 Life from 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 and audio mixing. We're here at the Aidaford factory in downtown Manhattan, thank you Mr. Lady Aida, where we manufacture, test, ship, code, video, and tutorialize, document, photograph and more, all the electronic goodies that you look to use in your projects. Next hour we're going to be just kicking off news in space, products, electronics, updates, shortages, catch-and-tunes. We've got a jam-packed show, the beginning of the show, that was a little video from when we went to Manhattan Henge, which was earlier this week, that's when the sun happens to line up exactly with the grid in Manhattan and you can see the sunset go through all the buildings. And then tonight is a Supermoon, I'll be talking about that because it's the code. And then we'll talk about some other celestial events. There's a lot going on today in particular. So on tonight's show the code is Supermoon, 10% off in the Aidaford store, all the way up to 11.59pm tonight. Go outside, look at a Supermoon, there's only a couple of them in the year and this is one of them tonight, it'll be a little bit bigger than usual. Live series shows, we'll talk about some of the live events and more that we do, including tonight's show and tell. Talk about some of the folks that were on show and tell. It was a parade of talent, time travel look around in the world of makers, hackers, artists, engineers, and more, including a bunch of stuff that's been going on in the news this week. Chip shortage this week, it's ST. We'll be talking about some chips that we ordered and we really, really need. And hopefully, when we make our plea, they'll send us some chips. We'll do from the mailbag, read your letters to us. Some help wanted from the jobs board, jobs.adaford.com. We'll show some factory footage from Aidaford, the advanced manufacturing company made right here in New York City. We got some 3D printing, we've got IonMPI brought to you by Digikey. This week is a product from Analog Devices. We'll do some new products and we have a super fun top secret, so tune in to that. We're going to answer your questions. We do that over on Discord, adafruit.it slash discord. Please put the questions in Discord. That's the only place we can see them because we're streaming on multiple places. Yes. Please, please, adafruit.it slash discord. It's free. Join all 34,000 of us. All that and more on, you guessed it, Ask an Engineer. Is this graphic change a little bit? About a year ago. But it did change. I thought it was animated. Sometimes it was. So we are slowly getting some of the parts that we need in stock. So that means we got to update our freebies. Yay, we're back. So what are we doing? OK, $99 more. We've still got the Permaproto half-sized breadboard. As always, people love it. It's a great way to take your sort of less breadboard projects and make them permanent. $149 or more, we've added that KB2040, a beautiful pink PCB, featuring the RP2040 that people love this board and chip. It's got Stemic UT connector. It's cast-alated. And now it even works with QMK. They've recently added support so you can actually use it in keyboards. It's got lots of memory and USB-C. Free shipping at $199 or more, UPS Ground, and back. It's the Circuit Playground Express. I know you missed it. We did not have enough SAMD21s to keep these in stock and also get them to schools. So we prioritized getting them to students in schools. But now we have enough that we can give them away back as freebies. So hopefully for the next couple of months, we will have that still here when you order from the food shop. OK, and don't forget, if you're trying to get something that has supply issues like the Raspberry Pi 4, 1 gig too big, 4 gig, 8 gig, and other items, please make sure you sign up for an account on Adafruit.com, verify your email, and do two-factor authentication. You should do that with all of your stuff. I think something like one out of every company has some type of cyber attack going on. And two-factor authentication is just one extra layer that you can do to keep yourself secure. You probably don't have to worry about it as much on Adafruit site. But if you do this for one site, you might do it for other ones. So it's good security practices. So please, please, please do this. It's also the only way that we allow purchases for that particular product lineup. So please do that. OK. Also want to mention, I'll put the code in the chat, but it's Supermoon. And here's a Supermoon. OK. It's super. We do a bunch of live shows. This is one of them. So, yeah, we're going to do just a quick mention. Someone mentioned in chat, we probably don't need to do an in-depth overview of show and tell. So we actually. Yeah, we actually. We used to. Yeah, we used to because not everyone would see each show. So basically. No, you're short. So basically we say, please watch show and tell. I think one of the projects, or folks that you might want to check out this week, you get a glimpse of the DigiKey parade that they're doing. Well, it's not. It's a thief of a false parade, but DigiKey's in it. I always think it's neat when companies are civic-minded and they do stuff with their local cities and more. You can see some of the sight and sounds. Also, Jay's visiting DigiKey so you can see Jay there. So thanks, Kevin, for coming by and showing that off. And then we have a lot of neat wireless stuff going on with CircuitPython and ESP32s and ESP32S2s. Yes. So check that out. Live demos. Yeah. On Sundays, we just, Desk of Lady Eta. It's usually in two parts. What was this week's Desk of Lady Eta? This week's Desk of Lady Eta, I showed off proto PCBs that I got. We did an INFPI. We missed one because we had, we were out of town and so we didn't do a Desk of Lady Eta. Sorry, we didn't do a Ask Engineer. And so we were behind on one NPI, so I did that live. Also showed my workflow and I showed off a new Stem Abort with the MMC5603. It's a low-cost magnetometer. I tend to use the LIS-3MDL magnetometer, but the prices really went up quite a bit two, three times. And so I was looking for an alternative, which was low cost and found one and got the driver working in Arduino and CircuitPython. So I just talked a little bit about how I do that. All right. And then we use your powers of engineering, define stuff on the DigiKey site. We call that segment, the Great Search. What was the Great Search this week? Okay, the Great Search this week was actually, someone posted in the forums, they wanted to find how to match the look of a connector on the DigiKey site. So you know what it looks like and you know the pitch, but you don't know what the part number is and a lot of connectors are kind of called the same thing. These days are like, it's a Molex or it's a Berg connector. How do you actually find the actual connector? So I go through and we show off the beta DigiKey site as well, which is nice and rounded. And I find how to identify the connector. I think I got it. Okay, cool. Don't forget to tune into JP's product pick of the week. We do that every single Tuesday. You can watch the highlight on YouTube or you can tune in live. We do, I think one of the only, certainly in the electronic world, but one of the only shows where there is a live broadcast from inside the product page and the discounts automatically applied. So check that out. And then Thursday, tomorrow, check out JP's workshop where you can learn all the latest and greatest JP's working on a very cool, I'm gonna call it a walk. Walkman? It's called Walkman. Walk person, walk entity. It's a really neat retro project that uses kind of all the latest and greatest with the retro form factor and then check out the Circuit Python Parsec with JP where you can learn a lot about Circuit Python and how many of his projects work. And then on Fridays, join Tim from the guy for Deep Dive with Tim, 2 p.m. Pacific, 5 p.m. Eastern where you can learn about all the innards of... That's a graphic stuff. I think he's working on, I assigned him a project to take one of those Game and Watch, like Nintendo games and port it to Circuit Python. So I think he's working on that. I think he's working on the octopus game. Yeah, I have one of the original ones and what is it like 30, 40 years ago now? And what's neat is you have the ability to do all this in like Python and Circuit Python so you can make your own. Yeah. Okay. Time travel. Lots of time travel in this week. Lots of news this week. First up, let's talk about this moon. Oh yeah, well... I'm just kidding. Yeah, it's a super moon. So go outside tonight and I think if you go online, you can see the comparisons of the size of the moon tonight is a little bit bigger and that's why our code is super moon depending on what spiritual things you do. This is a big day in certain parts of the world. Buddha was doing stuff. All sorts of things happened to fall on this day in particular. I do have a reminder next month is Circuit Python Day. So I'll talk a little bit about this in our Python and Hammer section but mark it on calendar, August 19th, it's a Friday. It's a company holiday here at Adafruit but worth doing a bunch of stuff. We're gonna have all day events online and you'll be able to do stuff, especially show and tell. So if you have Circuit Python projects, come on by and we'll have you on and we'll show and share some cool projects. We're up to Circuit Python 8 and this is I think our fourth or fifth Circuit Python day that we're doing. Yes, and we've got so much cool stuff coming in Circuit Python 8 and we'll have some demos. Scott is going to be going on leave right after he'll be back but we'll have a mega demo. And we have a chip shortage video tonight and that always brings us back to hey, when is Adabox gonna ship? Well, we wanted to ship in April. The chip shortage made us think that maybe we'd ship in spring. Now it looks like it's summer. It's summer. So we're gonna be hopefully shipping Adabox soon. We continue to get all the things together for the latest one. Don't worry, we don't charge your card until we ship Adabox but it looks like summertime is when the latest Adabox shipping we actually are starting to get parts in like you guys mentioned earlier the Circuit Playground Express is back in stock. Yeah. We got a couple sensors in. It's happening. So it's some things are trickling in. It's like running through molasses sometimes but we're still running. Next up, we posted this up on our site and I just wanted to mention this. So a lot of these things never work out but we went ahead and got the word out and signed our names on it. There is a bill to provide incentives for domestic production of printed circuit boards and for other purposes in the USA. So we signed up for this. We'll try to keep everyone in. Like the Osh Park bill. Yeah, the Osh Park, that'd be kind of cool. It's purple. The purple PCB bill. It's hard to cut through the news right now because there's so much stuff going on and it's mostly polarized and you really don't hear a lot about manufacturing in the US. You basically hear a lot of factions arguing with each other. So we'll continue to be as focused as we can on the things that could help all of our industries that we're in. I have a tendency to think of everyone did science and engineering and shared things. Maybe we'd have less problems in general. But anyways, we don't have, and I say we as a country in the US, we don't have as much domestic printed circuit board production as we could. And so that's an opportunity and a lot of people are like, boy it would be great to manufacture more stuff in the USA. Well, it's kind of hard when most of the PCBs are just not made here. So, you know, there's some PCB manufacturing in the US but this would incentivize it and it would help make it happen. You know, we've all seen a lot of the false starts for factories getting built like Foxconn was gonna do it like 10 times over. So we'll see. So check it out, it's on our blog. The deadline to sign is over but this is just the start of many that will try to help get the word out as they come in. So more time travel. We're gonna go back a few billion years. Boy. You know, we normally, so we don't really cover a lot of news events. It's very focused on electronics and art and science and education and like maybe we go to an event or something. Hair dye. Hair dye. But it's hard to ignore what happened this week with the web telescope. The first image dropped, they did a preview and then they released a few others and I wanna take a look at this. I think this is one of the times where like everyone kind of stopped and looked in wonder for a while and said, wow, this is like, we're part of this. And if you look, you can see the lensing around certain locations. And it just seems to fulfill a lot of the theories that people knew about and just lots of confirmation and just like amazing. So this is where a galaxy's light bent around either a star or a black hole or a giant mass of object. It's an unending galaxy. This is like if you were to hold your hand out and have a grain of sand on your finger, this is what it could see just behind that. And that's how many billions and billions of galaxies are out there. And the neat thing and the really weird thing that'll kind of break your brain is all the stuff that exploded from the stars collapsing eventually collated solidified and right now it's you. It's you looking at this. We are made out of space stuff. And it's space stuff that's aware that it's space stuff. So all the stuff that came out of this and all the stuff that continues to come out of this is us and we are it. And it really makes you either feel completely alone or completely connected. And it's just a reminder of how wondrous and how much splendor there is out there. And maybe we could all think about that and maybe some of the bigger problems would go away when we see how special and unique we are, but also how connected we are with all these things. And we are the things that know that it's things and that's the weirdest part. I think all that stuff out there is now aware that it's stuff out there. Anywho, so some other photos dropped. We'll post them up on the blog. This is a neat Nebula. If you look in really close, it's a dual star. A lot of systems are dual stars, planetary Nebula. And then pillars of creation here looking pretty nice. So it's just gorgeous and this is where we live. This is all of us in many shapes and forms. We all came from this. So anyways, it is cool. Neat stuff. What a neat achievement for humankind. Yeah, okay. So now that we're back from that billion a year journey, let's... I'm so jet lagged. So what's amazing is there's an abundance of minerals and elements and energy. However... It's really far away. However, there's a chip shortage. Somehow there's scarcity, so let's jump right in. Okay, this week we really need stuff from ST. It's a chip shortage every day and every week. Okay, so life is augmented, but also life is kind of tough right now. So I'm not asking for the... I'm not asking for STM32, F7s, like everybody else. I just want some humidity sensors. And I'm not asking for the oceans to calm down. I get it. It's chaos. I just want to surf better. I need a board to surf on. So what's the part shortage this week for us? Okay, so this week it's ST's Capacitive Humidity and Temperature Sensor. I think it's the HTS-221, it's on the next page. What are we using it in? It's in this breakup board, the HTS-221. And it's like, we have so many temperature humidity sensors, but people really like this one and we don't have it in stock. We haven't had stock in like a year or so. And we ordered the chips a year ago and they haven't come in. They keep getting bumped. So could you please, please, please, please, please, send us a real. It's here in stock. I think we ordered like a thousand or a couple thousand. If we could just get like 500, we could at least fulfill some of the people signed up, people resellers who have back orders. That'd be really sweet. Thank you, ST. Yeah, so. I'm not asking for my control. Everybody else is like, I want an STM micro. I know I'm not gonna get those, but I think I didn't get this. So ST, we'll drop you a tweet. We'll drop you a note. We ordered 700 from Digikey back in February of 2021. The date keeps getting moved out. Please, please, please, we just need 700. Or maybe at least 500. Yeah, we've ordered more than 700. We ordered a cup, we ordered more, but the oldest order is 700 pieces. That's what we need. And it's been like a year and a half. Come on. Okay, so if you wanna see these in the world, we should pawn a star or ST, and maybe we'll get them. As senior ST. Okay, let's do some mailbag. All right, letters, we get your letters and we read them to our team and we also read them to you. I love Adafree. You can spend hours browsing every crazy product. Most recently, I've been working on a fun house, becoming a central device for my house, getting outside weather data via API to go with onboard sensors. I think my favorite product though, so far as a circuit playground line, I give them out to friends that have any interest in trying out electronics out the electronic world. I appreciate the continued work everyone does to advance the learning of electronics and programming. Thank you. Thank you. All right. Let's do some jobs board. Where's it been right along here? We're in a lot on the show. Yeah, but we're getting through it. Getting through, getting through, getting through. Well, we just went, we went to space and so time was lensed. That's right. Because we were moving so fast. We moved so fast. Everyone... Time sped up or slowed down. Everyone aged, but worth the same. Yes. So here is this week's job board. So you can go to jobs.aidfor.com. You can post your skills or if you're a company looking for amazing makers in the community, you can post up your jobs. Here's the jobs that were posted this week. First one is a hardware engineer, potential for a full-time CTO. No. At Bright, Smart Rings, Chicago, Illinois and the Pratt Institute is looking for a system administrator. So if you wanna... That's a good job. An art school. Being an assistant man at a university can be a very good job. Okay. It's time for some Python on hardware. Okay, this week I'm gonna go over Circuit Python Day in just a moment, but I wanted to go through the newsletter. The newsletter is chalky this week. Yeah, a lot of projects. One thing, so I'm on the fritzing... There's an RSS feed for their blog and that's the only... Updates once every year. I've read like few years, but when it does, I'm like... Oh. Because like, you know, I have like, I think 1,237 feeds that I kind of keep ambient awareness on and when the fritzing one lights up, I'm just like, oh, what's going on? So after many requests and years of waiting, their words, fritzing, finally got a simulator. So if you wanna check out the fritzing simulator, go to fritzing.org, check it out and look at some of the examples and some of the things that they have. So kind of exciting. I've known folks that have done full-on, they've made their products via fritzing. Absolutely. Yeah, so a circuit simulator is pretty cool. I use fritzing every day for our diagramming. We still do. It's a great diagramming tool. Yeah. Okay, if you want to learn how to make a web server on a Raspberry Pi Pico W, which everyone's calling PICAUS, check it out. And the other news that I really wanted to help get the word on on is if you're familiar with Moo or if you just like kind of an amazing approach to programming on Nicholas Tull and Tull, which is how he's known online, is doing an interview with the Circuit Python show. So do check it out. Nicholas's approach. What's the name we have for the British people who are their thinkers? Remember he had this word? Thinkers? Remember he's like, oh, there's the British word for people who tinker and think a lot? I've been called a Muppet, but I know that they didn't mean it in a nice way. What's funny is, I think- It'll come to me in a second. I think we had banned someone because they were being mean. Oh, yeah, and they called us Muppets. And I'm like, I love Elmo. And I'm just like, oh, cool, man. I love Muppets. I'm like, I'm just like, yeah, you know, I'm kind of like a Muppet. Like, you know, we have puppets and like, but it turns out that wasn't a nice thing to say. I want to say like a Badger, but that's not the word. It's something similar. Yeah, I guess I can look. And then- Buffin. He's a Buffin. Yeah, good. And remember we went and he said, you told us what a Buffin was and we're like, you sound like one. He's like, well, you can't call yourself one. Other people can call you one, but he's a Buffin. Yeah, if you- Yeah. I hope it didn't trick me into like, that's actually a very naughty word. I don't think it is. Yeah, I'm good. I'm a Muppet. So the other thing, and you know, we certainly don't mean for our newsletters to be like breaking news, you know, TMZ style stuff, but I think we do a pretty good job putting things in that are good for people that are doing electronics right now. And one of the things is like, well, what should I consider either to build my hobby around or like electronic accessories and more? And so Evan, the- I don't know what his title is now, but he does a lot at Raspberry Pi, the company and the foundation. I think he was like knighted and stuff too. Sir Evan Upton said, they'll probably have 2 million Raspberry Pi Pico Ws this year. So if you're thinking about what can you actually get, because we think about that a lot, that's one of them. And we are looking at circuit Python support for that Wi-Fi module. Again, you know, we had to wait until it was released. It's released under a license. We wanted to make sure that we could fulfill that license because there's obligations. Looks to be okay. And we just have to do the work of porting. So it'll happen. If anyone wants to jump in and help, we can guide you on it. It's right now we're just- We were already working so hard on Web workflow that we didn't want to put down an existing project to pick up another shiny squirrel. You know, we're already halfway through this Web workflow. But if anyone wants to help out with the porting of the Wi-Fi code from MicroPython into circuit Python, hit us up in the GitHub issues. I like your combination of what happens. So like new shiny and then squirrel all at the same time. So shiny squirrel. It's a Pokemon. Yeah, shiny squirrel. It's like a shiny squirrel Pokemon. Um, the other project, if you're, you know, an 80s kid or even if you're not, is someone made a kit control panel with circuit Python. And it's kind of hitting like all the parts of the brain. It's like, uh, nostalgia, uh, Python, uh, you know, that was such a cool car. And I want to talk to you. And it was so nice. And this is like- This is a cool project. Advanced AI back in the day before even people were thinking about it. And if you think about like what would, what would be neat, it would be like kit, like this friend that's helping you out. You're always getting in the mischief or like you're- Well, I like the kit was a little bit of, you know, a little bit of trouble, a little smarter. Michael, I'll come and get you. Michael, don't do that. It would tell him like not to smoke and stuff like, Michael, don't smoke. Yeah. At least that's how I remember it. So the other thing is, um, our big event worldwide together, Circuit Python Day, so August 19th. We're getting ready to post up all the activities, but we think we're going to have at least like an hour plus long, show and tell. So come by and show your projects. Yes. And we'll have some interviews. I think Circuit Python show folks are going to come by and maybe they'll be doing some stuff. So keep tuned to the newsletter, the website. We're going to have an update on CircuitPython.org. So we can have like a banner, by the way, so you can see like, oh, here's what Circuit Python Day is. Here's a countdown. Here's, so we're going to just try to even get the word out more and more and more. But we send this newsletter out every single week. Go to AdafruitDaily.com and not only you can get other newsletters, but you can get this one. And it's this wholly separate site because we never wanted anyone to think that we would spam them or do anything. And it has nothing to do with your store account. It's a whole separate thing. It's all free. No ads, no anything. Unsubscribe anytime. We make it nearly impossible to get spammed, at least from us. So check it out. And that is Python on Hardware this week. Okay, we're an open source hard work company. To prove it, we post it per code. And we say that we're going to keep doing open source and there's video of us saying it. So it'd be hard to back out of it at this point. But we also have 2,698 guides that show you how to make all this stuff. What's on the big board this week, Leida? Okay, so we have been adding... First off, we're porting Circuit Python to the ESP32. We've also been adding WIPR snapper quick start guides to many of our boards like the Feather ESP32, Feather V2, and the V1. So check that out for many of our popular Wi-Fi or IoT boards. You will start to see WIPR snapper quick start guides. If you see those, they're definitely supported by WIPR. And no code way to get IoT data logging and interacting. With a lot of our projects, you may not even need to do any soldering. You can plug-in sensors on a STEMI QT port and you can log them and then do web hooks, save data, store data, have emails triggered off of data, et cetera. We're trying to make it very easy for people to do IoT projects even if they don't want to write any code. Likewise, I think all these boards also got their quick start guides going. Brent, Katyn and Eva have been just like crunching through many of the board guides to add those quick starts. So yeah, check those out, especially if you have any of these boards as well. Ditto on the left, the Pico, ESP32 Pico. The creative sharing of Circuit Python library. I updated because Windows got fixed and I wanted to make that clear. For the QT Pi ESP32 S3, that also got a WIPR snapper page. And the Neopixelate got a Neopixelate support in S3 using the TFT driver. So if you have an ESP32 S3 chip and you want to drive eight strands of Neopixels with DMA, so no timing issues completely out of PSRAM or SRAM in the background, check out the Neopixelate library and now has a page for the S3. Okay, and now to the new guides. There's so many new guides. Although over there, the quick start, Adafruit IO WIPR snapper, I think that links to all the quick starts. So that got updated in addition because we're going through all these products and guides to add those quick starts. New guides from Knowing Pedro. We've got the OWL IR TV remote. It's, I think it just has like a cool, like Tiki lounge look. It's this like funky owl and it has IR LEDs at the eyes and you can have it record IR and then play it back when you press the button. So it's like a nice like one use infrared remote or controller. And next up, the super simple Sunrise lamp. This is Carter. We had a couple of people who really wanted Raspberry Pi's because they wanted to build a, this project was a Sunrise lamp. This is really useful if you have young kids who don't know how to read a clock but they need to know when it's time to wake up. And so you make a clock that changes color. It's when they wake up and if it's yellow, it's okay to wake up and jump into mom and dad's bed. And if it isn't, go back to bed. So this is a lamp that uses an ESP32 cutie pie and a Neopixel ring. You don't need a Raspberry Pi to do it. And it has the correct time, even when daylight savings changes or if you're in a different time zone, actually figures out the local time based on your IP address. Finally, Liz made a new guide for the LSM6DS3TR, which is the 6-DOF sensor that we're using to replace the LSM6DS33, which was in short supply. And then during the chip shortage got completely discontinued. So we are re-spinning that board so that board's been updated. If you've been using anything in the LSM6DS series of IMUs, this is a great IMU chip. It's actually a little bit better than the original DS3 and DS33. And it's available and you can get it and it works very well. So a lovely IMU toss on a magnetometer and now you've got a full 9-DOF sensor. Okay. And speaking of Liz, I'm here a little video that Liz put together that I wanted to play. In the Walk Melotron Cassette Player Mods Learn Guide, you can follow along with two different ways to hack your cassette players. My build breaks out the cassette player's motor and controls it with a L9110 motor driver and circuit python. A potentiometer controls the speed and direction of the tape loop for recording or playback. John Park's build is the Walk Melotron. The Walk Melotron is a speed controlled tape player, which uses circuit python running on a cutie pie, plugged into a DAC, which generates voltage in order to change the motor speed through the speed control potentiometer built into the Walkman. Here a tritone is being played and then when the MIDI keyboard has a key pressed, it adjusts that speed and tone. Check out the Learn Guide on the Adafruit Learn System to find out how to build your own Walk Melotron. Okay, and we're an advanced manufacturing company in New York City. Here's some footage. And it wouldn't be factory footage without a little bit of time lapse from the Disney building across the street. Boom. It's a pretty time. We're going to do it too far. We're going to show the IR owl. And then a really cool speed up of, I guess that's an excavator. It's a cool giant truck, but 3D printed. Small. Yeah, here we go. Hey, what's up, folks? In this project, we're making an IR TV remote with Circuit Python. We thought it'd be fun to 3D print an owl and use it as a universal TV remote. It has an LED arcade button and two IR LEDs for turning on and off our TV. This is powered by Adafruit's Cutie Pie RP2040 running Circuit Python. The IR LEDs are embedded inside the owl's eyes and the IR receiver is mounted to the snap fit case. Press the button to transmit any IR signal and have the built-in NeoPixel light up and change colors. The Cutie Pie is fitted onto a Permaproto PCB and secured to the bottom cover with screws. Liz Clark wrote the code for this project using the IR remote library for Circuit Python. Follow along with the IR sensor guide and learn how to decode pulses from any IR remote. In the Mew editor, we used the REPL and debugging mode to capture pulses from our TV remote. Once we have decoded our pulses, we can paste the array into the Circuit Python code. The code stores two IR pulse arrays, one for powering on the TV and the other one for powering it off. The colors are set up with green and red colors and changes depending on which IR command was sent. With Circuit Python, you can quickly iterate on code and experiment with different IR signals to control just about any compatible appliance. We hope this inspires you to check out Adafruit's line of RP2040 boards and try out Circuit Python for your next project. If you'd like to build your own, check out the guide at learn.adafruit.com. So before we go on to some IONMPI, let's just do a reminder. Make sure you go outside tonight and check out the Supermoon. But then after you come back. Oh yeah, you should use the code. Use the code. Supermoon. That'll remind you. That big thing in the sky is reminding you to use the code Supermoon. We worked it out with the universe. Thank you. Um, all right, let's do it. Okay, IONMPI. It's brought to you by Digikey. This week's new product from Analog Devices. Lady Aida is... This week it's the Max 98365, which, as you can imagine, was born initially at Maxim. Analog Devices purchased Maxim. So now it's an AD device. But, you know, Maxim has neared my heart. So I think they get a little bit of credit for the original engineering and design work. So this is an I2S slash TDM slash left-justified mono-class D amplifier chip. It's what it looks like, you know, in the rendering. It's a BGA 12 pin chip, which we'll talk about in a moment. And it is a teeny cost-effective 14 volt plug-and-play digital class D amplifier. It's got a lot of specs, but the things I thought were most interesting is, one, you can power it from 3 to 14 volts. So you can run it from, you know, lipo batteries, AA's up to 12-volt batteries. It does very good at powering both 4 ohm and 8 ohm and 16 ohm loads up to 14 watts. I think it's 18 watts on the high end of 12-14 volts. If you want low THD, of course you'll go down a little bit more. But you know, easily 10 to 18 watts into 4 ohms. It's class D, so it's very efficient. The efficiency is very good into 8 ohms. It's very tiny, it's very powerful, it's 5-volt logic compatible, and you can use it with a variety of different digital audio interfaces. So this is kind of like the typical application. It's got this kind of funky thing going on there where there is, you know, normally you'd have, you know, clock, frame clock and data out. That's like your standard I2S or TDM multiplexed data. And by connecting to the three data pins, there's like DAI, DA0, DIA0, DIA1, DIA2. And by changing the connection, it will auto-detect whether it should be like in left or right mode, which I think is kind of neat. It also means, of course, it can kind of auto-detect the bit rate. And as we mentioned in the moment, we don't need a master clock. But really, there's not a lot of things going on here. This is a very simple design. And it's tiny and, you know, does the job. It actually reminded me a lot of the Max 98357, which is a similar part number. And this is one of my favorite I2S amps. It just works, you know, like the Max 98365. It's a single-plasti audio amp. You know, you just have a couple of passes on the output, but it does a great job with I2S in. And I, you know, use this with Raspberry Pis and microcontrollers just fine. So the only thing about that amp, this one is it only goes up to 5 volts power and only does, I think, like 3 watts or so. Whereas, like I said, this new amp can do up to, you know, 18 watts. Only thing is, this is a cool, this is not the chip itself is a different chip, but this is an SEM photo of a WLP. It's a WLP. So it's 12 pins, four by three, and it is .4 millimeter pitch BGA, which is, you know, a bit tough. But that said, the inner pins, you can usually keep disconnected. You can use the outer pins, so at least you don't have to do, you know, blind vias or plug vias. You can pretty much, I will show in a little bit, you can kind of get away with just cutting to the outer pins to do most of the things you want. In a lot of PVCB's houses these days can give you a pretty good clearance on your .4 millimeter BGA pitch devices. So, you know, I'm less scared, as I used to be, of .4 millimeter pitch BGA. In fact, the matter is, a lot of the more advanced chips are coming in these chip scale packages. As I mentioned, this has great power output. At 12 or 14 volts, you can get into 4 ohm or 8 ohm, you know, up to 18 watts, 15, 18 watts, you know, with very low total harmonic distortion. So, it sounds really good. There is a gain selection pin, because like as you imagine, you know, it doesn't have I squared C for control. Like some nice I2S amplifiers use I squared C for volume control. This one does not. So, instead, you use there's a pin, which you can connect or disconnect if you want to change the gain. TDM, I think the gain isn't adjustable only in I2S slash left justified. Again, this is one of the inner pins. So, you know, you might want to just leave it unconnected. So, the gain is 18.5 volts, and then just adjust your input signal to make sure it doesn't overwhelm the speaker. And this is the package. It's super tiny, so you can see the pitch. And I think it's like, it's like one and a half by 1.75 millimeters. So, it's like tiny. It's a tiny chip. This is some of the examples of wiring. So, you can see the gain slot is like the middle right pin. So, you can either connect it to ground input or leave it floating without having to route through the GPIO pads. So, it basically means like, look, you know, if there's two gain options that were user-resistor, that one's a little tough. But if you don't mind just bridging the BGA, you can get three different, you know, hard select gains. You know, it's not like a thing that totally kills me. Would have been really cool if it was only outer pins. It would have been easier to route. But I think the fact of the matter is everyone wants, you know, AirPods-sized amplifiers these days has to be ultra tiny. So, the interesting thing is this digital audio interface configuration. So, basically by switching around the pin connections, you know, it does auto-detect some settings, but whether it's like the left channel, the right channel, or stereo mix, depends on how you connect the data clock, the left-right clock, and the data itself, the data pin. The three pins for I2S. Which way you can figure them tells you which channel it's on and whether like, you know, does left justify it or I2S. So, there's a big description of it and there's a couple of example wiring diagrams. For example, here you can see, you know, here's how you can wire it up and it's like one of them would be your left channel and one of them would be your right channel. I'm trying to think which one. It's like one of the pins is connected slightly differently. I think so, and it's connected the same. Oh, it's like DA1 and DA2 are swapped and that's how it knows whether it's a left or right channel. So, the previous break that I talked about, the max 85, 375 or whatever, there's a pin you have to short to tell it whether it's left or right. In this case, you just change the pin wiring order. So, just keep an eye on that. One thing I do like about this is like the max 98, 357. Again, one of my favorite I2S amps is there's no M clock. That means you only need three GPIO to connect it to your I2S connection onto your mic controller. And most importantly, on single board Linux computers like the Raspberry Pi that does not expose the M clock pin, this will work. You know, you can always generate an M clock with a separate oscillator, but why pay 50 cents and take it more board space when it'll auto generate the M clock signal on its own. Very handy. Part of the auto detection of like what mode it's in, I2S or TDM is that it doesn't, it will, it will auto generate that M clock from the bit clock, but not all bit clocks are valid. Now, all that, I looked at them and all them seemed reasonable, eight kilohertz, 44.1, 88.2, et cetera, 192 kilohertz. Just keep that in mind, like not, you can't like use 12 kilohertz. I don't think it likes that. So, it's expecting kind of standard I2S connectivity or TDM connectivity. And finally, just as a note, I think that there's only one version in stock right now, but there are four versions, A, B, C, D, and they basically depends on how long it takes to turn on and when data is valid. So, it's like there's a little bit of a, like does it ramp up the volume or does it just turn on? Does it take time? You have 13 milliseconds or 1 millisecond. So, look at this table again, I think only one of them is available right now. But if you need a custom one, contact ADI and they will hook you up. Available on DigiKey. It's in stock. And we mean that. 915 at the time of this printing. Yes. By printing, I mean screenshotting. For reals. Yeah, so you can get them. You actually can get them. And I can, I just can show quickly the valve board. I did pick one up because I wanted, actually it was also like, maybe I'll make a breakout out of this board. So, that's the amplifier. So, it's quite tiny. And this is a, you know, very nice teal. It says maximum integrated, but you know, again, it's ADI now. But that's the chip. But you can see, you know, the total size of the amplifier. I mean, these are all the headers and connectors. But the amplifier itself is, you know, maybe three millimeters by three millimeters, including all the passives you need. Okay. And that is this week's Ion API. Okay. Before we go off to new products, Supermoon's the code. Make sure you go outside and see our satellite. Yes. You only have one moon. Right now. Okay. So, let's kick it. Okay. Alrighty. First up. Okay. Good job. In the meantime. And it's intended for industrial and prototyping uses. Okay. Next up. Next up. This is an update. It's a STEMI QTification of our popular DRV2605L. This is a really great video that photo got because it shows, it's actually going through all. There's like pre-programmed 250 plus ish, you know, click and tap and buzz and strong buzz and medium buzz, pre-programmed designs for vibration motors. Also works with ERMs, although I don't own any. It's now STEMI QTified. You still need to solder or connect on the vibration motor. But for haptic stuff, you can just plug and play, you know, connect it with a STEMI QT like so and buzz away. Also, you can always strip the wires and probably just twist them on. It might work. Okay, temporarily. But I do like this little haptic driver. It's inexpensive. And, you know, if you want to drive these little vibration motors, you don't necessarily want to get like a full H-bridge going and like programming all the different ticks and styles and shapes. It does a very good job of making a haptic interface. Everybody wants to make that project where you make a belt and it buzzes based on what direction you're going. Now you can just plug and play all of them together. Yes. Okay, next. We got an assortment. This assortment. So I actually got this for me and then I was like, you know what, other people probably want this too. So this is a collection of like 25 different buttons and you get 10 pieces of each. So I think that's just enough that you can like make trouble. But it's a mix of different sizes, different stems. They're all kind of like standard buttons. So you will be able to get more of these. I'll try to find the matching Digi-Key. Yeah, I'm going in there. Hold on, hold on. So for example, here is a sort of standard through-hole 12 millimeter by 12 millimeter tactile switch. So this is your standard flat top. But then also we have the SMT version. So same thing, but surface mount. So there's a mix of surface mount and through-hole. Maybe you're like, well, I like that 12 millimeter button, but I really want a tall stem. This one has like a five millimeter stem, something like that, maybe six, sorry, 10 millimeter stem. Or maybe you're like, well, I want one with a cap. So you can add a nice button cap on the top. This is the version with a cap stem. There is a bunch of the six by six millimeter tactile switches. So this is your standard six by six by five. This is a six by six by 4.3. The height of the actuator is a common thing you have to tweak and they're always available in different sizes. So a little bit more flat. I like the five, but maybe people want the six. There's the right angle version. So this is a six by six right angle style. So it uses a slightly different pinout. So watch out for that. Let me see if I have other six millimeter. We have six millimeter flat SMT. I like this kind of button. I remember seeing it first on the Arduino Uno. So same size, but SMT version. There's also one that is that boxy shape, but also SMT. Sometimes we use these when you need a little bit more height. There is the two pin right angle through a whole six by six millimeter. So it's kind of like, I've actually never used these. It's a little funky because it's right angle, but doesn't have that extra set of two pins for mechanical strength. So it's just a two pin, but flap is still maybe useful. Let's see, we've got another one. This is a four point five. So these are cute. Sometimes you see them like, oh my God, it's a six by six millimeter tactile switch, but it's tiny. It's a small version. So it's so cute. Four point five by four point five. Oh, here's a two pin, six by six. Again, a little bit weird. You don't see these very often, but very breadboard friendly. No wonder which pins are connected to inside together. These are very easy to understand. So these are good for repairs as well as, of course, designing new products. And then there's like a bunch of other small switches. These are, let me be less common, right angle four point five by four point five. You know, these are pretty common. We've seen three, three millimeter by six millimeter SMT right angle. We use this, the style lot, no right angle designs. SMT right angle three by six. So it has little holes in the bottom. You have to punch in to give it mechanical strength. There's the right angle three by six with a lot of mechanical support on the back. There is the tinier three by six, the slimmer style. These are very, very cute and fashionable. The taller three by six. I know there's so many buttons. So this is a taller style. I think we use this style on our pie TFT. And then a bunch of small flat, oh wait, there's one more three by six. This is a, oh, it's a smaller actuator. So it's only the four point three height, not full five. And a lot of tiny little tactile switches, right angle, flat tactiles. Like we use these on the cutie pie. These have a like slightly bigger actuator. That's kind of nice. These are ultra flats. These are like sometimes called dome switches. This is, I don't know what this one is called, but I see, you know, SparkFun really likes using these little metal buttons with the gold plate. They're four by four millimeters. Here's this ultra small flat one as well. So you get all those 25 different buttons, 10 of each. Great for prototyping repair. Or if you're like, how big is a button that's 12 by 12 millimeters? Well, now you know. All right, let's keep going. Okay, next up, my goodness, is this motorized pot. I've always loved motorized pots. You see them on fancy AV equipment. You know, you can load a setting and all the potentiometers will slide into the location that you had previously set. It's pretty much the coolest thing and maybe the reason why many people go into music production. Yeah, it is. It's like, if you're a music producer, should I go to the overhead now? Yeah, it's going to be overhead because I really have to show off. So I have this. I know, it's excited. It always has like a different feeling to it than other things that move. It's like, it's alive. It's definitely alive. So this demo is, I've just got my feather and motor wing. So this is a five volt to 10 volt motor. You do need an H bridge to control it because going left and right basically is inverting the polarity of the motor connect. So you need a full H bridge, but we have many in the store. When you can, you know, you can make a move to the left and to the right. And then when you don't have a voltage, you can move it wherever you want. And then you would read the potentiometer signal off the bottom here. And it would tell you where you are. So here's how it works. Like let's say you're like, oh, I want it to be in the middle, which this isn't going to do because I have this pre-programmed. You would set it to the middle and then you tell your microcontroller or microcomputer, hey, read this resistance. So it was the analog voltage. And then it would, if you want to recreate that, it would move the motor left or right until the reading matched up and it would stop. And then it would release it so that you could, of course, tweak it. After it's been set. So the motor and the potentiometer are separate. It's not smart. It's not like you tell it, there's no way to tell it like, oh, if I give you half the voltage, it'll go to the middle. The motor either is on or off, pulls it all the way to the left, all the way to the right. That's all it knows. The position control has to be done separately. And then this is the slider. Note it's metal. There is one pad here. I don't know which one exactly, but it's in the datasheet. That's mechanically or electrically connected. You can use it as a capacitive touch detector so you would know if somebody is touching it so you can release the motor. This has everything. It does have everything. So we'll probably use it on a project, but I wanted to get some of these in stock so we could do some cool audio projects with it. All right. And the star of the show tonight besides you, Lady Aida, our team at Aida Fruit, our community, our customers, and everyone who keeps this going is... The LSM-6DS-3 plus LIS-3MDL. This is a 9-DOF sensor using two great ST sensors. We used to stock one which had the LSM-6DS-33, but the DS-33 was in short supply and then during the ship shortage was basically completely unavailable anymore. And so we've replaced it with the LSM-6DS-3 TRC, which is a really good quality, 6-DOF IMU, adding a magnetometer. Now it's a 9-DOF and the nice thing about this is now you can use it with sensor fusion to get full three-dimensional orientation in space. And so we'll update our guide, of course, to show you how to do that. But this is a very affordable, easy to use, and well-supported IMU. ST has libraries for it. Of course, we have Arduino support, CircuitPython and Python support as well. It's also got some funky... We mentioned this when we sold just the individual 6-DOF IMU. There is a built-in step counter, pedometer, and lots of interrupts on motion. There's also like FIFOs and stuff. Our library doesn't support the FIFOs, but if you are willing to use the ST library, the sensors themselves are actually quite powerful. And then if you need higher-quality gyro, you can always upgrade to the ISM-6DSO or the ISM-330. So I thought I would just show on the overhead. We have a quick little demo just showing off... Not nearly as big as the accelerometer, so let's zoom in. So this has got accelerometer and gyroscope, and so you can see the accelerometer. It measures about 9.8 meters per second, you know, depending on which the orientation is. And then the gyroscope... The gyroscope, when I twist it, it goes a little nutty. It's like, wow, you're moving many degrees per second. And then at the bottom, the magnetometer is measuring where we are in relation to north. So you can use that as a compass. But altogether, you confuse the data to tell you which way orientation is with quaternions or Euler angles. We have a library and example code on how to do that. But there's also a lot of tutorials on how to do that with fusion data using these nine entries. All right, and that is new products this week, Lady Aida. Yes, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new, new. All right, so don't forget the code SuperMoon. And while we get over to the questions, I have some lined up, but do go over to Discord to put up your questions. If you put one in, I do have it, but feel free to put it in again. It doesn't matter. It's fine. It doesn't cost anything extra. Do go over to discord.aida.it.discord, and we'll get over there soon. Let's do some top secret. Yes. This week's top secret is a twofer. First, we're going to show a new line of things we're making, and then we're going to tell you what we're calling them. So the Raspberry Pi Pico W is out, and everyone's calling it PyCaus, and they're saying, well, what do we call these? And they're like, well, we'll call it a herd. And then everyone's like, these are cows. PyCaus, cows, cows, cows, cows. Everyone likes cows. People love cows. And so this is one of our first, well, we'll tell you what we're calling these, but this is a Pico W permit. Prototyping add on. You plug it in, you can solder it, socket it. So it's like a proto feather wing or proto shield. But as I already said, button. And it goes underneath the Raspberry Pi Pico or Picole. Yeah. And one of the things is, so there is shield with Arduino. There are feather wings. There is hats. There was gizmos. Gizmos. What was it, beagle bone? Capes. Capes. And so we're like, well, what are we going to call these things? And usually Lady Aida will tell me like go on the weekend or something like that. Like, hey, like here's something we're doing. Here's a product line that we're coming up with. What are some of the names? Let's go check with our trademark and copyright lawyers and all that stuff to make sure we're not doing anything with someone else's name. So we're calling these bells and specifically cowbells. And let me just give you a little history. So back in the day when we first started doing robotics in circuit Python, I did this project. And I should say Jeff Epler came up with the name cowbells. And this was one that like it's been in the back of the mind forever. It's like, oh, maybe we'll have like a thing called bells. But he came up with it. And I'm just like, oh, that's it. I'm so like, when I was relieved, I didn't have to like go to that path to find it. But the other thing was like, oh, this fulfills the destiny of a thing we want to do. So we did this project with Cricut that used circuit Python. It was fairly new at the time as far as robotics. And I wanted to do an homage to the SNL skit with Christopher Walken about more cowbells. So I'm just going to play a little bit of that. Maybe at the end of the show, I'll play the whole thing. But I'll just show you where some of this came from. Yes, that's a smoke machine. Yes, that's a little more designing electronics in the background. Yes, that's what we do at night. So that's just the start of it. And maybe I'll play the video later. So we had this idea. It's like, OK, bells, it's here. We're going to do a Cricut cowbell don't worry. But then we're like, OK, now we can do some of these logos and stuff that we've been thinking about. So we're always trying to figure out a way to use a UFO and a cow, but we're not going to do that. So then we came up with, well, let's do bells and have it look like a cow. We're not going to use the ones that have any Raspberry Pi logo elements as cool as it would be. But it's fun to play around in graphic design. But we did move towards like, OK, this is a pretty neat thing. It's black and white. It'll go on PCBs. It's a bell. It's cow-like. For some people who remember gateway electronics, they did computers. That's kind of neat. And so we like the idea of these being called bells for the Pi cows. And then more cowbell. So every time we release one, more cowbell. We'll have a cowbell. And when Lady8 is like, well, what should I do today? I'll be like, more cowbell. And we have some of the art ready to go. And then, of course, you know. Everyone loves drawing cows. Yeah. Guess what? I got a fever. And the only prescription is more cowbell. More cowbell. So that's this week's top secret. And now you know what it's like to live in our heads. Yes. OK, so we're going to do some questions. And more cowbell. Gold-plated diamonds. OK, so first up. So DJ Devon asked a question about a 16 megabytes flash chip by Cyprus on Digikey. And Scott came in and answered the question. So I'm just going to skip to the end. You'll need a custom build. The CircuitPython Dev channel is where we can help. So thank you. Yeah. You can update the flash memory chips and have it work CircuitPython. But CircuitPython needs to know how big to make the disk space so you can make a custom build. But people have done that. We had, I think, the QT pie had a couple different builds based on what size flash people sawed it onto the back. And so it's not that hard to do. You might be able to do it. And then we would add it to our collection of boards that are built for CircuitPython. OK, next up. This is a request. Todd Bot would really like an Adafruit I2S stereo output board that has both line out and headphone out, maybe via one connector. Yeah. I don't know of any, you know, only the WM8690, I think, has that many outputs. And, you know, because you want speaker and you want line out and you want headphone out. It's just tough. Like a lot of chips don't have all these things. And a lot of I2S chips have been very hard to get also. OK. I want to say hug report and special thanks to Rich Sat, who's volunteering to do the MicroPython to CircuitPython port for the P-Cal. Bonk, bonk, bonk, bonk, bonk, bonk, bonk, bonk, bonk. I got a fever. You have to get the cowbell. Where is it? And the only person. What? I got to have more cowbell. We have one. I have a cowbell. We have to go get the cowbell. Yeah. All right. OK. Next up. On the motorized linear pot, is it OK to move the knob by hand? While it's being driven by the motor, will the motor slip in a good way? Well, there's no such thing as motor slip in a good way. It's geared, so you don't really, and it's plastic geared. I wouldn't recommend it. I only ran it at 5 volts, which is a little bit underpowering. And you can kind of sort of move it. But honestly, you should wait until detect if someone's touching that capacitive touch signal. And if they are, then move it. Or whenever you're moving it, release it immediately. Don't hold the motor, which you don't want to do anyways. It's not good for the motor to hold it in a position. You want to move it to the location till, and you saw it move quite fast, move it till it matches the resistance you want, and then release it so that people aren't fighting against it. Yeah. OK. There's a little bit of a debate in the chat. Not really. This is a joke. So the phrase that Christopher Walken said, I thought it was gold-plated diamonds, but the news in the chat is it might have been gold-plated diapers. I thought it was gold-plated diapers. I thought he said diamonds. I don't know if it's been a while. I think it's gold-plated diamonds. I think diet. Why would he say gold-plated diapers? Because it's Christopher Walken. It could be either or both at the same time. He has quite an accent in that skit. Yeah. He plays himself. He has another skit in the SNL that's really good. It's like the weird tenant skit. Yeah, that is a pretty good one. It's a really good one. Very New Yorker. Yeah. So how's the sourcing of the LED filament? Nudes go and pasta stuff. It's been looking for a special project. They're on their way. I think it'll be a week or two. They're getting packaged and getting ready and being sent. Yeah. We didn't have to do a special order with the factory to get all the different colors and sizes. Yeah. Next. Two-part question. Looking to take the QDPI portable. I know about the BFF. Just have a different thought. Okay to power the ESP32X QDPI by USB-C with 4.5 volts, 3AA battery holder, and two, if I order the USB micro-B breakout board and USB-C to be micro-cable with the breakout deliver power going for the micro to USB-C. I don't know, actually. USB-C cables sometimes have chips inside of them that do power stuff. If you want to power it portably through the USB-C port, honestly the best way to do that is to get a USB like lipstick battery charge kit, you know, like the ones that you can get at the store for like, you know, five, 10 bucks and just use that and then just plug it into USB and then charge it that way and power it that way. If you want to do with the battery, I'd really go into the battery pins on the bottom. That's really recommended. And I don't know with USB-C to micro-B cables, I can't guarantee what they do because they're funky. V-Bus may not necessarily be V-Bus. It should be, but I don't know for sure. Okay, ladies, these are the last three questions of the night because I got to get you out of here. Yeah, I got to go. Okay. Hey, DeFruit, I'm joining the stream and that new NineDolph sensor looks awesome. I'm building a data logger with a nano and wanted to ask for suggestions for detecting power without losing data to the SD card. I know capacitors in the mix for that solution, but I was wondering if anyone had any suggestions as to how to go about it. Thank you. It's very hard. You know, you can lose power anytime, but yes, basically normally you would have a battery back up so you could flush data. There's really, you know, SD cards are, these days, they're quite good. You know, you do want to flush your data often, but if they are pulled during a write, it might be okay. Sometimes people use something like LittleFS or they raw write so that they just write like one block at a time. And so if you lose, like you're not writing to the FAT file system or you pre-allocate the file and then you like write into it. So basically what you don't want to do is like corrupt the file allocation table. But yeah, it's the SD cards. There's always a risk of that. And that's why people use FRAM or FlashMemory sometimes where it's like you only append data to your data logger. So sorry, there's no, not a really good way to do it and shut down just in time because SD cards also use a lot of power when writing. Not a question, but a statement. The connector they believe for the LED matrix power is this one. It's called a VH connector, 3.9, 6 millimeter pitch, 2, 3, 4, 5, 6, 7, 8, BP, 2 dash, 8, P, PIN. Sounds great. Sorry. Yes. I'm sure there's actually quite a few that fit. I read all these words at once. Is the STEMA QT IR transceiver a possibility? Not easily. That's a tough one because there's no IR transceiver that goes over I-squared C and converting IR to I-squared C kind of sucks. And then since that other one was the statement, we'll sneak this one in. Can find I2S ADC. Well, an I2S ADC is like an analog input and you can, but they're usually set up for microphones or line-in. So it's not like you can, you know, they also are fixed frequency. Okay. And that is all the questions. Okay. Thanks, Eric. Yeah, we got out of here at 9.15. Thank you, everyone. So all were so good. You'll get some more cowbell. I gotta have more cowbell. Guess what? I got a fever. And on the way out, I'll play that other video in full, which has a smoke machine and LEDs and lots of- And me ignoring him. Yes. So special thanks to Jesse May running things behind the scenes here. A special thanks to all of the folks in the community and the chat. Thanks for making this a really fantastic, fun show this week and more. You all keep us going. Very much appreciated. Thanks, everybody. It was fantastic to tell folks about all the celestial events, including the Super Moon, which is tonight. Super Moon. And, you know, what a cool, weird, amazing, scary, joyful existence we all got a chance to look at this week. What a great reminder how special and amazing it is to know that we are looking at this thing and we are this thing, looking at this thing, looking at this thing, doing this thing. Hey, good night, everybody. Good night, everybody. This has been Native Fruit Production. Here's your moment of zener and I'll play the video after I get us out.
