 Life from New York, it's Asus Engineer. Hi everybody and welcome to Ask Engineer. That's right, we're broadcasting live from the Ada Food Factory in downtown Manhattan. This is not a green screen, although we're warmed up from the lights here. It's me, Lady Ada, with me, Mr. Lady Ada, at the Ada Food Factory where we manufacture all the goodies. Right now the factory is quietly sleeping, everyone's out, and we're MaxVax, that's why we're not wearing our masks, but usually we do. We've been maximated. We do have an exciting show for you tonight, about one hour of the latest news, updates, videos, tutorials, products, and more. That's right. Mr. Lady Ada, let's kick it off, let's get right into it. On tonight's show, the codes are back, MSBuild is a code, 10% off just for this hour live. We're bringing back the codes, but we're doing small steps at a time, so put stuff in your cart and use the code MSBuild, this code's going to go away after we're offline, maybe it'll be around for a few minutes more, basically 10 o'clock Eastern night time has gone off, so use the code 10% off in the Ada Food Store, anything that's in stock and things besides like, give a certificate, other stuff that aren't covered by this. We're talking about live shows, including Show and Tell, Desk of Lady Ada, and JP Show, and Deep Dive with Scott and more, Show and Tell, people around the world showing and sharing their stuff. We have a little bit of update with Show and Tell and how we're going to do things in the show going forward. Time travel around the world, makers, hackers, artists, engineers, and more. We've got jobs from the Jobs Board, jobs.adafruit.com, New York City factory footage, 3D printing, INFPI, new products, top secret, and we're going to answer your questions. We do that over in Discord, adafruit.it, slash discord, where you can join all 29,000 of us, 24 seven, all that and more on Ask an Engineer. First up, let's pay some bills. Don't forget the code is MSBuild. I can't believe we're going back the code. We're back. We're back. But it's only during the live portion of the show. And I do want to thank everyone on our team. Here's just one of the photos that we were doing right before the pandemic started. We'll have some new company photos of everyone soon. But thank you so much, everyone, for supporting us. And now it's time for us to get back and we can do some discount codes. So that's why we have that code. But when you shop, you can also get free stuff. That's right. What do you get? We have the freebies. We have breadboard, 149 or more. You get one of many Stem-A-Q-T boards. We have a range of about 20 different boards we're giving away. You'll get a different one each time if you make an account and register. Because that way we can keep track of what we sent to you. Otherwise, it's random. 190 or more, you get free UPS ground shipping in the content of the United States. And 299 or more, you get a free Circuit Playground Express, which can run code.org, CircuitPython, Arduino, Rust, all sorts of different languages. It's got all the code, all the sensors and buttons are built in. So it's a great way to start. Just recommended it to a teacher today. You were like, can we get started with it? And they said, pick up some Circuit Playgrounds. All right. And keep in mind, Monday is a holiday. So when... No postal. There won't be a postal and I don't believe there is UPS or DHL. So just keep that in mind when you place your order. All right. Show and tell. We used to go over the show and tell all the folks that were on it. And what we're going to do is just suggest that you watch the video because we have lots of folks and we want to save that time for more Ask an Engineering each week. So go to our whatever video channel, usually people use YouTube, and check out all the show and tell folks that are on there each week. It's some Adafruit folks and then folks from the community and then folks we don't even haven't even met yet. Check that out there. It's part of our Adafruit Live Series of shows. Every single week we do Desk of Lay Data, that is on Sundays. And the first half of the show this week you showed what? Okay. We showed the RP2040 Connect, which we just got a working CircuitPython build force. It's exciting if you have an Arduino. I also showed my update to the STEM a friend. I showed this a long time ago with a SAMD21. Now it's an RP2040. I showed us some speedups that I did for the Arduino core for the RP2040 as well. And then we went into the Great Search. Yeah. Which was? Well we do. We do the Great Search. Yeah. The catchy tune. And in the Great Search, which is extremely valuable right now, LayData uses all of her powers of digikeying. For good. For good. On the site. And this week you showed how to find. Limo Connectors, which we saw in some very fancy keyboard cables. But I've used Limo Connectors. They're really high quality, you know, medical or aeronautical engineering spec parts. They're not cheap, but they're really, really nice. And so if you need something that has Push-Pull Connect inline is solid and rugged. And weatherproof. Lemos are awesome. And they come in a whole bunch of different sizes and pin counts. So I show them off here how to find them and spec them. And don't forget, you need both halves. Okay. Next we have JP's product pick of the week. This is, I think, one of the only shows that broadcasts live from a product page. Within the page. And within the page itself. And there's a discount just for that product. You don't even need to do a discount code. And this week's video, JP, take it away. Rotary Trinky. It is a USB plug and play rotary encoder board that also has a NeoPixel for feedback and a capacitive touch for additional input. This sends USB HID commands that can adjust that frame forward, frame advance, one frame at a time. I programmed this to turn on closed captioning when I click the little button. And I've also set the cap touch slider as a play pause. It is the rotary trinky. It's a USB rotary encoder that plugs right into your computer and allows you to use a rotary encoder, click and touch pad. The cool thing about JP is like, I give him this rotary trinky art and I'm just like, hey, you're going to use it for stuff. He really uses it. You use the heck out of it. All right. Also, JP's workshop is on Thursdays. Here's a little bit of a preview of a project that we showed on show and tell, but he also just sent me over the video, so now I'm going to share with you. And a new feature we're doing now is the Circuit Python Parsec with JP. It's due to make good minute, and it only would end up as a minute once in a while. It was usually like two minutes, but the Circuit Python Parsec doesn't have really a time thing. So here's a little two minute video on a special tip with Circuit Python from JP Show. For the Circuit Python Parsec today, I wanted to talk about analog output. So we've talked about digital in, digital out, analog in, and now analog out. So these general purpose in-out pins, in this case using the QDPI, a lot of these pins can serve many different duties. In the case of this board, the A0 pin can act as an analog output. So that's a digital to analog converter, DAC. What that means is we can send it commands and it will send a voltage varying from zero to 3.3 volts, which is the range that this board can do on those pins. The code that you need to do that is very straightforward. So I'm importing time so that we can do pauses, importing boards so that we get the pin definitions, and I'm importing the analog IO library. Then I set up my analog pin by calling this analog out equals analog IO dot analog out and then name the pin, in this case, board A0. That's the pin that I have this yellow wire plugged into, that's running to one terminal on this meter, and then my black pin there is going to ground and the other terminal on the meter. And then in code here, I've just set up a little variable that's the maximum value, so in this case 65,535 is the maximum value that that can go to, which equates to its top voltage. And then I also set one up for half of that, an integer of half of that. Then in my code, all I'm doing to test this out, what I'm doing is I'm sending the value of zero, waiting a second, sending that half value, and that's when you'll see it ping up here in a second, it'll jump up, boop, half, then full, boop, then drop it to medium, drop it to zero, and then I'm using this little range for loop to sweep through every value pretty quickly, and then drop by subtracting one from that so that we drop down back down to zero. And so that is how you can use an analog output inside of circuit Python. And that is your circuit Python parsec. Okay, and tomorrow is deep dive at Scott. You're saying, oh, he's usually on Fridays, yep. But money's a holiday, and Friday's taking off, Scott's taking off on Friday. So it is tomorrow, not Friday this week. All right, time travel. There is a whole bunch of stuff going on in the world. And specifically, you know, a while ago, we showed the Loeb kit, we teamed up with Microsoft, and it's a really easy to use, machine learning, training system that you can train models on it, and then you can deploy it onto a Raspberry Pi using an Adafruit BrainCraft hat. And we weren't allowed to talk about this until now, but the Microsoft folks contacted us, and there's an event they do every year called Microsoft Build. And if you haven't checked it out, please do. Today, I would say you have to watch the Scott Hanselman and Friends keynote segment. He's funny, they're all funny. And also- And actually, he's like friends. It's like friends, but a keynote. I've seen, been, and been part of, and had to help write or produce keynote stuff. This was really good. And they asked Adafruit if we would show some cool stuff. And Kevin Scott, the CTO, the Loeb team, we all figured out a really cool demo that's real, that's helpful, that's useful, that has all sorts of things. If you look at, that's good for AI and ML. And so it's six minutes altogether. This is a little bit longer of a video than we normally play. But I grabbed it real fast, and you'll be able to see the intro from the CTO of Microsoft and then this special filming that we did. And this, you know, for us, it was kind of a big deal because the first time that we were able to do filming again with our entire team and have them here at the factory. So anyways, check it out. And the rest of the build videos are going to be on the Microsoft Dev Channel. But this is a clip from today's keynote with the CTO of Microsoft and our Lady Anna. Thanks, Ben. I'm amazed by what you and Jacob have created so far and really can't wait to see what you'll do next. Ben mentioned how excited he was to use a variety of home IoT devices to create immersive new experiences. The potential for using the combined power of the intelligent cloud and Edge to program for a wide variety of IoT and Edge devices is going to increase exponentially in the coming years. The opportunity for developers to create on this new ecosystem is going to be enormous. It's incredible to see what makers are already doing with technology and how powerful the hardware and software for innovating on the Edge is becoming. I suspect that any of you who are part of that group will already be pretty familiar with our next guests and their work. MIT engineer, Leigh-Maur Freed founded Adafruit in 2005 with the goal to create the best place online for learning electronics and creating products for makers of all ages and skill levels. Today, Adafruit is one of the fastest growing US-based manufacturing companies, a certified minority and woman-owned business enterprise and one of the biggest names in the maker world, creating phenomenally popular community-driven products and code. Let's join Leigh-Maur to learn more about how you can get started programming machine learning at the Edge with Adafruit and Microsoft technology today. Hi everybody, it's me, Lady Aida, and I'm here at the Adafruit factory in downtown Manhattan where we manufacture all of our electronic goodies from accessories for the Arduino or Raspberry Pi boards to our very own Feather and Circuit Playground Express. And we have a huge community of makers and engineers as well with almost 30,000 Discord members, 1,500 GitHub repos and weekly live shows almost every single day. So we have a lot of insight into what makers and engineers are doing with our products and we're always so impressed with how creative they can be. I'm going to show you a demo using an Adafruit BrainCraft hat for Raspberry Pi and Microsoft Lobe. The BrainCraft hat fits on top of the Raspberry Pi 4 and makes it really easy to connect hardware and debug your machine learning projects. There's a 240 by 240 color display so you can see what the camera sees, which is great for vision projects. There's two microphones for audio input and then GPIO ports so you can connect things like relays, servos, LEDs, or other mechanical devices that you want to control from your Raspberry Pi. Microsoft Lobe is a free tool that you can use to create and train machine learning models that you can then deploy almost anywhere. This takes care of the hardest part of machine learning which is creating and training a new model. I've been playing with the idea of using a Raspberry Pi, the BrainCraft hat, and a Raspberry Pi camera to recognize these delicious baked goods from my local deli. Now these baked goods don't have QR codes or bar codes and so that's why using a camera with vision recognition would be an excellent way to identify and price each individual baked good. Let's show how easy it is to use Microsoft Lobe to train a new machine learning model. We're going to create a new project called the Lobe Bakery. Now it's time to import image data. Click on import and select your webcam. Now it's time to train the model on different images of baked goods. Let's start with the cinnamon wool. Place the object you want to train in front of the camera and select the label that you want for these images. Now take about 20 images of your baked good. You'll want different poses, angles, maybe flip it upside down. Okay, I've got about 20 images of this cinnamon wool. I'm going to continue doing this for each one of my baked goods. After I've verified that my model is correctly identifying all of my delicious baked goods, it's time to export that model. Go to the export tab and you can see all the options. You can create a web app. You can export it to TensorFlow, to JavaScript. You can even make your very own web server, web app, or run it on a mobile phone using iOS or Android. In our case, we want to export it to a TensorFlow Lite model file that we'll then copy over to our Raspberry Pi. Let's start by SSH'ing into the Raspberry Pi. Then CD into the directory where I've downloaded the software. Now you can run the basic prediction project that's written in Python. Because I've already deployed the model, it's going to immediately start doing predictions based on when the Raspberry Pi camera sees. To start, it sees nothing. But when I put a cinnamon roll in front, the text will update telling me the confidence and the label of the object detected. I can also try a cross fun or a bagel. Now, because we've deployed our machine learning model onto a Raspberry Pi, it means it's really easy for us to connect all sorts of other cool hardware. So I've got, in addition to the display, three LEDs are going to glow green when something is detected. I've got a speaker and some text-to-speech code that's going to speak out what's detected. And I've even got a receipt printer hooked up that'll print out the product and the price. So let's try it with the cross bun. Or my favorite, the cinnamon roll or the bagel. There you go. Thanks, Loeb. We sell the BrainCraft hat in the machine learning kit for Loeb at the Adafruit shop, and we've got tons of tutorials to get you started on your machine learning journey. Now that you've seen how easy it is, I can't wait to see what kind of creative projects you come up with. Thank you to Microsoft and Loeb for making machine learning training so easy. Now back to you, Kevin. Thank you, Lee Moore. I actually took a shot at building an Adafruit Loeb project of my own. The device that I was working on when you all first joined me was a little computer vision system built on an Adafruit Raspberry Pi Loeb kit running a Vision ML model trained with Microsoft Loeb. It will keep an eye on me when my monitor is engaged and remind me to get up and move around a little bit every 15 minutes or so. I started my engineering career over 30 years ago designing electronic control systems and writing embedded software. I'm just stunned by how capable these systems are today and how much I'm able to do just tinkering around in my spare time. Like I seriously just put this little device together in a couple of hours over the weekend. All right, and I want to thank everyone at Microsoft who helped us out with this, and then also... And the local bakery. Delicious. The approach that Microsoft is taking with AI machine learning because we have a lot of choices on who we work with and what we do. We really like the lines very closely with our values. And we also wanted to come up with a demo that could be relevant, could show how all these things can work together, how it could be machine learning on the edge. So that wasn't interconnected. It doesn't need to be either. And it was something that we could show. And as soon as you see it, you're like, oh, I get what this is now. And also very young people could help out with different parts of it. Not just the coding, but like the imaging capture and all that. So we have some more surprises ahead with machine learning and AI. But once again, thank you everyone who worked on Loeb and Microsoft. And thanks for including us. And they're a very cool and important event today. Yay. Next up. It was so tasty. Yeah, and we ate the props after this. I ate the evidence. So quick ate a box update. I've said this on a few shows, but just a bit of a reminder. So if you are getting an ate a box in Europe, that was your last one. We'll have an email out to you in the UK. They're not part of Europe anymore. I don't know if you heard. Yeah. And you'll get an email about it. We don't charge until we ship. So don't worry about that. We have just two people that were on gift subscriptions. They're getting those all the way to the end. We have to put pause on international shipping for ate a box for a while just because everything has changed recently. Don't worry. We're still doing it in the U.S. And that just means we can add more folks in the U.S. Yeah. And so please go to ateabox.com. Sign up. We'll be adding even more slots, but this will be for North America next up. Big news. Hackaday, Tindy, which are part of Supply Frame. Yes. We're sold to Siemens. So I have questions. You've got questions. And you might have questions about this. We're going to get answers. And so I reached out to the Siemens PR folks and they said, yeah, sure. Send your questions. Yeah. And just on a personal note, just so folks know, I founded Hackaday and I designed the logo over there and look at the site and all those things. And I have nothing to do with it now. And so obviously I have some like questions about the future because now my little skull kit is 17 years old. The site's 17 years old. Oh man. It can drive. And it can do all sorts of things. Oh boy. And I want to find out for the community. What does that mean for Tindy sellers? What does it mean for the editorial at Hackaday? What does it mean for the staff? And then also, you know, on a bigger picture thing, what does it mean in this industry consolidation that's going on with large entities? Now a lot of people don't know what Spliframe does. Basically it runs like fine chips. It's like an advertising company, essentially for chips. Yeah. And so they did a really good job maintaining Hackaday, giving it resources. Good job with Tindy. People were able to start small businesses. So if you have any questions that you want me to ask Siemens, email ptdatafruit.com. Folks have. And I think I got some good ones. But I also want to make sure that they let us all know because they bought a community. Hackaday.io is a community. Supercons community. All the things that we do with like Tindy, it's a community. So that's one of the things that I'm sure they know they bought a community. But I want to find out what it means to them and what it means to all of us. So send your questions my way. I'm going to be sending them over pretty soon. I think it's super cool that they're even, you know, they even replied back to my email. That's cool. Yeah. So we'll see how that goes. And I'll post them up on our blog soon. Yep. Okay. Collins Lab is something that we release every single day. You have something to look forward to pretty much every day. No matter how good or bad your day is. That's right. There's a Collins Labs note. So we're going to just play these back-to-back there a minute each. See you on the other side. The ESP32 S2 Rover is a low-power 2.4 GHz Wi-Fi module with a bunch of additional features in a compact RF shielded package. A couple of minutes with a hot air rework station will allow us to take a peek inside. And inside we find, that's right, more electronics. Arranged in what appears to be the aerial view of an office parking lot. Specifically, we can see clusters of passive components outlined by registration marks, the actual ESP32 S2 chip, its timing crystal, and finally the PS RAM and flash memory chips. If you need to locate a specific pin on a chip, you first start with pin number one and count up from there. To find that first pin, look for a marker on the chip's surface, often in the form of a dot. In the upper left-hand corner, or a U-shaped notch, or both, or a printed symbol, it does tend to vary. On top of that many chips have additional unrelated circular indentations, just to make things a bit more confusing. In any case, we have our dot. Pin one is always going to be to the left of that marker. And moving counterclockwise from there, the pin numbers always increase. So this 28 pin chip in a dual inline package counts to 14 while going down the left side, then jumps over to the right and counts up to 28. Often when something mysteriously stops working, a blown fuse is to blame. Fuses protect devices from too much current, bravely sacrificing themselves to keep your electronics safe. Fortunately, they're inexpensive and easy to replace. You can tell when a glass fuse needs replacing by looking to see if the inner wire conductor is broken. But ceramic fuses are a bit more opaque. You can always use a multimeter's continuity test to check the fuse. Remove the fuse from its original circuit, then set your multimeter to continuity beep mode and make sure it's working. Then connect one lead to each side of the fuse. If you don't hear a beep, that means the fuse is beep, so you should replace it. But if you do hear a tone, then this fuse ain't blown. Yeah, this one's still good. If you've ever put together a circuit to drive a solenoid, you may have noticed there's two essential parts. A big transistor that can drive the large amount of current and a diode. The transistor makes sense, but why do we need the diode? Well, if you look inside of a solenoid, you can see that it's made of many turns of coiled wire, just like an inductor, which is also made of many turns of coiled wire. And when you cut off current to an inductor, it throws a fit and generates a spike in voltage, which can be useful when constructing a voltage booster, but a spike like that from our solenoid could easily damage the driver and connected circuitry. That's where the diode comes into play. Adding a diode across the solenoid's leads prevents the voltage from getting too high, directing it away from the power rails, keeping our circuit nice and safe. Working with wireless electronics means thinking about antennas. Some electronics include antennas built in, but some like this Lora module need an external one added. You can buy an antenna, but you can also get by using a simple quarter wave monopole made with wire, snips, and a little math. First, find the wavelength lambda with this equation, where C is the speed of light about 300 million meters per second, and F is the frequency of the signal you're working with, in this case, 915 megahertz. We just need a quarter of that wavelength, so divide it by four. And the result is the length of our quarter wave monopole antenna. Cut that length in wire. Solder one end to your antenna feed, and you're ready to radio. All right, and other bits of time traveling. This is a cool video from Philby. This video explains why electronics could influence environmental sensors. No, environmental. Environmental sensors. Environmental can affect your sensors. That's right, I gotta reverse. The environment can affect your sensors. Not the electronic can affect your sensors, but that could happen. That could happen, too. Anyways, take it away. And just watch the video. Hey, remember this method for measuring Neopixel PWM timing? Watch this. Ah, chilled Neopixels. Notice the PWM timing. It's around 1.2 kilohertz. Warm them up a bit, and that number changes. Now it's around 1.3 kilohertz. We think of digital circuits as this very regimented thing, but really there can be analog influences behind the scenes. It could be temperature or supply voltage, barometric pressure, or ambient light. It's usually harmless, but there are edge cases. The Johnny Act computer had lights installed inside the cabinet because the vacuum tubes weren't reliable in the dark. Your Burning Man project that worked fine on the kitchen table but failed when you got out to the desert because you thought you didn't need level shifting. It's also why your smoke alarm always starts beeping at 3am because it's colder overnight and the battery voltage varies slightly with temperature. Okay, jobs.atafruit.com. It is a place where you can post your skills and get a job or if you're a cool company and you want to hire someone in the maker world, you can post your job there. You both. This week we have two. Manufacturing assistant full-time at Evil Med Scientist, Sunnyvale, California. They must be firing their cats. No, the cats are still working there. But they want a manufacturing assistant full-time. We know them. We like them. Lenore and Waddell are great. I would suggest working with them. And the cats. It is an in-person job there in Sunnyvale, California. And then the other one is a contract job at University of Massachusetts Dartmouth, full-time lecturer position in embedded systems. Oh, that could be fun. That could be super fun. So check that out. Jobs.atafruit.com. Lady Aida and I look at each job. We make sure it's legit and then we release it and then you can apply for it. Next up, Adafruit I.O. We have a very cool I.O. update. It is a preview of Whipper Snapper. Take it away, Brent. In the last video I showed Whipper Snapper, our IOT no-code platform with the Adafruit Funhouse. And I configured three different buttons. And if you press them, they show the status of the button. Now we're going to visualize it with an Adafruit I.O. dashboard. Each component on an Adafruit I.O. Whipper Snapper device is a feed on Adafruit I.O. So if we add a new block to the dashboard, let's say a gauge block, and we scroll down to where the Funhouse is and we click the select button. Next step. And it's only going from zero to one because it's a digital component and we make the block nice and wide. And we'll click create block and we'll move it up, make it a little bit larger. And then whenever I press the button, the gauge's value will change. And it will also be reflected on the device. Next up it's... Look at that. Python on hardware time. Yes. We have a newsletter. You can sign up for it at AdafruitDaily.com. And I'm going to show a little bit about it. I'm going to save this part for the end because I have a separate thing that I'm going to do with this. Right. We're going to skip to this part. Over on Tom's hardware, they covered the MicroPython and CircuitPython merge, which is kind of cool. We have more and more of MicroPython and CircuitPython. We're all caught up. Coming together. Yeah. Snake friends. This young person showed how to mix MicroPython and CircuitPython code in the same file using Raspberry Pi Pico. You can check out some of the Pimeroni CircuitPython they've baked in to their platform to tech libraries and their MicroPython helper library. As we talked about on show and tell, one of the new features we have is you can disable this CircuitPython USB devices in boot.py. So basically like in seven, it's easier and better to use it as like a keyboard or an HID device. This is really cool. Just make sure you know what you're doing with some of the stuff. And then you can see our Desk of Lady Aida coverage. And when we talked about the RP2040 Trinky, we'll have that out soon. And then do check out the giant amount of Python on Hardware News from Recap's Pycon. It's Scott hanging out with a purple snake and then a purple lady hanging out with a Scott snake. I thought this was kind of neat. Oh, guide in the middle. Guide in the middle. You're missing a snake. Where's your purple something or snake? I thought this was cool. Yeah, but I thought this image was neat. This is from the Python Software Foundation language. No real snakes were harmed in any of these photos. From the language, some of the lightning talks. So check that out. So we have all of those things. And you can get a recap from the DeepDive with Scott and many other things. So there is so many keyboard projects and so many different Python things. And then the creator of Python just did some recent interviews. We posted up that and there were some follow-up stories and we have those as well. So check this out. I guess one big headline or phrase is, believe it or not, from Hacker News. Oh, no, not the insight. Yeah. Well, so the quote is, Circuit Python is my go-to for teaching people how to program. And read the whole story, but you can start to see what we've been seeing because we pay very close attention to what the community says, why they like the stuff we do. And it's become the tool or the thing to get people started so quickly. And even for kind of a tough crowd, which I'd say Hacker News is, high price. So anyways, check that out. And check out all the news and more. We're almost up to 9,000 subscribers. So if you haven't, please sign up on aetherforddaily.com. One of the things we do is it's completely disconnected from our shopping site because we don't like when we go to shopping sites and then someone all of a sudden starts sending us newsletters. We do not like that. So you go to aetherforddaily.com. We'll never spam you and you get the newsletter. So the big news for this week is TI, who makes these calculators. This is a TI 84. Now in color, compared to the ones I remember. The one that's coming out has a fork of Circuit Python on it. And we were like, huh, that's interesting. And apparently a teacher already got it and they're like, yep. And they tweeted about it. And then we're like, that's interesting. We want to know more. A friend of ours, well friend now, chatted with TI and it was on their live chat and says, what are all the modules included with it? And they sent me a screenshot of their chat and I'm like, this is looking pretty good. It looks like this is real. A fork of Circuit Python is shipping on TI 84 calculators and all of them. Then they tweeted back at us and says, hi, our Python app on the TI 84 plus CE Python. Use Circuit Python with some modifications. The other components of the apps were developed by us, the TI 84 plus CE Python graphing calculators are coming soon in the US. And we'll be available for the back to school season. So the big news for us is we emailed with them and they said I can interview their developers. So I'm going to find out why they chose it, why they chose to have a fork of Circuit Python on there and more. Is this kind of big deal? It's a big deal. Yeah. So anyways, all right, open source hardware. You know, we do open source so much so that TI can come along, fork Circuit Python and put on their calculators. But we also do... Wait, did we end that Circuit Python? Yeah, that's it. Okay, great. That was it. Sorry. Oh, you know what? I was supposed to show the little thing at the end. Yes, it's not a big deal, but... Yeah, all right. I know protocols. Okay. Anyways, that's how you know the segment is over. Right. This segment now starts anew. Anew. So we have 2,482 guys. Yes. What's on the big board this week? Okay, so this week we've got a Neo Trinky case from Noah and Pedro. We'll have a video for that, I think, next week. We've got Catney published the guides for the iSport CQT Rotary Encoder. So that was a couple weeks ago, a new product. The Neo Key Trinky. She's working on the Rotary Trinky next. That'll be coming out soon. Dan ordered a guide about how to customize USB devices in Circuit Python so you can turn off the mass storage or REPL CDC connectivity. This is really handy for people making keyboards or user interface devices where they don't want the mass storage to show up because it can confuse people or they don't want people to mess with the code or if they don't want the REPL because they want only one USB serial port and they don't want it to be REPL connected. So basically you can now customize whether you have MIDI or HID or mass storage or REPL and Dan goes through that as well as what to do. If you accidentally turn everything off and now you're completely locked out of your device. So check out that guide. It's in 7.0, so it's very new right now. But if you have a device and you would like the Circuit Python you'd like to turn off certain USB descriptors. You can go check that out. I also got some updated guides for the MagTag and the ESP32 S2. Now with PrettyPan to get the PrettyPan stuff. We have that guide that Melissa wrote for how to put Blinka onto MicroPython so you can run Circuit Python libraries on a MicroPython device. We actually started Blinka with that. That was the original point of Blinka our Circuit Python libraries run on the Pi board. But since then it kind of ended up turning into a Linux implementation which is good. We went back, cleaned it up, made sure it still works on MicroPython and especially added the implementation for the Raspberry Pi Pico. Also Dylan wrote an awesome huge project on making an Adafruit IoT Hub with the FunHouse. So if you don't want to run Home Assistant you kind of want to make your own Home Assistant project. Check out that guide. She's got like a bunch of projects. Different boards that can connect to the FunHouse and then send data back and forth to it as like a hub. So it's like intense. So definitely like make a cup of tea and then tune in to that guide. We did all through. Okay. That's our guides. Tune in for more next week. Getting close to the 2500. Where are we at now? 2482. Oh yeah, we're definitely gonna hit it in the next couple of weeks. Getting close. All right, some New York City factory footage. Factory footage without some of the timeline lapse of what's going on across street. Disney's building something. Apparently now I'm because I got an update. The bees, because of this construction. There's the bees are moving around. Oh, the bees are related to the construction? Maybe, yeah. So I'll find out more about it. Okay, tell us about bees. All right, 3D printing is next. Yep. All right, we got two videos. We're gonna play them back to back. First is the FunHouse video that Pedro put together and then a speed up. See you on the other side. Hey, what's up folks? We're taking a look at the Adafruit FunHouse. It's a dev board that's designed for IoT and home automation projects. With a built-in display and sensors, you can easily make Wi-Fi projects in CircuitPython or Arduino. It features the ESP32S2, a TFT display, cap touch pad, sensors and a speaker buzzer. On the front of the board, there's a built-in humidity, barometric and temperature sensor so we can sense the environment around you. With onboard STEM-AQT, you can easily plug and play iSquared-C sensors to expand your projects. You can also connect relays and break-bean sensors using the 3-pin JST ports on the side. We 3D printed the stand with the Yellowbrick Road theme to compliment the amazing silkscreen from Phil B. With Adafruit IOT, you can create an IoT door alarm using a magnetic switch and get email notifications on your mobile device. Head over to circuitpython.org and get your FunHouse board ready to install CircuitPython. Click on the board and select your preferred language in the drop-down menu. Then click the download UF2 button. Double-press the reset button to get the board into the bootloader mode. The neopixels will flash and the display will show a friendly splash screen. Then just drag and drop the UF2 file onto the USB drive. The firmware will automatically install and restart the board. You can then toss any images, library files and your code onto the CircuitPy USB drive. Be sure to check out the FunHouse Learn Guides for project inspiration, documentation, and example code. CircuitPython makes it easy for folks who are just getting started with electronics and programming. So if you're looking for a way to automate your projects at home, we hope you're inspired to check out the Adafruit FunHouse in CircuitPython. Good every Wednesday, 3D Hangouts from Noah and Pedro. All right, lady, it is time. That's right. This week's on MPI. I'm brought to you by Digikey. I'm Adafruit. This is from Omron. That's right. What do they do? What do they make? What is the MPI? Okay, so Omron does a lot of automation and sensing. So a lot of times when you have sensors for robotics or automation or factories, it's going to be an Omron sensor. Like our pick and place and board stenciler and board placer, they all use a lot of Omron sensors. Desi, Omron siren. Every time we say Omron, make some noise. I know. We're going to do the party. It's over live in New York. It's in New York City. And there's alarms. But so this week, I saw this pop up on IonPI. And it's like, sometimes we have IonPI's that are like really like incredibly complicated, advanced, like single board computer, like machine learning, time of flight cameras. And sometimes it's like, here's a sensor that's just really useful. So this week's sensor is just really useful. So this is the B35WDB series. So let's go check it out. This is a like a break beam sensor. It's a diffuse infrared sensor that's just kind of really well made and has a distance range of, it says, you know, 550 millimeters, about half a meter. But you can actually kind of go up to 800 millimeters or about 0.8 meters, depending on the material that you're detecting. It doesn't do distance. It just does whether something is in the path of the beam. So it's a diffuse reflective sensor. Right now there's only one model. It's the NPM input. You see the distance is, you know, 550 super miniature. And it's got a nice mounting system, which I'll show in a bit. Using it's really easy. It's got three terminal connections, one power that wires, that powers the sensor, the LED and sensing circuit, then ground, which is, you know, the power and signal ground. And then there's a load output and you can see there's an NPN transistor. So you can sync, you know, I think probably about 100 milliamps or so through it. Not good for inductive loads, but you could use this to say, power a relay or a transistor that could control the relay or control the solenoid that you want to power. But for just like an LED indicator, you know, definitely this would be able to power that. So the distance, so in this case, you know, just sensing it with white paper, you'll see it's good from, you know, zero to close to, but not quite one meter. The reason they'll say, you know, 550 millimetres is because of the color and reflectivity. Since the sensor's interesting, apparently it can detect even clear materials, which is kind of neat. Some IR sensors don't work well with glass, but this can handle even transparent or translucent materials. The, you know, the document is really good. The CAD file has a lot of details. So you'll see here, something interesting, you know, it's small. It's like an inch or so wide. And then the mounting holes, they go both ways, both lateral and vertical. So you can kind of mount it any which way you like, which is kind of sweet. And on the bottom, there's a plug and there's a cable that you can get. It's got a JST. I don't know if it's exact. Let me go to that. Yeah. It's the EE5002 cables. This is a pre-made cable assembly. You plug it in or, you know, you can just make your own cable. This is the GHR series. It's a little latch plug-in cable. Your choice, either way, you just plug it to the bottom and you're ready to go. Available on Digi-Key because that's this segment, NPI, all the new things on Digi-Key. You can get this on the website. The short URL is digikey.com for its last short slash td0dh439 or you can search for it with the product number up at the top there. Yeah. And let's show this off. Yeah. So I'll show this off. So actually I opened this, this one up. Usually it has a very nice cover, which I, it's actually a very nice sealed cover. And I wanted to show it. So you can actually even see the transmission diode here and then there's the receiving diode and then there's like a little bridge in the between. And these are tuned to be, you know, to not interfere with each other. And then, you know, when I put my hand in front, you can see this indicator LED, which I've wired to the output, turns on. It's really simple. But yeah, what I really liked about this is you see that there's these mounting holes. And then if you turn it, there's another set of mounting holes. They did like this cool, like either way, you know, however you want to connect it, very compact, very easy to use. And a longer distance than most proximity sensors, right? A lot of sensors, they're good for, you know, maybe 200 millimeters or so. So I was impressed that this was for not too much money, you get something that could go up to, you know, half a meter or more. But a very simple, very effective sensor. Tell you, you really don't want a, an object sensor that's flaky. Like it has to be very reliable, because if you mess up even once, you might, that, you know, an object might go past your conveyor belt, or you might not hit the safety interlock. So even though it's like a very simple sensing element, you really want it to do a very good job in all sorts of light conditions, in all sorts of, you know, environmental conditions. You saw that video earlier about how temperature and humidity can affect your sensing elements. But Omron has been really doing this for decades. It's trustworthy. I mean, like, you can use this. It's reliable. It's high quality. It's going to do the job. It's going to do it right every single time. All right. And that is this week's ION MPI, Kentucky and Adafruit. Okay. Before we get to new products, I just want to remind everybody, we have this code just for this hour. So start loading up stuff in the cart and get ready to check out. We're back to coding. Let's do this. Ready? Yeah. All right. The first one is it come in soon. Come in soon. Yeah. Do we get the POE plus hat? This is the new POE hat from Raspberry Pi. I think we even have some of the old version. This version, it's like much slimmer. It's got this cool lateral transformer. I think they've improved the design even a little bit. I still got that fan in the middle. It's a pretty sweet POE hat. They're non-stock. Nobody has been stocked because they are still being manufactured. Yes. Please be careful because a lot of websites will let you back order stuff and pay for it, but they don't have it. So just sign up on our site. We'll let you know. You'll get an email and then when you buy it, it's actually because you're going to get it shipped immediately. It's the real thing. Here we have it. So it lets you basically, you have a Raspberry Pi 3B plus or a 4. You plug this in and then you can power the Raspberry Pi through the ethernet port if you have a POE hub, which a lot of people do. Yeah. Next up. Okay. Next up is this really adorable woven cable. We have had this cable with a micro-B connector on the end. Now we have it with a USB-C connector on the end. So you have a USB-A on one side, USB-C on the other. It's two meters long. It's really cool. It's got this Blinka pink and purple color way. I don't know. It's a very nice cable. What I like about this cable is it stands out against all your other cables, which are all black plastic. All right. Next up. Next up, we have an 80 watt soldering station from Atten. I really like these quality soldering stations. This one has a bunch of stuff built in in addition to the soldering iron and 80 watt, which is connected in the adjustable dial for temperature and the digital temperature readout. It also got the brass sponge. All y'all like it. There's little holders on the side. There's four slots or five slots or four HACCO compatible tips. And it also has a solder roll holder. So it's kind of got everything and it heats up super, super fast. So if you want a soldering iron that you turn it on and it's like instantly ready to go and adjustable temperature, these are very high quality. And of course, you can change out the tips quite easily. Next up. Next up, to go with your PoE hat, here is a terminal block to Ethernet jack. We have these with the opposite connectivity, the plug type. And some people are like, oh, I really like that, but I want the jack type. So let me grab it one moment. I will show it on the overhead just because it's got it. It's got an interesting thing going on here. So Ethernet, it's actually not Ethernet. It's RJ45. You can use it for Ethernet. You can use it for anything else. In fact, I wouldn't recommend it necessarily if you're using it for Ethernet because you're going to have the wires come out. But if you want to use Ethernet cable, Cat5, Cat6 cable for sensors for making your I2C cables really long for whatever analog signals, as long as you're cool with the cable being very long. And this has a nice, pluggable terminal block. So this seats in very nicely, but you can easily unplug it if you need to disconnect the wiring from the cable for some reason. And we have these also in the plug versions. This is the socket, RJ45. Next up, we have this very tall case. I like this case. It's some Andes. They make these really beautiful cases. But what I like in particular about this one is how tall it is because you can fit a lot of stuff in here. And it's got some nice vents as well. So hold on. We don't stock every case. Believe me, there's interesting cases. So this is a good one to get. Yeah. It's got the clear top. The top is acrylic. So you don't have to worry about, you know, Wi-Fi signal can come out this way. It's got slots on the bottom, mounting holes over here. You can get to your USB, sorry, the microSD slot. This is a holes for the power LEDs, which are on right now. Of course, the Pi 4 audio and power and the two HDMI outputs. And then, of course, the USB ethernet. So it's all good. I mean, this one should be great for your PoE hat, right? Because you can put that in here and you have room for hats or electronics inside. It's extra tall, but you still get that protective cover. But you can see through and see how your display is looking, your OLED, ink, whatever. I don't know. I really like it. It's a very nice case made out of aluminum and clear acrylic. Next up. Next up, finally from Nordic. We've been waiting for this. To get this, we got this. So from Nordic, we now have the Thingy 91. So we've got the NRF 91 feather, but I actually kind of liked their dev kit for this because it's kind of cool. It's got this rubber case. And let's go over it. I'll show it off. You have this rubbery case, which I can extract this. It's got this plastic... Hold on. It's not that hard to remove. It's just hard to do it on camera. We're tired. Well, no, it's just like... We're also tired. Yeah, a little bit. So the NRF 91, this is their... I think it's a Cortex M4 dual core with a cellular modem inside LTE modem. This is a SIM card slot. I think it comes with a SIM card as well, which you can activate. This is of course data. It's not... There's no audio that I can see anywhere here. But for data, it's great. There's an antenna. This is the NRF 52. I believe there's an NRF 52 on here as well somewhere that you can program to control. This is NFC to do the NFC pairing for the Bluetooth. I believe that's correct. Power switch. And then there's a bunch of sensors, although I didn't think to open this ahead of time. So let me see if I can... Yeah, there's the... I think this is the Bluetooth antenna. Hold on. I'll do something risky. I want to try to open this. This is risky. This is very risky. This is probably a big mistake on my part. You're using a pen, Sam. Yeah, I know. Shoot. Look at this. This is a live or anything. I know. Okay. Wait, hold on. I have even the worst tool in my screwdriver set. Look, it's worth it. Welcome to bad ideas. This is bad ideas. Oh my God. It's connected on both sides. Okay, hold on. Okay. All right. So on the opposite side... Yes, we've got... I think it looks like a BME 280 or BME 680. This is the back of the antenna. USB power battery. So it's got a rechargeable battery, of course. And then more sensors. Probably like accelerometers and stuff. Looks like there's two RGB LEDs over here as well. So basically a ton of circuitry. So when Lady Aida takes it away, she's using her supervision on her eyes to figure this out. But we can also zoom in. I can zoom in. I think this is a... This looks like a light sensor as well. And then yeah, these are probably accelerometer, gyro type things. Environmental sensing. And then this looks like NFC pairing or something like that. So yeah, this is probably the NRF 52, I think 840, with a Bluetooth antenna and all the circuitry. So kind of... It's an all-in-one kit, which I really like. And then here's the IMEI for the device as well. All right. So look, you want to do cellular stuff? I mean, yes, the feather is really good, but this is their official supported DevKit for the NRF 91. Next up. Okay. Next up. Ooh, this is my favorite. So we finally got these two as well. This is the PPK 2. So this is the Power Profiler Kit. And this is something that Nordic designed in-house for measuring the power of their... We like this a lot. Cellular and Bluetooth boards. But then they were like, wow, this is really handy. We should sell this as a standalone thing. So this is like... It's like about a hundred bucks. This is the same capability of like, believe me, $1,000 power monitors. This is an excellent power monitor. We have to use all of them. Well, the more expensive ones too. Yes. And I have the expensive ones, and they're great. But this is like... If you are just doing basic battery, zero to five volt power analysis for your ESP32 or your Wi-Fi or cellular or your Bluetooth, the PPK is a great deal because it comes with everything. It has a little built-in ammeter. It also has a built-in power supply. Like, it can supply the current to your device under test. And it comes with software Mac, Windows, and Linux. And it works really wonderfully. I used it to do the MAG tag. We did an IonMPI analysis. We did an IonMPI on it. Yeah, we liked it so much that we wanted to stock it. This is like... Yeah, this is a great deal. If you're doing anything with low power, stop guessing about what your low power is. Stop trying to use a multimeter. Just grab this because you'll be able to actually do analysis on spiky power transmission for use cases. Next up. Next up. Will this cure all of your problems? Yes. Yeah, probably. It'll cure that not having a cap-pog key cap problem. Yeah. So check this out. All right. So this is exactly what you think. It's a key cap for your Cherry MX keys. And it's got super squishy silicone toe beans. These are not translucent toe beans. We do have one that has translucent ones. These are pink, which he doesn't love. It's the Adafruit pink and black. And then you zoom down. I'll zoom in. I'll zoom in. Okay. So yeah, this is plugging on to any Cherry MX or compatible crossbar. Basically any mechanical keyboard. And then it's squishy and these toe beans are extremely enjoyable to pet or squish. And if you have a cat, you know how much fun it is to do. When I can do it, even if you're casting around. Yeah. Okay. Next up. Start of the show tonight besides you, Lady, and our community, our customers, and our team. Is NeoKey 1x4 QT? So how do I explain it? Basically you want to add mechanical keys to your project. You don't want a time. You maybe only want four key switches. You want new pixels with them, but you don't want to do all of the wiring for it. You want to have it over I squared C. And maybe also want to chain it with more of them. You can actually connect multiple of these. So this is a way of very quickly adding four mechanical keys with new pixels to any board. It has a C-style microcontroller on the underside, which does the I squared C to NeoPixel and key switch conversions. So here I've got it. Okay, I got to zoom back out. I've got my QT Pi here. So it's just something that has an I squared C connection. And this is running Arduino, but it works also with circuit Python just fine or Python to use with a Raspberry Pi or what have you. And each key has a NeoPixel underneath. And this demo, just when you press it, it does a little NeoPixel color swirl. So that's the demo. And you can have multiple keys pressed at a time. They have Kail sockets. So these are socketed so you can use any Cherry MX compatible key. This is, I think, Cherry Black or Kail Black, I don't remember. And then, of course, you put your favorite key caps. Maybe it's a little kitten key cap or maybe it's these translucent ones so you get the glow through. And you basically have a very easy way to add four key caps. Okay, so key switches to your project. And then the I squared C comes in. This is the chip that handles all of the key presses and the NeoPixel stuff. And there's address jumpers here. So you can close these, which allow you to connect multiple boards to one I squared C port. So you can have up to 16 of these on one I squared C bus. So if you're not enough to make a full 108 keyboard, we're making like a macro pad. And you just want to really quickly get a bunch of keys together without much soldering. You just plug in your favorite mechanical key. And you have plenty of mounting hole options. So you've got four mounting holes on the corner. You can also plug into a breadboard if you don't want to use these cables for easy perfboarding. I think it's like a fun way to get mechanical keys into your project without any key matrix handling, without NeoPixel handling. It's all done for you. Okay, don't forget because this code is going to go away soon. MS build, put all that stuff in the cart you just saw. Check out 10% off on each tool tonight. Okay, let's do some top secret. But while we're doing top secret, load up your questions over on Discord. I have a few ready to go, but let's do some top secret later. Yes, from the vault. All right, so out of the things that are top secret this week, do you want to show the SPI friend? Do you want to show the STEM thing? Do you want to show the RP2040 stuff? Do you want to show... Well, let's do this one. This is... Okay, you just emailed me one morning. He said, we should make an ink trinket. So I just pulled together. Let's show the first video, the SPI 2040. I think that because I'm about to... We also have this slider snail. Wow, wow. Yeah, okay, so let's do the RP2040. Yeah, the first video. Or do you want to show all of them or just one? I'm not asking which ones are the most important for you. Just show the first two. All right, first half. All right, lady, what is this? Hey, I'm working on my STEMF friend. I've updated this board. If you remember, this was a SAMD21 with a display to like do iSquirt scene analog stuff helping. And I'm updating it to an RP2040, but you'll notice the display is a little slow. And if you look on the oscilloscope, it's only transmitting like one byte every, you know, couple microseconds. So what I'm doing is I'm upgrading the Arduino core from fellow Hauer to add faster SPI to do block writes instead of individual writes. So if I reset my board, and then I load on, I already pre-compiled this, my fast SPI, you'll see, boom, still fast. And then on the oscilloscope, it's writing out big chunks at a time. So it's like 10 times faster. Awesome. Faster screen updates, more data. All right, Lady, what is this? Hey, for the iSquirt C STEMF friend that I've been working on, it's got this 240 by 240 screen. And I thought, maybe it could be really useful also as a serial port monitor. So I wrote a little bit of auto bot detection code. So now if I connect this up to my GPS module, you'll see it automatically detects it 9600 bot. And it actually like reads the data and displays up to the buffer with this nice scrolling. The scrolling is harder than it seems. I have to actually make a frame buffer for the entire display and then blit it out constantly. It's about like 20 frames per second. But it's quite nice. It has a nice scrolling effect. And it would be a great debugging tool for say a GPS or maybe a Raspberry Pi. This works as well with auto bot detection. It's kind of cool. So I don't have to enter in the bot rate. That's not a secret. Okay, let's get to some questions. Back in the vault. Yeah. You secret stuff. They're very secret. Back to the hardware vision too. All right. Questions. The questions that I have lined up. Lady at it. Yeah. Get through these. Oh, we got a bunch. Yeah, we'll get through these really fast. We're going to speed round it. Are you ready? Okay. How do you feel about using fritzing application to map out a project? Yeah. It's a great idea to do it. It can really help you visualize your project. Let me tell you something. Don't worry about the tools you use. If it works for you, it works for you. I think in the past people have said this is the only way to do it. The term is gatekeeping. Try these apps. Fritzing is free. Try it out. If it works for you, great. I know folks that still use PowerPoint as a way to do a bunch of workflow stuff and designing a project when there are other things that have come along, but they really know that tool. Next up. Are you going to still assemble a friend and release a code and make it? Yes. Yeah, it's a future product. That's right. But when exactly? Well, you had to go through a revision. Okay. With all the talk of rotary encoders, do you know what the spinner controls were for Tempest and what baud rate they might be needed? I have no idea, but I bet there's a community of people who know. Yeah, there's a Tempest community. This is a pretty long one, so they might need to post in the forums. I have an HCSRO4 ultrasonic sender on my Raspberry Pi Pico board connected to the 4-pin and the ground pins of VBUS. I would like to connect the Max 98, 3, 5, 7, 8, 3, 1, 0 AM. I think this project, plus it's in the forum. Because it sounds like there's a lot going on there. There's a lot more after that. And you'll want to post maybe a diagram, maybe use fritzing so we can see what you're doing and what your actual question is. And how many things can the loop kit with Raspberry Pi set up to recognize? Now, here's the thing. It can recognize lots of different things, but only one thing at a time. So you can't put a bagel and a cement roll underneath and have it get both at the same time. Not yet. Not yet. But you just do one thing at a time and that was great for our demo. Next up, is there any Pi hat to provide internet to a Pi 4 using GSM Basem card? I think there probably are. I would look for like a cellular hat and there's probably someone who's designed one. Okay, more of a philosophical question. Where do you think ARM is going to be in five years? I think there are ARM chips everywhere. I mean, billions of chips. Why do you think they're so popular? You know, very low power, easy to license. I was going to say the ease of licensing. The ease of licensing, you know, they just are a little bit better than the 8051, but, you know, people are still using 8051s. Okay, next up. How can supply frame be worth 700 million? Well, it might not be a cash buy. Siemens might be giving them stock or something like that, but that is that is the price. And if they earned around 70 million revenue last year or projected for this year, which was in the press release, usually software startups are 10x, 70x10 is 700 million. A lot of people don't know that they do fine ships and that's a, it's a business that's an advertising model and it's a software company. So that's probably why you're seeing that high price. Also, there's a ton of capital out there right now. People want to spend this money and the prices probably went up for all these startups. But it's like 10 years old, so it's not exactly a startup. Okay, I already answered the low-bit one. Is there an option if I'm interested in recreating a piano keyboard? Oh, for Loeb? No, that wouldn't work out quite yet. I think that's the question because you would have to try to map all these things. You could do different little pianos underneath. Next up, the NRF PPK comes with a few cables. Can you make a cable kit for the PPK2, a four-pin out-to-punt connector, to batter JST for connecting a feather, a four-pin out-to-punt connector, also eligible to jump a wire? We have all the parts in the store for you to make any kind of custom cable. You might have to solder it exactly the way you want. But we have Dupont to alligator clip and we have JST connectors in the shop. So yeah, you can definitely make it happen. So folks were saying maybe fritzing is fee-based. I thought maybe there was a donate button. It's not. Well, look, if you want to donate to support it, go for it, but you don't have to pay for fritzing. It's free. Yeah, but we've donated to fritzing. Yeah, we did. If you want to start the project. Next, have you seen my project for trying to turn a defective slider trinket into OLED trinket and is a real OLED trinket in the works? No current OLED trinket design, but publish your project. Sounds cool. Okay. Any update on the click wheel you're working on? Yeah, I mean, we're waiting for the parts to come in. And yeah, the fritzing version 0.96 was released February 22nd, 2021. We put it up on the blog. The modern binaries are paid. We should use a previous one or pay. I haven't updated fritzing in like 10 years. One way to look at it is if you want to support open source software where they have a pay model, I mean, I'm sure you can also compile from source if it's still open source. But if you want to support an effort, pay the money. If it's a one-time fee, it's probably not much, and it's worth it. Yeah, someone says it's like a $7 one-time donation. I'm still running the same 9.4 from a decade ago. Okay, and then I have a question about the Raspberry Pi IO board in order for the run RTC to bring the board up. Does it have to be at a full 12-volt DC supply at all times or just give it 5 volts to power the connectors? I don't. I didn't manufacture that board, so I don't know. So I think what you are best off doing is contacting Raspberry Pi IO because like they support the hardware. I don't want to give you the wrong answer and then something bad happens. So contact them and they'll tell you the exact power requirements for the hardware. Except are you back up to speed? Any problem with getting chips? Yes, but we've figured out different products, board revisions. We also saw this coming and we had a pretty good supply. Kitty cap. You can't just order anything you want and get any chip you want right now, but we're doing okay. We're navigating it. We'll see how it goes. Next up, how could I connect a Raspberry Pi to... What is this? I don't know what that is. I don't know what type of machine that is. Okay. And then here is I think the definitive answer. Current fritzing is pay for pre-compiled or download the source and build your own. Oh, that's fair. Okay. There you go. And I think those are all... If you're young and you don't have any... There's people who are like, I have no credit card because I'm not old enough to own a credit card. If it's seven bucks, please consider supporting it. Support it or you can always download the previous versions. They're on the internet. Okay. And I think we got through all the questions across all the different chats. Good work, Lady, at a good work community. Okay. Thanks for that. Hang out in Discord. You can continue to ask questions and more. That's why we're there. I want to say thank you once again to everyone at Microsoft and the Loeb team who helped us do this cool project and it was in the keynote. And of course, thank you so much, everyone, in the Adafruit community, all of the Adafruit team members. Thank you to Kara, who's behind the scenes site and Adafruit Slack. Thank you all the folks that are in the chats, the CircuitPython community. It feels really good to be back. Thank you so much for supporting us over the last year. Don't forget until I get home and I turn off the code, it is Ms. Bill, 10% off for now and all the things that are in stock and eligible for discounts. Please check that out. And don't forget, if you're ordering stuff, Monday is a holiday, so there might be a slight delay on some things. But we have all sorts of warnings and everything all over our site even the outbound emails say it. So, y'all are cool with that stuff. And we'll see you next week. Here is your moment of zener. Bye, everybody.
