 and welcome to the Desk of Lady Aida. Hey everybody, and welcome to the Desk of Lady Aida. It's me, Lady Aida, and welcome to my desk. With me is Mr. Lady Aida on camera control. Word to your mother. Ooh, it's right, it's Mother's Day. So for those who are thinking about it, maybe call your mom. If you don't want to call your mom, believe me. I understand, you don't have to, but if you want to, I don't know. It's up to you, you decide. But once you're done with that, come on by and we can hang out at my desk and look at electronics. Yeah, we've got a lot of stuff going on this week. You can see some progress that we have. We're posting across all the social media channels, pretty much 24 seven, but Sunday is when we kind of collect things together to figure out what, when, and if we're gonna release something. So what's on your desk this week? Yeah, let's look at my own desk. I set up a couple things. I was actually working on some electronics this week. So first up, I think I showed these, this is a Zippy navigation. Yeah, that little video is gonna come out probably tomorrow. But that's okay, I can do a live demo tonight. You can do a live demo. Might wanna move the camera physically a little bit. Sorry, I forget. There you go. Okay, now it's zoomed in. Okay, so this is a click scroll wheel. It's reminiscent of the iPod. It's not the same one as in the iPod. It's made by Zippy. It used to be made by, I think, E-Switch or something, but Zippy makes, which they make a lot of mechanical stuff. They make a version, and it's got a rotary click wheel in the middle, and it's got four buttons, you know, Northwest, Southeast, and then one in the center. Got hooked up here to a Feather M4, and it's just reading the rotary encoder, and as you can see, it's spinning a Neopixel to match. You can maybe hear a little bit of the clicking. And then there's, if I press the up or left or down or right buttons, and then the center turns the whole thing on. So there's a little demo showing this breakout because the board is like it, the sensor itself is like a totally ridiculous pinout, and so this is just a little adapter that makes it breadboard friendly. So not a big deal, but you know, I wanted to, I wanted to start playing with this a little bit more and, you know, to test the footprint, I was like, I might as well make a breakout. So I did that. So that's one thing. I also put together this prototype, which I was distracted by Trinkies. And, you know, it's also like TFT's got really expensive, and they're still really expensive, but I wanted to finish it off. This is a 1.69 inch IPS TFT display, and you can tell it's a rounded rectangle. So it actually has the pixel cut off, like it's missing pixels. It doesn't have like a, it's not like a different mapping. It's just like, there's just a cut out basically. Do you think that's because the actual iconography is all rounded corners now, or is there, why is there? It's just for smart watches. This is so you can fit it into an enclosure. And so instead of having to work around that with a physical design. Or you'd have to make it bigger. You'd have to make it a little bigger and then make it look like rounded corners. Now the screen itself does rounded corners, so. And so you don't have to worry about the, it just means your case can be a little smaller. Gotcha. Yeah. So this is a few folks who remember, we were experimenting with, we really like quick and STEMIQT, which is plugging in, I squirt seeing here is like the rotary encoders that we used to put in the shop. I squirt see stuff connecting with four pin wires. Grove does this, STEMIQT does this, but for SPI and displays, it was something that we were starting to get all annoyed by. It was like every display had like, you know, the hardware SPI and then like, you know, a chip select pin, a data command pin, a reset pin, if there's an SD card pin, you know, there's a chip select for the SD cards, there's a touch screen and another chip select. And so it's like, it's not like just I squirt see where you're like four pins and done. You actually need like a lot of pins. And we saw that DF robotics, who came up with a standard that they called, I think it's just like generic display interface. I don't like you really have a name for it. And I was like, well, that's a good idea. And I like to stick with other people's standards so that, you know, I don't like to invent new standards. It's not really not my favorite hobby. So on this display, we have a little flip top for this flex cables. Flex cable has 18 pins. And I always like the bottom contact type because it's, I feel like it's easier to insert. And then if you plug this in, it'll show. I don't think we got to show that we actually have a logo that you designed. And you can see it's being inverted, but that's the iSpy logo. So SPI flex for display connectivity, putting on a, you know, a 20-cent connector on the back just means like, look at how easy it is to connect a TFT display a lot. Like there's such a pain to wire, but really the pinouts are very standardized. So this actually got done this weekend. So this is ready to order. And I got the pinout right this time. So good for me. That's SD card being tested. Um, what else? Some keyboard stuff showed up. So my break apart ortho key PCB. So you can actually see, you know, this has the routed cutouts. I haven't tried breaking this apart yet. I'm a little nervous to do it. I have a couple of these PCBs in a lot, but you know, in between, there's a little bit of a couple of very small holes and the two traces that connect each one to each other. So I'm hoping that, you know, you'll be able to easily break this apart and make custom ortho linear keypads. And then, you know, you're plugging your cherry MX keys into the kale sockets and there's a new pixel on the bottom. So check out the previous videos for this. It's got rows and columns and it's diode matrixed in between. Okay. For that connector on iSpy. Yeah. Are you going to do a great search about it or like what about it? I kind of covered FPCs already. So I don't think I'm going to do a special one just for that. What is that connector called? It's just a sort of generic 18 pan FPC connector. If you look, one of our first great searchers was about FPC connectors and just instead of 40 pan or whatever, I picked pick 18. Okay. I also got the PCBs for the MacroPad RP2040 designs. This is going to have like an OLED glitter encoder and three by four keys. So we just got these on Friday. So I haven't had a chance to put them together yet, but I think I will do that soon. On our blog and on the social media, as we posted up our take on the Arduino Pro Micro size boards, but we're doing RP2040 for the Keeb community. So we're just calling it like... This is Keeb. But this is all in one. This is like a Macro. So there's a lot of keyboard stuff going on. So that'll be something to check out. Why? Because mechanical stuff isn't stopped. That's why people are like, why are you suddenly doing all this mechanical stuff? Because I can get them. There's no parts shortage. Some more keyboards. There's no shortage of chips, but as long as I can get any chip, in this case, the RP2040, I can make a MacroPad because every other component is a common jelly bean and I have enough stock. Speaking of the Keeb, so if you want to go to the computer and we can show off the keyboard design that I did yesterday night. So after a while, like I just couldn't watch SNL anymore. Like I didn't... It wasn't that funny. So I came upstairs and let Phil suffer through it. And I designed a circuit board instead. So, you know, everyone's loss is your gain. So the segment that you missed, and you can watch it online is the Pete Davidson character Chad. He was stranded on Mars. There was an issue of oxygen. Yeah. Elon kind of plays himself with that. See, I think Elon can play himself. I just don't... Yeah. He just doesn't need to play anybody else. So I think that was one of the funny ones. I'll check it out. Yeah, you can do it online. It's on YouTube. And I did think the... You know, anytime people dress up in any type of Mario characters, doesn't even need to be funny, but it looks funny. It does look funny. And that sometimes physical humor is all you need. Yeah. Okay, so doing keyboard stuff, and people really like using Adafruit boards and keyboards, and we've designed itsy-bitsies and I noticed that itsy-bitsy, the pinout never cut on with keyboards, even though I thought it was like kind of cool because it had more GPIO and it had a NeoPixel driver pin and a V High available. But it turns out people really like the Pro Micro pinout. And so I thought, okay, well, since so many people are using Circuit Python with the RP2040 make keyboards, I should make a Circuit Python happy RP2040 board. It's basically like the... It's eBitzy, but it's got the pinout of a Pro Micro. And thankfully it's actually... I always find it kind of amazing when the pins just sort of like magically fall into place. Like this is a very... This really was a very... It was like a lot of flow. Like I felt like really like it was happening because pins like zero through nine on the Pro Micro are down here. And those match up zero through nine here. Like they're like one in a row. And even the alternative function. So the TX and RX pins are like... TX, RX, SDA and STL and it's exactly the same as the Pro Micro. So it's like, even if you're using the UR or iSquert C peripherals, it's like a drop in replacement, which I thought is sweet. One thing I did change, and this is the big thing I changed with the design is that Pro Micro doesn't have a pin at the top, which I'm not sure exactly why, but there's actually like one pin gap missing. And I added it back and I made it connect to D plus and D minus because I noticed a lot of people, it's like they want to make a keyboard, but they may not necessarily want the USB-C there. They may want it to be connected to like another keyboard or, you know, I don't know. Like they want it to go through an enclosure and then there's like a panel mount. And also the old crow is always asking, like, can you put the D plus D minus pins? And I know in Pedro also I see them. They make projects, sometimes they end up extending the USB out for some reason. And so I thought, you know, as if we have these two slots, let's add the two data pins. And then I also put a jumper here that lets you short out. There's a fuse and a protection diode. And those are good, but like if you want higher current, I wanted to give people an option. So this lets you short them, which basically just means like, you have to be a little bit more careful, but it's not a big deal. And then it's got the eight megabytes of flash memory over here, the RP2040 chip. It's got a NeoPixel here. There's a power LED, but it's interesting, the ProMicro doesn't have a D13 LED that I can notice. So for the boot button over here, I put that diode in that lets you use the boot button as a user button. So that's kind of nice. And then Sparkfun made a ProMicro of the RP2040 and they put a STEMI QT quick connect on the end. And I was like, that's a really good idea. So I grabbed that idea from them. So this is a little bit, and then it cast a little pads like the Elite-C, which is a really common keyboard microcontroller. So I kind of like, I picked a little bit of everything and I was like, okay, well, I don't really know what I'm doing, but I think this could be a good design for people. And it fits all on a double-sided board. So it should be pretty inexpensive. And there's a good ground plane and there's like lots of GPIO. So I think, you know, most keyboard designs have settled on like, you know, you should be able to do them with the number of pins available on a ProMicro. So I think this is good to go. Yeah, and we do have a person in the chat that I agree with, I've seen this a lot over the years, is the cheap clones of the ProMicros, the USB ports is ripped right off. Yeah, I've always preferred, I never liked having service mount only USB, you know, USB, micro, USB, but these USB C's, you see that there's these two holes. You cannot rip them off fully, but you will rip off the PCB before, like it will delaminate before you pull off the USB. It is so strong. I have Mr. Lady at a test that for me. Yup. He does that. Okay, what else? Okay, so that's this keyboard. It's called the KB2040 for lack of a better name. So that's that. And it should just come out, it's exactly like the itsy-bitsy or the cutie pie. It's like the exact same design. Just like with a lot more ground pins. And then like there's, you know, a raw pin over here. Okay, great. So that's, that's that. And then, okay. And then lastly, let's go back to the overhead for the last thing. Before we... We're gonna show the... Oh yeah. So, right. So, and also last week, we talked about this pin-up generator. And we actually got some pin-up generating this week. So, you know, we, Phil B worked on this a lot. Kattney worked on this. So the colors that are picked there, these are actually not just any colors. These are picked from a specific palette of colors that are readable, no matter what kind of color blindness you may have. Like if you have Trionic or Bio... I don't know that there's three or four different kinds, but these are like really safe colors. So they're very beautiful colors, but they're also really accessible, which is great. So we started with the RP2040. And then I've also got here, I'm working on the ESP32S2. So again, for every chip, there's always a little detail, something I have to kind of noodle around with to make it work. So with the ESP32, unlike the RP2040, one of the things about it is not every pin has every function. So you see like these pins have, this is called the power domain. So it's like, whether you can use an RTC mode or not like in low power mode. So the nice thing about the RP2040 is every pin has a PWM output. Every pin has an I squared C, and every pin has a U or every pin has SPI mux. Like they just completely cross-barred the whole thing. But with the ESP32, it's like there's some pins that are special high-speed SPI. There's some pins that are touch. There's some pins that are debug or have crystal output. So there's gonna be these gaps in between. So we're still working on that. But you can see like here, these are DAC pins, but they don't have the high-speed SPI or something. So, but it looks good so far. Like I'm liking the look. So we're gonna do some ESP32 S2, and these are the pins that are like floating. So like these debug pins are actually like right here. You can kind of barely see them. And then this neopixel pin is actually for the neopixel over here. So we're gonna have to like point to them out and be like this is a pin for internal connections, not an external connection. But so far the automatic generator is working really well. So the nice thing is like this is all fully automatically generated from the fritzing file and the circuit Python pin alias name file, which is how I determine like what we call the pin. You know, it's like what is the neopixel pin called? I know it's pin 45, but what's like the human friendly name? It's neopixel. So there's a lot of pins that have friendly names like MISO and S-Clock and VDIV and A2. So all of all the friendly names were parsing out. Yeah, so that's what we're gonna be more. We're gonna keep working on that. It's like happening. And you know, there's folks that are colorblind in the chats and they're like, thanks for doing this. Yeah. We'll always do the best job we can for absolutely everyone. One thing, and I wanna thank the community is people assume the best in us. Sometimes we don't get to everything right away or we'll be updating something, but we always go out of our way to help people. We don't go out of our way to exclude anyone. So thanks for cutting a slack. Cause like once in a while, like we'll have a graphic or a chart or something where like, oh, let's make sure it's good for everyone possible. But you know, sometimes we just need to update stuff if we didn't get to it or if we missed it. Yes. So do you want to go over to, is it great search time? No, not, not quite yet. All right. Cause I see Digikey and I'm just like, I know, but I was actually gonna look something and I realized it's not there. So let's just go to the other head real fast. We're really almost done. We're ready. That's fine. We'll scrap it off. It's your show, do whatever you want. Well, I wanna kinda make sure that we get to everything. So with the CESA boards, which I'm loving and we just got the Wodering Coder out, this is like a three year old project and I finally finished it. So the Wodering Coder, you know, we use the Wodering Coder and it gives you the values where I squared C and there's a Neopixel. Wonderful. You know, we just put them in the shop. We're gonna be making more. The chip that's used on this is the Samdio 9, which, you know, until a few months ago was like extremely plentiful, like water, raining from the skies. You could get Samdio 9s. You had these very inexpensive Cortex M0 chips. I really loved them because they were very fast. They had a lot of RAM, a lot of flash and were very inexpensive. I was getting them for a great price. I got a great price from Microchip for them. But then you can't really get them anymore. So I have some stock, right? I have, you know, I don't, I'm not like the car companies. I buy stuff and I broker it ahead of time and like we have some coming and we have stock, but I have a huge pile of all these seesaw type boards, not just the Wodering Coder, but I wanna make one with like this encoder and I wanna make one with like a joystick and I wanna make one. Like I have all these like little Y squared C to button thing, you know, again, mechanical stuff. And the chip itself is, I'm a little hesitant to design, if I'm gonna be designing the PCB, I might not pick a chip that I know I'm gonna be able to get a lot of. And, you know, I looked at, we tried about this, I looked at the MS51, which is the cheapest microcontroller on Digikey. Like you search for like, microcontroller with like eight to 16K of flash, nothing is cheaper than this. It's 30 cents. It's like dirt cheap. And it has some nice benefits. This is also a chip that Pameron uses in there, like I squared C. They have a seesaw like thing, which I don't know what they call it inside, but it's not open source, I think, but it's like, it's an MS51 if you look and then they write code on it to do I squared C stuff. One of the things that's nice about this chip, other than the fact that it's 30 cents, just like amazing. And I'm sure you can get even cheaper if you go direct or you have a broker, is that it can do three or five volt logic and it's five volts safe. So, you know, one of the things that I have to do on all these boards is because people are using these with an UNO or they're using with a mega, they're powering with five volt and they're using five volt logic. So I have to have a logic shifter and regulator and it would be kind of nice if I could skip those. Again, I have plenty of regulators and shifter chips, but like it is an extra 30 cents ish, 20, 30 cents. And it's another thing that I won't be able to get. So I got this dev kit and I was like, yay, I'm going to get this. And then of course, like all the MS51s disappeared from the face of the earth and the lead time is two years, which is... What's a seesaw for the folks who don't know what seesaw is? Oh, seesaw is the firmware that is on this little chip that reads the rotary encoder. It's a microcontroller, it reads the rotary encoder and then it has an I-squared C interface as a peripheral. So you can read what the value is. So it's a like I-squared C to anything converter. So it's a firmware so that, you know, because like an I-squared C and non-digital converter is like, it's like a dollar. It's like, it's cheaper to get a microcontroller programming with your custom firmware. And for stuff like this where it's, you know, you don't need heavy duty specifications, it's good enough. The problem is that the same DO9, like I said, it's evaporated. So I looked around and I was like, I spent like an evening and I was like, what's a chip that I'll be able to get that's inexpensive and five volts? Friendly and so far, I think the thing I found was the AT Tiny 817 and 816 in that series. So it looks like there's gonna be a lot coming into stock at DigiQ soon. Like I kind of did the thing where I, you know, I checked the lead time, it's three to five volts. It's got I-squared C peripheral. It's one of the new AT timies. So one thing that I thought was really neat. So the programming chip, I thought like, oh, does it use like the SPI? It actually doesn't, this is SPI, but it's not, it doesn't use this for programming the chip. The chip is actually programmed with an asynchronous serial protocol, which I thought was really smart because you don't need special hardware to do asynchronous serial. You just need one resistor and a serial port, which means that I could, even without a boot loader, you could plug in, you know, I'll look maybe I can write a boot loader, but you can plug in to these pins and maybe short a jumper or two and then use the same wires connected to, you are on my controller to program in the chip, like raw, like program the chip completely, even if there's no boot loader on it. So I thought it would be kind of neat in case people wanted to upgrade the firmware on these little boards or like, you know, somebody finds a bug once in a while, I can fix it and send them new firmware. So I'll do a great search about how I found the 817, 816, but yeah, I think this is going to be what I want to use. And I think I'm just going to have to redesign the boards before I get them into production because I do have a stash of Samdeo 9s, but I don't know, they're going to last a whole year, especially if I come up with like 10 new products. All right, speaking of stuff out of stock, it's time for the great search. Where are you? The great search brought to you by DigiKey and Eat A Fruit DigiKey, thank you so much. More so than ever. The great search is now becoming the most popular segment across all of our shows because before, back in the time of Plenty, it's like, oh, why do you need a search for anything? You can just find chips everywhere. They grow on trees, not anymore. So we tweet at us and use like Pound, the great search, or At Us, At Eat A Fruit, whatever ways, let us know what you're looking for. And we're also out there helping people. And we saw- We see things, we help things. We saw this one. You want to start with the tweet? Yes, so we saw Tobias tweeted, and there's lots of Jerry who had like a headache-y gif about like how she's working on design and can't find a part. And Tobias says, welcome to the club. Anyone, TPS 27081A for 15 bucks a piece, usually 30 cents a piece. So they're talking about how brokers are, you know, have seen this. Like some brokers are what I would call ethical. It's like they'll charge a little bit more because it's rare, but they're not going to charge a ridiculous amount. Or like we're seeing 10, 20, 10 prices. I like not putting people in, you know, you can resist anything from, but temptation. And so I think right now there's a lot of temptation for a lot of folks who do broker in your parts to charge whatever. No, I have to actually redesign a couple more. It's not gonna be a deal, I'm gonna do it anyways. But it's like, okay, I'm not paying $15 for example. I've seen it, I've seen it. I've had people quote me like five, six, seven, eight dollars for parts that I'm like, that's a 70 cent part. Like, I can understand like, hey, 50% more, you know, ooh, like I wanna make a couple bucks, but I'm not gonna pay it. Like if they find someone great, but I'm not gonna pay it. Okay, so what is that? And I'm saying you shouldn't pay it either. Instead you should tag us on social media and we'll find you an alternative. We'll find the alternative and that's one thing. Just because it's not the same part number that you're used to doesn't mean- Correct. It's not something that you- Sometimes the part number is similar, but sometimes it's not, I don't see here. So this part is an I2C power switch, normally 35 week lead time out of stock completely. And yeah, it used to be about 30 cents a piece. So look at the data sheet and so we can see what we're dealing with here. Cause I've never used this part. So this is a 1.2 to 8 volt, 3 amp P-FET high side low switch with level shift and adjustable slew rate control. So basically you can use this, there's a V in coming in and then there's a GPIO logic high and low. You can put in a slew rate capacitor here, a slew rate resistor here to how much you want to feed this, this FET and it will turn on. So it's basically like it's like a P-FET but it's like it's got a little bit extra in it just to make it special. Also it's 1.2 to 8 volts and it's 3 amps. Now look, I may not be able to get you the exact same part but maybe it's within the specifications you need. So let's use and I wanna highlight there's a couple things. So there's new up here right below, not in stock. You can sign up for start notification where they email you, which we did on Adafruit so I hope they were inspired by and also find similar parts and they tell you how to use the similar parts tool which I will tell you as well. So let's look. So what do we want? So we want an active part. I don't want to say general purpose because I actually don't know. We do want it with one output because we want it to be pin compatible. We want to be one to one high side. I think I want the interface to be on and off but I'm not sure. Voltage I'm not gonna select because there might be a wider range or a range that's close enough so I'm not gonna be too specific. Same with the current. I'm not to be too specific. I do want surface mount and I do want it to be in SOT 236 or T SOT 236. So let's be similar. Okay, so another thing is down here. These are now all your specifications that you picked are also available down here that you can turn on or off specific ones or you can delete the whole thing so you can see more clearly what you searched for. So we're gonna be very picky. We only want ones in stock. Okay, there's only 13 similar-ish parts. The output type. So let's look at this chip again to see what is the output type and it says it's a PFAT. Okay, so let's go back here. XP channel. Okay, there's eight. Current output looks like there's a couple options. Voltage load, I mean, I think other than the 5.5 so the 5.5, I mean, it might be good enough but I'm going to assume that they want up to eight volts that usually the high limit is what they want. So I'm gonna turn those on. Let's look at more filters. Okay, so we have actually quite a few options, right? So this is really good stuff and a lot of them are in stock. So let's look at, they're all on off. So it looks like we have a couple options, a couple of different current options. So since we have a couple of different current options, I'm gonna start getting picky and I'm gonna say the other one was a three amp. I'm gonna assume that this person needs something that's about three amps. So I'm gonna pick only 2.8 and 3.3 amps. Okay, so here's the two that came up. One is almost the same, 1.8 to eight volts. Another one is 1.5 to 12 volts. They both have an RDS on of about 40 milliohms. Checking this data sheet. Yeah, you know, 40 milliohms or so, that sounds about right. And this one has slew eight control, although I'll say sometimes features aren't complete. It depends on the person who entered it in if they like were, you know, they filled in everything. So I always take the features as a grain of salt. Always check the data sheet. And the pinout, the package is the same, which means I can have a check if the pinout is the same. So these are both pretty cheap. So let's look at the V-shaped part first. So the V-shaped part, so here's what I always like to see. So the application circuit, see this? It's basically the same as this. It's very similar. There's the R1, there's the VN on off, R2. VN R1 on off. What's slew? Slew is how fast you want the current to go in. It's a current limiting thing. If something is slewed, it means it's gonna slowly ramp up. If you have high slew, it spikes up. There's times when you want it to react very fast. You want a lot of current and sometimes you want to reduce your inverse current because it could damage your components. Use slew in a sentence like that. What? You slew in a sentence. Like I want more slew because or like oh, too much slew. Last week we talked about op-amps and we actually wanted a high slew op-amp because we want it to react to volume changes very quickly. High slew. High slew. Okay, so for this one, you see the same pinout, two and three are V out, two and three are V out and one is the bottom of this. Looks like, yeah, another MOSFET. So yeah, this one and then there's a return. This shows the internal resistors but this looks actually almost identical. I mean, I will tell them, you know, you go and of course check that all the specifications match everything but this is very, very promising and there's 12,000 in stock and then for this one and notice that the part numbers are totally, sometimes it's like, oh, an NE555 or TI555 or an LM555, they all have the same part number. They have different prefixes. These have completely different part numbers and prefixes and that's not unusual. Don't, it's nice when they are but it doesn't necessarily mean it's bad if they're not. It just depends on. Yeah, everybody, we're all gonna have to adapt at least for a while. You gotta be flexible. Yeah, just because it's not the same part number doesn't mean you can't use it. In fact, that's gonna stop a lot of other people from either getting the parts they need or maybe even some changes to their design. You gotta be, you gotta stretch. Yeah, gotta do some flexing. This one also RDS on, you know, you see the specifications and then you can see down here again, the same thing. There's an input, two pins on the output. Pin six is, you know, you can connect to a capacitor out here. One is, this one has five. Yeah, one is from the bottom of this FET. Five is to the on-off gate and VIN is on pin four. So this is actually one of the times when like there's actually two looks like good options. Both have about 10,000 pieces of our stock in Digki right now. And they're like 30 cents, 20 cents, even cheaper. So, you know, if you can't get that TI part. Or if you're getting quoted like- Seven bucks. 10 bucks apart. Don't do it. Don't. Look, sometimes I agree. Sometimes there aren't any alternatives, but I'll say something. I've actually, other than very, very specific chips that are like, okay, yes, it's a one-off. Only this company makes this particular microcontroller in this package, and you need that exact microcontroller. No, you might not be able to get that. But analog and linear components and power components, there's probably something out there. There's probably something out there. You're not out of luck. There's gold at the end of the rainbow. So that's the great search. So check it out. Send us your great crises, your build material crises, and we'll help fix them. Where? All right, and then just a little slide now. Yes. Telescope mount terminology refer to slew rate, which is how much angular motion per second it can move. That's the same thing. This is actually, it's the same rotational motion per second, but the rotation is the, it's numerically in the imaginary plane, or the voltage plane. Like it's rotating, but it's not physical. That's in a voltage. Or current mode. Okay. Okay, great. That's our show for tonight. This is Descalade data. Thanks, everybody. All shows during the week. We have JP's product pick on Tuesday. 3D Hangouts on Wednesday. Show and tell. No one paid, we're gonna be hosting show and tell. We're gonna be doing Ask an Engineer. And then Thursday, we've got JP's workshop and Friday, deep dive with Scott. So full week ahead, tons of things and we'll be broadcasting. Ask an engineer from the Adafruit factory. Soon. Once again, very soon. The only reason we're not is because our shift overlaps with the team. Now we're all vaccinated and we're past our two weeks, but we're still setting a good example. So when we do video broadcasts, we do, we will take our masks off. So we wanna make sure that everyone's out. So it's just Lady Aida and I. And we have ventilation and all this stuff. We just wanna continue set a good example. And then for the teams that are still around, if they're fully vaccinated and they're after their two weeks or one month, we'll start to work with them. And then over time, it'll be as normal or whatever normal is that we define together going forward. So we'll see everybody soon as the show is during the week. Thanks for spending your Sunday with us. Thanks everybody. See you everybody. Bye. Next week.
