 Hello everybody and welcome to show and tell. Hey everybody, we're so close to the end of the year, but we're still doing show and tell as usual. It's me, Lady Aida, with me, Mr. Lady Aida. We're here at the Aida Food Factory. It's nice and quiet. Everyone's at home, which is why we're not wearing masks right now. Yeah, we have to do the disclaimer. I know, well, we are keeping very safe. We live together and there's no one around here right now, but everyone's masked up at Aida for everyone's vaccinated. Everyone's boosted, everyone's getting tested, everyone's doing it, but it's now time for the half an hour where we show and share projects together. It's true. Let's kick this off. I think we're gonna go with Jeff. Jeff, what's you got going on over here? Hi there. It's a bird feeder. Well, this is stock photo. This is not my bird feeder, but in the backyard we have an electrified bird feeder because it's a great way to, you know, keep the birds hydrated all winter long. The problem we have- Jeff, our bird's reel. I am not gonna stake out a position on that. Don't at me because- You gotta be careful. We're so careful now. We're just like, you know, there's a bunch of information on both sides. Yeah, yeah, it's really interesting. So I don't know, maybe we'll do some experiments about that as we go along. But anyway, so the heated bird bath, it's supposed to have a thermostat. It's maybe not the greatest thermostat. So the water will just evaporate really quickly. And so I wanted to put apply IoT. So this is kind of the first IoT thing I've done. And these plugs, they have power monitoring and you can put open source software on them called Tasmoda, which of course is on GitHub like all software. And it presents you a little user interface like this. So you can turn it on and off and you can also see instantaneously what the power consumption is. And so I have plugged all of that into Adafruit IO. So this is the ambient temperature actually from National Weather Service. And this is showing the power of the bird bath and this is accumulating it across a day. So now we know how much power it's using. And then it is also turning the power, it's a relay so I can turn it on and off according to the temperature. So if I don't like the thermostat, I can turn it off myself earlier. And Tasmoda is really nice but it didn't play well with Adafruit IO for many of the documentation I could find. So I ended up with a program that's getting a little bit unruly and I just run it every five minutes from a Chrome tab. And because my device didn't work with Adafruit IO out of the box but it did have JSON endpoints. So I could get the data out of its JSON endpoint and then send that right over to Adafruit IO and have it show up in my dashboards that I wanted. So that's where this project is at right now and we haven't seen any birds yet so, you know. What's in the soft as an 80266 or a 32? So I do not know the specs of this Sonoff exactly. I'm like, what's it? Cause it's dead. So it's got four megs of flash. I'm pretty sure it's a 80266, there it is. Okay. Yeah, what's the first step for support? It'll be interesting to see if you could program it with whippersnapper and have it, you know, automatically upload the data. Yeah, that would be nicer. It has MQTT support, but it just insists on sending topics that aren't compatible with Adafruit IO was as far as I could understand what was happening. And I was like, that's fine. I know how to do my own thing with Python running on a standard computer. So maybe we'll be able to optimize the power usage a little bit. Maybe we'll be able to keep the water from evaporating as fast or maybe we'll learn something interesting from the statistics. I don't know which way it'll go, but that's my IoT project. All right, one comment and then three questions. First, thanks for showing how once you have like a common language in this case, Jason, you could do so much with everything and like we built all over a pipe portal to build it. Did I offer that? Yeah, Jason is pretty awesome. So that's neat because that just means like pretty much anything can work with anything. It's a neat clue. So thanks for showing that. And then two questions and then a third question. So with your bird bath, you could potentially turn it up and heat up the birds like maybe even like a little bit too much. Wait, what? No, no, no, I'm just asking. No, no, no, no, I'm just asking. Like how hot could it be for the birds? Like a sauna? No, no, no, no. I suspect the water probably gets to a good 36 or 40 degrees Fahrenheit. So it's enough that in the low humidity and cold temperature, you'll cease water vapor. I'd say steam informally. But no, the thermostat inside of the bird bath is going to be keep it safe for birds, but we just want to like maybe keep it a little cooler. So you want to like shop up some curry, what's celery? No, I'm just gonna go. No, we are having soup for dinner, but it is not, it is not bird soup. And then you could potentially, if the birds are getting out of control, you could make it a little colder and then it breezes over. Or like if there's some squirrels there, you just turn it off. Got it. Right, because who wants the squirrels? And then for the room here and then for the chat. So one of the things that we're trying to think about is, I think machine learning and AI, those words are kind of like busted now and they don't really mean too much of anything. So we're thinking of things that are objects that you're giving intelligence to that you're doing something more. So you're like, your bird bath is now wicked smart. Cause we went to Boston. So it's an idea where anytime you make something better, you just make it wicked smart. So. Okay, I'm not gonna try to say that. No, just think about it. We don't actually talk like that. I know, but just think about it. Just think about it. Like it'd be like, it's a cool bird bath and you'd be like, yeah, I made it wicked smart. Yeah, I mean, I may also need to put googly eyes on it. We'll see. All right, well, thank you so much, Jeff. Happy holidays and more and thank you for making this a fantastic year together. It is a blast. Let's do another one. Yeah, let's keep doing this. Okay. The birds, thank you. We thank you. Thanks, Jeff. Birds are real. All right. Next up will be... Dragons. Hi. Is anything wicked smart? Hey. You have to decide. It's an interactive show and tell. Do you want, do you want a book or do you want a teapot? Teapot. Teapot, okay, you get the teapot. Good, cause that's already up there on the screen. Yes. Even if you're not a computer graphics person, like everybody knows this teapot now, right? It is like, it's like the Wilhelm Scream of computer graphics. And this came about from the University of Utah in the 70s, fellow there, Martin Newell, came up with this model. He actually did the whole tea set, but just like coincidentally, the teapot model was really good for testing different, you know, graphics algorithms, just the combination of shapes and stuff there. And so it just, it snowballed, it became this thing. And so you still see it today. They just stick it everywhere. Cause like I said, it's a running gag, like the Wilhelm Scream. But interesting thing about this is he didn't just make up this shape. It was actually a tea set that he had at home made by Melita, a German company, and they still make them. And I actually have one right here. So I can turn this and translate in real time. I guess- I love the shading. Look at that specular highlight. Wow. It's impressive that it can do this in real time. But so it's a company in Germany, Melita. And if you look on eBay, a Melita with two Ts, eBay or I think even Amazon, you might be able to find them. And it's normally plain white, but I looked on eBay and there was this nice hand-painted one. And I don't remember what the price was on it, but you know, there's that make offer button. And so I made offer 42 and they accepted. Great. So it is a 42 teapot. Yeah, accurate. Yeah. That's so cool. Outstanding. Well, thank you so much, Furby. What do you think of the wicked smart idea for inanimate objects that gain intelligence through IoT or other stuff? What do you think? That's a deep subject. Okay. Okay, I'm ready. I know, this is it. Maybe book next week. Okay. Thank you for bringing your teapot. Thank you. You bet. All right, next. Oh wait, I'm just going to pop over to Jeff for a screen now. Look at this. Jeff. This was at the Seattle Computer History Museum in 2019. And they've got this whole display. I'm zoomed in. I was trying to read the caption, but yeah, they had this whole display of Utah teapots. And it was super cool. Look at this. That's nice. All right. Thank you for bringing the tea. All right. And Pedro, what'd you get going on this week? Well, we have never 3D printed a teapot, have we? We'll have to add that in the 2020. I'll do the global illumination. I know what's called a teapot. I invented one. It looks like you don't need that much support, either. You want all your plants because you made those planters. Yeah, I really could do that. OK, so we'll put a Neopixel in it. So yeah, this week we got this fun acrylic project. It's also got some 3D printed parts. Basically, this is a Neopixel strip. And then these little CNC milled or laser-cut pieces of acrylic. And the idea here is that when you string them together, you can create this little animation. So we're running the LED animation library, running the Chase animation. So you kind of got this little wave going on. You could do all sort of different engravings. So if you want to do some messages, it'd be cool to do some graphics that may be like a walking cycle or maybe a teapot, right? They can kind of spin around. But a lot of folks have been having cool ideas with it. So maybe we'll do something fun with it. But for now, this is kind of what we came up with. It's just got a QT pie inside here. So the QT pie, RP2040, and just a Neopixel strip. So just eight of them. And what makes it work is the little 3D printed bit has these little walls that kind of keep the LEDs isolated so the light doesn't link into each other. So that's kind of like the way you can achieve that effect. But we put together Learn Guide. We got a little fun video, too, to go with it. And yeah, folks, artistic folks want to kind of create some fun animations and some etching and some shapes have at it. So the Learn Guide is up. And yeah, the video is up there, too. So check that out. We're going to be playing that. Just because Phil B is here. Oh, yeah, yeah. Let me crunch the camera. Yeah, shout out to Tobias for releasing this wearable Krumpus mask. It's got the slits at the bottom. And it's kind of like two pieces that you glue together. You got these horns, too. So real nice. He's got his glasses on, too, so you can wear it right over. That's a great print. Yeah, definitely check out. Folks got to take about three days. Mike, bring your printer. But it's all over it. Yeah, for everyone with a 3D printer and you're going to see family, the CDC has recommended this specific mask. Get your mask. Yes, get your mask here. I saw Fauci on TV and he's like, this is the mask, everybody. I don't make the rules. I just work here. OK, tell the horns. You're fair, Tyler. That's much of it. All right, thank you. Next up, we're going to go to Fome Guy. And then we're going to go to Liz. Hello, how are you, Tim? Doing pretty good. How are you? Great now. So I have put together a Pie Portal version of this busy simulator from last week. So right now it's laid out on the Pie Portal and I can push the buttons. I don't know if they're going to come through from all the way over here. But if I pull it back here, I heard it. Yeah, nice. Pull it back by the microphone. It'll play those. So right now I have it just set up as a kind of like a sound board, but I think we'll make it repeat the same way as this. Yeah, that's what I thought was funny. Is it like like you click them all and all of a sudden it's like your computer. Yeah, I think when you're on a phone call and you want to get off the phone call, you could just have the sound board off to the side and you could just be like, oh, hey, and they're like, hey, is everything OK over there? It's like, no, it's fine. It's just like a busy day, meetings and stuff. And so yeah, I have it set up. There'll be the Learn Guy coming out. The code is set up to basically just have a list of these things so you could also swap them out if you want different sounds in there. And it's pretty straightforward after that. So that'll be coming out soon. OK, right on. And you're doing you're filling in for Scott for some of the videos, right? So are you going to be doing a video this week? Deep dive? Yeah, on Friday, on Friday afternoon, I will be. I don't know exactly what time, but I'll definitely put the links up in the in the chat room. And yeah, I usually try to stream if Scott's gone, but it does depend what I got going on on Friday. Thanks. All right. Well, we look forward to it. If we see it, we'll help get the word out. And thanks so much for being part of this Adafrit adventure this year, Tim. Thanks for having fun. Thank you. Good work. I see you have some Slack notifications. Stay busy. All right. Liz, who we just saw in person. Hey, meet Liz. Hey, Liz, how are you? Back to virtual. How are you? You and so long. A couple of days. I know it's been forever. So I've got like a quick kind of break project going on. It's a passive mixer. So basically what that means is you just have, you know, pots that are taking in different inputs and going out one output, but without any op-amps or anything like that. So just to test out to make sure I was thinking of the signal flow properly, I've got one channel going to a main out, and I have a hookup to this MOOC here. And so we're going up there. And so, yeah, I've got some here. Yeah. So I'm going to do this as probably a four by one. So four inputs, one output. And yeah, make the little 3D printed enclosure. It'll be stereo. Good time will be have it by all. Yay, analog pots. Yeah. All right. And thanks for hanging out with us, Liz, for the folks who want to see a photo of our lady Ada and Liz, you can check it out on our socials. We're all messed up in everything. We're all super safe. We're all good. Super safe. Everybody's right on me. Yeah, we're all doing our tours of family visits and more, and Liz happened to be where we were visiting. So we got a chance to hang out in person. So even better than in HD. Yes. Yeah, that was awesome. OK. All right. Well, thank you so much, Liz. And thank you for another epic year together. Keep bopping. Please continue to stay safe. Thanks, you too. Have a good one. Bye. All right. And that's our show in total this week. All right. Thanks, everybody. We're going to be here next week, 7.30 PM Eastern time. And ask an engineer tonight, 8 o'clock. Tomorrow, no JP show. He's out. But Friday, coming up, Tim, will be doing a deep dive probably. Stay tuned to the tweets and more so you can see when that's gone live. And we'll have some of our shows during the week. And then we also have a Descalade 8 on Sunday. So we'll see everybody for an action-packed week. Thank you so much for spending your time with us in between watching The Matrix, I guess. I don't know, we'll see. And not going to go in. Yeah, not going to go in. We'll see everybody in just a few minutes. Thanks, everybody. Bye, everybody. See you next week.
