 and welcome to Just a Lady Aida. Hey everybody and welcome to Just a Lady Aida. We've got fun filled Saturday night. Tomorrow we're going to see a friend. So it's Sunday night. So we thought we would stream tonight. Why not get it done a little bit early? When we say friends, you know, sometimes our friends have the Prince Floppy from 30 years ago. Sometimes they make interesting 3D printed things and they're designers. Other times they run things at Twitter. Who knows who our friends are? Do you like, actually, could you like tell, cause it's shining right into my face. What? The computer, that light, sorry. What? Yeah, it's a little better, sorry. It was like right into my eye. My eye had blinded. Great, back to the show. Okay, so we're doing that tomorrow. So we're doing this show tonight, Saturday night. So let me just take care of some biz real quick, okay? Biz, okay. All right, first up, go to aidabox.com and sign up. We only have a few slots open. We shipped the winter edition in January, February. You will regret if you don't do it. Next up, people were like, hey, I saw that you got that Prince Floppy, but what was on the disc? I know there's a font, there wasn't. It's just two tiffs. That is all that's on there. Really, there was only two tiffs. One big tiff and one small tiff and they were both tiffs. And someone, you know, it's Twitter. So people were snarking on us and they're like, you don't have a trackball on your PowerBook 180 that's pristine. I'm like, okay, well, I have a replacement on the way. Like, I don't know. And you got it. I got it. Yeah, that did work. Anyways, so here you can see me opening up the tiff that was on the Floppy. But Phil, was there like a true type font? No. Was there a Postgre font? No. Was there like a font suitcase thingy? No. Or was there just a tiff? Just a tiff. Two tiffs. So here you go. And so this is the piece of history. It's now on archive.org. And so it's there. So you just see office behind the scenes. There's me, master back on in New York City and indoors so we were doing the right thing. And then I've been doing some behind the scene stuff. Just publishing some of the things that ate our fruit and more. This is our Mona Lisa OctoCat Puppet that I hope that we'll be doing a show, a kid's show maybe about coding and more one day. And then speaking of the reason why I had this out is because this is your GitHub contributions and then this is just like, you know. You can see we're in the summer. I kind of took like two months and I was like, I was a little trying to go outside a lot because I was like, if this winter is another COVID spike I wanna make sure that I get outside as much as possible when it's nice in New York, which is June, July, August. Okay. And then I've been taking photos and putting it on my personal account, twitter.com forward slash peteron. And you could see some of the experiments I've been doing. I'm hoping to do a little video show of my own but I wanted to do a max. Wait, what's the video show gonna be about? Well, you know, stuff and things. But I wanted to do this max syndrome like thing and I wanted to have it black and white and I wanted to do a lot of things. So this is kind of complicated because I can't just like do a normal thing. But I got it working. So anyhow, that's some of the stuff that's going on in the scene. So just a little bit of a reminder, Tuesday, JP's product pick Wednesday is gonna be 3D Hangouts with Noah Pedro. We may or may not do show and tell and ask an engineer because Lauren was invited to an event I can't talk about yet but it's a big deal. It's on Wednesday. It's on Wednesday, so we'll see. And so we have a few things that we've been up to. The first thing is here's these hacker CDs. These are, this is hacker soundtrack one, two and three. And what I wanted to do is see if I can use my power CD from Apple, which you could see you want to put it a little bit underneath there. So you can see this is a CD player and I have a little video that went along with it. So I got it to work with the AirPods Max. I just wanted to do some repair work that we need to do on this thing. But anyways, I got it working. Here's a little clip. Your scientists were so preoccupied with whether or not they could that they didn't stop to think if they should. Dinosaurs and man, two species separated by 65 million years of evolution have just been suddenly thrown back into the mix together. How can we possibly have the slightest idea of what to expect? Okay, lots of public culture references there. And then I guess the bigger news is we tried to get the limited edition Arduino's but you can only just buy them as a person. So I got 10 and I looked through all of them and one of them, the lowest serial number was 16 and we're gonna do an unboxing right now. We're gonna do it. And I already opened it up earlier. Do you want this power CD back? I will, you can just put it down for now. I did it, you know, I just wanted to put some photos up on Twitter. So they have all the founders, they added the new CEO, Fabio and Arduino had a little bit of a history. So one of the original founders on there, Fabio the new CEO is on there. And it's cool cause it's, you know, we got this signature thing and then I took a couple of quick photos, it's tiny. And I thought, so I thought you do a little bit of an unboxing and then I'm gonna show where we're adding this. We have an Arduino museum in Adafruit and we have a collection of things and all and I'll go over that in a second. But how about we go to you and you show us. Here we go. Yeah. So this is. Want me to shrink you down more? No, it's okay. This is fine. I agree. Yeah. This is fine. Yeah. We just, we organized this for a moment. So, okay. So there's the box and so it's got this nice gold thing. So they're going black and gold, which I'm digging. There's a little hologram here. Okay. Oh, it's so cute. And this is like a little micro Arduino. Yeah, this pops out. And there's a little foam protector and then I don't think there's anything underneath it, right? No, but if you take the box out, you could see the signatures and more. Where? The other side. Oh. Yeah. Oh, sorry. So the only person's missing is Gianluca, who was part of the original Arduino team, but there was a split with Arduino. So I get why they did this. Yeah. And these are too little. I think these are probably 0.05 inch headers. So they're, this is, you know, one quarter size maybe of an Arduino UNO. And then this is the Arduino UNO for scale. So yeah, it's like one quarter size, almost exactly. Again, that kind of fit inside. This is a little carrier. So this is like when you have a yacht and then you have a little jet ski in the yacht that can go out and then it's like, hi. Yeah, so people were asking how big it is. Well, there it is. It looks like a miniature UNO. Yeah. So, do you have anything else you want to show us? Because I have some history stuff to show about the Arduino. The only thing is, is that like, you know, for the headers, you know, it's just, it's finer pitch. But you can solder pads and it's got this cool gold. I don't know if people are going to use it or collect it. I mean, I'm collecting it. I mean, I'm just collecting it because it's cute. And it's, you know, it's got the cast-related pads. I guess I'm going to make like a mini shield. I do like the black and gold. I mean, everyone knows I love black and gold. And I'm sure this is functional. Yeah, I think USB-C and like, USB-C and there's the Arduino. Everyone's gone through a chip shortage. This might have been something that they needed to do, just to, you know, hey, we get 10 million boards out there. Yeah, and we will talk about this later. So this has an ATMEGA 16U2 as the co-processor for USB to serial, which we'll chat about. But anyways, this is very cute. So, it's history time. So we're adding this to our Arduino Museum. And let me just be really super, super duper clear. We've been doing stuff with Arduino for over 10 years. Here's Lady Eda with blonde hair. So there's Jen Luca. Left. Lady Eda, Masimo, Tom Aigo, Diver Coutelius, and David Mellis. They were at our apartment when they do for its apartment. And I have, I think, the only original Arduino team signatures. And I'm selling this on QBC next week. For $99 million. And so then I wrote an article about why Arduino won, why it's here to stay. I have to do an update because it is now 10 years old. And we have some history because Lady Eda was working on a thing where it was Arduino-like at the time. It was an FTDI thing, Masimo. He said this event that he saw, the Morris Design. So, you know, open source is kind of neat. And one of the things that we did, and the reason why I bought this little mini Arduino, is because I have a collection. So this one's going to go with our collection when Eda Fruit was asked to help out when there was the arduino.cc split. And there was arduino.org. And we were working with the US team, Masimo and team, and we wanted to help them out. So this is the panel. And Eda Fruit was manufacturing the UNOS. And I'm going to show you the first 18 seconds when Masimo was on site at Eda Fruit as it came off the assembly line with Lady Eda. And here's 18 seconds. And this is from 2015. No, I have the dates. I am an archivist. It's Lady Eda Masimo. They are putting together the first arduinos from arduino.cc in New York, USA. The first arduino UNOS manufactured in the US. Yeah. Great. Legally. Now you just have to make sure they work. OK, all right, get your testers out. Next step. And you're probably wondering, hey Phil, so Masimo and Lady Eda are holding up the very first arduino made in USA. Where is it now? Well, I got them to sign the back of it at the time. And it's in the Eda Fruit Arduino Museum. And it is a rare thing to find out in the world now. But we were making them in the USA. Here's our team. We were boxing them up. We were sending them off. And later on, they made the micro. And it says code design with Eda Fruit. They based it off one of our designs. It was nice that they put some credit on the back. Thank you. And then we made the Gemma. And that was the Arduino Gemma. We still have the Gemma. And then over time, what happened was libraries and software and code really is what drives a lot of the things that goes on with Arduino. And Arduino at one of their events said, congratulations, Eda Fruit, for being the most downloaded library. So still to this day, they don't publish them anymore. But Eda Fruit stuff is the most downloaded, most used. And people love our libraries. And we're very proud of it because we wanted to be part of this big community. You know, Arduino's in our community. We're in their community. It's one big community. And it's kind of cool that this is a lot of history here. So joining the Arduino's and the Eda Fruit Museum of all things, Arduino related and more, you'll be able to see all these things. And congratulations, Arduino, on shipping out this cool little board just in time for the holidays. Yay. OK, yeah, we got some. And that's the news. OK, cool. All right, well, for me, I got a couple things going on. I'm going to check my notes now because I was so amazed by it. OK, so we did the mini unboxing. OK, so yes, let's go to the overhead and I'll show off. I've got the Uno. So I got my prototypes in. So I started making. I made this Feather M4, Eda Lager, which I was excited about. And you can see if you look really carefully, I got a couple transistors flipped up. It's actually something that I make a mistake on a couple times. So I'm going to like this is the second time I think I've made this mistake where I have the P-channel FET on backwards because I have it in as like the ideal diode configuration, not as the high side switch. So you can kind of bend the pins over and solder it and twist it around to get the drain in the source. Swapped. And otherwise, it pretty much worked. The other thing I changed is I was using a, like I said, a high side switch for the STEMI QT connector, but which worked fine as long as the STEMI QT sensor was not a high current sensor. But the minute I tried to connect something like a CO2 sensor or a big OLED, something that used a significant amount of current on startup, the capacitors on the board would drain the 3.3 volt regular because there's not a lot of 3.3 volts. I mean, there's a lot of 10 microfarad capacitors. And if I could replace them all with 22 microfarad, it was kind of marginal. But the more you add the bigger that load is when you switch on that high side switch, you have to dump current into the capacitors. And it was browning out the chip. And the brown out on the SAMD 51, we have quite strong. We have it on at 2.7 volts because the SAMD 51 we found if the voltage dropped too much, it actually had a high risk of corrupting the boot loader. So we always set the brown out detect to 2.7 volts. So upshot is that we're replacing this high side P-channel FET with a regulator. And I'm just turning the enable on and off. And that's going to be perfectly fine. And since that is sucking power from the USB or battery, you're not going to have that risk of a brown out. Because even if it dips 0.6 volts, it's still well above the LDO voltage. So I think they'll fix it. So I ordered another set of prototypes. But otherwise, the design worked quite well. And what's funny is the chip I'm using on the SAMD 51 J20 is a bigger one than this one on the Feather M4 now. When I first designed the Feather M4, I believe it could not get J20s. I think J19s were the best chips that were available. There was something up that made it so that I didn't use the J20s. But ironically, when we booked a year ago, we booked two years' worth of chips because there was a chip shortage. So we're going to book them all. Our J20s all came in before the J19. So ironically, it's the other way now. It's like I can get the bigger chip faster than the smaller chip. So great, the Feather M4's going to get an upgrade. Congratulations. There's one bright side to this silicon shortage. But so I'm excited for this design. So I ordered another set of prototypes pretty quickly. Another prototype that I'm doing that I thought was interesting because you don't see this too often is I'm going to redesign the Vemmel 7700, which is a light luck sensor. It's an I-squared C light sensor. And what's interesting about this is that the light sensor, you see the package here, the chip itself, the sensor, actually comes in two variants on a reel. The first variant is upward and the other variant is sideways. You can actually see that this is a sideways-focused sensor like the direction which it's reading light is from the side. And it's the same sensor, right? It's just how is it packaged in the tape and reel? So one way is upright, so that would be like, so sorry, this is hard to do over the overhead. Without tweezers. It's slippery, slippery bastard. Okay, so one is upright and the upright one, it's like this. And you can see the chip up top. And the other way, the way that this particular strip comes in, the sensor is to the side. Same package, but just rotated. And I've seen this in a couple of light sensors actually. This is the alternate orientation. I've seen this in a couple IR sensors and light sensors. I've seen, they come in two versions. Basically, just really watch out. If they have two versions on a tape and reel, it's the same part number, but there would be like one slight difference in the ending numbers. And normally there's little letters that you're like, oh, this is a temperature gradient or maybe precision. No, sometimes that letter means it's flipped in the tape and reel and like, it's really useless. So that's why, watch out for that. I mean, in this case, I'm doing it on purpose, I'm gonna carry both. Because I think it's useful to have a right angle light sensor that's not a very common orientation. Usually light sensors are, you know, they point up from the board, but this one is, they're orthogonal and this one is parallel, right? From the other parallel, yeah. Anyways, so this is a version of the, you know, I'm stomach QTF-ing this that I'm gonna make one PCB two versions for it. Another thing is you go to the computer. One thing that's fun, I try to do this every year, but this year I'm really doing it is advent of code. It's super fun little puzzles that you can program. Oh, if you want to learn Python or you wanna get better at Python, it's excellent with Python. If you wanna get better with C, it's terrible for C. I mean, you could write all of these in C, but it would, I personally think it would be a nightmare. It's a lot of text parsing, a lot of like list iteration and mapping and reducing. And it's just like C is not good for that. But it's great in Python. Help you get these puzzles going. And the data sets are big enough that you're actually doing computation, but they're not so big that in Python, like I'm quite lazy, like I'm just, I'll just use list comprehension, list comprehensions. Comprehensive comprehensions. We know what you're talking about. I'll use those and I'll just kinda throw them around and you know, you're just using a ton of memory and then I throw away the data afterwards and it's fine. Do you think it'd be good for people who wanna learn JavaScript? I think so. I don't know how good JavaScript is with string parsing, but I'll tell you just to get the data in, you know, one of the biggest challenges so far, it's only been four days, but the one of the biggest challenges we noticed is like, you wanna get the data in cleanly and like that's not the hard part. So if you're like dicking around, you're like trying to parse out these strings and numbers and convert binary to decimal and vice versa and if you're like dealing with that, I just feel like you're not gonna have as much fun whereas, again, what's nice about Python is you're just, you do like file that read line, dang, you have all the data and then you strip, take off the new line, split, you've parsed it out into an array and then you can actually start working on the data once you have it in format and whatever language you use, just don't pick one that sucks at string parsing and see really sucks at string parsing. So that's why I recommend, it's great for Python learning, especially if you know a bit of Python and you wanna get better at it, which is me, I find that this is good because it'll kind of make you think like, oh, there must be like a Python built-in that does this and you know, or especially NumPy, this is great if you want to like get better at NumPy and you wanna have a little bit of exercise for it because there's a lot of like matrix flipping and inverting and like you wanna slice it, there's a lot of this data manipulation. So that's the other thing I'm doing for fun, for fun main. So that's, that's all I got for Desk of Lady Aida. Okay, you wanna do the research? Yes, let's go to the research. Okay. Where? Okay, the great search is brought to you by Digikey and Interpreer. Lady Aida uses her powers of engineering to find stuff on digikey.com. Lady Aida, what are you going to show? Okay, so let's go to the overhead because I'm actually gonna show off just the things that I've shown off. But again, in brief. To enter this word. A blurry segment? Yeah, I don't know. Whoa, whoa, so much, too much. Okay, so once upon a time, there were computers that had serial ports on them. Can you show the serial port image? Which one? Right, and then down two, down one. This one? Yeah, close that. So once upon a time, computers had serial ports and this is a 25-port serial port, maybe it's a parallel port, but they had nine pin or 25 pin ports on the back and you could send and receive eight-bit serial data plus or minus 12 volts, but then you could convert that to zero to five or zero to three volts and use that to send and receive data from your electronics. And this was amazing and wonderful and we were in the garden of Eden. And then people took away serial ports and then they were like, well, we took away your serial port but it's okay, because we're gonna replace it with a USB port. And for like about 10 years, microcontrollers did not have USB ports but they did have serial ports and so we were in this weird murky period. Nowadays, more chips have built-in USB ports and I'll show one, but if you go to the next image, you can use something called a USB to serial converter and this is one of the first circuits I made because it's very handy. It takes USB, on the left you see a USB-B type and on the right you see, there's a chip and then a crystal, two LEDs and then a couple of pads. The pads are not labeled because this is before you could get silk screen on PCBs for free. Ground, power, RX and TX. And so the chip in the middle there, which is the FT232BM, I believe, was a chip that all it did was connect to USB and present a USB port peripheral and convert that to serial and go to the computer. A lot of microcontrollers now have native USB so actually I'll show, I'll just show you this. Can you get it overhead? So a board like this, Sanity 51-based board, it's the Cortex M0 and it has USB and you'll notice there's no chip in between, it's just this chip in USB. It has a native USB converter. Compare that to the UNO, which is earlier and so, you have the mic controller and then this little chip here and it's the USB serial converter and on the Metro Mini, we also have two chips, chip USB converter and the micro bit actually also basically has a USB to serial converter, although it's USB slash serial slash JTAG, whatever, but it has a little converter chip and they're not incredibly expensive, but they're an added cost, but if you're dealing with something like a RISC-5 chip, it doesn't have native USB or some chips just don't have it and you might be stuck with the chip you have to use or you're upgrading some old design using USB serial converter and so I showed the image of the FT232BM, that one's actually no longer made. It was replaced with the FT232RL, which I also think is possibly close to being discontinued. So this, I think uses a CP, yeah, this is a CP2104 and that's another popular, SILabs also makes USB serial converters. Of course, the CP2104 was discontinued as chips are wont to do and it was okay for three or four years because it was discontinued because you still get it, but now it's really discontinued. It's been, they're no longer making the 04Y, I don't, maybe there's a little mistake in it, maybe they want to update it, so it's been replaced and then for Arduino, what they do, which I think is interesting, is they use actually a different mic controller. The At Mega 16U2, the U stands for USB. It's one of the first USB native chips that Atmel made. Now you might say, well, wait a minute, if this is, and mic controller is basically the same as this, why not just have one? Well, the Leonardo does, it kind of combines both of them, but there are reasons why you might want to have separate. We know mostly because there's a ton of code for this chip out there, like tens of thousands of projects, maybe 100,000 projects, and this is just a way of keeping it alive. And I think one of the reasons that Arduino did this, with a mic controller, is to avoid that like, oh, the parts discontinued, or we don't have control over it, or we don't want to customize it a little bit, also it can act as a generic CDC device under your special driver, a couple of reasons. But, and I'll say this is always a valid thing to do, you can always take a mic controller and make a converter. That said, I kind of like, for this instance, I do sort of like to use chips that are off the shelf that just kind of do one thing and one thing only. I'm always a little nervous when you combine two microcontrollers. I always feel like you can do it, but there's always a little bit of risk. So let's go to Digi-Key, and I'll show you the CP 2104, which is again the chip I have loved and used. And, you know, it says that it's available, but it's NRND, you know, not recommended for new designs. And having talked to Silabs, you know, it's a good idea when this comes up, talk to the company and ask them like, what do you mean by that? Because believe me, companies have very wide ranges of what they mean by not recommended. It could be, I mean, I would have the, from Silabs, the SI, I think 1143, you know, light sensor, and it's been NRND for like eight years, and I can still get it, right? But it's, they're like, we prefer use a different chip, which they also discontinued. Anyways, so the Silabs chip, it's not available, believe me, I have like the last shipment that they're making. They're like, we're done, but they do make others. And I'll say that it was, trying to search for like USB to UR, I wasn't, it wasn't as easy to find the category because it's a little, it's a weird location. So what I think I found easiest to do is just to click on the function, because it's a very specific function, and let's just view all the similar ones. There's a couple, some of which are a little bit, like this is a bit intense, but we just want active ones because we don't want to get stuck again, I think. Yeah, and so there's a couple options. So I'll say that of the chips, there are a few families. So Microchip makes MCP22, you know, they have a series of chips. PsyLabs, like I said, Cypress, maximum I've never tried, FTDI, I've used a lot. So my personal opinion is the Microchip ones are good, but they really are a microcontroller that they are reprogramming to act as USB to serial converter, which I'm not against, but I just haven't used it as much. The one time I used Cypress, it was also a microcontroller that they basically just reprogrammed and they package it programmed with USB as a serial converter code on it. And I found it was a little flaky. What do I mean by that? So USB serial converters, it's like, you'd think it only has one job to do, how hard can it be? But there's actually a lot of little details. For example, when you open up the serial port, what happens to the control lines, the DTR and the RTS and the CTS lines? And some chips toggle them back and forth or some of them they don't have, when you try to set the control lines, it doesn't quite work. Some of them only support a certain number of bot rates. So they only support 1200 to 115K. They don't support the ultra-high bot rates, like three megabot. And you're probably like, well, when would I ever need three megabot? But you will, right? There's always that once in a while that chip that's like, it really wants to be run at one megabot or higher. And that's really high. You need pretty good precision to be able to do serial at that bot rate. So that's another thing. Or weird bot rates, like 31 to 50. 31 to 50 isn't a multiplier of 9,600 or 2,400, but it's used for MIDI. And that is also pretty useful too, once in a while. You need something that takes USB serial and can convert it to a MIDI bot rate. Or on the ESPA266, I think they use like 77K bot or 77.4, something, something. So there's times when you'll get these weird, these weird ass bot rates or you have to do something with the control lines. And so I will say, I've tried a lot of converters and they're not all equivalent. They're not all drop in. You definitely want to use it in the weirdest cases that you expect to use it, especially weird bot rates, high bot rates. And control line, you know, noodling. Any questions? Yeah, we'll do a question during the great search if that's okay. Yeah. What's the drawback of using a chip as a controller in a converter? You know, it's actually probably okay these days because I think if you use like TDUSB, it's really solid. There's just, just make sure again, it does control line stuff. Make sure that it does the bot rates you want. You know, some of these are just like, you know, like the SyLabs and FTDI ones, they're really rock solid and you know, you use them and I've never had an issue. I just think it's riskier if you use your own chip, although you might be able to save a couple cents. You know, it depends on the quantities you're purchasing. Of course, it's another programming step you have to take care of. It's like another part of your production process, which might be annoying. There's also the chance that it gets erased somehow. You know, chips, if you don't set like your brownouts or if there's a boot loader, it can actually get damaged. You know, once in a wear-wear while, you know, people would get arduinos that we manufactured and they'd say, oh, the chip has, it's coming up as the DFU, the 16U2 got erased. And we can never figure out why because it would never have made it through the test procedure if it hadn't gotten programmed but something, it was really rare. Again, it was like one out of like 10,000. And we just replaced them and we, you know, we eventually did, I think, figure out we just kind of like added a secondary check or something. But it's just another thing that can fail, basically. So that said, you know, the FT series are really good. Doesn't look like there's a lot of these in stock. One thing that is in stock is the, again, I haven't tried the mix linear although I'm curious to. But the CP-2102s, I found to be very good and reliable. I like these chips, you know, and I'm revising the CP-2104 to use them. They're not fully pink compatible with the CP-2104. They're really close, but they do need an extra resistor divider, which I think is what changed. I think what made them switch from the 04 to the 02 was probably something with the voltage detection, you know, maybe there was some risk of damage. And so, yeah, the CP-2102 is maybe a little bit more reliable, right? Cause it's like, these are installed in so many devices. But these are pretty good chips and they come in, I'll say they come in a different, couple of different flavors. This is the 20 pin. And they also come in, I think a 28 pin. This is the 28. And then I think they come in a 24. And the 24 is like the default, is the default maybe? I don't remember. But look at the data sheet. Yeah, there's the 20 and the 24 and the 28. And each one is of course a larger package, but it has more like control lines and LEDs and GPIO type things. So that said, I do like the SILabs ones and like the FTDI ones. Those have been the most reliable for me. And the ones that can do the highest bot rates, you know, flawlessly pretty much. Okay, that's a great search. Okay. Oh, can you pull up my Twitter page? Cause I was telling folks, so the black and white photos, behind the scenes stuff that we're doing, and just like art stuff, cause it's been 18 months of... This one? Yeah, I mean not doing art and more. So I'm going to go to your computer. Can you scroll up to the top? Go back to the top. Go back to the top, yeah. So if you wanted to see like what's going on at Adafruit or some past art stuff, it's all in black and white. And I don't do any text. I'm using Twitter in ways you're not supposed to do, like a good hacker does. Bad tweets. Yeah, and I'm like, you know, using it to show some of the things that goes on in a day-to-day basis at Adafruit and more. There's my desk that has hack on it, a Radio Shack sign. There's a trackball. Oh, look, trackball. Yeah, and more. And so you get a chance to see. So you have a black and white photo, a black and white Mac. Yeah, and then here's Anil and Lamore. Is it a photo? And then, you know, we're around New York City and there's a pick-and-place machine. There's Central Park and there's called Little Island. So there's a lot. And this is, you know, just a few blocks from Adafruit. So you get a chance to see through my eyes all the shades of gray and more. All right. So that's a nice show, everybody. Thanks, everybody. Thank you so much. We'll be here next week. There might be a weekend where we're not here, but I'll talk to Lady Aida about that because we're gonna be out of town, but we'll see. Maybe we'll try to do a broadcast from somewhere else. We'll see how it goes. Don't forget, please go to adabox.com and get Adabox because you're gonna run out and then you're gonna be like, oh man, when you run out. And then special thanks to Arduino for shipping the thing. We bought it, don't worry. We didn't get anything from Ray. So we have 10 of these. I think we're gonna put them in the, the rest of them in the store to sell them at cost. Yeah. Because I don't know, you know, they said you can order them and I'm like, okay, well, I'll try to get them for the store and do that. So anyways, we'll see how it goes, but this goes to our collection of other Arduinos that we have throughout history, throughout time and space. Lots of things that's happened in Arduino land over the last 10 years. And really happy that we could be part of the community. And we are still and probably always gonna be producing the best type quality open source libraries. And one thing you can know for sure is if Adafrit does it, it's open source. All right, goodbye everybody. All right, thanks everybody. Later.
