 from York, it's, that's this engineer. Hey everybody, welcome to Asken Engineer. It's me, Lady Aida, with me, Mr. Lady Aida on Camera Control. It's that time of year, we're wrapping up the year, we're kind of sliding in to the end of 2021. We still got plenty of cool stuff to show you on this Asken Engineer show, next hour full of hacking, making, software engineering, coding, videoing and more. We're broadcasting here from the Aida Food Factory in downtown Manhattan. We're not wearing masks because nobody else is around. We're keeping it safe, but at this moment, we're the only two people here. Yeah, I have to do those announcements to make sure we're setting a good example, but also we like being transparent, telling everybody how we're running this thing here in New York City. All right, so why don't we kick it off, Mr. Lady Aida? Tell them what's on tonight's show. On tonight's show, the code is resurrections. And the reason why is, so as soon as we're done with the show tonight, we're gonna go and watch the matrix for resurrections. So that's the code. It'll help me remember what date it is and stuff like that. So that's the code. Temporate that off in Aida Forest or all the way up to 11.59 p.m. Cause I can stay up late tonight. Watch the matrix. At Aida Food Live Series, the shows are gonna be talking about what we do during the week here in More and Clean Show and Tell. Time travel around the world of makers, hackers, artists, engineers, news going on in the maker world, engineering world and more. Help want it. We're gonna stop by the Aida Fruit Jobs Board, jobs.adafruit.com where you can post your skills or if you're a company, hire the best people in the world cause that's where they're hanging out. At Aida Fruit site. Got some main New York City factory footage, some 3D printing, including a cool speedup video. We got INMPI brought to you by Digikeon Aida Fruit. We got a cool one this week from TDK. Got some new products. Got some top secret. We're gonna answer your questions. That's right. We do that on Discord. AidaFruit.it slash Discord. We can join all 32,000 of us. We can hang out all the time. All that and more on, you guessed it. Ask an engineer. Okay, Lady Aida. So let's do one little quick thing and then we'll get into paying the bills and more. So we do these every couple of weeks or so. The spike is back here in New York City. So back in October, we purchased a ton of rabbit tests because we're like, hey, this isn't over. There's gonna be a spike probably right before Christmas. And here we are. It's not even fun to predict a future anymore cause you're just trapped in this glass ball. So we've been able to get our team members' rapid tests while they're waiting for some of the longer line tests here in New York now cause it's back to that. So far so good. We haven't had anyone test positive. There are some people in the external circles like households of family members or friends or they go to an event and something comes up. So it shields up again. We've been wearing masks even before all of this. We decided, let's just do that anyways. All the team members are vaccinated. Everyone has paid time off for boosters and more. Also flu shots. And so that's how we've been running stuff and it's been working out for us. But I understand not every company is the same as Adafrit. So in New York, some of the things that we decided to do was we had three events we can go to. We decided to only go to one. It was our visit to her folks because out of all the things that was the only one that was important to us. So we just minimized our risk profile. And who cares? There's things that we could do later for sure but seeing friends, family, especially when it was a trip that we needed to take. We haven't taken it for a long time. That was the one when we said, well, this is how we'll spend our risk. And we have COVID tests and everything. We're all boosted. So that's what we're doing. That's what a lot of the folks at Adafrit are doing. So if you ever have any questions about how we're doing stuff, you can always email me ptadafrit. We have no problems sharing all the stuff we're doing because we're still here, still standing. Speaking of, if you want to purchase stuff that will go directly into our employees paychecks because we're about to do our profit sharing bonus for the end of the year, you can also get free stuff. Lady, what do they get for free when they're shopping on the Adafrit site? I'm glad you asked. We still have our pink feather promotion going on. If you order $99 or more, you get a free pink feather RP2040. This adorable board is just like our RP2040 feather, but it's in pink. How can you not love that? 149 or more, you get a free STEM IQT board. We have a couple of different ones in stock. Depending on whether you, if you make an account we'll make sure to send you a different one each time. Otherwise it's random and we've got sensors and controllers and accelerometers and drivers and ADCs and stuff like that. UPS Ground Shipping is free for orders of $199 or more. That's free Ground Shipping in the Consulate of the United States, $299 or more. You get a free Circuit Playground Bluefruit. We're still waiting on our Circuit Playground Express Parts to come in to finish making another batch of CPXs. But in the meantime, we'll give you a CPB instead, which has Bluetooth though energy and runs the NRF 52-840, great for wireless projects. Okay, and don't forget the holiday schedule is here. Go to Adafruit.com. It's all over the site, constantly, always, forever. Basically, it's December 22nd. Good luck getting anything anytime before Christmas. But please continue placing your orders. We'll let you know exactly when anything's gonna ship. Just make sure you know that it probably will not get there by Saturday. You could try, but probably not, and it's something that's outside our control. So we do a live series of shows. We just did show and tell. We had some Adafruit folks. We had Tim from the guy. We had Liz. We had some retro stuff and more. And then Jepler showed a project, Birdbeth, IOT, Birdbeth. And then we also discussed teapots that were rendered. So do check this out. And non-rendered. And non-rendered. And then I was talking about our idea. Sometimes I have to take the blame and or credit for some of these. I thought we could call IOT things Wicked Smart because we just got back from Boston. And instead of calling it Machine Learning or AI or Computing on the Edge or TinyML, we would just say, oh, that thing over there is Wicked Smart. What do you think? Yeah, okay. All right, well, you could tune in for all this excitement and my ideas and more on Sundays. You have great ideas. Yeah, on Sundays, we do Desk of Lady Eta. Lady Eta, we do part one and part two. What was part one of Desk of Lady Eta on? Oh, sorry, we didn't do it on Sunday. We did it on Monday. On Monday, because we were on time on Sunday. So Desk of Lady Eta, I showed off the final rev, rev C of the TFT ESP32 S2 Feather, fixed a couple of things with the power supply and showed off my power analysis test where I go into ultra low power mode, light sleep mode and normal mode. So showing that I can get down to 80 microamps of current. Okay, then we do a segment called The Great Search and this is kind of the more popular thing we do now because there is a part shortage and you showed how to find parts. What did you try to find this week? Okay, what I found this week was for the Scorpio board, I needed an eight channel three to five volt logic level shifter and I wanted one that had TTL inputs. I wanted one that was very, very small and so I showed how when I was designing the board, how I specced and located the correct logic level shifter. And hopefully I'll get the board put together and I'll make sure it works. Picking out TTL logic is a couple tips and tricks so I talked about this. Okay, and folks should stay tuned to the top secret because we have a new board announcement that we're gonna show off, Scorpio. Yes. It's a new board. Yes. Man of Fruit, okay. Yes. JP's product pick of the week on Ohioatis this week because JP is on vacation. So do tune in to JP show next week and or the week after, check your local listings as they say in the biz. But we have a little neat snippet. Gonna play these back to back. One is from JP's workshop show. This is a macro pad thing that he was working on and then I'm gonna show the latest Parsec. That's where we show some cool circuit Python based projects code and more that JP shares with the community. So I'll see you on the other side. First up JP workshop highlight and then circuit Python and Parsec. But the circuit Python Parsec, I wanted to show you how you can use pretty much any GPIO pin on your microcontroller as a ground pin. Why would you wanna do this? Well, sometimes you wanna plug things in. Like you can see here, I've got a couple of LEDs with resistors plugged in and they're on either side of a little cutie pie board. There's only one pin marked as ground on this. Point at it right there. That's the ground pin. Well, you can't share that too easily with a couple of these leads if you're going into a breadboard. Great, but sometimes you just have header pins on your board and you wanna plug things into them. What you can do in this case, if you don't wanna kinda crowd things in, is pick another available GPIO pin and set it at a low value, which essentially acts as a ground. Now, this isn't as high a current ground as the ground ground pin. So you only wanna use this for things like LEDs and buttons and switches, nothing higher current. But it works really easily and really well. So watch this. You can see here in my code, I'm setting up by importing library for board and digital IO. Then for this red LED, I'm simply setting the pin that the high side is plugged into, which in this case I'm plugging into the RX pin. So I set that to be a digital in-out pin with the direction set to output and I set the value to true. It lights it up because it's setting that pin high. So we're getting three volts out of that roughly. On this other side, what I'm gonna do is same sort of thing. I'll set up one of the pins, in this case the TX pin, for the high side of the LED, the positive side. But then to fake a ground, what I'm doing here is I've created a variable called fake ground pin. And here I'm setting up a digital pin. It's a GPIO pin A1 in this case. And I'm setting its direction to output, but then I'm keeping its value low. I'm setting the value to false. This essentially acts as a ground pin. So if I hit save now, what you can see is our green LED lights up as well, even though I didn't have to clutter things up by using a single ground pin. And so that is how you can fake a ground pin on your microcontroller inside of circuit Python. And this has been your circuit Python parsec. Okay, on Friday, there's not gonna be a deep dive with Scott. However, Fummy Guy Tim is going to be taking over that slot for this Friday and possibly next Friday. So stay tuned to our Twitter's, to our YouTube, to our Twitch, to our LinkedIn, to our Facebook, our Meta. And let's see what else. I think it's live on Twitter as well. Probably a couple of places, but do check that out. Time travel. Let's look around and we're all makers, hackers, artists, engineers, news that's going on and stuff that we have to deal with on a regular basis that, you know, I just gotta deal with sometimes. So as a service to the entire community out there on Adafruit.com slash NFT, by the way, we don't do NFTs. These are, it's a gallery of nice friendly t-shirts. We have text for those of you who do things like public speaking or those of you who do live streams or those of you who have to sign photo releases for all sorts of stuff. And the reason why we have this text up there is because there's lots of times where someone will take your photo or have you in a video and then all of a sudden you wake up and now you're in NFT. And we knew this was coming and for years, even before there was such thing as NFT or it wasn't even called NFTs, we always make sure that we had our intellectual property lawyers look at anything that our Lady Aida or me or a team has to sign. And so basically we put the text up. So Adafruit.com slash NFT scroll down to the bottom past the amazing t-shirts that our team has that they collect and take a look. The short version or I'll just read it. Speaker specifically reserves her rights of publicity and privacy and expressly prohibits the use of her name, image and likeness apart from use in the live session and works created promote the live session videographer, photographer, streamer, may not license the content for recent advertising or marketing of a unrelated party's products and services without prior written consent. So basically it's just like, hey, just talk to us before you do something. And no matter what we do, so we got blamed for, I'll get to that in a second. I got blamed for Radio Shack. We didn't buy Radio Shack. I get blamed for everything because why not women online blame her? Super fun. Yeah, super fun. And that's what a lot of dudes are doing. So anyways, we have this and instead of just being mean and crummy and trying to dunk on people, we're trying to do a helpful thing, which is this is text that we use. It's not legal advice, but it's text we use this will probably save you later. So I've been reaching out to some of the folks who are a little surprised to find themselves for sale for ETH and so far so good. It's been working out. Next up, this is from Q. Q's in Texas. She just moved from New York to Texas and she sent me this thing. She just wants to say Merry Christmas and Happy New Year. Adafruit, this quality is this friend of mine. So I just wanted to put this on her. I said, hey, can I put this on our show? And she said, yeah. Next up, adafruit.com forward slash cats of engineering and now has an RSS feed. Yes. Because that's what we do. Really excited about that. If you need help with that, you can email me ptadafruit.com. This is a screenshot of my newsreader for my Mac that I happen to like, which is NetNewsWire. Reminder, we did not buy Radio Shack. We have nothing to do with RadioShack.com. Please stop blaming us online for anything to do with Radio Shack. We have nothing to do with it. We interview the new owners of Radio Shack every couple of years because there's always new owners of Radio Shack every couple of years. This is my sign. From this sign that we bought off the side of a Radio Shack that got scrapped because Radio Shack went out of business a few years ago and it says, heck, and that's the back of my desk. So anyways, nothing to do with it. Cool sign. Didn't buy them. Stop blaming us. Y'all are jerks. You're mean guys online. Stop it. Move on. Okay. This is from 1999, Lady. We're gonna get this running. This is your, you have a text adventure that you made. For 6.001. For your MIT. It was the final project for freshman computer science class. I wrote a text adventure, which was the assignment was to write a text adventure. Little did they know that I'd always wanted to write a text adventure. So I went all out and I wrote in text adventure and we're gonna post the files up but they're in MIT scheme, which turns out that. You have to figure out how to get that running. We have to get that running and you think, well, why don't you just run an MIT scheme that's available from glue? Turns out whatever changes they made to Athena's scheme is slightly different. We're getting there. We got it to load and now we have to kind of, there's some things about like whether a list is empty when it's empty or it doesn't exist. I don't know. I think it's cool that this is like Lady at Archeology. We're all be able to. Some of the oldest code I've written. Really? I mean, I think I could dig up some older code. But this is, you know, I unfortunately lost a hard drive that had a lot of, I mean, before Dropbox, you know, it's like when you lost a hard drive, you really did lose everything. But very early code, but it's actually a funny game. Yeah. I'm going to upload it to archive.arch. I've not had luck with archive that are recently putting stuff on there, but we'll see. I will keep trying. Next up. So AdaBox, one year of AdaBox is possible for you to get. We have less than 50 slots open. I get an email notification. Don't forget it is AdaBox edition. So that means the holiday edition, which we would normally try to get out by, you know, Christmas is going to be shipping during a season. This season happens to be winter. This will be out January, February. Please, please, please get it out. There's going to be none left. It's the closest thing to like back orders that we have. It'll be for a new product. It'll be really cool. And I think it's going to be one of our best ones yet. AdaBox.com. Okay. Help Wanted. We are putting everybody back to work in this country. We're trying. Help Wanted, jobs.adafruit.com. There are three jobs on the Jobs Ward. There is an audio circuit. There's remote instructor for summer engineering program. That's with Bluestamp engineering. There is open source circuit pipeline driver for NFC chip. Must include point to two point communications. And another remote instructor position, which is for a summer engineering program. Do check this out jobs.adafruit.com. We moderate all of them. We look at all of them. We make sure they're not scammy or sketchy or whatever's. And so do check it out or post your skills. If you're looking to make some more coin. And I mean, that is a physical money thing, not the other stuff. Okay. Let's do some Python on hardware news, lady. Mm-hmm. Okay. This week, I'm going to talk about the podcasts that the team did with Tom's hardware soon. I thought this was kind of cool. This is a retro RPN calculator emulator using the PyPortal Titanium with Circuit Python. And the user interface is mostly done. You're going to be able to see it later in action. But I like people build in their own calculators. It's kind of like gradient backgrounds, Q. Yeah. It's the steps of building all of your own equipment. Topping your tree with a glowing, can you say this word? No. Rambi. Because he did a Dickey Heed one. Yeah. Anyways, Powered by Circuit Python. Okay. We have some guides on upgrading to the latest version of Raspberry Pi Buster. Sorry, from Buster to Bullseye. We have some LEGO plates that we've posted. We have a call for Moo translations. Do check that also. Also, breaking news. There's a new version of Moo. It's available for code with .moo. Next week, the guest editor, I'm back. The restraining order is over. No, I'm back. I'm back to doing the newsletter. Originally, it was here. No, Ann's been doing it. Yeah, Ann's been doing a great job. I promise you it's going to. So if you all know me, I did Hackaday, and I did Engadget, and I did magazine, a lot of online offering. And if you like black and white photos, if you like that style, if you like lowercase, if you like things a little edgy, a little artsy, a little gothy, you might like this newsletter that I'm doing. Yeah, the gothiest, the edgiest, the lowercase-iest. Yeah. And if you want a preview of some of the stuff, you can go to my personal Twitter, twitter.com, forward slash peterone. And you can look at drawings or photos. Parrots. And you can say mean things to me and dunk on me. Or you can enjoy the art. Or you can enjoy the art. Look at birds. And look at birds and some medical tests and stuff like that's kind of fun. I got some x-rays. Everything's fine. So next up, what I did want to show and talk about is keyboard. Wink, wink. Yeah, tick, tick, tick, tick. So keyboard is what we're calling a whole series of keyboard-based products from Adafruit. So we have a KB2040 and it's the pro-micro form factor. And the kind folks at Tom's Hardware had Dan and Jeff and Scott on the show that they do. So Lady Aida, what's the big deal about this pro-micro keyboard thing? Well, the RP2040. Why is it a pig? Because it's a key, but we don't want to call it a key because a lot of people can say key. So we want to call it a keyboard, which is a little pig with a key as its nose. The KB2040 is an RP2040-based board. So it's using this extremely fast, very powerful chip from the Raspberry Pi Foundation, their first microcontroller. And we put it into a pro-micro form factor with 20 GPIO pins. We break out D plus and D minus as well. So you can also use it for advanced USB configurations. And the idea here is that you can use this design and existing macro pads and keyboards and upgrade it to use circuit Python or micro Python or Arduino. And it's a big upgrade from the 32U4 that a lot of people use for keyboards. It runs out of memory very easily. The 32U4 really only has 2K of RAM, 32K of flash, whereas this chip has eight megabytes of flash and 256 or 264K of RAM. So a ton of memory and it's very fast, like 133 megahertz dual core. Right now there isn't QMK support, but I think it's coming. I think people are working on QMK support because so many people are building RP2040-based boards. And also, catch the whole thing. I can dence this down to like 20 seconds, but it's about 30 minutes long and the entire crew is there and you'll be able to learn all about this and then more, it's a deep dive, as they say in the biz. Oh, it's also a dollar less. I wanted to make the QMK 2040 cheaper than the micro, the pro micro, but it has all the stuff you want, USB-C and. And then I say our big news for the week in the world of circuit Python and more is Pileap app is available in the App Store. Congratulations Trevor and Antonia and Scott and Kenny and Marcos and everyone who's been working on this. We have a guide, we have a blog post. It's in the App Store and I'll get to one little note in a second. When you go, you can open it up, you could see all of the screenshots, you can get the description and more. Will we have an Android version? Yes, don't be mean about it. Every single time we have an Android version and then only two people download the Android version of something, but leading all the way up until that, they're just mean. So stop doing that. It doesn't help the other Android users. So anyways, we're doing this one first. Expect an Android version down the road, but we also have other ways to get things on Bluetooth hardware. You also use it where you can use. From Android. From web browser. Yeah, from all sorts of things. So we're going to make sure you're able to do everything all the time, everywhere from multiple devices. That's kind of our jam, but there's this weird thing that comes up every single time. No matter what app we do, we released an Android version and someone said, do you have an Android version? I'm just like, are you kidding me? It's an Android version. And they're like, oh yeah, sorry. I'm just used to asking that. Please don't do that. So that's everything in the world of Python on hardware. We deliver these to your inbox every single week. Get the newsletter that I'm going to be writing very soon. You can go to AdafruitDaily.com. Search around. We're the only site that I know of at this point that respects, do not track. It's a separate website for newsletters. You can't get spam from us. You can try, but we're just not going to do it. And you go to AdafruitDaily, not Adafruit.com to get any of our newsletters. We wanted something completely separate so no one could ever say, y'all are spamming me. We just don't have those pop-ups, don't do anything. Let's Python on hardware news this week. That's what we're doing. Okay, lady, we're an open source hardware company. I think Ann posted this up or is posting it up. It is the impact of open source software and hardware on the technological independence, dependiveness and innovation in the EU economy. Check it out. It's a PDF, you can download it, you can share it, you can read the summary and more. Don't know if they're doing one for the US yet, but this is EU, so do check it out and you can see what's going on with open source hardware and software and its impact in the EU. Speaking of, we have 2,601 guides. That's how I know we're an open source hardware company because we've got all these guides and code and stuff like that. Lady Eda, what is on the big board this week? Okay, we've got that guide for these, you saw a little video from JP on making an interface for doing color correction on images. So he showed how to plug together various STEMI QT boards to make a no solder control panel. We've also got a guide on, can you make the... Do you want? Well, I can't read the text. You want a bigger? Yeah, can you read that? The RGB matrix circuit Python guide, Jepler updated it. I think he added the RP2040 feather and RP, sorry, the RGB matrix feather wing to show how to use it. Or maybe it was the ESP32 S2 Metro with the shield, I don't remember, but we had another page. We've also got a guide on the Piley Bap. We do. We also have... Kenny started out the guide for the QT-Pi ESP32 S2. There's more to come. Kenny's on vacation, but we got some files up just because people are always asking for schematics and pinouts and files, so that's up there. Carter did a guide on making a DIY USB trinket that requires no soldering to make a DIY air quality monitor with humidity, temperature, biometric pressure and CO2. And then TAC wrote a quick guide on taking our NR52840 boards, whether that's a feather or a dongle, and turning it into a BLE sniffer. And you can install the firmware with UF2, which is super awesome, because you don't need to use a J-Tag or J-Link, J-Tag interface to load the firmware. You can just drag and drop it. There's a couple extra steps because the soft device needs to be updated as well, but he has written everything up for you. So if you have an old blue fruit feather and you wanna turn it into a sniffer, here's a tutorial on how to do that. Okay. And it wouldn't be a celebration of open source hardware without the place that makes it. Here, Adafruit, let's look at some factory footage. Hey, Dana. Yes. And it wouldn't be a main New York City factory footage without a time lapse from the Disney headquarters that it's gone from large to loud. That's its thing now. Initially it was just large, and now it's very loud. And then one other note, because I have to fill up our show with things so I can send links to people later. So we don't have hand models. Any hands that you see in any of our photos, it's people who work at Adafruit. Some of them have cool tattoos and scars and nails and all sorts of stuff. These are real people who really work here. Stop saying we have actors and hand models and no one really exists and birds aren't real and stuff like that. Okay, three printing. You want to do these back to back later, Dana? Yeah, let's do them back to back. Okay, we're going to do these back to back. We've got the cool project that Pedro did this week, and then we're going to do the speed up of the most recommended mask to wear now that'll keep you safe from everybody else. From variants and people who may have variants. Yes, so stay tuned for part one, which is the project, and then part two is the mask that everyone should print out and give it to their family and friends this holiday season. Hey, what's up, folks? In this project, we're making a visual light display with Neopixels. We designed a lamp with edgelet acrylic and added Neopixel LEDs. It looks like a frame by frame stop motion when each pixel is lit up one at a time. We thought it'd be fun to engrave some festive designs in different shapes. The acrylic panels are swappable so you can use this to make all sorts of creative animations. For this project, we have it powered by the Cutie Pie RP2040 running Circuit Python. It uses just a single strip of Neopixel LEDs with a total of eight quarter inch thick acrylic panels. We engrave some snowflakes and letters, but you can do all sorts of fun arts and graphics. For any Neopixel project, we like to use Circuit Python because it's easy to use the LED animation library. We strung together a few chase animations using the animation group module with each one having a different color. We set the timing to a quarter of a second so each panel has a little bit more time to be seen. The LED animation library makes trying out different settings really fast and easy. The LED strip is fitted into a 3D-printed holder with each LED fitting into a little cavity. Our 3D-printed holder keeps the LEDs isolated so the light doesn't leak into each other. The acrylic pieces feature tabs that are press-fitted into slots that are on a separate holder. They're placed directly over the LEDs so they're nicely edge lit. The parts are made with PLA filament and they can be printed without any support material. All you need to build this project is a strip of Neopixel LEDs in the QtiePie RP2040. The bottom cover features a built-in holder for the QtiePie and has special edges that snap-fit into the 3D-printed case. Each piece of quarter-inch thick acrylic features a 20-millimeter tab for slotting into the 3D-printed holder. The assembly is modular with the parts snap-fitting together. I designed the holders for the LED strip and acrylic to be parametrically driven. This means updating the pixel count will add or remove slots from the design so it's easily scalable. The CAD files are free to download. Links are in the description. We hope this inspires you to check out the QtiePie RP2040 in CircuitPython for your next light-up project. From everyone at Adafruit Industries, happy holidays and happy New Year. Don't forget on Wednesdays, learn how to make all this stuff and more. No Pedro. Okay, lady. It's almost time for, you guessed it. I NMPI, but first up, the code is Resurrections because it's matrix four tonight. That's why I'm gonna watch right after this. All right, let's do this. Ready? Yep. I NMPI. I NMPI, I brought you by DigiKey and Adafruit. Thank you, DigiKey. Every single week we show the latest, the greatest, the I on new product introductions this week. It's from TDK, lady. What is this week's NMPI? Okay, this week's I NMPI, like we mentioned, it's from TDK. We had them for their little sensor bugs so they're coming back. Do have one of the coolest logos. We see it in Times Square. The TDK sign is pretty sweet. This is, I wanted to make sure I get the part number right. The BCS4430B6, this is a series of ultra-thin, ultra-flexible solar cells for use with indoor electronics to power your IoT, your portable or wearable electronics, using- I look at the smart stuff. From lights inside building. So just what it looks like, these are amorphous cells and this one is I think like 44 millimeters by 30 millimeters, that's the name. And it's got six cells. You can even see all six cells one by one in this picture. And then it's super flexible and I'll show it on the overhead. Maybe I'll do that now before I get into it. Let's do it now. Okay, so this is the solar cell. So it's amorphous, so it's ultra-flexible and it's incredibly thin, it's 0.2 millimeters. It's basically a thin piece of paper and it feels about as thin as a thin piece of plastic or paper and on the back are these two points that you can connect to to make electrical contact. And even indoors, just with the fluorescent lights here, you can see it's lighting up this LED quite nicely. So this is extremely, extremely skinny and extremely flexible paper-like solar cell and it can be easily bonded or soldered into your project to give yourself some power, even from indoors. I mean, of course it'll work great outdoors but it's designed even to work with indoor lighting which is not that bright, to be honest. So this is the VCS series. They can make them in custom sizes and shapes but the goal of this one is just to make ultra-thin, ultra-light, one of the suggested use cases is like a credit card type thing, something so thin that could go into a wallet or it goes into a wearable, something that has to move around a lot so you can't use a fixed monocrystalline cell. This one will give you about 4.2 volts open circuits around 2.6 volts running circuit and operating current about 30 microamps of current. So yes, these are very, very small and thin. They don't give you a lot of current but depending on your circuit, you might be able to either charge up a super cap or use a buck-boost converter or whatever to convert that ultra-low amount of current into something usable. You can get these in custom sizes, even a circular size, customizable number of cells. So for your product, if you need a lot and you don't want to cut it down to size, of course you can cut this with scissors but let's say you're like, I want to come with a particular size, you can get them customized. And so what this reminded me of was when you had a solar calculator and I had one of these and they were great, I actually prefered it to the battery one because the battery would always die but with the solar one, you sometimes have to hold it up to light for a few seconds to kind of get the internal capacitor charged but I found that they worked quite well and that's the same idea here is that this is for ultra-low power electronics. It's gonna have to be designed to use a solar panel but of all the energy harvesting techniques that I've heard of, like piezoelectric or thermal, solar is kind of the most inexpensive, reliable and well understood. People who are always like, oh, I want to charge something based off of the motion of a person. It's like that's actually really hard to do and piezoelectric usually you have to press a lot harder than you think. Like it's not very comfortable with a solar. You know, it's trickle charging but there's always gonna be light around. So if you can work within the constraints of the low current, you're good to go. People who've never used solar panels, they're kind of weird because they're diodes running in reverse basically instead of an IV curve going the opposite way they go the positive way because there's positive power going out not going in and the operating curve does change with light levels. So this is a diagram from a linear tech MPPT controller and it's not for this panel but you can see the green line as you get more sunlight or ambient light you see the curve gets taller and taller and taller the how much current you can get out and then the blue line is the max power and so you notice that there was kind of a sweet spot called the max power point which is kind of at the tip of the curve just as it starts to sink down. So using a solar panel you can't just treat it as a voltage source or current source is kind of in the middle. You want to, it'll give you a voltage but as you draw more and more current the voltage will start to collapse. So what you wanna do is use just enough current that the voltage has started to collapse a little bit that'll give you the max power and so one thing to say is if you're gonna use these little solar cells you do have to design your circuitry and your power supply to take advantage of this and use it intelligently. This is the curbs for this particular panel you can see the different illumination levels based on lux and the voltage and current you can get and get out. One thing you can do is one just design your circuit to use under 30 microamps of current depending on what your circuit is like as a calculator you can design an ASIC to use less than that much power. Second thing is you can have it trickle charge a super cap or a primary or sorry secondary battery or a chargeable battery. It slowly, slowly trickle charges the battery capacitor when it gets to a certain voltage it turns on your circuit and then it runs that can be good for IoT where you know a little sensor or something lives in a room it only has to send the temperature or humidity data every 10, 15 minutes. So it slowly, slowly charges you know 30 microamps at a time charges up the super cap super cap gets to three volts or 3.5 volts whatever the circuit turns on depletes the capacitor while it's submitting that data or sending that data over a radio and then turns back off. Third option is to use something like this it's like a specialized chip it's gonna cost a little bit more but this is designed specifically for energy harvesting and is designed to use these ultra small ultra thin solar panels. You can't just use an everyday lipoly charger chip it has to be something that knows how to deal with again this IV curve where the max power point is as the voltage start to collapse and usually you set the max current or the max you know the cutoff voltage using resistors or capacitors on these chips and then they can charge up a battery for you or a super cap for you and they'll do it in a way that's a lot more efficient than just a plain trickle charger. Okay and in stock and good news there's 32 of these in stock and they're available on Digikey here's a short URL. Sorry there you go. And then the programmer. But very neat I do see I will say people who want to use who want to do IOT projects they want to make smart rooms solar panels really you know as long as you have the power supply designed for it they last decades they're very reliable they are you know they just work off of whatever light they've got just be aware that they'll give you a lot less current than you think whatever amount of current you think you're gonna get it's about a tenth of that but as long as you can work with that you're good to go. You sound like an advocate for big sun. I am. The lobbyist. The bigger sun. Big solar. Big lux. Okay so that's IONMPI I'm gonna do a couple of questions immediately afterwards then we're gonna go into new product cause there's a couple of questions that have something to do with this so we'll see you on the other side of this and that is this week's IONMPI. IONMPI. Okay I'm gonna add these questions real quick and then we're gonna do a new product so would you be able to recharge a small lipo with a solar cell like that and then how it would work with a tree ornament? You let the tree light to charge the ornament. I think that would work. Tree lights are really really dim you really want to have ambient lighting because it has to hit the whole front of the panel but yes you can just triple charge a small lipo. I think on a tree because a lot of people have it in front of a window. Yeah the window would be a good and then you charge up the things all throughout the day. Good option. That'd be kind of cool. Okay so let's remind everyone. Resurrections it's good cause we're gonna watch the matrix. Tonight let's do new products lady. Okay. Sing your song. It's time for new. It's time for new. New, new, new, new, new, new, new, new. Okay first up I'm gonna do my little bit which is go to Adafruit.com slash gift certificates cause it's probably too late to get that gift. Get a gift certificate it works. They never expire. We don't do anything weird. We don't harvest the email. We don't spam the person getting it. You can print out. We have like a print out that you can do. Get a gift certificate from Adafruit. It's great. Adafruit.com slash gift certificates. You really sell it there. Well it is. It is. It's just like what should I do? And a lot of people are like what do I get someone who likes electronic stuff? Like get them a gift certificate from Adafruit. Yeah. Let's kick off the new products with this. Okay we've got a felt carrying case. So this is I think designed for either a book or a keyboard. But you know what it fits really well? The Raspberry Pi 400. If you have a Pi 400 you know you want to keep it safe while you're moving it to and from school or a workshop. We have a zipper case but this felt case was inexpensive and works very well. It has a little a flexi strap piece and some nice felt that is you know it's not waterproof but it's water resistant. It's a nice case. It's nice and padded. It will keep your keyboard or your Raspberry Pi 400 nice and safe. Next up. We've got another Molex power cable pair. So you get a socket and a plug and they plug together. And I think all together it's 20 centimeters, 10 centimeters each. This one has eight connectors. And you know they just match up. You have you know right on one side and on the other pink, pink, yellow, yellow. Great whenever you have something that needs you know a little bit of current, a little bit of power and you want nice free hanging connectivity. I like these super fine pitches. 1.25 millimeter pitch. Yeah, these are nice. Okay and then next up we have a tour of boards that are somewhat related to each other. Sort of kinda first up. They're all similar but they're not the same. So this is the ESP32 S3 dev board with eight megabytes of flash. And I can't remember how much PS RAM. Take the part of page. I think eight, sorry, eight megabytes of flash, eight megabytes of PS RAM. So this is the most you can get with the S3. You get two USB ports, one native, one reprogramming, plugs into your breadboard or whatnot. And it's just a very powerful S3 board. The S3 is very new. So just be aware of that. It's, we're adding circuit path on support. I think Arduino support isn't there as of this video but it might come in over the next few weeks. So that's the S3, it's the biggest dev board. Now this is a C3 dev board. The ESP32 C3 is a risk five chip and so it has a lot fewer pins. I will warn you about that. This does have eight megabytes of flash. No PS RAM. The C3 does have Arduino support and ESP IDF. I don't know that it's supported in circuit Python. I don't think it's supported in micro Python either. We're not really planning on adding circuit Python support but there is Arduino support and it's risk five. If you want to play with risk five, this is kind of a great way to do so because you get like Wi-Fi and Bluetooth with it. It's got the little USB serial uploading and debugging port and you get a couple GPIO pins. Again, not a lot of GPIO pins but nothing you can start experimenting and of course it's got wireless as well. All right, and then this is a giant T-shirt sized one that you actually wear. It looks like a T-shirt but this is the ESP32 Warroom DA. The DA stands for dual antenna. So this is an ESP32 Warroom. So it's the, not the S2, it doesn't have native USB. It's like this classic ESP32 but it has two antennas and it has the antenna selector built in already so what it's designed for is to always get good antenna performance even if your normal PCB antenna isn't aligned with the source because one antenna, if the signal happens to be perpendicular to it you're gonna get very low signal strength but if you have two antennas, you'll be perpendicular to one, you're gonna be right in line with the other. So you're gonna get really good signal strength. You're gonna have a much better time and it's basically for free. You just have two antennas and it'll select her. So it's a very inexpensive way to double the chances of having a good signal strength for your ESP32. It does have this funky shape though. So just you'll watch out that your PCB layout will work with this design but I think the antenna switchover is probably done transparently for you so you can just treat it like an ESP32 and get better signal strength for free. Okay, and then the star of the show tonight so I do lay data, our team, our community, our customers and everyone hanging out is brr brr brr brr brr brr. Yes, it's finally here, another QT pie, the third in our QT pie family, the ESP32 S2 QT pie which brings some, so much expressive this week. This is ESP32 S2 which is a single core Tensilika Wi-Fi processor. It's a lot like the ESP32 but it doesn't need a USB serial converter chip which means we can make it so small that it fits in something that's like small in the corner. This is the tiniest board ever. It's so small. So there's an ESP32 S2, there's a USB type C connector for uploading and powering. There's a stomach QT port so you can plug and play add I2C sensors. It's got 13 GPIO total, 11 on pads and... It's so small we have to force the overhead to refocus. I know. The overhead is shocked. Okay. How is this so small? It's so small. So you've got analog, I think almost every one of these pins has analog but there's like four dedicated analog here. Two pins are labeled for I2C. There's a second I2C port on the stomach QT so you've got like another two pins. Hardware UART, hardware SPI pins on the high speed SPI port which means that these three pins cannot do analog. They're the only three pins that don't because the high speed SPI is worth it. It's amazing. It's like some ridiculous megahertz, like 60 or 80 megahertz. So to connect to TFTs or some devices, very, very high speed. You've got the boot button and the reset button. The boot button can also be used as a user button. There's a regulator, there's a little neopixel right here that glows rainbow or whatever you can use it for signaling. There's a ceramic antenna on the top. And on the bottom, you've got the ESP32 S2 chip with the crystals and passes a lot of 0402s. The antenna goes out here and here is two more pads for battery input and this is diode protected so you can have, you know that we're using the seed shell pinout and they kind of decided that the five volt line was output not input and so you'd have to diode and whatever but basically if you want to connect a battery up, you can connect to these two pads and they're diode protected so when you plug in USB, you're not gonna damage the USB or the battery from that. And it's got cast-layed pads and it's super small and you can use it with Arduino or circuit Python. It's got four megabytes of flash and two megabytes of PS RAM. So I was waiting to release this until I could get the chips that had the PS RAM because that two megabytes of PS RAM is so handy. And it's Wi-Fi, this is amazing. So tiny. And it's Wi-Fi. And it's in stock now. I even put in a little bit right before the show to make sure we had some. So pick some up. And that's a, that's a problem. Okay, let's do a couple of questions as we do the top secret. So go over to discordatifruit.it slash discord. We'll get to those. We're gonna do some top secret in a sec. So Lady Aida, the questions that happened during the chat. So for the CP-2102, the C3 doesn't have USB natively. That's why circuit Python is a ways off. We have a version, we have things that we're working on. I think it does have some, it says it has built-in USB, but it's not native USB. It's got like a built-in JTAG or something. So yeah, we're not really planning on supporting the C3. Our next chip is probably the S3. Okay, next up, let's click the form factor. Does the BME280 run hot on the ESP32 S2 Feather? The HT20 on the Funhouse tends to run five degrees. Celsius higher than the off-board temperature sensor. So anytime you have any sensor on a board it's gonna heat up. However, if you look at the ESP32 S2 Feather tutorial we show how you can turn on the board from deep sleep, read the sensor, send data online and then turn off the board for a couple of minutes so that you never get an ambient temperature increase. Okay, we're gonna do one more question and then we're gonna do top secret. QDPi ESP32 S2 design questions. Learn guys says up to six volts can you use four AA or triple A batteries or stick three batteries since new batteries output a little over 1.6 volts each. That's right. If your voltage, your new fresh batteries are over 1.5 volts. You just wanna make sure that the total number is under six. Oh, I'll answer this one. Adaford, will you please have a happy as holiday season as possible? Yes. Yes, sure. We're doing really good. I mean, you know, we're pieced together and skidding across the finish line and all scars but who wants to arrive at the destination perfectly pristine? I like my cracks and scars. Okay, let's do some top secret. Okay, lady, at first up I'm gonna show a picture and then we're gonna do three videos and then you're gonna show something. So first up, we saw Liz. Yay, it's Liz. On disclose location somewhere, but we did, we saw Liz. But you can tell if there's a new carpet. So you'll see Liz somewhere and we're all masked up. You can tell. That guy wasn't in the background. Yeah. And then I'm gonna show three videos back to back to back of some upcoming stuff. And then you're gonna show the Scorpio boards to stick around folks. All right, lady, what is this? Hey, this is how we're gonna test the QDPI ESP32 S2s. I'm using a Raspberry Pi to do the test and that's because I can run ESP tool really easily over USB to program using the built-in DFU bootloader. Gonna use a GPIO pin to toggle the boot and reset lines to do that. And ESP tool compresses the firmware. So it's really the fastest way to upload a bunch of code to ESP32. And then I run a self test and one thing that I do because it's got an antenna is I have an access point created on the ESP32 S2 QDPI. And on the Raspberry Pi, I do a WPA CLI scan and I look for the access point and then check the signal. My hand's in the way, so it's 50, but usually it's about 40. So that means the antenna got started on correctly and this has passed test. All right, lady, what is this? Okay, so I'm just about to get ready to release the ESP32 S2 TFT feather. I actually ordered PCBs and then realized that I was not depowering the iSquad C pull-ups to peripherals which meant they were getting back powered which changed the low power draw. So now I'm really testing the heck out of it. I got this big chunky PM2.5 sensor connected to iSquad C. You can also see I'm testing turning the backlight on every second. And here's my power graph. So you can see the big power spike when that PM25 sensor turns on. And then this is low sleep mode which is about one milliamp and then deep sleep mode. Let's zoom all the way in. It's about 80 microamps which is as low as you're gonna get. That actually is the lowest powered deep sleep mode that you can get on the ESP32 S2. So this is ready to order. Be in the store soon. What lady, what is this? Hey, there's a lot of stuff going on my desk right now. First up, I've got this MCP 23017 breakout and I got my tester PCB. I have a new thing now where when I order my PCBs from JLCPCB, I get the prototype for the panel and I also get the tester PCB at the same time. So that way I put it together and then I just put some code that it's really fast but it actually tests like every PAN and GPIO and the iSquad C address and it beeps when it tests. And then I'm also checking out some samples of pink PCB. So we got our first batch of pink PCBs from PCBWay but our standard PCB house can also make pink PCBs. So they sent us some Pantone chip like samples. These are actually PCB but with the color. So going forward, we'll have two possible suppliers for these beautiful pink PCBs. Don't forget, free with your order, $99 or more. Okay, and then you have a new board that we're coming out with Scorpio. Yeah, it's the RP2040 Scorpio. You came up with this name. It's an amazing name. So this is, it's an amazing board. It's an RP2040 feather with eight GPIO that are buffered outputs to give five volt logic levels. So this would be really good for driving many addressable LEDs. It's also got iSquared C port and a NeoPixel and some cool graphics and eight megabytes of flash here. But with the PIO peripheral on the RP2040, it's really good at driving addressable LEDs very, very fast and using DMA and not requiring any weird timer stuff. You can just set it and forget it. It's very, very cool. So this is a board specifically designed to make that easy to do. And that's top secret. You can choose to answer this question if you wish. So is there gonna be a stem connector on this board? Yes, there's one. Is it gonna be vertical? Yeah, there's one right here. You can see on the guide. It's gonna be vertical, it'll be like a stinger. Yeah, I mean, I guess it could look like a little scorpion thing. You can check it, it's hard to see here because it's so shiny, but check out the blog post. All right, I'll answer this question from the other chat. Oh, should I, no, I should do this. I should be like, hey, look, we're doing questions in Discord. Oh yeah, we're doing questions in Discord. We're doing questions in Discord. Hey, we're doing questions in Discord. We're doing questions in Discord. We're doing questions in Discord. General 32,000, that's good to hear. We're doing questions in Discord. So this one, I'm gonna break my rule a little bit because I see this in the other chat. AmateurRedo, hey, I'm operator. Would like to learn more about the maker space. This may be a tough question, however. Where do I start? Is there a good starter kit? How about RPI? So I would not start with Raspberry Pi. I would start with something like the Circuit Playground Express or something that is Arduino compatible. Circuit Playground Express does it all. So I would start with that because that'll get you into like, oh, I wanna do a bunch of projects really fast where I think when you're coming from ham radio world, it's more like, here's a bunch of protocols first. And the projects in the maker world, take a look at learn.atafruit.com. There's over 2600, hey, kinda ham radio sounding. 2600 guides, check those out. And then later on I would say, as you get more advanced, there's a collision course with a lot of the ham radio stuff, a lot of Raspberry Pi stuff, a lot of Arduino circuit Python related stuff. There's lower radio stuff, but that's what I would do. I'd start with that. Okay, everybody likes pink. Great. Everyone likes pink. Yay. Have we ever thought of doing tutorial videos for YouTube? Yeah, check it out. We have lots of tutorial videos on YouTube. YouTube.com. Ford slash Adafruit. So many shows. We have tons. Are YouTube does not promote and spotlight women's STEM companies? It's like a fact. So, because we've asked and they're just like, well, if you did like make up tutorials, so sometimes it's hard to find our stuff. You'll find plenty of like lizard creatures and birds aren't real stuff, but it's harder to find STEM stuff. It just is. And I hope they continue to work on that. I know there's some good people working on it. I hope they continue to do that. Okay, next, BA for Buffered Outputs and PIO. Question, it's so neat that you show boards. You make the test new upcoming products. Can you share how long in general those takes to code and hardware design? It depends on the difficulty, but the good news is that I build on existing ones. So it usually takes me two or three days on some of the more tougher testers. A lot of times it's trying to figure out how to test what I'm trying to test. Then easy break up board like that MCP 23017. Designing the tester took like an hour and then I order the PCB right after I order the panel. And then, because I kind of know how to test it, it's pretty straightforward because I just test the GPIO. And then wearing the code for it also takes, you know, maybe two hours. Yeah, and then, you know, one of the things that someone mentioned just to get back to the previous question, for the person asking about like, you're coming from a hammering background. So if you start with a pie, there is like an OS, there is like a ton of stuff you have to do before you even get started. Where if you pick up a little bit of Python and you do things, the REPL and you do things in like circuit Python, you're instantly doing stuff immediately and you're seeing what you're doing and you're not compiling, you're not waiting, you're not downloading, you're doing everything in an instant. So that might give you that like special five minute like, oh my gosh, I got something done, I wanna keep doing more. Okay. Yeah, Blooper version is a good one to try too. Okay. And I think, I think, I think, I think, Gladiator, I think that is, I think that's it. Okay. That's wonderful. Okay. That's our show. Thanks everybody. Okay, thanks everybody. We will see you next week, special thanks to Jesse May behind the scenes. So he's doing a bunch of stuff in our chat. Oh, we'll do one more. Any plans for a new power boost? 2000 C with more amp output for new pixel projects? That's harder than you think because there's not a lot of batteries that will give you the current you need. So it's not an easy problem to solve. It isn't just like get a bigger chip. There's a lot of underlying issues that come up with that. Okay. And again, special thanks to all of our team, the community, everyone who's purchasing stuff. When you purchase stuff tonight, for sure, it's going into our bonus and profit sharing account because that's how we do stuff here. Do check Adafruit.com slash free. We still have some pink boards.
