 Good morning. Thank you for being up early, or for me, I'm early. I'm an engineer, so I like to stay up late. But hopefully I have a really joyful and wonderful presentation I would love to share with you today. So here I am. So I'm a little more freed. I go by Lady Aida. That's my handle for 15 years now. And I'm an engineer. I'm an electrical engineer in particular. And this is me wearing my EFF shirt. And this is my company. And we're actually here in New York, which was really nice because we just had to go up only 20 blocks to get here. And this is my team. So we are in Soho, in Varick, and Spring Street, kind of. And we manufacture open source electronics. So hardware, but we also have firmware and software that goes along with it. And what's really kind of interesting and weird is we actually do the manufacturing in-house. So behind all these wonderful people, you can kind of see some like tubes and stuff. So those are the tubes that go to our manufacturing equipment. So we actually purchased pickin' places and reflow ovens, and all the things that make the electronics you know and love, we have them in our factory. And we have about 100 people. It's a woman owned, me, 100%. Nobody else will take it from me. I keep saying take this company from me. But no, it's my fault, my problem. It's profitable. We don't have loans or VCs or investment or anything. So that means we have a lot of freedom to do what we wanna do and celebrate the people we wanna celebrate and the projects we wanna celebrate. Here are the two people who operate the machines. People love looking at the pictures of the machines. So I like to bring these up. You can see on the left is a stenciler, and then we have two pickin' places. They pick up the components and place them onto circuit boards. And then the thing that says caution, high temperature, is the reflow oven. It's kind of like the bagel toaster in the deli where you put the bagel in, and it falls down. It's exactly like that, but it's 270 degrees centigrade, and it melts metal. And it doesn't taste very good on top of your poppy seed bagel. But in front is Michelle, who really is a huge fan of the Golden Girls, and Vance, who loves Captain America and Superman. And they are running the pickin' places. They're holding the feeders, which kind of look like cyberweapons or something. But they look really serious, but actually they're wonderful people. And these are the people who run the equipment. And what's cool is because I'm right there, like 20 feet away from the equipment, I get to do really fast iteration and fast design and electronics. Like, you know, I have something in my brain. I'm like, okay, I have to get this thing in my brain, and then I'll design it in CAD software, and then I just bring it over to the machine and we make it immediately. But enough about me, what I'm here to talk about is a thing that I do every week, which is I have a show and tell. And this is part of our community outreach. So what I like to do is, you know, make electronics. But I also like to see what people are doing with these electronics. And I think that, you know, a lot of us here are probably engineers or we're at software, we do graphics, and you're kind of in your head a lot, right? You're in your room, and sometimes you're in front of your computer, and you're typing, you're typing, you're typing, and there's an error, and you fix the error, and then you type, and you type, and there's more errors. And then you kind of just do that a lot. And you end up getting really wrapped up in what it is you're doing, but you don't always get to see what happens after it leaves your world, after it's uploaded to, you know, PyPy, or after you've shipped the hardware to someone, or after you've put that video on YouTube. How does it inspire people? What do people do with that information? And what's cool about the show and tell, the project, the show that I'm gonna talk about, is we, every week, invite people from the community back in and say, show us your project. What are you working on? What are you doing? It doesn't have to use our hardware, or software, or firmware. We just wanna know what you're up to. And it's a joyful, exciting, and surprising experience. So this is the show. We broadcast it. Right now we use Google Hangouts. When Google Hangouts goes away, we'll use something else. We've consensuously iterated. It's funny, cause it's true. We've iterated and modified and just had fun. And I've been doing it for eight years. So you're gonna see a wide range of, well, I'm always gonna have pink hair, but I look sometimes a little skinnier. And this is, it's just really neat, cause every week I get to have about six to 10 people who show up from around the world, different backgrounds, different experiences, bringing their communities and their backgrounds and what they do into my world. And I'm better for it. So this is Sally. And Sally is a quilter, and she's really likes making textile art, and she's expanded her textile art into now adding electronics. She comes by the show in town and updates us on her latest project. So this is her showing up a couple of weeks ago. Yeah, I finished this skirt. I'm gonna have to stand on this chair again, see if you can see it. Oh, cool. Oh, neat. Is this skirt? Yep, this is, and the red and green go for one direction and the blue goes in the other, so they cross. Yeah, it's going around. Oh, cool. Yeah, it goes clockwise, I guess. And I'm gonna add another color because I ended up with the front of the skirt unlit all together in long periods of time. But that's basically it, and it... And what's neat about having people come in with, like you can tell by your looking at her, you know, the dresses and coats and skirts you made, she's incredibly technically skilled in creating beautiful 3D textile art and beading. And she has inspired so many people in our community to do more wearables. So we actually see a lot of people doing wearable electronics. This is a project from about a year ago. This is actually only down the street. This is Zach Pozen, who designs like fashion fashion. And... But we hear something really neat. So he was actually teamed up with Maddie Maxie and she designed electronics that went to this beautiful LED gown. And when he did his fashion show, I think it was like winter 2015, they had girls from the New York City schools design the code that went into this dress. So I'll have Maddie talk about it. I think it'll be so exciting to see the girls who've made the animations that are on the dress see what they've done in this beautiful spotlight. Like your hustle goes into these kind of projects and it takes a lot of work and it takes a lot of troubleshooting. And it's wonderful when everyone can stand around and see the fruit of their labor. It was so great to see like our designs on the dress and see how like what we did online could just translate to real life so well. One of the things that I like about the, especially the wearable technology is, you know, New York City has so many people who are fashion designers or work in textiles. And a lot of them don't necessarily think that technology is something that they would integrate into their designs. But this was a perfect mesh of showing code, electronics, soldering, how to stitch conductive thread into a dress and then write the code that runs on the dress, manage the battery power. So, you know, we're seeing wearables come in from tech companies, but we're also seeing like this textile and cosplay art coming from the community. This is my friend, Star. So we went to school together at MIT and she's one of the most creative and awesome people I know. And she loves analog electronics almost as much as I do. No, she loves it more than I do. And she was really inspired by these notebooks called the mini electronics notebooks. I think they used to be sold in Radio Shack and they were written by a person named Forrest Mims. And she loved these circuits because it's how she learned to become an engineer. So a couple months ago, she decided, I wanted to give homage to these circuits that I learned from that were designed in the 70s or the 80s by taking these circuits and turning them into little kits. But instead of just making the kits, she actually took the hand-drawn circuits from the notebooks and transferred them into the circuit. And it takes months actually to get it to look quite right because you have to work within the technology of making PCBs. And so you can see her holding them up. And then on the left, these beautifully, she got a custom Pantone color of the circuit board to match the book. And you can kind of barely see it, but beneath the hand-drawn circuit, which is on the right, you can see these faint lines. She used the copper as a relief to make it look like a line notebook. I mean, she just like went all out on this. And here's a video of her showing it off just as she had finished the project. Yeah, show us one of these. No, it's done. Yeah, if we're moving around there. So here's one now. This circuit is called the Dual LED Flasher. And it's one of the most fun projects that I think a lot of people do sort of very early on. It's got two transistors, two capacitors, four resistors and two LEDs. So that makes it very fast to put together and get results from. And this is the schematic. So you have this drawn out here. You have the schematic drawn out. And that's actually taken from the book. So you can see that that's like a vector of the actual page in the book. This is handwriting. This is handwriting. It's on, yeah, it should be on page 113. Okay, hold on a moment. This is comparing contrasting. So that's actually had the book in front of me. We were like comparing contrasting. And I have another friend of mine, Amanda, who she's wearing a diode costume. And she won't just go with me and we met in chemistry class and we hit it off. And she shows up on the show and tells, she's been one of the first guests actually. So this is, I'm jamming out. This is the video audio sync part. One could say that this photo is rocking. It's also reading. But what's it from like a frequency? It was, what you doing? Oh, hi Edibot. I was just adding some protection to this circuit. Interesting, why does this circuit need protection? Well, a circuit needs to be protected for a couple of reasons. One example is if I were to connect a battery to this incorrectly, then electrical current might flow in the wrong direction and damage some of the components. Oh no, how do you make sure that doesn't happen? You use a diode. So she has this really awesome diode flapper costume. So what's really neat is because I've had so many of my friends from MIT show up, we actually had a parent who watched these shows with his daughter. And a couple of years ago, he emailed us and he said that his daughter asked, do boys do engineering too or only girls? Cause there's only girls on your show. And to this day, when I go to events like Maker Fairs, I get to meet parents and their kids. And these kids have not lived in a world where they haven't seen lots of really cool women doing electronics on this video show that they watch. So this is a puppet show which you can watch on YouTube. It's called Circuit Playground. And this is Edibot who is sort of like our proxy for the Elmo, the young child who's curious about what goes inside of a robot, Edibot's a robot, but doesn't understand what that means. And so Edibot gets to ask questions like, what's a battery and what's a motor? I'm made out of a motor, but what is it? So we get to answer those questions and then at the same time teach and educate. And what's neat is we've been doing this for so long that for eight years, which for me doesn't seem like very long, but in the community is such a long time that we've actually gotten to see people join the show and tell show off their projects in high school, apply to college, become engineers, and then come back after they've graduated. This is someone who came on our show pretty early. Hey guys, so, online there's this all transistor clock that I saw a little while back. And actually I decided I wanted to grow the 47, you know, it's a decade counter chip. I wanted to make a building that with transistors. So I made this about a year ago on a bird war. I never had the heart to take it apart. So I wanted to show it to you for a while. So, there you go. Wow. Oh, cool. That is, that's intense. So wait, there's multiple decade counters or that's? So it's one decade counter. There's a, it's actually being driven by 555 at the bottom. Yeah. Yeah. We can go really quick. For, for extra transitory joy, you could use a basic relaxation oscillator so you don't even have a chip in there. Yeah, actually, well, I built any stable multivibrator for a second version. So that was, that's on a bird war and it's a bit unstable. I work actually as a technician at my school. So we have facilities to etch boards. So it's a, the double sided. Cool. And that's okay. I have to register the, the two sides up. Yeah, it was actually, it was a big pain. And I, there we go. Okay. All right. So now you are, okay, for like six months from now, you can come back with ALU. That's for sure. What are you applying? Well, MIT actually. Oh, great. Well, you should, okay, let's mail in the decade counter. So it's really neat. And I like that we have a place where, you know, I, you know, she built this project a year ago and she kind of had to get a little bit of courage to show it. But if you have a community that has a lot of different people showing projects of all sorts of different complexity, I mean, her project is like more hardcore than something even I would build. But we have people who come in who are like, you can sort of see at the bottom, there are these two kids and they built like a LED throw and they put it in an Easter egg. So they built something that would be considered a very beginner project, but they were so proud of it. You know, because they were only like four or five years old, giving people those positive experiences in a place that's safe to share their projects, even if they're very simple, or maybe they even make mistakes or maybe it doesn't even work out. Actually, you know, sometimes people show off their lives. These are live demos, which is of course terrifying. When people show off their demos, sometimes it doesn't work. And like once in a while, like it blows up just cause like it's a live demo. So we have a special badge called Smokey the Blue Smoke Monster. And so we'll mail them like this cool like badge that they can sew onto their jacket as a reward for like congratulations, you got the blue smoke out of your project. And so even something that might have been considered an embarrassment or failure is a success. So that's kind of, it's always good to figure out ways to like reward people even if something doesn't work out. We're here. Oh, sorry. And so next up is a friend of Adafruit's Micah. And Micah's in the West Coast. And what's really cool about Micah is she's like the most hardcore engineer I've ever met in my entire life. But she really loves beautiful LED art. And she's figured out like, how can I use my incredible technological skills to help other artists make LED art? So here's her and we had her over while we designed, she designed a circuit board to help artists is called Fade Candy. She has really cool names for her projects. And so we built it on the machines and we had her over, she visited New York because she wants to see how you program a board on these pick and place machines that you just saw. We're here at the Adafruit factory in Soho. And with me is Micah, also known as Scanline who's designed the awesome Fade Candy board in high demand, very popular board. Tell me about it. So it kind of is, it's an LED controller. It's something that came out of a bunch of art projects I did with the NeoPixel WS 2011 LEDs. I kind of stumbled upon a way to make them look a little bit better using some new algorithms that give them better color quality, but it was really difficult to use. So this kind of turned into a project where I wanted to take that same quality and kind of make it more accessible to people to make it easy for people to make art projects that just had a lot more room for creativity and less just kind of flunky on off all the time. Like there was actually an art exhibit near Adafruit that was just a gigantic ball and you would like go in it and there was these lights and they were flashing and moving and there was a sound. It was just really cool and it was like your heartbeat or something. It was just a really awesome interactive art exhibit and then I happened to walk by one day while the person was setting it up and asked them, oh, what were you using to control these lights? And they said, oh, we're using this like eight boards called like a Fade Candy. So it was really neat because it was like art making, art making art, you know, it's like the more beautiful version of a Y Combinator. So we put the recursion in the LEDs. So, you know, Micah's gone on to make even more fun projects, but like to this day, almost any LED art you'll see at Burning Man or at a museum or an exhibit or like a music show, almost all of it runs on Fade Candy, which is this open source, hardware and software that she designed. And this is exactly what she wanted and you can see how happy she is. She's like so excited to see her art in the world making more art that she then goes and enjoys. And here's actually, this one doesn't use Fade Candy, but it's the same kind of addressable LED. And this is cool because it's like science. Hi, guys. Okay, so actually I'm gonna move this around. So let me stand up to you guys and get a better picture of what this looks like. Whoa, see that? Yeah. Okay, wait. So this is a project that I've been working on for like about a year now. It's been going through like different prototypes and it's gotten to this point. So basically the point of this is all to kind of help kids get engaged in learning about their bodies. And then this in particular is them learning about anatomy and physiology. So what I have right here is, oh my God, you can see how fast my heart's beating right there, because I'm talking. No, that's okay, it's working, right? Yeah, it's actually working. This is the first like live demo that I've done with it. So I actually have it hooked up onto a, it's something called a Zephyr Bioharness. And it actually, it picks up like your heart rate and your breathing rate and then it displays all that information on the shirt here. So there's a couple different functionalities. That's kind of the live viewing of what's going on inside your body. And I've kind of given it this layering system as well where you can just kind of take stuff off. Whoa. Like that. You can see I've got like labels on it as well. Wow, that's so cool. So you can take, I've got, you can take my lungs off. I can take my heart. What color are you using? I'm using magnets. Oh, okay. Yeah, I'm using magnets. And actually I was watching the Becky's show this afternoon and she was talking about magnets. I was like, oh my God, yeah, I have magnets too. I love magnets, yeah. So I've got magnets there. And then, so I've got this other little nifty thing going on here. So I also wanted the kids to kind of see how the food's moving through their body. So I've got this little snack time button right there. You can see that? Let's make it up. So we click snack time and then see the food going down. And then all of these organs kind of light up to indicate that, you know, there's stuff happening there. And the food goes, travels down there through your small intestine and back up through the large intestine. All right. And actually, I think the liver comes off too. Yeah, the liver comes off as well. So a lot of different funky stuff going on there. Okay, we can be like eye poop, glowing rainbows. Yeah, so I basically have been waiting for like forever to show this off, because I've been working for so long with it. So it's kind of neat to see, you know, she's clearly, you know, she does some electrical engineering and some making, but she also is, you know, a teacher and educator, someone who's interested in biology. So one of my favorite things is when we get people from other disciplines, other sciences coming in and saying, wow, you made this electronic stuff so easy that like even the biologist can use it. This is, this one's kind of interesting. So this is Naomi. And Naomi lives in Shenzhen, China. And what's really interesting about the kind of making she does is she's actually, she lives in the factory of the world. Like everything in your pocket was made in Shenzhen, that's where Foxconn is, that's where Dell makes their stuff, that's where like the HQB markets, that's where all the factories, all the components are sourced. It's an amazing, wonderful place. But it's, despite that, there's a lot of making going on, but it's sometimes difficult for makers in China to get their projects out. I mean, you just need to be like very technologically skilled because you may not be able to use YouTube or you may not be able to use Facebook. So she has to figure out ways to get around the kind of poor internet access that she might have, but she likes to go around the markets and she finds the parts and components that are used for making cell phones and GPS's and she makes her own tools and then kind of shares them back with the community. So it's neat to see a maker from the place where things are made. And this is a time lapse of her making a really cool infinity mirror dress. It's neat, you know, she's got it made. Like she literally goes down the street and can buy components at like the local corner store. So I'm a little jealous. But I think what we're gonna see is more and more of these makers. I mean, like Shenzhen is like the epicenter of electronics. Just like New York used to be like the epicenter of fashion. So I think we're gonna see a lot more makers from China. People who do this for work are people who are learning electronics and then are starting to share more and more. So hopefully we'll see more of that. This is another neat example of someone from a different engineering background using electronics to make their job easier. I thought this was cool. So I'm a structural engineer and a lot of my projects lately have had mass concrete and we have to measure the temperature of the concrete to make sure that it doesn't crack if it's in mass elements. So I'm working for a lot of LRT projects right now and I had to do mockups and it was very, very redundant and it was very, very costly to the site teams. And yeah, so we tried to make a wireless instead of just connecting all these wires into the slab and measuring the temperatures. So I mean, I were trying to wirelessly relay the information to the site teams. So they can immediately know what the temperatures of the slabs are instead of them having to plug in and do the readings. All right, so we'll show you what we made. There's a, there's a trend there. Goes in this box, little waterproof box. And inside of it, there's a feather, Laura. 0.2 millimeter battery. We got a little button over here and a switch over here. And basically, this guy is wired up to thermistors on pieces of cat flag. So then this is a little thermistor. There's no little thermistor here to get the ambient temperature. This guy here would go in a concrete slab. And every 10 minutes, it sends out the temperature from, in this case, three different thermistors hooked up to this transmitter. And there'd be multiple, these little transmitter boxes on the construction site. These are huge construction sites for subway stations and things like that. And the main all transmitter to this box is one of these guys in the construction trailer. And this guy here is another feather Laura and it's also hooked up to a Phona 800. So it gets all the temperature settings and readings from the transmitter. And then it uploads it to the internet. It goes into a little Google Doc that looks something like this. And we get all the temperatures there. We get the battery power there. So everything's running smoothly. We get the decibel between the transmitter and the receivers. We know the signal strength is good. And basically, engineers can check in throughout the day to make sure that the temperatures on the slabs are within limits. Instead of someone going and hooking the computer all day long trying to get readings. So it saves everyone a lot of time and gets them better information. We met at all the stuff that we were from you guys. That's awesome. So this is Erin. So she's really neat. OK, so she's a cosplayer. And she actually also does princess shows. So when you want to have somebody show up as Elsa at a birthday party, she does that. And she also does events and stuff. And she joined a cosplay group. And they have to be barbarians. And it's like a Viking cosplay group. And I don't know how you have so much time that you can not only cosplay, but you have themed cosplay. So this is her group. And she wanted to make a really cool cyber-groom wayfinder. It just looked really cool. So I decided to put it in, because it's such a neat video. You can see the same electronics that are used by a structural engineer to determine whether an underground subway station temperature is going to be sufficient to cure the concrete is the same electronics that someone uses to make an LED room finder for their barbarian cosplay group. So this is like the wide range of experiences that you see. But it's the same skills and the same technologies. Just people have different needs and different backgrounds and different communities that they're using it in. This is Morgan. I think she recently graduated. And she really likes yo-yos. And so she made an LED yo-yo. So quick project here. It's just a 3D print. I saw this on you tweeting or something recently. This is kind of cool. I didn't ruin it. Yeah, it's just a circuit playground, actually two of them. And then I created these cases for it. And it's the yo-yo. So it's a really easy print. Just two prints, a left and a right. And they just have embedded hardwares. Yeah, OK, and hold it. And so you can just press in the hardware while it's warm. It works. I'm not very good at yo-yowing, but hey, it's worth a shot. And then I figure there's all sorts of cool programming things you could do with it. I mean, you could use the accelerometer. You could do stuff with music, with tones. Yeah, I mean, I was planning to use a different camera, but that didn't seem to come through. So we'll see if I can. OK. Oh, yay! I love you as a kid. I don't know why I collected yo-yos, but everybody did. After she finished this project, she actually ended up documenting the project and putting it online. And so we actually had a whole bunch of kids who were into yo-yos. Yo-yos, they literally yo-yo every 10 years. Kids get really into yo-yos. And what I think is neat is, so you see there's cosplay, and science, and biology, but there's people who have hobbies or projects or things that they like to do, like they like to cosplay, for example, or they like to build toys, like to skateboard. And one of the ways that I found is best to get more people in the community and reach more people outside just all you lovely nerds is to have projects that are more fun for people who already do something like that. If you're already skateboarding, you're more likely to do a skateboarding electronics project, and that might be the way you learn to code or you learn to solder than trying to go down to a skate park and just yell at people and say, learn Ohm's Law. Like, you'll really enjoy it, because they probably won't. So that's kind of why we do this. There is an underlying pedagogical reason. I think this is a good way to reach a wide community. So we also see a lot of parents show up. Again, you've been doing this eight years. Sometimes you have to watch these kids grow up and later on, like attend college. But this is Gavin. He made a really cool science fair project with his dad. Gavin. Gavin, hey, man. Hey, man. Yes, you're doing it. We've been working on a project about a new to half a day. We still have a very, very after-paste project that we have in the school. So it happens with a little report and, of course, a science book. It's a feature report. And the material is kind of beautiful and creative. And the box for his, this is the jar. It's a plastic jar with an octopus in it. No, there's a little octopus in there. Yes. But the model talks with some fisherman having to sort through and create a box with, um, you can tell me. You can tell me. It has a very short period. No, this is not a Christmas present. I'll tell you about it later. Now, that is before the effects box. This one you have to have with the tiny ticket. You have to create two-use tickets for you to record and then to play. Yeah. But that's what's headed the way of style. But the last one is kind of super simple. That's cool. So when you press the button, because you can't be there with a science film at the time so that it doesn't voice and it says what the rest it's about. It's super rinky so people know to come over and cut the octopuses and then they work with the model. It actually does a similar form when someone comes out. This is like a museum display. This display itself requires its own science exhibit. And then you have three buttons where you use the messages with quarter-guards. The other one is the button you press this button. You knock the post. You go, I'll take it. OK. You let the post go up and down. You let the post go up and down. You throw the jar with the water. The battery's kind of regretting. This is going to be the first time I've had an octopus on the show. We've had cats, dogs, lizards. We didn't have that. Yeah, they're supposed to have more control if it goes up and down. The battery's going to regret going up and down. How did this do with the science fair? Over and over again, there was a classroom. And I've been running around the classroom for a while. We were released in the entire semester and I loved it. So very cool, Gavin. Are you going to do some more electronics? Well, I'll wrap it up. This was actually a neat project. So this was one of the first times I actually saw electronics that we built a data fruit be widely distributed. So this was a project called Safecast, which, well, they'll explain in the video, but it distributed radiation detection system for people living outside of Fukushima, Japan. So the three of us are just talking, where can we find information? Oh, we can't find radiation data anywhere. And it's not because it's not being published. It's because it doesn't exist. Nobody was paying attention to this stuff. And so that's when we decided that we could start pooling our resources to get equipment, get equipment in people's hands, and go collect some of this data and publish it so that it would at least be something available. Well, looking online, we couldn't get any Geiger counters. Literally within 24 hours, the whole world's supply was sold out. When we realized that we couldn't get the equipment, we decided that the only way to get this done is let's go and build it ourselves. After a couple of months, we realized that it would be much better for volunteers to have something that would be very concise and compact as we really developed the whole system and we were able to use our green arrows and open hardware to fit it into a bento box. And that's how we came up with the bento Geiger system. Once we built one, we taught other people to build many more of them. And that really allowed us to scale it dramatically. This is really neat because it's like citizen science. And I think we're going to need a lot of that these days. So one video I didn't include, but if you remember like the Volkswagen, like diesel gate thing, I don't know any of the people who were at the universities that worked on that, but a year later, I saw one of the big articles and they had a picture of one of their sensor boards and included one of our barometric pressure and temperature sensors. So it was kind of neat. The people who are working on these large citizen science projects, they need access to sensors and technology. And I might make a sensor board and I'm like, oh, I might be useful for people who want to take the temperature outside. But it turns out it's also really good for calibrating your radiation sensor or determining if a multi-billion dollar company is lying to you. And last up, this is my last joyful example. So this is Chris Young, cyborg five. And he actually shows up on the show and tell a lot. And what's really neat is that he's really active in the assistive tech community. And he designs hardware for himself and for others. And he's like a really amazing programmer who also understands the needs of the people in his community. And so he designs like really amazing hardware that interacts and interfaces with, you know, portable technology. Like he uses an iPhone and he uses some of our Bluetooth modules with some custom hardware that he can use to interface and, you know, write code, join our hangouts, control cameras, move around and stuff. And this is his 60th birthday. He said nobody expected him to last a 60, but he's going strong. This is a couple of years ago as well. And this is a video that he, this is around Christmas only a few months ago. This hangouts live on air, what is this Lady Aida? Well, we're live on air here at the Aida Food Factory. It's me, Lady Aida, here at Aida Food in downtown Manhattan. Where we do all of the design, engineering, manufacturing, testing, shipping, the tutorials, the videos, the projects, the stuff that you love from Aida Food. It's all coming to you from here in the factory. And that's where we are. Me, Lady Aida. And of course, Mr. Lady Aida on camera control. But tonight is your time to shine. It's show and tell, which we do every week at 7.30 p.m. You will show off your project to us. Wow. Hey, how are you? Yeah. Hello, Chris. Take this. Hey, guys. Yay. Here's your room 207 of St. Vincent, especially possible in Indianapolis. I want to tell you about my adventure and the rest of the emergency room on December the 12th. There's a lot of different problems. And I had to innovate me and then I put a trick to you. And I couldn't communicate with the doctors and nurses. Most people just, well, I know that or something. But for me, I can't do that. So back on January 20th, on the show and tell, I showed off a little Bluetooth gadget that I built with Aida Food parts. But let's me use my iPhone, just by pushing a couple of buttons. And normally, I just use it in my day-to-day life to play with the phone. But when you communicate with doctors and nurses, it becomes a little more of that. It becomes a real life-saving tool. And so I got a phone and my hand and an email. Thank them for making all these parts available and helped to save my life. And the outcourt of support for me has just been phenomenal, right? I just have been so touched by the response of the bigger community and all the world visions. And I believe in prayers and good visions and good vibes and all sorts of spiritual support helps. And I've been getting a ton of it. And I just wanted to say thank you to everybody for the support. Apparently, I'm not yet ready to be my maker. My maker still has some plans for me. He apparently wants me to do more projects, write more tutorials, and share more open source. So you're not done with me yet. I'm still going to be around. And I have a lot more to contribute. And I just wanted to thank everybody for all the support and say a very, very Christmas and happy holidays. I don't know if it's going to be a great new year with all of you. So what's really neat is as soon as you got better, you wrote this 20-page guide on how he built this Bluetooth device and put all the code into schematics and the methodology and videos on how he built it and how he uses it online. And when he was in the hospital actually, because he can't write and he was intubated so he couldn't speak, so to communicate with his caretakers, he used this Bluetooth gadget, actually a lot like the courting keyboard that Mirabai has here. And he was typing, communicating on the iPad to his doctors. And the doctor actually said, why you should really patent that? You can make a lot of money. And he said, like, fuck that. I'm going to open source it, publish it, and give it to the world, because that's what I do. That's who he is. And so last night he sent me some infrared source code. He uses a lot of infrared technology. And so do a lot of people who do assistive tech. He wrote this really cool library for Arduino that does infrared parsing. He did a really great job. And we're working on more projects together. So I think. This is a demonstration of the iOS accessibility feature known as switch control. A Bluetooth device sends key presses to the iPad or iPhone and allows disabled users to access the device without actually touching the touchscreen. In this demonstration, our Bluetooth device has three switches. One advances the cursor forwards, and the other one selects. And the other one advances the cursor backwards. A long press of any of these switches also enables a different function. So I think as I'm wrapping up here, I think first off, I hope you had a lot of fun watching the joyful, exciting, and surprising things that people are making. But I also hope that as you're developing hardware or software or documenting or videographing or whatever it is that you do in your job and your passion, understand that when you bring it out into the world, people are going to use it in amazing, joyful, and wonderful ways. So we check your community and make it a safe place for them to share back with what they're doing. And do it often because sometimes I get really, really, really frustrated with the hardware I'm working on. But then I watch these videos, and I feel like it's totally worth it. Thank you.
