 Live from New York, it's Passus Engineering. Hey everybody and welcome to Ask Engineer. It's me Lady Ada, the engineer with me, Mr. Lady Ada on camera control, emotional support and overall good guy. Have a good time together. Emotional support co-host. Yes, emotional support co-host. We're broadcasting live from the Ada Fruit factory here in downtown Manhattan. That's what you see behind us. This is the Wonderland, the Candyland, Willy Wonka's factory, whatever you want to call it, where we do all the electronic manufacturing, kidding, testing, shipping, videoing, sterilizing, coding and photoing and more. We've got an exciting show for you today, an hour of all the news and goodies and updates and more from the Maker Engineer hacking community. Yeah, let's see if we want to kick it right off and see what are we up to. On tonight's show. Best hour of the week for us. The code is notable. We'll talk about why the code is notable a little bit later, but the code is notable, 10% off in the Ada Fruit store, all the way up to 11.59 PM for anything that's in stock. I'll leave it up till midnight tonight since folks have... Notable. Why is it notable? Why is it notable? You'll find out. Talk about some of our Ada Fruit live shows, including show and tell. We've got Time Travel, looking world makers, hackers, artists, engineers, news, a bunch of stuff and more. Help Wanted, it's job postings from our jobs board, really good one tonight. And don't forget, go to jobs.adafruit.com. Post up your jobs or post up your skills and you can get a great gig from, I think, one of the more popular maker jobs we're at there. Main York City Factory footage. The stuff we manufacture here. 3D printing. High on MPI. Yay. New products. New, new, new, new, new, new. Top secret where we show some things that maybe aren't out yet or maybe they are or maybe it's behind scenes. I don't know. Who knows? Okay. All right. So your questions, we do that over on discord.adafruit.it, slash discord join all 30,000 of us over there. Oh, we finally hit 30K. Yeah. Yeah, toss your questions over on Discord and we'll answer them at the end of the show. Yeah. All right. All that and more on, you guess it, ask an engineer. Okay. All right, so that's some stuff that's going on. Let's start off with just some news and more. Since we're here in New York City, a little bit of a COVID update. What's going on? This is mostly for people who maybe run businesses. We've always shared all of our protocols and all the things that we do here. And what we're starting to see out there in our microcosm is people are getting infected after they've been vaccinated. It's mostly folks that are around unvaccinated people. Some family members or other folks didn't choose to get vaccinated and these breakthrough infections while they're not severe, they're happening. And so far, you know, we don't have an outbreak here at Adafruit, but there are a couple of team members that are quarantining. They're fine. We're vaccinated and they're doing good. And this is one of the reasons to get vaccinated because it would have been a lot worse. So that's going on in the next 30 days. New York is doing the... Yeah, you have to do the proof of vaccination. So even restaurants, like one block away from Adafruit or venues, or pretty much anything. It's not just like, oh, it's only going to be concerts or something. It's pretty much anywhere where people go. So what we're advising our team is there's three different apps that you can use right now in addition to the vaccination card. So you can always show the vaccination card. Put it in a nice holder. Don't laminate it because you might need a booster or something later. It seems to be the trajectory for that. And then the other things that you could do, there's apps on iOS and Android. One is basically just a camera app and it just takes a photo of your vaccination card. There's no data storage. It's literally just... Nothing. It's like a camera roll for one photo. So we're starting, personally, we're starting with that. And if there's more that's needed or the card, whatever will do that. And then there's the Excelsior Pass and Excelsior Pass Plus, and those are connected to the database where it has a list of people that have been vaccinated. You put in your information. And the data is already in the database. You're not uploading your data to a database. It's already in the state database. It only has a positivity result or a vaccination without it being entered into some database somewhere. It is being logged. That's just part of the deal. I get it. They want to keep track of how many people have been vaccinated. But the pass lets you pull that data back down if you prove your identity. So we're starting off with... What's this thing doing? I don't know. It's going out here. Why is it going out? I don't know. I'll turn it back on in a bit. We'll do that later. The web camera over there is tired. No, it's the thing that runs the entire Internet. So that's what's going on here. We'll continue to give updates. That's what's going on. And hopefully we can continue to get through this. It feels very much like we're back to square one in a lot of ways. We are. We aren't. Having gone to the city meeting, I won't go through the whole thing. But basically the city, they really don't want to go through another third wave because it gets cold in the winter in New York. People are indoors. And we had a massive, massive spike in the U.S. and in New York last winter. We really don't want to do that again. It's really hurtful for schools, for businesses, for restaurants, for everybody. For people's mental health. People can't visit family or they're scared to visit family. If Thanksgiving and Christmas were all around and we're still doing this, it's going to be a real bummer. So we'll see. And then just some advice for folks that might be, there's people that I know, they needed some support to make the decision to get vaccinated. And I found that if you spend time with people, you provide resources. I'm going with someone to get vaccinated later on this week. And no big deal because they just probably need another person just to make sure they get there and back and they're going to be okay. And that's what I'm going to do. And I think if you're frustrated about what's going on in the U.S. or parts of the U.S., the only thing you can kind of do right now, and this is just how I process it, is help one person at a time. And that's what I'm doing. So we'll see how that goes, but that is what we're doing because I figure if I can help at least one person at a time and so far have been able to, that might be dozens later who are more protected. So anyway, so that's the latest. Okay. So let's mention the code. Notable. Notable. That's the code. 10% off. Yeah. Just about everything in the food shop. And they get free stuff. And it's free stuff. $99 or more. You get a free promo proto half size bread board. A great way to take your bread board projects and solder them in to make them permanent. $149 or more. You get one of a variety of different stem QT sensor breakout or development boards. We are cycling these out as we can get some chips and others, but we still have a majority in stock. And if you make an account, we'll give you a different one each time. $199 or more. You get free UPS ground shipping in the Contents of the United States. And $299 or more. You get a free circuit playground to express our favorite development board. It's so round. It's so shiny. It's got all the sensors built in. No soldering required for you to get started immediately with Arduino. Go.org, CS Discoveries, MakeCode, or CircuitPython, as well as some other tiny go. Rust, TinyGo. And others, yes. I think even MicroLisp. It's great because everything's built in. You don't have to do any soldering. Just plug it in and you're ready to rock. All right. We have a whole bunch of shows. Show and Tell just wrapped up. Special thanks to Katnie and JP who ran the show and tell. They were the guest hosts this week. Watch it on all the social media places and more. There's folks still chatting in the chat right now. As we do Desk of Lady Aida this week, part one of Desk of Lady Aida was... I showed off this board that took me four days to route. I've never spent so long on a board. Usually I route a board in maybe an hour, maybe two. These are LED glasses that were route. Easily an eight-hour route. I got it done. Got done. 6.6 mil. The next thing is I showed off some other boards that I was trying to send off and I could get parts, which led into the great search. The great search, we do this with DigiKey every single week. This is a handy series because it's really hard to get parts. This is the perfect timing we came up with this. The chip I was talking about today was the LC709203 lithium-ion battery monitor chip that I designed into a lot of boards because it was inexpensive and easy to use and plentiful and that was the before times. I showed one thing I'm doing, which is changing the package from the TDFN to the BGA version so that I'll let me at least keep the designs going, but then I was like, look, I have to find another alternative chip, one that isn't end of line, one that's available, one that is affordable. We went through and actually showed a bunch of chips that were not going to be available to be purchased until like 2022 and like mid-2022 and so I was like, look, these are good chips. They're affordable. They're nicely designed, but I'm not going to be able to buy them for a year. I can't use that. We kept going until we found a chip that is affordable, it does what I want as an end is in stock, so it's no longer just one or two things. Now you have to have all three things, the right functionality, the right performance, the right price and you can actually buy it. That's the world we live in now. That's a great search. All right. We also do JP's product pick of the week every Tuesday, broadcasting live from the product page and that's where we do a discount of the product we're talking about and you don't have to put in any discount code because it's automatically- It's great. You can get up to half off of whatever product he picks. You just be fast. We have a limit of like 10 or so per customer, but we try to mix it up so there's some good stuff. Always popular products. All right. This is this week's recap for product pick of the week from JP. Product pick of the week. It is the Adafruit Pie Badge. We have this cool little Asteroids game that Todd Kurt just created and posted and you can see this is using wave playback on the audio and we have a nice little thrust and fire action going on there. So those are wave playback which is really straightforward to do inside of CircuitPython. Very straightforward. You can also see we've got some neopixels on the bottom there that light up when we hit an asteroid or when I hit one with a projectile. There we go. You can see that goes yellow or blue when I crash into one. Pie badge. It's designed to be worn as a badge. I added a little bit of cord here so that I could hang it from my board. You could also make a lovely little bracelet or hand held with it or wearable. So that's going to do it. I'm going to hang that from my pegboard. All right. And then don't forget on Thursdays we have John Park's workshop. And at John Park's workshop what you can expect is the CircuitPython Parsec segment where we do a little bit of CircuitPython. How long is a Parsec? By the way, like you just named it. Two minutes and 14 seconds. That's one Parsec? For us it is. Okay. It's an international measurement of ADA or something. Okay, good. But that's how long this video is. All right. Take it away. For the CircuitPython Parsec today I wanted to look at how you can time an event in CircuitPython to figure out how long it took. So what you can see here is a little demo. I have, it's a Feather RP2040 with a sharp memory display connected to it. And I'm running here a modified version of some particle code that our good friend Todd Bott wrote. And you can see here I'm listing the number of particles that are in the simulation or in the screen right now. And I'm also listing the frames per second, the frame rate that this is running at. Most important is that we've imported the time library. Once you have the time library imported, you can do things like this. I can set a variable called start time to equal time monotonic, which is the exact moment when you ask it. You get a unique time. That's essentially a ticker that's been counting up since this board came online. New variable called elapsed time equals time monotonic minus that start time. So this is going to tell me how much time has gone by. And I'm doing a little bit of math to convert this to frames per second. This FPS is an integer based on one divided by the elapsed time. And then I'm just printing that into the serial port. So you can see here these are taking about 0.1 to 0.2 seconds, which equates to about six or seven frames per second. And what we can do now is we can, for fun, go in here and adjust the number of squares in the simulation. So I'm going to change this number of squares. Let's save this. It's going to restart. When this starts up, you can see it's running about one, two frames a second. It's actually slower when those are all clumped together. I am not sure why. And now it's getting up to maybe four frames a second. So you can see the difference when we had 100. We're going quite a bit faster. So that is one way that you can time how long an event takes inside of Circuit Python. And that is your Circuit Python parsec. All right. We're going on Fridays. We've got Deep Dive. It's got 2 p.m. Pacific, 5 p.m. Eastern, where you can learn all about everything Circuit Python, all the things that go into it, how it's made. I think it's probably one of the few shows that brings you along the process of developing an entire, not operating system, but what would you call Circuit Python at this point? Because it runs on lots of different things. It is in a sense an RTOS. It's an RTOS development environment. It is kind of weird because it's a language, but it's also a very deep underpinning that kind of makes everything happen at the right time. Yeah. That's cool. I'd say like, yeah, it's an embedded RTOS language. The best way I could describe it, or this show and kind of the things that we do at Adafruit is, imagine being able to tune into the software team that works on macOS. Like, okay, we're going to do this feature and they're talking about it and why they made these decisions or whatever. That's what this is like. Yeah. Always a good time to tune in. And there's lots of things you can do to participate with Circuit Python. Ask questions. Yeah. We go over all that stuff more. All right. So next up, time travel. Time travel. I got to do a couple of things for time travel this week. First one is we do a daily standup meeting in the shipping department. And Lady Aida and I are there. And I got challenged to a Waste Paper basketball tournament. And I lost, so I have to congratulate Johnny for winning. And Johnny's now on the show, and I'm doing a blog post too. I came close, but Johnny is a superior player. Not that close. I came pretty close. Also, it's a bad look if I won. So I'm just going to stick with that. So anyways, congratulations Johnny. Next up, time travel. Philby has a really neat video, and we're going to try to do more of these. This is like history of some of the prototypes that you showed me. Yeah, yeah, yeah. Take it away, Philby. There's several books on Apple's industrial design and prototypes. Not surprising. A lot of these ideas are just neat. But also Apple doesn't have customers, they have fans. And like music fans who want to hear every B-side and bootleg, fans want to see these prototypes. Well, hey, I know another electronics company with fans, and I happen to have some prototypes here. Here's three of four revisions of the Adafruit Monster Mask Board from the first revision A through the final shipping revision D. And LeMore added that boobable nose like five minutes before this went to the PCB fabricator. MagTag, on the other hand, nearly identical. The power switch moved and the final one got a light sensor. And PyGamer was a months-long ordeal. We were trying to use the D-pad from a Game Boy, and it turns out that doesn't work with a laser-cut enclosure. We tried and tried. And that's why the final version has an analog joystick. Okay, next up, the Halloween Hackfest is now live. Halloween starts in August. It never goes away. Well, it kind of like re-ups itself. DigiKey and Hackaday has teamed up. I guess I always have to do disclosures and stuff. I started Hackaday, I have nothing to do with this. We're partners with DigiKey. We think it's fun, and we're just helping to promote it. Yeah, we always... These are the three coolest electronic companies. Yeah? I mean, I'm kind of doing the same thing. You know, it's just like Hackaday is supposed to celebrate and have ways for people to build and share stuff. We do that with Adafrit, we do that with Mac, and to me, this is just like a perfect combination of all things I really like. Did you get Hackaday, Adafrit? Yeah, Halloween. Anyways, so if you go to hackaday.com, it's the lead story on there up at the top. Get all the details. You can enter. There's a bunch of prizes. It is good. You probably get extra credit if you use Adafrit stuff. Just do gothy, cool, creepy stuff. You love it anyways. Okay. Get something free, or money, or whatever for it. Yeah. They have some really good prizes and more. Adabox, we're going to be shipping the next one in October. It is almost already full, so if you haven't already... It's the Halloween one. Yeah, go to... You're going to like it. Go to adabox.com and sign up. Now we will run out well before that. Let me tell you, with the Silicon Shortage, if I have the parts to make the Adabox, the subscribers get them. Other people may not. So if you want to get the coolest new thing that everyone's going to have in October, you got to sign up. Let me tell you about what it's like to be my inbox. I feel, can I have 1,000 chips? I'll do anything for these 1,000 chips. I know you have some chips. Okay, you're saying you don't have chips, but can you double check? Is there any... Surely there's just like chips. So we don't do back orders on Adafrit stuff because we like to ship what we have. And then when you order something, you know it's going to ship. But Adabox is the closest thing, so Adabox will get delivered to you. So if you want to get the latest thing that we're going to have, that is it. And the way we do it now, we don't have any leftovers. We sell through. Chip, chip, chip. We're done, we're done. Okay. Next up. Every Monday, Tuesday, Thursday, Friday, we have lab notes with Colin. I'm going to play a couple of them, and we'll see you on the other side. Wondering why your battery's dead even though you haven't been using it? Even when left completely disconnected, all batteries will slowly lose their charge over time. And certain battery chemistries will self-discharge faster than others. While they're great for frequent use, some nickel metal hydride batteries can lose 30% of their capacity per month just sitting around. That's why it's best not to use those in your smoke detector or emergency flashlights. Stick to alkalines there. Lithium polymer and lithium ion are much better at retaining charge, but can still lose several percent monthly. On a side note, most rechargeable lithium polymer batteries will ship with only 50% charge for safety. Just top them up for a few hours upon arrival. In the end, your best bet for battery longevity is still alkaline, with an average shelf life of five years. Hard to beat the classics. When the desoldering pump and solder wick just aren't cutting it, you might be tempted to try heating all the component pins at once and just giving the part a good yank. Yeah, it might work, but you might also damage the board if the solder cools too quickly. What we need is some slow style solder. That stays fluid longer. ChipQuick's desoldering alloy does exactly that. It's marketed for use on service mount components, but it works fine for through-hole parts too. Apply flux to the component leads to clean and prep the surface. When melt a little bit of alloy on each pin, it doesn't take much to work. Once heated, the solder will stay molten for several seconds, plenty of time to pull the part out. Clean up with solder wick and some flux remover or alcohol. And the dishes are done. If you look closely at a board's traces, you may be surprised at the variety of shapes and styles you find. Most of the mostly straight lines, these folded curves look a little strange, but they start to make more sense when you consider the tight timing constraints required by the board's fast processor. With signals potentially operating in the gigahertz range, trace length becomes an important variable. If the trace is too short, you may have, say, a clock signal arriving too early at an input pin. So by simply extending the length of a trace, a signal can be delayed to better synchronize with the rest of the board and meet those tough timing constraints. And all those rounded corners ensure that the trace maintains a consistent width and consistent signal characteristics as a result. Alright, help wanted jobs.advert.com is where you can post your skills or if you're a company, find great talent. This week, big job on the jobs board that we're featuring Open Hardware Summit Chair. That's right. That's a big one. So if you want to help run the Open Hardware Summit, which is going to be in New York City next year, you can. And here's your job. You can go jobs.advert.com. But just quick overview, Open Source Hardware Association is looking for a chair for the annual Open Hardware Summit set for April 22nd, 2022 in NYC at NYU. Excellent opportunity to help shape the first in-person summit since 2019 in a while. So let's find folks to do this. We'll be there because it's like down the street from us. So that's another fun reason to get this job. But anyways, they're paying. It's a contract roll. Check it all out and you can see all of the details. And they've done this for many years. This isn't like you're not going to be heading into this totally unknowing. You were a keynote at the first one. I did keynote at the first one. So you know it's good then. Yes. It's been fun every time I've gone. All right. Next up, it's Python on hardware time. Okay. Blink a, blink a, blink a. Oh, a lot's happening in the world of Python. Tons. Tons. Okay. This week, I'm going to go through a little bit of the newsletter, my pick, and then not really breaking news, but it's making the rounds today. So I want to talk about that. So anyways, if you're into Raspberry Pi, Raspberry Pi has new documentation online. They're doing a really cool thing with GitHub. So people can even do updates and more on it, which I thought was kind of cool. So check that out. We'll talk about the notable women business owners, hence the code earlier. Yeah. You can check out these cool companies. We had a circuit Python day recap. You can check out all the videos. We did live videos. We did an AMA on Reddit, show and tell. There was a bunch going on. It's all in one spot. Lady Aida did an interview about the chip shortage. We'll talk about that in a bit. We have, why is there so many shortages in the U.S.? So we sent this out to not only our team, because we talk about the very specific things for Adafruit, but why are things happening around the world with the chip shortage? You can check this out. And I hope it was full of the ending. It's not exactly COVID-related. Oh, that didn't help. Yeah. There's a little studio. There's new updates. The August 2021 update. State of Python, 2021. Check this out. Real Python podcast. Yeah. Yep. And all the normal roundups and more. Tons of keyboard stuff. Geez. Yeah. Mine's a Defcon badge. It actually doesn't run MicroPython, but it has a teeny of two bootletters. Which is cool. Yeah. That's like, so right now, if we're seeing hardware out there, if we see hardware out there, it's either running CircuitPython, MicroPython, and or the, teeny of two, or teeny USB bootletters. Yeah. Yeah. There seems to be like, here's the easiest. No, teeny USB is here to stay. Yeah. And it's free. It's open source. And we like to see more people being able to use their electronics easier. So that's the newsletter of the week. I wanted to do my pick of the week. And that is the Adafruit MicroPad, RP2040 review, the ultimate DIY keypad. This is from Tom's hardware. And they did a review of it. And I just want to... Oh, they put some jade clicks on there. Yeah. Cool about this is they're... We didn't know about this. They bought it. They reviewed it. They posted it up. Great for productivity and easy to customize. Our verdict, track design, built-in speaker, rodeo and currents, gain CircuitPython support with helpful tutorials. Stem and QT connector customizable RGB. And not height of adjustable. That's actually... You have to have a separate case. You have to have a separate case. And then screen not colored. Yeah, of course not. Well, you know, it's interesting. Well, first off, there's a TFT shortage. One of the reasons I didn't go the color screen, but also a lot of macro pads use OLEDs. I wanted to stay true to that style. Yeah. So here is... And they liked it. Yeah. They really liked it. And we're seeing a lot of people use this for things that we expected and things that we didn't... Yeah, you want me to do a thing for you. We have a lot of things. They like the artwork too. They have a silk on the back, all sorts of stuff. So that's the Python on hardware news from the newsletter. In the next newsletter, though, you're going to see some neat stuff, including this project. And I think Todd's in the chat. So this is really neat. And I'm going to just quote Todd here. Last week, I wrote a present to myself. This Astrid's like game. And CircuitPython. It runs just about on any board currently. MicroPad, FunHouse, and PyBatch. It's fun. One code file for three different microcontrollers and three different displays. CircuitPython is amazing. So this kind of shows everything that we're working on and kind of like one or two tweets or videos. And then also Todd mentions, by the way, it also runs on the Open hardware Summit badge, which is that job I talked about earlier that you could do. But it's basically four different microcontrollers, four different screens. So NRF 52A40, ESP32S2, RP2040, and the SAMD51. So here's some photos of it. I like that it works well on monochrome or color screens. Yeah. And this is that promise from a long time ago of like Genie and Java like right once run everywhere. We're getting close to this. And I really like that no matter what the screen size is, no matter what the input is. One code file works and all these things. So I'm going to play these little videos back to back. I can kind of hear Todd talking about it, but I wanted to show you what this is. And it's called Asteroids. It's a... No. It's Staroids. Staroids. Yeah. Oh, I like the idea of playing a game with the macropad. Or in your funhouse. So give it up for Todd in the chat because this is... Sometimes someone does the thing that you're like, oh yeah, like that explains exactly what we've been up to. New York architectures, multiple and different display types. All the same code. But yeah, I also got working on the Oshawa badge, which makes it a fourth type of display and a fourth type of CPU. That's Python hardware. Nice job, Todd Vaught. Yeah. Okay. Next up. Next up, there's hardware. We're open source hardware company. Congratulations, Lady Aida. You made it to the Crane's New York Business 2021 notable women business owners. You made the list. You're notable. Thanks. Oh. Notable. Oh yeah. That's a code for that. Yeah. Cool. Or if you go to restaurant, no table. Ooh. Yeah. Or not able. True. Okay. Next, chip shortages, challenges maker manufacturers. You were quoted in IEEE amongst all of the maker companies. Many companies, yes. Yeah. Not just me. It was SparkFun. It was Arduino. I thought it was cool that they actually got a bunch of different... Yeah. What kind of said the same thing, sort of, baby? Yeah. Well, Arduino said they have no shortages. So, good on them. They did say they had to do some redesigns. Yeah. Aida, Lamore, has a quote, talked about the great search. Has one of the shows that we do. Arduino. They have plenty of chips. Pololu. SparkFun. And check it all out. So if you want, because I think in the past, people have said, like, oh, how are all these other companies doing? Well, there's an article with a lot of them that you know. So check that out. Okay. Next up. There's an open source hardware company. To prove it, we have 400 and something certified boards. Yes. On Oshawa. We just did 30 more. Yeah. We're almost up to 500. But we also have 2,522 guides. So what's on the big board this week? Okay. We had some Mac-O-Pad guides this week. None Pedro off this week. They'll be back next week with more projects and guides. But they did do how to make DIY decorative resin keycaps. We have some resin keycap molds in the shop and people are like, well, how do I use these? And I kind of, I messed around a little bit, but I didn't have enough. We have a video coming up. We have a video. But basically UV resin and a couple little techniques and tips. It actually is really easy to make cool keycaps. Dylan did a project. A lot of people, well, you can also use the Mac-O-Pad, but you know, if you want to use rubber ducky scripts, these are common, like script text files that let you automate key, HAD key inputs. So Dylan wrote a whole library that lets you point it at a rubber ducky text file and it will then like do it in CircuitPython. You can just drag the file onto the disk drive that CircuitPython is. So this is really handy. Showing the Neo Trinky, which I thought would be a great little miniature LED plus capacitive touch HAD driver chip. And there's also from Melissa. This is a mega guide. Check this out. This is a very advanced guide showing, you know, people are like, well, what if I want to have like my Mac-O-Pad connected something on the internet? Because it doesn't use a Wi-Fi Mac control. It uses an RP2040. Well, the answer is you absolutely can, but you have to kind of do this thing where you have procedure calls that are sent from CircuitPython to a computer it's attached to and then out to the internet. And so she shows how to do that, having the Mac-O-Pad connected to her computer, but then she uses her computer as a gateway to control home assistant. So she can like turn on and off lights and like change the brightness with a computer via Gumbo procedure calls in CircuitPython and C-Python. Okay, next up. Main York City Factory footage taken away at the Food Factory. And it wouldn't be Main York City Factory footage unless you can see where your Disney Plus subscription money goes to. And that's the Disney building across street. I'm going to play these videos back to back. They were off today, but 3D Hangouts returns next week. Let's play their project video and then they're speed up this week. Keycaps. Hey, what's up, folks? In this project, we're resin casting keycaps for mechanical keyboards like the Adafruit Macropad. Resin casting keycaps is a really fun way to level up your keyboard making skills. We experimented with adding colored pigments, glitter and even some components like resistors and googly eyes. You can make your own set of keycaps with these silicone molds and UV curable resin. To keep it simple, all you really need is the keycap molds, some UV resin and a UV lamp for curing. We designed and 3D printed our own mini UV lamp a while back which is just the right size for the silicone molds. Start by adding a small amount of resin to the bottom of the mold which will become the very top surface of the keycap. Begin to spread the resin using a silicone pick to cover up the bottom of the mold. You want to poke around a bit to get rid of any air bubbles and get the bottom layer first so it's hardened. Use a tray with a flat surface to avoid the mold from sagging and let it sit for about 3 minutes. Once hardened, we can start to embed our components. Just be sure not to add too much stuff or things that are too big. After adding our fun bits, we can add more resin so they're fully submerged and covered up. A few more minutes of curing is needed to ensure each layer is getting hardened. Once again, we'll add more resin and this time we can start to add mica powder using a silicone spoon. You want to mix and stir it up nicely so the pigment blends into the resin, this also helps get rid of any air bubbles. Next, we'll need to add a dab of resin to the stem inside the second part of the mold. You'll want to allow the resin to seep down into the pocket and add more resin to fill it up. Once filled, you can then begin to place the second part of the mold on top of the first mold. The resin is overfilled and spilling out, it's a good sign that you have used enough resin and if it's not overfilling, you might not have enough. Back into the UV lamp, you want to give each side 5 minutes and turn it over to cure both sides. Once ready, we can begin to separate the molds and carefully pull out a keycap. Any excess resin or molding flash will need to be removed and can be trimmed away. We used our flush snips, just be sure to angle it down when you're done. We used some alcohol to remove some of the stickiness. We have the keycap over a paper towel and a squirt bottle to make it easier to apply. You'll want to apply alcohol to all of the surfaces. And there you have it, resin casted keycaps are really fun and definitely approachable. We hope this inspires you to try out resin casting and hope this helps you learn the techniques with some of our tips and tricks. So what ideas do you have for keycaps? You can let us know in the comments section below. Thank you all so much. Back to some of the keycaps this week, let's get this video off. Let's get started. This week's IonMPI is the Maxx, 22530, which is a it's a analog digital converter to 4-channel ADC and it's an isolated ADC that also DC converter on chip as well as 5 kilovolts isolation voltage. And so it solves a very particular problem, which I've actually seen where you want to measure power or data or signal or whatever or some monitoring in a system that has a lot of noise in it. Anybody has motors or maybe it's floating or maybe the voltage is different than your earth voltage. And in that case, sometimes you'll isolate your entire system, but this allows you just to isolate the analog data acquisition part. So it's actually, it's a wide SOIC, a SOIC-16, and I'll show you actually, because this is like rendering that they've got is like a narrow one, but inside is a four-channel ADC, and a lot of people, you know, when you have a microcontroller, you'll use the ADC in the microcontroller. For example, you've got a, at Mega328, or you've got a SAMD21, or you've got an STM32. Those have built-in ADCs, and often those are fairly good. They're 10-bit ADCs, maybe 12-bit. They can usually run about 100 kilosamples per second. If you are running something like a Raspberry Pi and you need an external ADC, you can use something like this, which is an I2C, or there's also SPI ADCs that, you know, this one gives you four-channels, input, cost a couple bucks. But like I said, these are not isolated, so you'll see at the bottom of this breakout to the left, it says like VDD, ground, and then SEL-SDA, you know, whatever, A0, A1, A2, A3. You know, sometimes you'll have an ARAF, you'll have a reference voltage, but that ground is the ground, like the ground is a single ground, is the data ground, is the everything ground, there's only one ground line. If you look at the layout for the Max 22530, you've got, you see on the right hand side, there's the microcontroller, and there's the SPI port, where you can see like, you know, clock, data in, data out, and then interrupt, whatever. And then there's the logic circuit, the thing that, you know, the logic interface that actually drives the SPI, and then you see that dashed line in the middle, that's the isolator. So there's an inside, there's a galvanic isolator that connects between the left side, which is the analog input, and the right side, which is the data, the digital signal. And on the left side, you can see, you know, you can measure whatever analog circuit you want, and the bottom, you know, where you see there's the ground L and the ground, sorry, the ground F. So those are two totally separate grounds. And then also the power supplies are totally separate. And what I really like about this ADC in particular is, at the bottom, you can see it says, like, micropower DC-DC. That's a DC-DC converter that's built in. It doesn't give you a ton of current. I think it gives you like, sorry, one second, it gives you, you know, three to five volts, and it gives you, I think, you know, 10 milliamps or something. It's not like a super powerful, like 70 to 10 milliamps. It's not a super powerful DC-DC converter, but it's just enough that you can do, like, the reference voltage and powering the ADC without having to have that separate supply. So it kind of takes care of a lot of stuff for you. It makes it really easy for you to do isolated ADC measurements. For the isolation, it's got 500, sorry, 5,000 volt RMS insulation rating. So, you know, you can definitely use this no matter what, like, medical or industrial purposes you've got. There's four channels, so you can, you know, do four single channel or you can, of course, do differential if you need. And here's another thing that I thought was really neat. I always like looking at these. I think we covered an industrial DAC a few weeks ago or a few months ago. And what I really like is not just like, OK, it's isolated. It's got the DC-DC supply. It's got, you know, separate grounds. It's got, you know, whatever. But the SPI itself has multiple little details in it that make it so that, you know, when you're using it, it's not just SPI data in and signal out. You've got, like, framing errors. So if you have, like, a bit flip in your SPI clock or, like, a glitch or it has CRC data, so when you're reading data, if they're, you know, you're sample wrong or something, you'll be able to use that CRC data to let you know that in your noisy situation, like your robot or whatever, you're still going to get proper data. There is an eval board available, which I picked up. And actually, this chip is in stock, which is amazing. And the eval board is kind of nice. It has a FT-2232 USB to serial, sorry, USB to SPI converter. So you plug it in, there's Windows software available that you can use to, you know, read the data and set the registers. And, like, Maxim does a very nice job where they kind of have everything available for you. So if you, you know, what I like about this is it's not like the fanciest sensor. It's not the, you know, the whatever, a new microcontroller with, like, Wi-Fi. But it does do one thing that does it really, really well. If you're doing an ADC and you need to, you know, measure a motor or an industrial situation or, you know, whatever, something where your power supplies can't touch, you don't want to have a signal coming in, you know, from your loud, messy robot into your microcontroller, you can just use this. And, like, it doesn't take any extra effort, you don't have to set up a separate, you know, isolated power supply. It kind of does it all. And a good price, too. And here's the best part. It's in stock. So you can- Is it really? It is. This is what I like. I have to pick my eye on MPIs in a way that you can get it. I will say, just so you know, the photo of this is incorrect. It's an SOIC chip. But it is in stock, available at Digikey. And there's a couple other versions that are available, too. Like this, I think is the first one, the 22530. There's also the 22531 and the 22532. And those are- Oh, hi. Those are very similar. Thank you for- Yeah. We had an exciting camera situation, but now we have a fixed camera. This is the eval-bors. This is the chip. This is what it looks like. You can see it's kind of a thick. You'll notice that a lot of isolated chips use wide SOICs. And then there's a QR code you can use to download. Live while we are on video, the overhead that we use decided to die. Right? I held it in my arms and it died. But that's okay. Nothing's gonna stop us. Yeah, you could see. It's just like, no signal. But you can't stop the signal here. You can't stop INPI. So while Lady Aida was showing this, I have another thing that I plugged in and it didn't destroy everything. So that is this week's INPI. Pick these up. These look great. Here's a short URL. And nothing's gonna stop us from doing INPI every week. So let me get us out of this and I'll show what happened. Okay. Live on INPI. All right, cool. So we use an overhead that it's really good, but I'll tell you why I don't like it. Because it dies in the middle of a show? No. I've had this for a year or so. And this is the- I wonder if it overheated. Well, no, it's this. So it's the hover cam and it's the ultra one. And I'll tell you why I don't like it because- It's a tablet. It's basic. It's just this giant Android machine. And so right now it's an unending loop of it. It powers up and powers itself down because Android's like, oh, you should just power down. So it just goes into a loop forever. Never seen this happen before. I'm gonna see if I can do anything with it. We have one from home, right? We can bring that one in. Yes, we've been doing a hybrid show. Remember, always pick up two of anything you use for a show, because it's gonna die in the middle of a show. I didn't have one to swap out here, but I do have a webcam that is good enough for what we're gonna do with the rest of the evening. Okay, all right. Well, that was IMPI. Super exciting. Okay, so before we get to the new products, code's notable, 10% off in the Adafruit store, all the way up to 11.59 PM, buy something from us so I can replace this. I know. So I can replace the overhead. Let's kick off some new products. Okay. So this week, new products let's start off with. Okay. Well, we put in these Choco keys a few, a week ago or two, and now we have the key caps to go with it. I'll show both at the same time. So maybe let's show the photos, because it's actually the Photoshop. Yeah, you can flip through these over and over. All right, so the chocolate keys are, they're not Cherry MX compatible. These are different pinout. They're different size. They don't snap into this. They're totally different, but they're really slim because the switch goes to the side, not from the top and bottom. And so you can't, also the key caps are different too. The key caps have like these two little nubs instead of like the normal cross shape. I know it looks like there's a cross shape, but it actually uses these two little nubs instead. But the good news is Kale, who makes the chocolate switches, and we stock the white clickies and the red linears. They're also like, okay, but we also sell key caps because obviously these are, these are a little rare because they don't use the standard. So we have clear, crystal clear ones. These are, they're just really clear. You can put LEDs underneath them, I guess, and you can maybe label them. They work great with all the chocolate switches, and this is what they look like from the top. And they also have opaque black ones. I kind of like these. They're a little chiclet looking, very slim. Also like the clear ones, they have these, you can see the two nubs on the bottom, the two nubs click into the chocolate switches, and so you get clear or black. These are like the really the two options. There's also like a pale white, but I didn't really like the pale white color. So these are the two options for the chocolate switches I got. Switches are sold separately in the key caps, so you need both. Here's our replacement overhead. Let's, here you go. You wanna try this out? Yeah, why not? Yeah, it works. Okay. So yeah, this is very, very slim. Let's have to show it that way. I think this is fun. Okay, so let's chuck out switch caps. All right, let's keep going. All right, next up. We did that one. Oh, you already did this one? Yeah, we did this one. I was, I was not. No, no, no, you were, you were visiting. I was setting up stuff. Okay, so next up, we have three things. They're all kind of the same. So I'm gonna talk about them all at once. So if you're making keyboard stuff, oftentimes people are like, okay, I'm gonna use some acrylic or some PCB. And maybe if I have a 3D printer, I'll 3D print something. But I noticed that I could pick up some enclosures. And these are like kind of generic enclosures for keyboards. Now, I'll say they're not inexpensive because they're milled aluminum and they're anodized and they have, you know, they're kind of custom made. But if you would like to make a four key or a two key or a four by four key keypad with either custom PCB or by free wiring, you can free wire to these. I kind of like these enclosures because they're like very well-gathered, durable. They look really good. And then we, you know, again, we don't have CAD files. We don't try to get CAD files, but we do have measurements that we've taken for you. So you can design a PCB or like I said, you can free wire it. So let me show maybe, hold on. So I'm going to be creative as well. New overhead is new. Okay. So this is just a demo of what it's going to look like. So you, for these, you do use Cherry MX switches and they snap in very nicely. And so you get four keys and you see it is, it is quite nice. Like it's a much nicer than having a raw PCB. And then on the bottom here, there's some have two screws, some have one. Yeah, I'm going to, hold on, I got it. No, I know, I'm going to. What are you doing? Well, I'm just, Are you going to do stuff? I got, I'm just adding some things here. Look, nothing is going to stop us. We are a gift. Yeah. Okay. So I'm going to open this up. Okay. So unscrewing this, it's I think our M twos. So this is a plastic piece underneath. You can see that there's a little bit of height available. So yes, you can have a PCB and the PCB will sit nice and flat. There's little standoffs. Or to be honest, you know, there's enough room in here. You can just like touch wire, you know, solder wires to the pads to a microcontroller and then just like tape it to the bottom of here sticking out. And then, you know, it's, you just have to glue it well enough or tape it down enough and then just don't yank on it. But you wouldn't even have to create a custom PCB. You could just use this as an enclosure. And once it's closed up, you know, who knows who cares. And on the side here, you can see there's a slot for a USB-C or microbeat. And let's show the two up one next. Yeah, they're not all the same. They're different in style, but similar enough, I thought I'd show this together. So this one also has a screw, an anodized aluminum. It comes in black. Just two keys, but you know, like you said, you just wanted a two key macro pad. One, two, one, two, one, two. I need that. Bottom has a key. And then again, you might have to bend the pins a little bit, but you definitely have enough depth to not stick it. I'd say I used to need that because one of the things I was gonna do is like switch different cameras, but you know. Yeah. Yeah, you can't anymore because you don't have your cameras on. Also, nice little enclosure. Okay, so that's this one, so let me put it to the side. And then last but not least is the mega. This one's really big, I'm gonna have to tilt up. Thank you for this nice camera holder. I constructed a overhead system here. No, you're 100% here, I'm talking to you, thank you. And this is the four by four, which of course is gonna give you a full four by four keypad and this one is really fancy. It's got like a flip top angle adjuster, people likely want an adjustable angle. And then also has a really nice big slot for USB connector. For this one, I think the cable is deep enough here that you would actually tilt this up. I actually kinda like this one because you can tilt it. You'd probably have the cable actually go in and just maybe glue it or something. But this one, it's really, it's quite hefty. Yeah, it has a really nice feel. This is a very fancy keyboard enclosure. And if anyone out there does get one of these and you do a model of this or what size PCB you'd use, do less now than the bottom, you can see that there's a plate and then you just free wire inside. We're also gonna have JP picked up one of our ortho pads and try it out and see if it'll fit nicely in here. But this is, this would be pretty sweet. Nice, I really want this. Anyways, so that's the two four and four by four anodized aluminum enclosures for making your own DIY keyboards. All right, and the star of the show tonight besides you, Lady Aida, our community, our customers, our team, and... Yeah, do you wanna flip to the... And the ability to make overhead cameras. Yeah, on the fly. On the fly is... The SCD 40 and 41. Okay, again, everything comes in pairs today. So this is a two for one. So let's just go through and show all the pictures. So there's the SCD 40 and then there's the SCD 41 and they look identical, except that one has 41 on the top and one has 40 on the top. Why have both? Well, there are two sensors of the same family and they're slightly different quality and so they're slightly different prices. Both of them are CO2 temperature and humidity sensors. That's right, inside is a CO2 photo acoustic sensor. It's a true CO2 sensor. There's also a temperature and humidity sensor from Sincerion who makes a sensor. Altogether, and it's very tiny and cute and it has a PTFE filter on the top. Don't remove that white filter that you see. That's not a pick-and-place tab. That's a PTFE filter to keep your sensor from getting dirt and dust into it. It passes... It's not a screen protector that you should remove. Yeah, yeah, do not remove that as we have learned. Okay, so you wanna show us the demo? Oh, no, let's keep going, let's stick here. So the sensor's on the middle and it's a true CO2 sensor. It is the next generation of the SCD-30, which you might be familiar with, the SCD-30 is a NDIR CO2 sensor, which is really popular. It's one of the few affordable true CO2 sensors that can measure CO2 parts per million in air and it is not an approximation, it's the real thing. The SCD-40 shown here, I think it has 400 to 2,000 PPM and then the SCD-41, which again, looks totally identical, is 400 to 5,000 PPM. Now most humans don't live anywhere near 5,000 PPM. I think you'd actually get kinda sick at that point. So the 5,000, up to 5,001, that's what you would use for industrial or scientific or some other environment where it's like, it's in a machine or something, it's where not humans are not, and so you have to measure above 2,000. But if you're just doing the most common thing, which is you want to measure indoor CO2 sensing for, is there air, how's the air quality, is there air flow? Are you making sure you have enough oxygen? The SCD-40 will do a perfectly fine job. That said, if there's a shortage, the SCD-40 is out of stock, the SCD-41 is just that much better. So let's go to the overhead. I got a little demo here. So like many of our sensors, it's I squared C. Hold on, I gotta adjust this. Yeah. This is fine. Is our home made? Home made, overhead. So this is, oh boy, this is not looking the OLED. Okay, so hopefully this will work out. Oh no, live demo, hold on, there you go. Why is it saying 114 PPM? All right, it has to wake up. It takes a little bit of time to wake up. But the SCD-40, we put it on a STEM and QT board, so it's got the sensor, and then on the side, you've got the plug and play I squared C connectivity, so you can use it with Arduino or Circuit Python. I wrote the Circuit Python library, it's a pretty straightforward, or the Arduino library actually comes from Syrion. They published their own library, which is great. And you've got humidity, 49%, you've got temperature, 28% or so, and then the PPM, I breathed on it, so it spiked up pretty high. But this will measure I think once every five seconds, again from 400, which is outdoors, 400-ish, to indoors you're gonna get up to like about a thousand, again maybe up to 2000 if it's a little stuffy indoors. But why use this instead of the SCD-30? Well, it's a lot smaller for one. You can fit it in more spaces, it doesn't, I think it uses less power overall. Unlike the NDIR, which I think has to heat up and do a lot of work, this one is much smaller and lower power, and it can even go into, the SCD-41 can go into a low power mode. So basically, SCD-30 does the job, it's reliable, people really like it, but the SCD-40 is the new generation, and especially if you want something wearable or small or portable, this one is much, much tinier than the SCD-30, and it works just as well. It's got everything same built-in, but much more compact, and we have it plug and play with Python and Arduino support, so it's great for adding air quality sensing to your project. And there's new products. Chainsaw blown stop. All right, so we have one bit of top secret. Yeah. So it's not really top secret now. Actually, Jepler asked, how did those panels turn out that we did, and that's the top secret for now. So I'm gonna show that. So they turned out good enough. Yes, we're working on all sorts of new stuff, but we wanted to get some older projects out the door, and so the SCD-40, we actually designed this if you remember, people watched Desk Lady and we designed this month ago. We finally got the sensors in, and this is pretty scary, because this is a panel that's $1,000 worth of chips. These chips are very expensive, the SCDs. So this is what it looks like before you put it in the oven, and I checked it over very carefully, but turns out they all passed tests. So it was a successful win, and we're gonna go put them in the store. You can pick them up tomorrow. That's top secret this week. Ooh. Okay, we're gonna answer your questions. We do that over on discordatorford.it slash discord, channel 30,000 of us. Let's go over to the questions. There was some question, there was a question earlier about what type of keycaps. If you could, I think Dr. you posted it up. Yeah, we had an exciting show, so post your questions again in case you missed it. If I didn't get to your question, yeah, I had to go and run cables and do things. We were rebuilding the starship. Can I get an eagle file for an individual key from the 30 key ortho keyboard? I need a way to rearrange them for an isomorphic hex keyboard, which has 96 keys. The keys are hexagonal, not square. Yeah, so you can download the ortho PCB and you'll see how I do it. Each key is actually a single object because otherwise it would have been such a nightmare to route the whole thing that I actually like have one eagle CAD object that contains the LED, the switch, and the diode and the capacitor and a resistor. So it, you know, you can extract it from the eagle CAD board file, but it's not, you'll have to mess with it to make it do what you want. Okay, will there be a version of MacroPad that is a full-size keyboard? I don't know, it wouldn't be a MacroPad. It would be gigantic. Yeah. Yeah, I would like to see us do a full-size keyboard. It'll just be really expensive and then we're in... Now we're in different... We're in a different category. Like we like to have stuff where it's not super expensive, it's good value, but a full-size keyboard would be pretty expensive. Okay, let's see. I've been meaning to ask about replacements for the HT16K33. I think that AC makes a couple of chips that do similar, but I like the HT, I like the whole techs. So I don't think they're discontinued, they're still available. There's just a chip shortage right now. Okay, let's see. Is a ST-4 license worth it? Don't know what ST-4 is. Solid works? No, ST, I don't know. Star, Star Trek-4? I don't know. License. Okay, questions for the show. I love the TPL5510, TPL11 boards. Is there a breakout that can do two things? One, monitor signal state change, like a magnetic switch opening, then once open it would source power to the microcontroller. Then two, keep it for at least X seconds, regardless if the signal state changes, hopefully around 20 micrograms. Yeah, I mean the TPL is the closest I've found to that, right? It's not perfect, but it does do a reset based on a, you can trigger it by touching the pin to VDD and you're gonna have that be your lead switch. Okay, a question from earlier. Thanks for reposting. Is there a best brand of MX-compatible switch, or is it basically all preference? It's really all preference. Anything on the market's good. I cannot tell the difference between most of them. I like the KL switches. Of course, Cherry MX's are great. Some people like Gateron's. You can go to the keyboard reddits and discards and believe me, go there and post this and you'll regret it because I won't tell you their opinion. It's like, what's your favorite shoe? It's like, I like sandals, feels like boots. What are you gonna do? Is there a chance that there's gonna be a Lypo backpack-style board for the QT buy? I think Scare makes one. In the chat? I think O-Tech makes one. I think you can actually buy one from folks building part of the ecosystem. Things. Are the black chalk keycaps laser engravable? Everything's laser engravable. It's just how successful is it gonna be? I suspect that it's made from ABS plastic and so I think you'll, it might be a little stinky. If you have a fiber laser, yeah, I could probably mark it. If it's a CO2 laser, I don't know. You're gonna have to just try it out and see what happens. I haven't done it. Okay, JP has an opinion about the keys. He says, chalks fit an MX plate pretty well but the plate needs to be thinner, ideally to click in place and grab with its tabs. Okay. Oh, ST4, Sublime Text, Sublime Text 4. Never use Sublime Text, but look, if it's something that you're gonna use every day, anything is worth it, right? If it saves you any effort, I spend money on tools all the time. Yeah, okay. A programmable gain on an isolated A2D. And that's a question, I think. I don't, on the, I don't think it has programmable gain. Okay. I think you do it separately. You mics, yeah, we're trying different mic setups, as you can tell. So far so good. Overhead, same old overhead. Well, no, not anymore. Not anymore, yeah. It was working at the beginning of the night. We were, we- Actually, you know, I noticed when I turned it on, the resolution that it sent off. Yeah. It seemed, I was like, that's weird. And then everything was okay. And then when I glanced over, it was going in an unending, powering itself off with this like Android message. And I think, I think it's one of those things where I'm just like, man, I wish there wasn't an entire Android operating system in my camera. That's how it goes. Okay. Let's see, I think. Everything is a Nexus 7. Yeah, yeah, it is. Some folks have some opinions and more for sublime text for, so. Absolutely. Yeah, check that out. I use Xebacks and it's not a good idea. Could the thing detect a CO2 laser leak? I think it probably could. Okay. But by the time it's leaking, it's kind of over. Okay. Could this be used for detecting, like if there's lots of people inside, you know, air quality sensor? Yeah, it's for, you know, humans emit CO2, so the more people you have inside, you wouldn't be able to count the number of people, but it would tell you if it was, if the place was filling up with people and they were breathing a lot. Okay, if we were to make a board that we don't make any more, how many would someone need to order of the TSL2591? We don't resuscitate old designs. No amount. No amount, sorry, but you can send the board files off to, you know, there's PCB places that'll manufacture design, but once we've moved on, we've moved on. That is kind of cool. You can always run the boards. The boards are there. The board files are there. And if you give those board files, like Eaglecat files, you send them to anybody that has the parts all labeled and everything, absolutely anybody can manufacture for you. It's a very easy board to manufacture. You might even be able to send it to JLCPCB as is and they would just run it. And let me hit the other chat. Discord's the best place to post questions, but. How low of a temperature could the CO2? Oh, I don't actually know off the top of my head. I think it's like negative 25, but check the datasheet. I don't recall off the top of my head. Yeah. What are the sensors that we use for our Adafruit air quality? We use the SCD30 because we built them six months ago before the SCD40s were available. If I was doing it again, I would probably use the SCD40. But they're both good sensors. They're both good sensors. Yeah, we use, we have air quality sensors, multiple places on each floor. Definitely handy now because we wanted to know how many people were breathing and the air quality is really good and it's something, I think if we can have as much circulation as possible, I think that's one of the things that kept us safe all this time. It's super raining. It's super raining now. Let me see if there's anything else. I think we just got to all the questions. And if that is, I'll do some show wrap up stuff. Okay. I think we did. Let me just make sure. Cool. All right, we made it. I got it, got it, got it. Never boring. That's right. Okay, that's our questions for tonight. Thank you, everybody. And that's our show for tonight. Thanks, everybody. Yay! Special thanks to Takara running things behind the scenes. Oh, here's one more. Will there be other versions of the macro pad with more or less keys or a different version? Yes, yes, yes. Who knows? Yes. Maybe. When will the five by six snap apart shock boards be available? Sign up and you'll be notified. Okay. I think we got it. We're making more ortho pads all the time. I think they sold out very fast. All right. Okay, I think I got to it. Okay. Oh, it's negative 10 seed is 63. Great. All right, we got it. All right, so thank you, everybody. Thank you, Takara. Thank you, everybody, behind scenes. Yay! Thank you to the A4 team, all of our community, our customers and more. Don't forget, the code is notable or not able. Or not able. Or not able. These things work as a discount code all the way up to 1159 p.m. tonight. Or not a BLE. Yeah. No to BLE. No, not a BLE. Not a. Yeah. Like it's like, oh, is that a Wi-Fi or a BLE? Well, it's not a BLE. Not a BLE. Okay. So that's it. We'll be here next week. I'll have more cameras and backup cameras as I did. This is the Phil contraption. Yeah, look. You put this together. Yes, that's right. In like two minutes, good work. That's right. Using stuff only found in the Eight of Feet Workshop. Yeah. So he's tricky adding new video input sources and live broadcasts and stuff like that. Super fun. Okay, we'll see everybody next week. Thanks so much. Here is your moment of zener. Bye.
