 Life from New York it's Ask an Engineer. Hey everybody and welcome to Ask Engineer. It's me Lady Aida with me Mr. Lady Aida and we're broadcasting live from the Aida Food Factory in downtown Manhattan behind us. The factory is sleeping right now. It's not full of people. It was earlier today but everyone went home and it's just us left here like little mice screwing around feet going tippy-tappy and we've got an exciting show for you tonight but it's where we do all of our manufacturing and shipping and coding and hacking and videoing and music and all that all this creative and crafty stuff that we're always up to but the next hour we're gonna be checking in all the latest news and nudes from around the world. We'll explain what it's up with that with Mr. Lady Aida telling us what's on tonight's show. On tonight's show the code is nude start for noodles. Moodles. And we'll talk about that in a bit. It's one of our new product lines and Top Secret will even talk about how I arrived to this name and more but nudes 10% off in the Aida Fruit Store all the way up to 11.59 p.m. tonight. Talk about some Aida Fruit live shows including show and tell. Got some time travel. No chip shortage this week but we're gonna do some real world everyone likes that. From the mailbag we're gonna read your emails letters tweets and more to us we got some New York City factory footage. We've got some projects from Nome Pedro from 3D Printing Land. Ion MP Ion MPI. Kemet brought to you by Digikey this week. New products. Top Secret. Got a really neat thing that we're doing with the Raspberry Pi Pico W that y'all will like. We're gonna answer your questions. We do that over on Discord. AidaFruit.it or discord.gg. Join all 35,000 of super nice people. All that and more on tonight's show. Ask an engineer. Okay so like I said when we get to the I didn't know which section to put it in but we'll talk about like some of the product thing that we're doing including you know some of the restaurants around here. Yeah this is a place that we sometimes have snacks. Yeah and nudes. So anyways that's the discount code. We also swapped up our free stuff this week. For folks who keep an eye on things it's the blue fruit. Yes you can see it's slightly more blue so we still have the $99 or more and get a free half size breadboard. Perma Proto a great way to take your project in making permanent. $149 or more. We get our KB2040, RP2040 powered goodness with Stem IQT and buttons and lots of memory and USB-C connector. $199 or more. You get free PS ground in the content of the United States which is worth even more because shipping prices have not gone down and then $299 or more. We have replaced the Circuit Playground Express which has sold out or is about to sell out with the Circuit Playground Blue Fruit which we did get a shipment of and this is great because you can use it with Circuit Python. You can use it with Arduino. There's a little bit of make code support and it's got Bluetooth for wireless connectivity. Yeah and don't forget especially if you're trying to get a Raspberry Pi we have verified accounts. So sign up for an account on Native Fruit, verify your account via email and then sign up for two-factor authentication. You can use your phone, you can use Linux, you can use Authy, you can use all sorts of things. You can use Ubiqui. And that helps you stay safe and secure. Every single week you probably see all the news about data leaks and more. So getting in a good habit, good data hygiene, two-factor authenticating, all the things you do online is just good practice. Okay, eight fruit live series of shows. That's what we do here every week. Special thanks to JP just did this show and tell. We were watching the show and tell here I think next week is Melissa and then I think we're back the week after. But special treat. They're all great but if you were curious about some of the behind the scenes that was going on at NASA, special NASA correspondent Ann was there and you could see a bunch of photos and more. Launch is gonna happen. Ann's down there in Florida so if there is launch coverage that's possible you might see some on the Adafruit blog. So do watch that on any of our video platforms after this show of course. Or multitask, watch both at the same time, why not. From Desk of Lady Aida, that's a show that we do every single Sunday. Lady Aida, what did you do in part one? Okay, part one. So I did a whole bunch of light and gas sensors, the ENS-160, the LTR-303, the LTR-329, the GUVA and the GUVB. I just showed all the different boards and the testers. I also showed off a little break-up board we made by request. It's a miniature semi-QT hub that lets you connect to multiple boards if you don't want to have them change if you want a little star pattern. That's what I showed off on the first part. Okay and then we do the great search. This is when Lady Aida uses her powers of engineering to help you find things on digikey.com which is a very useful skill in 2022. That's right. What did you try to help find? Oh, so this week you know I was playing around with the DS-4420 which is a iSquared C headphone amplifier that's monophonic and I wanted to find a stereo version and I wanted to find one that was not BGA because most of them are BGA. So I showed a couple tips and tricks on how to filter for like iSquared C when there isn't a specific like search box element. Like it's part of a list of elements and then we looked through a couple different parts and I found a good one actually. I'm going to get some samples. Okey-dokey and JP's product pick of the week. We do that every single week. We have a highlight from it this week. Take it away JP. It is the Metro Mini 328 V2 comparison. That's an Arduino Uno and that is the Metro Mini V2. So you can see it almost fits in the old DIN style version of the chip there. A blink style exercise. So if I plug that in with USB-C and no fiddling around with which side is which. You can see here I have a little blinky sketch that's blinking. I have a Metro Mini and this is right out of the package right. No pins are soldered onto it. And I've plugged in one little STEMI QT cable that is running to a rotary encoder seesaw breakout and then the chain continues. I squared C moves along to this little display. So simple demo here but the nice thing is you can get right to coding without any soldering. It is the Metro Mini 328 V2 with USB-C and STEMI QT. And don't forget to watch JP's show tomorrow on all our channels. And then on Friday we have deep dive with Tim. You can see a little bit of everything going on with the inner workings of Circuit Python. Time travel. I have a few different bits of news this week. I kind of put things in time travel because you know how do you. It's like what happened last week. It's time travel in short time. I'm not convinced time is real but we're still just gonna go with it. Yeah well a bit of an illusion. So this week there was a lot of stuff going on with the postal service. So yeah yeah so yeah I figured I would have this video in case you know sometimes people they'll email and they're very angry because there's other things going on in their life they're like and so you know a couple people were emailing they're angry. We have had a banner on the site. Hey USPS might be down right now. Yeah we also had a blog post put all on social media but you know some folks are. They got stuff going on. I understand pain. So there was an enormous amount of outages for USPS and it's still kind of going on right now. Yeah I have a theory. Okay in the US it was just announced there's no more free COVID tests from the USPS. So you think everyone rushed and got down. Yeah so we send a note to our team because data fruit pays for any testing. Yeah we pay for all the paid time off for vaccination testing boosters new boosters coming up flu shots. You know we want to take care of one another and we don't think that you should have to use your pay time off for stuff like that. So just as being you know proactive us we're like hey looks like if you're if you're ordering free tests if you just happen to have or want them soon it's ending and when you look at the website this is kind of intense ordering through this program we suspend on Friday December second in two days. That's this week. Lots of deadlines going around. Congress hasn't provided his digital funding to replenish the nation's stockpile of tests. Okay well I like how they're just like straight factual they're like yeah what's going on. So what I think is happening because as soon as this was announced and it and it was on the news and everything that's when the Postal Service went down for everyone who uses the Postal Service. I mean look you know I'm sure a couple hundred thousand people all went at once. So here's the thing is it a coincidence or it's a COVID test free day like smartphone free day. Yeah so is it a coincidence maybe yeah but I happen to send out an email to the team hey there is these tests going on I happen to see it on the news and the same exact day from that point for when everyone was saying hey if you're gonna get these free tests the Postal Service started going down and down and down so we'll see what happens coincidence or not it's it's pretty rare for to go down but anyways our team has these alerts and we're like this is kind of weird so I was thinking about like what could it be so that's my guess. It's a good guess. Alright so Eight-A-Box we're now moving into the fall territory so we are squirreling away all parts this might be another thing. So we would very much like to ship the next Eight-A-Box don't forget we don't charge on Eight-A-Boxes until we ship them so don't worry about that but we will probably be bumping into autumn maybe even winter but our goal is of course to get enough parts so we can ship thousands of thousands of Eight-A-Boxes it's easier for some products because we don't have to get like 5,000 at a time and you have to have everything here and have everything and coordinate everything so we're just stockpiling all things we need for the various Eight-A-Boxes and when we ship them we will. Alright next up segment so just speaking of so the chip shortage is still happening but there is a little bit of relief a little bit of a release maybe and so we have a segment that we're starting the real world and that's when we can get parts on reels. Alright what happens when you put 5,000 parts in a tray this week so we do it's actually a tray yeah so we were able to get some parts and it was for Grand Central we got some at SamD51P20s I know folks have been waiting for a long time. Grand Central's are Arduino mega shaped but they of course have a 120 megahertz SamD51 Cortex-M4 processor 1 megabyte of flash 256k of ram these are these are sweet they're great for circuit python they also work amazingly in Arduino you just need a lot of pins and you need a lot of GPIO this this is your lady this is your man and we now have them back in stock so we were able to get more manufactured and get them into the store so it's not not just over but at least one one thing to come in. Okay Mailbag this week on Mailbag these are letters that y'all sent us we read to our team read to all of you novice here about a couple of blue fruit feathers and follow the instructions carefully and successfully reflash the bootloader and loaded my first sketches in an hour props to whoever wrote the instructions we did alright Python on hardware time okay gonna start with some interesting news and then you know big news in our world so this might be a trend and you can check out the newsletter because we kind of cover all the things that go on with MicroPython, CircuitPython, Python on hardware, Python on like Raspberry Pies if it's Python and runs on something it's probably in our newsletter but MicroPython is ending their forums and they're migrating to GitHub discussions that's interesting. It's interesting. So here's some of the features that they say that will be over there it's much lighter integration with the development process which is all those don't get up anyways they could move discussions to from issues as well as tag members for reference and PRs and issues. GitHub discussions has many features for posts and replies, emoji responses, accepted answers, threaded replies, etc. GitHub discussions use much more familiar markdown syntax for writing pros especially for code snippets which I'll support syntax highlighting less maintenance for the MicroPython team more time to work on features easier account sign up and many people who already use GitHub so they don't need to do an account so yeah interesting. So we'll see. Is this the beginning of where a lot of open source discussions are going to live? I mean I think one thing that's interesting is you know and I want to show the exception is that for MicroPython I mean they have a GitHub organization but they really only have one GitHub repo which is the MicroPython repo and I think that makes it a little easier for them to have all the discussion one place there's like if you have a one repo or one project project it's a lot different than if you are somebody like us Adafruit where we have like literally hundreds or thousands of products and we have to like support and have discussions and people need tech support help and we need to have other people we need to be able to like edit and and move and whatever and you know yes there I do see some benefit in it but I think if you're if you're a one product if you're one product or one project organization then yes I think discussions make sense. So we'll see what happens because there's a lot of open source entities out there in open source projects if if github's discussions are going to move things away from mailing lists or forums or there's Gitter there's Slack. Mailing lists are definitely like you know there are some mailing lists but I don't I don't see people creating mailing lists much anymore. So we'll see what happens and then a lot of folks really like Discord real-time discussions on things. It's just really interesting you know it's not that this is sub-stack but you know there is a thing of like oh you subscribe and you pay to comment and I could see that being a thing too in the future where you have to be a member in order to be part of a discussion because maintaining discussions is also it's a it's a mental load. So we'll see this is interesting you know we're going to kind of watch and learn and you know we already do a lot of stuff on github. Like I kind of feel like you have to be you have to have a presence in all parts of the matrix. Yeah. And so like wherever wherever people are most comfortable interacting with you that's one of the things that we that we try to do. Anyways so in addition to all of that type of news and more keeping tabs on trends in the community and open source weekly video shows all the new hardware you're probably saying boy this is like the best Python on hardware newsletter how many have have been sent out 200 congratulations everybody on the circuit python team we are now up to the 200th Python microcontrollers newsletter I think it's the biggest most popular Python on hardware newsletter out there I think it's one of the only ones so it's always safe to say that and special thanks to Ann and all the contributors it used to be my old job doing this but one of the cool things is we get to hire and work with cool people in the community that eventually and I'm working in a different and they get to take over these things so great work and with all the newsletters we're trying to get to about 10,000 subscribers we have over 9,000 but that's one of the goals that we have for this year so subscribe tell your friends yeah delivers every single week no spam we don't harvest your email there's no sales no ads it's not sponsored nothing AdafruitDaily.com it's a completely separate website because we didn't ever want anyone's store account to have anything to do with the newsletter where it was just information like this so that is our vibe okay opens our hardware one thing we just posted this up I figured I'd mention this because we just got these in and you decided to make this thing an eagle yeah well I thought it was you know because JP you know and Todd bought have been doing stuff with these steps which is and JP was like I want to do stuff and he's like make a breakout and I'm like okay as we can JP kind of like he poked and prodded in a kind way and so you know I made the the footprint and what's interesting is it's this is a footprint which I wanted to look like the outline because like the outline wasn't in the diagram really so I wanted to at least batch as much as possible so I wanted to point people out that we do have a really good guide that k-town and I think I helped out a little bit wrote many many years ago on how to make eagle cat footprints but I'm gonna make a little breakout board and then maybe we'll make a little helper or like a feather wing with steps which is kind of fun okay um we have 2,720 guides that's how we measure some of the things that we do here yes by counting them 2,720 guides yeah no no that's engineering what's on the what's on the big board this week all right we got from Tim C foamy guy he wrapped up this game and watch octopus project you know I saw like some retro blog that was talking about like the old watch game and watch games which I had one of these when I was a kid and it was super awesome um but I was like oh you know because of the the sprite like animation um I thought it would be a really good thing to port to circuit python because it's a game but it's like how you do a game where you only have like you know six positions for your character and it's like more timing based um he's a really good job uh for the pie gamer and the pie badge but also it's just how to get assets how to make sprite sheets how do animations you know all that good stuff um Liz did a project that I've been meaning to do I can finally delete my to-do is um unity which is a very popular framework for um making video games or like interactive art you can actually send serial data into it and one thing that you know we chatted about a long time ago was like controlling a unity puppet with a nine-dof sensor and since Liz was already working with this nine-dof sensor for something else I was like hey want to just try like unity and see if you can figure out how to get it working so she got it working and she did a 3d printed cube as well and when you twist it the shape in unity twists as well so I thought that could be kind of cool for people who want to do uh demos or interactive art I know like processing is one way to do it um but a lot of people do use unity so this is really good for like game designers who they want to have like cool 3d controllers um check out this guide you get other sensor data into it shows the the general purpose how to do serial port input into unity um then Pedro did this project uh they made a it's a cute little um essentially an old project that we kind of refreshed it's like a lunchbox shaped raspberry pi server for like ssd media and you can you run like kiwi x you can run plex you can run nfsd whatever you want and uh there's a little mount for an ssd on the side and you can use like a sat at a usb adapter because there's no built-in set on the pi 4 I know that there's the the compute module has it but we want to do something where there was no like you didn't have to really do soldering if you didn't have to you didn't want to use some custom board and of course you can use any raspberry pi although the four is going to be the fastest um then you can plug in ethernet and you get usb 3 so I thought this was like a fun little like portable project um I see more more people doing their own self hosting of video and content because you know you you rent content from other services and they eventually get deleted and like you lose access um so check this out if you want to do your own if you especially if you're already running plex or something similar on a raspberry pi 4 to do your media serving there's a really cute box and it there's a little screen with stats on it as well and then jeppeler updated the capturing camera images circuit python for esp32 we are now using the esp32 cam module um it's like 99 percent the same but we we use their uh configuration initialization code okay it's time for some factory footage as promised we're not going to show the disney building being built anymore we're just going to show electronics getting made so here's a quick uh time lapse that we have lady aida making a prototype or something on our desk or something around here okay it's 3d print in time got a couple of videos we're going to play this back back we've got this cool raspberry pi project and then uh you guessed it another 3d printed skull related project because that's uh that's kind of how we roll skulls skulls yeah black t-shirts and skulls usually okay you can build your own media server using a raspberry pi and parts from ate a fruit the raspberry pi 4 is a great platform for streaming content and can be used as a media server store all of your media on an ssd and use it as main storage for a significant speed boost in performance a sata to usb 3 cable can be used to gain faster transfer speeds of up to 50 megabits 3d print a pc tower inspired case to house your pi and some extra goodies for a fully featured build you can install plex and stream live tv and movies including services from netflix disney plus and hulu just to name a few use a 1.9 inch tft to display your pi's ip address cpu temperature and even disc and memory usage using circuit python libraries you can easily write your own scripts to display all sorts of content you can even display gif images and use the built-in buttons to cycle through them featuring a metal arcade button you can use it to power down your pi it's good practice to safely shut down your pi to avoid corrupting the disc pressing the button when it's shut down will automatically boot up in kiosk mode and enable the tft display download the files and follow along with the tutorial to build your own by hitting over to learn dot adafruit.com we hope this inspires you to build your own media server using the raspberry pi and parts from adafruit learn how to make other skull based 3d prints every single week at adafruit uh with 3d hangouts at noveira so before we do uh i an mpi i don't forget the codes nudes nudes and the reason is nules nudes let's do some ion mpi this week's ion mpi is from kemett lady aida what is your pick from digikey this week for ion mpi and glad you asked we got this this is um a series of sensors from kemett they are the trs uh series of thermostat sensors and what's neat is i actually learned a lot writing this ion mpi because i didn't i i misunderstood how they worked i'm going to explain to you how uh these sensors work so these are sensors that basically they're in like every appliance you know and essentially they're a switch that when you hit a certain temperature they either open or close so let's say um you have a heater blanket or something um obviously you don't want to get it so hot that it could burn you uh so there's a there's a thermostat um but maybe there's also a safety interlock you know if the the heater blanket gets too hot the connection opens uh your heater blanket no longer gets electronics electricity through it and it turns off um you know likewise you could have an alarm in your freezer the temperature goes below or above a certain point it's you know either gets too cold or too hot um an alarm goes off and you're notified and that could be done with this very simple switch no firmware coding required um so there's the the thermal reed switch uh series so it comes in a couple different packages and we'll show you this and there's multiple different ranges so each one has a set point uh that either make or break below or above that point so um the make ones you know when they uh go above the temperature they make the connection the break ones when they go above the temperature they break them whichever make above make above break break uh and they come in different sizes and shapes with wires or not or you can solder them onto things i got a couple that were um solderable and this is interesting so you know i was actually i thought that these kind of worked like ptc fuses which we had talked about a few you know weeks or months ago we covered a couple ptc fuses where the material as it gets hotter um the resistance changes but actually these um use the curie point um like the scientific the theory of the curie point which i remember from like high school and college so this is a really neat thing basically you have some magnetic materials um and you know you have all the spins going in one direction and that's what makes you know there be a north and a south pole to um the material but then you know sometimes you know sometimes you hit a material it'll scatter um the crystal or if you get it above a certain temperature and what's interesting is it resets like if you you heat it up to a certain temperature and then the crystal kind of breaks apart you no longer have this magnetic property it doesn't act like a magnet and then when you go back down it reforms into the crystalline shape and the the magnetic property reappears um so what these sensors do is um they have a special material that the thermo thermo right which is tuned by chemet to um have that effect the curie point at like 15 degrees c um interval so it's like 40 55 65 75 whatever and you can see in the graph they have you know the different points and it's like a really hard stop like when it hits that point it really does like turn from a magnet to a non-magnetic property almost instantly so inside all of these sensors is basically a reed switch which a lot of folks here have probably used before this is a generic reed switch that digickey stocks and the reed switch has two metal plates and usually uh and there's they're in a glass case or you know some other case that's totally got in inert gases there's nothing inside there's no oxidation that you have to worry about and when a magnet comes close um the magnet causes the two pieces of metal to touch to make the connection or separate uh to release the connection and so we've used these for like door and window sensors you know when when the magnet comes close it closes the connection an alarm goes off or vice versa um but with a little bit of clever hacking you can turn these into temperature sensors um so this is basically how like a reed switch works normally in the top right there you've got a you know a a magnet and it comes close um and the two pieces of metal touch each other and there's a a magnetic field um on the left side I mean this a diagram is from the data sheet this is good but I actually like um let's get we'll skip ahead because I'll show the very nice diagrams so there's two types and basically they do like a thing where the outer ring is that thermo right that material which I get is a magnet until um the the temperature rises a certain point and then it becomes demagnetized um and um for the brake type the the thermo right's in the middle and there's permanent on the outside and on the make type the thermo right's in the center and then there's a little bit of a spacer and I'll I'll show you the video also because it's kind of interesting um the how this hack but in the center is a normal reed switch okay so for the brake type I thought this was I mean they're both they're both kind of simple to well simple but they're easy to understand so there's the reed switch on the inside and see there's on the center there's the pink thing which is which is a cutaway of the ring and at the low temperature the middle part is magnetic and so the two permanent magnets on each side there's a continuous field that's not broken and so it it's the reed switch is closed and then when it gets very hot um that center part again becomes amagnetic the pink part basically acts like a open connection and there's no transference of the magnetic field through the material anymore the magnets no longer right next to the magnetic field is no longer right next to the the two reed switch leaves and they open up and now the switch is off and then when the temperature goes back goes back down it re-magnetizes the field flows again and vice versa so like no power is required no sensing no code it just magically happens at the curie point um likewise the make type uh is sort of similar except there's you know there's two thermo right rings in the middle and the magnet and basically the same thing where it's like you want to create or remove the magnetic field which would connect or disconnect the reed whichever whichever way you want i mean usually people have a break switch because your toaster oven it gets too hot you want the electronic the electricity to disconnect and these come in multiple different shapes there's also the ohd family which is like sealed and comes in like this epoxied enclosure and that's uh for u l c s a r t u v rating um there is u l rating for looks like one of the lead terminal ones but these you know you can use these for anything again they're very simple they just kind of work um physics seems to have not let us down yet uh so far and so you can rely you know you can rely on this knowing that there's not going to be any like funky weird you know watchdog timer that has to go off or like oh what if you know the the ptc thermistor isn't like you know it has some leakage current like this opens a reed switch it's open it's open like it's there's no electricity passing through um there's just some things that you know they they show what they're they're used for you know refrigerators and rice cookers and uh water and whatever you know there's there's basically two use cases i think of that are really good one is as your main controller i mean these these could work as a great sensor input into a more advanced mic controller um you know you definitely you don't have to you can just have a switch and it would uh activate interrupt or or what have you just you just know whether it's above or below the temperature but it's also great as an interlock you know you have a more complicated feedback system but then like if that feedback system fails for some reason you have something like that protector element it's like no matter what it will never get above this temperature because if it did uh the electrical the electrical connection would open and if you're not sure which one you want there's also a kit that did you keep it together with kemett that has like kind of one of each make and break and various temperature uh trip points the curie points uh so you can pick up this kit if you just like want one of each if you don't know whether you want make or break type or what the temperature rating is um and these are the parts that are in that kit so you get like you know from 50 degrees up to 120 degrees half make half break all of them can pass um 100 volt ac and uh looks like about 0.3 amps um so good for a signal or even low power available did you key and because we're showing this means it's in stock it is in stock um i got a couple of them but there's um there's like every rating is available you know it's like i actually really like stuff like this because i feel like you know i spent so much of my time in like firmware and like firmware is great but like i would never trust it with my life um with my safety whereas i would trust something like this it's like it's the curie point it's physics like it's reliable i i believe in physics yeah all right and uh we have a little bit of a video that has some of uh information about they haven't very nice it's much longer but we have a little snippet yeah let's shift our focus to the operation principle of the thermo sensor simply put it is a thermal switch that opens and closes the contacts within its built-in read switch by the shift in magnetic energy of thermo right and permanent magnet here a ring shaped thermo right is in the sensor sandwiched by two ring shaped permanent magnets with polarity arrangement as shown with the read switch fixed inside the rings when the temperature of the thermal right is at or below its curie temperature it functions as a magnetic body in contrast when the temperature exceeds the curie temperature it becomes a non-magnetic body this change in the characteristics shifts the magnetic circuit which makes or breaks the contact in the read switch the thermal sensor has two types of switching action break type and make type the break types mode is normally on that is turned off at the operating temperature as opposed to make type which has a mode that shifts from off to on okay um we're going to go off to new products there's some things ahead that'll be revealing let's kick it nudes nudes nudes nudes nudes nudes nudes nudes nudes nudes nudes nudes nudes okay well first up um not all nudes only the freshest nudes yeah uh we do have one update it's technically a new product but it's assembled version of our seven segment led backpack if you do not want to solder led backpacks you want to get them ready to go plug in with stomach qt connectors uh we now have them in stock yeah and uh you could see a few different things about these yeah so it just comes assembled yeah so it looks like on the front about them too is you're like oh i remember these from previous show that's right um we had the red ones web page and we have you know all bunch of different colors we had we had we're we're soldering each one and as we get them so we had red last week green we got done this week so we're gonna get more and more colors okay uh next up okay these are not technically nudes but they're they're still filaments um so this is a non flexible led filaments let me actually get all these filaments out here because they're we're gonna jam through them um so these are again used in like led light bulbs or Edison bulbs or like other illumination but they kind of look just look like little led neon tubes um and these are the non flexible ones so you can see they don't they don't flex and move um but they operate the same way basically you give them three volts um on the anode and cathode about 50 you know milliamps or so and they light up really bright and these are um i will say if you go to the overhead yeah i'll go to the overhead i mean they're incredibly bright they're so bright you can't even really see them it's if i disconnect i mean it's it's well it's bright enough um these are not just decorative like you could actually light up an area so i mean good if you want to make a light and um you could of course pwm them um but they're stiff and they've got this like soft oops the cameras does not like what i did dioramas and stuff like that that use this or yeah there's a bunch of ships and stuff ships yeah too much light yeah my mic oh yeah oh no do you want to use my mic no okay we can come don't worry i have i have plans with implants okay uh sorry so you get three of these um and they're very bright of course you can chain them one after the other and you get you know you power with a nine volt or whatever um but these are not flexible so just be aware of that i wouldn't even bend them to be honest inside are these led elements and what's nice is that maybe you could go to the front camera because i'll light this up because it's so bright the light's really the light is very uniform um so unlike the flexible nudes that have they're bonded onto um like a little flexible piece of metal um these the light is like it looks like a filament the light is a hundred is 360 degrees all the way around you can't see any gaps or like flickery notes or or darkened spots okay and then um i had a couple close-ups of this yes all right and such solder to the little metal yeah so um of course you know we mentioned the code for the show and everything but uh the star of the show tonight besides you lady our community our customers our entire team here at a fruit our nudes nudes well i'd like to show off some nudes yeah so um we've got a lot of nudes um we've been sending nudes to people we've been getting nudes and uh looking forward to seeing these nudes yeah okay so we've got basically 300 millimeter long noodles of flexible led filament and these are used in i mean they're basically used in like light bulbs that have funky shapes in them like you've seen light bulbs have like a little ghost or star or heart and this is what they use and they're flexible um and you know there's no rating on the flexibility but basically it seems like you can kind of flex them as much as you want and as long as you're not like pinching and cracking them they're good to go um with the red one you can see just because red one is really covered with a dark i mean it's still quite bright but it's it's covered with filament you can see that there is a little bit of each like little diode element you can see the um the point light whereas with the green blue white and yellow they're really bright and so you don't they kind of blend together but this is kind of what like we always wanted el wire to act like you know we got wire for the first time this doesn't make a high pitch noise either it doesn't make a high pitch noise it uses a lot less power yeah and i wanted to show yeah and you know that when they're off the colors do look different of course so that's green and then you know blue the blue actually has blue led elements in it looks bluish yeah and you know the other ones are tinted like they're you know obviously red i was interesting red does not use um the red i think maybe has red elements in it but i still you know you power off of three three volts um but the warm white and the white and the blue yeah all like native colors and then pink is white i think it's cool white with like a pinkish plastic will it tolerate 3.3 volts well i mean there's a forward voltage of about three volts you want to use a choke resistor i'm not using one here because i am just doing a live demo but um you should treat it like a led right it's a very long and thin noodley led but you do want to have a resistor so you use like a one k and then you power it from five volts or whatever you figure out the forward voltage and then the the current draw which is about 50 milliamps um you know i'm i'm basically powering them off of my 3.3 volt supply but it's not the right thing to do right you're not supposed to do that with an led um you're supposed to give it a choke resistor to current limit because it's a current device on a voltage device um so that said they're they're you know super flexible they're very skinny um you can thread them through clothing you can um twist them around something you can shape them you can glue them down yeah there was a lot of different tie them in a knot there's a lot of different types out there and you can get these on ebay and you can get these elsewhere but it's uh like gambling um someone even said in the chat they're like you know 60 of the ones they've bought just don't work so no we we found a really good factory and yeah we basically got these made for us in the shapes and colors and yeah so you know ours are this is what ate a fruit does these are high quality nudes yeah we have high quality news and then just you know on cheap nudes yeah and then one quick uh note you could go to our page for the products and you can see you know which which ones we have and we have a bunch of different colors so you want to get we can go to the overhead um yeah i just don't know how we'll just show up yeah so it's blasted it's just pink yeah it's really cute so one thing about the nudes to be aware of is um you can see the the substrate gridding so there's like two thin wires and then in between there's these little dots and those are like micro leds and the leds point out so there is like a front and back side to the noodle or the nudes and the front side which is this part is going to be much brighter than the back side because the back side is going to have like the refracted light but it's not going to be shining out so again if it's really important for you to have like perfect 360 degree light for you know emission these i think have double sided it's hard to tell or they're just really well diffused they look like a pure tube of light whereas these are somewhat direction how would you chain these together you can you just need to then you know add the voltages up so if you add this one to this one you know you chain them together now you need six volts because each one is three volt forward so it's it's basically just like chaining led you can chain as many as you want as long as you add three volts per and then you still want that current limiting resistor but yes you can chain them yeah you can't cut them and solder them though once you cut them you're never going to get to that little that little metal bit in the middle i mean it's just so fine i don't i don't think it's worth trying to get to i think you just get the length you need and then figure out how to make it work for you and uh don't put these on cats whoever suggested that in the youtube chat don't do that wow don't do that maybe your cat looks i leave you're very bright though um right so they come in yeah yellow and so green and red and the warm white of course is the yeah the most popular and then the warm white we also have it in a shorter length yeah so thanks for checking out our high quality nudes here at Adafruit that is this week's new products so uh anyhow um i thought we would answer some questions soon but i would do some top secret i show i'm going to show a video and then show you a little bit of like how we came up with some of the product naming and logos i think we did in the past but now that the product's out um we wanted to show some of that so go post your questions in discord and let's do some top secret okay first up um if you have a raspberry pi pico w circuit pythons on the way here is a glimpse a glimmer a preview a premonition of the future really what is this well this is a raspberry pi pico w also known as a pi cow and this is the board that raspberry pi just came out with that has an rp2040 and um a wi-fi bluetooth module built in and it's really cool and this one's got a special thing going on when i plug it in you see that led that's blinking yeah well that led is actually controlled by this module so if i want to blink this led i need to have firmware that's talking back and forth here like communicating to tell us for more to blink the led and this is not micro python this is circuit python as you can see here that's right so we have started on a build for the pico w for circuit pythons it's going to be the easiest way to do iot and we've just got the led blinking and there's more to come okay so um this is the logo for nudes and we wanted something that conveyed the the noodle like nature of it led signs and more so i wanted to like show our work with this so in new york city pretty much where i walk in the morning so i i walked to china town there's a there's a place i go down there when i go for a walk and um there in back there's a bunch of noodle shops uh some on the outskirts summer um you know pop-ups that come up once in a while this one was nudes nyc and i thought they had like kind of a cool looking logo i'm like all right and this is called nudes in the city and then um this one was send nudes and this is on mot this is uh one of the places um i walked to and um they've had pretty good noodles and then here's an led sign or sorry neon sign and i was like that looks like leds and then this is like the third one yeah and then a lot of nude places and then there's shirts that are for sale down by canal street that's a sand nudes and it's noodles so the idea was like how do we capture the i the there were noodles are referred to nudes but it's also kind of you know funny and then we also wanted to have something that was like neon and led looking and kind of the steam coming off and we also had some ideas like maybe it would be a sign um and you could see kind of the evolution of this and we the the bull definitely kind of stuck and then we said well you know there's also maybe we could have something like a light bulb to show lights and then we just settled on you know these these two and then um this this logo we're starting to do more animations with our logos because i think at this point everything's a screen and a battery yeah and and everything's moving or can be moving um sometimes and so that's um that's the evolution of of this and it's been something we've been working on for a while and uh them's our nudes it's a nice design yeah that's a secret okay we're gonna do some questions yeah um the first question tonight will be what is the diameter of the news they want to laser cut a channel to fit will there be a spec sheet oh they want to know how thick my nudes are pretty thick um so they look like they're about a you know millimeter like two millimeters maybe um i'll measure them later um so what's funny is there's not a spec sheet because again this is these are meant for like we basically contacted the light bulb factory and said hey can you just like send us these without the light bulb part we'll get i don't know if we'll build a spec sheet but we will be able to um we'll measure these with some calipers but they look like they're about you know 10th of an inch all right some folks are posting up some really interesting projects that's one of the the skeleton yeah the stick figure one so i think we'll see some interesting things you know you could probably take these nudes and put them on um like a little robot and then um turn off the lights and it would be you know yeah i mean one of the nice things about these is like you know they're pwm controllable and we have like the aw 95 23 which can do 50 milliamps per channel um so it'd be a really good way to control these nudes and pwm them uh to get dimming effects which again you can't do with el very easily it kind of sucks to eat dim el um and also it's very like noisy you get a lot of residual audio effects yeah and a lot of folks are already coming up with their um projects for this so yeah obviously wearables this is gonna this is gonna be great for wearables extremely helpful for almost every costuming project because they're flexible um and uh yeah tron cosplays and or anything like space themed or futuristic also small models yeah but even also like fantasy like you want to have a glowing effect like the warm white has a very warm feeling to it and it's like you could fit it into a very small space if we have those individual um 06 or 3 leds which are good for models but if you want to have like a curved effect um yeah again these can fit anywhere they're extremely flexible yeah being nudes and um a couple more questions and as you all ask questions if it's not on the product pages uh this is always helpful for us too because we can continue to add and we're gonna probably do yeah we're probably going to do an uber guide because this is probably going to be like new pixels a little bit where everyone has something a good resource a good supplier us and they don't have to um kind of do a lot of guess work and waste a lot of time yeah people will have to know what to do with these nudes yeah um you want to know where your nudes came from um any suggestions for constant current driver breakout or chip to use with nudes like these um like i said the aw 95 23 um b which we stock is a 16 channel constant current led driver um so that would do a very good job it could do pwm and i believe it is current limited although like i don't remember off the top of my head um but i do remember it can do 50 milliamps because um i was using it for a backlight and i was like yes i can do uh 50 milliamps uh whether or not i would trust it to do constant current limiting just put a hundred ohm resistor in the middle what are the nudes min type max current they are rated for 50 milliamp usage so you know constant current drive them with 50 milliamps of course you can go as little as you want you can probably drive that a hundred but you're just it's just like over driving led like you could burn it out you could lower the life cycle of it you could eventually would dim they're micro leds i don't you know i i haven't used micro led elements before um we have a couple flexibility things that use those little micro diodes um each one uses very little current but then together you know you you add it up and you get to like 50 or 100 well we autograph the nudes might be hard very tiny to but you know what you could do is you can make your own signature out of the nudes um next up are they are both the 130 millimeter and 300 millimeter 50 milliamps yeah that's actually the spec which is odd you'd think it would be different i think it's actually a self-heating thing um maybe because that is what was told to me by the factory but i you know these are very experimental avant garde nudes that we're getting here um so well you know i might have to do some more experimentation but i think 50 milliamps is a safe bet also that you know they tune they tune it i think it's like they're both meant to run off the same driver so yeah i wouldn't be surprised if you still get 50 milliamps for both of them even though the one is a lot at least twice the length let me see if i can find yeah i'm gonna go over to the thing so one project i i would like to see someone maybe consider making out i'll ask this question why i'm going over there uh yes would be a good replacement for small neon signs model train stuff yep any chance for short nudes uh 26 millimeters and more colors and temps if this the not the non flexible ones um they kind of didn't make them it's interesting is you know when we later later went to like a lighting store we saw what these are used in these light bulbs and that the longer ones are for like these kind of decorative fun light bulbs and the shorter ones are actually for illumination so um i didn't see them i mean i could ask to get them made in of course different colors um i would honestly just say like paint it or cover it with a gel or something to to change the color it's white so you can kind of paint it any color and it will it will light up that effect or you can gel it um but they're they're much brighter it's they're actually kind of two different products the flexible ones even though they're both from the same factory they're they're they're used for different purposes one is for illumination one is for decorative um effect i've been silently watching for a little bit just want to say you just thank you to the work that you and native fruit community do at circuit python thank you you know we have a blink of chef that has um uh you know cooking spaghetti so one project i'd like to see one of us do this is one of those times where i'm just like so you know running a native fruit means i don't get to a lot of projects but luckily i get to work with a lot of people so i might ask one of the team members i might assign this um but there was a i really liked this episode of star trek next generation called emergence and there was this um you know this the computer got smart and um let me see if it'll if i could find a photo that's uh uh that's photo that's wow that's a lot of text well you know here people got opinions yeah you want that image yeah i just want to show the image of this how do i you know it used to be easier they do not make it easy to look at images it used to be easier to show images let me check to go down and go here okay yeah so that's a cool that's a cool like you could make a little a little miniature one um i think there'll be a lot of neat things inside of like case mods you could do something you know you can even power them with like the smallest possible battery so you could do a lot of neat stuff with it so yeah vertiform city here we come we have some star trek fans there um okay uh well the needs have an holy fans page you'll have an only fets page only fets only fets only fets only your field effect transistors are permitted let me like your french nudes okay uh and then can they be cut shortened no i do not recommend it philby had some surgery on the nudes it's really not pleasant i wouldn't do it i would just just use it as it is it's very very it's it's not easy to solder to that metal so talk about had a really uh good idea as usual um so i have a straw at home that was like um this might be a way to do this and i'm just not gonna have time so um for crafty folks out there if you get one of the you know curly straws um you could probably put the nudes through there that's what it looks like yeah well look this was the 90s man we didn't have a lot for practical that was like what we did for fun it was like oh a crazy straw yeah so let's see if we got any more yeah only fets and now there's other things so you know what a great time to be alive because there's so many um i guess popular shows and more that that already use like eight of fruit neopixels and stuff and we've seen these type of things and now they're finally available um these little led noodles so i'm really looking forward to what folks build because there's so much inspiration that you get and then there's also a lot of things that haven't been made yet um because this was just really hard so um i think with that yeah uh we'll oh sorry i'll do this we'll quick it drive the nudes and do they get hot to the touch we you know there is a pwm driver the pc a 96 85 which might be able to drive these but a quick it's better for motors it's not really led driver and do they get hot to the touch they do get a little warm especially the um the short one it's it's quite hot dense so it doesn't get quite hot warm nudes warm okay nudes all right and uh them some questions this week okay nudes nudes nudes okay a little bit of a reminder um you know what the code is of course how could you forget these are gonna sell it really fast so um you probably you should probably buy them um this hasn't hit social media we kind of wanted to wait so the folks that are watching live could see them right away and um i'd like to uh thank many of the noodle places in york city that i've stopped and eaten at that has inspired and fueled a lot of ate a fruit yeah and i feel like this is uh you know one way um that we can uh also say thank you a portion of um what we sell at a fruit you know we can hurts to nudes we we then yeah we we buy noodles uh that and then we and if you feed lady ate a noodles electronics come out it's true how tight goes in yeah signs come out so all right um it is down yeah so that's that's a show for tonight i think specials thanks jesse may who's working behind the scenes i think um special thanks to all our customers our staff our community everyone who's been hanging out together um this is joyous stuff um i don't think you can you can do things like this unless you can imagine all the people out there that are gonna have them and use them like all the stuff that we we get to do now we get to imagine all the neat things that that y'all are going to do with it so it's a special well it's a special treat because not only is there a you know a product that you can work on and things but there's also all the things that you can imagine people are going to do with it and that's kind of a special treat you know all the things that we make we're like oh this is going to be really interesting to see what people do with it and um thank you everyone for fulfilling that part of a product it's it's a physical thing but there's also this other thing that um it's just what's in our imaginations and that's kind of cool so we'll see everybody next week i might have this part of a giveaway we'll give away some free nudes yeah i really do want to have a banner that says aida fruit sends out free nudes with every order i do want to do that um so we'll see everybody next week this has been an aida fruit production here is your moment of zener and on the way out we're gonna have some more music and some more uh factory stuff uh kind of like from the beginning of the show we have a lot of factory footage we're going to be showing so enjoy it
