 Ford Life in New York is Ask an Engineer. Ask a train engineer, no ask an electrical engineer, it's me Lady Aida, I'm the engineer with me Mr. Lady Aida on camera control. We just took a train here, a train from the past into the future. We'll be talking about that in the show. We've got an exciting show for you tonight, we're broadcasting live as always from the headquarters. This is where we do all of our kidding, testing, shipping, manufacturing, coding, videoing and shipping, whatever I just said, multiply that. We do a bunch of things. All the time, that's why we're a little out of it. Everyone's home right now because it's just me and Mr. Lady Aida. We've got a jam-packed show for you for the next hour. You're going to hear about all the latest news, updates, new products, videos, tutorials, LED cats and more. Mr. Lady Aida, tell them what's on tonight's show. All right, on tonight's show, the code is Uncased, 10% off in the Aida Fruit Store all the way up to 11.59 PM Eastern time or when I remember to turn the code off. Get to 10% off in the store and you'll also get free stuff as you shop on the site. We do a live series of shows, including Show and Tell. We'll talk about that, who's on the show and tell and what they shared and more. Time Travel Around, World Makers, Hackers, Artists, Engineers and more. Retro Tech, we'll be talking about that train ride we took from the mailbag. We'll read your letters that you send us. A job from the Aida Fruit Jobs Board, Jobs.AidaFruit.com. Post your skills to pay the bills or if you're a company hire cool amazing people in the community, do the projects you want to get done and more. We have some factory footage. We call it Advanced Manufacturing, made here in New York City. We got a 3D printing speed-up video. We've got IonMPI. This week it's from Worth Electronic and we've got new products, lots of stuff this week, some top secret. We answer your questions. We do that on Discord. Remember, questions. AidaFruit.it slash Discord or Discord.gg slash AidaFruit. That's where we do the questions. Join all 34,000 of us there and the party still goes on even after the show's over because people hang out and chat and share and do all that stuff and more. All that and more on, you guessed it, ask an engineer. Okay, well let's pay some bills real quick. Don't forget, the code is uncased and it all makes sense soon. And when you purchase things... Or Unca said. Yeah, Unca said. Yeah, could be that too. So, Lady Aida, when they buy stuff though, they get free stuff. That's right. We have freebies and we change them out. For now, if you order from the AidaFruit store, AidaFruit.com, you get $99 or more a free promo proto. Hashtags breadboard. We love to give these away as freebies because they're so handy. Just keep it in your drawer and believe me, you'll use it soon enough. $149 or more, you get a free KB2040. It's an RP2040 board. That's pro micro pinout compatible. It has a stomach UT port. It's got 8 megabytes of flash, USB-C, cast-related pads. And it's designed for keyboards, but you know what? You can use it for anything and it comes in a cool pink color. And $199 or more you get for UPS ground shipping in the continental United States. Okay, cool. And reminder, there is more things in addition to Raspberry Pi now because the park shortage continues on. Make sure you make an account on AidaFruit.com. You verify your email and you do two-factor authentication. That's good security for you. You should do that on every website. And if the website doesn't offer that, you should drop them an email. And if they say, well, we're just an electronic site. They say, well, I know an electronic site, AidaFruit, they're doing it. But it also helps us make sure that we can fairly get Raspberry Pis specifically right now. But there's also TCs that are in that limit to the most people. So I'm going to skip around this week and we're going to do Mailbag because this Mailbag is yet another one that has something to do with this shortage. Before I do the Mailbag, though, for the Raspberry Pi orders in particular, there is a pretty big, I'd say, group of people, but they have bots, but there's people, someone made the bots. Half bots, half questions. Yeah, and it's working like we're able to not have people buy all the Raspberry Pis, make tons of fake accounts and get them and then put them on Aida and send them for $300. And they're starting to move on. That's good. They still try, but we've done a really good job. And the folks who do get them, they let people know on Twitter, like, oh, I got one. I've been waiting for like two months and I was able to get one. So that's really helpful. And then there's a couple of folks that are really cranky and crummy because they're like, well, I need 10 Raspberry Pis for my project. It's like, well, right now might not be the best time for a project that needs 10 Raspberry Pis. And they're like, well, I've already got one. I'm going to get the other nine in there. They're not so nice to our team when they email. So anyways. Don't do that. Yeah, so any who. Let's do Mailbag because this Mailbag happens to be a Mailbag about the Raspberry Pi stuff. So I remember to put the song in this week too. Yeah. It's right over here. Yeah, we changed screens. That's OK. Giant screen. It's like. It's so big. It's like there's a lot going on here. It's all screen. There's. We get letters. We get tweets and we get emails. You're. OK, this week's Mailbag. This is from William. It's a long since I want to get to it anyway. Hey, nothing that requires a response. Just wanted to give you folks positive feedback. I've been reading about the Raspberry Pi shortage and saw that you folks are going out of your way to ensure scalpers don't pick up multiple pies. And I just want to take a minute to say thank you and time where profits always seem to come before customers. It's become a rarity to see something like this in action. I have several friends who have worked for Orange Coffee Roasters. That's a coffee place in New York. Several who went to work at Adafruit and I've heard nothing but good things about your company and how it treats its workers. And it's clear that you folks treat your customers the same way. Anyways, having worked in customer service for a while, I know how rare it's actually to hear something get from a customer. Yeah. So I wanted to take a minute and share what an awesome company are in hopes that it makes someone's day a little better. It did. Little decisions like this make all the difference in the world and I'm happy to encounter a company that actually cares. Yeah. Thank you, William, because we spend a lot of time on all this stuff and it's been- We get letters. Yeah. We get faxes. They complain we don't sell them 30 raspberry pies. Yeah. Yeah, actually the Better Business Bureau, they left a voicemail message for me. So some person doesn't like that they got caught, you know, selling raspberry pies on eBay and we're not allowing them to buy stuff in the store. And they think opening up a Better Business Bureau complaint will solve that, which it won't. It's not discrimination, folks. I know you think it is, but it's not. Yeah. They were selling raspberry pies on eBay for like 300 bucks and we told them don't do that. They did it once, but you can't do it twice. And so we're not allowing them to buy raspberry pies. So anyways, so I like this letter. This makes up for that one. So thank you so much, William. Thank you, William. So let's talk about our live series shows. We just did one. Yeah, we just did one. We do a bunch of live shows. So we just finished Show & Tell. Show & Tell was fun this week. Cool art. Kevin from DigiKey showed this like immersive, almost VR looking thing and it's the innovation hub from DigiKey. I really like this and I don't know how long they've been working on it, but I think their timing is really good because people are starting to want different experiences online because the web is kind of trash. And I mean that maybe in a good way. Like, you know, most of the web is really hard to find stuff now. And that just means there's more opportunities for all of us to have special experiences on our websites. So, you know, if you type something in Google, like it's really hard to find the results. There's just like a lot of stuff going on. That's not the results you're looking for. So, you know, the idea is you would go to the DigiKey Innovation Hub on this site experience they have and you'd be actually, you'd be able to spend focused time and explore these things. So, I really like this idea. I hope I get to try it out soon. And I think this is the first time it's been displayed to the public. And then Scott came on and showed some neat stuff with CircuitPython. That's right. And then Rachel came on and Rachel had this really neat LED backing. It's our matrix panel with Legos in front of it. And my prediction, and I said this on there, Legos totally going to do an LED panel that you put Legos on top of it and you like do designs and have stuff behind it. Like, they watch our show and they look at our site. And I know for sure Legos does. So, I think they get really good ideas from, you know, the maker community as they should, because that's why we're here, we all want to share ideas. And I think that might be like a product one day where you would have a panel behind the Legos and be able to make it really cool immersive stuff with Legos in front of it. And then John came by and showed this cool garage door detector. That was neat. So anyways, you can check that out on YouTube or any social media place where we post and host videos. On Sundays, we do Desk of Lady Aida. That's right. And we have two parts. The first one was? Well, we talked a little bit about how we went on this train, which we'll show a lot more photos and videos of. And then it was a sample Sunday, so I went through a whole bunch of samples that I got. I've been trying to clear out my massive pile of samples. We got some Elkai solder kits. We've got these cool hex wrenches. We've got laptop battery adapter. We got some clear RGB encoders. And everyone agreed that these were good samples and so I'm going to order them. Okay. And then we do the great search. And this is where Lady Aida uses her powers of engineering and smarts and stretching the digikey.com site to find the parts that she needs or you need or someone in the community says, hey, I need help finding this. What was the part this week? Okay. So this week, you know, we had just stopped this iSquared-C capable sonar sensor. And I like it, but it doesn't work so happily on multiple iSquared-C device chains. And so I thought like, well, I wonder if I can make my own ultrasonic sensor. And so I Googled around a little bit. I found a couple tutorials and people had like taken apart and done reverse engineering of sonar. I didn't see a lot of people who'd made their own sonars. Usually people tend to use off-the-shelf modules. But I determined that it should be possible to do with a single transceiver. And so I went to digikey and located a CUI 40 kilohertz ultrasonic transceiver module that I ordered and I just got them today. And they're cute and adorable. And I'm going to try them out as a distance sensor see if it works. Okay. And then JP was off this week for JP's product pick of the week. So we'll be resuming that next week. Same thing goes for JP's workshop this week. So that'll be coming up next week. Also, Fridays, we do deep dive, 2 p.m. Pacific time, 5 p.m. Eastern with Tim. And this is where you can get a good overview of all the things that go into the deep parts of Circuit Python. So if you like the movie Abyss and you want to breathe water, that special suit that they had to go. Maybe he's in Sphere also underwater. Sphere was underwater, but I feel like in Abyss, he had to stop this bomb from going off because the guy, anyways, it's a long story. It's a long story. But it was deep. He was so deep he had to have the special suit. So that's what Tim's like. Tim's like the guy that's going to save the air. Oh, he's got like the big like heart. Yeah, and he's breathing in oxygenated water. Okay. That's what the show's like. Yeah, but code. But Circuit Python. Okay, time travel. Time travel this week. I'll do the weekly reminder. We're still hopefully, hopefully, hopefully doing Eight of Box Spring Edition. If you didn't get your Eight of Box Winter Edition, it's because there's part shortage. So we're still trying to get these out. Don't worry. We don't charge the cards until we ship it. So you don't have to worry about that. It's part shortage. Yeah. All right. So let's do some retro. Yeah, let's do some retro tech. So this week's retro tech is really, really retro. But it is electronic. It is. So the Transit Museum in New York does historic rides, nostalgia rides, but they haven't been able to do it for a couple of years because of COVID. So basically there is a really old train, old train station inside of New York's subway system. And they will let you book tickets to ride a, you know, a hundred year old subway train on the regular subway route. And so we went to it. This was Explorer South Ferry Station. And a couple little facts about this. 1905, Old South Ferry Station contains a terracotta relief artwork designed by regional subway architects. It was built as a loop station so the trains could turn around and head back. It was built for five cars. It was decommissioned in 2009 when the New South Ferry Station opened. And then it had to be reopened when Sandy hit because the other station got closed. And then the low V is the low voltage train and I'll get into that in a second. So you go in into this other entrance and they have like the old style subway. It's really beautiful. It's really neat. It is like going into a time machine and, you know, has the old fixed years with what track is where. Here's a lady at it in front of the car. This is a car that we got in 5290. Here's the sign. You know, the signs aren't lit up. They would just put a different piece of metal in there. Everything's made out of steel. Yeah, here's the strap. And it's been going on for over 115 years. That's how old the train is. And then here's some of the things. Hi, I'm a lovo lovo train type. I was born in 1924 and operated in passenger service until 1969. And then this is another one. And Lady Aida could probably explain this. This is the car that we were in. So they use low voltage. And these were safer for crews. And they would operate at 32 volts compared to the 600 volts now. Yeah. So I imagine that the older trains were very simple. Obviously, there's no electronics. There was maybe a couple of simple relays and switches that were manually controlled. And they didn't have a transformer or a separated power supply. So, you know, if you had a relay switch on the control line and a wire got loose, you could get 600 volts into the control interface and ZAPI, which would be really unpleasant. 32 volts on the other hand, you won't even feel it. So 32 volts, 24 volts is what most cars and trains run at for the interfacing. And then there's a separate high voltage section. So good idea that they separated them. Considering that the entire train isn't made out of steel, you definitely do not want it to accidentally get high voltage-ified. And the years it was built was interesting because, you know, pandemic times so the windows can open. There was fans. You definitely don't see subways made like this. It was solid. It sounded different when we went. I'm going to play a little bit of a video. But we went on the subway. And the old ads were in there. And, you know, the more things change, the more things don't. A lot of the ads were like, here's Campbell's soup. But here's three-in-one oil. It cleans as it polishes. And then this one was nice. This was a camera ad. The Folding Brownie. Almost a Kodak. So they're just like, look, it's not a Kodak, but it's like almost a Kodak. It's only five bucks. Yeah. Food will win the war. We observe meatless days, wheatless days, porkless days. This is when there was a food shortage, when there was a world war. Can you imagine if people are asked to sacrifice for wars now? Maybe they would change their opinion about going to war if they couldn't get pork. Well, now we all just eat corn all day anyways. Yeah. And then lots of it was war bonds, bioliberty bond. This I thought was kind of neat. They're like, look, Rhine Gold beer is brewed exactly as before because there's provisions. So they're just like, it permits us to produce beer for conversion after reducing alcoholic content to lawful limits. It allows us to sell as is. So they're just like, look, this is the beer you want. It's exactly as before. It's been just really weak, but tasted the same. Yeah. This is exactly as before. Stop asking. Yeah. And then so here's a little bit of a clip that we'll show just to give you an idea of what it was like in there. And that's Ritchie Tick. You can check out the full kind of video that we have in. I think our favorite thing was the fan that was, you know, like six inches above your head. If you stuck your hand up, it would just take off your wrist. Yeah. They're basically, well, it's interesting because like, it's a different, it was a different world. I like progress and I wouldn't want to go back in time there, but you could just tell that things were just different on how safety was handled and the personal responsibility people had. It's like, that's a fan. You're not going to like jump up and like hit your head and blame us, right? Like, so it's just. And it's not one of those slow like home fans. No. That fan is like spinning death. Yeah, it was. So anyways, so we did that. And you could open up all the windows. And in our particular, you know, car, actually all the cars, the rule was vaccination and mass because there's still COVID going on here. So I felt really safe. I thought that was great because, you know, the windows were down. It was a beautiful day. The fans were going. I did say if you stuck your hand out the window, you'd lose your hands. Yeah. The trains are a little bit bigger. So if you, if you put your hands out, you'd lose. You'd lose the handles. It'll just, yeah. Okay. Anyways, good old times. Yep. Okay. But a little bit of three in one oil, it'll ticker right out. All right. I want it. Okay. Jobs.eatafruit.com is where people post their scales or if they're a company and also someone looking for projects, they post up the jobs that are available. So light year, Burbank, California is looking for a full-time engineer engineering laboratory technician. So if that's you, if you're interested in it, check it out jobs.eatafruit.com. Live near LA. Beautiful. Beautiful summers, falls, winters and springs. It's Python on homeward time. Yeah, Blinka. Okay. So if you have not already, please, please, please go to ateafruitdaily.com and sign up for the newsletter. It's ateafruitdaily.com. We have a completely separate site because we never want anyone to think that we will send you a newsletter from ateafruit unless it has something you signed up for is something that you wanted regarding a product. So we did a separate site and that gets delivered to your inbox every single week. We also have it on the web and this week you can check out the Python Developer Survey. See what people in the world of Python are doing. Python 3.1.1 is faster. So I think we might see some speed improvements across all Python things coming up. Some news in the world of the Python Software Foundation. They are adding some more people. We added a link. This is kind of interesting just because of the chip shortage. Google is doing some chip development stuff specifically in the world of open source hardware. So make did a review of our Feather RP2040. Check that out. And then all the normal news projects and more that goes on and on for lots of keyboard projects. Again, I think a lot of people are doing different types of input for their computers so they can kind of customize their experience because they're doing so many different things in circuit Python news. This is kind of the big deal for us right now. So Piley is out. 2.0. And the neat thing about this is you start the app. It pairs with either Clue or with Blue Fruit Express and you're instantly able to look at the projects and within one finger tap the code is already on there. And now we support Clue. So each guide will say if it's compatible with which board and it's the fastest easiest way without a computer to get code onto a device. It's powerful. It's like when you first started using circuit Python and you're like, well, I could just drag and drop a file onto the microcontroller. So this is like that but for wireless. It's very fast. Design to make it a no code easy solution for especially people who want or beginners who just want to get started and they want to do mobile programming. Piley is a good start. Yeah. Okay. And that's Python on Hardware News this week. Okay. All right. Next up, let's do some open source hardware news. Big news. And I'm going to probably try to spend more time on this next week because the news just happened yesterday, I think. And we did a post. It was yesterday, yeah. I've been awake for a while. So it feels like it was two days ago but it was actually yesterday. And I got to scoop. I think Adafruit was the first site to publicize it. So Arduino got $32 million in venture funding. And the two quotes, this is from Massimo and Fabio. So you're wondering what are they doing with this money? Where are they going with it? What's going to happen? What is their focus? So here it is. This is from Massimo. Engineers in Gen Z and Millennial Generations grew up using Arduino boards and STEM programs around the world. And they've become accustomed to the accessibility, simplicity and power of the company's open source hardware, software and cloud services. Now they're taking those demands into the enterprise as they enter the labor force. Next up, the CEO, Fabio. The way corporations solve contemporary challenges and identify new business opportunities, quickly evolving as a new generation of engineers move into the workforce in large numbers. With this investment, we're developing and delivering a new range of dedicated enterprise solutions to ignite this transformation. So it sounds like they're focusing on enterprise and enterprise solutions and corporate environments as their audience and community is now going into this place. So if they're a young kid, they used Arduino, grown up. Now they've got a jobby job and Arduino is staying with them. So we'll see what new products Arduino has. Having that funding is fantastic news for Arduino. Congratulations to the team. I'm looking forward to all the things that they're going to do. I have a request, which is open source got Arduino to where they're at. The company celebrated open source, celebrates open source and continues to celebrate open source. So this is a really good opportunity to show what does it mean to be an open source company and have $32 million of venture capital because there's been previous open source hardware companies that have gotten venture funding. Some have worked out some have didn't but Arduino gets to set the standard pretty much what it is. Because when people think of open source, they think of Arduino. My other request would be for any of the education boards that are open source hardware, may as well open source hardware certifying at OSHA, sorry, OSHA, may as well because that just means it's another signal that these are open source. They're going to be open source forever. And I think that would be kind of cool. And I think it would also reassure folks that all the things that were open source will stay open source. So anyways, congratulations to the entire Arduino team, everyone that's over there. I'm looking forward to all the stuff you're doing and push this state of the art. When Arduino does great stuff, it makes all of us do great stuff. So looking forward to what's next. All right. I goofed on the guides this week. So I forgot to put in one of the images, lady. That's okay. We all literally had one guide. Yeah, but I have a clever way around it. So this is a graphic of the one I, I put the graphic of the one I wanted to show. So Isaac did this amazing guide of all of the HDMI stuff that you can possibly get because there's so many HDMI things out there. It's like USB-C. It's like you're, it's so confusing. Yeah. So I didn't put the graphic of the guides, but I have a way to do it, which is just to go to the screen in here. Okay. Good enough. Yeah. So the only thing though is you'll have to just remember which one is actually put in a guide like right after you post it. So we have a new guy. What's on the big board this week from Drac, who's been doing so many cool retro guides. There's a new guide called on box 86, which basically allows you to run x86 games and programs in emulation mode on Linux computers, which is great for the Raspberry Pi 4 and 400. If you have one, it's nice and fast. So you can actually play. He shows like how to play like Starcraft on your Raspberry Pi, which is like super cool. You also install wine. A great way to take your Pi and play even more games even if they're not natively compiled. We've also got that massive guide from Isaac, just epic multi-page guide on HDMI, the cable types, the like, what does it mean when it says with Ethernet? How long can the cable be? What about extenders? What about passive versus active? How can you convert it to different file format or different connector formats? It's in there. Kenny also did a guide on the QT Pi ESP32 Pico. I think we've got some more of those back in stock. It's an adorable little QT Pi, but it's got an ESP32 chip in it and a stomach QT port and an antenna. It's a perfect little board when you want a classic ESP32, but small. And we've also got Liz did a guide on the PAM8302. It's a little mono-classy amplifier. We've had these in the store for a while, but I realized we didn't have a guide. There's no code, but it's still useful to have like the pinouts and files and all that. We also have a guide update from Trevor and Kenny for Pi Leap, as we mentioned. Pi Leap 2.0 is out. It's a great time to try it. It's right now for iOS, but we are working on an Android version. Okay. Next up, let's do some factory footage made right here in New York City. And it wouldn't be made in New York City factory footage unless you can see what's outside our window. So this is, these are, those are people. And yeah, those are people. And you could see the time-lapse. This is the Disney building. And you could see them putting up the windows. It's kind of cool. Yeah. It's like little figurines. Yeah. It's like those tilt shift things. And then you could see this from the other angle. That is cool. Yeah. Put the skin on. Yep. Okay. It's happening. All right. 3D printing time. Let's show this speed up. I actually like this. This is a really neat homage to some cool Aztec art style things. That's cool. Yeah. And of course, we'll have 3D hangouts come back next week. Yeah. Next week. Don't forget Wednesday's 3D hangout. Okay. Lady, it is time for IonMPI. This week's IonMPI is worth of electronics brought to you by Digikey and Ada Frut. Thank you so much Digikey. Lady Ada, what is this week's newest, latest, greatest? From Worth. Yeah. It's a high worth electronics. So I'm excited because we knew about these. We can talk about them because of course they were secret. But Worth Electronic has come out with a series of feather wings. That's right. You know Ada Frut because we've been making feathers. I actually looked it up. It was Maker Faire 2015 when we first showed off the first few feather designs that we came up with. And feather wings, we had the feather 32U4s and the feather ESP866. And when we published feather, we made the spec open source. Basically, we published it and said, hey, anyone can use this. You can even use the word feather, feather wing, as long as you're compatible. Just don't be a jerk and say it is when it isn't. And what's neat is that because it's been so platform agnostic, you know, if you're going to get a nucleoboard, it has to come from ST. And if you get an Energia board, it's going to be an MSP430. But with feather, we support everybody from, you know, Maxim and N-Long and Atmel and Microchip and TI and ST, you know, and Nuvoton and Espressef and Nordic and everybody. And so it was cool to see Worth jump in and making these accessory feather wings because, you know, Worth, I don't think they have in my controller family. And so this allows them to say, look, as long as you have something that's Arduino compatible and you have something that's feather compatible, you can use our feather wings. So there's a couple. So this is the sensor feather wing. Oh, and I wanted to just point out, sorry, this is the guide for Adafruit Feathers. So check it out. We recently updated it because it lists a whole bunch of feathers as well as our awesome feather wing. It has a link to the awesome feather wing list, which is like a huge community of non-Adafruit made feathers. So the first feather wing, they made four. The first one is the sensor feather wing, which I also physically have here. And it's got pressure, humidity, accelerometer, temperature and humidity. It's also got a quick stomach U.T. It counters on the bottom. It comes pre-soldered, ready to go. So you can just plug it into your favorite feather. It comes with all these sensors and they all communicate over I squared C. So you can pop this onto literally any feather because all of them have I squared C connectivity to add a huge range of sensors from Worth. They also published schematic in the data sheet, which is really handy, which has all the part numbers and there's also the board files as well, though I didn't download them. But basically they published everything. They're like, look, we want you to use this as an eval board and this is a working schematic that you can use. The next board, I thought this was interesting, is this is, so I can enlarge it. I want to remember how to spell it. It's the thion. This is a 2.4 gigahertz mesh network chip. So it's that little module at the end there. And this is what you would use if you don't necessarily want to have, you want to have a low power mesh network. Wi-Fi isn't mesh. If you want to have a sensor node, maybe all these sensors using that sensor feather wing and then you want to distribute data around a mesh network. This is a meshing module that makes it really easy to use. Also comes in a feather wing format and you communicate with the radio module over UART. So all of our feathers also have UART. And then there's an ATECC 608, which is a common encryption private key storage device from at no microchip. And that communicates over I squared C and there's Arduino libraries for that. So between the two of these, you can basically have authenticated mesh networks that have unique identifiers. Also, the schematics are published for this. And this is basically designed to be a dev board to demonstrate the thion mesh module. The next module, I thought this was kind of cool. So this is like this, it's called like a magic power feather wing. And this uses worth electronics makes a lot of power modules. This is a step down module. So you can see those all those capacitors and connectors and inductor in there. And this basically will take up to I think 24 volts input and do a buck conversion, bring it down to five volts and also three volts. So basically if you're using your feather or feather wing in an industrial environment like let's say one of those low voltage trains you were just talking about that run on 32 volts you could wire this up and basically have a train sensor module and you wouldn't have to worry about power supply and it can empower the rest of the feather and the mesh network, what have you. Of course you can also use a lipo battery as all feathers do. But if you want to, you know, we don't currently have a feather wing that will let you take 24 volts and bring it down to five. So this is quite handy to do so. Also the schematic is here. We can see it's basically a power module with an alternate power input. And then lastly there is a Calypso Wi-Fi feather wing. So this is a Wi-Fi module that you can use to connect to the internet securely. It uses UART and there's an Arduino library. So it has AT style command structure which is really common and they have Arduino libraries for it if you'd like. So this uses UART so you can't really use this and the mesh wing at the same time. So kind of use one or the other unless you have two UARTs and you can rewire it. For the most part you just kind of pick one or the other and this is basically how it connects. Basically just over UART you send AT commands to connect, you know, make a socket, connect, send data, open and close it. You can also act as a web browser and then of course here's the documentation for how it's wired up and put together so you can use the Calypso module. And then there is a video. We didn't show the video because it's like 15 minutes long but there is a video on the Worth YouTube channel to check out where they take a M0 feather and they plug it into the Wi-Fi and the sensor feather wing and they basically make a fully interactive post and get web service, web browser. So the web services on the feather M0 connects to Wi-Fi securely with the Calypso Wi-Fi weather wing and then you can read the sensors and set the LEDs so it's read and write with a custom Wi-Fi interface. And if you want to use this again because Worth doesn't make the microcontroller board, you would use a feather M0, a feather M4, you know, an NRF D2840, maybe you want to add Bluetooth and then check out their GitHub repo where they have code for the sensor Wi-Fi and mesh feather wing, that example code for all of them. I mean, they're in platform IO specified format but they should work just fine in Arduino as well. You just have to drag and drop that into your library folder. They are in stock, all four of them, four different types and I can show it on the overhead real fast. So, boom, my Sharpie. So this is the sensor feather wing. So on the bottom, it's got all this documentation. Focus in on it. The humidity sensor has a nice cutout for temperature and humidity so that there's no self-heating. They come with stacking headers, which is great because you can take your feather and pop it on top, especially if you have like a Wi-Fi feather. You won't have anything in the way of the antenna or you can have socket headers and this plugs on top. And then there's a quick connector here. So if you've got your, you know, some other sensor you want to connect or maybe encryption module, whatever, over IceWord C, you just plug it in and you can extend that or of course you can use this to just connect to an existing like a QDPI board if you just want to use this as a sensor module breakout. So that's the worth sensor feather wing. There is a part number, but by the way, it's extremely long. I can't remember it. So just type in worth feather wing and you'll find all them. Hi, on IPI. Okay, before we do new products, don't forget the code is uncased. Make sense in a moment. And you ready to kick off some new products? I'm ready. No, no, no, no, no, no, no, no, no, no, no, no, no, no. No, no, no, no, no, no, no, no, no, no, no, no. So first up, yeah, it's fine. We got circuit playground expresses back in stock. Back in stock. So this is, it's new to you if you've been waiting. Yeah. So we're doing everything we possibly can. And then the code tonight was uncased. And the reason is, is because we've wanted to have something like this for a while. And there isn't a USB drive that everyone agrees on. That's like, oh, here's the open source one, or here's the one that's low cost, or here's the size or whatever. So what we decided to do is just find kind of the best one that has the best price and went through our testing process. I did the test for, you know, I test the speed. And of course I test the, I test that it's actually two gigabytes. The idea with this is really low cost and a standard size that you can kind of embed inside like a 3D printed object or make something special. It's uncased. That it's uncased. You, you, you provide the case. So let's go to the overhead. Okay. So here it is uncased. There's a little indicator LED. This is the control chip, which you can Google to find the part. And then this is of course the flash memory. Another thing that can be useful for is if you're, if you're feeling like it, you could hot air this off, BJ on a separate flash ship if you wanted to like rescue an existing USB key that had like a bad controller. It just has a USB A, but the thing about it is it's uncased. You want a 3D print, you want a mold, you want to do something funky. This is kind of a lump of clay on that. Let it dry. And now you've got a very low cost gift. Here's pet rock on the pet rock is, you know, has some files. You also, of course, we move the SD at the USB connector and solder directly to your single board computer. As I can, you know, it's like two gig of memory, just soldered right on of a flash memory. So I thought it would be kind of cool to stock these and no one Pedro will do a 3D model as soon as they're back from holiday. We'll probably 3D print some cool enclosures for this and then people can take that model and make their own. Yeah, there's a bunch of like really neat things that people print out like they're fans of Star Wars. And speaking of 3D printed Yoda heads and you could put like a little slot in it and then just slide this in there and you could put something on there like the files that it was printed with the STL file. You could put photos on it and maybe a message of someone and give it as a gift. So I thought this was really neat and it's cheap enough where it just doesn't matter. Okay, so this is an encased two gig drive. Speaking of USB. Speaking of USB, we have a couple of USB cables. This is a funky one. So we have a nine volt and a 12 volt boost converter cable that runs off of USB. And I saw somebody was like, can you get one that has both? And I'm like, yeah, there's one that has both. So this is a nine volt or 12 volt. And it's been a while since I tested this sample but I think it also displays the kernel. Let's go to the overhead real fast. So it doesn't do data, of course, it just does power. And this shows the voltage. So if I shorter this, it would say zero volts. And I think on the product page, it's like one amp at nine volts and about 750 milliamps at 12 volts. And then you get a standard 5.5 millimeter, 2.1 millimeter DC jack that you can use to plug into any device with positive tip and negative ring on here. So it's a little more expensive than the individual nine or 12 but that's because it's combo. Okay. All right, next up. So just before we get to the other group of USB things because I wanted to separate them out so there was no confusion. Yeah. What about these? Okay, so we've already got these and they look so similar to what we've already got. You're like, what is this? Why, how is this different than the MyFair tag? This is the N-tag 203. So we've stocked the MyFair Classic tags for a very long time and they're great in everything. But modern phones don't support MyFair Classic because it's an old, slightly less secure RFID tag format. And this is N-tag 203, which is also known as like MyFair, not classic. It's like MyFair Express or something. So these are more secure. They have a longer ID key. They hold 144 bytes of data. You can still use them for all sorts of RFID purposes but more phones and tablets are going to support these chips in the MyFair classics. So we carry the MyFair classics for when people have old technology but if you have a choice, we recommend the N-tag 203s instead. They're more modern. They'll be supported for a lot longer. Okay, now there's a bunch of different types. So I just put one picture to explain what these were. Yeah, so we have four different cables that all look very similar and these are USB PD cables and they're kind of interesting. So yeah, let's go look at this. On one end is a USB-C connector and the USB-C connector will plug into a USB power delivery wall wart. So these are wall warts that you plug into the wall and they have a USB port inside of them. And if you have like a Mac laptop or a really modern laptop, this will look familiar. And then you plug in the USB-C into the wall adapter and then there's a little chip inside the cable. It's like really small and what it does is it tells the adapter, hey, I want you to go into 9-volt boost mode or converter mode or 12-volt or 15-volt or 20-volt and the output will be 9, 12, 15 or 20 volts based on what the PD converter can give you. So let me show you the PD converter so you know what I'm talking about because this is not actually a booster buck converter. Okay. So this is a standard, it's like a laptop charger. It looks very familiar. It's not official Apple but it's very similar looking. So the travel charger gets basically 110 or 200 volts in and then it says output and you see here it says 5 volts at 3 amps, 9 volts at 3 amps, 12 volts at 3 amps, 15 volts at 3 amps or 20 volts at 3.25 amps. So this is a special kind of USB-C converter that can switch what the output is based on what the cable says. So for example, if I plugged in this cable which says 20 volts, you can kind of see it. Let me see if I can turn on the light. Maybe that'll help kind of barely. You can kind of see it. It says 20 volts on it. Then when this is plugged into here, this will output 20 volts. However, if this wall adapter doesn't say that it can provide 20 volts, it's not going to work. So you have to make sure that whatever you want on this cable end, you know, 20 volts or this one says, you know, 9 volts or I have a 12-volt or 15, you have to make sure that it appears on this list because this doesn't do any conversion. All it does is like convincing, right? It'll tell the adapter what it wants on the output, but it will not do any power conversion for you. So if it doesn't have 9 volts, you'll just get 5 volts out instead or you might not get anything depending on how the adapter handles PD. So that said, as long as you're aware of that, it's really handy because instead of having 20 adapters, you have one adapter and then you have a different cable for every product, you can just swap out the cable based on your needs and you'll just get the exact voltage you want. And the output here is 5.5 volts, sorry, 5.5 millimeter out of diameter, 2.5 slash 2.1 inner. And the reason it's 2.5 and 2.1 is the hole is 2.5, but you can see there's a little spring eclipse. So it works with both 2.5 and 2.1 millimeter. And these cables are really chunky. They'll handle up to five amps of output as they have the e-mark chip on them. So a little bit more expensive, but the e-mark means you can charge your laptop. However, just a reminder, because this travel charger doesn't give you five amps, you're not going to get five amps. It'll max out at three amps. After three amps, you know, you'll not provide any more current. So just keep that in mind. Again, this is not a converter cable. It's a convincer cable. It'll convince the travel charger to do what it already does. Okay, cool. Okay. Next up, we have lots and lots and lots of cats. The most amazing, beautiful LEDs. Yes. So these are in the store. These are unique data fruit. And this is from... We may not have chips, but we do have cats. Yeah. And so these are them lit up. We have rainbow ones. And just to give you an idea of how big they are, they are LED size. So they come in different packs. These are made here in the USA. Mark Devink, who is a friend of the company, is a designer, artist, and more. I worked with Mark at Make Magazine. And we're pleased to support a local artist and have all of these. And there's lots of different types. Okay. I like the blue cat. There's a blue cat, cool. But let's show the RGB cat first. Yeah, because that has lots of different things. And the succulents are really cool too. Yeah. The succulents kind of a secret winner. I thought I would just show all these and then you could do the overhead. Yeah. And so that's the cat. And then we have the succulent. Succulent is really nice because you can imagine this being used for lots of cool projects because it could be lots of different light. It looks better than I thought. I was like, wow, it really does look good. And then it wouldn't be Adafruit without a skull. Yes. So this is a red skull. And these are going pretty fast. But this is what they look like. They're beautiful and if you want to up your LED game. So let's take a look at them. Okay. So this one, I'm just lighting these up with a three-volt coin cell. So this one is the RGB cat. So you see a cat and you see the embedded LED. Note that you don't get RGB LEDs. It's one of those, it's called like a flashing light LED. So it changes color. You see from like red to green to blue. So it slowly goes through all the colors. But it's like, you know, you see toys and stuff that often have, you know, necklaces or jewelry that have these little LEDs. So it's a way to add rainbow color without any controller. So that's the RGB LED. And then you want to see the blue kitty. Yeah. Well, this is what it looks like here. But then, you know, we like showing real live demos. Yeah. And, you know, we have all these nice photos we took, but... So this is the blue kitty. It's a nice little kitty. You can see from different sides. So again, I'm just lighting up with a coin cell, but you can see it's so nice at the cat. And then as it's the blue kitty and then let me show the red skull. And here's the photo that we took. And then we'll show you live red skull. You also have the white skulls. So red skull. Okay. And then finally, last but not least, is the green succulent, which I think is kind of the coolest one. Yeah. Is it cool? Yeah. I think it's because it's like, you know, the center is lit up, but then all the little leaves are glowing. So this is, it looks, I mean, it's hard to show on the overhead, of course, but in person, it just looks like a beautiful glowing cactus. Yeah. Okay. And then the star of the show tonight, besides you, Lady Aida, our community, our customers, our team, and this blue cat is... Is the Feather TFT ESP32 S3. We have a much loved ESP32 S2 TFT. Swap out the module with the new S3 four megabyte flash, two megabyte PSRAM, and boom, you've got a lovely two-core, 240 megahertz Tensilica chip with four megabytes of flash, two megabytes of PSRAM. It's got Wi-Fi and it's got Bluetooth and we've got that TFT, Stem-AQ T-Port, battery-powerable, battery monitor built in, you know, low-power capable. You can turn off the I-Squared C-Port even. It's just a altogether wonderful little board and I think it's going to be super fun and powerful, especially for people who want Bluetooth or they need two cores because you get, of course, the extra power. So here's just a quick Arduino demo running. Of course, it's Feather-compatible. It's got all the pins you'd expect so you can use it with your first sensor feathering if you'd like. You've got the reset button and boot button, Stem-AQ T-Port. There's vertical style so if you want to plug in, hold on, always get it in backwards. Hold on, I want to line it up. Boom, you can plug in more sensors and you'll notice as I plug in this sensor, it shows up on the I-Squared C-Scan. So you disappear it and then it reappears. Battery monitoring using the LC-709203 which is a really nice low-power battery monitor. We use that because the ESP32 doesn't have a very linear ADC so having external sensor do it is a good idea. This little module with built-in antennas so you get really good Wi-Fi and Bluetooth support. And I think this will be great for use with Arduino or CircuitPython, especially that two megabytes of PSRM makes it a very good CircuitPython board. You have a lot of memory and it means that you can get Wi-Fi data, do a lot of JSON parsing, control LED matrices, control NeoPixels, control TFT displays. The S3 is a very powerful and a lot of cool peripherals that you're going to see coming out for it. And that is new products. Okay, don't forget the code is Uncased, 10% off the AdFrister all the way up to 1.59 PM. You also get free stuff. We're going to do some questions over on Discord but we're going to do Top Secret while you load up your questions. I have some already that folks typed in, but don't forget Adafruit.it slash Discord. That is the only place where we do the questions. Go there. So let's do some Top Secret and then we'll meet you over in the chat in a moment and answer some questions. So this week's Top Secret, we have some S3s off the line. So it's, you know, you just saw them debuted. So just imagine yourself like a day ago or so. And then we'll show a couple boards. So here's the first two videos and then see on the other side. So Kaleigh, what is this? This is a still toasty PCB panel that just came off the oven right here. This is for the Feather TFT ESP32 S3. We've got this awesome TFT Feather in the S2 format. But this time we've made it and you can see it's got the S3 mini, the N4, R2, sorry, R4 and 2, which means it's got PSRAM, 4 megabytes of flash. So we're going to put, one of them is missing because we're going to do the first article inspection. But if you loved our Feather ESP32 S2 TFT Feather, you're going to really like this one because it's got twice as many cores, more S-RAM, it's got Bluetooth. So nice little upgrade. Coming to the A4 store real soon now. Early date, what is this? Hey, I'm just doing a quick demo for a new product. This is the RCWL 1601. This is an ultrasonic sonar distance sensor. What's interesting about this is this one is in I squared C mode. So it does have a mode where you can query it over I squared C. I've got some resistors here because I built in pull-ups and then I've got it plotting out the distance. I can put my hand up and down to change the output. It doesn't work. I will say one thing about this. It doesn't seem to like to share the I squared C bus, but there's some situations where you don't want to use like the pin trigger pulse style of ultrasonic sonar sensor. You don't want the UART style. Maybe you don't have a PWM input. You have I squared C. And as long as you're cool with just not having anything else on that same bus, like in this case, I've got this OLED on a different bus. Seems to work just fine. Okay. And you published some boards by publishing. I mean emailed it to me so I can post online later. So it will be published. So this really is top secret. What is this? This is an adapter. A lot of people like our Pi zero compatible spy cameras. And they want to use them on a classic Raspberry Pi, which doesn't have the 22 pin high pitch CSI DSI connector. Instead it has the lower pitch, a one millimeter pitch, 15 pin connector. And Raspberry Pi used to create an adapter board that they sold that was used with the compute module IO boards that did this conversion and they no longer sell it. So I just quickly quickly whipped up this little adapter based on the schematics they published. Even though it says DSI, actually this is the CSI adapter only is the camera connector. The display connector would be different, but I don't think anything uses the 22 pin connector for DSI. So basically we'll let you use Pi zero cameras with a classic Raspberry Pi. Okay. And what's this? And then someone asked for a STEMI QT hub. So this is just a STEMI QT size board 0.7 by one inch, which is our standard STEMI QT board size, but it has five vertical STEMI QT connectors on it. And so you could, you know, if you have non-chain non-chaining I squared C, like you're using Grove cables or something or you're just do DIY I squared C, you can use this to basically share the I squared C ports. And that's top secret. Okay. We're going to jump right to questions. I have some lined up. Here we go. Recently my company upgraded security. Good thing, but now thumb drives without security keys are no longer allowed. Also a good thing, but that means anything that has USB on it that enumerates aka run circuit Python won't run. My workaround is to code off a Raspberry Pi, which is also technically programmed from home for now because, you know, they probably can't bring it in. This works, but once I'm gone, if that day ever arrives, do you have any advice on how to deal with this, especially with newer engineers nearly requiring Arduinos to get their job done aka why would I do that in lab view when I could do with an Arduino? I won't hear your answer till I get back from picking up my kids from scouts. So so with circuit Python, you can turn off the mass storage interface. We have a little tutorial on how to do that. That means that you'll have to upload code via the repel, which you can do. Basically instead of using, you know, mass storage support, you would turn off mass storage and then turn on disk writeability. And then I think you can actually still use something like Ampy. I don't see why it wouldn't work. It's it basically creates a file in Python and then you would write to it. So you I think you could use Thani or Ampy. It's it's not going to be as good of an experience, but I don't see why it wouldn't work. The alternative is also just to ask the administrator to pop open that restriction for USB VID PID that's associated with the circuit Python board. So we're eating work constantly. Looking at our security policies as well. So I think about stuff like this for organizations that have lockdown USB stuff because schools don't do that yet. Maybe one day they will. Everything's on the cloud, blah, blah, blah. But what I've learned is everything is a collaboration with the IT security department. So even if USB turns off and you're thinking that you're going to use maybe Arduino only, they'll have to get permission to install that software. Yeah, that driver isn't doesn't come either. You have to install that by hand. Yeah, and you know when someone Googles for Arduino software, there's lots of different places where they might download it from. So you're going to want to do some type of security audit to make sure whatever is getting downloaded. So I think it's a combination of two things. The VID PID lockdown is doable possible. That's what I would suggest is that way you could still have the best possible experience. It's an authorized USB drive. And then the other one is try turning off the mass storage. We have that as a feature for Circuit Python. And then your clean room idea of what you're doing now is programming things on Raspberry Pi at home is OK. You also might want to talk to the IT folks there and say, hey, like if I am able to mount the Circuit Python drives across the network on a secure computer that you authorize so you could plug it in and then those drives are mounted and they can access it across the network, there's ways to do it. Or that one is considered safe. OK, next up. When do you see the Pi storage ending? I don't think it's going to ever end. You should not assume there's any end. I think this is kind of the way our lives are going to be for a very long time where you can't just order something that shows up the next day. And that goes for a lot of things. And then are there any decent low-cost indoor positioning sensor methods? There's ultra-wideband, but it's not inexpensive. Basically, no. Indoor positioning is extraordinarily hard. It's a very, very hard technical problem. Most people don't realize how hard it is because outdoor, there's GPS and GPS is very cheap. But GPS isn't, even if you did work indoors, it wouldn't be precise enough. And also, of course, it doesn't work indoors. So yeah, there really isn't anything other than ultra-wideband. OK, do you have an end with the Wittern folks? I love their USB analyzers, particularly the U3. It's pretty amazing. I would love to see someone in US Carry. It's the people I recommend. Don't have to go to AliExpress. And they link to them. Do you ever hear of these? We buy enough stuff when we contact a company that they do talk to us so I can actually get samples because I'm like, hey, when I order, I'm going to be ordering like 1,000 cables from you. So I'll probably be able to get those things. I'll ask them for samples and check them out. OK, there's a new agreement on smart home control called Matter. Have you considered becoming a member? And in general, can you share what involvement would inquire? Just hoping a maker like Adafruit would contribute to what is important for makers. No, we just did thread and now we're already on to Matter. So here's what we would like to do. So usually we don't get invited to those types of groups because we have the Internet of Things Bill of Rights and if someone Googles us, they're like, oh, like, you know, home control, it allows voice storage across the cloud. By the way, I didn't get a chance to write about this, but Sonos has a non-cloud, non-voice storage speaker. And the advertisement for it is like privacy first. I think that's going to be a trend that we see. We always think that if something can listen to you, it should have a mute button or a physical off button. Amazon added that to some of their new Alexa's. The Alexa Show has a very large physical button that you move now that it's cameras off. Mute is on, which is an interesting thing because it's the opposite. Mute is on. That doesn't mean the sound's on. It means the sound's off. I'm sure they use some logo that makes it clear. Yeah, anyways, so that's kind of cool. So we would like to consider doing something like that, but usually what we like to do is like, hey, if it's collecting data, that should be downloadable by the user. So we kind of come in with user rights and baggage. So we don't get invited to these parties, but we would like to look into it. We'll see. So if we do, I'll let you know. Any news on the ESP32 S3 BLE HID? The best bet is to ask Espresso for that. I don't have any control or updates beyond what they announce. All right. And like ESP, they're like LEDs. Can you do wireless circuit python integrate with Jupiter? Would like to be able to use that as a ripple wrapper? Yes, eventually. I think we're working on a web flow and web workflow and that you would probably be able to do with Jupiter. Although we're kind of targeting just using like a web browser to start. Okay. Do you see the Adafruit ESP32 S3 TFT working with the M1 Mac without too much frustration since it has new native USB support? Any insight, Adafruit? I don't see why I wouldn't. I mean, we haven't had any issues with M1 Macs for ESP. We're only using M1 Macs for testing and so far so good because it's super fast and I really like my M1 Mac. I think it should work just fine. I mean, I haven't heard of any issue. It uses the built-in CDC drivers. There's no custom driver. And the WCH chip drivers also work fine on a Mac. I mean, you have to turn on allow me to install non-official software. But once you do that, it works fine. I found that the thing that starts to come up with all these things that are USB that can be complicated, sometimes people go through a hub. So they have a hub and they put all the USB stuff in that. That's when things can kind of get a little complicated. Okay. Them's the questions. Yay. All right. A lot of questions. Thanks, folks. So that's our show for tonight. We're out of here. Thanks so much, everyone. Don't forget the code is UnCase. This is my hands doing nine o'clock. It's nine o'clock. Ding, ding, ding, ding. Yeah. Nine. Special thanks to Zay behind the scenes here at Adafruit in our Slack channel. Take care of all the customers and more. Special thanks to the community. All of our Adafruit team, our customers. Thanks for supporting us during these ups and downs and topsy-turvy times. We very much appreciate it. And we will continue to do good, be good, be open source, share. The light of our candle, if we light other candles, doesn't diminish our light and flame. I think about that phrase sometimes. So it's always good to see other people show and share stuff and then see other people show and share and encourage and encourage and encourage it because that is how civilization was built and can continue to thrive, sharing and uplifting one another. So we'll see everybody next week. Here is, oh yeah. This has been an Adafruit production. Here is your moment of Xenar. Okay, everybody.
