 in downtown Manhattan, in the center of the universe, where we do all of the kidding manufacturing, shipping, coding, videoing, tutorializing, and more, it all happens here in the United States, all that advanced manufacturing. It's here, it's happening, and we've got a show for you about one hour of news and updates and videos and discount codes and more. We gotta get into it, because it's just so much going on. Mr. Ladyata, what's on tonight's show? All right, tonight the code is Makerverse, and that's because we had some special guests on show until we'll talk about that and more soon. 10% off in the Adafruit store, all the way up to 11.59 PM Eastern time, and if you're gonna go to Silicon, the Comic Con that's coming up, we have a discount code for that too, so multiple discounts tonight. Oh, multi, multi discounts. We're gonna talk about our live series of shows, including Show and Tell, which was epic tonight. Thank you everyone who came by. We've got everyone's favorite segment, chip shortage, because we can't get chips. It's analog devices this week, we'll talk about what we really want, what we ordered, and what we don't have. Advanced manufacturing, all the cool stuff that we do here in New York City, we make stuff. Some 3D printing projects and more. We've got IonMPI where we introduce a new product, brought to you by Digikey this week, it's from ST. Got some new products, we've got a little bit of top secret, gonna answer your questions. We do all the questions on discord, adafruit.it slash discord, we can join 35,000 of us, there's a lot of us there, and you can even hang out there after we're done broadcasting. There's a whole giant community that is showing and sharing their projects and more, so hang out. All that and more tonight on, you guessed it, ask an engineer. Oh, there's so much going on. So the code is Makerverse, but I just want to mention. What is a Makerverse? So, the Savage Makerverse is coming up at one of the biggest best events, the Silicon Valley premiere, Comic-Con, Returns. It has the best in pop culture, tech science, makers, artists, cosplay, gaming, comic creators, authors, and more. It's August 27th to 28th, and you can get tickets and you can go, it's the San Jose Convention Center. So there was the Adafruit discount code, that's for your store, but if you want to go to this event and save 15% off, use the code Adafruit. And because we live on the internet, and this is the way it works now, so we have nothing to do with this other than we're fans. They said, oh, here, we'll have a discount code for your community. We get no money, we're not compensated in any way. We really like this event and all the people that are doing it. That's how we roll. There's tons of things that we like and we put it on our blog. And there's things that we're like, hmm, that's interesting. We have nothing to do with any of this stuff all of the time. We honestly think it would be a fun event to go to. So that's our disclosure, is like, this is so cool. You couldn't pay us enough to promote it because we just think it's cool. So we did it for free. So anyways, use the code Adafruit. If you're going to siliconsj.com and you're gonna get tickets, tonight use makerverse on adafruit.com if you want to save some money on anything that you're buying at Adafruit store and we'll do some promotions and more. So anyways, I hope that makes the most sense. And then if you're shopping in the Adafruit store, we have a bunch of freebies. Freebies, we still have the $99 or more Promo Proto, hash size breadboard PCB, a colorful PCB, great for taking your solderless breadboard projects and making them permanent. We are still kicking it with the pink PCB. PCB stands for pink PCB. It's weird. It is a KB2040. It has an RP2040 microcontroller, dual core, 133 megahertz, eight megabytes of flash, stem and QT connector, cast-related pads. We designed it for people who want to use something that's a pro micro shape, but using the latest chip, the RP2040 and it's free when you get $149 or more in the store. $199, we've got free UPS ground shipping and still we have back the circuit playground express. It was out for a bit because we couldn't get some parts but then we got some parts and we immediately made circuit playground expresses with them, our favorite development platform, great for cosplay, great for making, great for learning, great for coding. It's got all the sensors and buttons and stuff built into it so you can start, get started without any soldering or tools. It's free when you order $299 or more from the Adafruit shop. Okay, and a reminder. So there is a giant global park shortage and there's also incredibly small supply of certain things like Raspberry Pis. So one of the things that we did, it's not only good security, but it's the way we manage folks not purchasing certain things and putting them on eBay for $500 is please make sure you make an account, you verify your email address and then you set up two factor authentication on your phone that keeps your account safe and secure and it allows us to limit the sales one per person for things like Raspberry Pis and that's just kind of the world we're living in right now. Believe me, if we could do it any other way, we would but this is the best way. Turns out it worked. This is how it works for us. Yeah, and the only people that are unhappy are the folks that were gouging one another for Raspberry Pis for $500, they would buy one and then they would put it on eBay or other places and that's not nice. That's not fair. That's right, we wanna make sure that all the makers and engineers and people attending stuff like Silicon get Raspberry Pis to make their projects. They shouldn't be $500, that was the whole point. 35 bucks. Okay, so we do a bunch of live shows. Today was an epic one, so that's why we're starting to ask an engineer a little later. On the show and tell, this week, we're trying to help get the word out with Adam Savage's Silicon. It's Silicon Valley's premier Comic-Con and it's back, Adam Savage and friends. So they stopped by and you can go to Silicon SJ and you can see the theme. It's creating the improbable and there's a lot of folks that you may know. Adam was there. Jen Schecter is there. Sophie showed up. There's people that are speaking at the event and doing workshops and more who you know. I'm James, we're about friends. Yeah, Kevin from Digi-Key, stop by. So there's a lot going on on the show and tell but we wanted to help out because there was a time and place where there was a maker fair every year and there was a time and place where there was a lot of things going on every year and if we all want this to come back and we want places for makers to build stuff like Sophie's doing to school, cyberpunk workshop, this in-person thing, these experiences that we can all have, we have to support events like this and we have to go there and we have to also figure out what things that we want to teach and share one day and this is the way to do it. So if you want, check it out. You can watch the show and tell and like I said, we have a discount code. And this is physical, in-person event. Yeah, and then you can watch the show and tell with all of the folks who stopped by but we also have a message from Adam. Hey everybody, Adam Savage here in my cave to tell you that silicon, well actually officially, Adam Savage's silicon is coming soon. It's weird to say it out loud. But it is Silicon Valley's own Comic Con. It is August 27th and 28th and in addition to a magnificent roster of awesome celebrities, we also have Makers Galore coming from all over the world. Some of my favorite and most admired colleagues are gonna be sharing their tips, tricks, techniques and stories with you. So we'll see you there. Okay, and then on Sundays, we do Descubilita. We do it in two parts. The first part is, usually when you're showing off stuff, what were you showing off this week? Well, this week I was showing off, I don't know if we mentioned there's this part shortage but there's a part shortage and so I've had to do a lot of redesigns. So for example, the CP 2104 is a chip that we've used in a lot of boards, no longer available. So I'm doing redesigns to change over to CP 2102, very similar that has required slightly different layout and parts. And one of the things that's happened is you know, it's one of those things where you're like, oh, I wanna just like dust something off and then before you know it, you're like completely cleaning out the entire room and like changing everything around. So I did a gut renovation basically on the Metro Mini, because I was like, oh, while I'm here, why not add a STEMI QT port? Why not go with a USB-C port? So I talk about all those changes and show off this design and also the sensor that I was testing. This is a very cool gas sensor called the AGS02MA that I was testing with the new Metro Mini. Okay. And then we also do a segment called the Great Search. Where's that part I need? Because it's so hard to find parts now. So what did you try to help people find this week on digikey.com? Well, what's funny is half the parts that we do on the Great Search are things that people send in, people are like, hey, can you help me find a part? And then one half are parts that I have to find. So this last week I had to find an alternative for the now discontinued fan 5333 and a really amazing 1.5 amp switch DC-DC boost converter that runs in constant current mode. It was a very good chip, no longer available. So tried to find something that's pin and size compatible, hopefully functionally compatible, found a couple options. One is closer in price and one is closer in functionality. So I might end up using both as I do some board respins. Okay. Show's coming up. Don't forget JP's product pick of the week that's coming up on Tuesday. You can watch the highlight this week. We're not gonna play all the highlights on the show because we did a bunch of show and tellin'. JP's workshop is tomorrow. Be sure to tune into that. And then triumphant return of Scott on Deep Dive this week. So tune into this at 2 p.m. Pacific, 5 p.m. and get the source. So it says Deep Dive with Tim but it's gonna be Deep Dive with Scott. Not Tim. That's right. The original host. So Scott will be fillin' in for Tim this week. So stop on by and say hi to Scott. All right, we're gonna kick it off with everyone's most feared and most favorite segment. Here we go. All right, this week's part shortage is analog devices. Ahead of what's possible is the tagline. Lady Aida. It's so ahead, I can't get it. What are we not able to get to make electronics this week? Okay, so this week the part I can't get is the AD8495. This is a K-type analog thermocouple front end and filter. It's actually kind of a cool chip because it converts a K-type thermocouple. It's like this is an eight M-stop part into an analog voltage. We have a bunch of max and parts that do digital K-type thermocouple or J, whatever, thermocouple readings. But what if you want an analog input? That's kind of cool. So we love this chip and people love it. You know, they really like our breakout. What do we use it in? We use the AD8495 breakout. So we can't make these. We cannot make these. And how many young people are not able to explore all of the things that they could experiment with and do with electronics? Like this is a top seller of ours. There's like 5,000 orphans that are crying in the dark tonight because they cannot do their high temperature data logging or people who are doing, also a lot of people who just want to make barbecue is really common for people who are making smokers, people who are making DIY coffee roasters, people who are doing counts. There's so many projects that use this. So, okay. So here it is on the analog devices site. Is it in stock at Digikey? Well, let's check out. So let's see. Do, do, do, do, do. Oh no, wait. Zero. This is our life. And like the lead time is like 80 weeks. So we did order these. We ordered 6,000 back in May of last year. And it's now pushed to November of this year. That's months away. So here's the thing. I'm not even sure we're gonna get it in November. This is a very estimate. So we would really like this. Miss analog, please, please, please allocate us some of these parts. There's an A type and a B type. I'll take either at this point. Please, please, please ship us a couple thousand of these 80, 80, 495s. It's- We did everything right. We ordered them over a year ago. We did everything. We ordered them, yeah, directly from analog too. We really want to make some of these. We really want- People want like the- The orphans are clawing at me daily. I cannot walk down the street. Everyone is just begging me for 80, 80, 495 breakout ports. Please, please, why would you do this to children? Why? All right. So that's this week's chip shortage. Looking forward to not playing that song one day. All right, so let's get off with some good news. It's Python on hardware time. Yay, Blinka. Yeah, we got a lot of stuff going on in the world of Python. Okay. Well, we hit a milestone. Yeah. 300 circuit Python libraries. From Adafruit, we also have, you know, almost 100 from the community and the community bundle. But Adafruit, us, we, whenever we do a breakout board, unless there's some really weird reason, we always do a library for it. Now sometimes there's stuff under NDA or there's a pre-compiled binary we can't, but pretty much 99% of our breakout boards and dev boards and sensors and helpers and libraries and stuff are part of the Adafruit circuit Python libraries. Here's the good news. Every circuit Python library we write is supported and also works in CPython, which means it works on a Raspberry Pi. It works on a computer with a USB GPIO converter, like an FT-232. If you learn Python once, you can use it in all these places. That's kind of the cool thing. The right ones run anywhere thing is actually possible now. With Python, also these libraries work on MicroPython if you use the Blinka library. So we hit 300. Thanks so much for everyone who helps. You know, all of these have documentation and typing data and read the docs and example codes. And it's just been awesome. You know, one of the best decisions I made was let's have one library that works for circuit Python and Python boards as well because people love to use our sensors with single board computers like Beaglebone, Raspberry Pi, as well as microcontrollers. Write once, run everywhere. Yeah, and if you want to support Adafruit and all of the folks that we pay to write all these libraries and more, pick up an electronic kit. Pick up a breakup board. Yep. Something at Adafruit.com and use the discount code tonight. Other news, we wanted to get out there speaking of support and others. GitHub sponsors now has more countries. So if you want to sponsor someone in another country, you can. Circuit Python Day is coming up pretty soon. It is Friday, August 19th. We have a lot going on. We have a panel discussion. We've got chat with some of the core team. We have a special edition of a circuit Python theme to show and tell. We have a project build. There's a lot of stuff going on. Fome Guy is doing a circuit Python day game jam stream. And then the thing that we're gonna show off, and then we have a ton of other things going on in the newsletter. A world of Python on hardware. Lots of videos. Unending projects and things that you can mix. Micropython. But I thought what we would do this week is show what came in the mail here. Oh, that's right. So this is from. So why don't you hold this up and then I'll get this all cleared off and ready. So this is. What it could it be? I wonder what it is. Well, this is actually a real unboxing. So thank you, Kevin, who sent this along. These are the hack tablets. Okay, so here's it. Oh, you have one. You may have seen the show and tell in the past. Where Kevin came on and Tim's show. Tim also went over this and said, we're giving these away. And the way we're giving you the way is, Kevin sent this to us. And we're gonna take care of all the shipping and everything. So here it is. Eight of your team and close is five. Quantity of the hack tablets in support of the circuit Python day giveaway coordinated with Tim Fomiga. Thank you for your support on this hack. Key match. So here, put that on the overhand. Look at this. I didn't know what was gonna be in this box. Like it could have been anything. It could have been like squirrels. And then here's the hack tablets. All right, so let's show one off. Yeah, why don't you open up one? You can use the... Okay, let's put it, yeah, go to the overhead and I'll carefully open one up. Yeah, you ready? Yep. Okay, let's do it. Okay, so take off my rubber band and then I'll just carefully open. Well, we wrap this one complete. Okay, so this is, uses a Creston display and enclosure and then we'll unwrap this. Okay, ooh. Okay, so this got a ESP32S3N8R8, which means it's got eight megabytes of flash, eight megabytes of PSRAM and it needs that because this is plugged in and controls a seven inch capacitive touch display. There's also, okay, there's, ooh, there's a little thing. Welcome to hack tablet. This is using Circuit Python. They're gonna try to get into the main branch. Kmatch signed it. This is genuine. It's in color. And then maybe I can just quickly plug it in. I don't know if it's gonna work, but you know what, I'm gonna risk it. I guess, only question is, I don't know how to, I'm learning to, but maybe I can just plug it into here. I don't know. Do you think maybe? I didn't expect that we would be powering it up though. Yeah, I don't either. So I'm sorry if I do something wrong. Well, lit up. Something's happening. Something's happening. Oh, ooh. Whoa. Look at that. As you can tell, we completely didn't plan this. Look at this. This is great. So someone is definitely gonna get one of these for sure. Yeah, I don't think the touchscreen does any. Oh, it does. If I can, whoa, that's kind of fun. Yeah, that cool. All right, yeah, this is super fun. So do you want one of these? Yes, and you can get it for free, right? Circuit Python Day is one we'll be giving these away. So, that's what you want. Circuit Python Day. All right, thank you so much Kmatch and Fome Guy for getting the word out on these and thank you to the Circuit Python community that's making all this possible together. And that is this week's Python On Hardware. Don't forget, you can get this newsletter delivered every single week to your inbox. You can also look at it on the website if you don't want to do that. And it's at Adita for Daily. We made a completely separate site because we don't want anything connected to your store account because we don't like spam either. We don't spam you anywhere, but this made it super duper clear this is completely separate just for newsletter. Okay, I got to put this carefully back. That's right. That out-of-the-box demo with the hack tablet was better than my first iPod. My first iPod didn't work out of the box. Good work, Kmatch. Okay, let's do some open source hardware news. We have 2,708 guides in the Adita for Learning system. This week, what's on the big board, Lady Aida? Yes, how about I give this to you? We're sort of safe because I'm the clumsy one. This week we've got from Liz Clark, a really cool circuit python, USB MIDI to CV, one volt per octave Skull Helper. Basically, if you have a synthesizer, you're a rack that takes one volt per octave and a long input, but you want to control it for MIDI or you want to like do some arpeggiation or you want to do some filtering, what have you? This little tool will use a QT Pi, which is my controller with USB, and then you connect a 12-bit DAC to it and it will generate your one volt per octave. So how handy is that? And it's skull shaped. So I don't know if we have a little video, we'll show the one minute video. We do have a video that we're gonna show at the end. Okay, we've also got from JP, he's got a little tutorial on how to use motorized, slider pots, also known as motorized faders. He's got some circuit python code, the Arduino code's coming, but basically if you're like, okay, I've got this motorized potentiometer fader from Adafruit, how do I actually use it? There's a capacitive touch, there's the changing the location, how do I get it to move to a particular location? He's got some example code to get you going. So check that out, it's a great little guide and he'll be doing some fun projects with these motorized faders. We've also been updating some of our guides, the SCD 30 guide and the DPS 310 guide. I think these were both added to the whipper snapper sensor quick starts. So if you wanna use these with our IoT service, with no coding, no soldering, these sensors are supported and now have documentation, thanks to Eva. Okay, next up on the big board. Next up, Catney also wrote a tutorial on using the PCF 8574, that's last week's new, two weeks ago, a new product. It's a GPIO expander, eight bits that works over I squared C and she's written a guide that has all the schematics and diagrams, Arduino and circuit Python or Python code. We've also got the Raspberry Pi face recognition treasure box. This was a massive guide, like overhaul by Paint Your Dragon. This is one of our most popular guides. It says Abigail, but Abigail actually did the helping and moving it from our old system to the new one. It's actually originally written by Tony D and now updated by Paint Your Dragon. It uses a Raspberry Pi and Eigenface, OpenCV to do face recognition and only open the box when the original owner's face shows up. So it's a good demo of machine learning, vision using the camera and it was originally written for the Raspberry Pi one so you do not need a Pi four for this. It was designed for a lower power Pi, which is great because it's kinda hard to get some of the newer ones now. Andrew Sink who has a great webpage for low polyifying 3D models. We've got a guide. That's an ASCII thing, where you upload an STL file and it makes cool ASCII art. That's cool. Yeah, so fantastic 3D digital artists that we had. We're gonna guide with us. It's 3D Scan Week here. Yes. So it coincidentally, these both came at the same time but they're two different ways of doing it. So there's both information and both guides. So Andrew Sink, we wanted to throw some caches away to help promote his projects. So we did that by having him write a guide and how to do 3D scanning and then use his tools to make a low poly model. And then Noah and Pedro also did a guide. They went out and did some statues and they also showed how to make them into a lamp with some neopixels as well. So if you wanna make some cool low poly versions or you don't have to low poly them but I like the low poly style. But just using photography to make 3D models, you don't need a LiDAR, you don't need a special phone. Almost any phone can do it these days using online tools. All right, and here's that video. Hi. What do you wanna do? I was just saying, can you please come back to me after? Cause usually we jump straight into the 3D. I do wanna shout out also if you want to buy, if you want to make one of these MIDI to one volt octave devices but you don't wanna go through 3D printing and building there at Stargirl at Winterbloom makes a module that does this as well that also runs Circuit Python. I wanna shout out to her cause she's inspiration for this project. Right on. All right, let's do some factory photo chair. And it wouldn't be made in New York City for us right now unless Disney was making a building across the street. So it's continuing to grow. It was windy out and it was raining so you can kinda see some things at some of the upper floors. I can see the little guy and like the cherry picker, hey. Yeah. There was a question in the chat when a board goes through one pick and place machine, does it assemble it in one machine and then part of it in the other? Yeah. For that board in particular because it's all LEDs. So what we do is we have each pick and place has a certain number of nozzles. And so we load that many nozzles versus reals on both. And so cause it's all LEDs and they take so long. Like a board with 144 LEDs, it's like you can imagine there's a lot on LEDs. And then what we do is we run the job through a computer that will tell us the most optimized way to load balance across the machines. So usually what happens is you eventually have so many reals and you have one machine. One of our machines is faster than the other too. So we'll optimize. Basically one of the pick and place machines is kind of like a NeoPixel machine. And then the other one will be things like chunky GPS modules and stuff. And it's totally like the traveling salesman problem. But in a robot, like this is actually it. You're like, why am I learning about this theoretical graph solving optimization issue? This is it. This is it. This is the one. Okay, let's do some 3D printing. Okay, we're gonna show the video of the low poly sculpture project and then a speedup. Here I wanted to show this. So this was from the Rubin Museum. It was a Buddha sculpture. And it's beautiful. It's a person. It's this giant Zen master that's meditating. But the aesthetic that I like is this pixelated look. So I used my phone. I scanned it. And you can print these out. We have these. Well it's kind of minimalist, right? Yeah. It's like the Japanese Zen Buddhist style. Yeah, and it's really beautiful and you can light these up. And one of the neat things is you go to a museum and you see sculptures. If you bring your phone with you, you can scan it and make your own little miniature ones. And you don't have to even print a big one. Here's a little Buddha, see? All right. And so we wanted to show how to do this in a couple different ways. So no, Pedro showed to make these type of sculptures using all these open source tools. And then we had the original author of this online tool. Andrew, he also did a guide. So this is a 3D scanning week here at Adafruit. So we'll play those videos back to back and see you on the other side. Hey, what's up folks? In this project we're scanning statues to 3D print low polygon miniatures. You can 3D scan statues from museums, art galleries or historical sites to make custom keepsakes. With an Adafruit cutie pie and a Neopixel stick, you can make them glow to make a custom lamp. To diffuse the LEDs, you can 3D print them with zero infill to make them hollow. Using photogrammetry, we can generate detailed 3D scans and use a low polygon generator to make artistic renditions. Use the Polycam app and take about 50 photos of a statue at different angles. Even with differences in lighting, distance and people walking in front of the statue, you can get a pretty decent scan. After Polycam processes the photos, you can export an OPJ file to clean and modify. We imported the file into Blender and removed the unwanted geometry. We'll start by adding a box around the part that we'd like to remove. Next, we'll add a boolean modifier and use the box to isolate the statue. Switch to edit mode to select any leftover faces and delete. Check out the guide on the Adafruit learning system for full step-by-step tutorial. To generate a low polygon model, we used Andrew Sink's low polygon generator that you can find on lowpoly3d.xyz. Here, you can easily decimate the model to get a cool-looking low-res statue. Next, we'll export our model and then re-import it into Blender to fix any overlapping faces or overhangs. Inside Blender, we can delete extra faces and fill in any holes generated during the low polygon process. Then, we'll use the fill face command to rebuild the geometry. To fix any extreme overhangs, we can pull faces by going into the sculpt mode. We use the elastic deform tool to help pull faces so they're at a 45-degree angle. This will help cut down on the amount of support material. Now, we can export the model as an STL and slice for 3D printing. We had a lot of fun printing these and think it's a great way to experience works of art when you aren't physically able to travel. It's also great for archiving. Being able to touch and feel objects that are protected from the public is a great use of this technique. We hope this inspires you to try 3D scanning and make your own. Thanks for watching and be sure to subscribe for more projects from Adafruit. And don't forget you can watch 3D Hangouts with no Pedro on Wednesdays at 11 a.m. Let's kick it off with some IonMPI. MPI. This week's IonMPI is from ST. Ladyida, what is your new product introduction of the week brought to you by Digikey? Okay, I'm glad you asked. What is it? It's the STLPS-28. This is a new barometric pressure and temperature sensor available from ST. It comes in this funky package. It's got this like cool lip on it because it's actually designed so you could put into injection molded case with an O-ring or you can attach a tube to it and have, again, an O-ring maybe to seal it. The thing that's really cool about the sensor is it is a dual full scale up to 4,000 hectopascals, absolute digital output and it's water resistant. So this is neat because we've had a couple of water resistant packages that are like, okay, you just can use them outside and they're not likely to get damaged, especially if you're using it to measure outdoor humidity. I like, you know, without a Teflon coating, these have like a gel coating. The iSquad C, they have 24 bit reading, but really the thing that's cool about them is that they go to 4,000 HPA. They are part of a family, you know, we stock actually quite a few ST barometers, pressure sensors. I think we stock the LPS-22, the 25 and the 33, so you can see some of these, but as you can tell, you know, pretty much all of them, except for the 28, only go up to 1260 HPA, which is, you know, basically sea level. Sea level is about 1,000. One atmosphere is about 1,000 hectopascals and so that's what you'll usually see for most sensors from SD, from Bosch, from other vendors, Sincere and et cetera. So what's interesting about, oh, sorry, and then here's some of the other sensors. So if you do want to pick some of those up, you know, we have some of them in stock as well. And they're good for altitude sensing. So this is what, you know, a lot of pressure sensors are used for. Yes, you can use them to kind of detect weather patterns, but what they're most commonly used for is, you know, as you go up a mountain, as you go upstairs or as your drone, you know, lifts off the ground, the pressure's going to change and you can use this to detect changes in altitude. But what a lot of them can't do is go below sea level. So one thing that this sensor does, which was really nice is it's got, you know, it's got that MEMS sensor in the middle and the ASIC is what does the I-Squared Sea conversion. And the metal lid is, you know, mechanical protection, but then it's filled with gel and so the gel protects it from water pressure up to 10 atmospheres, which would be 10,000 hectopascals and keeps it water resistant so you could actually dunk this under water. Of course, you know, the rest of the circuitry has to be water protected or sealed, but the sensor itself can be exposed to water and it even says, you know, water can be mixed with some chlorine or detergent or solvents or chemicals to some extent. I think if you have like a, you know, I wouldn't dunk it in gasoline, but if it's just water that has some contaminants in it, the gel will protect the sensor and allow you to still sense that pressure change. And it's important that it can do up to 4,000 hectopascals, also known as about four bar, because if you wanna use a say in a diving watch that can go down to 30 meters or just, you know, a watch that can survive under water usage and tell you how far below you're going, how far below the surface of the water you are. You know, it's interesting is, you know, most sensors, I think they are like, you know, a couple hundred to again 1,000 hectopascals and that will actually take you up to like, you know, most mountain tops, but if you go only down 10 meters under water, the pressure doubles at 20 meters, it doubles again 30 meters. Now it's three times, sorry, four times as much pressure as you would at sea level. So, you know, even though it's like, wow, four times the pressure reading, that must mean you can go infinitely deep. Nope, 30 meters, but that's still very deep. And of course, you could use this as a sensor to determine if you're making like a UAV that goes under water or some other underwater robotic cam or something that could be in a high pressure zone, this sensor will do the job. And of course, it's waterproof as well. The interface is nice and convenient. It's standard I-squared-C, there's an interrupt data ready pan handy, there's an address select pan, so you can have two sensors or maybe actually four sensors, I think if you connect the SA-0 pan to like power ground, clock or data, I think you could have a couple different I-squared-C, address seven bit addresses. And then it's also not only I-squared-C, but I-3C, which we covered a couple shows ago. It's, you know, the new modern I-squared-C improvement has a couple of things going for it, but back compatible with I-squared-C. So don't worry, you can still use it with your 8-bit microcontroller and then you want to integrate this into an Android running watch with I-3C. Go for it, you're also good to go. Another nice thing I noticed is the register map is really simple. There's a built-in calibration, but the calibration is programmed at the factory. So you just, once you initialize it, you set up what FIFOs or whatever you want or how many readings to take before doing any kind of averaging. You pretty much just read the pressure out as a scale from zero to the max value, whether you're in high pressure or low pressure mode. And that's it, there's no math, there's no exponentials, there's no logarithmic stuff you gotta do. It's really easy to get that data out and calculate it instantly. ST has a library, if you don't want to write it from scratch, check it out, it's not Arduino, but it could probably be easily ported to whatever platform you're using. Of course, it's gonna work great with ST's IDE and tools, but it's on GitHub, so check it out. I really am enjoying that Silicon vendors are now releasing published open source code for their drivers, for their sensors. It's a big step up from even like a decade ago when you were really on your own, you read the data sheet and good luck. But having it not under NDA being open sourced and available is awesome, so check that out. There's also an eval board, which I can show on the overhead real fast if you want to get started quickly. Didjiki has the eval board in stock and it's basically just a simple breakout. Yeah, well, and then here it is. We like to do these when you can actually buy them. Yes, so this sensor is actually available. You can purchase it. So it's not part of the chip shortage, it's part of NPI. You wouldn't do that to you. No, so this is, let me see. So this is the sensor in the middle there. So this is just a simple breakout. I think this one plugs into some of their dev boards, but you've just got the iSquirt C pins labeled out here in the interrupt ground power and just a capacitor, that's all you need. And you can see it's a quite small sensor. It's designed for watches and wearables, but of course it can be used for anything that needs high pressure, waterproof sensing. Okay, and that's Ion MPI. Hi, Ion MPI. All right, we're gonna remind you, this is the code for our store tonight, Maker Burst, but don't forget, you can also, if you're thinking of going to Silicon, coming up with Adam Savage, Maker Burst, which we talked about all throughout, this is our disclaimer, we just trying to help out, get the word out. But if you want to, there's the code Adafruit there too. And we'll have some reminders on all our social media platforms later. Let's do some new products, I do. Let's do it. New new songs this week. New, new, new, sorry. The new song is, oh my goodness, there's so much going on that I am, I can't handle all the news. All right, so let's kick it off. There's like, I'm putting like, I usually have a minute before the MPI. There's a lot going on this week. New product. Okay, so let's kick it off. Okay, starting off, we have this like 30 in one DC adapter kit, and we do have a couple of DC adapters. Because basically all the power supplies have 2.1 millimeter inner diameter, 5.5 millimeter outer diameter plugs, you know, our nine volt adapter, five volt, 12 volt adjustable, et cetera, et cetera. But people are like, I want to use this with some weird ass device with a weird ass connector. Okay, this is it. This is the weird ass adapter party. 30 adapters, some are weirder than others. I can show them off quickly. I just want to show people how they work, because basically each one of them has a 2.1 millimeter DC jack plug. You have your standard wall adapter that we sell. Again, the most common sizing is 2.1 millimeter inner diameter. You plug it in, and now it is a different plug. So let's say you're like, I have a weird Lenovo, or Dell, I think this is Lenovo, rectangular laptop connector, and you want to plug it in. Okay, only thing is of course the adapters, the adapters do not do any voltage conversion. They don't do any polarity conversion. So they all assume that you have a center positive adapter, because again, that's like 99% of things are center positive. Not good for if you're doing something with, like there's some audio devices and pedals that you center negative. So basically you get just a ridiculous number of like, what is this? I don't know, it's some other laptop. This is like a Dell inspiration thing, who knows. This is like Sony and Lenovo. Plugs, plugs, plugs, you've got stuff. And some of these are like a total nightmare, like this one is like a phono jack. Like I've not seen this, I've seen like your power goes through a 2.5-millimeter phono, it's totally cursed. You know, 1.1 millimeter in-ear diameter, all sorts of weird ass ones. I have so many things where I'm like, I'm never gonna find the power adapter, I'm gonna need this now. Yeah, so I'm taking this home, because there's always like, and like they all look really similar, but they're slightly different sizes. My sharp Zara's PDA will finally get charged up. So yeah, so there you go, you get a whole bunch. So we recommend, there's two ways I recommend. One, use our DC power adapters. We have again a adjustable one, you can dial in the voltage, when you need 19 volts or 17 volts or six and a half or whatever. We also have our USB Type-C PD adapter. So you plug into a standard USB-C power supply and it gives you again a 2.1 millimeter. But then you're like, okay, I have to actually convert it to my laptop. So you wanna basically turn your laptop into a USB-C powered device. And it's using one of these crazy, ridiculous plugs. You can then do that. So 2.1 millimeter, don't forget, doesn't change the polarity, doesn't change the voltage, it just changes the plug. Okay, and are the connectors labeled as to size? They are not labeled on the plugs themselves, but on the website we have a list of every single size. But it's pretty much all of them. All right, what's next? Next up we've got a bunch of servo helper cables. This is a shrouded servo to basically triple, like separated triple header plugs. So you're like, why can't I just use plain headers? You can use plain jumpers for this, but it's really nice if you look at the socket. It's got that little notch cutout, which means you can't plug in your servo backwards. So it's kind of good for kids. And workshops on the end, the pins are separated. And what this means is if I bring my demo, that's the song is bring my demo. I run the overhead, I'll show really fast. You can take your servo, you plug it into the adapter, and then it splits apart. So if you're plugging into something like a servo, you're not doing the little game of like, how do I, which cables are connected? You just have all the colors and you have five ground in whatever your signal line, and then your servo is going back and forth. That's cool. We also have a version with alligator clips. Right. Same sort of thing. Alligator clips separated out to a nice servo plug. Again, you're like, why can't you use jumper cables alligator? Well, it's got this nice, like it's shrouded and it's like the white orientation. And then show this version on the overhead. I know there's so many new products. You have a micro bit, you have a circuit playground expressed, you have some wearable thing. You want to connect a servo. You don't have to worry about mixing up pins or anything. Everything is like labeled and ready to go. So it makes it very easy to connect any standard servo. Just plug it straight through. And you add a little more length. Good. Next up, more cable adapters. This is a JSTXH extender. JSTXH is our 2.5 millimeter pitch. They look like this. They're often used in arcade connectors or buttons or anything that has an LED that's connected to a wire. It's a pretty, we have JSTSH extenders and stuff, but XH is also used, like I said, especially for arcade buttons and micro switches. It's a very common connector. So this gives you a bit of stretch. Okay. A little bit of a follow up from some of the things we were showing off last week. We've got more colors of these. These step switches, like the TR-808, we have the other video, of course, it also covers these. They have a single pole double throw switch. They have a beautiful clicky connector and we've got the multiple colors with a red LED. So again, often used in like step sequencers in the 80s, but I think it'd be pretty cool for some projects you want to build now. They do work, JP report, they worked in Perf board. Things are on a 0.1 inch boundary, but they're not easily used in a breadboard where there's lines for each row. They're best used in like a gridded proto board where you can kind of free wire them. But you get a couple per pack and multiple colors, red LED, a great little input, and they're very, very clicky. Yes, you can check out the page there. And we also are doing more these potentiometer knobs. Yes, we've got these micro knobs. Sometimes referred to as Davies 1900 style. I've also got a beautiful demo with a potentiometer, rotary encoder. What's nice is that they all have set screws. And so whether you have round D shaft or T18, doesn't matter. It'll work with any kind of six millimeter-ish knob. So we've got brown, purple, and green, and I think we actually even put in blue like right before the show. But it was just fine. We have all the colors. And don't forget, we also have a rainbow pack, if you see down in the corner. We have a pack with one of each color. So if you're like, I don't know which one I want, get the rainbow pack and I'll get you one of each. And then you can decide if you want the four packs of other knobs. Okay, and the star of the show tonight besides you, Lady Aida, our community, our staff, our customers, is a product that grew in and from the community. Congratulations, Joey. Joey has a product in our store. It's a feather wing. It's the star of the show this week. Can you distract people? Because I left a demo on my desk. Can I distract people? I can always distract people. Okay, so my distraction will be, so this print that we did of the Buddha scan, this one has a zero infill, so it's hollow. This is a resin print. It's heavy. It's a good distraction. Okay, so let's start from the beginning. The star of the show tonight besides you, Lady Aida, our community, our customers and our staff and all the folks who purchase things at Aida Fruit is this. LCD feather wing. Joey, congratulations. Yes, he made a product. He kitted it. He sold it. We bought some. So this is a feather wing specifically for adding a really fun LCD display. He made a custom LCD display and apparently he didn't talk about it too, which is cool. He made a custom made LCD. This just demo shows it flashing. All these are individually controllable, but I'm just flashing them on or off. There's like a moon. There's an alarm. There's like a wireless signal. There's like data transfer. There's a battery, AMPM. And then of course you can see multiple digits here. Not everything is lit up, but there's like another digit. There's a colon as well. You can see there's decimal dots. So it's got lots of segments. Oh, and a negative sign back here. You can see that isn't lit yet. So I just have it set up with the Circuit Python demo, which just sort of blinks a couple of things and then increments the time with the colon dots. What's neat is that this uses a, let me plug this here. It uses an I squared C, a very fine pitch. I squared C to LCD converter. So all of that like controlling of segments and like the timing and all that is taken care of for you. You just have this chip. You connect over I squared C even has the instructions and this bear, I think. I don't, I think it's a bear with like some sort of robotic leg and it's got a reset button and you can change I squared C pins. You can change the address. And then the custom LCD, which is like exactly the right size. You can make a clock, a calculator, bandwidth detector, all sorts of cool stuff, whatever you'd like. And it works with Circuit Python, although I think they'll probably be in Arduino library eventually for people who want that. I'm using that on a Feather M4, but it'll work on any Feather device with I squared C, which is basically all of them. We'll work with this design. And our receiving team said that Joey's kids that came in were the best package. Everything was complete. Everything was perfect. Out of every vendor, we've had thousands of them. Congratulations, Joey. That is high praise from our team. All right, so pick it up. That's the speaking promise. Okay, cool. We're gonna do a top secret and while we're doing the top secret, don't forget, make a verse, is the code for our store. Adafruit is a code on Silicon SJ if you want to go to that event and hang out with Adam Savage, Jen, Jen, Sophie, Jay, and this year's theme. Digi-Key. Yeah. And this year's theme is creating the improbable. So we're gonna do some top secret. Yeah, we got the top secret video. So go over to Discord and start posting your questions. I have a couple lined up, but we're gonna do some top secret, then we'll bounce over to the questions. Here we go. All right, this week's top secret. We did a little video and we're just gonna play it because we have a bunch of screens on the way. Okay, lady, what was this? Hey, everybody. We're here at the Adafruit factory where we do all our manufacturing and today I'm testing out some TFT samples. So we get these raw TFT panels from factories and sometimes we evaluate new TFT samples and new factories. In this case, we've got two versions, very similar looking of a five inch TFT display with a touch screen. And so what we like to do is we load the sample in and we make sure that the touchscreen part's working and that it's colorful and the contrast is good and the backlight works. And if it's good, then we can have it as an alternative supplier and we test with a single board computer. So it's very easy to set it up and then put it away when done. And so far, I actually really like this sample a little bit more than the TFT currently use. So we'll probably end up transitioning to using the slightly brighter looking TFT. That's weeks, words are starting to fall out of my head. That's this week's top secret. We'll have more next week, but let's go over to the questions, lady. Let's hit up some questions. Okay, so the questions this week, as far as unobtainium, which is things you can't get, Jets and Nanos, we don't stock those. Yeah, we don't stock them anyways. Some of the hardware locator, Twitter sites that the chat posted, sign up for those. We're more focused on Raspberry Pi stuff. So that's what we've been trying to manage this supply of, but there are some Jets, Nanos, Jets and Nanos, they're just on other sites. Because the BNO55 is unobtainium, but 085s are available. I'm planning to send my 085 circuit Python library to simulate some of the 055 methods. If so, do you think the community would be interested in sharing the person making this? I will say we actually did, I think we did put some BNO055s in the store and I think we might have a couple more in stock left. So if you just need a couple, we do have some and I think we also shipped some out to DigiKey and Mauser of our breakout. So, you will be able to get them. That said, it's always a good idea to make sure that your library can do either because just because we have some this week does not mean we'll have some next week. Okay, I can answer this one, I think. Hi, I'm new to this community. I have a little knowledge of electronics but I'm learning, I have a project in mind and have been to the Adafruit site, I'm having a hard time narrowing down the board I need. Is there somewhere on the site or this form where you could point me in the direction that would help me narrow this down what I need? Yes, so there's a couple places you can go. Of course, you're in Discord right now so save the project you're doing and if it needs Wi-Fi or if it needs battery or if it needs things the team will or the community will say, oh, here's a board you can look at. You can also go to circuitpython.org slash downloads and we have filters on the features of specific boards. And even though it says Circuit Python, you know, there's our stuff supports, Arduino and all that stuff but that's a good way to do it. You can also look of course on our website but that's where we stock a lot of stuff so that's a little bit harder. So you might want to check out the Make Board Guide. What a great idea. They're coming up with the next one soon, the 2022 one but the last year one, 2021 is available and just go to any search engine you want and type in Make Magazine, Digikey Board Guide or Make Magazine Board Guide and you'll be able to use their interactive viewer. But if you type in what project you're doing we'd be able to help you out and just say, oh, like what are you trying to make? And here's a board that you can use. Yeah, it's really hard because we have so many breakouts and so many dipboards and some we carry just because people use older projects so they're not the new stuff but we don't want to discontinue them because we try not to discontinue. Some of the latest and greatest but sometimes the latest and greatest is so latest and greatest it's a little tough for years. We also have a guide, thank you Mark for putting this up in the chat. It's on the Learn site, it's called Chooser Circuit Python Board. That's a good guide too. But usually, you know, it's like, if I want Bluetooth, here's a series of boards. I want Wi-Fi, here's a series of boards. I want both, here's a series of boards. Oh, I want to make sure it has battery on board or a screen, here's a series of boards. And so that's kind of a way to start thinking about it. It might, that's not the answer, it's just how to get to the answer. Yeah. Question for the show. Is the 804APDS9960 going to be okay to sense if a red LED is illuminated with color detection or is the board better for seeing reflection of an item? Yes, it can detect LED. Yeah, I mean, light coming off of something that's illuminated or red light hitting it will both be great for detecting color. Whoops, I must skip this, but I did not. Can the step switch have the LED changed to a different color? Not easily. Not easily. And they only really come in red. So I pretty much went with red. Okay, here is the question about the board. We might have some suggestions. I want to use a motion sensor that will send a signal either to my phone or my Google Nest Hub and needs to run on battery. And, but I would like to use a solar panel to keep it charged. I think it's a good one actually for the forums because there's going to be a couple of questions, what kind of motion sensor and how you're expecting to send it to Nest. So that's, the solar panel stuff is easy, but it's like getting that data that can use if this and that. I think we need to get- It might need to be a board that works with Adafruit I.O. Cause then you have to use it then this, that and then you can use Nest. So that, that'll be- I don't want to, I don't want to say like, get this and that. And then it's like, oh shoot, but you're using go-to. But you're getting closer to what we'd be able to, or the community- This is a great thing for the forums. We answer questions like this all the time. Yeah. Okay. I think that is it. Cause we got a bounce. I think that's going to be all the questions. It was jam-packed. We've been in this chair for 90 minutes. Yes. We've been here for a long time. So that's our show for tonight. Thank you everybody. Don't forget the code is makerverse. That's on Adafruit.com. And then if you are planning to go to Silicon S.J., don't forget, use the code Adafruit. That'll be going all the way until the event I think. And you get 15% off. So please consider it. And like I said, we get nothing for doing this. We just think this is a cool event with a lot of people we know. So that's why we're helping out. Turns out we like things and we like to share. What is that? My moral of the story of tonight is, you know, we like to make things and share. And even if it's just a news article or a book or a movie or code, the more you give, the more you get. And because we like sharing things like code and how to make things, Joey has a beautiful series of tweets. And I can't believe I just said beautiful series of tweets in a sentence because normally those things aren't true. But it's a good example of when you share and you give, it doesn't diminish you in any way. It just makes everything brighter. It's like the whole like, you can light another candle with a candle. It doesn't make the original candle any dimmer. You can light more together. So I think it's really neat that you can use even a platform to get the word out about an event. You can say, oh, here's a cool movie or a cool song I heard. Here's all sorts of things. What's the sense of holding it in? Because you never know what's gonna spark the next person. So I think that's kind of neat and that's the theme and that's why we're really happy to see all of our friends who are running Silicon and friends we haven't met in person yet. And all the people that are gonna go to an event like that and years later, they're gonna say, It's gonna be so much fun. I'm very jealous. That's when I got my start. Or, you know, someone like Joey is like, oh, he was posting today, he's like, here's my first kit that I bought from Adafruit. It was like 2018 or something like that. And now he's a manufacturer of electronics. And everyone talks about like, well, how do we have manufacturing come back? Or how do we do this or how do we do that? Well, action and sharing seems to be a really good way. So anyways, thanks everybody for coming by tonight. It's very much appreciated and we'll see everybody next week. Special thanks to Zay behind the scenes. Also thanks to K-Match who sent the awesome hack tablets. These are really cool. And a cool demo. Yeah. They worked. And really nice package. And you know, normally I open up boxes before we do something because I'm like, well, what if something... Who knows what's gonna be in the box? But that worked out really well. And special thanks to everyone who's been helping out in the chats during tonight's show and more. And thanks for your patience because we had a very long show until, but I think it was worth it. So we'll see everybody next week. This has been an Adafruit production. Here is your moment of Xenor. We'll see you next week, everybody.
