 and welcome to Desk Lady Aida. Hey everybody, welcome to Desk Lady Aida. Me, Lady Aida, at my desk, with me, Mr. Lady Aida, behind the mic and camera control, and more. We're gonna wrap it up a pretty hectic week. First week of New Year's, always very intense. I think it's been true for everybody. Yeah, you know those videos that you see every July 3rd, where they're like, oh yeah, look, someone accidentally lit off all the fireworks at once? Or it's like, oh look, it's a fireworks factory that blew up, and all the fireworks happened in five seconds? Yeah. It's kind of like that. So, just a little word to the wise. Pace yourself, everybody. These next few weeks in the United States of America, where we're at, and probably elsewhere, will be tough. There is no way around it. Not gonna candy coat it. Be good to each other, have empathy. I know we're out of spoons, but you just gotta do it, because we're almost through probably the worst, and it always gets a little bit worse before it gets better, so hang tight. We'll be here, you know we will be. Take it away, lady and I. Okay, I wanted to start with maybe showing off some of the floppy stuff, because I'm not gonna be doing engineering on the floppy stuff. Okay, do you want me to show the video from Friday? Yeah. Okay, let's kick it off. This is a one minute video. We also have a playlist with all nine videos, and then this one, so here is the latest one from Friday. Lady and I, what is this? This is my pet octopus. No, this is the wiring for the feather floppy stuff that I was working on last week. I'm getting back to it. This is the floppy drive, and this is one fill and it worked, but you can tell the wiring, it's a little bit wiry. So I really quickly sketch together a featherwing PCB that has all the pins labeled to make wiring a lot near. So I've got plugged in now into my feather M4, and this is the 34 pin interface, and I got this nice cable, which has even eight inch drive, and some five and a quarter maybe inch drive socket support. And then you can easily debug by plugging into the extra headers if I want to like, you know, watch the index pin or the data pins. And best part is, it still works. So now I can actually add floppy write support because I feel more confident that my wiring isn't gonna be flaky. So then you'll be able to fully duplicate floppy disks. Okay, that's where we're at. That's the latest. During over Christmas and New Year's, I had like seven, eight days in a row of like, you know, not doing emails as much. And so I had a lot more time to do floppy stuff every single day. And then, you know, as of the week kind of kicked off, got busy running Adafruit and making sure that the business is running and designing stuff for the business. And not that the floppy stuff isn't important too. I mean, it's electronics, we're gonna sell some floppy stuff, but we're gonna get back into it. You know, there's excitement and then it's like gonna slow down a little bit. Just to be straight up, the health and safety of our team is more important than this floppy project. But you know, Lady and I have been working on projects for decades and sometimes they take a while, but we're moving pretty fast. So what do you got? Okay, so let's go to the overheads. I'll show the stuff. Okay, so I've got that feather wing. So this is quite nice now because I can plug in this floppy cable. Got a real floppy cable. And one thing that's nice is this floppy cable also came with a five and a half inch floppy disk drive connector. And we got a five and a half inch floppy disk. Sorry, five and a quarter. Three and a half, five and a quarter inch floppy drive. This is a really nice drive in very good condition. It's got the lock and everything. This motor is pretty sweet and it's got this connector and they use an edge connector with like a little notch in it. There you go. So this is how you would connect. $5 to get to the entire cable but you'll only need the edge. Pretty much. So this is a pretty sweet disk drive. It's in really good condition. Nothing like lead solder to make sure that your solder joints are nice and shiny and uncorotated after decades. This was made, I think in 88. So this is good. So this should actually just work although I haven't actually, I just got this yesterday. I haven't had a shot to turn it on. I also have to get myself a 12-volt power supply hooked up together. I am a power jig for this because unlike the three and a half, the five and a quarters need both five and 12 volts and they really need that 12 volts for like this like enormous ass stepper motor. I mean, that's bonkers. This is 12 volts, a quarter amp and this is 33 ohms, whatever, do the math but it's also probably, it's probably like 12 volts, one amp and then five volts also, you know, half an amp or something for the control circuitry. So there you go. It's gonna be pretty cool. I'm excited to get this going this week. So that's the floppy stuff. So I'm glad I got that cable. Yeah. What else do you wanna show? We also have a question that I said that we would answer live on the air tonight in advance. Do you wanna do that one now or do you wanna- Oh yeah. Well, let me just show the last thing. Floppy flooper, PCB. This is for connecting to those USB floppy, those USB floppy disc adapters which are actually a laptop floppy drive connected to a PCB that does like mass storage over IBM 1.44 megabyte MFM format of floppies only. MFM format of floppies only. So, you know, by pulling out the little adapter and then you connect the FPC of the floppy drive to this, you can then convert it either to 34 pin because you want something to connect to 34 pin or a little breakout either way. So we'll see, I have to get the connector for this is on the way. I'll try it out and then I'll just verify that that laptop floppy drive works fine. And it's interesting because it's kind of hard to get three and a half inch floppy discs. Like you can get them, but they're not super, super available whereas a USB floppy drive is really available. And so I was like, well, what's inside of it? And yeah, it's just a laptop floppy disc. So if you can't get one of these large chunky type, just get the USB type, open it up, remove the controller or PCB and then you can do flux level readings if desired. So that's pretty cool. Okay, so it's on the floppy stuff. So yeah, if you want to ask, and just question a little bit of the QT and then- Yeah, one of the things I'm gonna start to do is we get a lot of questions. We usually answer them over email and everything or sometimes we'll do in the forums. And then sometimes we do them on video because like we're an open source company and like if we can light one candle, it makes another candle brighter and that candle can light another candle, another candle. And so I've just been asking folks like, hey, like can we ask you a question on air? So at least you get to see and hear it. So this is from Oz. It says that, I'll summarize the question they sent in. They're like, I'm about to maybe get an electronics company and move it to New York. And I said, okay, what do you want to know? And the question is, guess I'm curious about the benefits of being here, New York versus somewhere cheaper, finding space and what you wish you had known when you were starting. So Lady Aida, let's just start with the benefits of being in New York versus other places and something you wish you knew and I have some stuff too that I'll say. I think the benefits of being in New York is that it's a very large economy. There's a lot of people here and it's not hard to get people you want to move to New York to move to New York, if that makes sense. Like it can be challenging to convince people to move to somewhere in the middle of nowhere if that's where you're from. But a lot of people live in New York City or wanna live in New York City or wanna visit New York City. And so that's one really big benefit. Trade off is space is gonna be more expensive. You can go to Brooklyn and Queens and there's some industrial space. We're one of the last industrial spaces in Manhattan. There's just not that many. So you have to just be kind of smart and you have to be compact with spaces to think hard about how much space you need. I think, you know, there's nothing really that it's like, oh, I wish I knew when I'd started. I think it just takes a lot of work to run a business. But New York City is, even though it's not cheap, it's a lot of people really excited to see New York City businesses. There's a lot of folks who want to support you because you're a local business. And that's really nice. Okay. For me, one of the reasons that it's good to be in New York is time is money. And when we started Aderford, it was out of an apartment near where they were building, which is now the Freedom Tower, one block away FedEx, one block away UPS, one block away DHL, one block away 24-7 CVS, one block away Starbucks. There was JNR, you could get anything which is like- One block away Radio Shack. So for two, you know, quote founders, we were able to get access to everything that normally people would have to hop in a car at spin hours. Also, we had a lot of college age employees that were working part-time with us. We paid great, they really liked the job, they liked the flexibility. And so we were always able to get a huge talent pool. If you watch the news, talent pool is tough. We pay more, we give more, we do more, but we also get more. And so I think that's one of the benefits is you have access to so much so instantly. None of our team members drive cars, they're taking public transportation, they're able to do other things. There's eco-friendly versions of companies and one of the things that we say is public transportation. New York is public transportation. Yeah, we don't have to pay for parking. There's no parking lots. It's like, okay, space is more expensive, but I'm not renting a parking lot because nobody drives in really. Every subway comes to Adafruit, no matter where we've been. So... And there's great food. Yeah. I remember when I worked in Minneapolis, it was like, okay, we're gonna go to the TGI Fridays or the Chili's. And it's like, there's so many good independent restaurants and good eateries. I mean, there's chains if you wanna go to chains, but if you just want an excellent burrito or a great Cuban sandwich or a Vietnamese fa in the middle of the day, there's one to block away. Here's the other thing. So what? Come to New York, maybe you won't make it, but at least you get to say, I tried. And I think that's the thing that matters is everyone should have a New York story. Everyone is running away from or running to something in New York. You'll meet people that you'll know for the rest of your life. You might meet the person that you're gonna spend the rest of your life with. New York is a good place. Now, as far as things we wish we knew, I always think about that. And when we were starting, Lamor would ask me, hey, do you think everything's gonna be okay? And I'm like, oh yeah, one day, we're only shipping 10 orders a day now, but pretty soon it'll be 10,000 and sometimes a day or a week. And I think one of the things is nothing happens instantly, at least nothing good. So the thing I wish I knew was it's okay if things take a few years instead of a few days. And I would just wanna hear that from the future again. Even though I knew it, that's the thing I wish it was like, look, no matter what you think or do, things just take a little bit of time. And that's why we built a solid business. So I was able to take care of people and what I think folks are gonna say was one of the hardest time periods in all of our lives, which is now. So anyways, that's what I would say. Okay, great. All right. So I'm gonna go to the QPIs that I designed this week. Yeah. Can I do one note, one more note? Adafruit.com slash CircuitPython2020. We're crazy. We like to hear from our community. We like to hear from everybody. Tell us what you want in CircuitPython. Just go to Adafruit.com slash CircuitPython20202 and let us know. It's also on Adafruit.com. There's a link right there, right hand side, little box at the same graphic. Please, please, please let us know because we'll actually do it. Okay, Lady, let's do some stuff. So what's up first? So I designed a bunch of QPIs and I also made little diagrams for them, which means I was working on pretty pins. I took a little screenshot showing the process of taking data sheets, information and putting it into a spreadsheet. As I do that, I kind of double check it. And this is what I used to generate the pin diagrams. Next up, I made an NRI-52-840 Stem IQT. This is one I didn't finish routing because actually, I got a little bit G-Pay I routed, but because of the weird chip style, it's like a dual row QFN, it's just gonna take a lot longer for me to route it. I know I'll be able to get it to fit, but it's just kind of like, it's kind of not fun. So I put that aside. So the next one I did is the ESP32 S3. And this one I did next because the S2, which is in the store now, and actually we're gonna make the UFL version next, was pretty easy to do, it was a dual layer, but it was also like a really good chip to do because it's got Wi-Fi and it has USB and it's got enough pins and it's great for circuit Python or Arduino. The S3. Oh, this is the back of the same one, right? Yeah, but the front looks the same. Oh, you want me to keep it? Yeah. The S3 is almost identical, it has a dual core, so it's more powerful it has. It does have a DAC and it moves around a bunch of pins and I think there's some peripheral changes. I know this has also got like a, the S3 has like another like low power core inside of it or something. Basically the S3 is a dual core, which is really nice because it means that you can have all your Wi-Fi stuff handled on one core and then you have plenty of processor speed left over and the front looks the same as the S2, which is why I'm like, you know, not much to look at. You have the boot button, the reset button antenna. The SWQT port has two different pins, so it's got 13 pins total, but other than that, it's pretty much the same as the S2, it's just, I just shuffled a couple pins around because the GPIO moved down and something, something, something, but so just watch out if you're moving something from the S2 to the S3 chip. The module is almost the same, it fits the same pin out, but the chip is not quite the same pin out. Okay, and those last. Then I was like, well, you know, like if I'm doing the S3, why not do the ESP32? And this wasn't possible until there was the Pico version of the ESP32, which is confusing because it was the RP2040 Pico, but the ESP32 Pico is a 7 by 7 millimeter 56 pin QFN chip that has PSRAM and flash in it. So this is a four megabyte flash, two megabyte PSRAM ESP32, but like for folks who use the ESP32 or like have projects like this is going to just work, you know what I mean? Like I like the S2 and I think the S3 is going to be very popular, but there was just thousands and thousands of projects that use the original ESP32 like, like usually tens of thousands of projects and it has Bluetooth classic. So I, you know, I rounded out this design, this was a little bit hairy. I started to have to like for the S2 and the S3, I didn't use the inner layers. They like they were pure ground and power planes, but the ESP32, because it has that USB serial converter chip required and they don't get any smaller than the CP20102. That is the smallest size that you can get for a USB serial converter that has the DTR and RTS pin because you need both to do the auto reset. That said, everything else is integrated like the crystal is integrated in the ESP32. I put a pie network on the antenna, but it technically is already in there. Kind of like everything that pull ups, every only kind of extra stuff that you'd expect. So nothing, you know, I never, I kind of forgot about the ESP32 is you, it looks like it has a lot of GPIO, but it actually doesn't. A lot of the pins are taken by the QSPY flash and the PSRAM and a lot of them are inputs only because they're near the antenna. And so, you know, and I wanted to get the high speed SPI pins onto the SPI port that clock mostly MISO pins. So they kind of like, you know, after I finished it, I was like, oh shoot, I forgot to do that. I had to reroute the whole thing. But I think there's a couple of projects I wanted to do where, you know, like it could make like the tiniest little like Sega Genesis emulator or something. And you really do need to have the high speed SPI for that. You want to be able to drive that TFT at 80 megahertz using the high speed SPI peripheral. So this was probably gonna be the smallest ESP32, like full all, you know, altogether, but that actually worked for that in the additional hardware. And even got the battery and ground pads at the top so you can run off a battery. And the Neopixels driven off of a, the power is driven off of a pin. So I think that this should be able to actually go very low power too. So it'll be interesting to see. So I'm gonna order this PCB and to prototype it, to check my prototype, I made this pinout diagram to kind of help me visualize all the ADCs and the high speed SPI and the touch pins and, you know, making sure all of them are input and outputs, but I got all 13 GPIO out there. So that's, that was a kind of nice one. All right, well, we have a video message because there's a lot of folks asking about risk they wanna know, is it good? And here's the answer. Risk architecture is gonna change everything. Yeah, risk is good. Yeah. I'm Angelina Joy. No, not really. Now, so I wear the dress in this household. That's right, we both wear the dress as we go. We go on the roof to our pool date. So having done all the other ESP32s, I was like, well, the last is the C3. And what's interesting is I actually looked at designing a C3 feather a few weeks ago and I decided, well, maybe a few months ago, I decided not to because the C3 has like very, very few GPIO pins, like eight. That really doesn't have a lot of GPIO pins. And so as a feather, it'd be kind of like, it's sort of like the ESP8266. It's like, I was like, I don't know if people really want something that is missing so many IO pins. Although I might change my plans on that anyway. So the C3, there's a version that has flash built in. There isn't a version with PSRM at this time, but it's small. It has a built in USB serial converter. It does not have native USB. So it's not gonna get supported by Circuit Python. Really, I mean, like maybe, but like not super well because it can't show up as a disk drive or advocate keyboard or mouse. But it is a risk five chip and it's kind of like our first risk five. And if you're gonna do risk five, having one that has Wi-Fi built in is nice. And ironically, I thought this was gonna be a really easy route because it's like the chip is pretty small. You don't need a USB serial converter. You don't need a lot of stuff with it. You know, it's pretty simple, but actually because the pins are so restricted, I actually, it was actually tougher than expected. I ended up having to put a lot of stuff on the middle layers because they're just, it's not like, you know, one of the nice things if you have a chip with a lot of pins, you have a lot of flexibility about which goes where because you can just swap pins around until you get a nice, you know, for all the, like the iceberg C pins, it doesn't matter what you use. So you just pick whatever the closest easiest route. But with this, a lot of the pins were really restricted because there's not a lot of ADCs. And then some of the pins have special functions and then like a whole slew of them are used for the internal flash. So, you know, I had to use every single pin and so actually routing was a little tougher than expected. So it's not even clear, it's not clear that it has a high speed SPI peripheral, like some of them are marked HSPI, but I'm almost positive that those are used internally for that internal flash. So, you know, the ADCs are fixed and then I squirt C is the special and the UART pins are on the UART pins. So that's that. Okay. Well, we have a couple of questions and I'll just go to this because it covers a few things. Quick question. What's the power draw difference between the QDPI, ESP32, S2 and S3 is one more power efficient. Just curious for wearable projects. The ESP32, I believe is the lowest power because I believe you can go down to 30 micro ounce. Now I know I've looked at the S2 because I've had to do low power stuff for the S2, like for the MagTag. The S2 does not get lower than like 60 or 70 or 80 micro ounce. I've never been able to get it below that. I believe the ESP32 in deep sleep can go lower. I think it can go like 20 or 30. That said, like that's pretty low. Like both are extremely low. Like once you get under 100 micro amps, like, you know, that's a very, like yourself discharge of your lithium polymer battery is greater than 0.1 milliamps. Right. Great question, Michael. And then SS220 Astro has the question that I was hoping someone would ask because the next answer is a visual answer. So SS220 Astro says, are you planning a feather-like ecosystem for QDPIs? Yeah, we're coming up with a name. Right now we're calling them BFFs. But I'll tell you some of the other names in a second. So Lady, what's this? And will we have an ecosystem for all of the things, accessories that go on to a QDPI? Yeah, so like, you know, we designed the trinket a long, long time ago. And the trinket I really liked but it was actually a little bit too small. I mean, I'm still gonna sell the trinkets but I don't want to design. The reason I'm able to make all these different QDPIs is because it's just wide enough that you can get more chips to fit, whereas the trinket actually was just mechanically too small and didn't have as many pins. And so like, I felt like this, you know, the shower layout from Seed is actually a better layout. So when I saw it, I was like, oh yeah, that is kind of cute. There's something kind of nice about it. It's kind of square-ish, fits in a breadboard. It doesn't have mounting holes, but it's so small. Maybe you don't need any. You can use the pins for mounting holes. So I saw GeekMom posted on Twitter this really cool ESP32C3 which had neopixels on the back. And I was like, oh, that's a good idea. Like, you know, I could have a PCB that kind of fits on the back of the QDPI, not in the front, because the front has got the buttons and USB and stuff in the antenna, but it can fit on the back and it would have like a little five-by-five neopixel rigs, a little bit like a micro bit, right? And so I did a quick layout and this would sandwich onto the back, right? And so you would probably use little headers, maybe little headers and spacers to make a little sandwich, like a little skinny sandwich, but then you could add functionality. So I designed a couple of these, again, designing a lithium polymer backpack one because I had like the protrinket backpack and this is gonna be a little similar. But again, it fits on the back, not on the front. So not good for projects that are on a breadboard, could be good for like, if you wanna make little charms, like little projects that aren't breadboard friendly, but that like, you know, are standalone. So I think I'm gonna design a couple of those. Yeah, so here's the thing and we open this up to everyone always because my opinion is a way to get a good idea is to get lots of ideas. So folks on Twitter and other places have come up with some ideas because we were like, well maybe we'll call them BFFs for now, sandwiches with slices, booty, chicklets, and then the current popular one is mullet and mullets. And I'll tell you why we can't do it. It is fun to say, business in the front, party in the back, love it. But sometimes, you know, people have made fun of each other because of haircuts and stuff like that. And also generally mullets, you know, do tabs. So we're trying to find something that's okay, codename mullet is here. Don't worry about that. We're calling them mullets internally, fine. I won't stop you, but I don't think I don't think I can have the official name be that. Yeah, but BFF right now is what we're going for. So QDPI has a BFF, you know, we'll see. But if anyone has some names, chicklets has a weird trademark history. Stay away from that one. And then sandwiches and slices. And there's a bunch of other ones that folks are talking about. But thanks for thinking of these folks. Really appreciate it. But we're not gonna call it a shield. I'm not gonna call it Wayne. I'm not gonna call it a hat. Not gonna call it Capes. But I think right now BFF is at least where we can bring the most people together. And that's what we try to do with a lot of stuff we do. Okay. So that's gonna lead into The Great Search. Let's do The Great Search. The Great Search brought to you by Digikey and Adafruit every single week. Lady, user, power of engineering, to find stuff online at digikey.com. And guess what? It's hard to find stuff. We've been doing this before there was a part shortage we'll be doing this after Lady Adafruit is The Great Search of the Week. This week. Okay. This week I'm looking for a new part that I'm gonna put on my ESP32 QDPI. Do you mind clicking on the Pico board? I can show in the back of it. Left, left, left, left, left, left. This one? Left one more. This one? Bang. Okay. So the ESP32 is a kind of interesting chip because it doesn't have native USB. So you've gotta add a USB serial converter. And that's the second chip. The one in that kind of the middle top there. The ESP32 is the thing on the bottom. So we've got a CP2102 and we covered the CP2102 as a USB serial converter, like a low cost, small USB serial converter. And that's all good. But there's another little thing. Not only do you need the USB serial for RX and TX data, but by doing this kind of funky trick with two NPN transistors, you can use the pulses from the RTS and DTR lines on the USB serial converter to reset the ESP32 into bootloader mode. And this is similar to, if you have an Arduino, the Arduino also used RTS or DTR to toggle the reset line to kind of auto reset the board from USB serial converters. For the ESP32, they didn't connect the DTR and RTS directly. Instead, they have this little transistor, like flippy floppy thing going on there, which I once analyzed and then I totally forgot how it works. So let's go to the computer and I will pop up the schematic and I'll show you the part. So this is what it looks like. You connect, there's IO0 is the bootloader pin and reset is the reset pin for the chip. And then RTS and DTR, when they do a little toggle, they will lower the IO0 pin, which tells it to go to bootloader mode on reset. And then it quickly toggles the reset pin to set it to reset. It comes out of reset, IO0 is still low. It knows it should go into bootloader mode. So the only thing is I need to get a dual NPN. Now I've got N-channel FETs here, but you can't use N-channel FETs. I've never actually tried it, but like every schematic from expressive users to NPNs. So I'm gonna show you me need NPN. That said, I do like the dual BSS that we use on a lot of our boards. It's this part here and it's nice and small. So these are 0402 resistors. This is a TSOP6, also known as a SOP363. It's finer pitched than a SOP236, which is a SOP23 is, I'll show you. So this is a SOP23 size. So it's significantly larger. I'll use a SOP23 for a power supply, but for something that's not using a lot of power, like this dual FET thing, a SOP363 is perfectly fine. And you actually can solder them by hand. Like they're fine-pitched, but they're 0.5 millimeter. So they're not gonna kill ya. You can hand solder them. We use them by like the hundreds of thousands. Every static UT board, we include a dual FET to do the level shifting for I squared C. And so we stock 1000, 1000 of them. But again, those are BSS138N channel FETs. This time we want dual NPNs. So let's go to Digikey. First up I wanna mention, so this is the dual FET that we use. BSS138BKS, we have a quarter million stock because we actually go through like 10,000 a day easily. Because there's like two or three on like almost every single board that we make. So there's a very small part and this is the part. I actually couldn't remember the name of the package. So what I did was like, if I want something in the same package, I'll actually look up what Digikey calls the package and then it'll just make it a little easier for me to find the part. So this is called, this has multiple names and that's not unusual. Sometimes when they get these small chips, they have different names. So this is called a 60SOP or SC88 or ASAP363. So good to know. Anyway, so what we want is a dual NPN. Pardon me. There's a couple NPNs. Just be careful, because I actually accidentally went to single. Like I went to single first when I started searching. You can't, you have to go to arrays. And NPNs come in a couple different configurations. So it's not a big deal, just watch out for it. Sometimes they do you a favor by connecting stuff inside, but we want two completely separate NPN transistors. And again, for most of our ESP32 boards, we just have two SOT23s, but we just don't have any space on this board. It's so small, I have to go with the SOT363. So let's go with in stock active and then let's look at that package. So again, I like the package that I've got the BSS138 in, which is a 60SOP SC88363. There's probably smaller, but this is pretty small. I think like a UDFN will be smaller, but I like things with pads for stuff this small. Okay, so let's apply. Because I picked something with six pads, I sort of solved one problem, but if you look at the configuration, you can get common emitter. Common emitter means the emitters to kek together. This is really good for differential measurements or amplifiers. There's quad, of course, and then there's matched pair and non-matched. Matched pair, it means that they're guaranteed to be with a certain percentage of the same VBE, like whatever, like the amount of current that they're gonna pass and the voltage offset you're gonna get, like they're gonna act very similar. Again, that makes it better for differential signal measurements. In this case, it doesn't matter, because again, we're using them totally separate, but also we don't want common emitter. So I don't mind looking for matched pair, but usually I have to pay a little bit more for matched pairs. If you do synthesizers, you're gonna constantly be doing matched pair stuff, but I'm not doing synthesizers, I'm doing a cutie pie, so that's cool. Okay, back to this. Once I select that, yeah, there's only matched pair and non-matched pair, which I don't care about. And then when I go down here, I started by price just to see like, okay, well, how much am I gonna pay for these? And one thing I noticed is that the ones that are the least expensive, like these Pum-X2s from Nixperia, they have a min quantity and there's no way to not select. I don't know that there's a way to select something that doesn't have a min quantity, but if you click here, you can only buy this by the real. Like if I try to buy 300, it's gonna say no. So that's not like a bad thing. Like I might use these, but if I'm gonna get samples, which is what I'm doing right now, I wanna get something where I don't have to purchase a large quantity. So for example, like this has a minimum quantity of like 4,000 and I don't wanna buy 4,000. So what I did is when I got to these two on semis, this BC-84-7, these are the ones where I saw like, oh, they have plenty in stock. There's two versions. There's one from Panjit and there's one from, there's a couple from Panjit and one from OnSemi. And these have a minimum quantity of only one. So, you know, it's tough because the other ones are much less expensive, although it's a minimum quantity and maybe at the minimum quantity, or the quantity I need, it'll be about the same. But I'm getting only samples right now. Anyways, so I order the sample. Samples wanna get the PCBs on order. So by the time the PCBs make it to me, I've got all the components. But these are in stock and they look just fine. So I'm gonna pick these up, I'm going to try them out. And nothing really beats just soldering them into a circuit with an ESP32 and just checking that it works. But I'm pretty confident it will. Like the ESP32 Reset Circuit is like very well tested and tried. So even though I've never tried this particular transistor, you know, they have a, the voltage limits are reasonable. The current collector, the current, max current to the collector is reasonable. The DC gain is reasonable. Everything, this is a very jelly bean part. So no reason why it won't work. So this is gonna pick up 50 of these and get ready for when my ESP32 QDPI arrives. This is the one part that I don't already have stocked. And that's a great search. All right, I guess I'm breaking news. What's breaking news? Well, first off, I saw Geekmom in the chat. Thanks Geekmom for stopping by and coming up with some fun names and more. And publishing your projects. You know, we love seeing yourself, thank you. So someone came up with a name in the chat. This was from Tackle the World Sprinkles. That's kind of nice. Sprinkles, okay. Sprinkles. Because QDPI seems to have, you know, like, oh, that's cute. It's like a cupcake. It's like a little cute thing. Like maybe you put sprinkles on top. You put sprinkles on top. Okay. Yeah. But, you know, nice, friendly terminology, sprinkles. Yeah, so we'll see. BFF fits on the board. These are tiny boards. Yeah, these are small. I've got a couple more. I'll be posting over the week. I designed a couple more and, you know, I have some ideas for them. But I actually have a project. What's funny is what kind of prompted the QDPI ESP32 is I needed a project with a Bluetooth classic chip. And then I realized, like, we, you know, I don't have anything really tiny that does Bluetooth classic. And so I was like, ah, ESP32 is one of those few chips that can do Bluetooth 2. You know, it's dead, but it's kind of not dead. A lot of things still use Bluetooth classic a lot. All right, everybody, that's the show for tonight. Thank you so much for joining us and being part of this adventure. We're gonna keep doing this thing and we're not gonna stop. And if we can do it, you can. If we can make it in New York, so can you. If you can make it here, you can make it anywhere. We'll see everybody during the week we have our entire set of shows that we do every single week. Tuesday, J.P., Wednesday, you know, Pedro. Also, Lady A and I would show and tell and then ask an engineer. We might have to move stuff around. Who knows, these weeks are trying, just as someone who helps run a company with Lady Aida. This is as hard as when COVID first started in mid-March. The gymnastics we do on a daily basis. We take really good care of our team, so we just have to do a lot. You know, sometimes people, this is devastating news. One of their kids tests positive and they have to do a bunch of stuff and they just need someone to talk to them on the phone. And that's my job. And I can help them through it. And so sometimes we move shows around stuff. It's not because we don't want to do it, just sometimes we just run out of time. And more so, we appreciate the support and patience that you have on Thursday, another J.P. show, and then Friday, Deep Dive with Scott. We'll keep doing this stuff. Thank you everyone so much for supporting us. Please pick up something in our store. It helps a lot. It does, that goes straight into paying everybody. Yeah, the money goes directly from you to pay our team and the bills and the inventory. And that's it. That's all we do. All right, so we'll see everybody next week. Thank you so much. Thanks everybody.
