 and welcome to Descalade Ada. Hey everybody, welcome to a Sunday night, Descalade Ada, it's me, Lady Ada with me, Mr. Lady Ada. It's a lovely fall weekend here in New York City. We've moved from iced coffee to hot coffee. So that's the evolution of the year until that's how you know when fall and winter's over as we go back to iced coffee. And we also did some electronics design. Phil really wanted a pink PCB and I was like, I can design something. Let me explain this. So we've done purple PCBs. Yes. We've done Blue. Red. Blue. Blue, black. And there's more choices now. We have a couple white PCBs. Yeah. They don't look so good through the oven. And we experiment with these. And we also like to figure out what people want. So by popular demand, we wanted to do something new with our feather line and more and so we announced our new feather and for Adelogger. And Yeah, did this render a little fast for you? Yeah, we wanted to see this. And so That's a nice little Yeah. A lot of Render. You know, I post it up and I'm just like, hey, feeling cute might delete. And I don't like it. So yeah, so this is great. And we're gonna continue to have cool varieties of things. And sometimes we might do limited edition for like an experimental color. Sometimes we might just like decide which color. Well, our PCB house, I'll say that our PCB house does custom PCB colors. So the purple PCBs that we've gotten for like the Metro M4, the PCB house we use actually will make like a custom Pantone match color. In fact, when we were doing the Arduino boards, people didn't know that maybe we used to manufacture the Arduino boards in the United States. And we had the PCBs made. We had to Pantone match those as well. Because the light blue color is not a standard. It's not the standard blue that a lot of people use for PCBs. So if you do order a lot of circuit boards from your PCB house, ask them if they do Pantone color matching. Yeah, for prototypes, you know, you sometimes are stuck with whatever is available from the PCB proto supplier. But for large quantities, like a thousand, 10,000 PCBs, they'll match the color for you. And they'll also sometimes do custom silk screen colors as well. Like for a Perma Proto, we have a three color silk screen. Yeah. Which is also a little bit unusual. And I'll say this, and this is not a rant or anything. So when Arduino had a big split, we helped Masimo and team Arduino USA make Arduinos in the USA because they couldn't make them anywhere else because someone else stole the name and all the manufacturing. And we had to match the PCB colors to make it, you know, officially Arduino. And when you look on any Wikipedia page, anything on Arduino, it's completely a race that we made Arduinos. Yeah, if I'll get your, that's okay. And it's fine. And I'll say this, I don't regret it because we did something that, it would have turned out really bad if this bad entity had, who had tried to take over Arduino was able to. But I'm very happy that there's an entire flourishing community of Arduino people. And for the most part, no one knows and no one cares. And you know what? It's probably better that way. That's great. So anyhow, what do you want to talk about with this design you want to show the previous design? Let's show the previous design so people can see what changed. So the reason I, you know, actually I've been meeting for, you know, a long time to redo the Feather M4. And I just been, I just, I don't know, was busy. Well, there's been a global pandemic and a bunch of shit. There's a bunch of shit. It just kind of focusing in the camera. That's at least like three months of our life over here. I know. Is it in focus now? No. Now it is. I don't know. Lock and lock. Nope. Now it's not. It's being finicky. Yeah. Now it is. Okay. Lock and lock. I did. Did I lock it? Okay. So hopefully it'll stay in focus. No, it's, wait, why is it? No, it's fine. It's, no, it's, I'm clicking the lock button, but it's not working. Hold on. I think you're fidgeting. I'm not fidgeting. I'm trying to get it to stay still. This, we might have to, Welcome to our new program. We might have to replace this camera because it's being, it's being naughty. Are you still just fixed? All right, I'll swap that out. Let's get, yeah, I think, because I've noticed lately that I pressed the lock button. I'll swap it out. It doesn't respond. Anyways, okay. So this is the old feather M4. And this is one of our first, not our first, but it's kind of a middle feather. So this is back when we're doing micro USB still, because USB-C wasn't quite popular yet. And USB-C connectors weren't inexpensive enough. They got much cheaper later, like, you know, once factory started mass mass producing them. It's got the JST battery. It's got the SAMD 51. You know, it has all the extras for the SAMD 51. Like there's this buck converter that's built into the chip that you can use. We don't actually show how you can enable it, but it's quite rare for people to use it. It does reduce the power by about five milliamps or so at the risk of the ADC gets much noisier because against your power of a boost converter, not from external LDO. And what else? You got the two megabytes flash here in a two by three millimeter USON. And then, you know, the left over space I had for Proto. So the SAMD 51 is physically a larger chip. I used a 64 pin chip and not the 48 pin chip, like on the SAMD 21, and also, you know, does have this extra circuitry need. And so that kind of makes it so this doesn't have, there's not enough space here for, you know, microSD or a Wi-Fi chip. It's kind of like just exactly not enough space. And so that's kind of why I was never like, you know, excited or really active in designing this to have other accessories on it. Like for example, you know, we have a Feather M0 blue fruit, but to be honest, you know, I wouldn't recommend putting an SPI Bluetooth module, like, you know, we have onto a SAMD 51. I would just tell people, go to the NRI 52 840, right? And if you were like, oh, I want to use Wi-Fi, I'd probably say now go to the ESP32 S2. So that said, I think having a SD card, so I wanted to kind of redesign this anyways, first off to make it USB-C, to add a semi-QT connector and a bigger flash chip, because I thought those things were kind of seemed useful. A lot of people were like, you know, the Feather M4 is weird that it only has two megabytes of flash. And when you're doing circuit Python, like, you know, your files and whatever MP3s can add up very quickly. And so I looked at, this is the STM32 F405, so this one has a USB-C connector. And then one thing I did here and also on the RP2040s, I have the STM32 connector at the end. And you can see I have a flash chip. For these, I use a SLIC flash chip, but actually ever since we started doing more RP2040 stuff, we've been able to get a 4x3 USON flash and eight megabytes at a very good price, because we're kind of buying them in bundle with the RP2040. So even though here I use SLIC for this, for the eight megabytes, I can just use a 4x3 USON. So it'll show that layout. Would you consider doing a NRF 53840? I didn't say really any need for it yet. It's like, okay, you've got two cores, but nobody's using that second core. And then, so I thought, you know, at the WQT pin, I liked the idea of a button. You know, I thought like, oh, maybe I could fit a real-time clock, but you know, it just actually didn't fit. I ended up also deciding like, well, people might want a different real-time clock and if you have one on the board, you know, you can't really select another one because they almost all use address 68. So I did kind of borrow the SD card slot and the bottom design, because again, this would never fit on the top. There's just literally not enough space. This is much larger than this. And I don't like the SD card slots that really stick out. And the bottom is kind of full, like you can't put anything more on the bottom or the board. I don't really want to. You want to? Yeah, it's mostly for layout. I mean, all the, you know, it's the ground plane and stuff. And also, you know, I don't know what else I would really add. Again, like a real-time clock, it's like whatever real-time clock I pick, some people want a different one. Like some people really like the temperature compensated ones and some people are like, I don't want to pay that much. We saw someone mention, they said, oh, could the, when it boots up and everything, could the NeoPix will be pink? And we said, yeah, sure. Yeah, I mean, you just, you could just have the default program, have it, I don't need to be pink. Okay, so let's go to the layout. Let's see. And so, let's see, it's too basic. And then maybe, all right, so this is it. So I basically, you know, the silk screen's quite simple. I sort of just took the M4 Express silk screen. And so it's not, the silk screen's not done. I just sort of like moved it around. But pretty much, you know, the left side is very similar, except for it's a USB-C connector. And the LEDs I made are 603 because I needed a little bit more space for the USB-C resistor set. On the right is where, you know, a lot of things changed. I, again, I went with this four by three use on flash chip, which can go up to eight megabytes. It's the one that we use on the RP2040 boards, like the QDPI and the Itsy Bitsy you know, we buy it in, at the same time as the RP2040 and so we buy a lot and we get it at a good price. And then over here, Systema QT, and then I like the idea of, you know, I had exactly like this much space. I was like, well, I thought having a tactile switch would be kind of handy. If you're doing an Adelagher or Adelagher, maybe, you know, pressing the button to start or stop it. Having like one user input would be kind of handy. And then I also added, you know, pull-ups for I squared C on board because I feel like if you have a Systema QT, you should have I squared C pull-ups on there. And then I wanted to make it, even though the SMD51 is not like the most low-power chip we had, I wanted to make it a little easier to do low-power data logging. And so, you know, the power for the SD card and the Systema QT pens, I go through a PFAT. So by default, it's off. And then, you know, the micro-troller can pull this down to power the I squared C port. That way, if you have like sensors or whatever, the output, you can go, you know, turn off the I squared C power, the SD power, go into, you know, your deep sleep, you know, maybe go from 10 milliamps, 15 milliamps down to like under a milliamp draw. And then you can, when you power back up, you can turn everything on and do your data logging. So maybe it's better for, it's not, again, it's not the lowest, lowest power, but it's, you know, you can get under a milliamp. The NeoPixel also, which is a quiescent current about a milliamp, I also, I power it from a pin. It's a little tacky, but I do it anyways. It's fine, you know, most people don't set the NeoPixel on to full brightness. Even if they did, the pin is internally, every pin on a microcontroller is internally current, limited to like eight milliamps or so. So those are the changes I made. And then, yeah, you know, the bottom is going to have, the bottom is going to have the SD card on the bottom. It fits quite nicely. You know, the original feather designs I made did have an SD card on the top. So I knew, you know, it would be wide enough. You know, on the bottom, it's pretty flat. I don't like to put like really bumpy stuff on the bottom of PCBs, but I think an SD card is good enough. And of course, you know, you can always, I can always make a version that just doesn't have the SD card slot that pick in place that you can just have it be fly on the back. Everything, everything on good? Yeah. So, you know, we're on TikTok and I was going to try to like just show that we're live and everything, but apparently there's no way to mute TikTok. No, never. No, that's fine. Yeah. All right. So that's my, that's my board tour. Any, any questions? No, folks were there in the chats and, and, man. What? No, I'm just saying, you know, all right. And so a little bit of housekeeping and then we'll do the great search. So Wednesday is the eight of box unboxing, a little reminder that some people will get it before Halloween and some people won't. And that's because there is a chip shortage and a global shipping crisis and everything is slow. And if this is the worst thing that ever happened to you and you're deciding to send a really mean email to our team, Just cancel now. Cancel now and come back later because it's not worth it. And you know, you watching the news, you're watching it, you know it. Yeah. There's like 500,000 containers off the coast of white California. And so that's not where the eight of boxes are but the eight of boxes were in that. And so some of the parts were in that situation. I'm just going to make a plea. Look, I'm not going to, I know some people are going to do that no matter what and I'm not going to hate you for the rest of my life but you got to chill out a little bit and understand that sometimes things take a little while to get around and we tell everybody everything always constantly. So I know there's going to be things that are going on in your life that are bad but just don't take it out on us. Find a, I don't know, a pet? I don't know. No, don't take it out on the pet. No, no, because if you have a pet, you'll pet the pet and you won't be so. Oh yeah, you can't. Come down. Find something that brings you a little bit of joy. Take it out on a bagel. Bagels don't have feelings. Yeah, because I'll say this and I worked in every type of job. You don't want to be the guy that's yelling at the waiter because you're an insane person. Like it's a bad look and that's what this basically turns into. So anyways, let's do the great search. Great. What's the great search brought to you by did you key in eight for it? Thank you so much. Thank you for supporting the great search. The great search is Lady Aida's attempt to share her wisdom of searching for parts and boy, is that a useful skill now because there ain't no parts. There's not a lot of parts. It's true. So what's the great search this week? Okay, so the great search this week is it's actually interesting. This week I had a little bit of a scramble. I had to go and find a bunch of 32 kilohertz crystals. And I know we did crystals on the great search a while ago. We did 16 megahertz crystals for a design. 32 kilohertz RTC crystals are tiny bit different. Not like super different, but you know, they're very common. There are a couple of things to look for. So I thought I would show on digikey.com and also looking for the datasheet for this chip, how to find the right crystal for this new design I put together. Okay, let's do it. So you're gonna go to the computer? Yeah, so I'm gonna go to the computer. So this board uses the SAMD51. And one thing that's interesting about this chip is you know, some crystals, sorry, some of the controllers need like a 12 or 24 or 48 megahertz crystal. Those numbers particular 12, 24, 48 are pretty common because in 16, because they divide evenly down to a USB frequency of 12 megahertz, which is kind of the frequency that a lot of USB native chips wanna use. The SAMD51 does have native USB, but it doesn't use a 12 or 24 megahertz crystal. Instead it uses a single one, 32 kilohertz crystal. And you're probably like, hey USB doesn't run on 32 kilohertz, true. But inside the SAMD51 is a phased lock loop. And that is a circuit that takes the 32 kilohertz frequency and multiplies it up to like 12, 24, you know, 64, whatever megahertz it needs. In this case, the SAMD51 actually runs at 120 megahertz on the inside and it can do that dynamically scaling by phased lock looping onto the 32 kilohertz crystal. There is an oscillator inside, but it uses the 32 kilohertz crystal to tune it to make it nice and precise. So the crystal we use here is 32 kilohertz. So you know, why 32? Because if you want to go into a low power, like ultra low sleep mode, you can actually run directly and not on USB, you can run off a 32 kilohertz or if you're having a real-time counter inside the chip, also 32 kilohertz is really common because it's a two to 15 divider of one second. If you have a counter that's 15 bits, you count up every cycle tick, you'll get to one second when it rolls over. Great. So in the data sheet, there is a little section on this crystal and they tell you here's what you need to do. This is the crystal itself, which they model as a sort of complicated, you know, LRC circuit. This is a true capacitor. This is a true capacitor and this is a C-strait. This is not a true capacitor. That's the internal capacitance of the pins and the PCB and the pads, which is gonna be very low. That's gonna be, you know, picofarads, maybe femtofarads. So basically they say, look, you know, make this crystal 32 kilohertz and make the load capacitance no more than 12.5 picofarad, which is quite common. You'll often see 12.5 picofarad, six picofarad is also very common. And then the external crystal value is calculated down here. It's basically two times the load, minus a little bit. So for 12 picofarad, you multiply that by two, you get 25 and then you subtract a little bit for that C-strait, which is again a picofarad or two. And you basically get 20, 22 picofarad, which is why you're gonna see often 22 picofarad, right? Two times the load capacitance. Now, when you're buying 32 kilohertz crystals, especially now during this semiconductor shortage, and by the way, these are not considered semiconductors, but there's a shortage of crystals, probably because people are hoarding them because if you have a semiconductor, you need to have the matching crystal. And, you know, they're not cheap, so you want, and there's not that many suppliers, so you wanna get them, have them in stock and ready for when the rest of the components come in. And so these are kind of having a, there's a secondary shortage of crystals and oscillators. So, that said, you saw in the data sheet it said, maximum 12.5 picofarad, you can go less, sometimes you can get six or seven picofarad and then just don't forget to change those load capacitors from 22 to 14, but that's easy to do, you just swap them out, you know what I mean? So, the most important thing is the physical package. The capacitance itself doesn't matter. 12.5 picofarad again is the most common, but if you're picking the load capacitors, you can go with six or nine, just FYI. I haven't had to do that yet, but I'm ready to do it if I absolutely have to. All right, so we're doing stuff in TikTok now too. Oh, there's our cat. The cat passed away a couple of years ago, that's the most bad. Hi. So, we use Eaglecat, but we also use Geekat and we publish all of our files and before anyone gets hung up on it, it doesn't matter what tool you use, just publish your files. It doesn't matter if you use Windows or Mac, you still can do open source. Don't get hung up on that stuff, everyone needs to chill out. Do you think that the TikTok teens are angry about open source life? TikTok teens are cool. They're actually chill. So, next up, someone says, how bad is the shortage, is the components are gone or they're much more expensive, both? Both, so for example, actually this is the Samdi 51 I wanted to show. This part, if you look, you can actually get, you know, 8,000 in the next two months, which is, you know, not bad. But if you want more than that, you'll have to wait exactly a year until 2022. So, it's one of those things where, you know, sometimes you can get the parts and then sometimes you're getting, I'm getting lead times about a year right now. So, it was a year back in January and it's still a year. So, it's gonna be basically two years of not being able to get semiconductors at a regular rate. I'm gonna call it. TikTok questions are great. Do you manufacture the trinkets and the feathers in New York City? Yes. Yeah, we do. Yeah. Not here in my room, at the factory. Yeah, this is our tiny apartment. It's a very tiny apartment. Yeah, and it looks like, you know, as you can imagine, this is what our apartment looks like. Yeah, it's okay. It looks like an apartment. Yeah, but good questions to talk. Mm, all right. Okay, so you wanna find this 32 kilohertz crystal. So, at the top, you can type in 32 kilohertz. Now, technically it's a 32.768, especially if you type that in 768 kilohertz. I always short hand it to 32, even though like you'd think it would be rounded up to 33. It's not. And then under crystals, okay, so lots of crystals and they come in lots of shapes. That said, you know, one of the things that makes it easier for me is all of my boards use the same size components as much as possible. Like we reuse the components. And that actually helps a lot in a shortage because you only have to source that one part. Even if it's harder to get that one, like it's easier I've found to get a lot of one part than to try to get lots of multiple parts, especially something like a crystal where there's multiple sources. Someone says, is the low part, is the low part counts the cause of things going out of stock almost as soon as they hit the store for our stuff? Yeah, it is, it's hard to get stuff. And another thing is when things are out of stock, we have people signed up to not backwards, but they get notified when we're in stock. And so the longer it's out of stock, the more people are signed up. And then when we do go in stock, it just goes that much faster. Yeah, and then some people are freaking out and they're like, well, I better buy everything right now. So it's kind of a self-fulfilling prophecy. Like I heard everything's out. So I'm gonna buy everything all the time. I heard everything's out. Yeah, that said, you know, we're doing pretty good. We're able to keep most things in stock. Some things are, you know, totally ridiculously unavailable, but most things are. Okay, so for this part, this footprint is 3215, 3.2 by 1.5 millimeters. You know, here's the thing. With crystals, you can actually go a little bit smaller and they'll probably even fit on the footprint. So if you're absolutely desperate, you can do that. That said, you know, I think I'm going to try to get a part that's exactly gonna fit. So, oh, mind me, this is 3.2 by 1.5 millimeters. So under size and dimension, I think it's visible. I'm going to do, and this is weird because it's inches and millimeters. So, three points. Well, first off, let me do only surface mount. I'm gonna answer a question while you're doing this. Yeah. I noticed that did you came to Micro Center and have stock when you folks are not? Should I wait and order from Adafruit? So here's what you should do. Sign up on Adafruit. And the second it comes back and stock, order it. You could potentially order from DigiKey and Micro Center, but usually our retail customers on Adafruit.com, they get it first. But either, either, do both. Yeah. I mean, like, yeah, do both. We try to supply everybody. That's the world we live in now. Okay, so the next thing is I'm actually going to get rid of these parts with four pads because my package is definitely, it's a two pad package. Let's see, front, that print. Sorry. This is, so this is the crystal. It's a, it's a two, sorry. This is the crystal and it's a two pad package. So going back here, let's do two SMD only. Okay, so now we're, we have only these. So now we have to actually do the size. So, okay, size dimension, three by two by 1.2 and 3.2 by 1.5. I think I was going to grab the 3.3 by 1.6 and 2.5 by 1.2, because again, I think those will probably fit on the same pads. And then finally, I'm going to select only stuff in stock because I want to get this now. Okay, so there's actually quite a few options. And this is where we can start looking at the load capacitance. Like I said, you have a couple load capacitance decisions to make and if your chip, some chips actually have internal tuning capacitors or if it took a real-time clock, sometimes whatever it's internal and they really do say it has to be six, seven, nine, whatever, picofarads. For me, I kind of want to stick to the same, like I don't want to have two crystals with different load capacitances if I can get away with it. So 12 picofarads and yeah, there's some in stock. So I can sort by price and this one is kind of nice. This one there is 51,000. I'll say that this is a marketplace product, which means it can take a lot longer. So this one is like 50 days to ship. If you do not want to wait that long, you can always exclude marketplace. Just click on exclude marketplace and then apply it. And then you'll only get ones that are like really in stock at DigiKey. And so this one by Citizen, Fine Devices, which is a great name. So they have 90,000 stock, which is great and about 40 cents a piece. Look at the specs, but it's got what I need, 32 kilohertz, 20 ppm, 12.5 picofarads, fundamental, SMD, 3.2 by 1.5. So this is good. I think that they recently restocked these because I don't remember seeing 90,000 crystals in stock before I would have purchased them, but yeah. This is, if you have a design and you are waiting for components, definitely the semiconductors and the chips of course are out, but I'm also seeing a lot of annoying lead time issues with crystals. So I do recommend if you need a crystal to order it early. You can always wait on the capacitors and resistors a little bit, but crystals are definitely, they're being hit by this semiconductor shortage. Probably it's a secondary effect, but lots of these. So this one is good. Good for all sorts of uses. That's a great search. Yay. All right, great. So a person says, thank you so much for making cool stuff. Yay. Let's see, I'll answer the next one. I know Cedar Fruit doesn't have as many solderable kits as the old days and these days we'll see solder kits again. Yes and no. So here's the thing, we might carry some. We do, we carry a couple of kits from people in the community that do soldering kits. Yeah. So the main reason is every single school facility business says we want, you know, connectors like Stemma. And so that's what we've done. Yeah. Basically to, in order to reach a larger group of kids that don't have soldering irons at school. Also another thing is a lot of kids weren't physically in school for the last year, year and a half. And so it's like people like, what kind of electronics can you learn at home? A lot of kids, you know, they don't have a soldering iron or they don't have an adult that can help them with it. And like I would definitely say it's not a good, it would be great if I would learn how to solder but I want people to do it safely. And if like the parents are, you know, busy not paying attention, it can, it's really easy to hurt yourself. So that's why we're. I think we could build people up to that. Do we, we can. In the past, you know, there wasn't all, we didn't have the manufacturing capability. We couldn't do everything for free, but now we can. So like, like stuff like circuit playground and Stemma QT and like plug and play, you know, stuff is, it just means more people can build things. And there's always soldering, believe me. There's, it's an essential skill. Someone says, thanks. You helped me get into electronics. I'm building my own synthesizers. Yay. What do you think the chip apocalypse will be over? I really think it's going to be until the end of 2022, which is terrible, but I'm still seeing the lead times stretch out. You'll be able to get parts, but it won't be like the Halcyon days of old where it's like, oh, look, the part I want just happens to be in stock. Like Amazon Prime style. It's like, oh, I need parts by Tuesday. And it was, it was just there and you could get it. You'll be able to get stuff, but it'll be like, you know, I'll show you this M51, J20. They'll be there, but in two months, like they're not there now. I will answer this one. When we start selling fruit the same day that Raspberry Pi and Apple start selling fruit and or Blackberry next up. I demand fruit from everyone. Yeah. Yeah, folks want really advanced kits. So here's the thing though. People say they want advanced kits. You should look in the Ham radio community because like, yeah, there's like, if you really want advanced stuff, that's a- Ham radio, synthesizers, keyboard kits. Check out, of course, there's a large community of people making kits on Tindi and Etsy. You don't have to get them from us. We did our time with it. You know, we had the $350 advanced kit. I did it, I did it for four years. I'm glad I did it. I'm doing something different now. Next up, due to the supply issues with MicroBits, can you suggest a good alternative for kits? Yep, get a clue. We have them. We have clue and we have Circuit Playground Express which works with Make Code and works with Circuit Playground, Circuit Python works with Arduino. We, it's funny, it's like when we designed the Circuit Playground Express, which is actually fun. We're at a stock at this very moment. We're gonna get some more in a week or two. We have the Circuit Playground Bluefruit, the Bluetooth cable version. Folks have asked what's the process of designing a new microcontroller board like? Where do you start? I can tell you, go to our Maker to Market series where we designed Circuit Playground Express from chip all the way to tens of thousands, if not more, already shipped out in the world. I actually recommend, if people wanna design their own boards, go to one of the designs that I posted on GitHub and take the EGLE file. You can always import it into KiCad or you can just open up an EGLE and trace over it in your whatever format and then use that design because the designs that we publish are always post shipment, which means that we know that they're at least manufacturable and they pretty much work. I'll say like, yeah, once in a while, we make mistakes, it does happen. But like when we published our RP2040 design, people used it and they made their own RP2040 designs and believe me, we had already, we were on web like four or five. We already tried and screwed up a whole bunch of stuff. If you want to do that, doing it straight from a data sheet, you can do it. You're going to make mistakes and if you just want to kind of get going, it's a little bit like, I was looking at art blogs and people are like, oh, some people can draw from seeing and some people have to draw from, they trace over with a reference. It's okay to draw from reference. It's like you will always add your own flourish and your own art style to it. If you take Adafruit designs and then carry them apart and then rebuild them, at least you don't have to worry about did you get the right values, the right amount of capacitors? Is the power pin connected? That's open source and you can do whatever you want with it. Except what are your thoughts on, microfiber number C seems like a better way to learn a little bit of programming. They both have benefits. I'll say that C is a little tougher, I think because you can hard fault and you don't know what went wrong whereas embedded languages like Python are very good for fast iteration. You can very quickly get your project up and running because when something goes wrong, it doesn't just hard fault and your pointer goes off into La La Land and your memory management is all screwed up. You'll get an exception printed out that said, oh, you tried to divide by zero or like, oh, that file doesn't exist and it'll be a very nice printed message on the REPL and I think that's really valid. So I would actually recommend for a lot of people build your project in embedded Python first and then if you need better performance and speed then you can port it back to something like Arduino or C or C++. Okay, next up, would you be interested in making a Max 25205 board, just your sensor? 25205, I don't know what the 25205 is. I'll send it to you after. Yeah, sure. Next. I like the APDS and we just put in some VL53. Okay, make you make these a little pricey for essentially a USB keyboard controller and each of your alternatives. I mean, any of our trinkets. Yeah, I mean, it's nice because it's kind of ready to go. What you're paying for is it's like the website and the experience. You can definitely take a circuit playground or a micro bit and it has capacitive touch or circuit playground classic and express all the capacitive touch on the pads but it's like, you're not gonna get something as easy to use as the Mickey makings. You have to load code onto it. Okay, question. Is a MOSFET okay for NeoPixel level shifting? Yeah, it's just gonna be inverted. So just make sure that you're either you have two or you are in your software if there's a way to invert the signal. All right. And I wanna thank Scott Haselman for sharing our live broadcast. Oh, hi Scott. I'm trying this new, you know, this thing. So right before we wrap up, I'm just gonna see what happens if I click this button. There's like two cameras in there. All right, so it has flip camera and mid settings, comment, topics, gift, support and nonprofit. Okay, the next one is a power button. I think that's to turn off the stream. I'm not gonna do that. I have enhance. How is this TikTok longer than a minute? Because you can do live. Okay, so there's different filters. You can do shape, I can smooth you out. I don't like this. Smooth me. Okay, and then there's this other button and it says send to. And I guess I can send it to other people on TikTok and then share to other places. And then there's this little button that says add guests and add host. Yeah. So for everyone on TikTok, can you hit like or whatever's good there because? Hit the talk button. Yeah, because we do electronics and stuff like that. We're certainly not eating Tide Pods or anything. So it's hard to compete with a lot of things on social media for people who are doing education. But if you hit like and share or something like that, I think that helps us. I don't know. So you can't stream this, the way you stream through to TikTok. Not yet. Yeah. There's a periscope. Remember you had the periscope? Yeah. And like I showed the behind the scenes here. I'm just like, this is what it looks like behind here. Hi. So anyways, thanks everybody. I'm gonna stop the TikTok thing, but since there are a lot of people watched it, I'm going to try to do this each time. A lot of us, it depends if I'm tired. There's a lot of stuff going on. Yeah, there's a lot going on. All right, so I'm gonna hit this button. Bye. Okay, they're currently watching. And now, thank you everybody. Okay. And that's our show for tonight everybody. We'll see you. So many cameras. Next week. Hi, everybody. Wednesday. Keep it safe. Shown tell some 30. Yeah, pink hair. You gotta get my hair re-pinked. Eight o'clock. We're doing the unboxing for AidaBox. We've got Deep Dive. It's gone on Friday. We got 3D Hangouts on Wednesday as well. And we also have JP Show on Tuesday and also on Thursday. See everybody next week. Thank you so much for supporting a USA manufacturer in New York City. Bye, bye, bye, bye, bye, bye, bye, bye, bye.
