 Life in New York, it's Ask an Engineer. Hey everybody and welcome to Ask Engineer. It's me, Lady Aida. With me, Mr. Lady Aida. We're here at the Aida Food Factory. That's the real background. This is what we do of our manufacturing and kitting and shipping and designing and videoing. As we're doing right now, we've got a jam-packed show for you. One hour of the latest news in Maker Hacker Artist Engineer news and more products, videos, tutorials. It's all here plus some cool retro stuff. What's on tonight's show, Mr. Lady Aida? On tonight's show, the code is WizKit, 10% off in the Aida Food Store, all the way up to 1.59 p.m. Or if I crash out and I fall asleep and don't turn the code off, you might be able to use it a little bit longer. But load up your cart now and don't forget to save 10% off. It supports us and open-source hardware company manufacturing here in New York City. Talk about some Aida Food Live series of shows that we do each week, including Show and Tell. We just did that a few moments ago. Time travel, look around the world makers, hackers, artists and engineers and more. Rich or Tech, we got a bunch of cool things that we've been sharing online. Some things that'll bring back memories and then some things that a lot of people haven't even seen before. From the mail bag, your letters, tweets and more to our team. We read those. Help wanted some jobs from the Jobs Board at aidafoodjobs.aidafood.com. You can post your jobs or you can post skills you have and we approve all of these to make sure it's all legit and check it out if you want to either get someone amazing to work for your company or your organization or your project or post up your skills. If you're looking to get out there in the world and do some projects with people. Yeah. Have some main New York City factory footage, some 3D printing, eye on MPI, new products, top secret. We answer your questions. We do that over on Discord, adford.it.discord where there's about 33,000 of us. We're all friendly. 24-7. Hang out there even when we're not live. Yeah, you have 33,000 friends when you join there. All that and more on you guessed it. Ask an engineer. Okay, first up before we do some show things, I wanted to give some folks some updates and obviously we live in the world so we should talk about some other stuff. So as of right now as you could see we're not wearing masks in New York. The protocols are starting to change. We're completely alone here right now and we're able to not wear a mask. We also live together, vaccinated. Our team is still wearing masks in all the different common areas and then depending on the situation where they're at, what they're doing, they're making smart decisions and taking off the mask. It's time. We went to a concert. Things are starting to change pretty rapidly and the numbers are looking pretty good I think in New York City. The positivity rate is like almost under 1%. We're inching closer and closer and closer. It hasn't been this low since like July of last year. So for folks that are trying to figure out what's going to happen next or if you're running a business, we're in New York City and it's been really challenging for the last couple years but the direction is still going in the right way. Just wanted to let folks know things are going good and we're looking forward to this being a chapter that we got through in the best way possible together. Next up, New York City right now as you can imagine because we have the largest Ukrainian population in the world besides Ukraine that might change because of the refugee situation soon. This was Washington Square Park. We went to a peace demonstration. Folks got together and basically wanted to say, hey, we don't want to be invaded. So we don't know what's going to happen and we don't know how this is going to affect things but obviously this is a good example of how we all need to advance the cause of peace, building things together, sharing good values together because this is going to be a thing that is going to affect all of us very soon. One of the things that I thought I'd mention is this show that you're watching right now is powered by a Ukrainian company, Restream.io. They have two locations, one capital of Ukraine and they've been working to get their employees out and help them and then Austin, Texas. So if you want to find out more about a company that if you're watching Ask an Engineer, you're watching something that has a big impact on some people's lives. So they put together a good resource page over on Restream. So just go to Restream.io and let me go to the computer over here. For resources, especially for the humanitarian efforts, that's where I think we're all going to be able to have the biggest impact. Check out the places you can donate, the relief for families that are going to other locations that you're creating in Red Cross Society and I know that there's a lot of caution that you should have if you're going to donate money or figure out what you can do but these folks for sure are on the ground and they're doing what they can to get the word out. So that is what's going on here. We'll continue to provide updates and more as we have them but we're all hoping for peace and it's not good. So let's kick it off Lady Aida and start the show. Like I mentioned, Wiscit is the code. If people are adding things to the cart, they get free stuff. That's right, we're still doing freebies and you order from Adafruit.com. $99 or more, you get a free perma-proto half-size breadboard. It's great for making your projects permanent from a solderless breadboard. $149 or more, you get a free stemma QT board. We have various sensors and devices available and $299 or more, you get, sorry, $199 or more, you get free UPS ground shipping in the continental United States. Okay, we have a live series of shows that we do every single week. We just finished one of our longest-running ones, Show and Tell. We were on the Show and Tell this week, Lady Aida. We had a bunch of folks on the Show and Tell, but I'm going to make a suggestion. Folks should watch it after this show, of course. Check out any of our channels. But there is Paint Your Dragons Book Club of the Month. That's what I'm calling this. And it was about Pixar and it was the biography of the founder of Pixar. No, the biography of the pixel. The pixel, sorry. I thought it was, sorry. He worked at Pixar. Sorry, he worked at Pixar. And so he worked on the pixel. That's right. Sorry. I'm getting my Pixar's and pixels confused right now. But it was really neat because he had, yeah, because it was all about the original formats like what is an alpha channel and how things like Toy Story eventually came along. But I thought that was really neat. And then I showed off this pop-up book. Because I said, if Phil Beach has a book, I'll show a book. This is the book that I showed. This is inside the personal computer. And it's a pop-up book that has a bunch of retro computer things. Well, the retro now at the time, maybe they weren't. And a really good explainer on how computers work and more. It's still relevant. And then this is my favorite page. This is the one with the Fluffy Drive. And then the last page has- I have to show the floppy disk. You want to show this? Hold on. I'm just going to grab it carefully. It says hard to remove as a normal floppy disk. Yeah. All right. Fluffy disk. And then there's floppy disk there. And then this is cathode, how that works. And then this is a printer. I like this one. So anyways, check that out. Good book recommendations on the show this week. Desk of Lady Aida. That's a show that we do every single Sunday. Correct. Lady Aida, what was on the show- And sorry, what was on Desk of Lady Aida, part one this week? Well, I showed up. I've been working more on pie camera stuff this weekend. And that's a ESP32-S2 board with an OB-5640 camera and a TFT display. And some buttons so you can take photos and save them. And I demoed that. We also showed up. We're working on the Atari video machine. Atari video music machine. It's kind of cool old 70s retro stereo system addendum thing that will create cool visual effects based on audio input and RF input. And I just showed how I changed that to be NTSC. Okay. Then we have the great search and the great search is when you use all your powers of engineering to find things on digikey.com. What did you look for this week? Right. So what I want to do for the Atari video music machine is I want to change it from being NTSC to S video because S video will give you slightly better color quality because the color is separated, the chroma is separated from the luma. Color and brightness are on separate channels. So I went and showed how I got a perfectly fitting panel mount S video connector. So it'll replace the RF connector because like almost no monitors these days have RF input anymore. It's very, very rare. So we removed the RF cable in a way that you can be, of course, replaced later. And we're going to add S video output, which will be converted to HDMI. All right. And then we had JPE's product pick of the week. We do that on Tuesday. That's where we broadcast live inside the product page. And you get a discount automatically. You don't have to put in a code or anything. Here is this week's highlight from product pick of the week from JP. Seven segment Stema QT backpack. It has that HT 16 K 33 multiplexer there that deals with all of the pins of all these many, many LEDs. And then you get to talk to it right over Stema QT. So here you can see I have one. This is the red. And then I've put a little bit of a diffusing gel over it. So here this is actually scrolling the IP address that this little QT pie with its little antenna there are picking up on my router. So I flash all the lights on, off, run a little animation a few times, say IP address. And then I'll blink a little bit while I'm waiting for that to come up. And this is actually a routine. This blink routine is built right into the library as well. So now once it once it grabs that address, it kind of scoots that other. So the character's off there and just starts running my address on here. The four digit seven segment backpack with Stema QT. Okay, JP's workshop is tomorrow. And JP sent me this video right before our shows. This is a cool thing that you can do with if it's the ESP 32 you could do with PS RAM video out. Yeah, so check this out. Is there anything the ESP 32 can't do? It can do anything. Just weirdly. All right. And then we also have a CircuitPython Parsec. We do these every Thursday. Here is the latest one. For the CircuitPython Parsec today, I want to show some more display IO stuff. This time it's going to be positioning. I've got this little pill shape. This is actually a round rectangle. And I've set it up on this OLED feather wing so that I can use the A and C buttons to slide this left and right. Move that around kind of like a little paddle in Arcanoid or breakout. And I can also hit the B button to reset it. First of all, we're going to import some libraries including the display IO library. And in this case, the display shapes round rectangle. Then I set up the display and I create this object right here. The round rect is a round rect. And I position it at zero and a particular height, as well as a width and height of the object. I'm driving those from the display itself. So this is somewhat portable code. And then I'm setting this to have a radius of eight around those corners. I fill it black and put a little white outline on it with a stroke of one. Then as I, in the main loop of the program, adjust buttons, we're simply changing the position. So I have a variable called xPause, and I'm either subtracting from it or adding to it. And then I'm updating the object with this line right here. RoundRect.x equals xPause. So as that x position changes, so does the position of the round rectangle. The middle button here sets this to be the center of the screen. And then the button on the right adds to it. And so that's a really simple way to use the x positioning on an object inside of display IO to move things around. And that is your circuit, Python, Parsec. All right. And then on Friday, Deep Dive with Scott. This is the last one Scott's doing. Well, he's on fraternity leave. So Tim Fomega will be taking the reins for a little bit. Well, Scott's out. So tune in on Friday, 2 p.m. Pacific, 5 p.m. Eastern. I'll win AMP every week. Fomega's out. There's a lot of it. All right. Time travel. All right. First up for time travel. Just a little bit of reminder. We should be shipping eight a box soon. We are subject to the same part shortage as everyone else. So we're calling this a winter spring edition. Thanks for your patience, of course. If you want to drop out, that's okay. There's a lot of people who want to get into that slot. But we also appreciate that you're waiting as parts come in. And they are starting to. It's just a little slower than everything everyone on planet Earth would like. But no surprise, I'm sure everyone's aware of this for all the things that they want and need. There's always a little bit of a delay right now. This is Women's History Month. We just wrapped up Black History Month on the site. And we got a lot going on on the site. So if you check our blog, Adafruit.com slash blog or blog.adafruit.com, you can look at a few things. We have a Celebrating Women Maker Guide. I want to go to the site and let me try to get here. It's Valentine's Guide. We got a lot of things celebrating women makers. So you can see that here. You can go to our blog. It's one of our featured blog posts. And if you want to support women makers, you can check out the guide. And not only look at the Learn Guides, but you can look at products that we stock from amazing women who make and sell electronics, book authors, and more. So we'll have blog posts every single day. And if there's someone amazing who happens to be a woman for Women's History Month, just send this email. And we'll get it up on the blog. Mail bag. All right. Pack the mail bag is here. And this week, yeah, well, this week, I thought we would do a tweet. So we get emails. We get form posts. We get sometimes people leave us voicemail messages, but I try to mix it up a little bit this week. This is from Kevin. Kevin says, the Adafruit Learning System is literally second to none. I recommend anyone who wants to learn robotics, electronics, and programming. This is what world class looks like. Thank you, Kevin. I kind of like that saying second to none. Second to none. Because second to none is one. So it's number one. But why say that when you can say second to none? All right. Every single week, usually seven days a week now, we're publishing a bunch of retro tech stuff. So this is stuff from the past. Most of the time is technology. Sometimes tomorrow is going to be a little bit of a different one. Sometimes, yeah, science fiction related maybe. But we show these so you get inspiration on how things used to be designed or how electronics has changed. Or maybe you had one of these things when you were younger, maybe someone told you about it. Or you just want to think about designing something so it's not just a black rectangle. And this week, we have a few things. This is a very weird and rare Nintendo keyboard called the ASCII. And it looks fake. It looks fake. And it was only for like one specific game. And it works with the GameCube. And this is a full-on keyboard. And a game controller. It looks so heavy. That's right. I got the little trigger knobs. We could have had this as our future. Well, it's still not too late. So you could check it out. We also posted photos of the packaging. I think the packaging from the 90s is also really neat and how things were made and displayed. Next up, we have the Coleco Zodiac astrology computer. I posted up a preview and I said, what do you think this is? And the folks said, it's a star gate. It's a handheld star gate. So what this does, you enter in your birthday, your information, and then you get your horoscope. Comes with a book. And we have a full blog post on how to use it along with the history. And Sidney Omar is the astrologer behind this. So you can read all about it. Wait, is that Sidney in the middle there? And I know. And we also have a commercial from the 80s in it. So check this out. Mattel made a competing one as well. So that's kind of neat. You just don't see electronics that look like this anymore. I love Coleco because they're like a leather company and they're like, but we're going to get into computers. We actually made some good stuff. And speaking of unique form factors, I previewed this a little bit. This is the Defiant from Deep Space 9 CD player. And the best thing to play is, of course, the Deep Space 9 original soundtrack. So you listen to it with your Starfleet issue headphones. And here's a little bit of a video. Then we posted up a, guess what this is? We've been doing this each day. So he said, guess what this is? And usually it's a close-up of the photos that we post a little bit later. This is the Polaroid Onyx, special edition, clear Polaroid camera. Look at this bitchin' camera. There was a time and place where, if you wanted to do something special and show your technology off. It's not even clear. It's like that weird brownish clear. That's right. That we really don't make stuff with this tint. You had one of these when you got your DeLorean. This was, yeah. And so this is the Ox. It's a shade. It was an anniversary edition for the Polaroid. Really cool. And it just goes to show you. You don't have to design things that hide all the electronics. You can show them proudly. Lady Gaga should have just re-released this. Yeah. Well, yeah, she was just for those who were running the reference. You know, Polaroid is kind of more of a holding company right now. They licensed out the brand. So for a limited period of time, I think they had Lady Gaga as the creative director. I don't think anything came out of it. The other thing is this is the Box. Polaroid Spectre System Onyx. And this is a hologram. Back when we used to put holograms on things. It's so futuristic. Yeah. So it gives you a little, you know. Well, is that like some sort of weird ray trace thing in the back? This is the box that came out. No, no, inside the box. What's that? Like weird. It's a photo. Yeah. Yeah. Of the future. Yeah. So tune into the blog and social media and all sorts of places where we post content and more. And you'll see more of these things. Just look at this. It's a beautiful. Gorgeous. Beautiful camera. Okay. Okay. You can go to jobs at adafruit.com, poster jobs up or poster skills this week. There's a few, but I just wanted to post up this one. This is from Six Paths Consulting. It's remote and it's consultancy on a power monitoring project. So if you've ever used any of Adafruit's hardware, do power monitoring. Guess what? You probably could do this job. All right. Python on hardware. Time late, Ada. I'm ready. All right. We have a bunch going on in the world of Python on hardware. First up, I guess big news is Moo. 1-1-1? 1-1-1-1-1-2? 1-1-1-1-1-1. 1-1? I don't remember the exact version, but it's out. It is out. There's a neat little making of Moo video. But if you go to the Moo site, and also I'll go here, you could check out all of the new features, updates, and more. Nicholas posted up a video. It's a little bit of a time lapse. It has all of the contributions over the years. Yeah, I'm in there. Yeah, and you could see all the people in the faces because software is made by people. But there's fixes, there's updates, there's more language translations in there. So if you're using this, check it out and onward to Moo 2.0. I know a lot of folks out there are using it. Moo is such a great beginner IDE. Yeah, it's our favorite one. Circuit Python 7.2.0 release, so far so good. We haven't had any bug reports or really anything, so we think this one's really solid. 7.2.0 is up. Door, please download it, try it out. We do have ESP32, S3, S2 support in there now. Yeah, S3 and C3 is coming. We're still fixing a lot of bugs, updates. Keep posting up your issues because we're squishing bugs. Whenever we add more capabilities. But Async is really well supported now. So if you want to do concurrency processing code, please try out Async and let us know how it goes. Okay, that was often asked for. Then we celebrated 10 years of Raspberry Pi. Wow. 10 years. It's been a decade. I remember when we decided to stock the Raspberry Pi. I remember the first time. I knew where we were when we decided. 10 years goes by pretty fast. Also very slowly. Yeah. Check out the blog post on raspberrypi.org, the interview with Evan. And I think one of the things that you've said about it is, it is one of the things that really popularized Python. Because a Raspberry Pi, the Pi doesn't just mean for Pi. I mean Python for hardware, this is, you know, this was an essential part of the circuit Python journey as well. Because we had been doing before circuit Python on MicroPython, we had been doing, we had ported our libraries over to the Raspberry Pi, so that people could use the hardware that we'd originally written in Arduino. We would port it over to Python. And so starting the idea of having SPI and I2C bus support and how to like talk to registers in Python. And a lot of that stuff got turned into circuit Python the way that circuit Python works for us. So it's all been one big story and trying to make everything break cohesive. All right, and then congratulations Paul for launching circuit Python show. Yay. So episode one is with Katny. I wanted to play the trailer, and then I'll see you on the other side. The trailer is only 15 seconds. Welcome to the circuit Python show. I'm your host, Paul Cutler. Each episode I'll be in conversation with someone doing something with or near circuit Python and its community. In this first episode, I'll be talking with Katny Ramor. Katny is a mentor, maker, open source community leader, technical writer and embedded software developer. She's sponsored by Adafruit to work on circuit Python. And you can watch it on YouTube if you want to. You can download it with your favorite. Do people still call them pod catchers? I don't know if they call them, I did. And you can also subscribe to it on YouTube. You can watch it. You can listen to it. You can use Apple. You can use Spotify. You can use any of the pod catching tools you want. And then I think the upcoming one is Les, who writes it. Les Pounder, yeah. So he's magical collection of boards. Yep. And if you want, you can go to circuitpythonshow.com. Sign up for newsletter, get the episodes latest, learn about it, all that and more. If you want to be a guest on the show, go there and you can even send your info in. Probably talk about some cool stuff you know on circuitpython. And that is Python on Hardware Newsletter Recap this week. Yay. Blinker, blinker. Okay, Lady Atta, we're an open source hardware company. It's true. We do lots of things and one of the outputs is open source hardware to prove it. We post up our code. We put it under a license that you can share. We also do a bunch of learning guides. We have 2,630. What is on the big board this week? Okay. So guys, this week JP wrote a touch tone phone dial-a-song. This is kind of neat because using, I think, a RP2040 feather to read the keypad on a phone without making it so it's like damaged. You can always return it back to its old state. And then hooking into the speaker. So when you pick up the phone, it detects that the phone's picked up and it plays a dial tone. And then it plays the tones as you press the keys. All this sounds like not hard, but it actually is quite challenging to do. And when certain phone numbers are dialed, it'll play a song. So it's like separate from the phone system, but it feels just like a normal phone. So it could be really fun for art projects or installations or just if you want a phone to call up and you don't want to call anybody. We also did a guide on flippy floppies. If you have a standard TEC 5.25 drive, you want to use it to read flippy disks. Jepler wrote up a great little guide on how to use one of our optical sensors to self-detect the index pulse. And what's neat is that he has a little 3D printed case with a switch and you can just flip back and forth and you don't need any special software. It just magically works as a flippy disk when reading it with a fluxer. Liz also wrote a massive guide on MIDI for Makers. Check it out. It's like everything. It's got great examples. For MIDI on various boards with USB, with UART, with BLE, inputs, outputs, buttons, potentiometers, you got it. I think we added a note to the feather sense. I think maybe it's because it's got a SPM bug in Nordic SDK. We documented that. Noam Pedro did a fun sketch drawing toy with Circuit Python, which is similar, but not exactly the same as another etcher and sketcher type toy, which you may be familiar with. But this one is on Circuit Python with TFTs and colors. And also more updates to the feather ESP32 S2 TFT feather guide. All right, let's do some New York City factory footage. And it wouldn't be New York City factory footage without a view outside our front window. This is Disney. This is the new Disney hotel that everyone's talking about. Welcome to the Disney Hotel. This is the Star freighter. This is right. Actually, this is the... This is Death Star under construction. Do you want to go back to when we made the Death Star? That's right. Family packages are available. DeathstarDisney.com. Okay, let's do some 3D printing stuff. All right, we got two videos. We're going to play these back to back. This is the sketching thing. Sketcher, sketcher, sketcher and etcher. The sketch like entity. And then we're going to do a cute speedup that has this little robot that goes down a ramp. Take it away now, Ampager. Hey, what's up, folks? In this project, we're making a sketch drawing toy with CircuitPython and 3D printing. We thought it'd be fun to make a simple sketch drawing toy using the Feather M4 and a 2.4 inch TFT featherwing. We designed a snap fit case to house the electronics and added a rechargeable battery to make it portable. The TFT featherwing features extra header pins so the wiring is relatively nice and neat. It's running CircuitPython and uses the display IO library to draw pixels on the TFT display. You can use the two knobs to move the cursor up, down, left and right. The toggle switch lets you do a pen up and down so you can turn off drawing to make separate shapes. Clearing the screen is done with a simple press of a button. The code for this project was written in CircuitPython by Carter Nielsen. You can easily customize the code by changing the values in the user config section like the background color or the sketch scale. We think it's a great jump off point for folks who want to add more features or if you're just getting started. CircuitPython makes it easy to jump in and get your projects up and running. I designed the case in CAD and used several models of the electronics. 3D models of the feather and the display are available to download so you can use them in your projects. Be sure to check out the Learn Guide for full tutorial on building your own sketch drawing toy. We hope this inspires you to get started with CircuitPython and make fun projects. Thanks so much for watching and be sure to subscribe for more projects from Adafruit. Before we go into INMPI, just a reminder, with Git's code, we've got to pay bills sometimes. We use regular old money, too. They're not taking pictures of... pigeons and penguins yet. We don't have any of those, anyways. But please use the code and you save some stuff. Ten percent. On everything in the store. And you get free stuff, too. Okay, let's do INMPI. That's right. This week's INMPI is from Challenge Electronics. Yes. Lady to what is INMPI this week? I'm always excited to have a new company to feature on INMPI. Not that I don't love the maxims and the analogs and TI's, but I also like to support and promote the smaller companies. And Challenge Electronics, they make piezos, speakers, boxes, enclosures, battery holders, and stuff. And they're in upstate New York. I know. While they're in New York, at least. So this week's INMPI, they're a series of waterproof battery holders. And check it out. It even says on it, waterproof battery holders. These are IP65 battery holders in a couple of different configurations. So we stock battery holders like this and the Adafruit Shop. A lot of electronics these days are sealed rectangles with a built-in LiPoly battery and charger. And that does make them usually less expensive, harder to mess up. But it also means it's really hard to change at the batteries. You know, if you have an old phone and you have to change at the battery, you usually have to go to like a specialty place or you like put it in the microwave or like the heating thing in the microwave and remove it. But you know, if your product or project uses AA or AAA batteries, it's going to be a lot more field or user replaceable, which could be important. Also the leakage on an alkaline battery can be a lot lower than a LiPoly battery. So there are definitely times and like lithium batteries work very well in cold temperatures. So there's definitely times when alkaline batteries or sorry, AA AAA batteries are the way to go. The only problem with these open battery cases is they're inexpensive, but it's easy for dust and moisture to get in. And so this is actually a batter corrosion because the battery is corroded. I found this photo on Flickr. But the idea is similar. You know, water gets in, you've got these contacts, they're metal, there's metal on metal contacts that they get oxidized, they get damp, they get dirty, and then the batteries make bad connectivity. So not good. Also, usually the contacts are another way to get water into your electronics. So what if we had a battery case that was more waterproof? So this is the CAB series. They come in two times AAA, two times AA and three times AA. All of them are IP65. I'll show them on the overhead in a little bit, but they've got four screws and they've got red and black cables coming out about six inches or eight inches there. And to remove the batteries, you unscrew it, but the whole thing is IP65. So it's nice and durable, good for your dust-proofness or waterproofness. And here is the Ingress Protection rings guide. So one thing to note is that IP65 is dust-proof and good against jets of water, but it is not good for or dunking underwater. So this isn't like for your pool, but this would be good for outdoor, you know, something that's in the weather, basically, something that has rain, you know, jets of water are coming at it. Let's say you want to make a Lora sensor node and you want to transmit data only once in a while. You want a battery powered off of AA or AAA, so people can come by every month and replace the batteries. It's user or field replaceable. This would be a really good battery pack because it could be outside, nicely protected, and very easy to open up when you need to access the batteries. Come in multiple sizes and they're all in stock. So you can actually... Available on Digikey. Oh my gosh, things are in stock. This is what is the challenge for a lot of things when we want to showcase them on our shows now because one, sometimes they're really popular and not in stock. Sometimes it's our fault. People will say, I really want that and then they buy them all up. But this time, this is a new company that we're spotlighting. Yes. So let's go to the overhead and I'll show it off really quickly. I just want to show how this is put together. So this is... I have one of each. This is the two AA and this is a three AA. So you open it very easily. You just use a Phillips screwdriver to open it up. I like the four screws because it really... I'll show the gasket inside. This makes really good contact and they're nice stainless steel machine screws as well. And then you can see here, there's this little rubber gasket. So this part has a lip. You can kind of see here. There's this... kind of tough to see. It's so small. There is like a little lip here. If you can see that. And actually, it's a little easier to see on the bottom. See this little lip here? This little groove. This groove fits into this groove here, which has a rubber bit inside. And it's a solid piece of rubber that goes all the way around. And that's what gives it that protection as long as you screw it down. The lip bites into the rubber and the rubber is what makes the seal. So if you're going to get waterproof stuff or weatherproof stuff, make sure that it has a rubber gasket. You know, it's not enough to just use plastic overlap. That's not water, jet or dust safe. But these look very well made. Really nice. Good contacts. Good spring even says challenge on the inside. And if you need a custom sized one, they think they do them molding here in New York. They can probably hook you up. So quote them. If you need a diesel or nine volts or maybe you want four times AAA, they can make a custom one for you. Okay. And that's this week's INFPI. Okay. We're going to do new products before you do new products. Don't forget the code is this kit. You can start loading up part now. And don't forget, you get a bunch of free stuff the more you add to your cart. Okay. Are you ready? Lady Ida. I'm ready. All right. Hit it. All right. You're probably wondering why the code was whiz kit. But here's why. Yeah. So this is a kit from, it's called the RFID whiz. And this is from Smooth Technology. And so with technology, actually the main designer used to be an Adafruit Peep. So it's great to see folks going off and design their own kits and then we get to stock it. So they do a lot of escape rooms and installation and art exhibits. And there's a lot of things where it's like you want a card that will turn something on or off. Like it's like when you touch something to something else, something happens. And if you know or do we know, yeah, it's not too hard to code up. But a lot of people, they don't want to do all the wiring and the relay and the protection circuit and all that stuff. So this is a board that has an AT tiny on it. And you can see it plugs into, the red board is an RFID reader. And the blue button is the program button. So what you can do is you hold a card over it and you hold down the learn button. And it learns about that card. And then you see when she moves the card back and forth, the green light indicates and you can't hear the relay because it's a GIF, not a movie. But the relay is turning on and off. And so it's really, really easy way just power with 12 volts. You get a relay out. The relay can do I think 240 volts up to maybe, yeah, 250 volts AC up to 10 amps. So you can control pretty significant equipment with it. And basically you use this for our projects, installations, museums, escape rooms, you know, automation side of your home. Yeah. And on the product page there's a couple videos that are linked in the photos. Just click through and you can see both of them that put together some really good videos. Yes. Next up. Okay. Next up, we have a stem acutification of the ADXL343. So this is a revision. This board is still red. This was a collaboration project between us and Digikey and analog devices. Before they, no actually I don't know devices, still I don't know devices. Just why it's red because ADI and Digikey both like the color red. And this features the ADXL343. It's very, very, very similar to the ADXL345. But it's very affordable. Now comes in a Stemac QT format with two Stemac QT ports. So it's plug and play. This is a great solid triple-axis accelerometer. I really, really suggest this for rock solid performance. You don't get weird flaky behavior. It's like tried and true. This is like a decade old or more 15 year old accelerometer chip for analog devices. So it's well established as I think 24 and 16 plus or minus G. It's on the back actually. Yeah. So plus minus 248 and 16G. So good for every all around purpose accelerometer ring. All right. Next up. We've also got a new revision for the ESP32 S2 QT Pi. This board came out. It was good, but I made a little mistake on the low power mode for deep sleep. It's been fixed. I also rotated the antenna. So it's pointing out and get like 3DB better game. So, you know, more game is better game. Otherwise it's the same. So it's just upgraded and updated. It's adorable. It can run Circuit Python. It can run Arduino. It's got four megabytes of flash, two megabytes of PSRAM, all inside that little chip. So a great little board if you want to have a miniature Arduino or Circuit Python, Wi-Fi capable microcontroller that's like fingernail sized. All right. And the star of the show tonight besides you, Leigh, and our community, our customers, our team here at Adafruit and everyone who helps run the shows and all the things here. And more is. Yay. It's a TFT. People love TFTs. This is a 1.9 inch IPS TFT, which means it's very visible from all angles. It's truly a rectangle. I know we've done a couple round rect displays, but this is a rectangular display. It's 170 by 320 pixels. So it's quite a few pixels. It's kind of kind of a long, longish view, but could be useful for some people. It's got four mounting holes and pads on the bottom. You can solder it into a breadboard like this and wire it up. And then you can use it's running the ST7789 chip set. So you can use it with Arduino or circuit Python. Honestly, the ST7789, it's so popular now. Pretty much anything that supports a TFT will support this TFT. Just have to set the width and height. On the back, it's got a micro SD card slot. So if you want to use that to store like gifts or images or animations or whatnot, you can do that. And that's also an iSpy connector. We're going to be doing more stuff with iSpy, but we're getting started with just making sure that all of the boards that we ship have this connector. So people, it's kind of like a STEMF or SPI displays make it very easy for people to snap open and connect a TFT without doing all the breadboard wiring. All right, you want to shut off? Yeah, I thought I could shut off real fast on the overhead. This is it with a SAMD21 QT Pi. So it's a nice, crisp display. As you can see, it's IPS. And so it's very visible. You don't get any of that color. You know, I mean, it gets a little darker because it's not as close to the camera. But it doesn't have color distortion up to plus or minus 80 degrees. Full color display, I don't know. It's kind of nice. It's a nice little size. You know, 170 by 320 pixels. It could be good for like a little text output or a control interface. Okay, and that is new products this week. No. Okay, I'm going to do the code again. Always good. It all makes sense now. Yes. All right. Let's we're going to show some top secret. But while we're doing that, load up your questions in the chat. Advert.it slash discord. Join all of us. Even if we're not there, you can post questions up in our team. Is there usually almost 24 seven, but there are a lot. And you can also post on our forums. You can contact customer support. There's lots of ways to connect with us. And we'll also keep you excited and hopefully inspired all throughout the week. Each week as we do our things. We're still standing. Yeah. But for now, let's do some top secret. Yeah. All right. Get it. Get out of the vault here. What's in the vault today? I don't even know. Well, you do. Because you did it. You well, you filmed it. So we have the low power thing. And then we have the Linux feather. So I'm going to play the first video. And then we'll play the Linux feather thing. Yeah. All right. All right, Ada. What is this? Hey, I'm working on gravity of my ESP32S2 feather. And you might be wondering, well, why did I have to revise this? Well, I kind of messed up the power stuff a little bit because I used I had the pull up resistors connected to the three volt line and I'm switching on and off the power. But if you look here at my PPK output, my power never really gets below about 720 microamps, which is really, really high. If you look at my oscilloscope, the voltage never gets below 1.3. So I'm getting that leakage voltage from the two, five, 10K pull-ups. They're kind of self-powering or backpowering the iSquad C bus. So with the revC, I switched it to user regulator. So when I swap out to this revCPCB with the exact same code, first thing is you see that the voltage definitely goes between three volts and ground. And on the power test, zoom in. And a whole lot of people wanted a Linux feather, so here's a little bit of a preview. This is an all-winner F1C200S. It's the big sister of the F1C100S. This is one of those kind of famous all-in-one Linux on a chip type things. It's actually got RAM built in. All it needs is some external NOR flash and maybe an SD card. And it's like a full Linux computer. It's not a very fast one, but maybe enough to run some simple Python scripts. So I thought it would be fun to design a feather, so I started the schematic capture with an SD card, micro USB host. Instead, I'm starting to lay it out where you'd have a CP2104 for the serial console. Maybe it would be battery-powered. It would last a long time on a battery, but you could run it on a battery. Micro USB host out here. And then I started to get all the other components going. And I think that micro SD card will be on the bottom. So Linux feather could be coming soon. Okay, you were saying? Sorry, I was so excited. I actually wanted to make a Linux feather for a really long time. I got these MediaTek modules a long time ago. But what I like about this is it's very inexpensive. And there's people who've used this chip. There's this Linux business card. And there's built-in support for it. So I thought it could be a good start because it's inexpensive enough that if it doesn't work out, I don't feel too bad about it. Okay. And that's top secret for the week. All right, rolling right in the questions. We have a few lined up. Yeah. It's up to you. You can answer this because top secret, we don't always answer questions about it. We used to call it. It's not out yet. Don't ask. But then we have like top secret because there's these things. But anyways, earlier today, yes, we showed off a Linux feather board and the works is going to be a two-layer board. I don't know yet. Don't know yet. Okay. Next up. Is there a resource to use to figure out the name of various connectors from pictures? I like to buy various pigtails for landscape power supplies used in holiday inflatable decorations and it's difficult to find matching connectors when the power supply fails. It's really hard. I don't really know anyway, other than just experience, there's no visual like machine learning thing so far that's been good identifying it because there's these such little details to look for. I would post it in electronics form and just say, Hey, does anyone know what this connector is? Honestly, people do that to me and I usually can like point out what it is. Sometimes they tag us and we can figure it out. I just put in my Adafruit order for my dog's new collar. Yay, is it possible and affordable to have a custom flexible surface mount PCB made? I would go inside. Corey's collar gets that name of the dog with the micro GPS and more modules and spread out for thinness. It would be neat to service mount the parts than hand wire them. It's tough because I think I don't want to recommend it because honestly, flex PCB is not meant to be flexed. It's meant to be like flexed once in a hard case. It's not meant to be actually twisted. It would crack. So even though it's annoying to wire stuff, I think if you use silicone wires, I think you'll actually be happier in the long run. Okay, good advice from my data. All right, question. You showed the ESP doing video out while a simple connection. Any plans on a breakout, something like a backpack feather wing or could the pin be manipulated to go to a quick connector or to a breakout? Yeah, that actually goes out on the DAC pin and I don't know if we would do a feather wing. It's actually quite simple. You just Google for like ESP32 and TSC output or wait till JP writes a guide. It's like literally like two resistors and an RCA jack. So not sure if we'll make a custom hardware for it, but you can pretty much free wire it. Okay, next. Is it relatively easy to upload a bootloader to the RP2040 chip? I want to design a board from scratch. I previously loaded bootloaders on a few different AVR chips. You don't have to because the bootloader is built into ROM. Weird, huh? You can't break it. You can't delete it. If you hold down the CS pin while it's powered, it will automatically enter a USB bootloader mode. Super freaky, but it does work really well and it's UF2 compatible, which is great. Yes. Next up. Will a touchscreen version of the new 1.9-inch TFT display become available? Are there touchscreens of the size, feasible, and useful? I don't know. If one comes available, I'll definitely take a look at it. I haven't seen anything yet. Okay. The redesigned USB32S2 boards are they otherwise equivalent to the prior ones, already sold except for the lower power draw and deep sleep, so no longer battery life. Yeah. For the QDPI ESP32S2, yeah, they'll have much longer battery life if you're using deep sleep mode. If you're not using deep sleep mode, then the battery life doesn't matter. Like it's only in that particular low power sleep mode that the power consumption was much higher than it should be and it's now fixed. All right. What kind of flexible connectors are used in older slider and flip founds? They really did all use flux. I mean, flux PCBs have been around for a lot longer than you think. They were making them in the 70s. They were just very expensive. So yeah, they use flux PCBs, polyamide PCBs, just like we use now. Will the feather be denoted in the catalog pages? I'm sorry. I think that means the Linux feather. Will it be? Yeah, once we have it, it'll be there. Yeah, we'll have a feather. But right now it's not there yet. It doesn't exist. I really, I just started the schematic. It's in here. It's in there. And to only get it out, you have to put pad tie in. All right. What's your preferred connector for single wires and small gauge wires, bullet, spade, along those lines? I'm actually liking the JSTSHs I'm using for quick connectors. They're very small and compact. They're one millimeter. You can't hand solder them and you can fit a lot of pins in one millimeter pitch. Okay. Do you think a guide for discontinued products could be useful? I get them when saving up and it's bye-bye. Maybe it's cheaper to build rambling. Thank you for your sharing and encouraging. So I think I will say, if I understand this question, is it good to document something? The answer is always yes. So even if you have a discontinued product or project, you should document it and get it out there. Because you never know who's going to need it later. There's a lot of good reasons to publish. Yeah. And we pretty much do not discontinue stuff if we can keep making it. The only time we discontinue is if we can't get it. Like, you cannot get a Pi Zero right now. So it's like, if that discontinues, it's just totally unavailable. Or like, you know, we had a really cute cat lamp kit and the company, like, their website's gone. Like, they just poof into thin air. And that does happen about, you know, once or twice a month. We contact a company that we buy stuff from and they don't reply to us. And there's really no warning, unfortunately. It just kind of happens. It's part of life. But, you know, anything that we manufacture in-house, as long as we can get the components, we will continue manufacturing it until we get less than, like, 10 sales a year. Okay. I've been experimenting with the 40-pin RGB TFT friend and some microcontrollers. Do you know of any experiments done with driving such displays with RP2040 or SP32? The SP30 doesn't have enough pins. The RP2040 might, I think there is probably a demo for driving, you know, TTL displays. Or if not, it could be done with PIOs. But you would have to do it in, like, three color. But, like, you wouldn't be able to drive all 16 or 24-bit color, because there's not enough pins. So you'd probably drive it, like, 9-bit color or maybe, like, 12-bit color, where you just, like, tie the low pins to ground. And it could be possible, but it doesn't have a native support. I think the ESP32 S3 might have TTL output support. You just need a hell of a lot of pins, and so it's quite rare. Okay. And then, do you think the cost, the price of OLEDs will ever come down? No, OLEDs are just expensive. They're much more expensive than TFTs. It's just they're cool-looking, but they're just more expensive. All right. So actually, sometimes you'll see, like, you know, on your, like, little cell phone hotspot, it looks like an OLED, but it's actually a TFT, like, to make it look more expensive. They have the TFT in monochrome mode. It's, like, makes no sense, but they want it to look like an OLED because, like, old-style hotspots used to use OLEDs. It's kind of freaky. And those are questions. That's questions. All right. That is our show for tonight. Thank you so much, everyone. We're getting out of here at 9 o'clock on the dot tonight. We've got a bunch of stuff to do. Thank you so much for tuning in. We very much appreciate it. Don't forget the code is WISCAT, 10% off an Adafruit store. You get free stuff, like all these things. Fill your card up with goodies. Stay tuned. More cool hardware is coming. We have a lot going on. A lot of videos coming up. A lot of new hardware. We are designing and redesigning a bunch of things. Special thanks to Jesse May, behind the scenes in the Adafruit Slack chat, and more. And I just wanted to say, send it out. Good, peaceful vibes. Hopefully, we can all come together and find ways to connect with one another. Everyone makes something. And it's been a tough couple of years. And I hope we can all get together and continue the movement towards peace and building. Yes. Yeah. So we'll see everybody next week. Thanks so much. This has been an Adafruit production. This is your moment of Xenor. Have a great week, everyone.
