 Life in New York, it's Ask an Engineer. Hey everybody and welcome to Ask an Engineer. It's me Lady Aida the engineer with me Mr. Lady Aida on camera control broadcasting live from downtown Manhattan that's where we do over kidding and coding and videoing and soldering. Making all the good stuff that you love from Aida Fruit but for the next hour what you're going to see from us is all the latest news and updates from the world of making, hacking and crafting and engineering and more. Yeah maybe. Maybe. Maybe we'll see. Maybe, baby. So we have a baby with maybe a tummy and we have someone who helps us watch Luna during our show but if we have to bounce tonight what we're going to do is we're going to stop the show and we'll record the segments and we'll publish them all on the social media. Usually she's never really on tape so we'll have to take care of that. So if you see that you know I might go into the please stand by graphic which I've only had to use a few times. It's sadly. But yeah but just just so you know if we need to do that that's what we're doing. Rare but happens for y'all or your parents and how it is. So if you need to take care of it that is why the show will be very short or it'll be an hour long. We'll see. All right so let's kick it off. Take it. Yeah tonight's code is Featherstone. It's 10% off on Aida Fruit Start all the way up to 159 p.m. Eastern Time. User Lose It. We'll talk about our live shows including from the desk of Lady Aida with a little bit of great search. Gonna highlight from JP's product pick of the week. Some time travel. Looking around the world. Makers, hackers, artists, engineers. We've got some advanced manufacturing. New York City factory footage. Some 3D printing. We've got Ion MPI this week. It is Analog Devices brought to you by DGKey. We've got some top secret. We've got some new products. We can answer your questions. You can do that on Discord, adafruit.it slash discord or discord.gg slash adafruit. You can go there and that is where you can post your questions throughout the show and we will get to them unless we're not live. You can hang out there at all times and it's an awesome community with a lot of people sharing and more. So as we get started here we do have some freebies. So in addition to the code you get free stuff. Lady Aida what is it? $99 or more. You're gonna get that beautiful golden PCB coaster which will keep your hot drinks away from or your cold drinks away from your desk. Keep your desk nice and safe. No rings. Comes with four little bumpers as well. $149 or more. You get a free KB2040. It's an RP2040 based board that is pro micro pinout compatible. People have used it for keyboard projects but hey it's also a great small mic controller with the RP2040, 8 megabytes of flash, USB type-c, cast-lated pads, tons of GPIO, Stemic UT port, NeoPixels and buttons. Good mic controller to start with. $199 or more. You get free UPS ground shipping in the continental United States. We love UPS ground shipping and we just knew we negotiated so it's a good deal. Check it out. And $299 or more. We're still giving away. Circuit Playgun to express our favorite all-in-one development board. It's round. It's got NeoPixels all around it and buttons and sensors and it can run Arduino or code.org. It has discoveries or make code or circuit Python or even micro Python. It's a great all-in-one developer board for beginners to learn electronics and coding. Okey-dokey. And let's do a little bit of ad-box news. We are almost done with our search, our bat signal for the parts that we've needed all the while. Yeah, well this is one of the... Yeah, we've used this in our ad-box promotions. So we were able to ship a small number at the end of last year in December. Please make sure your account is up to date with your address. Any payment information. We don't charge until we ship and we'll be letting folks know when we're doing a next batch. We had a batch that we wanted to get out by the end of the year. We promised, hey, we should be able to do some amount. So probably can email support at a fruit dot com. Just want to cancel your ad-box or you can also do it in your account. So they understand we have thousands, thousands of people that are buying up who want to get on, who can't because we have a limited number of ad-boxes we're doing. But we are shipping. We'll have our next batch out sometime soon. That's our update, but it is happening. Check out adabox.com has whatever updates. The last update was December 19th. That's when we think, yeah, around December 19th. That's when we did our batch right before the holiday and folks got their ad-boxes. They've been keeping it quiet. Thank you. And then we'll see how it goes with the next round and next round, next round. We should be caught up. This is, you know, years in the making now with the part shortage. And then we'll be back on track. We already have the next ad-box kind of ready to go. Already, yeah. Next one is already happening. Yeah, so, you know, we'll be fun. It just has taken a while. For those of you who are in the biz, this is just how it is with electronics right now when you have thousands of things and on the subscription service. We sent an email today from OpenMV. He's like, after two years, I finally have cameras again. And I'm like, yeah. So everyone's going through this right now. Yeah. And instead of just saying we're not doing adabox over again, we're just like, well, you know, we'll just reach out to the folks, we'll let them know on our shows. We understand if people want to cancel, you know, we don't charge until we ship. So that's a plus. But we totally get it. If you're just like, no, I want to do other things. So no hard feelings. Okay. We do a bunch of live shows. We just show and tell. Thank you so much, Liz, for hosting. Show and tell is every single week, some 30pm. We post a link in Discord for you to show and share your projects, put something on Playgrounds. It's a good place to put your projects and you can share them live on our show. And we post the link you join. And then we do this every week no matter what. It'll be us or someone else from Adafruit. We host a show every week. Join us. From DeskLadyAda, that's on Sunday nights. It's in two parts. LadyAda was in part one from your desk. Okay. I was showing off this power BFF. So I'm designing a couple boards. So one board is a little add on for cutie pies or show boards that allow you to use 12 volt DC power, either from a DC terminal, a DC barrel jack or a terminal block or like both. You can actually have power going in one for the other. And then a buck regulator that will convert up to 20 volts down to five volts, one amp. So it's great if you want to like power your project from, you know, a big battery pack or a barrel connector from a wall, not USB. You want high voltages. I also showed off a design for a board that'll just convert new pixel signal to analog RGB LED, like really big multi amp strips. And then finally I did a preview of it's not out yet. Don't ask Flopsy. Floppy drive board that we started designing last two years ago. And we're finally going to get it out because I can get parts for the power supply. Okay. And then on the great search when you use, did you keep to find the things that you're looking for? You show how you use digikey.com. What did you look for this week on the great search? Well, for the great search, we were talking about this new pixel to analog converter and I needed a three channel inverter that was very small. I didn't want to use like a big dip chip. I wanted to use a tiny little chip. I showed how to use the search on digikey to find TTL logic and which family TTL logic and then what package and how to filter it out from getting thousands of results to like we had like 10 options and I picked one that was in stock and at a good price. Okay. And every single week there's JP's product pick of the week. We have a highlight that we share here, JP, take it away. Airlift Bitsy. It is an Itsy Bitsy Wi-Fi co-processor add-on using the ESP32. You can then inside of CircuitPython or Arduino add some Wi-Fi or Bluetooth capability to your projects. There's my Itsy Bitsy RP2040 and there's my Airlift with the little short header pins on there. You just set those in and set it down. I've specified a Wi-Fi access point SSID and the password. The Itsy Bitsy is going to go and tell the Airlift to jump on to that Wi-Fi and then it goes up to this boardAPI.com every 15 seconds and grabs a new activity to do when you're bored. So right now I said learn woodworking and now it's going to go query that again. So it's fetching Jason from BoardAPI, grabs a new one, hold a video game tournament with some friends. My product pick of the week this week, it is the Airlift Bitsy. That's weird. I guess there's a bunch of blank dead air there. Sorry about that. Luckily we were watching and I think the video edit had some extra sum sum. Anyways, JP's show is on Thursday. You can watch the HP workshop that's tomorrow and then Friday, Deep Dive with Scott Fridays at 2 p.m. Pacific. Scott's back at 5 p.m. Eastern. Do check it out. Time travel. Let's look around the world of makers, hackers, artists, and engineers. I've got a few things to go over. Also even jump in on some questions stuff like that. So there was someone who said, I've never heard of Atabox. What is it? Well, you can go to Atabox.com and check it out. It's a subscription service that we send a box of electronics to you four times a year. It's usually a really interesting, cool, new product that's hard to get in the Infert store because it sells out quickly or it's unique or there is something special. Custom design. Custom design. There's a lot of different things that go into it, but it's also a pre-order because there's a lot of times it's a product that there's only going to be four or five thousand of, so you're going to be the only one to get it. So it's a rare and unique subscription service for people who like to do electronics. I'd say if you're the most advanced electronics person in the world, you probably want to try something else. And if you're a super beginner and you've never done anything with electronics, this also might not be for you. It's a little bit of just a curious person that has a little bit of skills, but isn't someone who's so jaded that it's like, I need to take apart things. It's like an economic centrist. Yeah, exactly. It's someone who's just curious about electronics. I'd say that's where it ends up. There's no age group. It's just basically people are like, oh, this is pretty cool. This is electronics. We have a lot of subscribers. Yeah. So sign up if you want to subscribe because there's no openings right now, but they will be as soon as we ship up. Yeah. Usually some people don't like yearly subscriptions over. I'm not going to renew and then there are lots of them. And if you've never done electronics, this might be the thing to get you started, but I usually suggest not a subscription service on that because you're signing up for something. You start off with something in the website. You get a Circuit Playground Express before you jump in. And then someone was asking, how come things sell out so fast on our website? Yeah. So this goes along with just time travel news. So we put some Raspberry Pi W's and some people get upset when they're like, well, I got the notification. It's sold out already. How could 300 units sell out an hour? Yeah, it does. We used to have 400 units sell out in under three minutes. Yeah. And here's the good news and bad news. The good news is when you order something from Adafruit, we ship it to you. When you check out, it's real. It's because we have it in stock and we're sending it to you. One of the problems with Raspberry Pi purchases across all the sites out there, not ours, most others, is they will take your money and they will not ship you something until they get stock later. That's not great because you think you placed an order, but you just placed an unending back order. So, you know, our support team and Lamar and I, we get, you know, some kind of mean emails because someone will say, well, why don't you take back orders? And that's the reason. They'll also send kind of mean email. Okay. Well, I got a notification, but it's out of stock. And if you look around and feel free to look at, it's easy to figure type Raspberry Pi W or Raspberry Pi 5, look at the other sites that sell it and look at any of the comments online, any social medias or even their own sites that have any type of comments. People are upset because they've ordered their Raspberry Pi back in September and it still hasn't shipped. So, we just don't do back order. That's the trade off. Either, you know, it's like you do back orders, it's like, you have an order, but when you may not get it. And to be fair, 99.99% of people, including everyone watching here is cool and they understand it. They're not upset or anything. It's that like, you know, 1% of folks that, I get it, like life is hard and it's lonely. And sometimes it's sad. And sometimes this is the type of attention that people seek. They, they're just unhappy with everything and they take it out on others. And this is just one of the ways I get it. Other companies and people let them down. And, you know, they're just like screaming into the void. But we're real humans here. So we just try to, it's at a giving up and saying, well, we're not going to sell these things at all or whatever. We just try to explain it in real human terms in our shows and our blog posts and in emails and everything you just say, like, here's, here's what it is. So that's why we do show everybody. It's one of our chances to talk to people. It's like, yeah, it's not, there's no perfect solution to this. So what we've done is like, well, let's sell them when we have them and we'll eventually have enough for you to real time purchase it. But what we don't want to do is take your money or have you have an order from six months ago. Just don't want to do it. And that's how it is. Yeah. So it's a little bit of time trouble. And, you know, like, well, no, not far too short. So in other news, kind of big maker news. This is my beat that I've been writing about for years. Congratulations, Lenore and Wendell and Brie. So Evil Mad Scientist, y'all know them. We've stalked her stuff before. They have lots of art and drawing robots. They have been acquired by Bantam Tools, a lot of people know Brie, former CEO of MakerBot. And Lenore and Wendell are moving to Peekskill. So Peekskill just got an amazing IQ upgrade. Yeah, they just like, imagine like having Evil Mad Scientist move to your town. So they just got like, you know, two of the most brilliant, amazing people moving to a location. They're so creative too. They're in New York. So that's good for our team. So Lenore, Wendell are going to be CTO and COO of Bantam Tools. They're going to be using their smarts to feature and sell their popular drawing and handwriting machines and they'll be able to do a lot of cool things for artists and educators. Yeah, this is great. They let me know. They're just like, hey, because we've been friends probably for like 25 years now. Been a long time. They're like, hey, like, can we talk to you on the phone real quick? And I'm like, yeah, sure. Figured it was something interesting like this. And let me go over to the website. You can go to Evil Mad Scientist Laboratories. You can just type Evil Mad Scientist online and you can try to see what comes up. But it'll be them. And let me just find my browser here. I have a browser, browser, browser, browser, browser, browser, browser, browser, browser. That's not a browser. It's not a browser. Browser. Browser. Yeah. So you can check them out. Bantam Tools is this cool. It was before it was called Other Mill. Yeah. We knew all those folks. So I proposed an idea to them to do like an interview since we used to do a maker business show. But you can check it out. You can check out the things that Bantam makes as well. Oh, what do I want? So in case you're wondering, you know, what we think about this, this is an amazing great home for Lenora Wendell. This is a fantastic treat for all of us who like the type of things that they make. They'll have, my guess is the resources and support to do more of the type of drawing robots and hand running robots I want to do. I really like what Breeze Building and Peak Skill. It's not only like a company, but it's a cause and a business and a mission. So I think it'll be neat to see what happens next. So if we can get them on the shows, we will. I want to do like a 10 questions in 10 minutes type thing, because I know the attention spans are small. But congrats all around to Lenora Wendell. They've been someone we've leaned on for ideas, suggestion, and advice for like open source hardware. Wendell, you know, for the folks who don't know, Wendell and Lenore and Lamar were pretty much responsible for getting what it was. Yeah, it was CADsoft's Eagle CAD and we convinced them to allow XML export and that really unlocked a lot of things for KeyCat later. Yeah, there was a lot of things that goes on in this like, I would love to make a maker's almanac of the things that's happened over the last 20 years. Someone mentioned Open Circuits is a great book co-author. I think it worked on the original open source hardware definition. Yeah. So there's a lot of things going on and the fact that they're moving to New York is really helpful, because I think being in a location together, because there is a factory factory, so congrats all around. That was super cool. Other news that I wanted to talk about is we have an update to our website. We have a works with Whippersnapper that I wanted to show. So if you go back to the browser, so if you go to our website, Adafruit.com, and you search for something, I search for Feather, if you look at the results on the side, now you know if it works with Whippersnapper and these are all the boards. Whippersnapper is our low code, no code, IoT online service free that lets you use electronic circuit boards to do IoT projects. So easy, someone will say you're making it too easy. And we're going to add the sensors too. Right now we're just doing the dev boards that work and again, no code. You just go to the user web browser only and you can set up and do IoT projects instantaneously in minutes, seconds. But we love Whipper because it's great. A lot of people want to do IoT projects, but they're like, I don't want to learn Azure. I don't want to learn AWS. You can do it, but it's hard. So I get started quickly. The way what we do Whippersnapper, the boards that work with it are that Adafruit has, we're able to see with our search. And so you can match those up. So you're like, oh, I want to do low code, no code, easy, super easy, super fast Whippersnapper, IoT projects. You can see what boards work and then purchase them or you can see which ones are compatible. There's other boards that work with all this. It's not from Adafruit. So do check it out. So that's our time travel news for the week. Let's do a little bit of Python R1. We're speaking of Python R1. Okay, lady. To fill it plus community, our newsletter, Adafruit Daily, sign up. We have a completely separate website because we don't want you to be spammed or even think that we spam you. Adafruit.com is where you buy stuff. Learn.adafruit.com is where you learn stuff. And Adafruit Daily is where you subscribe to newsletter. It's where you make show off stuff. Yeah. So the newsletter, you don't have to subscribe. You can even read on the website. It's on GitHub. We got every way. So this week on the newsletter, there's benchmarking Adafruit Metro. I'm seven versus Raspberry Pi, Pico, Lady Aida. This is kind of cool. What is this? Why is this cool? This is cool. Okay. So Circuit Python, look, I'm never going to say Circuit Python is the fastest running code, but it's definitely the fastest way to develop code. It's a lot faster than C or assembly because you're not spending all your time compiling and uploading a year. It's interpreted. It's instantaneously executed. But because there is a slowdown with interpreted code, there always is. A lot of people are like, well, I want to have what's the fastest chip that can run the code because maybe for some application speed is important. And they don't want to write any C code that gets called from Python. So two really popular chipsets is one is the Metro M7. This is a partnership with DigiKey and NXP. Thank you to them for sponsoring the board development. And this is a Metro shaped board that has the RT-1011. And the RT-1011 runs at 500 megahertz. It's a Cortex M7. And so that's this is a beauty chip. It's high frequency and a pretty powerful core with a floating point unit. So it's actually great for Circuit Python. I also have a good amount of RAM. But a lot of people also have a Raspberry Pi Pico and that's a Cortex M0 running about like 130 megahertz. And so people are like, well, how much faster is the M7? It's like, well, it's probably going to be like four times faster, but it actually depends. If you're using the floating point unit, it's going to be even more faster. So here's a really nice benchmark test that shows a lot of different things that you can do each application and how long it takes to do like a repetitive test. And you do this operation 10,000 times. And then it takes a couple seconds and you can compare it. And in general, the M7 is about five to eight times faster on almost everything, which makes sense because it's about four times faster on the speed. And then the chip is a new model chip. So it's going to give you another two or three times. But check it out. And also what I really like is they have a laptop as well. And that's kind of fun. It's just like, well, you know, how much faster is it on a computer? And it's like computers are very, very good. I'm going to interpret it good. Because it's multi core processors. Yeah. And this is like, you know, not a ran or anything, but just like one of the things I noticed. So when folks are like, Hey, like, cool, I'm doing Python on microcontrollers, the idea that that's going to be the most optimized bare metal way to do something is not the point of doing interpretive language is on hardware. It's so you can do things in a development process that's fast as possible. Later on, you're always going to do stuff. If you do Arduino, you're going to write C code later if you do circuit Python, you'll probably do other stuff later, but the chips are fast enough and you'll be able to do a lot more. And then you can optimize later, just like hardware. Sometimes you have a development board that has all the things in the world. But then when you go to manufacturing, it's only the things that are, you know, bare minimum. So there's no intention of like, Hey, this is going to be the fastest thing in the world, but it is pretty fast. So that's kind of cool too. But it's not the intention to be the benchmark winner of every single thing. But it is interesting to check out. But it's still good to know if you're if you're running something on the peak on, you're like, Oh, man, you know, like this, for some reason, you need a faster computation. And you're like, Well, how much faster the M7B this can give you an idea without having to go by hardware. So thank you. It's also a community member did this, we didn't do this. That's very nice. Also, if you're into circuit Python, we do posters for each version, or we try to, we have a new poster vendor, which is cheaper. Yeah. Yeah, yeah, it's, you know, here's one of the things people were doing like, you know, NFTs and digital stuff. We never did. So yeah, we like to do physical posters. It's just hard to find some it's hard to find someone in the US who's doing posters at a reasonable price that we can get tubes from. There was also there's some packaging companies that people don't like. So these the tubes that they come in are from Uline. You're not a fan of that company. There's all sorts of minefields that you have to like navigate around when you do anything. But we have a low cost, lowest cost poster we can get with tubes from a company, all it's all local stuff. So hopefully y'all will enjoy it. And then a little bit of a note, it's circuit Python 2024 time. If you go to ateafruit.com slash circuit Python 2024, you can see our call to the community. What do you want to see in circuit Python stuff that you wanted previous years? Yeah, you can look at the previous years and see what you asked for. And if it got in there, it's getting to the point where it's really advancing. You can do lots of different things. So tell us what's interesting, what you want to see more of. I really like all the screen stuff we're doing. You basically make a full computer. So seeing more easy ways to kind of mix and match like, I've got a circuit Python powered keyboard and a screen and a mouse. And, you know, I got all these different things. Got all these different things. What's the thing that you would like to see? Project examples are a really good idea. And then just look around at the projects that are out there and just be like, Oh, wow, this is like really neat. I'd like to do this. I would see it in this programming language. I like to see it in like circuit Python. That always helps us. Okay. So Advert Daily delivered to you at your inbox every single week. Don't forget. AdvertDaily.com. Okay. I've got some open source hardware news. Oh, it is a news night. Yeah. It's a news night. It's a newsy night. Congratulations. They have flowers is the new open source hardware association board president. Yay. Yeah. The term for like these things are like insider baseball. Like this is what people say. It's like, So I've just been around this forever. So is Lady Aina. So Oshawa is the only open source hardware organization that does certification. There's 2,600 and something open hardware designs. Adafruit has about 700 plus. Sparkfin has about 500 plus. That's the two largest amounts. And then there's thousands of others that make up the most of it, the rest of it, the long tail of open source hardware. And so you could check out Oshawa and you could see the certifications. There's lots of ways to say you're open source. You could say it. You could put a logo on it. Turns out a lot of companies are doing that, but they're really not. But once you publish your files and get it certified, it really is open source hardware. So, you know, whether you agree with how organizations do stuff or should you even participate in things, if you want to do open source hardware and send a signal to your community, it really is open source. This is one of the ways. This is why we donate to the open hardware summit. There is an open hardware summit this year. We just emailed them and said we are going to be a sponsor. So you can check that out. It's 2024.Oshawa.org. It's in Canada. And you'll be able to see lots of folks who do open source hardware. I will tell you why I'm personally excited about Pay of Flowers. Why? Being the Oshawa board president is because Thea runs an open source hardware company in the U.S. and ships electronics and is a business and a cause. And I think that this is just like, it's not criticism, but I think this is really helpful because sometimes the focus on what an organization like Oshawa does is not around businesses. And I get it because they're more into nonprofits and more inclusion efforts. Get it. However, hardware is a business. And to have someone who understands that you have to sell things, their supply chain, and also your advertising something is open source hardware. And that means something. And there's value in the game. Yeah, there's value behind it. So I really like that they in particular has the experience and knows what it's like to be an open source hardware company. I'll give you one example. We're noticing that everyone's using AI tools for their like co-pilot, but people aren't citing them in their publish open source code that they're using these things. So we're like, well, how will we do this? A lot of the chat GPT stuff is trained on the Morse code. So we're like, well, let's just disclose in our readme file that we generated or worked with the open AI chat GPT service for this code. And we link to the session so you can see it exactly. And then we know we credit it and things are going to change. But I think someone like the who's in this world and sees this and also is good about crediting and knows all the things that are going on the 3d printing world. This is a topic that is going to come our way sometime, whether it be software, how do you credit AI code or hardware? When you start to say to something, I want a battery and a screen and I want it to do this, you might get a schematic. How does that get credited? So I think that these new frontiers of where open source hardware is going, whether you like it or not, we need people that are that are knee deep in it. And there is, I think, one of the people that can help lead the way. More than I can't do stuff like this because it would just be too big of a conflict of interest for us. I'm just like, boy, you know, so I write about these things. But obviously, it's on Adafruit and I do all sorts of disclosures. But when there's things that have events and more, and you're kind of speaking for a big community, that's where it's like, I'd really like to see someone who's like, on other boards, who does stuff with the Python software foundation. I like Michael. We hang out. But I'm also glad that he gets a break. It's like it's enough. The former president, the lawyer who's really good about copyright trademark patent, and that's where the certification project was driven by. So this is all really good news. I'm really excited. Thank you. Congratulations. Oshawa, you got a great person. Looking forward to the summit and we're sponsoring. We'll be sending in our check shortly. Okay. Other news in the world of open source hardware. We're up to 600 redesigns. Nice graphic. Yeah. So we have about, you know, about 630 designs are in the shop. I actually thought it was 400, but turns out it's 600 more than I thought. And about 100 of them have been discontinued. There's 700 certifications, but only 630 or so in the store because there's 100 boards got, you know, BMP away from it. One of the reasons we're talking about, you know, hey, we did this many redesigns is because I think a lot of electronic makers just getting back to those talking about people who do and make ship hardware is I think they were really discouraged and frustrated like, well, what are we going to do? And we wanted to show that there is like a little bit of a grind to it, but we did it 600 later. By the way, it's like, I have, you know, the mag tag and the high TFTs. We'll talk about the feather sense and, you know, and then next week, the clue both got revised, but I'm actually like kind of almost pretty much done. You know, the last few are tough because they're like, I really have to do a lot of part swabs, a lot of firmware changes, but it's been a growing. I started this about a year and a half ago. Phil's been very patient with me while they're working on this big project. Yeah. One of the biggest projects. We also had a kid. So there was like, you know, juggling all this stuff in a company. We have a big move we're going to be doing soon. So there's a lot of things going on, but what we wanted to do is kind of the theme of the show instead of just quitting and saying, well, we can't get parts. That's it. We're done. We just did like two a day. We decided to redesign 600 plus products. It's going to be almost 800 altogether. So you can have electronics. And then for us, as there's geopolitical issues, whether you name it, that's going to happen, the planet Earth and the people on it will be able to have more options for, okay, that chip's not available. No problem. That chip's not available. No problem. COVID changed a lot of things. Partridge changed a lot of things. You know, you get beat down, you get up, dust yourself off, and just hit the CAD tools and start your redesigns. Speaking of, we have a bunch of guys. Yeah, people came back. Yeah. What are we going on on learn? Okay. Well, the memento camera guy's been, you know, we'll keep updating it today. Brent added a page on people who want to use platform IO to program the memento camera board. So if you want to do Arduino programming or C programming, the Arduino ID is quite slow compliant because there's just so much code in the Arduino ESP board development package for camera stuff. You can do it, but it takes quite a few minutes. Platform IO is very, very fast. We love it. We've donated to them and it's to support them. And we show how to set up platform IO to do that. So it's for very advanced users, but maybe handy. Erin, you know, this is from a previous Adabox. I play a short video after this. Yeah. She just shows how to actually get spread animation. She's like, we don't know how to do that. I'm like, oh, we just forgot. So a little five by five pixel or six by six pixel animations that you can create on your computer and then download as a sprite sheet and play on your LED graphics. And then now in Pedro, you sent over a while ago, like a cool neopixel fidget toy. And I was like, oh yeah, we should make one. So you the ANO rotary encoder. It's like the iPod wheel. And then a neopixel that swirls around. It's an electronic fidgety toy. And also we've been, you know, with the Memento, we've been updating the camera images with circuit Python guide for like generic camera stuff, how to use filters. And I think that's it for this week. Yep. So I'm going to play this video for Erin and then we'll see you on the other side. Create custom animated graphics for your LED glasses. Make silly eyes that move, wink or wiggle. Let your imagination run wild. Design your animated eyes using Piscoll, a free online sprite sheet generator. Choose your color palette, create your graphics and download them to your computer. Our circuit Python code does the rest. Save the images and code to your ilights controller and you're ready to glow. Tilt your head to cycle through the images using the ilights on board accelerometer. This board has lots of features and sensors so you can go wild. See the full build tutorial on the Adafruit learning system and hit that subscribe button for more fun learning projects. Okay. And then we're just going to roll right into some manufacturing footage made approved in a minute, a New York minute. And that's a little bit of a view of the Adafruit factory. So in 3D printing, we're going to play these videos back to back. It's the fidgety type of thing. Fidgety toy. And then we got a speed up, winter edition. See you on the other side. You can build a portable LED fidget game with Neopixels and circuit Python. This project uses an ANO rotary encoder to move an LED along a 24 Neopixel ring. As you scroll the encoder wheel, the LED moves around the ring. You can press and hold the center button to go into gamer mode where you can play an LED chase game. We think it's a fun way to fidget with Neopixel LEDs and an iPod classic like scroll wheel. All of the electronics are housed in a snap fit 3D printed enclosure. Powered by the Adafruit Feather RP2040, the ANO rotary encoder connects via StemQT, making it easy to build. The code is written in Adafruit's circuit Python using the Neopixel library. With the seesaw library, you can control rotary encoders and buttons over I squared C. In the code, the directional buttons are used to change the color of the LEDs while the center button lights up the whole ring. If you press and hold the center button, it activates the game mode. We think this is an interesting way to interact with Neopixel LEDs using rotary encoders. The enclosure can be 3D printed without any support material using your favorite PLA filament. The Feather RP2040 and ANO rotary encoder breakout are secured with machine screws while the Neopixel ring snap fits into the circular grid. For a full step-by-step tutorial on building this project, be sure to check out the guide on learn.adafruit.com. The 3D printed circular grid isolates each Neopixel, keeping the light inside each segment. A 3D printed diffuser and clear PLA softens the super bright LEDs and snap fits into the grid. A CNC piece of black LED acrylic offers a soft and even glow that looks really nice when fully illuminated. We had a lot of fun putting this project together and hope you're inspired to use CircuitPython for your next electronics project. All right, don't forget on Wednesdays you can tune in to 3D Hangouts with Noe and Pedro, learn how to make all that and more. The longest-running 3D printing show in the world. Let's do a reminder. Code is Feather Sense. There's also all that free stuff. Let's do IonMPI. IonMPI brought to you by Digikey. Thanks Digikey. Analog Devices is what the IonMPI is this week and that's the new product introduction that we're just NPI stands for Lady8o. What is the IonMPI this week? I'm glad you asked. It's a two-parter. It's the Max Ref SD178 camera, which is a long number, but really it's a dev board for the Max 78000, which is a Cortex M4 processor with machine learning convolutional neural network built in. This is a cool all-in-one camera and audio dev board kit. It's got an image sensor camera. It's an OV series. It's got flash LEDs, a bunch of buttons, a headset audio connector for input and output. It's got a microSD card. It's also got a built-in microphone and on the other side it's got a capacitive touch power button and micro USB type C connector that can be used for just like USB or for programming it with the SWD dongle, which comes with it. What this is is a development board for video on the edge processing. Oftentimes you're doing video or image processing. You're using something like a Raspberry Pi or a single board computer if you're not using a desktop, but that uses a lot of power. What if there was a processor that basically had a built-in AI core that made processing audio and video really, really fast and that's what this is. It's a chip that has, sorry, the next one, the Max 78000, which is a special mic controller from Maxim now, Analog Devices. It's a Cortex M4, but it's got also a RISC-5 co-processor, tons of GPIO, tons of memory and this neural network accelerator. So what normally would be like a separate desktop, they call them CUDA graphics devices or you'd have like a coral stick or something that's built into the processor and they can do very fast, as fast as a single board Linux computer, but without the power and of course the instant startup can run off of battery, can go into low sleep mode. All stuff you expect from a mic controller, lower cost, smaller size, instant boot up time without the complexity of having like a full Linux setup. So this is the description of the chip. So on the left it's, you know, it's a powerful, if it's a powerful chip, Cortex M4 with an FPU, running at 100 megahertz, it's got half a mega flash, 120K of RAM. There's also a ton of RAM in the CNN, the accelerator and that's because you could actually load the model and all of your data into RAM. So it like loads instantaneously that you don't have to worry about like caching in flash or like reading enough like external memory, like accused by flash memory, because it's all in RAM and you could execute from within RAM or, you know, update from RAM within one instruction cycle, you get really, really fast updates. You can see, you know, almost a megabyte of data memory just for your image and model. Also all the peripherals you expect, I2S, PWM, I2C, SPI, UI, it's a full Cortex M4, it's got this cool accelerator plugged onto the side. So here's more detail about the convolutional neural network. So, you know, basically, you know, when you're dealing with machine learning models, a lot of mathematics that you have to do, you have to like multiply these tensors together and you convolve them to get data out that then goes to multiple, multiple layers. You know, every layer adds complexity and adds more time, but allows you to do more complicated training and inferences. But the inferences can take a really long time. So, you know, folks who have done AI, you know, if you have it on a desktop without GPU acceleration, you know, it can be 10, 20, even 100 times slower than if you have a specialized piece of hardware that's really, really good at multiplying these big numbers, these big collection of numbers together. And, you know, again, one of the nice things about this is that there was about a megabyte of RAM on the chip specifically so that you can have everything in memory. You know, when I did TensorFlow micro, TensorFlow Live from microtrollers, we tried to do this hack where we would like burn to the flash and then like do execute in place. It's very complicated and kind of nasty and meant that there was this high startup time because we had to like burn the model just quite large into memory because we couldn't into flash memory because we couldn't hold it into RAM. But, you know, that's one of the nice things about this chip is it's designed specifically for that kind of high RAM usage that you need where you have to have a full image in your memory and you're manipulating it and the models in memory so you can load it very quickly. Only tradeoff is like, you know, any AI project, you do have to train the model. Now, it does come with a couple models, and I'll show you when we try to do a demo one. But, you know, depending on what you want to detect visually or audibly, you're going to have to train it. So, you have to collect a lot of data and you have to do the training, you know, in PyTorch and then you can create the model, export it and then program it into the microcontroller at the max 78,000. And the training is not extremely complicated, but it's not trivial, right? You need to have someone who kind of knows what they're doing. You have to have a lot of really good data and you have to have a lot of patience and you have to have fast processor because creating the model is actually quite difficult and takes that difficult like code-wise but complicated computationally. So, you have to do it on desktop computer. You can't do it on the chip. You have to do it separately and then load the model in. But PyTorch is a very popular device tool that's used for taking all this data and kind of smushing it around and figuring out what is the collection of layers you need to apply to the data you've got to be able to train and identify what you want to identify. So, thankfully, ADI has a nice video series that I watched a bunch of it. Taking you step-by-step, how to do training, what kind of data is good, and then how to apply it to the max 78,000, which is their core AI on the edge chip. And then when you program it, you're going to use the built-in programmer that comes with the chip. You plug it into the USB-C. It's kind of cute and witty and then you can select which processor you want to program in because there's actually two processors inside. One is for video and one is for audio. So, that way you could have one processor do both, but in this case, I think they wanted to demonstrate that the speed you can get from having both commands split between the two. And also, each one is pre-wired to the camera or to the I2S input. There's lots of example codes. And here's some models that they have. They have this portrait, cat or dog detection, I showed you that before, face ID, wildlife to detect like deers or cars, outdoors or people. Digital detection, that's kind of the standard handwriting detection. But there's that tutorials on how to take enough data that you can then train it. Also, training models, to be honest, is not. There's tutorials on how to do it. One nice thing is you don't have to use TensorFlow Lite for my controllers. You're because it's the accelerated processor, you can actually use TensorFlow Lite for real. But do be aware, the model has to fit within the amount of RAM that's available on the Mac 7800. There's also a feather that they made for this chip. So, if you want to, once you've got the camera, you've got your prototype developed and you want maybe some other feather compatible hardware to design your own prototypes and product before going to file manufacture. I thought this was a beautiful light blue board. And the dev kit is in stock. It says one in stock, but there's 417 in the factory, which means that they can get it to you within a day or two. So, you can pick one up if you would like to experiment with video or audio recognition. So, I thought we could do a quick demo on the overhead. Now, because it's a live demo, I'm going to say, I hope it works. So, I've got, it's not focused on purpose because it's going to be focused on the screen. But this is Brad Pitt. Just believe me, I'm Brad Pitt. And the demo they've got is, oops, sorry, I have to remember to tilt up. There you go. So, you can see. They can see Brad Pitt. They can see Brad Pitt. Yeah, you can see that they recognize Brad Pitt. Yeah, they can see it. So, it detects like famous people. It's trained on models of the celebrities. So, I'm sorry, it's a camera of a camera. Camera of a camera of a camera. But also, it can detect words. So, if I say up, down. Oh, there you go. Get this closer. Show it. Up, down, left, right. One, two, three. It's pretty good. She's actually pretty good. Compared to. On the edge. On the edge. So, yeah, check out this, Devin, this is taken apart. It's got a battery. It's got these beautiful boards, the video stuff and the audio stuff. A very cute compact little camera kit. Nice work. Yeah. And that is this week's IONMPI. All right, we're going to roll right into new products before we do you don't forget to code as Feather says Lady Edda. Okay, first up, and we have in stock the Grove Feathering. I think we announced this before the end of last year and then people want a holiday. If you have Grove sensors and devices and you want to plug them into something that's a Feather, you're in luck. We know a Feather Wing. They'll make it super easy. There are three ports that can give you analog inputs, a zero, a one, a two, a three, a four, a five, one UART, and then the analog pins can also be digital and then two I squared C ports. Plus, there is a Stem IQT port. So, for any Feather that we've got, you know, we don't necessarily have code for every Grove device, but C does in Arduino. So, as long as you're programming in Arduino or in MicroPython, you're good to go. So, a nice little mechanical adapter for a very popular brand of accessories. So, next up, we have an update to the Surface Transducer. For some reason, couldn't get these during the Partridge either, but now we have one. So, a Surface Transducer, it's like a speaker, but it doesn't have a cone. Instead, you press it up against the surface and it'll turn that flat surface into a speaker. So, we've had these before. So, check out the other demo videos for this product. You'll notice the mechanical looks a little different. It doesn't have wire soldered in. Unfortunately, you'll have to solder your own wires, but it does come with 3M tape on it so you can stick it on to your surface. It's a nice strong 3 watt amplifier. So, a Transducer. Next up, we have an update to the super large breadboard. This is the last board. This is the last board board that's getting premiumized. So, we now get these with really high quality clips. So, they don't like grab stuff and don't let go. They're nice and buttery smooth. Also, a nice black silk screen instead of blue for the negative rail, which I like because it's red and black. It's the colors you expect. Otherwise, there's a gigantic breadboard, but definitely it'll be more useful now that's premium because you can stick big chips in them and dev boards and they're not going to bend the pins when you try to push them in or pull them out. Okay. Next up. Also, an update. This finally is back in stock. This is a really cool multi-voltage power adapter. I just love that on the side. You can select different voltages. So, the big update. It used to be 3, 4.5, 6, 7.5, 9, 12. Now it's 3, 5. Not 4.5, but 5, which honestly is a lot more useful. I need this all the time. Yeah. It's super useful. And it comes with all the plugs, positive and negative. So, this is like, you know, I've got like a label printer that does like 9 volt next center negative. It's like who has one of those kicking around, right? I like that you can flip it around between positive and center. And then just slide on the side, which role did you want? These are quite popular and I'm glad they're back in stock. All right. Also, we've got motors. By request, somebody wanted a double-ended motor. So, this is a bimetal gear motor. So, if you look here, see how some of the gears are metal and some are plastic. The high torque gears are metal. The end of the gear chain is metal, but the beginning of it is plastic. It's a little lighter, less noisy. Plastic is less noisy than metal. But it still gives you that durability of metal for the high torque. It's a 1 to 90 gear ratio. So, it's got a higher torque TT motor. Using a lot of robotics and now it's got two ends. So, you can have some, you know, you have a encoder on one end and a wheel on the other or you have two wheels for some reason. What have you? You're good to go with this bimetal high torque TT motor. Okay, solar panels. Solar panels. So, from Voltaic, they're, you know, they're going to try to get to us, they're bigger panels. But in the meantime, they're having some, you know, they're moving a factory and they, there was, I think, a fire at one or something. I don't know. But it doesn't matter. We've got these beautiful small solar panels. We've got a two-volt, three-watt, a five-volt, three-watt, and I think a five-volt, six-watt. So, these are, sorry, this is, okay, let me read this. This is a, yeah, this is a 0.7-watt, a 0.3-watt. So, it's 0.3, 0.3, and 0.7. They're small panels compared to the quarter you can see, but they're very durable. They've got this, like, nice plastic coating on them. Yeah, they'll take me to the south. Yeah, they're making the highest quality. I have a Voltaic suitcase laptop bag. It still works. I think it's, like, 15, 20 years old. It's awesome, and it's just, like... And they have the highest quality, so, like, these are not cheap solar cells. These are, like, 22% efficiency solar cells. So, the two-volt is not going to work with our light-boat charger board. I do mention that in the part description. It's meant for people who are doing, like, like, power harvesting and stuff, but the two other ones are five or six volt. They will give you a voltage that you can use to charge your battery very slowly, or if you have some electronics that's okay with a slightly higher voltage, maybe there's a, you know, regulator inside, you could power it directly. I just thought that these are nice, like, little solar panels. All right, and then let's start the show tonight. Besides you, Lady Aida, our customers, our team, our community, everyone who shares and tries to uplift us all through knowledge and more is Feather Sense. Wow, but it's big, you know, expectations for this Feather Sense. So, this Feather Sense has been updated. It's back in stock. It's been out of stock for, like, over a year. It's been a little sad, but now we're happy again, because we get to stop this one more time. This is our Feather with an NRF-D2840, really powerful, but also very low power Bluetooth microcontroller that we have Arduino and circuit pythons support for. It's got packed full of sensors and a bunch of them were impossible to get to the part shortage, and we finally got enough of them that we could get this board back in stock. The only chip that had to be changed completely because it's completely discontinued is the Xcelometer gyro, the LSM6DS33, no longer made. So instead, we have the LSM6DS3TR, which is actually a slightly better chip anyways. So we swapped that out. I still got all the other sensors, the magnetometer, the light, color, and proximity, humidity, diametric pressure, temperature, and PDM microphone, all stuck on a board in Feather Format with some Q-Spy memory. It's like a lovely little board for sensing and doing Bluetooth, a little wireless sensor platform for Bluetooth and low power usage. So check it out back in stock. I'm very excited. Alrighty, and that is... No, no, no, no. No. Okay, don't forget to code FeatherSense. We have a couple of questions lined up. You can put them in Discord. If you put them in there, I already got them. We'll get to those in a few moments. Before we get to the questions, we're going to do some top secret. Okay, Ladyita, what is this? We had our question in Discord to stock this. So speaking of LSM6DS series chips, this is the LSM6DS-V, which is used for VR and OIS, like optical image sensor stabilization. It has built-in sensor fusion. It has the same footprint as our LSM6DS-032 or whatever, or DSOX. So I was like, oh, great, just swap the chip, and I'm going to make a prototype and try it out, see how this chip goes. I also made a board that I need a lot. It's something that takes NeoPixel signal in and drives a powerful LED or analog LED strip. So the NeoPixels, they're bright, but sometimes you have a gigantic strip that takes RGB analog common anode, or you have a three-watt LED. This is a little board that has WS2011. Takes that signal, inverts it, flips it, turns upside down, drives it through some powerful n-channel FETs, output to a terminal block. Yeah, and you're just like, oh, this is just watching Naskin engineer, and this is like, wait, what's this? This is a really cool top secret. Yeah, this is like, this is folk two years ago I started this, and I couldn't get the power regulator chips, and I was like designing and redesigning and redesigning. I couldn't take it anymore. I shelved it and said, I'm going to get back to this when I can get components again. So this is a floppy disk-shaped floppy controller. So you can, you can say flop, and it's got a little floppy bunny, some artwork that you and Bruce designed that I found on the base camp. I just slapped it on there. Yeah, this is a floppy disk controller, an open-source one, and it's going to help a lot of people do a lot of fun archive work. Yes, because here's the thing, I go and visit my parents and they've got all these boxes of floppy disks, and I wanted to like a standalone floppy disk reader that would be able to dump the floppy disks. So we wanted to make it easy. There's like really intense communities around archiving stuff that kind of chases people out and we're like, well, let's make something that can bring everyone together in some way because there's like not open source, open source. So it's going to be all open source. Everybody will be able to make it share the hacks and mods with it. There won't be anything like weird. They have to like buy NDA stuff just to copy a floppy. So anyways, I want to copy some floppy. Yeah. Anyway, so it's a lot of stuff. I tried to bet a little bit on the disk reader. This is just the first prototype, but now you see it. You know, we started with the floppy feather wing and then this was going to be coming out right afterwards and then make it. So, you know, there is an expiration on floppies. They eventually will get harder and harder to copy them. So we also want to make a tool for people to get all the smarts and all the weird things that were developed over the years off those devices. We check out the Prince Floppy. It's one of the things that we wanted to do. We imaged the Prince Floppy with the font on it. Just type Prince Floppy Adafrit. You'll see some of the things we did. Let's stop the grid. All right. What's going on? Okay, rolling into questions right away. Yeah, we're going to get in and get out. How do you create a driver to control Neapixel on other processors that you didn't create like an IMX8M? How can I modularize the pulses for Neapixel on other Linux based processors do not have a library with PWM? It's very hard and that's why I created the Stema iSquared C to Neopixel converter board because this comes up a lot. In fact, the description, it says. I was going to say this sounds like an industry plant. We have a thing that plugs in that does this. Yeah, it's iSquared C to Neopixel can drive like I think 250 Neopixels. It's not super fast because it goes over iSquared C. But iSquared C is a lot more universal. And if you're using Blinka or whatever iSquared C, you know, library that comes with your mic controller, you just basically tell it how long the strip is and you write the data and then you tell it pulse the data out and then it writes it. And I have some example code in Arduino and in circuit Python that people can get started with. Adafruit, we have a thing that plugs into a thing that does the thing. Okay, I just want to know if it's possible to overwrite an FM frequency. You did some jamming. Yes, but not legally. You can get FM transmitters and amplify them and you can do it. You know, but you have to overpower FM and in particular, you know, that you have to lock in on the stereo signal. And so it's a little tougher than AM. Yeah, remember there's things that would plug into the top of an iPod that would broadcast your sound and you would tune into it on your car radio? Yeah, after the floppy, I should do like a cassette reading thing. This is just a compliment. I love how much redesigns have stomach connectors built in making the I3C so much easier to hit the ground running with the project and makes iteration faster. That's the goal. Would Adafruit's USB isolator serve as a temporary solution for keeping my hand radio from disconnecting from my laptop when I tune in a transmit? Maybe. It depends on what's actually happening. If it's affecting the USB, it probably won't because you'll just interrupt it earlier. Maybe get a USB cable check. You can shield it. Maybe your USB cable isn't shielded. This is tough. It's really tough to know exactly what's going on. You can try creating a ground shield around your USB cable, like by hand with some tin foil and a ground strip. That's the first thing I would recommend, but it's tough to know exactly like how it's disconnecting, what's causing it. Can the transducer also work as a microphone? No, not really. It's very heavy. For Adafruit underscore display, underscore shapes versus Victor IO, when would you choose each library of drawing one circle or line versus a thousand circles? That's a good question. This is actually a great one for the help of Circuit 5 on Discord. I'm going to tell you, ask FOMI guy because he knows this graph stuff. I wouldn't tell you the long thing. You could probably tune into Deep Dive with Scott and ask this Friday, 2 p.m. Pacific, 5 p.m. Eastern. Scott would probably be able to tell you as well, but help with Circuit Python channel with Discord. I'll see when more could probably guess, but that's the right place to go. Ed, if I'm allowed to question you, is learning spice for schematic simulation worth it, or is it better just to order mail PCBs and see if they work? It depends on what you're doing. If you are working on really intense analog RF stuff, simulation I think definitely is going to help you because you're dealing with analog circuitry and you want to get the filters where you're going to tweak inductors and capacitors and resistors and maybe that's easier than doing a lot of linear equation solutions. For digital circuits, I don't know, unless it's just pure TTL logic, but a lot of people are doing stuff with micro controllers these days and you're not going to simulate that. So I think for a filter, I think using spice could be useful just if you're like, hey, I want to get the bony plot out. I would also just build it. If it's less than 10 megahertz, it's built on a breadboard. Okay. And then this one's really easy. How do I get involved with making learn guides? Who should I reach out to? No one. Guess what? We have playground now. You can do it without us. You don't need us. You don't need us. We've made this so you can do it. So if you go to learn.atorfruit.com and then click Playground, and you check it out. Look at all these guides. Look at these. Look at these. Look at these. Look at these. Look at these. Look at these. Look at these. Guides. Right here on guide. Right here on guide. Yeah. And then this is, we have a nice little graphic. We have all these things. And then these are all that you can do this IKEA thing. For Finnegan. Yeah. There's plenty of like fun projects to do. Look at all this. You can make a grill. Yeah. We have like 300 plus guides already that you, the community is doing. And we also made this so there's no ads. You don't have to log in to view all of the steps and everything. We'll sell your info. We don't track. This is had blocked, by the way. There's really, this is what it looks like. Yeah. You know, it's weird going to our websites and the little ad trackers is like, Hey, something wrong with your next one. Someone's asking about round LCDs. Yeah. Check out our site. We have some of those. And then question, what are you excited for 2024? New chips, et cetera. Yes, there's some new chips. Can't talk about. It's going to be great. Yeah. I'm most excited about these boxes. Yeah. I'm excited to be done with what we did. We designed revisions that was and I'm really glad I'm done. Yeah. It's a, it's a builder year because we can get all the things we need together. And I'd say the most exciting thing is we have a chance, we have a chance together to show the technology world. If you do hardware, open source software and open source hardware, I think we can set a really good example of what it's like to have a group of people that are motivated by, you can run a business, but we're also motivated by something bigger than all of us, which is sharing information. It doesn't make sense to redesign a power supply version. It doesn't make sense to redesign everything over and over again. Open source hardware and open source software really accelerates humans. The analogy sometimes that I say is like, yeah, I guess you could like invent every recipe from scratch, but you can also get a cookbook and get the knowledge of other people that kind of learn how to cook the thing the right way and temperature and find the right ingredients and all that. And you get to become a better cook. But the best part about cooking just isn't the doing it and all the gadgets and all the things is you get to share a meal with people and that kind of is the thing that happens with open source hardware and software is in the end you get to share it. And that's the thing that we have a shot. And I think we have to set a good example because let me tell you something folks, it's shitty out there. It's terrible. It's never been worse for people who do technology in so many different ways, but that's an opportunity to make it better or show a different path. And even some of the people that I really admire, they're cranky, they're burnt out, they're mean, they hate themselves. No, they hate themselves. They hate everyone. They hate computers every day. I hate computers. I'm so sorry that it did to you, but there is another way. There's another way. And the other way is like, there are good things that are going on with technology. And I think the people in this community are the ones that are going to show by example. It's going to be a weird year for sure. This is one of the, I think, more positive things you can do with technology and your smarts. So thanks for joining us. That's what I'm looking for because we have a chance. Like, that's what I'm really, the thing I'm looking forward to is we have a shot. We have a shot. How often do you get this where you have a shot to bring people together to make and share something? Not that many times or chances. So last one will be, oh, there's a follow. How do you recommend creating this driver, PDV and duty cycle modulation, if yes, based on pulse duration? They're sure I ask great technical questions. I don't, I don't know your processor. I would really not to just, I mean, you can look at other designs and do it, but please do not keep asking. Okay. Any more ESP32 product coming down the line. So we have the ESP32 itsy bitsy. Okay. It showed a preview of it. Alrighty. And with that, I think we're going to call it those relevant questions. Thank you everybody. Them's are questions. That was our show for tonight. Don't forget to code is feather sense. There's that free stuff. Don't forget to check itabox.com for the updates as we're shipping more boxes. Yeah, address. And we thank you very much. This has been an Adafruit production. We will see everybody next week. Here is your moment of Xenar. Bye, everybody.
