 Hey everybody and welcome to Ask Engineer. It's me, Lady Aida, the engineer with me, Mr. Lady Aida on camera control. Thank you. We're both right golfed today. We're broadcasting live from downtown Manhattan. That's where we have the 8 foot headquarters. We do all of our kidding and shipping and packaging and coding and we do assembly. We do all sorts of stuff there but right now we're gonna hang out with you guys for like about an hour. Me and Mr. Lady Aida and we had a full packed show of goodies to show you. We gotta leave a little early but the show goes on so we're just gonna condense the show for all the important things that you know and love and want to watch each week. It's gonna be like a neutron ball of like Aida fruit. Yeah. Okay tell us about that show. On tonight's show The Code of Spring 8, 10% off in the Aida food store all the way up to 11.59 p.m. Use it in sport and open source hardware, company, manufacturing, electronics in New York City, USA. Talk about some of our live shows, got a JP's product pick of the week highlight, some main New York City factory footage, a 3D printing speed up. We've got Eye on MPI. This week is Rich Tech brought to you by Digikey. Thank you Digikey. We got some top secret previews of some new trinkets, some new products. We can answer your questions over on Discord. We can join like all 33,000 of us, aidafruit.it slash discord, discord.gd slash aidafruit. We're gonna talk about some free stuff, all the things you can get in addition to the discount code, all that and more on Ask Engineer. Yay. Yeah, okay. So don't forget Code Springy and what do we get? Springy into Spring. Okay. Springy, what do they get when they start putting stuff in the cart? Yes, when you order from aidafruit.com, we give you free stuff. Like if you order $99 or more, it'll give you this beautiful gold and black coaster with the aidafruit logo and some little rubber bumpers. It's great for putting your hot or cold drink on it and it will keep your desk nice and clean. And we're still doing our $149 or more giveaway for the KB2040. It's a pro micro pinout compatible microcontroller featuring the Raspberry Pi RP 2040 chip with flash memory buttons and NeoPixel, USB-C and cast-related pads. So it's a great little microcontroller board with a nice powerful chip, a good upgrade to the pro micro. $199 or more free UPS ground shipping in the continental United States. And last but not least, for $299 or more orders, we give you a free Circuit Playground Express. It's round and colorful and has sensors and buttons and it works with Arduino, Code.org, CS Discoveries, MakeCode, Circuit Python, and many other languages. It's a great way to get started with programming or electronics without any other tools. Okay. We did a bunch of live shows. We just got off the air. Do check out all the places we post our videos, all the places such as YouTube, Twitch, Facebook, Instagram, Reds, you name it. Yeah. Thank you JP for doing show and tell. On Sundays, we do from the desk of Lady Aida in the great search. Watch that there too. And on Tuesdays, we do JP's product pick of the week and we have a highlight of this week. Take away JP. It is the SHT 41 Temperature and Humidity Trinky. It has a quick, easy monitoring solution. And you can see here, this just slides right in. And that's a thick enough board that it actually stays in there quite nicely. Here you can see every two seconds, I have it logging the temperature in both Celsius and Fahrenheit. So it's about 78 degrees in here right now. And humidity is at about 29%. I can probably skew that a bit either by just touching the sensor that'll probably warm it up a bit. Oh, it's cooling it. I'm cooler than the air. You can see the humidity jumped up there just because of some perspiration on my finger, or if I blow on it. So if we give it a little warm, hot breath there, we got it up to 83 degrees and about 80% humidity. The SHT 41 Temperature and Humidity Trinky. Okay, and don't forget on Thursday, you can watch JP's workshop on Friday, deep dive with Scott. With Scott, yeah, Tim. Or 5pm Eastern. And Scott's not there. It's deep dive with Tim, but usually it's got now. So do tune in on Fridays. Okay, let's do some Python on hardware time. There's a couple things you want to talk about this week. Yeah. You wanted to talk about, we have 903 released. Do check out the latest. And then there is expressive chip news. Well, sign up if you want to get notified when we have this ESP32C6 feather. It's still in prototype phase. That's why it's green. But you know, one day it'll not be green. It'll be black and how you know it's released. And then you'll get notified when it's in stock. Another thing that I thought was kind of cool is we saw a preview like almost a year ago about the ESP32P4, which is like a very powerful processor. You want to scroll down a little bit? Yeah. So this is like a like it's so essentially it doesn't have Wi-Fi, but it does have Wi-Fi. It wasn't clear at the time. So it's Wi-Fi, but it has like dual core 400 megahertz processors. I don't know if it's in 10th silica or risk five. It's got like CSI, DSI support, HDMI, just a lot of display, very serious displays, which they've been sort of practicing a little bit with the S3. So the P4 is really cool, very big too. 32K of built-in SRAM and of course PSRAM can be added. There's 16 kilobytes of ROM. I think that's just to run it. Oh yeah, they go up to 64 megabytes of PSRAM built in 768 kilobytes of SRAM and then through 2 kilobytes of low power SRAM and they're really good at low power stuff, a few DSP, but yeah basically display stuff is where it seems to be. I've built in decoders and stuff. So yeah, obviously we all are interested in the chip when it comes out. We'd love to answer goodbye on support. Yeah, I got a question for you. So they have independent in deep sleep. So when a chip maker says something like this, how would they handle that when they say independent? Like what are they doing? That's a good question. What are they doing to say independent? Is it another chip that does it? It's like waking up stuff, watch dog as I say. They could have a low power chip like a risk five core. They've done in a couple chips so far. They've had the main core and then a very, very low power risk five core. So there could be some sub-processor that is like in deep sleep of the main processor. It is doing little tasks like checking for a voltage or communicating or R2-T or checking for pins and stuff. That's what that means. Yeah, that'd be interesting. As someone, Todd mentioned the chat that you know they're keeping the ESP32 brand in which they don't need to, but like everyone knows what that is. So yeah, I mean like it you know yeah it's a little confusing if people say ESP32 it's like well do you mean the classic or do you mean the S2 or the S3? But you know it is a very strong brand and it probably is something to that name that means something. It could be that's the tends to look like a 32-bit family. Yeah, I don't know. Yeah, I mean like they do have the ESP8225. Well for tech naming there's Windows, MTO in the chat says .NET. There's a lot of terms. I remember I did work with Sony a long time ago. They had memory stick, memory stick dual pro plus, memory stick dual pro extreme. Yeah, it's challenging because on one hand it's like you know you want to lean on a good name, on the other hand it could be confusing. But you know like the AVR series I got now had a you know still making AVRs and they've changed quite a bit. So I'm kind of curious about how they're going to do independent deep sleep like is another chip. What is that thing? Like what is it? Yeah, the deep sleep is very interesting, very innovative on that. Yeah. Okay, so what else did you want to talk about? The other thing that's kind of cool is Todd bought these cool mini videos about using, oh go click on the mastodon link. So these neat videos, I don't know what's going to happen. You can play the video. So we added this thing called bitmap filter for the camera and then like I kind of like never got to the projects I wanted to do with it. But I like that he's like revitalizing this thing which allows you to, it basically allows you to set up a kernel for a convolution filter that you can then apply to a bitmap. And I believe we actually did three by three by three. So like true RGB cubic filter. So you could actually like have different channels affect other channels. And others would be kind of cool because you could like maybe do like some photography filters on it. But like I said, I never got to it. So it's kind of interesting to see that he's like, oh, like I'm doing like process, like I'm kind of processing like art. It'd be cool to have pie processing be like, you know, a Python version of processing for making these kind of cool, funky filters. That's cool. And yeah, thanks Jebler for bitmap filter. Yes. Is there anything else you want to talk about? That's it. I think that's a lot. Yeah. There's more, I mean the news. Tons, yeah, tons and special thanks to Ann, our editor-in-chief for the newsletter. We deliver this every single week to your inbox. And you can get that at AdafruitDaily.com. We keep it separate from your store account because we do not spam. Okay. Some open source hardware news. First up, we're a sponsor of the open hardware summit. They posted up the sponsor list and more. And do you know how many open source hardware contributions we have? At the time it was 740, but I think it's actually like 716 or something like that. Every 745 or something. Yeah, it's a lot more. And so I think like right now we're, well, I know we're the top contributor, but then people make open source hardware based off our stuff too. So there's, it's an ecosystem, it's good. So we're really pleased to see the certifications going. You're doing hardware and you just want to send the signal out that you really did open source hardware. There is a certification process. You can do it super easy. We do it. And for the folks that are going to the summit, have fun. Yeah, I think it's in Canada. Yeah. So next up we have our Adafruit Learning System Guides. What's on the big board this week? Speaking of open source hardware. Okay. We actually had a lot of updates. A lot of these like Raspberry Pi updates. So we've been doing a lot of testing to make sure that all our stuff works with the latest version of Bookworm and the Raspberry Pi 5. You'll see a lot of updated guides. Liz also did a new guide for the TCRT photo reflective interrupt sensor. Thanks Liz. It's a simple sensor, but still need to guide. And we also have a guide for the LTC 4316 address translator. And I think last week we had the watch winder and the IOT batteries. So a lot of people working on projects, you know, they're coming a little burst. You'll see a couple of projects get published in the next week or two. Okay. Cool. Let's take a quick break and do some factory footage. All right. Next up. So for 3D printing this week, we just have a speed up and then we're going to roll right into ION NPI. So now Pedro, take it away. Okay. Don't forget the code is springy. Let's do some. ION NPI. Part 2 by DigiKey. This week is Rich Tech, your power partner. Yeah, partner. Hey, Data, what is the ION NPI, the new product introduction of the week this week? Okay. To no one's surprise, it's a power chip from Rich Tech. They're really good at making power chips. So this week it's the RT-6160A. It's just like this. It's a very small chip with, you know, BGA. Mounting is designed to be very small, but don't let the size fool you. This is a very powerful chip. This is a very interesting and very useful, kind of all-in-one power supply and management chip that you could use for, especially something wearable that uses batteries. It's a three-amp output buck boost converter, which is like a massive amount of current, or sorry, the switch I think is probably three amps, which means still you can get, you know, an amp of load or more. And it's a buck boost, which means it runs from as little as 2.2 to 5.5 volts. And then the output can be kind of anywhere between two and five volts. Also, say like 2.83, 3.3, 3.5 volts are all valid. And you can use the I-squared C interface. It has to configure the voltage output. So you can dynamically change it. You don't have to use resistors to fix the voltage. If you want, you could start running your, you know, code at 3.3 volts, and then you can drop it down to 2.8 later. Yeah, sorry, it does have up to three amps of output current, especially in buck mode. It's going to do great for that boost mode. It's 2.5 amps max, but still a huge amount of current. And an amazingly low quiescent current of one microamp non-switching, and I think another one or two, like two microamps total typical quiescent current, which is like unbelievably low, even most LDOs don't go really below like 10 microamps. So, you know, amazingly low quiescent current, high current and high efficiency output, and it's configurable over I-squared C. So it kind of does everything you need in the power supply chip. You know, a lot of people ask me like, when would you use a buck boost converter versus an LDO? And I use LDOs all the time. In particular, I use the RT9080 a lot, which I'll show in a second, which is a LDO from RichTech. And, you know, the LDO stands for low dropout because basically have the input on the left, and they have this power MOSFET that you kind of turn on and off, you know, with this op amp circuit in the middle. And you basically, you know, tweak the amount of voltage on the FET until the output is the voltage you want. So, VN always has to be above Vout, so you can have 5 volts in, and you could have 3.3 volts out. But then all that current in between is burned off as heat. Like that 1.7 volt difference, you have to dissipate that out. And so it's good for like, you know, low current, low efficiency, because you maybe don't care, you're running on a battery, and you don't, you know, you don't want to have the space with the expensive buck boost converter. As long as the VN is pretty close to the Vout, maybe, you know, the dropout is so minimal, maybe it's still within 90% efficiency and low noise. Like I mentioned, that I really like the RT9080. This is like, I'll go to LDO for our low cost boards where we don't have a buck or a boost converter. And what's nice about this board is, it's got, again, very low quiescent current, like 5 microamps or less, which means, on this itsy-bitsy ESP32 here, if you look on the left, you can see in deep sleep mode, the ESP32 is, you know, maybe 5 to 7 microamps, and the LDO is 3 microamps. It's just unbelievably low current, compared to like other chips, which we use like the AP2112, which has like 50 microamps of current, which just makes a big difference. It's like, it basically means you get 5 times as much runtime in deep sleep as you would. So a lot of people, when they're designing wearable or portable projects, they're going to be powering stuff off of a, oh, sorry, I can just move to the, this is a lot. Like a Xanax. Yeah, sorry. I just want to make sure we don't, we don't skip ahead. They're usually running off of a lithium polymer battery. So the lithium polymer battery, they're called 3.7 volts, but really, you know, they have a nominal of 3.7, but they start at 4.2. It depends a little bit on the temperature, as well, and the drainage. So here this is, that see here is the drain rate. So assuming you have a low drain rate, 0.2 of, you know, if it's a 1,000 milliamp hour, that means it's your 0.2, times the milliamp hour in milliamps is the rate. So if you're drawing like 200 or 100 milliamps or less on average, you start at 4.2, which is well above 3.3 volts where you normally use it. But then as you kind of drain more current, especially high current, the voltage droops quite quickly, and then you very fast get close to 3.3 volts or even below. As you see, even, you know, especially if you're doing spikes of current because you have like a radio or you have a motor, you can quickly have the voltage of the battery dip below your 3.3 volts nominal voltage and it'll go down to 3.1 or 3, but there's still plenty of capacity and current inside. So you want to use something like a buck boost. So when the voltage of the battery is above 3.3 volts, you'll buck it down and use an efficient buck converter so you're not losing any of that dropout voltage. And then if it's below 3.3, you'll boost it up. And a really nice design, as you see here, it's all inclusive. So you'll need one inductor. It's a generic example. You need one inductor, input capacitance, output capacitance, and then a resistor divider to set the output voltage. These tend to be more expensive than just a buck or a boost. And they, you know, oftentimes have a little bit more complexity. But what I really like about the RT-6160 is how simple it is. Like this application, you know, usage schematic, it's like you really just need an inductor and it needs to be a big inductor. You need input capacitance, output capacitance. And you don't need a resistor divider because the default output is 3.3 volts. And then you have, you know, a couple GPIO lines for the I squared C configuration enable and signal. The signal is what determines that I'll show you later. There's two voltages you can switch between. And of course, enable takes it into low power mode. So not a lot of pins, not like there's no like strapping capacitors and like feed forward, and then compare it to the TPS series. The quiescent current here is two to five microamps compared to 15 to 25. So for deep sleep, it's going to make a really big difference. Okay. And then it is a BGA. It's a WLCSP. It's very small. It's designed for like, obviously like very tiny circuits. I can definitely see it being used for audio circuits where sometimes you are going to, like I said, motors, radios, where you sometimes need to connect over Wi-Fi, you have a burst of 500 milliamps or one amp of current. But otherwise it's going to be very low current sipping and you want to maximize that battery because by using a buck boost with this low quiescent, and I'll show you the configurable battery, you can really like get that last five, 10% of battery life out without harming the battery but keeping your circuitry running. One thing just to note is, you know, it's not a wide range input output. It is, you know, basically two to five volts in, two to five volts out. The Apple Curtage 3 Amp is just a lot. Just, you know, make sure that your battery supports that. That's a huge amount of current, especially if you're boosting it. I think in the boost, like I said, it's 2.5 amp. That's still a lot. You know, that could be second four amps out of your battery. So obviously if you're using, you use this for RC circuitry, but you know, a small battery won't be able to provide that. You need, you know, one of those like 18650 or something batteries. Okay. Next up, iSquad C is really simple. There's a couple of stats, you know, there's a device you can read and then there's a vout one and vout two register. I think these are all 16 bits wide. And so you can set the output. You're like, why are there two outputs? Because you actually will switch between them, which makes sense. Because usually you would set this up to have like 2.8 volts and 3.3 volts and then use a GPIL to like immediately switch between the two voltages. This means that when you want to go into a different mode, you don't have to send the iSquad C signal over and over again. You just switch back and forth. So when you're doing the radio or you're doing the motor, you can go up to 3.3 volts or you need or 3.5 or 4 volts. And then when you're not using this like high voltage, high power peripheral, you bring it back down. And then if you have a micro controller that has clock, you can PLL adjust the clock, combine that. You could have your micro controller running as at little as 2.5 or 2.3 volts. And at a lower frequency, you can save a ton of current while still keeping your micro controller running. So a lot of power savings can be squeezed out by using this chip. Here's the layout. One thing I like is it is a BGA, but at least you don't have to like get signal out from the middle. You can use this. I mean, they have a four-layer board here, but it's not a bonkers four-layer board. It's like you're not using any... Doesn't look like you need any bird vias for it. Well, of course you can. And then there's the valve board available. So ready to go. Input output and all the configurations on little test clip leads. So if you want to get started, all this stuff is in stock. A digickey. That's right. And for good price, it's like less than $1.50 in quantity. It's amazing for a buck boost converter, three amp outlet. Okay. And that is Ion of the Island. Okay. Now we're good to go to springy. Now we're set up for native restore and get all that free stuff too. Okay. Let's go over to... First up. First up, we have the Q-Bot Pro. So I think we have the original Q-Bot. So this one is kind of the same thing. You plug the micro bit in, you get motors and sensors, and there's a sonar for distance and two wheels. The big update with this one is you can now use an 18650 battery, which we do not stop, but you can get them on various online sellers or sometimes I think in some hobbyist chops. And you can then use it as a rechargeable battery pack so you don't need an external battery pack. So we're struggling for the people who are comfortable and okay with getting this other external battery and plugging it in. Keep in mind that we do not sell that battery ourselves. Next up, we have some ESD plastic tip tweezers. So these are plastic tip. So just be aware that they're not for hot air rework and don't get your soldering tip too close to them. But they're ESD safe and they have like these soft replaceable tips which some people might like. So good for picking up components. You can show them really fast on the overhead maybe. Oops, hold on. It's got weaked. This is my pair. It's got a little bit melted and damaged because I was experimenting like, what happens if you do heat it? Turns out you can't. But these are nice and delicate. So they're good for dealing with components where you don't want metal tips for some reasons and you don't want to the possibility of scraping or scratching them. Good. Next up, we have a new BFF for Shau and QDPI boards. This one features the BNO-055 nine-dough sensor plus the BMP-280. So it's a 2-4. It's like 10 or 11-dough, I guess. What's nice about the BNO-055, as you see here, it will just give you quaternion or oiler. This is oiler angles out. Immediately you do not have to do any fusion. You do not have to keep track of your error. You don't have to do your magnetometer calibration. It does it all for you, which makes it a little bit more expensive, but means you can use any processor. Which is great. People really like that for robotics and motion detection. The second thing is the BMP-280 on there is a barometric pressure sensor. And you're like, well, what does that have to do with the nine-dough? Well, you can use the barometric pressure sensor for altitude detection. So you can not only tell the X, Y, and Z coordination in space, but also how high up you are. If you pair this with a GPS, now you can pretty much identify anything perfectly within the confines of Earth's atmosphere, which would be kind of cool. And it's a little BFF board, so you can just plug it right into the back of your QDPI. Or you can solder it directly into the back, if you like. It's got little cast-related pads even. But we like to use little skinny stacking headers to make it a nice compact package. But a lot of people want to do motion or maybe you want to make it the tiniest little drone. This would be great for that. That's it. Okay. Next up, we have the TSSP77038, the 038 sensor, 38 kilohertz demodulator. Okay. So this is an interesting chip because a lot of people are like, oh, it's an IR remote receiver. Yeah, it is, but it actually does a little bit more than that and a little bit less than that. So we're going to show off our IR receiver in a bit. But what a demodulator does, it doesn't have any brains. Like IR receiver chips usually look for and try to understand whether it's an IR remote signal and they only pass valid IR signals from a remote control. This doesn't do that kind of filtering. It will pass, anytime it sees any 38 kilohertz infrared signal at like 940 nanometers, it passes the demodulated signal along. Why would you want to use this? Well, IR remotes, like I said, you can't send a continuous signal of IR remote on an IR remote. Like here you have to stop and you send it again and you see the little blips. If you want to use a break beam sensor that is modulated so it's not as affected by ambient light, if you want to do a proximity sensor that bounces modulated IR light, this is more for that kind of experimentation with modulated IR light. You could use this for the remote control. Honestly, I don't recommend it. I recommend getting an IR remote receiver instead because that'll actually do like the demodulation for you but and filtering for you. This is more for like science experimentation where you want to mess with IR light. Okay, and start the show tonight. So as you, lady, or our team, our customers, everybody who makes this video is... The IR receiver board. So that goes along with the IR demodulator. This board is specifically designed for people who want to do infrared remote projects. You can see like, you know, you press a button and it's like, I've received this code. So we sell in the store like little breadboard friendly infrared receivers. The problem is that you can't mount them easily and you have these like little thin legs that you then have to solder wires to. What's great about this is that you can plug in two millimeter JST connector and then you could plug into a board and you can see there's like the wiring is very simple. Another thing that's nice is there's a little red signal indicator LED to let you know that it's received signal and there's two receivers on there that you can select between depending on whether you want horizontal or vertical coverage. So if you go to the overhead, I can have a prototype here. It's green, but otherwise it's the same chip. So the first thing is... Oh, that's really bright. So let me put off that for a moment. Okay. First off, there's two receivers. There's a vertical and a horizontal and that's because maybe you want to have something that's like edge mounted and you want to have it pointing out or something flat against the wall and you want the signal to have as much coverage on the horizontal plane. So between these two, you obviously don't get coverage on the back. Although this one does have a little notch and like this is translucent. So you could... You probably could get some signal even if it was coming from the back. There's a switch to select which one you want to use. You can't connect them together because if they have different signals, they will fight each other. And so you have to select which one you prefer. But on the final version, oh, if you go to this photo... I mean, I apologize, I mean this one. On the back, you see this is IRH-IRV. If you want, you can get the individual signals from each one. If you have two infrared inputs on your microcontroller, as well as the signal, which is the selected output. And then... Okay, so can you go to the red again? I forgot, I had a prototype. And then another nice thing. Let's make this less bright. As you can see, when you send messages, the signal LED goes off, lets you know it was received. And then I just have a little example code here. What's the max distance for IR? I'd say up to 25 meters if you're lucky. It kind of actually depends on the transmitter, not the receiver, right? The receiver will, any signal you get, it'll work. And this will probably work about 10 meters away at the most. Maybe like, you know, it's best before 10 feet. It's meant to be like a room remote. But we have an IR transmitter dongle that we sell. And you know, it's very high power. And if you use it, yeah, you'll definitely get like 100 feet plus, no problem. Okay, so this one, as we press each code, each code is being decoded. And it's like telling you, you do have to, you know, the output is the demodulated signal. It has to go into my controller that has, that has an infrared receiver. So in this case, I'm using CircuitPython. Arduino also has IR receiving. Just make sure that you use the right pan and the right library. You have to decode it. Like this is in any C remote. So this board doesn't do any of that like, oh, I have decoded it. And to also tell you what the protocol is, it just sends the bit stream out. And then your microcontroller or microcomputer will have to actually convert that into which code and which button was pressed. All right. And that is new. All right. Don't forget you can get some of this stuff here. Springy's code. We're going to answer questions. I have some lined up, but first we're going to do some top secret. Okay. Oh, it's in the vault. Trim you on. Okay. So we got some more Trinkies being designed. So this was a request from Bill Binko at AT makers. So this is a TRS Trinkie. And the thing that he wanted was basically a USB adapter that would connect to a TRS 3.5 millimeter audio jack but did not have one pin connected to ground or power. It's like every pad on the audio connector was a GPI or analog input because this connector format is used for different accessibility tools and they have different pinouts. And so you want to be able to dynamically decide based on the code which is the input pin, which is the output pin, which one's grounded, which one's power. So I just, it's got a samd21 and a neopixel. And then every pin on that TRS plus the two switches again goes to different GPIO and then you can read them all. And then to make it mechanically stable, it's got a USB-A through-hole connector. And then we're looking at this like cool Windows 10 HID RGB LED array like protocol that they've come up with. And we're like, oh, that's basically like neopixels. So it'd be cool to have like a USB HID to neopixel converter. So it's a little pixel Trinkie that you could use also with Python or you could program in Arduino. It could be standalone running and it just gets five volts. There's a level shifter and it can control two strands of neopixels or one strand of dot stars because we use two pins. And the samd21, you think of it as a small chip, but it's got 32K of RAM in Arduino. You can drive like 10,000 LEDs if you wanted to. So maybe we'll make a little USB interface code so you can write pixel data from any application and we'll just like pipe it out very easily. And then finally, a lot of people are like, hey, can you make some of these Trinkies in USB-C? But I'd have to find a plug that's a USB-C plug and also mechanically stable like the USB-A plug. So I kind of made a breakout, hopefully this connector that we found on the Great Search last week. So watch that video. We'll work and it'll be mechanically stable and we'll use it to make some USB-C Trinkies. Best top secret. Yeah, it is. Okay, we're going to roll right into questions and then we are going to bounce to try to get out of here. Yeah, thanks everybody. Yeah, all right. So question Lady Aida. The first one is, you did the max distance for IR. Could you compare the floppy disk archiver and the emulator prototype with the release Adafruit floppy feather wing with 34-pin IDC connector? The floppy feather wing is kind of like a very simple board that's just, you know, you can run any code on it but it doesn't have buttons and a TFT. It doesn't have like, it doesn't have a level shifter. It can't emulate because it's set up for only writing to disk drive but it's basically for like floppy experimentation whereas the floppy board is kind of an all-in-one. You can do anything with it. It's like a multi-tool for floppy. Okay, next. Is it possible to keep the lithium ion batteries at the same time to make the milliamp hours bigger or larger? You can by the clever use of chemistry. One thing you can do is depending on the anode chemistry you can have it be a 4.3 volt. Or 4.4 volt battery I think they get up to depending on the chemistry used and that will just give you more voltage. So then when you buck it down using the RT6160A you'll get a little bit more capability. In general, it depends on the quality of the battery. You know, some batteries are high density. Tends to be the 18650 size because that's kind of where like a lot of the technologies is happening because they're used for making battery packs for like scooters and cars and you know every other kind of electric bicycles and all that good stuff. So there is sometimes variation based on the size but not from live polys as much. Those are kind of like the sizes very much related to the capacity. Okay, and let me see if there's any more because we had them lined up but I think that might be it. Thanks for helping us get out of here late tonight. Thanks everybody. Yeah, I think that is it. We still got a lot done. Yeah, we did. There is. That's how we're getting stuff done. We're cloning ourselves. So we'll see everybody next week. Thanks so much. Don't forget the code is springy. Okay. This has been an Adafruit production. It is your moment of zener. Bye everybody.
