Live from New York, it's cinnamon toast crunch engineer now. It's live in New York. It's asking engineer I love it when I have chips inside my chips. Yeah, it's me lady a death free shrimps inside. I'm yum delicious All right, it's me lady a doubt It's a me mr. Lady a doubt broadcasting live from downtown Manhattan Where we have our a different headquarter do all of our designing manufacturing and apparently shrimp toasting We've got exciting show for you night one hour of the latest and greatest in maker hacker engineering news Gonna kick it right off because we I can just tell by looking at the display We got a lot of stuff to show stuff full of goodies not shrimp tails. Let's kick it off What's on tonight's show on tonight's show?  I can't wait to take a photo like these again very soon We hope Thanks for placing orders and please continue place your orders. It supports us one of the only if not only Woman-owned manufacturing companies in the USA and New York for sure So until people around the world showing and sharing their projects lady I'll talk about this epic show until there's like 15 people on there's a lot of projects We'll talk about that and more time travel look around the world makers hackers arts engineers current news and more Help wanted jobs at Adafruit comms where you can post your skills or if your company posts a job We have a couple that will highlight this week Python hardware news a couple things in the news and also some interesting trends. We're seeing more Python on hardware We'll talk about that I mean New York City factory footage factory footage from Adafruit. We do every single week You can see all things that we make the factory floor 3d printing we have a cool video from Noah Pedro of RP 2040 feather and then a really neat speed up from Dune, which everyone likes. It's a prerequisite for watching this show Did you key in Adafruit present by an MPI this week? We're gonna be looking at some parts from molex We have some new products. We get some top secret. We're gonna answer your questions. We do that on discord Adafruit.it slash discord where we have 28,000, but we're gonna be up to 30,000 soon I think I think we went from like 29 to 30 or I didn't get the latest graphic and Either way, I know we're coming up to 30 soon because Kani was talking to me about the art that we're gonna do for it all that and more on you guessed it ask an engineer All right, so let's first talk about What's happening? We are shipping safe and smart. So what does that mean? Yes, we follow all our protocols to keep our team safe We're still not through this yet. So Some of our team who's been eligible has gotten vaccinated. We're in New York. So right now it's 50 and up. There is teachers. There's Essential workers that are public-facing We are not in the category of essential workers even know we're essential workers Because we're manufacturing and also the construction Industry they're also like hey, but we're all gonna wait our turn we're all gonna continue to mask up and be as safe and smart as possible keep our team safe and All of our teams were masks and gloves and we do Daily temperature you name it we do it every single day and we also put in a free mask For any order over a dollar. Yep in the USA. We've been doing this for We're gonna do it for a hundred days. We're already past. I think the halfway mark. Yeah, so we only have it was April Sorry, it was a January 20th, so it's now 60 days in yeah a little bit over half halfway there And we also have other freebies that we do when you place an order. Yes I'll tell you all about them nine nine dollars or more. You get a free perma-proto Half-sized breadboard one for an item or more you get a free Stemic your keyboard. We have a range of about like 20 or 30 different boards You'll get one that's in stock from that range You'll get a different one each time if you make an account We'll make sure that you don't get the same one twice if you don't you're just gonna get random one one nine nine or more you get free UPS ground shipping and Two nine nine or more you get a free circuit playground express or all on development board that has sensors and buttons and LEDs all built into it It's a great way to learn programming and making without any extra tools required to plug in a USB cable You can be coding in make code or circuit Python or Arduino in under ten minutes Okay, next up show and tell people around the world showing and sharing their projects It was a gigantic show and tell we Are alternating hosts from Adafruit this week. It was Lee data night last week. It was no Pedro Next week coming up is gonna be JP. So Show your projects you can doesn't matter which one you show up at and then some folks are showing projects in different states of Dumbness I like that and that's also really cool too because then you can look back and see the project from the beginning So who was on the show until this week? We had some people we started off with Kevin who's working with his daughter on making an orary Which is like a thing that shows the planets and moon and sun and etc. Moving around each other using some servos and an RP 2040 feather So for that project will it'll be a good science fair project or science class project Erin firepixie came by with an LED snowboard that she's building So she's gonna go snowboarding and she's gonna be lit up and she's got a sensor That's in the on the feather that's driving the neopixels that knows which way she's turning So like maybe those sides of the LEDs will light up Melissa came by with an apple to see she's Restoring and also a CRT Like a really cute little CRT that that like pops on top of the apple to see And then Pedro I showed off their feather demo. They have all these Lego compatible brick add-ons for our various Stem of boards and feather boards you can make a little arrangements and put them to Lego They love Lego and Scott showed up his SPI flash collection He's got like one of every flash and he's gonna be using that to Create a database of all the different Q spy and spy Non-volatile memory chips so we can have like you know circuit Python and Arduino and all the other software use that Talks to SPI flash chips each one is a little bit different in slightly different ways And it's if you you need to know which one you're talking to to make sure that you set the right bits And all that good stuff is required for the RP 2040 It's also required for circuit Python. So it's it's part of the the way my controllers are these days your flashes external You need to know how to talk to it Liz is still working on our sailor moon star lock it she 3d printed a case It looks very cute. She traced out the anime cell to make the 3d printed model Alex made a ESP 8266 Programming adapter because it'll like ESPO one modules She made it into an earring so you can wear it at all times and it's got these like buttons and it looks Kind of like a Ouija board thing Very cool very goth after dark PCB design Psy made a Pico Raspberry Pi board to cellular and to adapter and Also added semi-qt so you can do cellular communications with an RP 2040 Ron Made a home sensor system with an ESP feather some sensors in the ink display 2 2 3 1 puppy made a carbot and that can is controlled by an Alexa And you tell her where you want to go and it drives a little mini car Joey is working on the pie quarter made an air quality app using the the pie quarter circuit Python power and sharp memory display like handheld device Ariel is working on a college car project and is in charge of the strain gauge Data acquisition system and got the strain gauge working. Congratulations. Those are like micro volts They're not easy to deal with but Ariel got them working Dan has been designing more and more PCBs a badge art project that looks like the perseverance bot an own parade Digital resistor like a resistor that can be Switched between multiple values using like good like our to our ladder Mark is still working on the neopixel numbers for his house so that delivery people can find his house in the dark and David Figured out a hack where you can plug in old I squared C sensors on to existing stem a QT boards to make little stem a QT Like stacks of boards. Good idea. All right, and that's shown so we do that every single Wednesday and some of 30 p.m. It's part of our eight different life series of shows you're watching this right now Ask an engineer a p.m. Yes, so I'll tell some of you just talk about that Those are our shows for Wednesdays that we do in addition to 3d hangouts with no on Pedro On Sundays, we do desk of Lady Aida On Sunday of this week Lady Aida. We showed a few things. Okay. I got our P20 40 stuffs happening So I actually got the QT pie going and working So that was good. I got the tester working as well I showed a we made you know some videos with the RP 2040 tester. We made We also got the watery trinky going. Maybe I'll bring it down. I'll show it on it's not out yet. Don't ask And what else did we show off? We showed off some more mechanical keyboard stuff. I am X chips Oh, I am X things that we're working on Yeah, basically starting to get some older projects up and running again. Yeah, and then we had the great search And on the great search where Lady Aida uses all of her engineering powers Teamed up a digickey to use the digickey site to search for Unique because there's millions probably if not billions billions and billions of parts my favorite thing about The great search is when I search for something I'll also tell you all the mistakes that I've made That you could try to avoid making those mistakes. So for example, you know, did you know that order encoders come with two different? Nob type ends and they're completely incompatible. I found out the hard way Why don't you learn from my mistakes? So you don't have to order stuff and then return it or? You know have to deal with them a mixed batch of potential on their knobs or rotary encoder knobs Yeah, the great search series you should just watch all of them if you ever do any type of parts purchasing you'll not only save time but save money and We show all the mistakes and more because that's the best way to learn is See sometimes other mistakes not just successes But you get to save time because it's like oh someone else did all that mistaken for me Yeah, so now I can do all the searching. Yeah, I mean, it's not a bad thing if you make a mistake But like if you can avoid it just save you time. Yeah Also, no one should feel bad if they can't figure it out because also you see I make mistakes, too Yeah, and so I think that's important that we show that all right, so on Tuesdays We do JP's product pick of the week where we broadcast live from the product page And this week was the VC nl 4040 proximity and luxe sensor and here is a recap It's the VC nl 4040. It's a proximity and luxe Sensor in STEM a Qt format if you look here at the display when I get my finger a little closer I've got my little smiley face winking there this little sensor does a pretty great job tracking Whether you've kind of added that little fleshy mass of my eyelid coming down. I'm gonna just use my blink control I'm gonna use that to trigger the synth My product pick of the week this week it is the VC nl 4040 it is a proximity and Light sensor and I'm gonna go ahead and place that on my STEM a Qt board of awesomeness Okay on Thursday there is JP's workshop and Here is a little recap of what was on last week's show and potentially preview Okay, so tune in tomorrow on JP's workshop and then also Scott is doing a deep dive tomorrow so tomorrow there's two shows I know lucky y'all get two shows double the show all right time travel I'm going to Start it off with some Terrible news terrible things that are going on so last week on wednesday We were just getting some of the information because of the shootings in atlanta and you know adafruit has Customers community friends and team members in every location where there's been a shooting so last week we Wanted to say you know our thoughts are with the folks in atlanta And there wasn't All the information or ways that people can help one thing that we try to avoid as a company Is just to put up a hashtag and say okay, you know, that's it. We try to find ways to be helpful So we talked to our team made sure our team the folks that we have in the atlantic area Atlanta area was okay Figured out was there Fundraisers that are for sure part of the families It's one of the things now that go fund me. This was one example These were definitely the family members sometimes when these things happen, you don't know You don't know how to help and so we have a blog post on atafruit and From there you can see the resources that our team put together and then some of the ones that our community sent us so You know that was last week this week sure enough so Colorado and we all have friends family co-workers Community members and unfortunately, you know, this is the news 10 were killed in Colorado The information is still coming out So we'll do a blog post or we'll get the word out into our community about ways you can help We have a team member that's in colorado. They're okay that we just had a meeting Yesterday like please let us know what's helpful on the ground for people elsewhere what they can do and you know the bigger conversation that always comes up is like well, this is two weeks in a row the guns were purchased in a pretty short period of time and You know guns were purchased in or out of state. So there's always debate about gun control But the only thing I think that we can do because that's From we're an electronics company for us. That's that's almost unsolvable Gun reform but one of the things that we can all do is if you know someone who's going through some tough times They're acting different. They seem like they might do something. That's where friends and family can actually do something You can say hey like Let's get you some help I don't know any other way to solve this right now with the tools that we have So, you know, there's I mean, it's it's weird because we've been countries been almost locked down for a year and So this is kind of starting to get more shootings. So, you know, I think finding Finding a way for people to be solution oriented on solving this because you know every single week now You see these names and we're all we all know someone somewhere And we're all just like hoping we don't see someone we know But those are all real people that those lives are devastated as families are devastated So, um Don't have a solution for now We're an electronics company But I can say the thing that we can do is if you if you see or know someone Who's going through something that's the first and best way probably to stop it That's all I can do for now. So hopefully every Wednesday We're not doing this but we'll get the information out the best we can using our platforms That's we're gonna always do and um, you know, the only thing we won't do is just like hashtag, you know, we're here Um, we want to make sure that we're useful with anything that we put out there Okay, so switching gears completely, um onto good news in the time travel world Arduino day official is march 27th tune in Yes, this weekend 11 a.m on saturday Eastern time 4 p.m. I guess csc CDT time and you can see the annual Arduino day event We'll be watching do a couple blog posts or whatever. We already have a blog post about this event and uh It's another year. They are 16 years old. Wow Yeah 16 all together from 2005. I remember 2005. It's a big year big year for electronics. Okay Eight a box. We are full but you can sign up when we run the first round of Eight a boxes. There's folks that move or their credit card They switched up or there's openings afterwards put your name on eight a box.com There's a little thing to get notified when we have eight a boxes ready to go and you can Purchase them. They'll be shipping out in april ish Just keep in mind. There is a worldwide chip shortage. You're gonna hear about this every day forever. Yeah until it's over So just be aware everything is starting to come back. But coming back is not exactly the way you think It's not just a switch that's flipped. It's a global supply chain.  This is this is tough This is like, you know, there's only one Company that makes a chip and then they don't have any chips for i'm now getting one year lead time For for parts. So any one year is tough. All right other bits of time travel Philby is doing an excellent series of videos. Just posted up this one. This is about protomatter and i'll let phil take it away Here is led matrix tiling working in the arduino protomatter library This is when you have multiple led matrices and you link them all together to work as as a single Big matrix. We've had this in circuit python for a while, but it's there in the arduino library as well And you can see on the back here this is being driven by a matrix portal And then we have four matrices zero one two and three All linked together and when you have this many pixels, you can't power it off usb anymore So i've got a big five volt 10 amp supply. So there's lots of power for for all those leds And this is the uh in the protomatter arduino library. There's an animated gif example I just had to change some arguments to tell it I've got these four four matrices here.  It would look amazing All right next up We have a new series of short videos And it's part of colin's lab. Colony's colin lab shorts And uh, sorry colin's lab notes. They're short, but they're the notes Colin's lab shorts sounds like something you wear in the lab when it's like really hot Yeah, they're they're they're short videos and these are colin's lab notes And I'm going to play these back to back. They're one minute each. There's one two three four of these Yeah And these are across all of our social media platforms including some of the newer ones like tiktok where there is Um a community of people who like to learn and the constraints actually make it a lot of fun Because you have a minute and you have to do as much as you can in that minute with within these constraints And it's a telling a story each time. So we're going to play these and we'll see on the other side Sotter wick is great at removing excess solder It's a little more delicate than a pump which makes it perfect for service mount components like these bridged ic pins Sotter flows onto heated surfaces So when the wick is heated and pressed against the board it will melt and then soak up the excess solder First make sure you unspool plenty of wick to work with it will get very hot So hold it with a pair of needle nose pliers and place it over the area of solder you want to remove Thoroughly heat the target area using your iron by gently pressing the side of the iron's tip into the wick for a few seconds Then remove the hot wick using your pliers after the braid cools cut off and dispose of the used section Like a desoldering pump adding more solder can help keep the area hot longer allowing it to flow easier Above all be patient and make sure you're heating thoroughly an led's lens will often match the color of the light it emits But that lens isn't what gives the led its color An led's color is determined by the chemical composition of its internal semiconductor Red and infrared leds often use aluminum gallium arsenide Yellow and green use gallium phosphide and blue can be created from indium gallium nitride Color is created by light traveling at different wavelengths And creating these wavelengths requires differing amounts of energy or voltage Typically red leds have a forward voltage of about 1.7 yellow 2.1 volts green 2.2 volts and blue and white leds operate at around 3.5 volts So even if you don't have access to an led's datasheet you can make an educated guess about its forward voltage Desoldering can be a bit of a challenge depending on the board and components you're working with But for through-hole parts like these mechanical key switches a desoldering pump makes things pretty easy First prime the pump so it's ready to go Then heat the target joint with a soldering iron briefly When you see the solder liquefy quickly remove the iron from the joint Place the pump tip over the joint ensuring it has a good seal and then press the button Keep in mind that all of this is one swift action So the pump can suck up the solder while it's still in a fluid state like so voila If the solder is not coming off try adding a bit more solder to the joint It may be counterintuitive, but this will help the solder retain heat and stay fluid a bit longer improving the pump's chance at success Let's install circuit python on this raspberry pi pico and blink its led First download circuit python for pico from circuit python.org Make sure pico is disconnected from usb then hold down the boot select button and plug in usb While continuing to hold the boot select button until the rpi rp2 drive appears on your computer Copy the uf2 file you downloaded onto that drive The drive will unmount and a new drive named circuit pi will appear your pico is now running circuit python Download and install the moo editor here open up moo It'll automatically start with a blank file in that blank file type the following code Save the code to the circuit pi drive as code.pi and overwrite any pre-existing code.pi file And with that we just made pico blink All right, and we release these around like four or five o'clock every single day. I'm a day through friday Yes, something to look forward to one minute. It's been a minute. It's calling every single week More than you need. All right Um a couple ones that I wanted to mention So the job board is picking up pretty fast because lots of people are hiring and lots of people are posting your skills So there's a makerspace steam instructor that's mac inspires makerspace. That's a new york at a pay job designing designed fork of adafruit's 16 by two rgb icerate c shield into a 20 by four mega shield So if this is something that you're good at it's contract where you can check it out Go for it. All right. It's up in source It's on on hardware news. Okay All right, so we're gonna Do this one a little different this week This week I wanted to I picked a story out of the newsletter and the video. Okay, there's a lot, but I think that's interesting. So Uh, this is a new board. They called it a sbc small bar computer. It's actually just a microcontroller board. Yes, and um, why don't you talk about why this is Interesting, I'm just gonna do one sentence about why it's interesting, but you you have more so here's here's why this board is interesting It's the next chapter on how electronic manufacturers Are the trend that we see are sending out dev boards and that is it comes with a scripting language And the scripting language happens to be python. Yeah, so tell us about this. What is this? Well, I think it's interesting because I buy a lot of the valve boards Like I have I have many valve boards and I I use them for ion and pi And there's one thing that's kind of universal about a valve board is they always, you know, they're always kind of expensive They're this big they're expensive and they require a giant tool chain. That's a mess Well, no, they actually don't even require a tool chain. Usually you're stuck with some window software Usually it's it's only one platform window software. Sometimes, you know, some are now doing multi-platform If you even have a mac or linux, usually you're out of luck And it's a kind of a little clunky and it feels a little bad for the companies because it feels like every A valve board they have to sort of start from the beginning and like design the whole like User interface just to like talk to this chip and what I thought was interesting But Trinamic is you know, we featured them and they make these really great stripper drivers Um They want people to try the stepper drivers. They are a stepper driver chip company not a windows gooey software company, right? Like what are they good at? Stepper drivers, what are they probably not so good at window software? And so if you wanted to have a way for developers to be able to quickly test out Your stepper drivers or your like industrial control drivers Using something like a pie board might be really useful because you can like give them scripts And you don't need an IDE and you don't need like a You know a web tool or like a gooey tool.  Yeah, like that's like that's number one like oh my gosh and then Using any text editor or id you edit the python file and the thing is that it's not that different than you know what We just we realized with beta box and with doing rl tracks is like There was a limit like we actually couldn't get people going with arduino Like it was just too limiting because there's like you have to sell arduino and some people are like I'm on a chromebook and i'm like Okay, or they're like I don't have admin x that can't install software. Okay, or like, you know, they're at a library, right? It's like so how can you Or you know, they're on a parent's computer the parents don't want them to they can't download software But they can edit a text file or they have an ide That they're already allowed to use. Right. So how do they how could they edit a script? So the things that make it easy for students, you know, this is it's funny because it's like the You know, I always tell the joke of like well, you know We make it really easy for like students and kids to use circuit python Which means it's also possible for phd's to use it right because it's actually like kind of the same user base in a sense the same stuff that a very Like a very advanced engineer And a beginner it's actually the same user experience. They want like I actually don't want to install a toolchain Like when I was like in that medium stage, I was like, yeah, I'm going to sell a toolchain and I'm going to explore this thing Now it actually like gives me the willies. All right. I don't want to Get msp430 like to take over my computer. I just want to like have a thing do a thing I just want to test it out to see how it works and get a feel for it because I don't want to Integrate it into my own product So I think I think micro python is a good use case for this This is actually like basically a respon of the pie board. They call it motion pie and even in the name They're like, hey python. So this is happening. It's an stm32 f405 So you work with circuit python 2 and it's basically just kind of like They took the pie board and they just sort of added all this other stuff to it to make it good for industrial animation And it's probably just running micro python like plain Because you know the pins are the same thing and then it's just got like the buttons and sd cards It's just it's split apart and designed just for automation. I think it's interesting It's interesting because this is actually the one use case. It's very good for I always thought like eval boards We're such a waste of resources for a company that does not they're not an eval board company They're a stepper driver company. They should not be making eval board software. They should be making stepper drivers There's more people that can do python code too than embedded Let's see, you know, there's like there's a there's a there's a bigger community audience and talent pool as well So anyways, this is interesting does this is like you'll look back at this in years and be like, oh, yeah I saw this on like and then it's like the softwares on github. It's a bit interesting to me because Trinamic, you know, they just got bought by maxon, but they're not a big company, right? This isn't ti So it's interesting to see like these small scale companies, you know, are they like like digi like trinamic They're going to start doing micro python and embedded python scripting languages And then seeing how because they're more more agile than the bigger companies. Will it trickle up until eventually you're going to see um, you know big companies Use python on hardware as a way of doing rapid development for their chips All right, um other things in newsletter because that is in there is uh, we six point Two for beta for beta. Please try it out. Good. Ada for your we are sorry good is circuit python.org slash download fixing bugs like Yeah, like bananas. We love fixing bugs rp20 40 fixes are the big ones ESP 32 s 2 pieces as well A lot of usb stuff. Uh, keep putting in any bug reports We we are patching and preparing and we're going to move on to seven. Yeah, if you um, got a uh Circuit python a open hardware summit. Um goody bag last year they shipped last week or so and you can Run circuit python now. Here's the interesting thing. It's been a year and There's been a lot of circuit python updates since then so you get the latest firmware and your device does even more So this is a little circuit python powered badge that also function as a watch. Um, I think scott had these on Um, his deep dive. He did an unboxing here. You can see the front and back Um, there's updates the latest circuit, but I mean, I think a four without then now it's up to six Cool. And also, uh, there's a unboxing. Alex was on our show and tell you can also check out the Open hardware summit swag back unboxing that has everything else deep dive It's got this thursday we mentioned that before news from around the web Um, this was a round table from digikey for pi day. You can see a bunch of folks including jp This is a, uh, content full blog e-ink display with circuit python and iot This is a circuit So I tried to make her pi pico and circuit python to measure soil moisture. Uh, this is a raspberry pi mouse regular um Sensor sound sensor staff We have other pico projects Um Thermal printers displays Um More people doing circuit python with with rp2040s, which is cool. Yep Pi ladies, uh, has some good stories on their blogs. That's the pi quarter. We had that on the show and tell um This is cool. So chrome, uh, wephel. So more people are doing web serial. Thankfully web web usb long livid But web serial was better People playing with picos and an off-the-shelf hardware space This is cool. There's like like a plant shaped or like an egg shaped Sensor people love eggs and sensors. It kind of go together. Yeah, and if you want to check out, uh, tim He's doing streaming you could check out the bitmap tools and the neat little dial widget Gadget thing that he's working on And then check out the rest. Uh, we have a uh review that, um I think this russian site did of the 80 fruit feather rp2040. Cool. Tom's hardware also did a review of it It was a nice pi bass, isn't it? Yep. Here is a very small version of a schedule library for circuit python Um, you can use the pi pico to make an affordable stream deck. This is a 3d printed one Here's an esp 32 ola display with micro python and more and more and more and more Keybows with circuit python. Keybows with circuit python. Zubo's with circuit python Um, we have a guide on how to do Wi-Fi with the pico and then tom's hardware also Has an article guide on how to do it. So uses circuit python. He uses wi-fi Uses the read fruit airlift and you can then get your Pi online. Um, I had sent this to the team audacity 3o is released. Oh, yay. It's our favorite open source Yeah, so we use this for all of the audio file Edits and more Um, one of the cool things about circuit python and python on hardware is you can play Way files. Yeah, you can also play other types of files But you also you'll often want to put them in the right format speed things up. Yeah, there's that We talked about that. We have some coming soon. Um, we're going to be talking about it on show tonight We have some new learn guides and we are up to 306 circuit python libraries. That's right Check out the new boards and which ones are most popular on circuit python.org slash downloads And then we have some events coming up Picon USA is coming up euro python pie. Ohio and then of course virtual and then maybe throughout the summer We'll see some in-person events. Yep popping up and that is python on hardware news this week Thank you blinker Okay, next up. Okay. We're an open source hardware company We have 2440 guides. Lady. It was on the big board this week. Okay. Actually the top four guys are the Only new guys we've got this week. So we've got the Interfruit midi feather wings So this is a we've actually it's an older product that we forgot to make the guide live But now it is so you can add a din 5 or 3.5 millimeter midi jacks to your feather It's just over the u-art. Um, it does love does the level shifting up to and isolating for you Touchdeck school projects, uh, tim c foamy guy worked with jpe to make a diy customizable Like a stream deck clone, but it uses a rp20 40 feather plunked into the back of the 3.5 inch feather wing It's the rp20 40 is nice and fast and the 3.5 inch display isn't nice and big So it makes for a great project. We've also got the guide for our blm badge education and workshop kit for folks who Will be Will be getting these are going to be donating these to some groups are going to be doing workshops You can follow this guide to get your workshop up and running It runs circuit python and we're also going to add make code support soon working with make code folks um, finally, we've got a um a fun, uh guide from Dylan, uh, we did a You know almost a year ago now we did a uh coronavirus Uh stats update are using the ink, uh mag tag.  We don't have to uh, collate the data It's going to be collated for you by your government. Yay America Um, but instead now we have a vaccine tracker So, uh, would you like to know the percentage of people in America that are vaccinated every day? Your mag tag will wake up update it and go back to sleep. You can also customize it for just your state or your country all right, um in Adafruit learning system news if you go to learn data fruit dot com the top you'll see Our little logo with a mask on it. We're going to keep it on there just for now. Um, explore and learn new guides and then dice What are there's dice? So the dice are um A way to get a random guide. So I'm going to go to the Learn system here. Okay, and um, when you press it when you press this it goes to random guide random guide Oh Turkey Anyways, so this is uh a way for Once you have 2000 something guides, um, you may just want to hit the random button and decide What you want to make you inspired or maybe something that you Didn't even know you wanted to make Or who knows typical projects Things that you may not have known that we have yeah in the learning system. So stuff you can learn that is news About the learning system. We're always adding new features always making it easier to use Always making it better for more people to be able to learn it's a free resource And it's supported by your orders. So please play some water once in a while. Okay, main york city factory footage Here's some footage from the factory this is Making a tester making a tester a lot of our factory footage that we do Is testers because we do a test we test everything. So just test is how that gets made and then Uh, we like to make them use a you know arduino uno shaped pcb and um, what's nice about that is uh Then you know, we can quickly make new testers and this is uh isaac speed rounding rp 2040 testing so it only takes us two seconds to test it once That's why he's going so fast. Yeah, we have a video that we're going to show in a bit About that as well This is our special tester, which uses the mass storage capabilities Of a teensy to actually use like it shows up as a disk drive. It drags the file onto the disk drive and then Well, this is us testing uh this week's new product the neokey And the next week's new product the neokey 2 you can see how the other sensor works This is the Holding pins in a specific spot. So when it presses down, yeah, things stay nice and flat and here it is getting ready Squish and squish and like a pro Nice bead Nice squish. Okay. Got a back squish Yeah, squish both directions and for the folks for the person who asked, um They want to see a video of how we make testers. We actually talk about this a lot.  We have a guide Yeah, we even have a guide So check it out. We also talk about this at desk lady aida And I think we also did with the digi key video series make it a market All right, and it would be made in york city factory footage without The disney building across the street that's still going. So here's a time lapse of all the construction Going on across the street. They're starting to fill in Usually they took away the ramp I wonder how they I guess I guess they have to just build every floor now. I mean, maybe they lift the Maybe they lift it out within the crane. I don't know how they bury them. You think so? Yeah. Oh, that's cool All right, 3d printing known Pedro 3d printing up Some amazing things this week. We're going to show two videos Uh, one is a 3d printing thing is speed up and the other one is an rp 2040 feather video Take away known Pedro. I'll play these back to back and see you on the other side This is the feather rp 2040 featuring the new chip from raspberry pi This has all of the goodies you know and love about the feather format It's got a megabytes of flash usb-c built-in lipo charging and stemma qt With onboard stemma you can plug and play all sorts of i-squared c sensors So you don't need any headers. You can simply just plug in some cables This makes projects easier and there's tons of stemma qt breakouts for made of fruit With circuit python you can quickly get your projects up and running to install circuit python Plug in a good usb cable into your computer Hold down the boot select button and then plug in usb Head over to circuit python.org and search for the feather rp 2040 Select your preferred language and click the download button Then just drag and drop the uf2 file onto the usb drive The board will flash the new firmware and automatically reboot the drive Be sure to check out the learn guide for demo code and project examples All right, don't forget every once a 3d hangouts you can learn how to make all this stuff more familiar on Pedro Everyone's favorite segment digikey and a fruit present This week's iron mpi is from molex molex, okay Well, we're doing another molex when we did molex custom cables a bit ago That's right But I saw these pop up on digikey.com slash new and I was like that's a good idea. These are the molex one touch FPC connectors So these are connectors for flex cables. We have flex cables in a lot of use cases. I'll show you a couple in a bit And these are the two connectors. They've got ones that are Right angle and they've got ones that are vertical and you notice it has a little push bar It looks like like the you know an exit push bar from like a from a door And that does exactly what you think it's a way for you to connect and disconnect the flex cable from the connector by pressing down to lease it so flex cables You know we see and they're they're using a lot of things they're used in you know Almost all electronics these days. They're inexpensive It's an easy way to have multiple contacts on a pcb You know, you don't have to do a lot of crimping if any And you basically can fit a lot of connectors into a flex cable because you can use 0.5 millimeter millimeter pitch Which is not too hard to solder and your pcb's your flex pcb's are the precision Is going to be good enough that you can cram that many connectors in there's also 0.3 millimeter although we we tend to use 0.5 These connectors are also 0.5. So, you know, for example, here's a tft and there's a flex cable So that means it you know, they can bend quite easily and on the end you see one through 50 50 connector points on the fpc And then you would plug it into an fpc connector. So this is like a molex connector that we have that's a kind of like a Pull push like an ears style. I call them connector slide out or you know, whatever the technical name is for these and Basically, you see the contacts on the end because you can't solder a flex pcb directly to a circuit board Without causing strain and and having it rip apart what you do is you slide it into the connector of the connector Actually get soldered to the pcb So this is what the connector looks like when not in use.  So let's go to the overhead and I'll show What that looks like in person. So here I've got like a nice cool square tft display And this is a little breakout board that I've got that has that same FPC connector Like I said, it's a slide out style and you see there's these little ears I pull on them and then I can remove the fpc You can see the fpc contacts here and then there's top contact and bottom contact and then again if I want to Insert it It's the wrong contact way. I'm just showing it for demonstration And then you have to squeeze this ear and you have to squeeze that ear So, you know, there's pretty much work and we use them a lot Um, but there are some things you have to watch out for with these connectors, which is that They're extremely hard to rework and they Are a mechanical part that if you have people doing repair Or maintenance on something with a flex connector, they can break and when they break it's kind of like catastrophic Um, so, you know, you can see here on um the left I don't know if you can zoom in onto the connector, but uh You know, basically If that little piece that moves, um Gets cracked or broken and um from heat it can get cracked or broken.  So you see like on the corner there it got cracked a little bit Either from heat or from mechanical strain and you basically have to replace the whole connector And there's a lot of like little plastic bits that can break on these fpcs And then really hard to rework here's here's another one and you can see the whole thing just broke off, right? So that the you know, maybe it was you know, somebody flipped it up and it was stuck a little bit They didn't pull while flipping whatever either way Um, it cracked off and broke and so it's really neat about um these The molex one touches is um, you know, they come in different sizes and again, there's no like mechanical Pull or flip part you push to release the part Um, and so there's like one less thing that can go wrong The reason I mentioned this is that you know, if you have a design that has these flex connectors and you're either assembling them in automated fashion or you have people and You know, they break one out of a hundred of them Um, you you have to rework a board which can be like quite a bit of work and might damage other components on the board Because it's a big part you have to heat and remove Um, and also takes time and it might be better if you just you know upgrade to one of these one touch connectors Because you don't have that Mechanical strain problem. You don't have this part that can break off. Um, you just push to Remove the cable and it also locks in place. So maybe let me grab One I have yeah, there's one digikey the number that I use to find because there's a few different ones Is 245 50 440 that's the molex or you can go to digikey.com 4 slash short 4 slash r and 8 r w 87 Three so I found my campus. Let's go to the overhead again. So this time I'm going to again Yeah, you have to like carefully open up both ears and you never know like sometimes I actually break You know, you can break these You have to be very careful with them Okay, so this side And then this side Okay, and then you can remove So this is the uh one touch connector. So let's You can zoom in a little bit um, and so you can see uh The push this is the push button here. Sorry. Yeah, this is the push button here It's kind of hard to see the uh, there you go the engraving on it Um, you've got the context and you've got the mechanical strain relief here to keep it in place And then um to plug it in What's interesting is that you don't push to um attach you actually just press In and it actually has kind of like a wide curved mouth thing So you don't have to like be careful like, you know, it'll it'll slide it and it'll align properly Um, and then, you know, it's nicely solid and then if you want to release you press So you saw I was pressing it and I guess you could also press if you want to insert but you don't have to So there you go So it's inserted press To release there you go. So so and they're good for 20 cycles Um, this is the vertical type, which I thought was kind of neat, but they also have the right angle type So let's let's chance of you or the person doing the maintenance cracking off That piece so I think for that purpose alone And if you have a product that has this issue doing maintenance or rework or installation, you know, right? Because this is like part of your You know rework or yield issues Check out these connectors. So they have them in You know 10 20 30 35 40 Maybe I think 50 pin maybe not 50 up to 40 pin connectors vertical horizontal And they use like pretty much the same footprint as existing molex Um, fpcs, I mean check the datasheet, you know to make sure that you've got the exact right position for it the mechanical pads But chances are if you have a design that already uses fpc connectors You could probably swap these in without doing a huge board revision Right, you might have to just tweak a couple pads, but you're probably not not going to have to move around a lot of parts So very interesting connector. I think it's an interesting innovation Um, because I've used pull out and flip top. I've never seen push to remove or push to insert type and we have a video That's right. We'll expand a nice video The easy on one touch ffc fpc connectors by molex These connectors feature single step mating With an auto locknail mechanism A high retention force and an easy to use push button for unmating Offering a quick and reliable connection as well as easy operation makes the easy on one touch ffc Fpc connectors ideal for a host of industries and applications from smart appliances to various consumer and industrial uses The easy on 0.5 millimeter pitch one touch connector enables quick and easy ffc fpc cable insertion And mating operation via manual or automatic assembly The large lead-in helps avoid misalignment While the inside locking mechanism ensures superior retention push button to easily unlock the cable Other features include its high operating temperature optional ground terminal and right angle and vertical variations More information at molex.com All right, that was on lmki. Okay, let's dive right into new products. That's right So we have a coming soon. Yes. Well, it's coming soon really Uh, so this is something that we worked on like a year ago and uh, we kind of got delayed and distracted You can you can tell when we took this photo because bitcoin was uh, 10 10,000 usk But we actually are back on the imx train We took a little bit of a detour to do some other things including keeping our company running During 2020, but we're finally able to get back to some delayed projects including this one So it's our first cortex m7 board. It's going to be the imx rt 10 11 Which is a 500 megahertz cortex m7 from nxp It's got 128 k of ram. It's going to have a four megabyte q-spy flash chip We have circuit python already working for this chip and we're starting to you know going through a bug fixing stage We're also i'm gonna give it a second stage bootloader So we've been working on getting t u f2 all ported over and working quite well for the imx series This will be the first board of a mini imx series Chip breakouts and feathers and metros and pipe portals and whatnot Um, we thought this trip was cool because it's like it's a hand solderable 500 megahertz processor It's just kind of neat And it is very fast with circuit python. It doesn't have a ton of ram But it does have enough to be able to do Wi-Fi projects and and control the display and and get sensor data. So we'll be our fastest megahertz Metro so far. Yep very exciting next up. Okay. We've got some more We're three pi compute modules This one. I mean every day. We're kind of getting more modules in let me verify The two stats for these so these are Yeah, because one has flash this one does not have flash memory. So the one without flash memory is the uh Two gigabytes of ram, but it does have wi-fi and bluetooth. So this is the light version So you'll need an external sd card Um with the compute module But if you do that, uh, you've got two gigabytes of ram You've got wi-fi and bluetooth on board and this one you can see the flash chip Kind of in the top center there. It's got eight gigabytes of mmc flash memory two gigabytes of ram and of course wi-fi and bluetooth So this is you know, if you grab our compute module ioboard plug this in And again, if you don't have the mmc memory, you're gonna have to plug in an sd card If you have the mmc, what's nice is it it's got this super hat fast High-speed large memory chip right on board. Um, so a lot of people prefer that to having an sd card Okay, next up we have a lot of cables. We have a lot of cables. Uh, it's a cable series. These are 1.25 millimeter pitch Cables they're compatible with molex picoblade. They're sometimes called like picoblades, but they're not necessarily Molex they are just 1.25 millimeter pitch cables Um, they are one two n and I can show on the overhead what that means Because there's two there's two kinds of cables So let's uh, let's go to the overhead and I'll show so all the cables are pretty much This you know, they're just different number of pins So let me just make sure that we uh lock onto the focus So, um, you'll see that they have, uh, you know the contacts they're crimped in and all that good stuff Um, so for this cable Oh, sorry this one this one is one to one. Um, made a mistake. Um, so you can see that um The the colors may not be the exact same one as your cable, um, but for this one it is Yeah, this one pin one is uh, the black wire and this one is pin one is also the black wire So just make sure that when you have your boards that are connecting back and forth sometimes like The black wire on one is on one here and is on like, you know, the nth pin over here So just like keep and keep that in mind when you're designing it. Um, we've seen Some cables are they're called one to one and some are one to n So this one, you know, it's it's the same on both sides But that's not always true I just want to warn people because we might also carry the cables and have it the other way around That said we have them in multiple different pins. We have seven pin eight pin nine pin ten pin basically four through ten um They're pre-assembled cables. They're really nice. Uh, they're 20 centimeters long. So, uh, if you're Just you want to connect data and power from one board to the other You don't want to use a flex cable. You want a fine pitch or a fairly fine pitch cable We do like pico blades. We use them a lot. They're very compact. You get a lot of pins Without a big connector. So they're not very bulky. All right next up Next up we have stemmyqtfi'd the htu 21d breakout. This is a humidity and temperature sensor from te. We like it. It's an eye sensor It's got a ptfe filter also quite nice We've had this one for quite a bit and it's a popular sensor So we decided we would stemmyqtfi it now comes with a plug and play stemmyqt connectors on the side We're trying to get all of our boards into the same form factor same pin order Same connector to make it easier for people to um do no soldering sensor connectivity So the htu 21d had gotten the qt glow up as we like to say. All right next up Okay, now we're on to new products from fabrication department. So um, we've got This board. Let me grab the demo So these are um mechanical key breakouts So i'm kind of getting interested in mechanical key parts And to use them, you know the mechanical keys themselves.  This is a a kale box switch, which is cherry mx compatible You plug it in to um the breakout board and there's on the bottom You can see on this photo. There's a socket and so the switch doesn't get soldered in it actually kind of Press fit plugs in It can be removed. So if you want to be more permanent, you know use glue or something or or some Epoxy to keep it in place There was also on the bottom You see that white square thing that's a neopixel and there's also a diode and the diode is what lets you create Key matrices with this thing and the neopixel You see here there's this kind of like You know, there's the two sockets on the left the center is the the mounting post on the right There's actually a little slot in the keys and the key Itself is meant for like having an led soldered in perhaps But you can also just have a reverse amount neopixel shine through And then you can kind of backlit the led with rgb colors One thing to just be aware of it's not in the center, you know, it's the bottom half of the key or the top half It's one half the key that gets rgb lit Here i've got some translucent keys so you can sort of see that it's not the full body of the key It's not like, you know whole thing glowing. It's just one half of it So let's go to the overhead and i'll show you the demo because it's actually easier to show So you've got a stem at qt. Sorry a qt pie board You know, it's just using arduino or you can use circuit python or whatever And these are the keys and i'm just going to remove them to show you that um The key itself plugs into the sockets. This is the key and it's got these two Connectors and that those when this key is pressed those connect together And then there's the mounting post where to keep it mechanically stable so you can Plug it in and then, you know, it's pretty stable I would say look you want to have a glued or taped or something to to keep it from coming apart because you can Pull it off And here's another one. So you have two of them connected together And then on each side you have multiple pinouts There's power and ground here for these are for the neopixel and then this white wire you see You know goes in here and then chains over to this one. That's the neopixel data line So just like neopixels you chain them together. This Has neopixel data going through and then You have two pins for the switch the top and the bottom that and in the cathode of the switch Again, there's a this diode in the middle so you can make key matrices If you're not doing key matrices, you can just ignore that diode there to avoid key ghosting if you're making a complicated matrix But basically you have one pin for every switch and then for this demo I will reassemble it very quickly When you press the key the led turns off So, you know, you can just use it as a switch and then control the neopixel separately So there, you know, the neopixel is not connected to the switch at all They're totally separate. You can have the neopixel all the time off all the time You don't even have to power if you don't want to it's just kind of a bonus extra It shines underneath. Here's a demo of the opposite when you press the button the neopixel shines through So it's basically a breadboard friendly way of connecting a mechanical key that is cherry mx compatible to your breadboard It'll do more stuff with these keys But I wanted to just can get started And have an easy way to make breadboard friendly mechanical key switch projects Okay, and star of the show tonight besides deleted our customers or community and our team is Neo Trinkie Neo Trinkie your best friend who's neopixels? And it's a trinket and it's the usb key It's neotrinkie Uh, I don't know it's from bandai. No, it's not it's from made of fruit. It's a usb key And uh, as you as you might expect it's it's got the usb connectors here. So you plug into usb It's got a samd 21 is our favorite little microcontroller chip so it can run circuit python In fact this demo circuit python It's got a regulator just to get you that three volts you need Doesn't need a lot of components. There's a reset button And then there's four neopixels and two capacitive touch pads. So You know these contacts here at the end of the Body if we zoom in you can see that there's there's a split in the middle left and right. So When I plug this into usb signal usb extender When I press one it gets bright and when I press the other Wait, hold on Sorry, this one gets dim And this one gets bright so I can dim Dim them Brighten them so they act as two separate inputs The capacitive inputs you can control the neopixels separately You know, so I just have them doing this kind of a rainbow glow thing And then of course you can get into a boot loader or you can load arduino code You can use circuit python. It's very small and simple. We just wanted to make like A keychain circuit python board It has a little slot here that you can put onto a key chain ring if you'd like And then you just plug it in and you can immediately start coding and again You don't need an ide or anything. You can just go straight into circuit python And write code for it. So it's very cute and it's got an extra thick pcb So it plugs into usb quite nicely. Um, so trinky neotrinky. We're not That's new products Neo trinky, neo neo neo trinky Okay, let's um, I have some questions lined up. We'll um, we'll get to those in a bit And uh, folks will probably have some new questions. Let's do some top secret. Okay Get into the vault.  Yeah, I have a I have one little video and then we have some still images Some of these we just released the products and not exactly top secret But kind of it was working progress at the time. So here is behind the scenes. Here is us, um Testing our feather 2040s with the teensy. Okay. Lamar. What is this? This is my rp 2040 tester for the rp 2040 feather We finished this up and I want to show how the testing procedure works I use a teensy and the usb host and this is really cool I actually load the uf2 over mass storage Onto here. This is my test jig. So I test all the pin connections. We just milled this on our other mill If I crank it down here and then Press this button It loads the uf2 file does a serial test and the finish is testing two and a half seconds. It's awesome Um over here. We've got the eagle cad file for the testing jig You can see I test alternate pins that are not uh next to each other And then this is the uh pico sdk code that I load onto the feather to do the gpio test This isn't raw c. So it's really really fast. So two and a half seconds is awesome. Yes Go test um one weird thing so I put this up on youtube as well and uh because I guess Gmail does this feature and then also youtube does this now when you're logged in and it's your account for youtube It looks at the comments and it has suggestions on how to what to automatically reply with And some folks that said Hey, I want to see the code and all of the things already filled if I click one button It says look in the description look in the description look in the description Yeah, because I guess it analyzes and then so it had No I don't know Look in the description So anyways if you want to cut for that it's in the description of the youtube video or you can look on the blog post for that. Okay other things we have Cutie pie that we were oh the cutie pie rp2040. So I was I actually finished these up and uh Just doing some testing and making sure everything was working Um, but these are ordered very exciting tca 4307 this is an older breakout. We're going to finish that up real soon And uh, it's a it's a cool. I squared t Bus buffer It's a dvi breakout. It's not hdmi. It's dvi I was going to use this with the rp2040 stuff to get um dvi video out to uh displays that have dvi in And uh, sadly the stmpe 811 is no longer being manufactured But we're looking at other spi or i squared c we just have touch controllers check out our Great search for a couple weeks ago. I think this is the t sc 24 of 7. I don't know. I don't know the number And then um more experiments in neopixel keys So what if we took four of those like neokies put them side by side and then we have like a seesaw To connect them to i squared c so we can make like i squared c plug-and-play stuff. I don't know cool and then rotary trinky Uh next door neighbor to neotrinky. They're best friends. They used to play together as kids Um, and now rotary trinky is uh coming to life Get back to secret. That's in the ball. Okay, so Uh, we will do questions. So Put them up on discord I'll uh put every little bit of reminder where we're at discord.at for dot at slash discord Yeah, we get to those are the easiest ones for us to find and see and I have some lined up. Let's uh, Let's go. You ready? Sure. You can speed around. Yeah, yeah It's okay. Okay. Uh, I was soldering. I don't have a nice fan. I opened a window used a mass Is that smart use mass for soldering limiting what you inhale?  Yeah, I mean like it's it's basically whether you know, you You have a lot of flux or fumes. Um, uh, there's you know, the fume suckers and with the filters Opening a window. Um, you can wear a mask if people have masks Why not wear it because that'll filter out the fumes as well. Yeah the the With the particle the p2 or like whatever that particle is I found that that works pretty well For um, any type of air yeah particular. I mean they get it'll it'll all filter it out So yeah, you can yeah, you've got extra masks. Use them all soldering and if you can open a window always do that Okay, is there a shield or something an example to control a water motor of a half half horsepower Motor, it's a big water motor for recirculating water for a small pool. It's part of aquaponics Small lab. I want to build for longer. I would use like a relay at that point Yeah, it's a relay the relay switch. Yeah, because you're just turning it on or off It doesn't have to go to the director. You don't want a motor controller. You should really it's not a power switch tail because those are Uh, the back in the day. It's uh, what are they you can use a power switch tail if you want I mean if it plugs it if this half horsepower is power Whatever we have now it's like the equivalent, but you want to relay.  Yeah thing Okay, uh, I'm using a feather mzero laurel on an stm nuclear board There are two gpo connections between the boards and a serial signal the nuclear board powers the feather from its five volt input But I have found that if I plug in a usb cable to the feather To program and forget that I have nuclear power the feather tries to power the nuclear via gpo Yeah, this burns out the gpo and the feather any suggest a way to prevent this one person said data only cable and then some Resistors in series. Um, yeah, I was just using series. I just put like a 10k in between that way You're not uh, I don't think you're necessarily going to burn out a pin But yeah, you're going to definitely be backpowering and it's not going to be happy. Okay Um, the toggle switch capacitive touch center breakout It appears you brought the connection for the touchpad to the surface. Is that okay expanding to the re-switch? or other light components Would it still toggle? Well, I don't know what a capacitive touch would do with a re-switch a re-switch is totally different. I mean, I guess If you had a re-switch you should use a re-switch It's a switch on its own. It's doesn't that has a connectivity Thing rather than this which has a signal output. So I don't I don't actually know what you're asking to do. So maybe post the forums Next up Can I use an iti biti m4? nrf 52 on a feather tinsi 3 point x adapter will ice grid c and spi be where I expect no, they're totally different that feather tinsi adapters for the tinsi Okay, I can get the next one How much of the tariffs hikes for components from china affected your business any impact at all? So The tariffs are From the us on imported goods Not from china. It's from Well, the parts come from china. Yeah the parts come from china on import the us charges. Yes, so it's the I always want to be clear It's not like we're paying money and then it goes to china. We pay money goes to the us Yeah, I don't think they're asking that. I know. Yeah, I know look a lot of people don't even know what tariffs are Hey, you know every opportunity to just Start from a keep on an agreed base of things. So does it affect us? Yeah It makes the prices a little bit higher. So we try to buy more so we can get better volume There were some refunds possible So we applied for some of those but basically everything's more expensive And we're trying to keep prices as low as possible for everyone. We're still very competitive But absolutely it made prices go up for us. Yeah, so it means lower margins for some things It also means some parts got more expensive for us And then for some things and i'm sure this is going to come up soon We might just have to like not make certain things if it's too expensive. Yeah, so It did affect things. Okay next up Um Neo-key plus rotary encoder. I guess that's a sure. Okay. Any recommendations for sourcing bulk sk 6812 minis I think did you keep probably Stocks neopixels by the wheel. Okay, check them. I'm just curious to consider stock inexpensive ask pt 2260 430 30 megahertz boards popular emphasis like ebay. Just thought it might be a product to stock and replay them off a esp 82 66 3s p32 for controlling things in the home. Um Yeah, 43 is actually technically not I think supposed to be in the us We have 900 megahertz ones or 315. I don't remember which one But we do have a little pt 2260 controllers in the store. They're called just like rf simple rf controllers Is it i2c or i2c or just preference doesn't matter. I don't think it matters.
