 live 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. We're here inside the Flying Toasters. We're here broadcasting live from downtown Manhattan in the Secret Aida Food Headquarters. We design many of the beautiful electronics that you know and love, but for the next hour we're going to be going through all the news, videos, products, demos, and more. We have a lot of top secret tonight because we've been holding them in. Yeah we had yeah that's how it goes now. We're working on a lot of hardware so it bunches up. All right so let's kick it. What's on tonight's show, Mr. Lady Aida? Tonight's show the code is rpthinkink 10% off in Aida Fruit Store. All the way up to like 59 p.m eastern time or when I remember to turn the code off. User to lose it. Anything in stock 10% off in Aida Fruit Store. We'll talk about our live shows including so and tell which you just did. Thank you, Liz and Erin for hosting that. A little bit of recap of Desk of Lady Aida including my great search. We'll play JP's product pick of the week. Time travel. Got a little cool thing from an Aida Fruit team member that I'm going to post up on our blog and on video. Some advanced manufacturing. Made in New York City factory footage. 3D printing. Eye on MPI. Brought to you by Aida Fruit and DigiKey. Top secret that's the big chunky one. We're going to do some new products. Can I answer your questions? We're going to do all that and more. Don't forget we answer the questions on discord.aidefruit.it slash discord or discord.gg slash Aida Fruit. That is what we call Ask an Engineer show this week. And we'll talk about what these toasters are and more but this is a live feed coming off a microcontroller right now. This second. This second right now. Can I just press the button? Press the button. No signal. There it is. Hold it down. What'll happen if I hold it down? It'll stay in the signal for a while. Oh yeah? Yeah. So we'll talk about this. It's a big deal because you can do stuff like this with a microcontroller. So cool. And we'll talk about the show in a minute. But this is me. We're able to do a lot of cool stuff that seemed impossible just a few months ago. We are back on our bullshit. That's right. Okay. So the code is RPT, kink kink. RP think kink. Irpus kink kink. Yeah. Rumpelstiltskin. RP think kink. You get free stuff. Maybe. Maybe. Oh yeah. Not that micro bit. We're done with the micro bit. Yeah, but it's a cool video. It's on the truck. Yeah. We got a purple pack and stock. They're back. The freebies that people love. $99 or more. You get a free promo proto, half size, breadboard, PCB to make your project permanent. And then $149 or more. You get a pink KB2040. It's our RP2048 dev board with STEMIQT, cast-slided pads, USB Type-C. It's pro micro pinout compatible, so it's a great update to many projects. UPS ground, free shipping when you order $199 or more. And not a micro bit. Circuit Playground Express. We got more in stock. The chip shortage is solely ending. Our favorite microcontroller board is free when you order $299 or more. It's got a SAMD21, two buttons, piezo, lots of capacitive touchpads, neopixels, and more. Yeah. For the chip shortage, it's the beginning of the end, not the end of the beginning. I think that makes sense. Yeah. We do live shows. And this week, Liz and Karen hosted it. Thank you so much. On the show and tell, you know, I'm not supposed to have favorites. However, I'm just going to go over some of the things that wasn't shown on tell. So please watch it. It's on wherever you watch our videos. So we had the Feather RP 2040 DVI showoff demo from Phil B, who worked on a lot of this. Cool. Scott Schitt, some of the DVI work that he's working on with Circuit Python. That means you can do things like go online with it, display text. Really neat. Mark Schitt's a GIF work, so you can just kind of pump out the animated GIFs to display. A portal gun. Kevin was live from an event show, just like really cool digikey tank. Taba showed the thing that we wanted to build. Like it's amazing. It's a video synth, like triangles and everything. And Todd just mentioned this in the chat, but I think it's worth mentioning too is one of the neat things about doing video stuff on a microcontroller like this, it's instant. You just don't wait. Like you turn it on and it's on. Yeah. Like, I think we've all waited forever just watching these. We've watched a bunch of video synths and they're all really cool. They're fine. They use Raspberry Pi. And so like you're waiting like a minute for it to boot and you're like, is it working? And most of the time, you know, you're tweaking stuff and it doesn't. And so you're like, oh, you just have to wait like a couple minutes each time. I really like the idea of like fast iterations with video. And then, you know, keeping with the tank theme, DJ Demchant off. A really neat tank, but it's building to explore the underground sewer system in his Florida home because the houses are built on concrete. And if you get a plumber, they want to charge you a lot. So why not build your own sewer bot? So I thought that was kind of cool. So we do show until every single week, some 30 p.m. Eastern time. We also do a show called Desk of Lady Eda and we do it in two parts this week. Part one, what did you show? Okay, for this lady, I showed off the Think, Inc. Feather, which is, of course, this week's new product. I also showed off a bunch of, sorry, I showed off U2IF, which is a way to, but was it this week? We've got a lot of speaks. Maybe this is this week. U2IF, which lets you program and control feather boards through USB. And so I was actually showing the Think, Inc. Feather warning off of Steve Python. I also showed off a new design, which is a prop maker, a feather wing. This is Dan's idea. So it has an accelerometer and servo and I2S output and neopixel driver. So good for props. And we do a segment called The Great Church, where you help people find the things they need on digikey.com. And then this week, you did what? Oh, I remember. Okay. So I was doing USB-C and power delivery USB-C. And for the board and we have it in the, it's not out yet, top secret section. I needed a regulator that would give you 3.3 volts, even if I had 20 volt power coming out of the micro controller. So sorry, the USB-C port, because USB-C power delivery can go from five volts up to 20. But the chip still needs 3 volts regulated output. So searching for LDOs is like a classic, you know, 5% of the time that's what you're doing on digikey. And I go through a lot of the settings and we found a lot of good options. All right. Then on Tuesdays, we have JP's product pick of the week. Here's this week's highlight. This is it. This is the product pick of the week. This week it is the Itsy Bitsy NRF 52 840 bolted to the side here. I'm just running a ground and one input pin to the switch contacts there. When I am listening to music on my phone and then I suddenly need to pay attention to something, this is programmed to act as consumer control over Bluetooth LE to the phone. Right. So you're rocking out to your tunes and then someone needs your attention. Something needs your attention. Boom! Hit the big button. That just sent Bluetooth radio wave-youles across the ether into the phone. Watch the play button there. It's playing. It's pausing. It's the Itsy Bitsy NRF 52 840. And on Thursday, JP's workshop and Friday, deep dive with Tim. All right, time travel. I got one little news item. I'm going to try to do this more and more and more. So a lot of folks at Adafruit are artists, they're musicians, they're writers. And so I'm always saying like, hey, if you have a book or something, I'll put it up on the blog. A lot of times people ask like, oh, what are the people at Adafruit? What music do they listen to? I'm sure they're like cool, cool weirdoes. Cool weirdoes. Yeah. And so this one is from Olivia and she has a couple of books coming out. And one is called Black Mask, a novel. Back Mask. What, like Back Mask, sorry. A novel. And the other one, and let me go to the Lockdown Laureate. Yeah, I like Lockdown Laureate. So it's a bunch of stories about doing stuff over the lockdown. So let me go to that. So I put all this on the site on our blog. So you can see Back Mask and Lockdown Laureate. And if you want to read about these, one is more of a, well, they're science fiction-y. But if you want to support an independent author, I'm going to buy a copy and just read one of the things that one of our folks make. One of our team members is an album, probably familiar with some of the music. So this is a book. And it's on our website. So let's take it out. Yeah. All right. Next up, lady, let's do some Python on hardware. All right. This week in Python on hardware land, kind of a big deal, I guess, depending on what you think a big deal is in the world of electronics. So Sony, they were making the Raspberry Pis in the UK. And they still do. They still do. And they make some in Japan. Yeah. And so this announcement is Sony backs Raspberry Pi with funding and access to AI chips. So basically, the way I'm reading this is Sony's investing in Raspberry Pi at the valuation of $500 million. That's what Raspberry Pi, not the foundation. This is the commercial trading company. And what it looks like they're doing is saying, hey, like, we're going to, you know, make Raspberry Pis, but we want to make sure there is AI chips on the edge. So a lot of the uses for Raspberry Pi is for commercial uses. Yeah. So people want to use a AI for voice recognition or face recognition without connecting to the internet or without needing internet control. So so many people use Raspberry Pi for digital signage or like entry computers or, you know, whatever. A lot of products use them. So it will be interesting to see Sony investing is really smart because of course, if they're manufacturing, they want to see Raspberry Pi succeed, but they also have a deep insight into the Raspberry Pi manufacturing and distribution. And like I said, they manufacture in Wales. They, I think they manufacture in Japan as well. Yeah. And one little bit that I thought that's interesting. It says in a typical year, roughly 70% of the sales now come from commercial customers, betting it in products and factories or consumer devices. So Raspberry Pi, the commercial company, 70% going to industry. And you know, there is a shortage of Raspberry Pi's. Yeah. I think we're one of the few companies that's figured out a solution that you're not going to please everybody all the time. We can please some of the people some of the time. And we're getting, you can look on like our PI locator on Twitter. People are getting Raspberry Pi's from us. Absolutely. You can always, you know, find people who are buying them, put them on eBay for like $200, but we're not interested. But they are becoming more available. And of course, the compute modules are very popular with industry, I mean, that's they clearly they designed it for industry customers. Yeah. And so CNBC has overview article, they dig into a little bit more of the finances and like what this could mean the specific chip and what they're doing with education and more. So check it out. It's interesting as far as like what's going on in the electronics world in general. So Raspberry Pi and amount of funding. So before they got funding on our evaluation of 500 million, so you figure like 45 million or something, probably this round is probably the same too. So yeah, yeah. So maybe maybe let's be like really conservative. Like let's say it's like $60 million altogether all the funding. Yeah. So it gives them a good runway to beef up production, hire more people, do a lot more stuff. Arduino last late last year, 30 something million in funding. And then they have a pro line. And that looks like the direction they're going. They're going to the enterprise. Commercial. What? Yeah. So like that seems to be their focus as well. And then you have Particle. I think they haven't been in the news for funding recently. I don't know if they're going for it right now. And then there's like other maker maker as companies from the past that that took on funding. There was little bits. That's now part of Sphero. And then there was MakerBot and then eventually went to Stratasys. So I don't have time to do like a big maker business overview or like all these players. Someone else should do it. It's one of those things where like, I think when you're doing the business of hardware, it's really hard to write about it. Plus I'll say this like back in the day or even now anytime. So I have the article about Arduino like over 10 years ago on Make. Now anytime if I write about Arduino, you know, some crank will say, oh, you're just, you're writing about it because you're, you know, you want to take over their business or you're just nutty people online. And so you can't, it's hard to write about things if you're in the same business. So I always put our disclosures and everything that we do. But it's an interesting time. There's more investment going into hardware. A good example was today with these RP2040 chips were doing video out. Like this is like really intense stuff that you can do. So yay, I'm happy to see Raspberry Pi get a new round of funding because the RP2040 has been something that's really helped us quite a bit, especially during the chip shortage. And hopefully they dump more resources in the stuff like this. Yeah, really, really like that. More Python on hardware. So the other thing, PyCon is coming up next week. Check out our extensive posts. Katnil will be there. Jep Miller will be there. Please go say hi and meet with them. Also, if you're attending, like Katnil know ahead of time on the Discord channel, and they can get you set up for if you want to do the sprints and things like that. So that is this week's hardware news. Don't forget, you can get this newsletter every single week, delivered to your mailbox from Adafürk Daily. Go to AdafürkDailyCup.com, sign up. Okay, let's do some open source hardware stuff, lady. We're an open source hardware company because that's what we like to do. And we have a bunch of guides. Yes. Thousands. Let's check out the guides. Okay. So Philby updated the Pico Arduino DVI library. Oh, can you click on it, sweetie? You can click on it now. So good examples. I'm clicky. And the screen savers. Yeah. So the new thing is screen saver demos. So we've got slowly. Oh, online. Yeah, you're online, but it's just, it's okay. So we've got a logo bounce, and this is the DVI. And this is actually 640 by 480 because it's actually writing pixels at the time of TV. Flying toasters, which you saw, you know, sprite based toaster animation, and aquarium, another classic after dark one, which is a lot of people's favorites. And then TV host, which does drawing like the person is a sprite, but the background is actually drawn live. So he actually does the math. And that's why, and you can have it like do something different forever, but the person graphics is what you have as a sprite. And thanks to JP for dressing up because I don't have a tie. Yeah, Laura was going to do it. We're like, oh, you know, like to do it right, we have to do a tie and everything. Yeah. Okay. Yeah, someone can make, in the chat, they're like, can I get a start at Starfield? Code it? You can do it. Absolutely. You can do it. There's tutorials and everything. Okay. So let's go back to the guides. Okay. Blinka, Circuit Python, oh yeah, Circuit Python libraries. Dan updated that and wrote some text. The ADT7410 breakout has been revised. It's now STEMIQT compatible. And I don't remember what happened with the Raspberry Pi camera timelapse. And then Ketney wept up the Feather RP2040 with RFM69. The Feather RP2040, RFM9X is coming next. And then Liz did a guide on using the Circuit Python. We classic controller. She wrote a library and is a tutorial on how to use it. All right. And then just a little side note, because we looked at this today, I thought this was, I didn't, you know, I'm not doing the whole segment on the show. But Washington posted an article about where Google is scraping data and make their large language models and AI and all this stuff. And I thought it was interesting because the number one site was Washington Post, well, you know, maybe, but number 15 was Instructables. And that's interesting to us because Instructables, what you know, well, we have history with them too. You know, we've done stuff. It's kind of where you started putting your how-tos and guides on online when we started Adafruit. I won a lot of contests. You won a lot of contests, in fact. And they told me I can't. You can't. You're a pro. Then they made me a judge. Yeah. If you can't beat them, judge them. So what's neat about that is, I mean, there's a how-to site because some of the times when we see the large language models and what they, what's like, make me some code that runs on a microcontroller, it's all our code. We're totally fine with that. Because it's like Adafruit, it has the variable names that say Adafruit all over the place. You could probably just cut and paste the code. It's probably faster than going through a Shinshan GPT like thing. But it's interesting to see where it's getting this information from. So of course, like right away, like, I'm like, let me try Adafruit. Let me try. It's part of it. Let me try some other things. So there's a little prompt that you can put in the website. Hackaday was like 300. And that's interesting to me. I started to site a long time ago. It's a lot of content on it. And it goes back like it goes back over 15 years. And so there's a lot of technical content there. And that's why some of the times I'm like, well, this is actually pretty good. How did it do that? How did it predict the next word? Because it's essentially what does peanut butter and jelly. So it knows the jelly. And that's just a very, very basic example. And I think Google CEO did the same example. And he's like, does that work? But check out what's in there. Because, you know, obviously they're scraping learn. And obviously they're finding a lot of resources. We're okay with that. I have some opinions about the best way to do it and how they could source that and say where they're getting it from. But it's kind of interesting. That's where we're at now. This will all be solved in the lawsuits later. But for now, check out some of the, see if you can find, if you put something on Instructables, use, ask some of these large language models. It was really popular. It was doggy wheelchairs. How to make your own. Yeah, that was a very popular. Yeah. And there's some projects that are like a little on the line of legality. And like, maybe, maybe it'll say, well, I can't show you how to do that. I thought that was interesting. So that was the news for that. Sorry for it. So the time-off case, that was, some of that I thought was a time-off. This week's 3D Hangouts. Yeah. I totally had a brain bled. We're gonna, we're gonna play the video. Yeah. Okay. Let's do some factory footage. And that's the factory footage. One thing, George just mentioned this, and I have to, because we just had a very similar conversation. George just says, the AIS stuff reminded me of the music samplings of the 90s. So Two Life Crew got an incredible amount of trouble, all sorts of things. But a lot of it was music sampling at the time. And I was just talking to the lady about Two Life Crew. I don't know if you ever heard of them before, but they weren't like, they're just like, they're just like breaking every rule possible. And they were in court all the time. But it does remind me that when music sampling first hit the scene, it's like, is this okay? All of music is music sampling. So we'll figure out what happens next. Anyway, I knew it was gonna come up somehow. Good. Good work there. All right, anyways. The Two Life Crew was mentioned in Act 1. Their music must be played by Act 3. That's right. Let's do 3D printing and we'll see you on the other side of those videos. You can build a time-lapse rig with the new camera module from Raspberry Pi. We were able to capture the stunning time-lapse with dynamic exposure thanks to the new Pi Camera's HDR mode. 3D print our snap-fit case to house a Raspberry Pi 4, Pi Ramoni's 4-inch hyper-pixel display, and the new camera module V3. The new module features autofocus, a 12 megapixel sensor, and an HDR mode offering excellent image quality. High dynamic range means you can capture perfect exposures in your time-lapse videos. Whether you're looking to capture blooming plants or fluffy clouds, you don't have to worry about blown out or underexposed images. Get the parts and accessories to build this project. Links are in the description. Download the free files and 3D print the parts to build the case in your favorite filaments. Start by installing the camera's ribbon cable through the slit in the front cover. Short standoffs secure the camera to the front while the Pi is secured to the back with machine screws. The hyper-pixel display fits onto the Pi's header and the enclosure goes over the whole assembly and snap fits onto the front cover. This mounting bracket holds a quarter 20 tripod screw and gets secured to the side of the case with additional screws. A separate cover snap fits over the camera module's PCB to keep it protected. This tilt ball head makes a nice addition to a mini tripod and allows you to position the camera in different angles. We hope this inspires you to check out the new camera module from Raspberry Pi for making your own time-lapse rig. They design single board computers and they have a new one. It's like if people remember the Beagle Board, original on the Beagle Bone. They have a new one called the Beagle Play. So this is the Beagle Play. It is chop-full. This has like everything in it. It is a ultimate, all possible connections available. New York's hottest club is Beagle Board. It's there. It's all there. This is the back of the board. So this is a base. It features a ton of chips from TI. The main core is, I'm trying to remember, it's 8D Sitarra AM6254. It's a quad core A53 chipset. It's also got a cortex M4 in it and it's got like tons of add-ons. So you might be familiar from this board again. The previously most popular board was the Beagle Bone, which had actually a couple spin-offs. There was the Beagle Bone Green and the Beagle Bone AI. But the Beagle Bone, it was a predecessor to the Raspberry Pi. The Raspberry Pi came afterwards and this board was really neat because with single board computer, it had Ethernet. It had DC power in USB and a lot of GPIL. And it was very inexpensive. It was about 60 bucks, which is, at the time, was pretty amazing considering that PC one of four boards easily started adding up and could be a couple hundred bucks a piece. All here because of the chumby. We really are all here because of the chumby and the Beagle. If you like the Raspberry Pi, single board computing, go Bunny. Thanks for bringing this into the world. For makers. For makers, yes. It was like, we all saw it and were like, oh, wow. This is cool. And I remember Beagle Bone came out and was like, this is awesome. Very cool. And we heard it. And the thing is, is that, and there was also, you know, the Beagle Board exam. This is actually the original one. And this was cool. But I think, I think we remember like why this was not as popular. I think it was just really hard to add more hardware connected. You see, there's like two audio, but I think it was tougher to connect to the GPIO. I think the GPIO wasn't easily exposed or is it going to point to or a two millimeter pitch header or something. But this was like the original. And then, you know, this is that's available. And then the Beagle Bone is still available as well. And this has, we have support for it and a lot of people have support for it. So the Beagle Play is just like when you're going to, when you're on a website and you're ordering something like a pizza and you're just like, you know what, I'm skipping everything on it. You want broccoli, you want ham, you want pineapple. Yeah. Okay. I want rockstar, meatball. I want pineapple. It's okay. So there's a lot. Actually, you know, let's go to the next image first. And then we'll go back because this one is actually a little easier to talk about. Okay, so the main core there is the AM66254. Like I mentioned, it's an A53 cortex. Quad core, I think it runs at 1.3 gigahertz. There's also a cortex M4 sub processor in there. It comes with, there's on chip SRAM, but then there's an additional 2 gigabyte of DDR4 memory and 16 gigabyte of EMMC. So that's where the file system and operating system live. There's a real-time clock, the BQ32002. On the other side, you'll see the battery holder for it, which I think is really useful. It's like a lot of times people have an add-on to their Raspberry Pi where they add a real-time clock, but this is like all built in and ready to go, even with that coin cell battery backup so you can pull power and it will know the time even if the internet doesn't connect. There's the TPS652191 PMIC. That's just the power management because there's a lot of rails on this board. The wireless and connectivity is really interesting. So they, I don't want to say they went overboard, but they kind of went overboard in a good way. So they've got Gigabit Ethernet with the RTL 8211F and they have a separate single-pair Ethernet. That's the RJ11 on the other side and that's with the DP83 chipset. Those aren't like the controllers. I think those were only like the fives. I think the Ethernet support is, of course, built into the SOC itself. For wireless, they've got WL8707. That's a dual band, so 2.4 gigahertz and 5 gigahertz Wi-Fi, two separate antennas. The antennas come with the board and they have a separate CC1352P7 and that provides VLE and sub gigahertz. Sub gigahertz in this case is ZigBee or Thread and other 2.4 gigahertz. Sorry, yeah, 2.4 gigahertz. I think 900 megahertz. It doesn't have Lora support, by the way, because I looked and it was like, okay, it doesn't do Lora, but it does do like basic packet radio. So there's also two antenna ports for that as well. So let's go back one. So it's the main chips. So there's like 15... There's all the fixings. There's all the fixings. So starting at the top left, you'll go clockwise. So there's the real-time clock battery. So I showed you the real-time clock on the other side. You'll need a CR1220. Just pop it in there to get battery back up. There's user LEDs. They blink when you power it on and all that good stuff. There's a JTAG connector and this uses that like quick JTAG link or something. I can't remember the name of it, but it's like, it has little press fits and you plug it in. So you want a JTAG connect to the AM6254. You can do that. The microbus, so this is for microelectronica and then you have like a thousand different breakout boards for like every single SPI, iSquad C or UR or ADC board and you can just plug them right in. So there's a socket ready to go and there's like the little outlines showing the three different sizes. There's OLEDi, which I was trying to research a little bit and I didn't get very far, but I believe it's like LVDS compatible. There's CSI2. So that connector there is the camera connector and it's pin compatible with the Pi Zero camera connector. So if you want to use it with Raspberry Pi cameras, just get the Pi Zero to camera connector. Then there's Grove expansion and that gives you, you know, UR or iSquad C or there is an analog output groves. I don't think there's an ADC on here and I couldn't find there's an ADC on the chip itself. So I think it might not support the analog input groves. It only does like your iSquad C and GPIO. There's a quick expansion. So this will work with all of our STEMI QT boards as well. So that's a ready to go iSquad C and they have a tutorial I'm actually using. This is like the one thing they had a really good tutorial on. There's a user button that you can use. There's a separate microSD storage. That's not the main operating system storage. Although you can boot from microSD card if you want to configure it. Why not? You could, but you could use the onboard storage EMMC which is going to be nice and fast and then the microSD for data logging or whatever and that's you can mount and unmount it. There's a reset button. Again, there's that JTEC connector, oh sorry, there's a separate JTEC connector for the TC-1352. That's the wireless connectivity. A power button. You hold that down to turn on the connectivity LEDs for like all the different connections and then the single pair ethernet which I found interesting because I've never really seen a single board computer that had single pair ethernet and on one hand it's pretty cool. Could be that a lot of robotics and automation are moving towards single pair ethernet. We covered it in a previous INFPI. If so then you can maybe get power and data over one cable and that could be really good for robotics and stuff because this is a nice small board with four mounting holes. Yeah, this could be robotics board, home automation board. It could be both. Yeah, it's also got gigabit ethernet and HDMI out 1080p, HDMI from the built-in and the Beaglebot had a separate chip that did it. This is actually like natively on the AM 6254 core. USB-A 2.0 host. There's only one USB port so if you're used to Raspberry Pi you'll look at that for four ports. It's because they had a hub built-in. You can just attach an external hub if you need. There's your debug header, so ground RX and TX and USB-C. I'll be honest, I actually didn't use the USB connectivity but probably if you plug in the computer it shows up as a gadget device. It's also used for power so I just plugged into my USB-C power plug and it worked fine. Okay, so that was a lot. Let's get into some of the parts. The main core is the AM 625 series. It comes in one, two, four core. This is the four core version. Max frequency, 1.4 gigahertz, 64 bits has Linux support. You can check out, there is a bunch of hardware support here. It's got CAN, GPIO, SPI, iSquared-C, Wolverine coder, et cetera, et cetera. Tons of great boxes. There is a tutorial on using iSquared-C for the Stemma and Quick. I believe that it might only have iSquared-C support via Grove but a lot of things are iSquared-C so you'll be good for that and then what we're going to do is, I just got this, we're going to get Blinko working on it so you can use all of our Circuit Python library drivers. Just great timing because for the folks who are like, well, I need a single core computer and whatever. I'm just going to get something now instantly because I can't wait for Raspberry Pi. To be honest, it's under a hundred bucks. It is actually cheaper to get this than to get a Raspberry Pi, add the EMMC, add the real-time plug. Yeah, you can't get all of these single pairs easily. If you use Blinko, which we're going to have, if you've done Python things, then it works everywhere. That's the reason we did it because we're like, well, maybe one day people are going to be using all these single core computers and we don't want to rewrite the drivers every single time. A lot of stuff and what's nice is, the only thing is there's no GPIO. The GPIO, if there are any, are on the micro bus. A lot of times, let's see the trade-off, you can't plug in existing hands or bonnets, but it has everything built in already. I think for a lot of situations where people are using Raspberry Pi, but they don't need GPIO, they just want you to connect accessory boards, this is a no solder solution. I actually like that they want a different direction. They're like, we're not going to try to make a Raspberry Pi. It's kind of a waste of time. I feel like there's this, like, what's the Raspberry Pi killer? It's, you know, banana pie. I want to try, like, this is something different. Yes. And I like that. Like that they want a different direction. That's right. Okay, that's this week's IonMPI. Check it out. It's double now. It's 262 in stock. Yeah. Okay, later, before we go off to new product land, the code is RP Think, Inc. It'll all make sense in a few moments. Let's kick it off with some new products. All right. All right. Well, last week, we didn't have these in stock, I think. Yeah, in stock, Coaster. Coaster is what they did for logo. Very rare, because we don't put anything, we don't really put logo anything other than PCBs. So this is our way around that. Yes. And they come with Mumper, which we're not shown in this video, but they have a little buffer. Super cheap. Comfortable. Next up, we've got a panel mount for the Raspberry Pi 3 cameras. These have a slightly bigger, like, camera body. And so I think we already carried the camera V2 version of these. I think these are from Pi Hut. But they're inexpensive, they're easy, and they basically give you like a big plate in order to mount your Raspberry Pi 3 camera. This is obviously not the big lens cameras. This is like the noir or plain autofocus cameras. Next up, we've got an update to the ADI wing. This was done in a partnership with DigiKey. We had to do a couple of visions for stuff. So we're like, let's go in and revise it. It's the original version. You can see here did not have a STEMI QT port, but now it does. So you can have all the parts from the space in the same location, but now you've got STEMI QT connection. So you can add more sensors. Or you probably could connect directly to this. I mean, you wouldn't get access to the interrupt pins and stuff. We've also got an update for the Metro ESP32-S2 Express. First off, we put a TVUSB logo on there because we wanted to celebrate the work that TAC has done with TVUSB. And second... What's that cool logo, by the way? Cool logo. See the eye is a little ESB drives. Oh, that's fine. Is it for cool? And thanks to Bruce for designing it. The boot button moved. The boot button originally... Oh, can you go like... Yeah. Yeah, because I'll show you the difference. So the boot button, you was in the middle and now it's in the top right on the edge. So it's easy to get to. So you can actually load into the boot loader without pulling a shield off. It's got the STEMI QT still. It's got the ESP32-S2, four megabytes of flash, two megabytes of RAM. It's got the JTAG connection. Even though, to be honest, all people use JTAG. But if you wanted to, it's SWD is there. USB-C with fuse, DC power with on-off switch, regulator and LiPo battery and charger. Because we figured the ESP32-S2 and Wi-Fi would probably want to take it, make it portable, even though it's not super ultra low power. We also changed the battery monitor. It used to be a resistor divider. It now is a Max 17 048. So it works a lot better because the ADC on the ESP32 is not linear and it uses a lot less power. All right, more revisions. Another revision. This is the original, sorry, go back. So this is the solar DC charger that is our original. We have two of these. And this one is the first one we designed. And it features the MCP73871. The original version had a mini USB connector. We were going to do a revision on this. We had to change the DC jack anyways. And so, hey, why not do the sub-screen over? And now is a USB type-C connector instead of a mini-B connector. All right, number 390. This is deep cut. It says early. Yeah, this is very early. But I will say we have what I consider a better solar charger. But this one is still... There is some benefits to this over the other one. And they're both very good. So for people who need the old version, I'm going to keep it around. Okay. All right. And then these we were just getting to putting these in the store last week. And we wanted to spend more time on it since it was a pretty long show. So we want to dedicate a segment to this. These are the new floppy disk costumes for SD cards. Yes. And this is my Charlotte. And these are so cute. So this is you take a standard SD card and you put these stickers on it. And then they look like little floppy disks. Yeah. All day long. We're all like, hey, retro, fun, everything. But we're not able to make our SD cards look like the way they should. So now... Now they do. Now you can end. This is okay for the SD card. Now you can write on them. And you can put these out. And then you can tell the youngins this is how we used to save things. Yes. So you get a pack. You get a pack of eight and two of each color. Blue, pink, yellow, and... And start an independent maker for all these ideas and cool stuff that's coming on. Very cute. All right. This star of the show tonight besides you, Lady Aida, our team, our customers, our community, and everybody who makes things go is the Thinkink. Yay. The Thinkink feather, which was originally the Thinkink Trinkie, but people didn't know that. How would they know that? Because I didn't tell anybody. They decided to turn this into one of our feather bones boards. So this is an RP2040 feather. And on the end there, it's got a standard 24 pin EPD connector. And I'll talk about that. It's got USB-C. It's got battery. It's got RP2040. We said food button, battery charging, eight megabytes of flash, 264K of RAM, stem and QT port, lovely silk screen with penguin. And then all the GPIO you can shake a stick at. And the way the bones board work is it has all the standard pinout for GPIO on the feather. And then we usually have about five, six pins left over. And so what I've turned that into is I've connected them. You see on the right there, there is a power supply and manager for a 24 pin EPD. So it's really overhead. And I'll show the EPDs. So the displays almost all have the same connector on them. It's a thankfully kind of a standard. They're these 24 pin connectors. And this is a 2.13 inch. And this is a 2.9 inch. And this is a 5.65 inch seven color version, which I think is neat. It takes a while. We can see it's like it's got gray and orange and yellow. And they all have the same connector. And so you can easily pop out and replace a different e-paper display. And then you'll have to change the code for it. But all the boost circuitry that you need, you need all these components to make it run are pre-connected for you. And the RP2040 is a really great chip to run e-ink displays because they need a lot of RAM. And they need a lot of RAM because you have to draw the entire display at once. That's why we call it thinking. Thinking. Or than just an e-ink display that goes into this. It's a bunch. It's a thinking. But you still get all of the feather pins besides. And so you can connect your e-ink display. We have also extension cables for this connector. And then you can plug feather wings on top if you'd like. So if you want to connect canvas, you can pop on a canvas feather. If you want to add on. So I'm just like, all the e-ink, all the other feathers that we've got. If you want to add joystick or TFT or Ethernet or Wi-Fi, also you can do that by just plugging in a feather. But for a lot of purposes, if you just need to have a board that runs any standard e-ink display, and you don't want to do any soldering, this is plug and play when you go. All right. It is this week's new products. Okay. Don't forget the code is rpcingank. We're going to do questions. You can pop them in the chat. While we do a very long top secret segment. So buckle up. Don't tell anybody because this is a top secret, right? But we'll see you on the other side. We're going to play some videos and then we're going to show some of the renderings from some of the new things that are coming out. So here we go. Early data, where's this? This is an IntelliQey's assistive device, which has a matrix of touches, which is behind it. And then these swappable overlays, and each overlays a little bit different. You see this one has like mouse and keyboard and pretty keyboard. And this has like a bigger kind of alphanumeric keyboard. And it uses a photo cell to determine which overlay you have installed. And this is really useful device, but unfortunately it's no longer supported. And the driver downloads firmware over USB from the computer, like a Windows computer. And so if you're not running Windows 10, but other devices like Chromebooks or tablets with mobile can't use this because they don't have that driver firmware to download into this device. But what we can do is use one of our USB host feathers. And what this does is HID translation. So this chip enumerates the IntelliQey's through the USB connection, downloads the firmware, and then asks it what overlay it's got, and tacked an amazing job reversing during the original driver. And then to connect it to something like an iPad, you would connect using what's called a camera kit. And here I've got like the notes app up. And then you just give it a second because it needs to download that firmware. It'll beep when it's ready. And then you can type on this and it shows up just like keyboard input. So hello. I, space, oops, I, space, am, space. It's tough to type on a telly. All right. Good enough. Good work. Working. How late are you to business? This is me testing out the Feather RP2040 with e-paper support. This is the Think Ink board. So this Feather RP2040, it's great. It's got 264K of RAM, which you need because you have to buffer ink displays. And it's got a standard 24 pin connector. Pretty much every display for ink that's not like a reader display, like the standard static ones, color, you know, monochrome, tricolor, etc. They all have the same pinout on this 24 pin connector, which makes this Feather really great for making all sorts of ink projects. So let me line this up and run the test. We're using a Pico to program the RP2040 through mass storage. This works really fast. And then when it passes, it lets you know by beeping and also changing the display. So coming soon to the Adafruit shop. Really? What is this? Hey, this is an Adafruit RP2040 Feather with DVI. And it's driving this monitor to make some flowing toasters. Philby updated our guide on Pico DVI to add a couple of fun screensavers. So that's one. And then let's load up. Got a couple others here. We've got Aquarium. So I basically said, hey, here's my two favorite after dark screensavers. Hold on, it's loading up. And then give it a second. It's like thinking, thinking. And then Aquarium. I love this because it was just like fish. And it was a pretty chill and peaceful. There's also a very cool Max headroom demo starring JP. TV host. But you can customize it with your own graphics as well. So check out the RP2040 DVI Feather. You can drive monitors really easily in Arduino and the Adafruit shop. All right, Lady, what is this? This is me testing out Scott's latest Circuit Python build with DVI output support. Look, this is out of monitor connected. And you see my monitor connected to the DVI output. And it's running Circuit Python. So I can run codes. For example, I've got this cool port of Turtle, which is, you know, like logo for Circuit Python. It's cool. And then there's also, let me run the Sirpinski triangle demo. That one worked really well too. So copy and paste. So you can now do graphics really easily. So if you like Circuit Python using Display IO, but to an HDMI monitor. It's pretty cool. I love triangles. Okay, and we got some samples of things in and some coming soon. Look at everything right now. It's okay. This is the TMAG. So I was just digging through like out of pile of chips from like a couple of years that I was like, oh, finally can get it. So this is a 3D magnetometer from TI. And then this is kind of cool. This was actually Anne's idea. This is a, and actually a prototype built of it. So I can show it. Yeah. So we're getting really close. Just we have DVI. So that means we have video. We've got keyboard stuff. We've got mouse stuff. We've got joysticks. So this is a PC joystick to STEMI QT adapter. So this is a AT tiny and it's done doing C-Sauce. We can get the analog inputs and button inputs and convert them over. I suppose you for reading. So this is a couple. I'm going to say it was great when we first started getting Wi-Fi on microcontrollers. Yeah. Super cool. Amazing. Now we finally get like video out. Yeah. Because like video was like, that was like for a microcontroller. Normally you'd like to use a computer. Yeah, it's been around for a while. I was talking about like really low cost, super fast, instant video out on microcontrollers. And then being able to plug in something like a PC controller, like game controller, like phone for Raspberry Pi-esque, but shrunk down and then super low cost. Okay, what else? Okay, this is a redesign of our feathers. This is the one side, that's the other side of the feather wing TFT plus joystick. So this board set got like the worst. Everything had to be redesigned. You know, that'll be funny after we say like the chip shortage is over over. Like which board got... This board got at the worst. Is it the same? Sorry, the clue got at the worst. The clue like almost every part is. Is it still the clue if we replace everything? Is it, you know, that phrase like if you replace the plank on the boat, is it the same boat? Yeah. Is it still the clue now? It's well, it's not in stock. So now. And then this is a quick board. I just, I just put together, it's a 18-bit ABC, the MCP 3421. I thought that could be handy. Maybe you need an 18-bit ABC. It's slow, but maybe you don't care. Maybe you're like, I just need something. And then this is kind of neat. Actually have this one as a finished prototype as well. So just give me a second. I'm just digging through. There's a bunch of stuff that I can see here that you all can't see here. It's really a lot of cool stuff here. Piles of stuff. Because it's like we wanted to do our top secret, but we're going to see. So this is, yeah, this is the FUSB. So let's go to the overhead. So this is a chip that is I squared C and can do power delivery. Communication with USB type C. So the idea is that you can connect this to a microcontroller and you plug in USB type C here. And it will, it'll default give you five volts and you can request like up to 20 volts. And then you can get that higher V bus out here and you still get the data plus data minus line. So it's kind of like a USB-C hacking board. It could be interesting because definitely there's project sports. Like it would be so cool if you plugged it on my controller board into a power delivery and you could get like 12 volts. And you could one your motor, you don't need two power supplies. You don't need USB and something else that has all in one. So this is going to be kind of neat. So this is the FUSB 302. Do you have any other things you want to show before we get out of top secret? No, because we should do some questions. Yeah, we're going to get some questions. Yeah. Okay, that is this week's top secret. Okay, we're going to do some questions. Yes. It was a ship of thesis, but. Ship of thesis. But you can call it the chip of thesis. The chip of thesis. Good. Top five came in this week. That's good. Okay, let's do some questions. And then we'll see what else we got. Yeah. On IMPI, what's the micro bus thing on the board? What's that? That's micro ease, like plug and play. It's kind of feather wing. It's like they have multiple definitely hundreds and hundreds of boards. They all use the same pinout and they don't have like Arduino drivers or Python drivers. It's written in their own like CSDK. But if you just want hardware that's broken out into these plug and play boards, I think they're fully assembled too. Okay, do the 24 pin E paper pinouts very much or are they sort of standard on signal types of power? All of them that have the 24 pins have always had the same pinout and power. Some of them need more power because they're bigger displays, but for the most part they're all pin compatible as well. I think there was one display that Scott found that had the, it was upside down. But in general, if it's a 24 pin connector, it's the same 24 pin connector. How do you flash around our 52 840 boards? Well, we use the SWD pins and there's pads on the bottom and then our Pogo jig next to it. And some of our boards have a SWD connector. Okay. Any plans to make module for the USB PD that breaks it out? Five volts and 3.3 volts. Those are what I use most for module pretty great. Yeah. I think there's something there, right? It's this one gives you 3.3 volts, but it's an LDO just so you can kind of get your microcontroller up and booted. Like you need something to get started and then you can have separate power supply. But I think for most people what they would want is you get that high voltage and that's what drives your motor. And you don't necessarily need that much current at 3 volts. Although you can also request 5 volts, I think up to 5 amps. I think it's possible from power delivery, but you need to have a really good cable. All right. And then last question. Ready? How do you go about troubleshooting complex circuit board that you have no schematics? Sure. What would you do? I would check the power supply. Because that's kind of like there's a couple of things that are the most common. I'd look for capacitors that are blown, time-slump caps, short out, electrolytic caps, fail open, busted traces. I mean you can't. Yeah, new continuity. You can check the power supply, fuses. Usually, I mean like salt states, capacitors break and the power supply dies, but not a lot of other things fail on a solid state. Okay. Okay. Okay. Is it? So, we're going to say thank you so much. Don't forget the code is rpthinking. Which are on sale. They're in stock. They're in stock right now this second. You can get these. You can. They are purchasable. You can get these. And then you don't get the display, but we'll have the displays in the store. Yeah. We're trying to make it super easy. So, if you see anything that says thinking, it means that we can like work with our displays. The pinout is even on the back. The pinout's on the back. How convenient. Yeah. So, that's our show. A special thanks to Jesse May behind the scenes and Nate Fritzlack. Doing stuff. Thanks everyone for keeping this going and coming up with cool projects and making this fun to do that support. There's a lot of cool stuff you can do electronics right now. We have so much stuff coming out. I know. We have so much stuff coming out. And what's cool is a lot of the stuff that we're working on is stuff that when someone gets it, they're going to be doing the fun. Well, the more the other part of it, which is making cool projects with it, like the Feather DVI thing. That's going to make you're going to be able to do cool amazing art. We don't even know what people are going to do with this. That's why some of these are so exciting. I remember when we did Cricket with robotics, it was like people are going to come up with amazing robotics projects we didn't even think of. And that's, I think as a creator of things for people to make things, that's when I think it really hits the feels when you see someone do something that you didn't expect. So thank you everyone for doing that and also sharing it. So we'll see everybody on show until next week. We'll see everybody on Ask an Engineer next week. That is our show. This has been Adaford Production. Here is your moment of Xenar. Bye everybody. Thanks for tuning in.
