah, sure. I'm so glad to see it put to use. That's really cool. Yeah. All right. Thanks, Liz. We'll talk to you soon. Have a good one. All right. And last up from the community, we've got Micah. Let me bring Micah on here. Hi, Micah. Hello. So I have a pretty quick show and tell thing. So I've recently gotten into ham radio. And for those who aren't familiar, it's also known as amateur radio. It's just basically people buy or build really powerful or sometimes not powerful radios and use them to talk to people either in their neighborhood or in their local cities or all around the world. So I was going to show my radio and it's called a shack in the hobby. So I'm just going to share my camera. Oops. Sorry. Give me one moment. And it's not working. No, no, hurry. You can, you can trouble shooting. Okay. Working it out. There we go. It's a good sound. That was, I really should have tested this. All right. There we go. There we go. And now I just need to, you know, live demos. They always end up like this. Unless they don't. All right. All right. It's not going to work. So I suppose I can try to... Hey, yeah. That's a good, there we go. All right. So there's my radio. This is an ICOM IC7200. It's a 100 watt output radio, which is not, the legal limit is 1500 watts. But if you do that, then you need to have like a giant tower and then you can't let anyone near it. So I'm avoiding that. Good call. Especially because I am 16 and live with my parents and they would not appreciate having a giant tower in the backyard. So, I mean, it's just a... So this is just all the stuff I've collected. So the tuner is up here. And I guess suppose what I'm sharing is that I've, I do have the license. Someone in chat is saying that I, if I have license, yes, I have, I'm general licensed. Excellent. And it's a lot, it's lots of fun. I'd recommend that anyone who's interested in learning more about anything relating to radio, reach out to their local radio club and say, hey, I'd like to get into Ham Radio, where I start, they're more than happy to help. I just, the local radio club in my area just installed an antenna for me. And it was really awesome. Oh, that's great. So that was going to be my question. Is the antenna external? Yeah, the antenna is in the backyard and it's 30 feet in the air. And it was lots of fun. So that was just, that was basically all I have to say. It's just, you got some more showing that I learned about Ham Radio in the last couple of months and it's really, really fun. And I'd recommend that anyone who's at all interested look into it. Yeah. Oh, that's great. One of my good friends got into it very recently too. And he was telling me that one of the sort of sub-hobbies within the hobby is just collecting communication with people in every state. Oh, yeah. There's all sorts of awards you can get. You can get awards for talking to all 50 states. You can get awards for talking to 100 countries, 200 countries. So fun. That's great. Very exciting. Yeah. Thanks for showing that, Micah. And congrats on getting your license and up and running with your Ham shack there. Very cool. Thank you for having me. Yeah, you bet. See you next time. See you. All right. Very cool. Well, thanks everyone for stopping by. And again, if you're wondering where the chat is, a lot of that is over on our Discord server. So you can go to adafru.it-slash-discord and jump in there for the live broadcast chat channel to see what people are chatting about. We also have some chat going on over in YouTube as well, which I can see here. I'm just checking to see if there's any questions. But someone said, nice rig. Yeah, okay. Well, that is going to do it for our show and tell. I will encourage you to go grab a snack and take a break and then come right on back in about eight minutes for Ask an Engineer with Lady Aida and PT. So come by for that. And then I will see you tomorrow on my workshop show at four o'clock Eastern Time. For A Different Industries, I'm John Park. This has been Show and Tell. See you next time. Bye-bye.
