 Live from New York, it's Wonder Woman. Now it's Ask an Engineer. I got my Gauntlets of Truth, I don't know. Yeah, Lasso of Truth. Lasso of Truth was the Gauntlets of what? Gauntlets of Bullet Deflection. Bing, bing, bing. Do you have a name now? Bing, bing, bing. Just Gauntlets, huh? Yeah. Okay. Welcome to Ask an Engineer. It's me, Lady Ada, the engineer. With me, Mr. Lady Ada on camera control. Hello. Behind the scenes, videography, sound, and more. We're broadcasting live from the Adafruit headquarters in downtown Manhattan. That's behind us. This is where we do all our kitting and manufacturing and shipping and packing and videoing and coding and more. Everything happens here, but right now the factory is asleep and I'm a little burpy. The factory is asleep because everyone is at home. They're done for the day. It's just us, Mr. Lady Ada and myself. And we're going to kick it off with about one hour of the latest in burping, news, electronics, making, hacking, crafting, coding, and more. Todd Butt said Gauntlets of Ristness, which I think is... Gauntlets of Ristness, okay. Yeah. Oh, no, sorry. GP said Gauntlets of Ristness. And Todd Butt said Gauntlets of Sotter Mask. Gauntlets of Sotter Mask. Yeah. I like that. It's pretty good. Gauntlets of Sotter. Gauntlets of the Great Search. Yeah. All right. On tonight's show, the code is Micropot. 10% of an Adafruit store all the way up to 159. PM Eastern Time gets you 10% off in the store. All the things that we have in stock usually lose it. It's tonight only. We have a bunch of live series of shows, including Show & Tell, which just happened a few moments ago. We'll talk about that. Time travel, look around the world, makers, hackers, artists, engineers, and more. Chip shortage, it's back because it's never ending. It's a chip shortage every day and every way. This week's chip shortage will be from Toshiba. We'll do from the mailbag letters from you to us. We've got some advanced manufacturing made in New York City, factory footage and more. We've got some 3D printing. We've got IonMPI. This week's is Renaissance. And wait until you see this cool video. If you liked last week's video, you're going to like this one even more. New products, a bunch of top secret. We're going to answer your questions. We do that over on Discord. Adafruit.it slash Discord. We were 34,000 people. Now we're 35,000 people. It's a big old community. Come on by all that and more on, you guessed it. Ask an engineer. Yay. All right. So the code is micropots. It is not a dispensary that is opening up down the street. It's just the name of the code. What is this? Weed for ants? Yeah. Because we have a lot of these. We'll talk about that later. But that's why. That's the reason. We have a lot of code. But when people order stuff, they get free stuff. We have freebies. And we're back to having our quad freebie collection. It's actually a good sign. It means we're able to get some parts back in stock. $99 and more. We get a free permaporto, half-sized breadboard. Great for taking your breadboard project. Use our premium breadboards, which people are loving, and making them permanent. $149 or more. You get a KB2040. I love this little breakout. I use it for developing all sorts of libraries and code because it's got lots of pins. It's cast-related. It's got a STEMIQT port. It's got an RP2040, which is a chip you can get, and USB-C. So what do you not love about this? I don't know. It's even in pink. Everyone loves pink. $199 or more. You get free UPS ground shipping in the Continental United States. It's trackable and insured. And back, not just because of popular demand. That's not enough. We also have to have the parts to make it. And we got some parts. We've got the Circuit Playground Express, our all-in-one dev board that we love so much. It's got a SAMD21, which we were able to get. Tons of sensors, buttons, piezo switches, capacitive touch, tons of Neopixels. And it works with Arduino, code.org, CS Discoveries, MakeCode, and, of course, CircuitPython. OK. And don't forget, if you're going to order stuff on Adafruit, just a good idea in general for all the sites you use. But in particular, Adafruit, because we offer this, do two-step authentication. So you make an account on adafruit.com, you verify your email, and then you set up two-step authentication. That'll allow you to buy things like Raspberry Pis, which we do limit to verified accounts that have two-step auth turned on. OK. Adafruit Live, series of shows. We do a bunch, including Show & Tell. Thanks so much, JP. JP hosted the Show & Tell this week. I got a chance to glance by it really fast, so I'm going to watch all of it. You all can do that, too, and get all the highlights and more. I'm Pedro next week, and then the week after that will be Liz, and then after that Melissa's going to try hosting. So we're mixing it up, come by, and then I think one of the weeks, some folks from Hackaday are going to stop by, and then we invited some of the folks from Makerverse, Adam Savage and his team, who's doing the Silicon event in August. So we'll see. We have a bunch of folks that are going to come on the show and tell that we're scheduling up. So look forward to that. On Sundays, we do, from the Desk of Lady, it goes in two parts. This week, we showed some things that we were working on, events and more, but what was the part one? OK. So part one, we showed off the 3D model. I'm going to show that later in the show, too. Yeah, the model of the van. I also talked about, I'm designing some cowbells. So talked about some of the process with that. And also a desombification of the Easy Link and Easy Key board that I've not been able to manufacture because I couldn't get modules. I'm going to try to redesign it with an ESP32. However, here's the deal, folks. Do not ask me every week when it's coming out because I don't know. We have to write all the code all over again. Yeah. I will get it out as soon as I can. You know what's interesting is how this works out, because this is how I have a high surface area with requests and stuff. And I know it's hard, but here's what I try to think about. I notice people just love this stuff. Well, it's also so everyone doesn't get together and share the information that they've asked. So for each person, it's new and helpful. It's true. It's one of the 10,000 people a day who are learning about the Easy Key for the first time. Yeah. But I really do. We are working on it, but we have to port all the code all over again. Yeah. And so I think the analogy I could best think of, imagine if your name was Michael Bolton. Oh, like the singer? Yeah. And even though everyone doesn't get together and do that and know that they've already asked that question. Has anyone told you that there's a singer? Are you a fan? This is an office space comedy thing. But I think you get the point. And so sometimes, especially now, we get asked a lot, when is this going to be back in stock? When are you going to have this? When are you going to redesign that? And it's a bunch. But we know that y'all have best intentions. And the folks who don't will politely say, like, please don't be so mean when you ask. Yeah. OK. It's true. Please be nice when you ask. We also do this segment called The Great Search. How can I get that part I need? Because I can't get the parts I need anymore. Yeah. We're going to extend the name of the title. What was this week's Great Search? OK. This Great Search is, as I'm working on these cowbells, I needed a new microSD card slot because the microSD card that I use, the colder that I use for a lot of our boards, is just like two millimeters too wide. And so I went on the hunt for a slim, skinny microSD card holder that's not our hinge type. I wanted a push-pull type. And I like the one that's used on the Teen C3.6. So I kind of looked to see if I could find something that's just like that. Yeah. Again, Desk of Lady Aida. We'll have a bunch of things. And I think we're going to show something really cool. So someone said a good trick to do is when people say, when will something be back in stock just say next Tuesday? Or just Tuesday, but just don't say what, Tuesday? Oh, like on Tuesday? Yeah. But I think we're going to have a fun thing for Desk of Lady Aida. Always tomorrow. OK. JP's product pick of the week. That's the show that we do inside of a product page each week. And here's this week's highlight. NAU7802 24-bit ADC. I'm going to take a clue and plug that in. I'm using some crimp connectors connected up to a load cell. Looks a lot like this one, except this one I have mounted to a little metal plate. And I've added a little place to set something that you're weighing. So I will take a container. And now I'm going to tear this scale. I'm going to hold the button there. It's going to remove the weight that it sees on there from the starting point. So now we're at zero. I'll start pouring these in. And you'll see that the weight is going up and up. I went a little over. I'll pull some out of there. OK, watch this. I'm going to put one bean in. And you can see it's really precise measurement that went up to 18.1 from 18. It is the NAU7802 24-bit ADC for measuring strain gauges and load cells. OK. And then don't forget, on Thursdays, we have JP's workshop, including the segment, Circuit Python Parsec. I learned from. That's right. And then on Fridays, we have Deep Dive with Tim, a funny guy. And I'll talk about this during the Python on Hardware section. But do tune in leading up to Circuit Python Day, which is Friday, August 19. It's a company holiday here at Adafruit. And it's a worldwide celebration that we do online and more about all the things going on in the world of Circuit Python and the community. And we're giving away some tablets. Thank you, K-March and Tim, for helping out. They're on their way. And I'll talk about this. And Tim will talk about this. I have a little segment in the upcoming newsletter section. But tune in, because you can find out how to get one of these. These are really cool. All right. Time travel. OK. So I went to Hope, Hackers of Planet Earth. This was at St. John's University. The team at 2600 did an amazing job. St. John's University was an excellent venue. It was safe. It was good to get together. It's been a really long time. I have a couple of photos. I always ask people if it's OK. If I took photos, or if I was in a session, or something like that. So I'm waiting to hear back from some folks. But I do have some things I can share right now. So as you entered the venue, the 2600 van, famous van, was out there. This is a 1981 Dodge van. And it's in all the photos for every hacker van and maker fare and everything. And this year I decided, this van ain't going to last forever. Or at some point it should be put in a museum. It's supposed to look like a bell phone truck. These are iconic. I don't even know what people know in England. Yeah. Some people are like, what is this? Niners. And so what I did is I used my phone. And I did a 3D scan of it. And I think this is the first time it's been 3D scanned. So you can see, I got a good scan of it with the phone tools I have. I was able to take enough photos so I could do some interesting things later. But the idea is making a 3D printed one or one of those like diecast ones. And I just wanted to get all the details right. So I emailed Emmanuel and Kyle who are the folks who I hang out with there and who run 2600 and hope. And we'll see. So I'll keep you all updated. This is a fun little art project. I want to do kind of preserving this interesting thing. There's a free Kevin sticker on it. This is a really neat piece of hacker history. And I was also thinking, so Lady A and I walk around New York City and sometimes we'll come up with these little word puzzles. Like, oh, like all things that have huts, like sunglass hut, pizza hut, Jabba the hut kind of counts, but not really. And one of the ones I think we should come up with when we walk around this weekend is hacker cars or hacker vehicles. Oh, hacker vehicles. That's a good one. Yeah. So Mudge is like Camaro. That's one. That's literally a hacker's car. Yeah. But a hacker's car, kind of famous enough, but like the 2600 van is one. And then any movie that has a hacker in it, roller blades, that's not really a vehicle, but like kind of sort of, you know, there's like hacker transportation. Yeah. So anyways, I'll leave it to the chat. So anyways, I took some photos. You know, this has been around for decades. Yeah, there was some cat shaped hardware. We saw some folks that were doing some cool circuit Python stuff. The boost, they had these really neat folks that were from the local New York area. FSF was there. You've got a bunch of folks that do books. EFF was there. Our friends Amy and Ariel from Sparkle Lab electronics. No starch press, one of the best publishers for all things maker related. And certainly they have kind of the best hacker crypto books and more. They also have like really neat Python books as well. So they were there. And then there was some nerds helping, nerds in time of need. This is Operation Hammond. I stopped by and saw them. And then I think this was the thing that we helped out with because they needed a Raspberry Pi really bad. It was this like wireless, like location game thing. It was a hope in real life. And then of course, hardware hacking area, ham radios. I got to see Mitch who have not seen in three years. So I'll be seeing Mitch in person again later, but we were able to, I talked to Mitch online, but I haven't seen him in person in a really long time. So it was really good to see Mitch. And then Bea from Girls Who Hack stopped by Adafruit right before that. So all in all, it was really good. And again, congrats to everyone at Hope who did a fantastic event. And boy, it's been a crazy last couple of years. Okay. A little reminder for Adabox. It's gone from winter to spring to summer. And it'll probably be summer fall edition. We're chipping away, getting all the parts we can. It's happening, but we're not going to bug you with an email until we know a date. So if you have any questions, you can always email our team. We update adabox.com. And of course, we don't charge cards and all that until we ship. So thank you everyone who's been patient because you all know what it's like. And then the other thing and the reminder, and I'll do this during the other segment with the Circuit Python and MicroPython and Python on Hardware News is on August 19th. This year we're doing Circuit Python Day. So don't forget about that. All right. Well, that's all the good news. And then here's the reality bucket. The only thing everyone likes about the chip shortage is that song. But it is a great song. Thank you. Very catchy. Willie in the chat. So this week, Toshiba, we need a bunch of these. Hey, Toshiba. What are these? Hook us up with some TB6612s. Yeah. So this is them, huh? Yes. We have many thousands in order. I think we ordered them back. Oh. We ordered 18,000 of these back in December, 2021. It's pretty much August. We still need 6,000. Yeah. Please ship us some. So this is from our internal system. And what are they used in at Atofer? We use them in a lot of our motor shields and motor feather wings and motor drivers. And we sell a lot of these people love these motor drivers. They're great for steppers, for DC motors. The TB6612s are great because they have built-in diodes, kickback diodes. I think they have a max current of two amps. They're really reliable. You can PWM them. They're overall just awesome DC and or stepper motor driver chips. I went to the site and it's like purchased, but like that's just messing with me. You go to the Digi-Key site and as you can imagine, you're in stock. There's none. This is life. I know. But maybe Mrs. Tashiba can hook us up. Yeah. And I know you're not supposed to like want and desire things because that's suffering, but you know, we ordered these. I would like that. Well, our customers would. And this is to help people build cool, fun robots. Yeah. We're using these for good. These are not being used to hurt anybody. This is for the youngins. No kittens are being crushed to death by these motors. They're only the happiest motors. Tashiba, we'll drop you a note. We'll send you a link. We respect you. You know we respect you, but we just have a bunch that we order and we just want those. Please. We order a year's worth at a time. Yeah. We plan this. We do order ahead of time. We can advance. We do everything. Please. So that is this week's chip shortage. We really need them. Thanks so much. Please, Mr. Tashiba, can you please send them? We'd really appreciate it. Thank you. That's chip shortage. Okay. So that was the chip shortage news. Let's continue to go through the multiverse. We'll change the channel and go to where there's some excellent vibes coming our way. Because you know what's available? Send in great emails to us. That's not at a shortage. So we get your letters. Lots and lots of letters. So this week, this is from the mail bag. These are the emails that folks send us. I absolutely love your packaging list or packing list. I know what a strange thing to say, but seriously, you have the best packing list ever. Color picture of the items, part numbers in bold and blue and larger font. Love, love, love it. So one of the things that we like to do is also put quotes on there. So if you ever go to Adafruit.com, you can see all of our quotes that we have that go into the invoices and those come from people in the community. So they're inspirational. There are things that are hopefully will inspire you. Maybe it'll make you think about sharing with one another or thinking about that person who helped you so you can help someone. So there's a lot of cool quotes like that. It's Python on hardware time. All right. So this week in the newsletter, we have a circuit Python 7 update. 732 has a bunch of bug fixes. Yes. Dan Hubbard has been actually fixing a lot of issues with airlift boards and libraries and just cranking through a bunch of stuff. So even though we are working on eight, which is has a lot to do with Wi-Fi and workflow and adding ESP 32 support. We are still keeping up to date with 7.3 series and of course will all of those changes will be in eight as well. So if you're up for it, please use eight. But we definitely recommend if you're still on seven to upgrade to 732, particularly if you're using airlift boards. Yeah. So we noted that we hit our latest milestone and Discord. Thank you everybody. We have about almost 5000 people there at any time and then all together 35,000 people. Our Discord is a little different than other Discord for folks who are multiple servers. So our goal isn't to have like 35,000 people all there at once. And I know like Discord will give you a certain perks if you're a community or server or brand or company. If you have like massive amounts of people at the same time. What we usually have is people who come in for help showing their projects and then they go and make stuff. So we don't have others. Yeah. So we don't have as many of the Discord perks that they give you, but we do have a lot of members. We just don't have them all at the same time, but we still have quite a bit. So anyways, if you're wondering like why we don't have all the same flare buttons and stuff like that. There's a panel inside of Discord that says you need to have like for the number of people you have, you have to have more people on at the same time. And I've tried to explain this to Discord that we're a little different, but I get it. Like we're unusual for how we use things. We always kind of use things and maybe how they're not intended, but that's why we're all here. So anyways, tons of projects and more. I thought there was a pretty neat entry in the newsletter and did a post and also put it in there. It's like, how do you steer all of Python? So there's an article about... The big projects. Yeah, there's an article. It's like, how does it actually work? What does the steering committee do? What does the Python software foundation do? What's the benevolent dictator role in the past? You know, all those things. So check out all the different stories and more. All the things that we do every single week. That's nice. No motor. A little blink of a snake. Yeah, that's nice graphic. She wants a TB6612. Yeah, lots of e-ink and badges and more. And then Joey's been kind of like doing a real time thing with like, here's how I do drivers with Circuit Python. So all that being said, the thing that I'm really excited about is Circuit Python Day, which is August 19th. Kevin, up in about a month. And this is from Kmatch. And these are the Circuit Python powered tablets. And we're given away. And here is a note from Tim. Hello, everybody. Foamy Guy here. Today, I'm excited to share the details for the Circuit Python hack tablet giveaway. There are links to this announcement and the entry form in the description below. To summarize, you may now enter to win an ESP32S3 powered hack tablet using the entry form linked below. On August 3rd, we will select the first three individuals to receive tablets, giving priority to those willing to help test or develop this functionality for two out of those three tablets. On August 26th, we will select two more individuals to receive the remaining tablets. Everyone who didn't get chosen on the third will be automatically entered, along with anyone who submits an entry form prior to the 26th of August. Thank you for watching. And special thanks to Kmatch for making this giveaway possible. That's kind of a big deal. We're going to have Circuit Python powered tablets that we're going to send out to some folks. Then recycle, toss out stuff. Yeah. So there was a question in chat. We'll bundle this up into the Python on hardware section, because I think it's interesting from your point of view, Ladiata, because you're one of many people who work on Circuit Python. But when do we decide to do something like, oh, Circuit Python 732 is solid enough. When do we say it's time for 8? Well, 8's being worked on right now. The question is when 8's ready. And the answer is when we have enough people who've used it, given us feedback, and we've finished up the bug list. We have a bunch of issues and bugs tagged in Circuit Python. People who are beta testing open them. And also we find them. And also there's stuff that we want to get finished in development. We'd like to get an alpha or something or a release candidate or a beta out Circuit Python day. So the thing that you can do to help is try out 8, alpha, whatever we call it, mainline, latest release, and let us know what doesn't work so that we can fix it. And then I'll get us closer and closer to the release. Just like maybe in your experience seeing other open source projects or even our work with Circuit Python, do you think it's an amount of time where we're like, oh, 7 is stable. Let's start experimenting with 8. Or is it like a combination of two? We want people to break 8 because we have a bunch of changes. Is it time? Is it use? It's both. We do major releases when we have major changes. So for example, I think the MPY format might be changing because we keep upstream with MicroPython, right? So when they make a big breaking change or something that really changes the experience, that's a major revision. Otherwise we just keep using the version we're on right now. For 8, we're adding this Wi-Fi workflow. It's a pretty big change. We're adding ESP32. It's a different way of using Circuit Python board. It's a new family of chips. And so for that, we wanted to go in at this MPY change. There's a couple other breaking changes, I think. So what we tried to do is if we remove something, that kind of goes into a major revision as well. So that's how we know when to move from 7 to 8. Yeah. And then let me go to adafruit.com. For folks that are super fans, so we don't have a lot of these. So that's why we're not putting in a new product section, but I'll put this in the Python on Hardware section. So if you scroll down because this was a coming soon product, you will notice... Did I pass it? No, I didn't. Okay. There's only 14 left, but we have Circuit Python 8 posters because we tried to make sure we have posters for the team. And this one, we got special permission from Espressive to do a Circuit Python launch poster. So there's only 14 left. And that's probably going to be it. Yeah, we don't make more. Yeah, probably going to be it. So if you were wondering when 8 is going to be out, usually a poster happens and then a few things happen later. And that's this week's Python on Hardware. Don't forget you can get this delivered to your inbox every week. It's a completely separate site because we don't believe in spamming or anything like that. And that's this week's Python on Hardware, lady. Okay. All right, lady. We're an open source hardware company. It's true. And to prove it, we do a bunch of guides. Let's go to our new guides. Yeah, and this week, because I was really busy, I didn't put the graphic in the same way. We're going to do it a little bit different. We're going to just go to the learn system. Yeah, I will say there's a lot of updated guides. There's a lot of updated guides, anyways. So what happened is that we realized that some of the newer feather guides were missing the power management page. And we also have a new templating system. And so Katani and Eva have been going through and updating all of our feather guides to have a consistent power management page, which is like 99% the same from product to product. So you'll see all those feathers, all these feathers are getting updated. There's basically the power management page, which actually shouldn't look any different. Also, there's the fun house and the mag tag. Here's some of the newer ones. Okay, so what get updated? So go back up one. Yeah, these are... Okay, so no, go back down. No, stop. Go down. Like one row. Go down one row. You want this row? One more row. One more row. Great. Thank you. A little driver. Yeah. Take a left. Take a right. That's our exit. Okay, so the SD9.com will break out. So this got updated thanks to Liz. The reason it got updated is the LSM6DS33 plus List3MDL breakout is no more. We can't get the DS33, so we have the DS3 instead. And so we've just updated this guide to indicate the new breakout that we're using in the sensor. All the tutorial on how to use it with the 9DOF is now updated. So thank you, Liz. Liz also did an IoT food scale with Azure and CircuitPython. We're doing a bit of a partnership with Microsoft and Azure because CircuitPython is a really, really great way to do microcontroller IoT projects. You've got a repel. You've got error messages. You've got lots of drivers. You've got string handling, like a lot of stuff that's really hard to do with C or C++ or Arduino is really easy with CircuitPython. And we want to show how we can make little devices that can connect to Azure for making prototyping or building fairly complicated interface. A lot of folks, they'll learn with CircuitPython with Adafruit.io with Whipper Snapper. And then they're like, oh, I have like a really large project, really a big industrial project, a really big, heavy project that needs servers. Azure is big. And so that's why we said, well, we don't want Adafruit.io to be that. And what we'll do is we'll show folks how to learn things with CircuitPython, with Adafruit.io, with Whipper Snapper. And then when you're ready, here's the bridge to something like Azure. And we show, like, if you've learned this here, here's how to go to the next thing. There's also, there's a lot to learn. So I practiced using Azure before we did this project because I was like, well, I have to make sure that this is something that we can do. And what's interesting is, you know, Azure is pretty intense, right? It does a lot. And I feel like when you're working on something like a new service that you want to integrate with, like Azure, there's also so much to learn that you want the hardware to not be a problem because there is always that initial problem of, like, you've got the hardware, you've got your sensors, and then you have to connect to the service. And, like, you've got, like, six unknowns going on here. And with CircuitPython, we really, we tried really hard to take away a lot of the unknowns. You make the debugging of the hardware side a lot easier. And so you can learn the Azure software side. The next project, we'll use a single board computer as well. We're working on that, that guy next. But, you know, how can, how can you learn how to use this very advanced IoT system? And whether or not you actually use CircuitPython in production, you at least can get a feel for, like, well, how can I interface with stuff? How do I use the digital twin stuff and the alerts? You know, electronics expert to do stuff with Azure. That's the approach. It's kind of like how our philosophy, I think, with, like, even robotics, it's like you shouldn't have to know everything about power to do robotics because, like, that's a separate skill set. You should be working on, like, getting things moving and, you know, having a robot do something. Not just, like, I need to study batteries for 10 years, anyways. So, next up. Okay, next time there's more feather guides updated and then next, a mega guide. I'll go back up. You want me to go this way? Yeah. QMK on the RP2040. Yes, it's true. You can now use QMK, which is the, like, most popular keyboard firmware system for open hardware in the world. It has been ported to the RP2040. It's still in the develop branch. It's not mainline yet, which means that in this tutorial we show you how to install, like, the compiler set up and you have to build the firmware. We do have some pre-built firmware for you for, like, the MacroPad, but just be aware. It's in development and hopefully the next month or two it'll move into the mainline and then you'll be able to use the configurator tools online to create, like, custom key maps, but for now you have to get to do it by hand. Still, if you're interested in using QMK on the RP2040, it is now possible and we have a guide to do it. Good work, Jeff. Thank you for the LSM6DS3 TR plus 3MDL. That's that nine-dof sensor we talked about. And then, again, some more feather guides got some power updates, but I think that's it. This is all, I think, from last week. Yeah, and we have 2,706 guides right now, plus a lot of updates. A lot. I know we're doing a lot of updates, but it's good. I like to go through. We go through the feedbacks and, you know, we do the best we can with keeping the guides up to date. And because everyone was so good and you listened to us pontificate about IoT devices and more, you get a cat video. You can track your pet's food consumption over time with this IoT scale project using Microsoft Azure and CircuitPython. The project uses an Adafruit QDPi ESP32-S2 which has built-in Wi-Fi and a stem-up port for connecting sensors over I2C. The scale is built with a strain gauge and an NAU-7802 stem-up board. The strain gauge is mounted so that it measures the torque being applied from the weight of the food container. With the press of a button, you can send the current way to Azure or modify CircuitPython code to send at certain times of the day. Tracking Inventory is a great use case for an IoT project. Using Azure's charts and data line capabilities, you can see usage trends over time and even create text and email alerts when inventory gets low. See how you can build your own by checking out www.adafruit.com Alright, now it's time for some advanced manufacturing here at Adafruit. It wouldn't be New York City factory footage without the giant shadow of the mouse growing across the street. This is the Disney building. Mega Mouse. I noticed that the Orville is now on Disney Plus. I had to ask someone the other day. I was like, I guess they own it now. I was asking someone the other day. I was like, oh, I heard that new Teenage Mutant Ninja Turtle Game Shredder was cool. And they're like, yeah, it was a good game. I'm like, wait a second, does Disney also own Teenage Mutant Ninja Turtles? And none of us knew. Like, who owns it? I don't know. Did they? Eventually? Maybe? Who knows? Yes? All of it? Some of it? Soon? Who knows? Okay. 3D printing. Alright. NoPager are off this week. So, no 3D printing. Just kidding. It's a good video. Next week, NoPager will be back for 3D Hangouts and expect all sorts of goodness and 3D printing and learning how to make all this stuff and more. Some breaking news from the chat. Paramount owns Teenage Mutant Ninja Turtles and Paramount has their own streaming service for now. Good to know. Yeah. That's who owns them. Good to know. IonMPI. This week's IonMPI is from Renaissance brought to you by DigiKey and Adafruit. What is this week's new product introduction? It's great. It's from Renaissance which we've only done once before so I do like to highlight a bunch of different companies. Renaissance is a massive multinational but originally Japanese company and they make a whole bunch of products so when this popped up, this sensor you know me, I love sensors. This is the FS-1015 it is an air flow velocity sensor. It comes in this package. I'll show it on the overhead later but there's basically a slot in the sensor. It's kind of an all-in-one module. There's a slot and you can blow air through it up to 15 meters per second which I looked up it's 30 miles per hour and it will generate a signal for you and allow you to measure it. This is a cool sensor because it uses solid-state MEMS thermotransfer techniques which I don't know about this principle but apparently this is what it uses and it seems to work quite well. It's coated, even though this is designed for air, it could probably be used for other gases and you don't have to worry about corrosion or clogging. Most flow sensors that we've seen water flow sensors in particular use an impeller like this where it's hooked up to a Hall Effect Sensor when air or water flows through the little fan spins around and you can do the counts and then you convert the counts into meters per second or overall flow rate for wind speed. Of course folks are familiar with anemometers or these are sometimes used at airports but also people have them on top of their houses sometimes or their traditional farmhouses or like a booster with one of these rotating cups and by counting the speed of the rotation you can calculate wind speed. This sensor is of course much smaller and doesn't have mechanical parts which is great. It's like one less thing that you have to worry about possibly breaking. And this is part of a series of sensors so if you're like hey this is a cool air flow sensor but what if I want to do liquid sensing there's also the FS20 or 1012 which is Orenasos owns IDT Integrated Date Technologies and they made a version that had these barb prong tubing connectors so that it can be used for liquid, same overall deal, same kind of sensor but those sensors I believe are analog only but they do basically use the same functionality so this is the version of the liquid sensors. Yeah so this is a just to indicate for people also stocked by Tijiki they have quite a few of these in stock. The FS1012 is used for liquid sensing so check that out if this is not quite what you want you want something fluid not gaseous. But this is a sensor so what I thought was really interesting about this sensor is often times sensors like these just give you kind of a weird analog output or they give you a resistive output then you have to set up a bridge or some current sensing or whatever and you need an op amp and all this wiring but what was really neat is this sensor when I saw the pinout I loved it because you have power and ground and I think it's 3 to 5 volts power and ground. There's an analog output which will show next and then there's I squared C output so it's like really handy because a lot of you know microcomputers these days if you want to hook this up to say your Raspberry Pi it doesn't have analog input you could use I squared C instead. So this is the flow graph there's two versions of this sensor this is just one version this is the 7.5 meter per second max versus the 15 meter per second max and you can see the analog output is like you know linearish they do give you a table that you can use to calculate and then in the middle is the analog voltage 0 to 5 volts and then on the right is the output in counts so the I squared C which is not actually not linear but the I squared C output will give you a digital count and then you can convert that to velocity. The I squared C interface is pretty straightforward you know you query it on address 50 you get 5 bytes 3 of those bytes are checksum beginning checksum and checksum and then there's 2 bytes in the center that contain the 12 bits of measurement data so it's pretty straightforward. I whipped up some Arduino code in like 10 minutes and it worked just great you know I blew into it and you know I'll show the demo as well it increments the numbers and you can plot it very easily so this is me sort of blowing into the sensor while running the Arduino plotter and then I can also show that. Yeah so it's available at digikey there is some in stock there's 14 right now and let's do your demo and then we have a video. Yeah so let's show the demo so I just have this hooked up on the overhead here let me just turn on the autofocus lock so I've got it on a feather and I'm just using a static UT cable to make the wiring easy this is the sensor itself so you can see it here and then this is the slots you can see there's there's no impeller there's no mechanical connection but there is a hole that you expect air to go through and then you know the natural just like you know air flow from room is about 500 if I go over here and blow into it neat you can see you can see my lips there. You won. Yes I win the game which is you can make the flow rate sensor go up so works really great it's a very easy way to use it and I love that it comes with both analog and digital sensors. Alright here's a really cool video we'll see on the other side Let's get started. Okay and so that was a fun video and also you can see how to pronounce the name which is actually like why I picked the video and how do you present also I didn't know that they owned all those companies like I didn't know dialogue when it was the best part is you can imagine when they're putting us together they're like hey we need to show how we've globally expanded but we have the samurai but the samurai has to get on a plane and you're not allowed to have samurai swords on planes this is not the kill bill universe where samurai swords are allowed I just like that they it was that thoughtful they're like they got to get on the plane but they can bring a sword with them. No so like you just drop the sword off right there yeah yeah you can get all the way through security but on the plane do the right thing drop the sword maybe he also realized that the next journey for him did not require a sword maybe he doesn't need it anymore Blade cuts both ways so that's this week's IonMPI IonMPI in the chat you guys said sword drop is the samurai mic drop it's true it's just like I'm going on a plane okay let's make sure that y'all know what the code is Microbots and let's do some new products lady new new new new new new new sword drop new new new new new new new new new new new alright store your hopes and dreams in the overhead compartment lady is going to break down bam okay we've got actually this this week is all JP's favorite products JP's recommended a couple items for us so like house children JP really likes old synthesizers and these are step switches they're very evocative of the TR-808 and other synthesizers and drum machines they use these kinds of step switches we have them now in packs of 3 what's cool about them is they're hinged they've got a great tactile feel and of course they've got that 3 millimeter red LED built into them on the bottom so actually let's go through the colors we have red LED we have yellow with red LED and we have blue with red LED alright do you want me to just show the different colors well yeah but then at the last photo just stop which one this one so all of them on the bottom you can check this out from the data sheet that we have linked so the top two pads up there are the ones that say that there's like a negative and plus next to it that's the LED so the LEDs are red LED it's a standard 2 volt forward voltage 10 to 200 milliamp LED it does not come with a resistor so whatever you're pairing it with you'll want to have a resistor in line if you don't have constant current and then there's four pads four pins below and this is an SPDT switch which is a little confusing most momentary switches are SPST either they're open or closed this one the those pins at the middle are the single throw and then the two pins at the bottom are the sorry the single pole on the bottom of the double throw so one of those pins I think the one on the left is connected normally and the one on the right is not connected normally and they alternate so the middle pin switches between the two basically just means that like no matter what you're hooked up you know chances are you can use the switch you can also use it to switch between two signals if needed and then I have a little demo I can show so the LED and the switches are separated they're not connected together show them again and we'll have more colors we just got only half of them in so far so this demo is really simple I just have this hooked up to three volts and then I have the switch hooked up in series with the LED the LED and the switch again are totally separate but in this case I connected them together so that when I press this switch the LED lights it lights up nice and bright but it's a nice little indicator and of course you can PWM the LED you can have it be sequenced separately and it's very nice and clicky I'm going to bring it next to the microphone to get the clicky effect so imagine, hear that that's the click step switches we've got a lot of these and they're all different colors so I think what I'll do is I'll just go through the photos really fast because you all know what's going on here yep, these are Potentiometer knobs they're called the Micropotentiometer knobs they're sometimes, I'll say, well the demo we actually showed them on a rotary encoder it works with both and I'll show why but we have them in multiple colors cream, white, yellow, orange and red we'll have again more colors shortly we only got to taking photos of five of the colors we also have one special rainbow pack rainbow pack comes with ten colors red, orange, yellow, green, blue purple, brown, white, black cream so we're also going to work on trying to get clear translucent ones but they're actually made of slightly different materials so they're taking longer to get made for us so it's neat about these is if you look on the bottom actually this photo is really good just because it shows all the different forms so the bottom has this kind of like grippy thing going on there but don't worry about that because even though it looks like it's a T18 knob it's not it's actually a fully round 6mm shaft knob that will fit on any potentiometer or rotary encoder or what have you that uses a 6mm shaft which is again like 99% of potentiometers and rotary encoders and then there is a set screw and you scroll the set screw sorry you tighten the set screw after you've attached it to whatever you want and it will stay in place so you I do like that it's a little bit more expensive to have a set screw because it's a separate item but it means that we don't have to carry like D shaft versus T18 which is round works with everything and so yeah these are also sometimes called Davies 1900 style I think that's just some it's a good machine or guitar that used similar sized knobs they're not guaranteed to be that shape and color and size they're just in that style they're all the same to each other but they may not be the same as this style is the screw aligned with the indicator on the top that's your question the answer is let's go to the overhead for the answer bum bum bum bum bum bum and the answer is hold on this is the indicator and it looks like it's on the exact opposite side there you go this is on one end and this is on the other it's on the opposite side and they do go to 11 and we have the rainbow pack that's probably what you wanted yep and the rainbow pack and we'll have those other colors we'll have the green and blue and purple just we'll get them shot next week okay the starter show tonight besides you Lady Aida our community our customers and the entire Aidaford team is the MMC 5603 magnetometer it is such a tiny little it's a little chip in the center which was very exciting we haven't done a lot of point actually this is our first .4 millimeter BGA chip and we're basically using the sensor because as you may know there's a chip in the shortage the most popular magnetometer that we'd love to use the list 3 MDL has been tough to get a lot of ST sensors are and that just means that's an opportunity for growth that's an opportunity for us to go out and find more magnetometers and so we found the MMC 5603 we talked about on a desk of Lady Aida it's a wonderful magnetometer it's triple axis so you get X, Y and Z data it's three volt logic uses I squared C so we put a three volt regulator and level shifter yeah sorry you're pressing me yeah we have a stem QT connector on it so you can plug and play it for easy connection we recommend pairing this with gyro accelerometer so you can make a 9 doff sensor and then we have some header and it has a fixed address of X30 and it also has a range of plus or minus 30 gauss so it means it's good for measuring it's a 20 bit ADC 30 gauss the earth's magnetic field is about like one plus or minus one gauss so this will work quite well for measuring the earth's magnetic field it'll also work for some weak magnets but I will say like I put a rare earth magnet right up against it and it like totally was like whoa too much magnet so it's not great for really close up powerful magnets it is going to be fine for earth magnetic field if you want to use it in 9 doff sensor or some basic magnetic sensing and orientation so I've got a little demo you got some congrats from the chat on the BGA well you know what it's not me it's actually the machines team we did it I threw them at it and they succeeded okay so let's okay so this is a quick little demo just showing it's measuring the earth's magnetic field here because I don't bring a magnet with me but it works no this is fine it's you know just showing I mean most people are going to be using this for compasses and orientation sensing and so just showing it works you know very well for that you know the 20 bit ADC measurement means that even though it has a very wide range you get pretty good accuracy and precision I have a magnet in these headphones you might bring that over there I didn't test it, I don't like live demos are risky but yes this is a new megatomber where is the chip on the board can you point out where it is since it's so small it's so tiny I mean you can't see it here actually our photos are better someone was joking around that the chip shortage because the chip's got so small we just misplaced them all or something well you know ironically one of the things that's interesting that we've noticed is that you know part of the chip shortages we're finding that the chips that are available tend to be yeah there you go tiny the chips that are available tend to be I mean come on BGA yeah it's but you know it's 0.4 millimeter pitch you know and it's only four pads so it's not it's not too bad it's not too bad it's not too bad I think we use a 6.6 rule and yeah there it is in the middle you know we start with a breakout it's tiny but you know what good you know with the next version of the feather sense we'll use this chip it'll be nice and small but it does work very well I guess we have to get an electron microscope for our product for this oh the sensor also has a very very nice de-gousing de-magnetization capability which I do like it also has an onboard temperature sensor so all around it's a you know a very nice sensor but yeah it's about a millimeter by millimeter and that's new products okay load up your questions over in discord.it or discord.gg slash join all 35,000 of us we're gonna do some top secret while you're asking questions over there yeah okay top secret first up we're gonna play a little video of you making something and then we have three breakouts we're gonna talk about what are you working on here this is you know as I mentioned some parts you can't get and so we're always gonna look at for more part options this is from ST it's a very it's a NIST traceable I think 0.1 or 0.5 degrees Celsius temperature sensor that works over I squared C and it's always good to have more temperature sensors okay this is I think last week's INMPI we thought we'd turn this into a breakout board I toss on a crystal toss on some passives components and just see how this works it could be a good option for people who want to turn a high power thing into a low power thing and and this is the easy link that we're going to try bringing back from the dead all right that's a top secret I cast turn answer those let's bounce right there questions you've got them we answer them yes okay lady you were about to say something about some insights on the chip availability right before we I think I was just saying that the parts that are available are gonna be finer pitched so you have to kind of deal with that okay that you know if you're gonna discontinue something the company's probably gonna discontinue their massive SOIC or TQFP I think this is a question to figure out if we're replicants how would you ship a vinyl record to Florida during the middle of the summer without it turning into a taco ooh that is tough so I just got a record in the mail and it was shipped and they were it was shipped in a pretty stiff cardboard record thing but Florida I grew up there it was really hot if you were really that concerned I'd probably use dry ice and ship it the way you ship food because that's been kind of figured out like I've bought like food well air is a very good insulator so I would I would just put it in a very large box with like a very airy stuff in the middle that supports it but yet it's risky I agree yeah I mean if it was really valuable and really important I would I would ship it overnight and I would use you know a temperature control box that you can you know use dry ice with why did you turn the um vinyl record into a taco doesn't it sound like a blade runner test it's like how do you get to not be a taco in the summer heat what was the guy's name? the guy who's no the guy who's been questioned at the time oh good trivia question for the I remember you know what he looks like yeah good trivia question for the chat what was the name of the replicant what was the name of the replicant okay next up does a tiny sensor come on a standard tape and reel yeah it does very it's just like tiny okay but here's the thing it's like we I have to learn how to use these chips we have you know this is just what that's what's available and you know I think two weeks ago I think we were talking about a maxim class the amp it's only available in BGA okay question from twitch what is what is a good connector for .100 inch header pins that has a commercial grade hand crimper like the molex hand crimpers well to be honest I would just you know we have in the shop these um molex kits that you can like DIY your own cables and I would use that I would not hand crimp any connectors because I've done that and I hate it um but you know the .1 inch there's the Bergstick um there's molex um there's a couple companies that have .1 inch spacing but I really I would recommend just getting the kit that we have and just DIYing your own connectors what I like about the electronic community we have is the overlap of blade runner trivia enthusiasts and people who do electronics is very high and the answer is Leon oh that's right Leon why won't you answer the question Leon okay um are there any more BGA boards coming um um that's this is the only one for now but yes of course there will be more yeah um okay um are there uh oh wait uh when suggesting products to carry or new ideas do you consider PCB layouts to connect third-party products to a feather side PCB or a ton more looking for actual already made electronics in other words does it have a possibility to be considered or not really excited you just want to know for future ideas things um you know I don't I don't know until I see the idea um we have stuff that connects to other stuff but it's I do have to think about availability if it's like hey here's this really obscure thing it has to be really cool for me to spend the time and effort to design a board that said you should always send emails to contact us I think about 20 percent of the things that get sent to me get turned into products or stuff we stock yeah so you have like a one in five chance that's a better chance in getting into Harvard oh and the uh the person who asked the record question they ordered one of our records we actually have record um luckily for us um when we got these records we did testing and so these records are modern record not not that it matters but like these were made in the last you know 10 years and the pink plot the pink vinyl and the way that these are made apparently um they don't warp and bend yeah it's really thick it's like the 200 gram or 250 gram yeah and we've been shipping these for like seven years we've never had an issue with them we've never had a record not make it so um for really old records though that's where you have to be really careful um ages it gets us all um question I'm having trouble getting example Arduino code working for the OLED breakouts to compile for the rp2040 do you know if the Adafruit gfx for ssd 1306 libraries are currently incompatible with the rp2040 I know that they're not I know that they do work they're not incompatible which means they are compatible um however if you're using the Arduino embed core I do not guarantee that works because I don't own any boards that use it um so if it's if you're using like a nano 33 or nano rp2040 or something from Arduino that uses their embed core um please open an issue with Arduino and ask them to fix it because I'm using standard Arduino um and we use the Phil Howard core which is allowing third party boards um so it's I don't you know I'm using this core and I know that core works very well we use it like on a daily basis okay um next uh I have an air purifier is that fine for when I'm soldering or should I get something else for the solder for me so you get something else I think it's a good idea to have you know it's just something to pull the fumes away from you towards your air purifier if the air purifier isn't on your desk right if it's on your desk it's probably okay but if it's like on the other side of the room you want something to pull the can also make you know something that gets the solder fumes away but ideally you want to get them away and then air purifier somewhere around there yeah um and of course if you can it's not too hot open up a little bit of wind or two um are we only answer questions posted in discord on youtube as well uh discord and sometimes we get helpers to help us out because there's like eight different chats so we bring it to discord that's why we um age and magnetic media and music or the Achilles heal yep um so many masters tapes get lost forever it is true I know in like a fire it will take you out it is true alright and those thems are questions thems are questions thank you everybody alright thanks folks um just a reminder because micropots 10% off in the Adafruit store all the way up to 1159 p.m eastern time you can do it I want to say a special thanks to our Adafruit team let me see who's behind the scenes um jesse may jesse may in the Adafruit Slack chat running things behind the scenes helping our team and more um special thanks to everyone in the community all of our customers everyone who's um helping us keeping this thing going because every day is a new adventure and we will continue to ride this wave together this has been an Adafruit production here is your moan of zener goodnight everybody
