 We're getting stuff back in stock because one of the things we'll be able to talk about later, it's Ask Engineer, me, Lady Aida, the engineer and with me, Mr. Lady Aida on Camera Control. We had a fun filled, informative one hour show for you. We'll be here til 9 o'clock talking about making, hacking, coding, soldering, 3D printing and more broadcasting live from downtown Manhattan where we do all that stuff you just saw. That was shot here in New York, making stuff, making stuff almost 24-7. But now we have a show, and we're going to tell you all about it. So Mr. Lady Aida, why don't you tell them what's on tonight's show? On tonight's show, the code is GloVlo because things glow.

Wait, is it shipping? It is. We're about... The person who's always like... We're going to get inbox shipping. Where are you? They're busy. They're opening up. So we're about halfway through the Adabox shipments. You can check out... Let me go to... Let's see if I got... Do you want to have the report up? Well, no. I'm not going to do the reporting because that's like internal stuff. But you could go to adabox.com and you can see that we have updates and we also have the unboxing video. When is the unboxing? It's going to be live in 27 days. March 20th at 8 p.m. We have a little YouTube link there. We'll be doing it live across all the channels. So Gary Adabox is ready and more, please keep it a secret to the young folks. We'll get through all of them and then we're going to make sure anyone who just signed up can catch up. We also understand some people... Good move. Lots change in the years. So thanks for your patience and hanging in there, everybody. But it is happening. If you haven't already, if you are a subscriber, just make sure you log into your account. Your payment and address. We do have a couple slots too. We do. We do. So if you want to... We haven't notified all the people who signed up to be notified when their subscription's available. Yeah. But you, the viewer watching right now, get the download sneak peek. There are a couple spots available you can sign up right now and you will get this box. Yeah. And then we should be on track to do the next one, the next one, the next one. And we had some choices of what we could do and we basically said, well, let's keep doing it. And thanks for your patience, everybody. It was a... I'm glad we do a weekly show because we're able to get the word out and talk about subscriptions, how they work, and then also the chip shortage. We did a segment around it. And if you look at the data boxes that we're coming out with, you'll be able to look back at the park shortage and be like, oh, yeah. Oh, yeah. Oh, yeah. That was gone for a year. Now they were able to get it. Now they can do, you know, thousands and thousands of data boxes. Yeah. Okay. We do a bunch of live shows, special thanks to Melissa who just did a show and tell. We were getting our show ready. So we'll be watching that. But don't forget every Wednesday, 7.30 p.m. is show and tell Eastern Time. We drop the StreamYard link and Discord. You can show maker spaces, actor spaces, retro stuff, books, projects you've worked on just about anything. All are welcome. On Sundays, we do from the Desk of Lady, that's in two parts. Lady, what did you show off this week? Okay. This week, oh, I showed off my high voltage UPDI program. So a couple of weeks ago, we did the standard UPDI program or low voltage. And we put that in the shop because that was an easy one. And then the high voltage one is the one that gives you a 12-volt pulse, which means that you can use the UPDI pin as a reset button, which is like for people who use AT tiny, it's like a kind of a funky weird pin. And you can use fuses to configure it, but then you have to use a high voltage pulse. So I talked about that. And I also talked about a revision I did to the S35710 low power timer chip. I was hoping you could do like deep sleep, like timer capability, but like it turns out I can't. But he's watched I can't keep ability. So I just talked about the differences between the two things. And then I think I talked about a different micro power timer I found. So yeah, just a couple of chips and just showing some revision. So and then the DS40420, I revised it to have a little boost converter because it turns out it's a five-volt chip, not three-volt chip. So a lot of little revisions got worked on this week. Okay. Then we do the great search. That's when Lady80 is repatriate of engineering to find things on digikey.com. What did you look for this week? Okay. This week, somebody on social media was looking for a 7805 to replace their SEGA master system. Or maybe it was a Genesis. I don't remember which one. That's cool. They're SEGA and so they needed a classic T0220705 and I'm like, it's such a classic part. We got to cover this. So we found one or one and a half amp, 7805, there's a two amp version, although you'll need to heat some of the heck out of it. And then we found a couple other options that are two amps that are not discontinued, although they're a little bit more expensive. Okay. We do that every Sunday. Usually around 7 a.m. to 5 a.m. or a clock. On Tuesdays we do JP's product pick of the week and here it is this week's highlight. It's my product pick of the week. This week it is the NeoPixel feather wing. This is a feather wing with 32 RGB NeoPixels on it. It plugs right into your feather or doubler tripler quadrupler and you can control it over pin six by default or cut that jumper and solder up any of the other GPIO pins, which means you can use it on pretty much any feather. You can see what's this one doing. Okay. This is based on some cool code that Liz wrote, which takes in the PDM microphone. I have a little PDM microphone soldered there to the doubler, brings in sound, converts it to light. So this is a sort of a meter. I have it just running up from zero to 32 on the NeoPixels there. You can probably see those colors a little better there with some diffusion there, some diffusion acrylic. Wow. Wow. Wow. There you go. Pretty cool. And there is my product pick of the week this week. It is the NeoPixel feather wing. GQ's workshop is on Thursday. That is tomorrow. Oh, no, no, I think this Thursday is not. And it's not happening this Thursday, usually Thursdays. And then Friday, deep dive, it's either with Scott or a Temp Femiguy and you can check that out at 2 p.m. Pacific, 5 p.m. Eastern every Friday. Let's do some Python on hardware. We've got some news and reviews and more from the newsletter. Some good projects in the newsletter this week. So this week, we cover a lot. So in addition to CircuitPython A210, release news, you can check out the notes, news in the industry for those who design Python on hardware, renaissance bot Altium for $5.9 billion, more consolidation in the industry. So Autodesk has Eagle CAD and renaissance has Altium. And Kikad or Kikad, depending on how you pronounce it, is free and open source. Some of our folks at Adafruit use Kikad. We're moving towards it. We have a lot of stuff. Yeah. Eagle, obviously, we'll see what happens in the industry. And what folks use. So is there any other ones that people use that are going to get gobbled up already? But I think that isn't owned by anybody. It's another popular one. Altium is very popular. A lot of people use Kikad. Yeah. That's kind of the one. All right. It's like the number one most pirated. And then, yeah, our CAD is used by some people as well. Yeah. But I use Eagle CAD. And then Eagle CAD is kind of going away. It is. 2026 is the end date. And I'm slowly, slowly, you know, I just wanted to get all the revisions done and I didn't want to take two things. So I wanted to do the revisions. Now that the revisions are done, I'm kind of looking again at Kikad. Yep. Telegraph interviews have been about the upcoming stock IPO that is Raspberry Pi going public. Hands-on with the Best Pirate, some Python packaging and Rust, you have another Raspberry Pi 5 review. Helen is interviewed by the Embedded FM podcast, really good podcast. Check that out. And then all the projects. This was a neat one. This was that Radio Shack, you know, 101 and how we added the Pico. Our popular post of the week last week was the Raspberry Pi alternatives. We also talked about Blinka on the show last week. And more. And then we have some custom firmware. We've got some work today, by the way. Hot news, by the way. If you're like, I want to use it for a second. But let's talk about, you wanted to talk about there was an update for Memento. Yep. So Memento, specifically this board, had a little bit of a bug in CircuitPython 9, made a one and earlier that made it so that if you were using the internal file system, the CircuitPy drive, and you dragged really big files, you could accidentally crash the board because it thought that it had a three megabyte drive, but it actually doesn't. It has a one megabyte drive. And so it gets very confused. Good news, it's not going to damage your hardware. But what you should do is if you have a Memento and you are running, if you've installed something before CircuitPython 9, beta 2, you'll have to erase the file system to kind of reset the board. Or you can install the factory firmware reset over again. If you've never installed CircuitPython before, as long as you install beta 2 or above, you won't get that bug where it accidentally thinks that it's three megabytes. But it's not. Again, it doesn't damage your hardware, but we want to make sure you don't crash your board because that's sad, you don't crash your board. So thanks, Jeb Blur and Dan Scott, who fixed this super fast. Okay, great. It's all part of our newsletter, you can go to AdafruitDaily.com, sign up for the Icon on Hardware newsletter, or you can read it online, you can read on GitHub, you can do an RSS feed. It's all part of AdafruitDaily, a completely separate site, so you don't have to worry about getting spammed. We promise. But what are promises anymore? You have to prove it. You have to prove it. Yeah. So that's all for us, hardware news and more first up, let me go over to the Open Hardware Summit. So ashwa.org, you can check out the summit. They announced the speakers and more. It's May 3rd and 4th. It's at Cordia University and the less make the less piece maker, less space maker, less space maker. Not only can you get the tickets, you can see the schedule, but we're community sponsored. So some of the folks that we know are going to be there, check it out. You can also see some of the presenters you want to go to the presenters and this is cool. Yeah, companion robots, people with green hair. So check it all out and guy and then there's a team and there's a cat and a cool hat and then somebody with a neat filter on their image. All right, I can't wait to read this. I'm Becky. We know Becky. That's right. We also know Lee Weekly. Great. So check it out. This is like the old all star team. Yes. And one of the cool things is there's a lot of new folks. There's a lot of people. There's a lot of new folks that Open Hardware Summon is a place where you see a really interesting, complete, diverse cast of folks that are doing something in the world of open source and specifically open source hardware. There's not really a conference like it, so do check it out. It's cool. It's edgy and it's all open. Yeah. All right, let's go to speaking of open source hardware. What guides do you want to talk about this week over on Playgrounds? Well, we have some features. I think we... Yeah, I think we had a couple of projects in Playground, but with the learning system, we only had one guide this week. Last week was like a bumper crop. Sometimes it comes in waves. Now we got the guide for the Neo RGB Stama and Newboard that we released a week ago that you turn any analog RGB LED strip into a gigantic Neo pixel. So check out that guide. We also made some updates to the Adabox 21 guide, but it's a secret, so don't open that unless you already got your Adabox. That's it for guides. And then Playground... I don't know. We want to look at the Playgrounding. Yeah. Have you looked at Playgrounds this week? I did not look at it. So you're rehearsing cool stuff. And then we also added the little badges loved by everyone. We added the badges. Yes. Oh, like tied to our guide. And then that was from last week. So not as many this week, but I like the wave viz. And I think SeaGrowers did a lot with the SynthIO, so it's like you're a SynthIO fan. We should eventually make a week and subscribe to some authors because that'd be cool too. Yep. We're at more creatures all the time. Yeah. All right. Let's do some factory footage. And that's what we're making here in New York City, 3D printing. This week we have speed up. We're going to go speed up right to INMPI, and we have a lot of top secret this week. And we want to try to get on here on the dots where we're going to keep moving. Here is this week's speed up for no painter. Let's do some INMPI. INMPI I've brought to you by Digikey. This week it is ST Lady Aida. What is INMPI of the week this week? Okay. This week it is the T. Oh, you'll have to click on the link, isn't it? Yeah, I gotta go. Yeah. Can you click on them? Yeah. Okay. The TSC 1641. I'm going to make sure I get the part number correctly. This is from ST. You can even see the ST logo on the chip. I think this is their first digital power monitoring chip. So they're kind of getting into this new industry. ST has done a lot of sensors and of course, microcontrollers, but I think this is their first power modern and definitely the first like Mipi I3C one, I think, which I thought was kind of interesting. So this is a power monitor for up to 60 volts, 16-bit ADC built in for monitoring voltage, power, and current. Very, very small, 3x3mm DFN10 and it has both I2C and I3C interfaces, which is kind of neat. So starting to see I3C make it into some chips. So the traditional way of, if you want to measure the current going through a device is in the olden days, you would use an analog system like this where kind of in the middle, you see there's a 0.1 ohm resistor and you use a precision op-amp that can go as, you know, load of the rail to rail to the ground rail and you can add some gain, looks like a 47 time gain on the voltage across that resistor and then you can calculate the ampere is going through your load and then you can take the voltage and use a resistor provider on the top to get the voltage from a high voltage down to your analog input and then you can read it with a microcontroller. Now you've got low side monitoring and voltage monitoring and then you can calculate the power, which is super great and everything except for two things. One, a lot of components and you can only do low side easily. It's hard to do high side. You can kind of do it, but you need an op-amp that can be that high. Otherwise, it gets like very complicated with the common voltage. And second, you need two analog inputs. Maybe you don't want that. And third, you know, it's not as easy to set up interrupts or have low power because you have to have the op-amp and those just provider constantly on, which is why this is a cool chip. So this chip has a differential input that is safe up to 60 volt common mode. So you can do either high side or low side measurements. It'll measure both the load and the the voltage across a very small resistor that's either placed again at the top or at the bottom of the the power rail. And then you can read it 16 bit ADC, you know, it's two of them, one for voltage, one for current. You can read that, do power calculations, set alerts, read the temperature, all sorts of stuff. And it all comes through I squared C or I3C with an optional alert pin for easy use. And then there's two address pins. So of course, you can have up to four of these on one I squared C bus or like, I think an infinite number in I3C, it's kind of cool. So the high side is what is, you know, preferable. Like I'll say whatever I do projects like this next one up here. You know, this is an earlier design from a couple of years ago. High side is better because you don't have a floating ground, which is one of the issues. If you do low side, then the ground of whatever you're measuring the load of is going to be a little bit higher than your earth ground, which like might be okay, but sometimes can make your circuitry a lot more complicated. Also, you run the risk of accidentally shorting the ground, the floating ground to the earth ground. And then like it says, that there's no current going through it and your calculations are all wrong. So high side is the way to go. And it's going to do up to 60 volts, which is nice because, you know, you can handle basically very large battery packs, solar panels, electric vehicles, you know, etc. The current is dependent on the resistor value. I'll show you a little bit how to calculate that. But basically, you know, easily can do 10 amps. OK, so let's skip ahead. OK, so this is the specifications. The chip itself is powered from about 3.3 volts. But like I said, you can measure up to 60 volts. The total conversion time, you know, can also do averaging and filtering over it. So, you know, you don't want to just measure necessarily like at a point in time, you want to say like over, you know, 10 milliseconds, give me the average current and the average voltage, because if you have a very spiky signal, you don't want to like think that the high point or the low point is representative. So what's really neat is this chip has built in filtering. You can configure. And then the really neat thing about it, you know, compared to other power chips is that it has I3C support. So what is I3C? It's it's it's like I3C is like improved I2C. So like inter chip communication or whatever. This is improved version. So I3C kind of takes the best of I squared C and SPI and combines them. So, you know, with I squared C, which is in the middle there, you can have multiple sensors all connected to an I squared C bus. But then they all have IRQ pins that are separate. Also, all the peripherals have to have separate addresses. You can't have address collisions and they're limited. You can't really go above like one megahertz. It's rare to see chips that go above one megahertz because they have this pull up system that slows down the communication. When SPI, on the very right, uses many more pins and you need a chip select for each one. So you still have like extra pins and you need extra interrupt pin for each one, but it's much, much higher speed because it doesn't use a pull up system. It uses a push ball system so you can easily get 10 megahertz. Like no problem, 20 megahertz, 24 megahertz is very common. So either way, it kind of combines the both. You can go from pull up to push pull modes. You can go up to 12 megahertz. Plus, there's no separate IRQ lines required. The IRQs are actually handled by the SDA and SCL pins using what's called like interband signaling, which is kind of handled for you transparently. And also there's dynamic addressing. So you don't have to worry about address collisions because on boot, the I3C controller can tell each device, hey, generate yourself a dynamic address that doesn't collide with anybody else's. Just quite nice. If you have one of multiple chips with the same address, that is an issue. I will say not every chip supports I3C. It's pretty new. We talked about it like on an INPI like about a year ago. We're starting to see it more often, but it's still kind of new. That said, it is the future. We're going to see more and more devices and chips support I3C. So you can use this as I squared C, but if you have an I3C capable chip or microcontroller or microprocessor, you can enter I3C mode by doing this dynamic address assignment. So it's backwards compatible, but for future use, you know that you have an upgrade path to a faster processor. And this is nice because it's a nice upgrade over the INA series. So like, you know, the INA, I think the 227 is kind of the closest in voltage and precision to the TSC 1641, but the TSC 1641 is less expensive. Competition is great. Thank you ST for making better chips that are cheaper. So we'll make everybody work a little bit harder. And of course, as customers, we benefit. So as I mentioned, you have to calculate and include the shunt resistor. That's the resistor that the current goes through. And there's two things you want to balance. If you have too big of a shunt resistor, you lose precision. But if you have too small of a shunt resistor, you max out how much current you can measure. So you wanna get that, because the maximum shunt voltage you can measure is like eight millivolts, I think. So you want to, maybe it's three or two millivolts. Maybe it's plus or minus eight. Yeah, it's plus or minus eight. So you want to balance between being able to measure the highest amount of current that you're likely to need to measure without maxing out, topping out the internal ADC's range versus you want to have precision at the lower current. So if you get below a couple of milliamps, you still want to have a couple bits of precision so you can tell the difference between one or five milliamps. So you choose it as an engineer. They give you the calculation for guidance, but basically a power shunt resistor about 0.10 is probably a good start. There is also an eval board that looks like it's Arduino shield compatible. Also for their Nucleo board, so easy to get started. It's I squared C, so pretty much every microcontroller board can talk to this chip and it's in stock. In stock. Right now. Yes, the chip shortage is over. Yeah, and we have a video, we're gonna play that and then we're gonna get right into new products. Does your power supply unit need to be precisely monitored? Do you wish to raise alerts if your battery packs go over or under current, voltage, power and temperature? The TSC 1641 is our new generation of digital power monitors. It enables safe monitoring thanks to its accurate integrated ADC, its extended voltage range and its flexible bus interface, the new MIPI 3C bus. Let's jump to our demo of an electrical skateboard. Here we monitor the battery voltage and current under different speeds. We can see the alert when the current goes higher than the limit we have established. So how does it work? The TSC 1641 integrates two 16 bit channels. One is for the current measurements of a shunt resistor with a common mode voltage up to 60 volts and the other one is for the load measurement up to 60 volts. The power is computed precisely thanks to the fact that they are perfectly synchronized. And die temperature can be measured too. The TSC 1641 uses the new MIPI 3C interface to communicate with the microcontroller and set up the internal registers for configuration, speeds, threshold or the currents, for example. For this demo, we communicate with the new STM32 H5. The MIPI 3C interface has a huge advantage in that it can be configured using only two pins, clock and data, communicates at 12.5 megahertz and implements upper layer commands known as the common command codes. Concerning your industrial application where you need to monitor the current voltage and power to control the power budget of the entire system. In fact, the TSC 1641 is meant to do that in a precise and secure way. For more information, please visit our website st.com and read our data brief of the TSC 1641. Thank you. Happy hour. Okey-dokey, don't forget. Blah-blah, that's the code. Let's kick it off with the numbers. New, new, new, new, new, new, new, new, new, new, new. Revision. Revision. Okay, so this is back in stock. Finally, it's our dual eyes TFT bonnet, which makes it really easy to add two OLEDs or two TFTs and one some eyeball code on a Raspberry Pi. We are upgrading this code to run on a bookworm, but for now, I think you still have to use a older, if you can use Raspberry Pi Buster, I don't remember the one before bookworm, but we are working on it. Probably by the time you watch this video, I'll be updated. The revision for this board is it now comes with the two by 20 header on the bottom pre-soldered. You still want to solder on the connectors for the TFT or OLED, because depending on which one you are gonna use, but just a little revision and get it back in stock. Very exciting. Next up. Next up, we also have a revision to our 1.5 inch tri-color e-ink display. So if you want a little square e-ink with the SSD 1681 driver, you can get red and black on a white background. This has been updated to now have an i-spy connector. So wiring is a lot easier because you can just use an FPC cable to connect it up to like our QT Pi or to a breakout board. You can also wire it on a breadboard if you like, but if you want to mount it elsewhere, the i-spy connector makes it easy. Next up. Next up, we have this kind of a coming soon and we'll get a demo and a video for you. This is a 144 LED Neopixel strip with a nice neon LED covering. So you might have seen like LED neon. We see it usually in a single color. This is full Neopixel. So you can not only change the color of the neon strip, but you can also change the color of each individual pixel, just like an LED strip. And it's got two connectors on each end so you can extend them. Otherwise it's like pretty ruggedized. I don't know if it's, I wouldn't dunk it under water, but definitely if you're doing like outdoor projects that you want to be able to take outdoors and then maybe not leave outdoors, but for events or to attach to your bicycle or whatever, this Neopixel neon strip will do nicely. Okay. And these are kind of stars of the show because of glow glow. So what is this? More glow. We have, this is the neutral white version of the double-sided LED strip. So this is a 12-volt, single-color LED strip, but what's nice is that it has LEDs on both sides. You see like as this spirals around, there's like LEDs no matter which way you look. So it's great for like a nearly 360-degree glow. Good for illuminating stuff. We have cool white and warm white, this natural white kind of gives like, it's not hot, not cool, not red, not blue, try in the middle, just right. It's like Goldilocks in the three LED strips. Now you just give it nine to 12-volt power. You can also PWM it with a transistor to get a nice, beautiful illumination. It's new this week. No, no, no, no, no, no, no. Okay, like I said, we're gonna wrap up early tonight. We hope we got some stuff to do after the show, but that doesn't mean we're not gonna do a gigantic top-secret section. So you can post some of your questions in Discord if you want, we have a couple of startup, but we're going to start off with top-secret first, as usual. Okay, the first part of top-secret is gonna be a video, and then we're gonna go through a bunch of boards. One, two, three, four, five, six, seven new boards. Seven new signs. I really do, what's this? This is an AT Tiny 816 board that's programmed over UPDI. It's interesting here is I've got a button and when I press the button almost the LED stops blinking because I have the UPDI button set as a reset button, which is kind of nice. You can program or reset the circuit. Normally, the reset doesn't work. What you have to do is actually enable the ability. Hold on, let me find it. UPDI, there you go. Danger, bricks chip to that high-voltage UPDI programmer. So when you set it to be a reset, you can't just send the UPDI signal normally because that could be confused with the reset signal. You have to send it at 12-volt pulse. And so I have a version of my UPDI friend here, which is in the shop. This version has a 12-volt high-voltage pulse. So there's a little boost converter and analog switch. When the RTS pin toggles, it sends a 12-volt pulse to tell the chip, hey, I wanna put you in programming mode so that when you can program it or use it as a reset input, kinda handy. So now that I know this works, we're gonna get this finished up, fix this little blue wire hack, and get it into the shop. All right, what's this? Okay, this is the back of, oh, can you maybe click on that first? This one? Yeah, that's the front. Yeah. Oh, I see. Okay, yeah. So this is, yeah, so there's two, usually there's only one image, but there's two. This is like an evolved prototyping pie cowbell. So I wanna get back to doing some cowbells. We were doing them in like 2022-ish and then kind of like took a break. Again, back to it. So this is the prototype one, but if you look, there's terminal blocks on each end. And so what this means is that you can put like stacking counters on this and you can plug it into a Raspberry Pi Pico, put the Pico on top and plug into something else. And then you have terminal blocks so you can easily wire up sensors or other devices without soldering. So it's like meant for making prototyping a lot easier and then also getting access to pins, even if you have stuff plugged into the Pico W or Pico. Okay, that's awesome. This is my revision for the S35710 timer. Again, I thought it was a low power timer, but it's actually a watchdog timer, which is a different thing, but still kind of useful. So I updated this to add a, first of all, I changed it the inverter to be an end channel. I also added a little slide switch so you can determine whether you want to have the output inverted or not. Okay. Also getting back to some trinkets. The opposite of a chip shortage is a chip surplus. And I actually have a little bit of a surplus of the CMD21E18s. I had like none for like two years. One of the things that was a little annoying about the part shortages, we were kind of told, you have to order two years worth of inventory or a year's worth of inventory. And we're like, okay. And then they shipped all year or two years worth of inventory at once. So it kind of got like two years worth of new chips, which means I want to design a whole bunch of trinkets. So I thought this would be a fun, easy once. The SHT45 is a nice precision temperature and humidity sensor. This means this little board, you can plug it into your USB port on your computer or your laptop. And boom, you now have an instant precision temperature humidity sensor. It's going to pipe the data out over the USB serial port in like CSV format. And you can take that data, you can plot it, you can manipulate it with some other program like Python or VS code or Visual Basic or whatever. So it's got a little NeoPixel and a reset button. So you'll see, and there's a capacitor sensor on the end. This is, okay. So I was working on the DS4420, which is a monophonic audio volume, like slash gain chip. And then I, so I was like, oh, when was I working on it? And then I realized we did an INFPI on the stereo where I don't like found the same chip. So the TPA6130 is a stereo headphone amplifier that can drive 16 ohm loads, which is kind of nice directly. And you can adjust the gain for two differential signals at stereo input over I squared C. And I was like, oh, it's going to be kind of useful. You have audio output, you want to adjust the gain and you want a headphone amp, you know, bonus. Hopefully it turns on, you know, like when you plug it in, like you don't need to change the gain. It just acts as a headphone amp to start, but we'll find out. It's a little semi-QT board to do that. I also have a bunch of extra BNO055s and BMP280s. And I thought this would be a good little sensor BFF to go onto a QT PI or shall board, basically gives you 11 DOF. So you get three DOF of accelerometer, gyro-magnetometer, and the BNO055 does the fusion for you, which is kind of nice. So even if you have like a very slow chip or using MicroPython, you'll get quaternion data out. And then the BMP280 will give you barometric pressure and temperature so you can do altitude detection. So it's gonna be good for like little drones or robots or like, you know, motion detection. And then this is that revision of the DS4420, the mono-phonic audio amplifier or audio gain adjuster. Just needed like a new power supply. That's a whole bunch of new hardware coming. More too, I've been almost done with this camera, camera bell. Okay, well, for new products, GloGlo is the code. We're gonna go over to Discord. We have some questions lined up. Let's answer them and then we're gonna get out of here a little bit later. Yeah, okay. Bo used to go over. So it's like, it's in the bank. You know, with the draw. So you talked about what is I3C during INMPI, but do you wanna have a little brief overview in the question cycle? Yeah, so I3C is kind of the, you know, backward compatible upgrade to I2C where you don't have address collisions anymore because addresses are dynamically generated. You can go much faster, 12 megahertz instead of like 400 or maybe one megahertz. Probably can also go longer distances because you don't have the pull-up resistors causing, you know, big delays on long wires. And interrupts are handled interband. So there's no need for a separate interrupt pin. This is a, maybe long overdue. It is long overdue. I think it's very popular. It seems like we should have. And they got rid of clock stretching because they were just like, we're not doing it. But you have interband signaling, so you use that instead. But that was very smart, they got rid of it. Anyone know where I can get some help designing a set of LED poise? We have a guide on LED poise that we've done. It's a little bit older, but you can. I don't know if that's what I'm trying to say, maybe. Checking the learn guide, we search for LED point. Oh, I, mm-hmm. Okay. Question related to IMPI. Could you include an accurate enough I2C, I3C digitally controlled potentiometer as a short resistor and a breakout? For the new SEM, load monitoring chip or is that particularly expensive? And would it make more sense at that point to try to use an AT tiny or something as a I3C, I2C, overloaded, CSAW, and some cheaper nod? I squared C digital potentiometer. There's no digital potentiometer that goes under one ohm. They always have like two or three ohms. So you're not gonna be able to use a digital potentiometer even if you wanted to. Okay. Next up, any good resources on learning about receiving, processing radio signals, thinking about potentially for digital signals beyond using an SDR with Raspberry Pi? It's tough to be getting one of those USB SDRs and just like messing around with some of the code available. I think that's kind of like, that's the easiest way to get started, especially with receiving, you don't need a license. But of course, if you get a license, yeah, then you can do transmission as well. Okay. How will I3C work with multiplexers? It seems like they might not even be needed anymore. There, I think we covered an I3C switch, but no, you would not need a multiplexer because addresses are dynamically generated. So you could have multiple chips of the same, like family address and they would get unique IDs. I don't know how you'd tell them apart. Maybe they have a serial number or something. That's a requirement. Okay. And what's the code? It's easy. Glow Glow. Glow Glow is a code. Yeah. And it is active until 11.59 PM tonight. We see if there's anything else. I think we have gone through all. Okay. Questions? Like I said, we usually go over. Yeah, we wanted to get out here 15 minutes early this week because we usually go a little bit over, but we have stuff to do. We're going to have some more stuff next week. This week was a little bit of a short, first off, it was a short week because we had President's Day and second, only known to your, kind of delayed a couple of stuff, but you're going to see all those, it's not out yet, don't ask. Come into the shop real soon. You're going to see a code to Glow Glow. Glow Glow. And don't forget, there's all the free stuff as you go and check out. Eight of Box is shipping. Yay. Check out Eight of Box.com. This will sign up if you want to get it before. You can sign up and don't forget to update your address. This has been an Eight of Box production. Here's your moment of Xenar. Thanks everybody. Have a great night.
