 It's a two sick engineers with a little bit of the weather, so we're gonna try to do this show. We're gonna just, you know, heads up, we were gonna cancel the show but we're like, let's just do the best we can, let's do what we can. So we're just gonna be, we're gonna be moving slow, slow but we're gonna do it. And we're gonna just try to hang in there because y'all are important to us, we want to get some new products out, we want to show some cool stuff, we got some videos, we got a lot of things, so we're just gonna, we're just gonna do it. Alright, well we're still broadcasting live and sniffly from downtown Manhattan, that's where we do all of our testing and coding and shipping and soldering, we've got a full show for you tonight, hopefully we'll make it a full hour, at least very close to one hour with lots of new products and videos, tutorials, island piano and more, including a discount code, 10% off, what's the code and what's on tonight's show? The code is analog matrix, 10% off, native restart all the way up to 1159, PM tonight or when I remember to turn it off. We'll be talking about, you know, some of the live shows we do, including show and tell, I'm just going to leave you Ada, great search, but we're gonna do a recap video of JP's product pick of the week, we got some made New York City factory footage, we have some 3D printing videos, we got IonMPI, brought to you by DigiKey, this week it's expressive, we got some top secret, we got some new products. To answer your questions, we do that on discordadafruit.it slash discord join all 39,000 of us, all that and more on, you guessed it, I'm asking that in here. Yeah. Okay, so freebies, if you put stuff in your card and you're using the discount code, you also notice you might get some free stuff. That's right, at the Adafruit shop, when you buy from us, not only do you get 10% off, but you get freebie goodies, so $99 or more will give you a free PCB coaster with this beautiful gold Adafruit design on it. $149 or more, we still have some KB2040s available with the RP2040 chip, four megabytes of flash memory, cast-layed pads, USB-C, Neopixel and some buttons and QT port. It's a Pro Micro compatible, so great way to upgrade your old Pro Micro projects. $199 or more in the Continental US, you get free UPS ground shipping and we still have Circuit Playground Express' $299 orders or more. We'll toss in our favorite mic control board that's round with cast-layed, with alligator clip pads, 10 Neopixels, SAMD21 chip and buttons and sensors and all those good things. It's a great way to get started with learning electronics and programming because you can code it in Arduino or code.org CS Discoveries or MakeCode or Circuit Python or even MicroPython these days. Yeah. Those are the freebies. Okay, we do live shows. Just a reminder and a special thanks. Well, so who did the show and tell? Thank you. It was just on Watch the Highlights and more on Sundays. We do desk-of-lay data, including the great search. And then on Tuesdays, we do GP's product pick of the week. GP, take it away. It is the Itsy-Bitsy ESP32. This is the version with the onboard PCB antenna. It has eight megabytes of flash, two megabytes of PS RAM. There is no USB cable plugged into it. And yet I'm able to code it right from a web browser. I'm running Circuit Python code here. You can see I've brought in time, board Neopixel, and then rainbow IO and a color wheel. I'm setting up the onboard Neopixel. I've set some little variables for some colors there. If I go and just change one of these, let's just change that to red, hit save. Again, notice no wires, right? And yet I've just changed that. I've just re-saved the code.py file. We can change that again here. Let's go to blue, hit save. And the Itsy-Bitsy ESP32 with the eight megabytes of flash, two megabytes of PS RAM, and the built-in PCB antenna. Okay, and don't forget GP's workshops tomorrow. And then Friday, deep dive with Scott, unless it's Tim, one or the two will be this Friday. All right, we're just gonna move right along to Python on hardware. Yes. So the newsletter. Okay, there's actually two things. I lied, I said I don't want to talk about one thing, but they... Yeah, you had a couple of things that we were gonna talk about. Okay. So if it is out, do check it out. If you're daily, subscribe. You know, new hardware. More circuit-proud boxes. For sure. Oh, all right. We released that put, oh, like last week, but you know, immediately people start using it. We have bug fixes and stuff. So we're up to 902 and working on 911 beta, which has even more bug fixes and some cool stuff, like I2S now used to be in our RP2040, you had to pick which pins in certain order, but that can be like almost any pin combo. It's kind of nice. The other thing that I thought would be cool to show. We'll talk about the Pimeroni stuff. Yeah. Well, first off, PyCascades, which is like this weekend. Okay. Yeah, Scott will be there. Scott's gonna talk. And he's going to post slides. I think the video is gonna be live too. As you can talk about Wi-Fi and BLE workflow for CircuitPython, which is a really nice way of working on a project. A lot of boards that support CircuitPython also have Wi-Fi or BLE support, like the Clue NR52840 ESP32 series chips. And the web workflow is actually very powerful and very fast. And you can like transfer files and you can use the REPL and you can save and restart your code. So it's kind of like over the air programming, but without all of the like really complexity parts of over the air, you get to like dynamically change your code. So check it out if you're in Seattle, but also it'll be online. So you don't have to go to Seattle if you're not in Seattle. Okay. And then, you know, we cover all sorts of hardware from our partners, from our friends, from folks that we just like, hey, here's something cool that you might want to check out. So this week you wanted to talk about the... I thought this was kind of neat. So this, yeah, so I'm fine. So I'm seeing where people do projects with like Laura as like a backend wireless communication protocol. So this is a board with like a 2.8 or 3.5 inch color TFT battery, you can click on this. It has an ESP32, I think S3 in it. And it was designed by primarily but for a university and is used as like a, the University of Sheffield, which is where Pyronys is in Sheffield. So I thought that was kind of cool. You know, a lot of these familiar components. I think this is kind of an all-in-one design. And what's neat is that it runs Circuit Python and we have support for the ESP32 S3. We have support for the battery monitor, the TFT display and the Laura module. So it's like getting it working in Circuit Python was really easy, I bet. Also it's like a feather adapter. I don't know, this sounds cool. I always like it when other people do hardware that is Circuit Python compatible and I'm sure it works really well. Cause it's, you know, yeah, as you can see. Plus, plus we're Circuit Python. We're Circuit Python. Some things are not in that list. They're not going to see what they are, but I'm just saying Circuit Python's supported. So check it out. And yeah, the S3 is with Circuit Python is great, especially with the extra PSRAM. So a lot of people were asking me like, oh, are you going to make an S3 Laura board? And I'm like, this probably just stock this. It's kind of does everything you want. All right, well then this is our hardware pick of the week for Python on hardware. Yeah. Okay. So that's our highlight for the week. Get that delivered to your inbox every single week. Don't miss it. Eight over daily. Okay, let's see some open source hardware news. Remember last week, we had 2,999 guides. 3,000 guides on Learn. Now we're up to 3,000, like two, well on our way. That's right. 4,000. We're up to 3,000 for helping make this the best, most used resource online for electronic projects. And here's the cool thing. So first off, every Adafruit product has a guide pretty much, which is great. And we also have lots of project guides. Some things don't even use Adafruit hardware. We have like wearable projects and sewing and documentation and photography. And we have, remember we had that guide series on how to run a hackerspace. A lot of it is about make our businesses. Make our businesses. Move it to everything. A little bit of everything. And what I really like is these 3,000 guides are like real guides. Like they're not, you know, like when I was younger, like I had a little like game thing and it was like 5,000 games. It was like the same game, but like the color palette was swapped. Yeah. And it was like, it's really only like six games, but they just like, they're like, oh, level two of Super Mario Brothers counts as a new game now. Yeah. We did approves all 3,000. I approved every single one of these guides. That's the thing is like we wanted a very curate, you know, we have playgrounds where it's user generated ones. But one of the things that we don't do is, you know, we don't do ads and we're not doing contests or anything like that. So what's happened in the like online tutorial guide spaces, a lot of companies, they're just built on doing deals with brands or whatever. So they're like, oh, enter, make a guide and that's your entry for a contest. So you just get a lot of stuff that just doesn't work, never was meant to work, a lot of copy and paste of. So this is the resource. When you buy hardware, this is what it supports. Pays all of our authors, pays the developers. And this is like what we, I mean, I don't know if they like spend a lot of money on, but it's like a lot of engineering time spent on the documentation and guides. It's really important. So learn.adaver.com, we're up to 3,000. Thank you so much, team. We'll play two videos that were in the learn system this week, but let's first talk about which guides. JP just published his project on automatic mechanical watch winder. He's just, he's coming off of his eight a box high. So we want to do like a project that wasn't, I don't see it too complicated, but it was like, you know, pretty straightforward and fun. And he has to think of a watch that needs, you know, automatic winding, but he's like, I'm not gonna buy some like expensive watch winding thing. So this is a motor that you put your watch on and it rotates and I don't know, it's like a good beginner project. We have from 3D Hangouts, the IoT battery monitor from knowing Pedro, they'll, we'll show the video about that, but it's a two piece part. It's like a two part project because you can use it to charge batteries. Like if you have a battery, you can use as a battery charger or if you have an IoT project that runs off a battery, you can use this to monitor it. And it just talks about like how to display it and send it to Adafruit IO and then use the new Blockly actions to tell you that, you know, your battery is charged or dead. Also have an update guide for the DPI display keep up because Bookworm and Raspberry Pi 5 has changed some of the instructions. And so Melissa did a refresh of that guide. So it's definitely gonna work on the Pi 5 and Bookworm. Erin did a massive project. We'll publish it, making an LED festival coat with this cool like seed LEDs and WLED, the magic story book guide also got a big update. Now it works with Bookworm, Raspberry Pi 5. We've got the guide for the two SHT Trinkies if you pick those up. And lastly, we have, this was the 3000th guide was the vintage computer to HDMI with Thunder DVI. This is actually really a really cool project. So it's a computer that has one bit video output like to, you know, RCA or whatever. And as in the Xerox 8200 and you know, not a lot of people have these old monitors. So we figured out like, oh, with the Raspberry Pi Pico, you can like bit bang read the image coming from the processor and then output it to DVI also using the Pico. So using like to, you know, all the PIOs, you're able to capture the monochrome data and then send it back out to HDMI. So it's like a custom HDMI converter for the Xerox 820, very neat stuff. Okay. And then the other thing is we have a couple of videos. So we're going to play those. This is the LED festival coat and then I'm also going to play the watch winder. No particular order. Your festival coat is about to get a serious upgrade. In this tutorial, I'll show you how to add animated LED lights to your favorite warmy. Use the Feather ESP32 and the free WLED software to create gorgeous animations that run inside the fur trim. That's the hallmark of any good festival coat. But this guide doesn't stop there. I'll also show you how to light up the body of your coat using a custom built mapped LED matrix. Run 2D animations like spirals, ripples and waves with just a few clicks on your phone. Check out the full build tutorial at learn.adafruit.com and remember to subscribe for more awesome costume projects. And we're going to do some factory footage and then some three printings you can see on the other side. Made in New York City factory footage. Okay, a little bit of a reminder, the coat is analog matrix. Also get free stuff in the store. Let's go over to some 3D printing. We're going to do this IoT battery project and then the 3D print in. Okay, then I'm gonna be I have to worry. Beat ups, then I'm gonna be I. Here we go. You can build an internet connected battery monitor for your Adafruit Feather ESP32 S2 reverse TFT using Adafruit AO and Circuit Python. The Feather ESP32 S2 with reverse TFT features a light poly battery charger and a Max 17048 monitor for checking the battery's voltage and state of charge. For many battery powered IoT projects, you may want to be alerted when the battery is charged or almost empty. You can use Adafruit IO actions to receive an SMS text or email notification. The battery's voltage and percentage is displayed on the Feathers built in color TFT. You can use the onboard buttons to cycle between an icon view or just plain text. The Circuit Python code checks the battery every minute and the graphics are updated with the voltage and charging percentage data on the TFT. The data can also be logged to an Adafruit IO feed for later analysis. To learn how to build this project, check out the guide at learn.adafruit.com. You can set up an Adafruit action to receive a custom email when the battery is fully charged or if it's nearly empty. You can also use this as a handy tool for folks who have multiple LiPo batteries and want to quickly check how full or empty they are. The enclosure is fully 3D printed and features a tray for housing a 1200 milliamp LiPo battery. The case also features an adjustable viewing angle so you can swivel it back and forth. We hope this inspires you to check out the Feather ESP32 S2 with reverse TFT and Circuit Python for your next IoT project. We're going to jump right in. I'm an API. I'm an API advertiser by DigiKey. And this week it's from Expressive. Lady, what is the new product introduction of the week this week? Okay, so this week, so normally I pick something from digikey.com slash new and this wasn't there, but I was personally interested in it. And this kind of a new product and we haven't covered a lot of Expressive chips. So I thought I'd show you guys what I've been looking at and studying recently, which is the ESP32 C6 new chip series from Expressive. You know them for the ESP32 and the ESP32 S2 and S3 and C3, well the C6, it's not actually like that new. It's actually been out for like a couple months, but one thing I've definitely learned about Expressive is it takes about like a year until the software and firmware support for their chips and modules to be like really solid. So if you're at all interested in doing stuff with Matter or Thread or ZigBee, now's the perfect time to pick up the C6 because it's been about a year and so the software is actually starting to firm up very nicely. So first up the ESP32 C6 is, you know, part of their Wi-Fi chip family. This one has Wi-Fi 6 support as well as your standard Wi-Fi, you know, every day 2.4 gigahertz. It also still has Bluetooth low energy. But the new thing that it's added is first up, instead of in 10 silica processor, it's using a RISC 5 processor, it's kind of cool. Starting to really see RISC 5 adaptation, I'm sorry, adaptation in companies, especially companies like Expressive that are based in Shanghai. And of course, the new thing is an 802.15.4 radio module which you can do, you know, ZigBee but also can do just straight packet communication with 802.15.4. And that's kind of interesting to me because, you know, all this also just shares one antenna which is like really nice. It's all 2.4 gigahertz, all sharing one antenna. That's the hard part of the engineering and they managed to do a really good job with it. It also is a super low power processor. It's kind of an update to the C3 which we've used. It definitely has more RAM which the C3 was a little bit lacking in. So it's kind of nice that they bumped it up to half a megabyte of SRAM. You do have an external flash chip but the module that I was showing earlier, that, you know, the one that, this is, you can buy the individual chip but they also come in modules ready to go with QSPI or flash memory inside of them. And so the module that we're talking about has four megabytes of flash. So far there's no PSRAM support. I don't think the chip maybe doesn't even support PSRAM. So it's not meant for like really big IoT like processing heavy applications. It's meant for low power, low cost, light applications but still want all the peripherals that you would want with an expressive. Also doesn't have as many pins as like the S2 or S3. It still has a lot but like just to let you know definitely has a little bit more than the ESP32 but less than the S2 and the S3. Okay, so like I mentioned, it still has the WiFi support you know and love. It's got the Bluetooth though energy does not have Bluetooth classic but it does have ZigBee and 802.15.4 like generic radio communication. And this makes it really good for use with Matter which is this new protocol. It's like a system of connecting IoT devices especially in home but also in industry that can use multiple different transports like WiFi, Bluetooth or 802.15.4 slash ZigBee but Matter is kind of like the new standard that everyone is going to agree on, hopefully. A lot of companies have signed on to it so like Google Home and Amazon will chat about AWS IoT and the latest products from Apple all support Matter which is meant to be like the easiest way to connect home automation devices. So if you are working in the IoT space you're making smart light bulb with a temperature sensors or whatever and historically you would have to have you know, a ZigBee or Bluetooth gateway you know when you use Matter if you see in the bottom the reason I picked this is what's nice about Matter is it can use any transport so 802.15.4 plus thread or ethernet or WiFi or Bluetooth and you can use Bluetooth or WiFi for Matter but like I said a lot of people are interested in using ZigBee because it's a low power, low overhead transport. If you're interested more about like you know the differences in when you want to use WiFi versus Bluetooth versus ZigBee slash 802.15.4 you know this guide that we wrote one of the 3000 guides we wrote this many years ago but it's still very relevant. We have a whole section on ZigBee at the time it was like often 900 megahertz because we were using like XBs and stuff but 2.4 gigahertz is really popular and you know there are existing non-Matter protocols within ZigBee that you could use with the ESP32C6 like the ZigBee Lightlink which is like supported by Phillips Hue and Family. So there are like profiles I'd call them with ZigBee but to be honest I think like most people are moving towards just using Matter. Farmers like I said you know you need a gateway so if you do go this route instead of BLE or WiFi you know it's very lightweight, it's very fast to connect. It goes fairly far but you do need a gateway so people are gonna you know and part of what I did today was try to figure out do I have a gateway? It turns out I don't. So you need like a Google home or you need an Echo or Echo Dot or you need a HomePod or HomePod Mini. So almost all these devices that people use for home on the voice home automation connectivity they'll have a gateway built in but you do need to have one. Turns out my HomePod is too old. Okay so one of the nice things though is you know you can pick and choose which protocol you wanna use based on your application or you know with your device it can change to the different protocols. So like if you are selling a device for example you may want to use ZigBee because say it's the lowest power, lowest overhead so longest battery life but if the home that it's being used in doesn't have a ZigBee router you could always fall back to Bluetooth or fall back to Wi-Fi and that's what's really nice about the chip supporting all three protocols. Also of course because it has Wi-Fi and BLE and ZigBee it can act as a bridge like in and of itself. So if you set up your device and it acts as a ZigBee router device it can also funnel other ZigBee devices to a Wi-Fi network if it's set up with the SSIDA password. Okay so the next thing is you're like okay this sounds great I wanna get in this this is the new hot thing, matter, it matters. You'll need to use the ESP SDK also known as the ESP IDF I think five is five two is the latest version. I'll say at this moment there's no Arduino support for programming matter so you'll have to use the bare SDK not that that's complicated I think you can use platform IO they also have instructions for every operating system but this is kind of like this is a CC++ path you're gonna have to make sure that you've got drivers if you've got your tool chain set up it's a lot of command line work another thing you could try which I did really fast is there is a zero code interface specifically for matter but it also I guess works for other stuff too that a specific setting up which is kind of neat cause I'm always into zero code writing so this INPI also is covering a little bit of this. So they have a lot of different ready to go profiles that you can use and as I was doing this I was like oh I wanted to use the GPIO plug just like indicate on off whatever and then realized that they don't have the individual support for the C6 yet in zero code they do for the C3 so the C6 must be coming soon however what you can do is if you're interested you can go through like their two chip solution which is called IoT express link from what I can tell basically you program the ESP32 C6 as your Wi-Fi slash Bluetooth slash Zigbee matter device and then you can communicate to it via actually can you go back one communicate through another microcontroller say you're you know SAM-D21 or your WinniSauce or your Raspberry Pi whatever and one of the nice things it also has a direct channel that it can send data to AWS IoT back in so you can use all the AWS like IoT capabilities that they've been developing over the last couple of years just kind of neat of course you know you'll have to have AWS account you'll have to pay for the services but it is a way to get your temperature or humidity data or your control straight into a dashboard through this partnership that Expressive has with AWS if you do want to do that you pick you know you can pick the module or the mini or the room the mini and the room have different pins select which one and then what's neat is that they're actually using web serial in a browser so you use a Chrome Chromium browser and then you can configure it I skipped over the configure page you can configure which pay which pin you want connected to like the LED or the temperature sensor whatever and then you upload the firmware directly from the console and it even generates the not shown here the certificate that you can use to do the deployment of the sensor and then there's a QR code that's tied to the identifier that's programmed into the device because it's like on the fly it compiled your firmware and configured it and it burned it into your ESP32-C6 over the USB port because it's got USB built in and then you can configure the matter device directly like I said after many hours turns out I do not actually have a matter gateway but I'm definitely gonna try this next because apparently this like just works out of the box and then you can use the AT command set through the USB port or the secondary serial port and you can see here like at the top in blue is what I said and so you say AT it says okay and then I mistyped some stuff you can say AT plus matter start and it'll actually like begin the matter protocol and you can set characteristics and get characteristics and set alerts and get alerts you can actually basically you have like a matter device that you can communicate with over AT commands which means you can use any micro controller or just your desktop computer if you want to experiment with it it's a very quick way to get started with matter and this like was amazing it worked out of the box which was kind of cool. So you can get dev boards you can get modules I suggest starting with the room module because it's cast-layed pads it's soldered to nice big onboard antenna there's also a version with a WFL antenna I think it's WFL not UFL so just watch out for that if you want external antenna and the best part is it's in stock you can buy it right now but that's right. Yeah a couple of questions since we're listening to friend someone know what have micro controllers just adopted 5 gigahertz I think pricing I think you know that with moving to 5 gigahertz you're gonna have to redo all of your analog front end and honestly I think Expressive really nailed down they're like Wi-Fi set up I think somebody once did a decapping and like analyzed the layout of their output stage for the Wi-Fi they're like oh my goodness this is like an amazingly engineered Wi-Fi analog you know the antenna front end and that part's hard and once you've kind of figured it out you sort of kind of don't mess with it I think that they will come out with 5 and like I think we covered IonMPI I think Nordic has a 5 gigahertz Wi-Fi module so you're gonna start seeing it come out but we're gonna still see a lot of 2.4 for the next couple All right and then with matter do you think we can have Adafruit IO hook up into it one day? I'm definitely interested right like that's one of the things I wanna try is you know we have this app that working on it's a snap and could it route matter device data to and from Adafruit IO you need an app to do it because I wouldn't want you have to have some way to do Wi-Fi or if you know I can figure out we would have the board be a Wi-Fi gateway I don't know how to do it yet but I think there's something there because I think there's gonna be a lot of very low cost matter sensors especially with the SB32C6 being an all in one ready to go chip definitely I see it being a popular chip to power this new generation of matter sensors for IoT And that's IonMPI IonMPI As folks noted, yeah the AT Command Center is still online and kicking speaking of Analog Matrix is a code to present off the native restore budget free stuff, let's do some new products Okay Coming soon Okay, speaking of the SB32C6 we have an ESP32C6 feather coming soon a couple of little things I might want to change around it but it's pretty much good to go so if you want to pick up this board that it'll be ready to use with matter sign up, we'll take sign ups I don't know exactly what's going to be in the shop when it's ready but sign up and it'll also let me know how many to manufacture for that first one Next up Okay, we've got from Electmix oh man I forgot their name we have the MicroBit Retro Arcade this is for your MicroBit V2 which has the NRF52 series does not work with the original sorry Electfreaks thank you not Electmix Electfreaks Retro Programming Arcade with the NRF52 on the V2 MicroBit the new version you can run Maycode Arcade on it when we love Maycode Arcade the only thing is that a MicroBit does not have a display it doesn't have enough buttons to do like arcade games this is a beautifully designed little shield even it got a battery pack so it's nice and safe doesn't use rechargeable batteries you plug the MicroBit into the top and you get your 180 by 160 color display you get six buttons you get JackDac which is their plug and play system for adding sensors it's got this nice curved round handholdable thing and the alligator clips are duplicated on the bottom so you can quickly add sensors I don't know I thought it was a really cute design but yeah a lot of people love MicroBit V2 but just I want to say it again you need the V2 will not work with the V1 the V1 is too slow to run Maycode Arcade next up okay next up we've got the Vivid Unit this is from UU Gear we stock a bunch of their Raspberry Pi stuff this is not Raspberry Pi based it's actually a rock chip micro computer on the back but it does have a Pi compatible-ish pin out so let's look at the back this is jam-packed and by the way I'm going to forget some of the things that are on this board it's got the rock chip 3399 core processor it's got a built-in speaker it's got two USB three ports it's got headphone out it's got speaker it's got SSD M2 NVMe built in so you don't need a separate NVMe thing HDMI camera connector looks like analog input Wi-Fi and Bluetooth onboard microphone onboard RTC battery connector your gigantic power supply look at that huge inductor in there those power supply Ethernet and the 2x20 character and then of course on the front beautiful I think it's 800 by 480 color pixel display so I think this is you know it's really cool what's neat is you can tell it's a tablet display that they've kind of recycled but like it's cool so this is just it showing I mean it's going to be tough to see because it's a TFT but it's a full capacitive type screen display so you can like open up applications you can open speedy operating system yeah it's very speedy I'll say I don't think I set up Wi-Fi on this yet but it's got all the stuff built in so it's kind of like I don't see it as a Raspberry Pi but it's the same similar kind of idea of a microcomputer but it's got a display ready to go so you can like easily mount this or use it with projects and it's running Linux so of course you can install Python on it you can run Python on hardware you can communicate GPIO you can get I2C sensors you can do quite a bit it's like a powerful all-in-one microcomputer basically that runs Linux so I think this is interesting it's definitely going to be more expensive than just a Raspberry Pi because it's got all that stuff built in but like you got a capacitive touch display and all the Ethernet and the Wi-Fi and the USB and the built-in speakers and the built-in NVMe I think if you added up all it would cost to put this all together on something like a Pi it would be more expensive so if you are using all that stuff as you get to go and I like that it like boots immediately you don't have to like burn an SD card or anything it's got onboard memory I guess to be honest I don't know how much look at the specs because I don't have it memorized yeah it's in the shop we have a couple if people like it will stock more next up next up this is an update to the MHP 30s MHP 50 which is a hot plate that you can use to do rework or reheating of small like a small electronic boards I'll say this came in today I didn't get to grab one otherwise I would show it off live if you remember the MHP 30 that's the reheat plate that I've been using it's 3 centimeter by 3 centimeter this is 5 by 5 so it's like twice as much also it can use DC or USB PD power it's 100 watts over USB 150 watts max over DC power so it heats up very quickly but you do need to get an external like laptop-ish USB PD power supply also the OLED has been updated to use a color TFT I think I'm going to definitely pick one up when we go to the shop tomorrow because if you have a I've had a larger board like a feather board I've had to kind of shove it around a little bit to make it fit on the MHP 30 but the 50 is basically the same price and bigger but you need a better power supply that's the thing so if you're using DC power you need a 24 volt power supply that can do 5 plus amps and if you're using USB PD you need a laptop power supply that can do 100 watts alright next up next up we have an RJ12 panel-mount extension cable this looks like Ethernet but it's not it's RJ12 also sometimes called RJ11 if it only has the 4 cables this is for telephony projects so if you're using telephone cable 6 contact cable RJ11, RJ12 this will definitely work well for you because you can panel-mount it what I like about these round panel-mount cables is you don't have to kind of square hole or like a weird oval hole and have drills you just cut one 30 millimeter round hole and up to I think a quarter inch or half inch material you screw the the nut off the back there is this you can see at the bottom there's a lug nut whatever it's a protection nut put the cable to the hole put the nut on the back screw it in and your golden and the lip covers up any imperfections in the hole too so this is kind of my favorite way of making panel-mount connectors so if you're using telephony cables this is the way to go alright I'm getting close to the story of the show not yet very close okay the ADG728 this is an I-squared C1-8 analog switch so I think we had analog switch a while ago that was like one to two you could like have the switch go like normally open normally close like a relay this is kind of an interesting chip from analog devices but it's like you know it's hard to get I-squared C-controllable analog switches and so I thought this was worth stocking so if you look at the front at the top there's eight pins labeled S1 through S8 and at the bottom at the bottom right there's a pin labeled D so the D pin can be connected to any of the S1 through S8 pins but here's the thing it's not like a multiplexer selector you could connect multiple pins to the D pin so it's like a matrix you can actually connect like S8 to S3 to D or S1 through S4 to D or all pins connect together so you can actually use it for merging signals not just for selecting a signal although I think a lot of people use it for selecting a signal you write the switches you want on via I-squared C it's break before it makes you don't have to worry about things accidentally getting connected if you set all the pins at once you either just write the 8-bit value and that whatever is a 1 it gets connected whatever is a 0 it's not there's two address pins just change the address and a reset if you want to like immediately set all the pins to be open so you know what would this be used for this isn't good for anything over 5 volts because it has to be the analog signal has to be less than has to be greater than grand less than the V in so it's good for like up to 3 or 5 volt signals so they're definitely good for analog analog audio signals because those are going to be like less than a volt if you want to move around audio signals this is definitely going to be the way to go you don't get any clicking like you would with a relay and of course it's instantaneous also could be used for some video signals could be used for signals into a DAC I've seen you know these kinds of switches used for the inputs and to you know op amps if you want to move signals around so this is very you know there's a lot of pins available 8 to 1 but basically this is kind of what was available the only other thing we had was a one way switch this is a 1 to 8 switch alright in the story of the switch besides you lady our team our customers everybody who makes this thing go is the ADG729 which is the sister of the ADG728 very similar but a little bit different so the ADG728 had 1 to 8 switch this has 1 to 4 switch twice so 2 switches so 2 sets of switches so you see at the top there's 1A through 4A and then 1B through 4B and at the bottom right there is there is the DA and DB pin so you can select any of the ACE pins to collect to the DA pin and any of the B pins any of the 4B pins to the DB pin so basically it's good for stereo analog signal switching so good for audio especially if you have stereo signals and you want to move them around because we use for video or like you know sensor reading or whatever and then don't forget it's not a selector you can connect multiple pins to the switch like each one has an individual switch so you can have all the switches on and that means there's 4 pins connected to the DA or DB pin so that'd be good if you wanted to merge signals together which you can do with this analog switch and then of course it's bi-directional too it's not like one way it's not like oh the signal only goes from DA to 4B or whatever or 4A it's bi-directional it's full analog it looks like a transparent 2.5 ohm connection between the switch pins and the DA or the DB pin it's also it's controllable over I squared C so like the 728 you write 8 bit value and that tells it which switches you want to have on you can have all them on all them on some of them on and then 2 address pins and the only thing it's missing compared to the 728 is the reset pin there's no reset pin because instead you have you know the 2 DA and DB pins so that's that's what got dropped in order to have the dual 1 to 4 switch so both are you know very similar and they use very similar code but one is a dual 1 to 4 and one is a single 1 to 8 analog switch both useful test it out alright well we had a couple of questions why not feel free to keep putting them in we're in discord we're gonna do some top secret then bounce the questions and we're gonna get out of here okay okay lady what's this okay I'm testing out these kind of interesting headers we got a request to have solderless headers in the store and so if you look these look just like pin headers you see there's like this little like notch hole in the shorter pin this the way this is designed is that you could kind of like shove it into some holes in a breakout board and they would make contact using like a cold contact not a hot solder contact so you could do some quick prototyping and then you could remove them if you wanted to but maybe you know for times when you don't want to solder headers in so the only thing I notice is that you need to you know kind of it's a little tricky you definitely want to have you know the headers the right length so let's break off piece and see if I can do this in my demo okay and then you want to get like a good grip on the header so I'm using like these pliers and then the pliers press down flat and there you go we did it and then I actually checked this is like solid and it's got continuity so the only trick is like you really need to use pliers or a vice to really get good leverage because you have to push them in but it's okay that this one is like not fully pushed in you can like give it a little bit more of a yank if you want there you go and then you just adjust it so you know it's not easier than soldering but you don't need a soldering iron anyways these look good so I'll put them in the shop alright lady okay I'm doing bring up on a new feather as you can see it's ESP32C6 this is a new chip in the family for Espressif it's a Tensilica processor sorry it's a RISC5 not a Tensilica processor and it has matter ZigBee support so I think it has Wi-Fi and I don't think it has BLE but it has ZigBee instead so I made a feather for this module it doesn't have a ton of pins so like one or two of these pins are shared for low power on the stomach QT port battery monitoring battery and recharging boot and reset button and you know plenty of analog pins, SPI I squared C UART and all that good stuff so I'm going to keep testing it but luckily because Espressif has like one board support package for all of their boards you know Neopix just worked out of the box so I'm going to test all the pins all the peripherals and then do some low power tests and then we're right leading to what's this OK I'm testing out the new camera PicoBell this is a board that matches up with a Raspberry Pi Pico or PicoW to give you access to parallel camera and an SD card and a shutter switch and a stomach QT port so this is how we used to wire up cameras for use with Pico so you can see on this like breadboard I've wired up all like 12 or 13 pins and then I've also wired up a 240 by 240 TFT and it does work but boy it is kind of a pain it's very messy and error prone so now with the new PicoBell it's much more elegant here I have a TFT but I've wired up a TFT separately you just plug it in and it uses any of the cameras that have the DDP interface which is like OV 7670 24640 5640 so I've got a whole bunch of things tested including taking photos and sending the SD card and of course mirroring and also a webcam demo so this is good to go we're going to get this into the shop soon and that is top secret okay let's do some questions yeah okay for questions a couple of them lined up and they already got answered in the chat okay but yeah it's okay yeah so for the previous product the question was what's the max bandwidth works with composite they check the data sheet bandwidth is 100 megahertz it's for my little devices guys they know what they're doing this is the good this is the good stuff okay the snapping headers are they okay to solder in and after you oh yeah you can definitely solder them in they're just like gold plate headers they're just like tough to put in yeah question is Aida for doing anything for the eclipse we're doing the best thing I think that any company does our team has tons of paytime off and a lot of people are taking off and going to the eclipse they're great one of the benefits of the company is people have great work life and great outside work lives so folks are doing their own thing it's we have some remote people and then we have people in New York and they're taking the time off and they're going to enjoy it with friends and family and more and that's what I think is the most important thing if it's an event like this where you can go somewhere so we live in a solar system that has eclipses and you're like that's so cool yeah it's weird I think because our moon it's an exact coincidence needs to be a certain size for it to cover the sun but you know if you have all these cosmic coincidences of course you're going to be like well that's weird because you're here yeah you know is it finally tuned just for us no but I don't think that has anything to do with like eclipses like there's some things like that water floats when it turns into ice it's like well if it didn't we'd be dead we wouldn't exist right but the eclipse I think is just a cosmic coincidence there's a lot of them it's a good one yeah it's a good one but it's also just a distance but the moon happens to be it's it's pretty weird let's see any other questions no this one they're just saying that they were doing some desodering so I need to do that and then just check over here I think we're going to call it because we're I'm dying I held it together we're all dying but like we're dying a little fast enough I held it together okay let's go again yeah we're kind of sick okay so we're going to we're going to go bye thanks everybody that's been our show don't forget to code is analog matrix thanks for joining us this Wednesday night you know you get the free stuff you get to code this has been an Adafruit production thanks everybody next week it's your moment of zener later
