Hello readers of San Francisco Public Library. My name is Candy Goorley and I am one of the authors featured in the Filipino American International Book Festival. I live in the United Kingdom where my book was shortlisted for the Carnegie Medal and the Costa Prize and here it is, Bone Talk. It is 100 years ago and some cut is 10 years old. All he wants is to become a man like his dad with his own shield and spear and axe. His best friend, Lukey, wants the same thing except Lukey is a girl and in their village girls don't grow up to become warriors and then another boy turns up and he has news there are strangers on their way up the mountain the strangers are called Americans and they are bringing war and death. Bone Talk is set in a bit of forgotten history but it's also a ripping adventure. You can check it out at the San Francisco Public Library or order it from your local Indie Bookshop. There's more info on my website. Scan the code. Happy reading.


Live from New York, it's Ask an Engineer everybody and welcome to Ask an Engineer the only live broadcasting Adafruit electronics show in the entire universe And I don't know many other unless there's a multiverse and then you're watching this on repeat. Yeah I'm Spider-Man But yeah, it's one more last shows of the year. I have one next Next week we'll see but it's me lady Ada with me. Mr. Lady Ada on this cold cold short dark day That just means there's more time for nighttime electronics And that's what we're gonna be doing for the next hour We're gonna be checking in with all the news videos updates products and more. We've got discount codes. We've got it's not out yet We've got top secrets and Cool 3d printed shoelaces. So yeah, let's kick it off. Mr. Lady Ada. What's on tonight show on tonight show the code is PADC PADC 10% off in the A4 store all the way up to 1.59 p.m. Or until we remember turn the code off like it's 10% off in the A4 store Use it or lose it Good talk about you for it live. We had our show and tell we have from the desk of lady Ada We have a little bit of a highlight from part one and part two including the great search where you can learn how to Search for the parts you need got a clip from GP's workshop We show the product pick of the week That's JP's pick of the week that we have an automatic discount that automatically applies. We do that every week We have some made New York City factory footage Got some 3d printing videos and IMPI this week. It is analog devices brought to you by Digikey. We got new products We also have some top secret We're gonna answer your questions We do that on discord adafruit.atc.discord or discord.atcGT slash adafruit all that and more on you guys to ask an engineer So let's first try some stuff here. That's new. We're broadcasting on Instagram this week. Hello Well, they it's a new feature that we're allowed to broadcast live. So the only thing is it's in They're they're gonna eventually have it so it can be portrait or landscape. So I get really yeah, you know Maybe you can listen to it like a podcast. Okay So anyways, thanks for joining us on Instagram We broadcast on all the places because some places are better than others some people have preferences So anyways, welcome aboard folks on Instagram. I put the discount code in there, too So folks want to save a buck or two Let's do Some housekeeping stuff and more in addition to the discount code lady. There's free stuff. We have freebies Still $99 or more when you order at the Adafruit shop We've got this beautiful PCB coaster comes with little bumpers So it doesn't scratch your desk and it protects your desk and it's got this gold Adafruit logo on it and it's like an extra thick PCB. So it's great $149 or more orders get a free kb2040. It's an RP2040 chip My controller board that's the same pinout as a pro micro and it's got all these cool accessories like lots of memory and buttons and Stem acutie and a neopixel and eight megabytes of RAM. So it's like a little controller board to build projects with and $199 or more you get free UPS ground shipping in the Continental United States and $290 more we've got circuit playground express is still yay The part shortage is really over because we've got lots of these our favorite all-in-one development board Featuring the samd21 it can run Arduino or circuit python or Make code or code.org. She has discoveries or micro python arrest or micro list or whatever It's like a really popular chip with all the LEDs and sensors and buttons and stuff builds into it So you don't even have to do any soldering It's a great way to learn on comics and do check our site because for the most part If you need something for for Christmas order it next day air I'm gonna probably go out like tomorrow and then maybe in our Friday But that's pretty much it if you're saying oh my gosh, oh my gosh, oh my gosh Don't worry get some gift certificates We don't have ours expire So if you want you can get an eight of fruit gift certificate if you just show up late to a party You could still do it from the phone. They never expire you email them to the recipient and You're good to go. They use them We're pretty good rate of like we don't we're not like Starbucks or real life make money off it It's like yeah use them people get stuff and it's just convenient Okay, and then big news So when we made this graphic and we said wow eight of boxes totally gonna come back in 2023 well It turns out it was a long year of chip shortages supply chain issues world and local and every type of geopolitical Nightmare you can imagine for building things 600 almost redesigns 571 571 So here's the good news. There is a small number of you You're getting emails tomorrow the subject of the email Because I'm gonna link to this video in the email because I get it. There's fishing scams. There's Social engineering that people do people know that like no you want a box and use they're gonna use that knowledge Yeah, every day. There's another giant scary thing about you know Someone pretended to be someone so they can do something I get like weird texts It's like your packages ready and who knows so we want to make sure so you're gonna be getting an email from supported a to fruit.com That's important. You can double-check. We did the Google verification thing shows from a to fruit Most people are getting their emails the Gmail usually in some form And the subject is exciting update a box 21 is ready to ship update your details now So like I said a small number of you we wanted to get some out by the end of the year And then of course, we're ramping up to get all of them out, but this is how we can start Short version login tier a deferred account and update any shipping a payment info link to your eight box subscription You have an eight of box 21 that will ship before the end of the year So we've basically redone how we do everything with a to box to accommodate to thousands and thousands of people And then the signups that we want to be able to add later In context of the biggest drought of parts and just like moving stuff around on planet Earth over the last couple years So, you know, thanks for everyone who's been patient with us. Thanks for sticking with us. It's one of the only if only Electronic subscription services out there. We don't charge until we ship So for the folks out there that maybe you move here Maybe you have a credit card that you have to update or whatever form of payment that you're using when you get this email, please Log into your account Good a deferred you can even do right now if you're if you're just an eight of box customer in general because these are going to be coming Out our team is going to be taking a little bit of a break for the holiday But we're getting a few out and then we're going to resume and Continue to get all of them out until we're completely done And then we're going to be able to add more eight of box subscribers And then we're gonna have some more exciting changes with eight of box, but we're in a really good spot Thank you so much. This is the eight of box video that I'm gonna slice up and also put on our site So, you know, it is from us. It is happening Okay, it is shipping 2023 a few of them, but they are shipping. Yeah, it's happening. It's happening. It's happening It's happening happening happening happening happening happening. I can't wait till we can look back and say it happened It happened. Yeah, okay. We do a bunch of live shows including this one and show until which we just did Okay On the show until this week Lauren stopped by eight for an IO did some Blockly stuff Easiest way to do no code low code ways to get your IOT projects up and running. This was a cool developer preview It's still not live, but you want to see what it's behind the scenes? Yeah, it's behind the scenes. We showed just about everything Um, gp showed off a cool camera project. This is using the momento camera our momentum camera is I think the only open source Our camera certified runs python. Yeah, I think it's one of the few if not only Um, gp showed this off and you can learn about making your own photos changing the led colors as you take photos and more Liz had this really cool bff squad. It's I know. It's so cute these little Yeah, you can kind of um, put them on like a almost like a lego or a like a, you know 100 in one electronic learning kits. Yeah, it's kind of cool. And then um, we have Jepler who showed off beautiful fonts using circuit python or quali board and this like really neat bar display And then kyle came by with one of the cutest most interesting amazing functional and scary Robots it's a diode cutting machine that cuts diodes it does 10 at a time or 55 or whatever you want And kyle has a cool keyboard company and this was um project that he made to help him produce things and we've Showed how we do testers and stuff. So this is nice to see Makers helping makers showing what type of things they use to run their businesses. Yeah, I think it's good It's going to be on github and more and we'll get the word out about it. Very cool project Okay, um, let's go to the desk of lady. Are we do this on sundays? Uh lady, it's in two parts. Yeah, what did you show this week on your desk? Um, okay So I was debugging this non-working e ink feather wing and it turns out that I swapped some component diodes for The exact same component number, but it was different manufacturer and actually didn't work So I talked about debugging that like why it took so long and how I determined that it was a diodes I also showed off um A panel of boards that was manufactured with the wrong resistor And what I learned from that and then a prototype that had the wrong size capacitors And what I learned from that and then how I picked the right size capacitor So a lot of you know, it's three projects that weren't working at the beginning and worked by the end Wonderful, you know people like to see like Like it's not always a hundred percent perfect every time. I make mistakes all the time. I learn from them Maybe you can learn from me too skip skip the learning part. Yeah To show the mistakes because we feel like with a lot of things especially with electronics. No one is um showing That sometimes there's mistakes, but the way that you fix them and handle them and what you learned from it It's kind of that's the game now. That's what matters most. Yeah Also, we have The great search. This is where lady that helps you find the things you need to find On a site like digikey.com. There's millions of millions. Yeah, and I use one on one part Yeah, and I was reading, uh, you know, there's more like The world is a little weird right now. There's a lot of emphasis on Certain types of startups, but people are building a lot of hardware, but they're also um using tools to help them learn And one of the things that's lacking out there is well I want to learn how to use a search engine a site like digikey. You're not going to use google to find stuff on digikey It's not possible. Um, so how do you use Something like digikey and how do you use all the filters to find the parts? You mean especially over the last year plus with part substitutions So you do the great search. What did you pick this week?  I sprinkled them all over the place um, so the video I did was um packages um ceramic um Uh, what's it called not electrolytics, uh, the difference between ceramics and electrolytics and tantalums substrate Numbers like x5r and y5v what you know when to use which one um percentage Variability and bulk Uh, capacitance derating based on the bias dc voltage Stuff you need to know because a 10 micro farad cap isn't actually a 10 micro farad cap when you're using it um on a power supply, so You'll want to look at how to derate it properly and then you know, I just use twice as many or you pick twice as much um capacitance Not too bad, but you do have to look at the spec sheet for that So I just showed how to do it, um real quickly and then we picked, uh, you know a good general purpose like one cent 10 micro farad cap that I use all the time and I recommend to others okay And then Just as we do jp's product pick of the week here is this week's highlight Is the ads 78 38 channel 8 bit adc It's an analog to digital converter I have two of these so that I can gang them up Each of them is reading eight of the faders and then those messages are traveling to my microcontroller over I square c this is just purely a midi fader board and then I'm reading in usb midi messages in software to control this little Um mixing board that you can see here pretty stable Signal not a lot of jitter in that sometimes a little bit just because of the the mechanics of the faders But you can see here. We've got some pretty stable smooth it's very responsive type of Reading on those analog inputs my product pick of the week this week. It is the ads 78 38 channel 8 bit adc With stem aqt i square c Okay, and a reminder jp's workshop is off next week jp b off for a couple weeks I don't know if there's a deep dive this week with tim do check our discord channel and of course all over our social medias Um, and then i'm not sure we'll see because uh sunday is uh christmas eve So we'll see if we're doing a desk of lady and we might just post up some videos l depends like you know, uh If we can have something interesting to show y'all we'll do it otherwise. We'll let you know Yeah, we'll take the dance. Yeah, we'll see go sledding.  Um, we have a new segment series blog post and more. This is whipper snapper wednesdays. Um, this is uh From bret and our entire team Um, the news and the things to look at this week. You can go to the blog This has all of it. It also has an arrow blog You can look at the new component picker beta 74 and more sensors. So the component picker Um, this is what you can type in You can say, um, what you're looking for. Yeah, and it will um auto filter them based on what you type So if you just kept in humidity, it'll show you just the humidity sensors. Yeah, you can type in ht20 I'll just show you the ht20. Let's say if you wanted a humidity sensor to Send you an email when the humidity got to a certain amount This was one of the ways you could start and uh, we don't care if it's our stuff or not There's other things inside of correct. Um pay to fruit i o and whipper snapper other Um vendors, um, we just want to have the easiest iot service and no code low code So with um 81 plus components, there's 82 We needed a better way to filter all the stuff because there's a lot. So um, yeah, it's hard to scroll 82 is a lot. So, um, just tons of optimizations. The search is in there and makes it really fun and easy And you can you know hit different keywords from buzzer button for sensor types light temperature pressure interfaces vendor It's in there and then the latest version of whipper snapper at a to fruit i o it's beta 74 for 1.0. Um, do you check this out? It's on github stable release and then we have works with whipper snapper um in the Beta now, so these are the things that works with and we have a way to indicate that As well and we're working on our search on our site to show this So this is whipper snapper update. Do check out a to fruit i o we do pride ourselves on having like the The less friction as possible. We're making I know we're making it too easy to do iot projects, but that's okay Um, do do check it out. Um, there's always a free way to use our stuff No, you don't even have to type in a credit card number. Yeah, you can just get started We have to buy nothing you can just we do require an account because you have to make sure that you know Nobody else uses your data. Yeah, of course, but uh, it's instant free and we don't sign you up for an easel And the way we handle paying are like, why are you doing this because we sell hardware? And we figured instead of having an iot service that eventually goes out of business and you rely on and you're like, oh, man Uh, we thought well, we can fund it with the hardware we sell There's carcasses and iot services is sad broken iot services out there toys that are broken That um got discarded. So we said well, well, can you do to avoid that? So we sell hardware Okay, let's do some Python or hardware Okay, this week. Um, first up, we're gonna just talk about some circuit python nine Updates and more. This is in our newsletter. You can get it on adafruitdaily.com You do not need to even sign up and get an rssv You can Um, you know do any tracking we make it so, uh, it's a completely separate website than even our store adafruit daily dot com. So what's the latest and greatest lady data for circuit python nine that you want to mention? Well, the stuff in nine That's really cool is um stuff that i requested. So Um, first off, we got more usb host support usb host is is nice because Um, it allows you to plug in keyboards and mice and disc drives and you know, you can use them from within circuit python I know that scott's also been working a lot on Wi-Fi web workflow. Um, I don't know if that's Shown in here. There's new um a lot of dynamic heap allocation stuff that's changed It's internals, but it means that we can do usb host because we can allocate memory a lot easier Jebler has been working on jpeg decoding support natively so you can draw Jpegs using display io, which is great because for the larger qualia screens The screens are so big that the bitmap files are just like Junky they take up like all the disk space. And so we need to have compressed files. Um and jpegs are Very easy to decompress and well supported standards. So we're gonna do that a couple other details there like little synthio mdns i2s Um updates, but those are the things that i'm kind of most excited about yeah, and then thing. Um, this is kind of like bonus edition so in addition to all of the um projects and more um, we'll cover this um This book in our We do, you know extend out so all flavors of python and also scripting languages on microcontrollers and raspberry pi Which has a ton of python stuff going on of course because it's a linux computer And just regular old python resources. So if you're interested in one of the more popular Programming languages and all the things you can do with it. Do check it out We like to keep track of the things that people are building with open source hardware Um, we like it of course when there are things that people can learn from and we like building some of those things So, um, we have some good news our camera The open source python powered camera. This isn't a python nine. This is a nine. That's another thing that nine added to support Yeah, so we're starting python nine You can use a camera. Um, this is our 3d rendering and it's beautiful. Um One of the things that we do is there's lots of ways to say you're open source a lot of ways to use the word open, but It's uh It's here. So I type camera. There's camera. There's camera like sensors But we think this is one of the only Opens complete cameras that you can take a photo with. Yeah, um, so it is now open hardware certified certification date December 19th Yeah, uh, right now we are I'm gonna type ate a fruit. I think we are up to 700 something 723 projects Um, so yeah, can you click on certification date to sort of origin date? Yeah, because then we sort by like the latest there again. Yeah Yeah, so the latest board's around. Yeah, so the host feather wing So we're keeping up with our latest design. So it's a 723 um, and if you look at the total number It's 2616. So we're pretty proud of the fact that we've been able to keep up with Uh, doing these certifications because it's important to us for you to have the files The source code and all these things and this is you could say it But this is this is just one of the ways that you can send the signal that this is really important so thanks to um, folks at ashua who maintain this and uh, thanks for the community that encourages us to do open source hardware I like that. There's like that. It's not just us. There's a canada in germany in spain. That's kind of nice Yep. Okay. Let's uh remind folks It shows up every week Needed for tally. That's pretty good newsletter. Okay. Speaking of open source hardware lady, we Have a bunch of guides that we do every single week.  Okay. So we've got a guide for the usb host feather wing Let's go up this up. This is using tmsb. So tack Added support in tmsb or our open source usb host and peripheral stack that like almost every chip company is using now So, you know, we played the long game I think tax started this 10 years ago before he's joined ate a fruit and then he's working been working with ate a fruit and he we You know sponsor him to do tmsb support Um, and so he added support natively for the max 34 21 as like an underlying transport So you can now use the tmsb host examples, which are like really great and like like hubs are supported and mass storage and cdc like an ftdi chips and Keyboards and mice and midi and all that good stuff If it's supported by tmsb, you can now use the max 34 21 e which is an old school but still great usb chip It's now we have examples published documented on how to use it with the usb host feather wing jp and lis collaborated on this cool project. This is a mix tallow project or i don't know if that's it midzela um project they made they made a um reverse oscilloscope synthesizer and i was like that's such a good idea and we had this eight channel adc board that we just released and so i was like take two of them and put 16 fader potentiometers and then you can draw waveforms And synthio will create that waveform and i'll put it Out of like the deck or out of the i2s or out of the pwm output um And so this actually is like a little synthesizer you can draw the waveform but you can also pipe it into your Modular synth i just thought it'd be fun. It's like it's fun to draw square waves or triangle waves And then you can instantly um hear what it sounds like so i thought that's kind of neat And then there's like a little ui up there to to change the frequency and kind and stuff Uh erin did a project. It's an easy show the video mechanically easy But electronically very complicated. It has two w led boards With the esp 32 qt pi and they synchronize together So you have two shoes, but they're like they're going to run the same animation Using w led so you like load them with what you want to do and then they'll synchronize with each other So I thought that was a good project um to show off some advanced w led usage and of course Our fun uh flexible neopixels on a rope And then none Pedro kind of you know, they built that project with the fireplace the tft fireplace And I was like, oh, let's make a round ornament one and they're like cool Like good easy project to finish up the year Um, so that's a barbie themed uh pink tree and it's got a video playing ornament with an esp 32 s3 qualia board So a great way to wrap up the year some good some good projects Yeah, so we're gonna play the video by erin i'm gonna do some factory footage and then we'll go right into some 3d so here we go buckle up Light up the dance floor with neopixel shoelaces that pulse animate and glow This is an easy beginner project with a little soldering a little crafting and no coding at all Customize colors and modes using the free w led software and control your shoes right from your smartphone W led's access point mode makes it easy to sync the lights in your shoes or other costume pieces together Even when you're not in wi-fi range These shoes will be perfectly in sync no matter where in the world you take them See the full build tutorial at learn dot adafruit.com and as always remember to subscribe for more fun costume building ideas Thanks for watching and here's some factory footage That's some factory footage 3d printing. Okay, we're gonna do these videos back to back It is the round ornament and then a speed up take it away No, wait and Pedro You can build a festive ornament that plays clips from your favorite holiday movies using a round tfp display in adafruit's qualia esp 32 s3 This project uses a round 2.1 inch capacitive touchscreen with 480 by 480 pixels to play video clips stored on a micro sd card The video loops indefinitely and you can tap anywhere on the display to play the next video making this one of the most unique ornaments Powered by the adafruit qualia esp 32 s3 This dev board is designed to work with rgb ttl displays in peculiar shapes and sizes The electronics are housed in a compact enclosure that can hang on your tree with access to the sd card slot Installing software on the qualia board is as easy as dragging and dropping the ready to go uf2 file Thanks to the tiny usb bootloader You can use the convertio website to encode your favorite videos to the mjpeg format and resize them for the 480 by 480 round display Then just save your encoded videos to your micro sd card for a full tutorial and files head over to learn adafruit.com You can get the parts to build this project links are in the description 3d print the parts in your favorite pla filament or have a 3d printing service print them for you Plug and play jst cables make it easy to connect the micro sd card breakout to the qualia esp 32 s3 The round display is secured to the enclosure and held in place with a snap fit insert The sd card breakout and qualia board are secured to the built-in standoffs with machine screws The components are cleverly positioned with proper clearances to connect the display the back cover snap fits making it easy to open back up if you ever need to Use the ornament's built-in loop to hang on your tree and you can power it with either a usb power supply or a usb battery bank We hope this inspires you to check out the qualia esp 32 s3 for your next video based projects The code is PADC 10% off an adafruit store You can get all these free things on your way out The only thing that's not included is gift certificates But this is a little bit of a reminder if you're looking to purchase something for a gift for someone who likes to do electronics You can do that now too. Just know that discounts, of course do not Apply to gift certificates. Let's do some mine up. Yeah, lady Hi Hi on imp. I brought you by did you key this week? It is analog devices Lady data. What is an imp? New product introduction of the week. I'm glad you're asked This week's imp is going to go long. It is the ltc 4332 Linear tech which was purchased by analog devices. It's analog devices, but sorts of the ltc But still, you know the quality and reliability of linear tech. They make luxurious electronic components Now available at m long devices pricing and distribution And this one is long because it is a long distance spi encoder extender Which is and I always love to put cats in these photos. So here's a long cat. So this device It's a spi extender and we stock a similar chip the ltc 4311 which is an i-squared c Bus it's not like an extender. It's like an active terminator But it's kind of the same family of like usually i-squared c and spi are protocols that you use on a pcb They're meant for short distances of like 10 centimeters at the most They're meant to go fast. They're meant to um, you know, just connect from one component to the other Maybe you'd have a short cable, but they're not meant for long distances But sometimes you need to have long distances. So what's cool about the ltc 4332 is it's like a transparent differential spi Port expander, sorry extender. They can go up to 1200 meters which is 12 football fields. I still love using football fields to measure. So very very long cabling You're not going to get the full 2 megahertz max speed over it We got like 50 kilohertz or something, but still uh, it's pretty amazing to be able to do spi. We're such a long distance so The way this works is you need two chips one is the controller and one is the peripheral And on the left hand side, you see the controller You get the sck miso mercy pins. That's like the data in out and clock there are four Purple select pins ss one through ss four not that ss four is for the chip itself So actually you only get like three chip select pins, which means on the other side You could have up to three spi devices that you can address so it's like you Would have it on the other side and then you know, you would have like a display and then maybe you know sd card and then maybe You know a thermocouple all on spi they can share those pins and they each have their own chip select pin um And then in between and there's also an interrupt back so you get on one interrupt line go backwards To like alert you when like data is ready and stuff And in between you have cat five cat six cabling So twisted pair is differential and the chips and code the spi commands Over the differential pair for tx and rx and so you can use like your standard Long ethernet cords which are low cost and reliable And then a link light lets you know that they're connected. So, you know, really easy to use Um, what's nice about this a couple like little details that I saw that I thought were really well designed one I like that. It's like transparent right you you just you connect it up and The controller and the peripheral have no idea that it's going through this long differential link That's handled for you. It can do all four spi modes because I know that there's some sensors and devices That use, you know, most things use uh mode zero But some use mode three or mode two or mode one And it can switch between the two so it it will dynamically Do the right thing even if you have multiple different states Sorry different modes of sck you know polarity and and Latching as long as the chip select line is active low, um, it'll automatically do the right thing for all your different peripherals on the opposite side Um In the middle is this differential, you know protocol. It's not published. It's like, you know, some whatever proprietary protocol and um You connect one to the other so you can't have multiple Like peripherals on this side like it is one to one Um, they have some, you know limitations on how much your grounds can flow That I think has to be within 25 volts You do have to select the speed. Um, and I think I'll show that later But the speed tells it how much to overclock the differential link Which will determine your max bandwidth, which is like your max, you know max bandwidth S clock speed versus the distance. So it's like a tradeoff of How far you can go versus how fast you can go you can't go the Higher speed at the longest distance. It's inversely inversely correlated Um Okay, so this is the inside of it. There's the encoder decoder the link um, the spi pins The fifa's which we'll talk about the fifa's actually um matter when you're doing receiving Um, the link light and there is the device itself is also an spi peripheral Which you can configure when registers although you don't have to So the link light I thought was kind of like a nice detail So just like ethernet when you plug it in and it detects that the other side is connected Um, and led will go on um, and it will also like make sure that you You know matches the right speed you also query it over spi if you don't want to like use the led um The link speed like I mentioned you can use two pins or you can set it with uh with the spi registers so There's eight levels and each one you can see Second to last column it goes from two megahertz down to 25 kilohertz And that will change the max length of cable from 100 feet to 1200 meters or more So It's one of those things where you know, it does depend on your cabling your power supply You know, is it outside? What is the noise like in the area?  Maybe it says use speed index five, but maybe it's speed index four So you have a little bit of leeway um, and of course You'll want to go as slow as the slowest Device like each device has to share the same sck So if you have a device that this can't be clocked faster than 100 kilohertz, you're going to have to set the entire bus to 100 kilohertz Okay Next up. Oh, there. So there is registers. It doesn't seem like you need to use these a lot of it is just like reporting on faults failures You can't change the speed index overflow underflow and word length and the word length has to do with Um, the latency So there's only one thing you just have to watch out for that might affect your firmware programming So if you're only writing from the controller to the peripheral the data is is Transmits, you know transparently, but if you're reading data in because it has to read the byte and then transmit it out because like, you know If you use spi, usually you clock things out, but then you could also clock things in on the same Um clock in and you'd have it be Both mosi and miso active on the same sck signal Obviously it has to get a byte at a time And so it's going to be one byte behind when it reads data data written is going to be Done on the clock because it can like send that byte at once But as it reads it in It's going to be delayed. So your firmware might have to If it's reading from the spi interface, it'll have to drop the first byte And then from that on it'll be synchronized. So, you know, just something to watch out for Um, if you are reading data, there's a lot of sensors that don't but if you do You do you might have to change your firmware a little bit just to like be aware that The first byte gets dropped And then you can get an eval board. I like this one because it's like breakable You can see in the middle that you break apart and wire up Cat 6 cable and you don't even need like an ethernet connector and then in between I think it's like a p-mod port so you can just like connect it to your ready to go p-mod devices And the chip is in stock So if you want to purchase it, yeah, you can get it. Um, don't forget you'll need two one for the transmitter And one for the receiver, but then I'm going to make a breakout board for this chip. I really like it I like the um, ltc 4311 for iSquirtzy. It's been a great expander. It lets you take iSquirtzy up to, you know, 100 feet easily Ethernet but this one because it goes over a differential link. It's going to be again 1200 meters or more Yeah, one of the cool things about this npi series is new product introduction Often or sometimes or at least now that there's stuff when you see it here that might mean more work on a breakout So it's a little bit coming to the new product for this week the mcp of 3421 was Two weeks ago's iNPI.  It's and I liked it so much I made a breakout board for it. All right. That's how, you know, I got a seal of approval That's this week's iNPI All right, we're gonna roll right into new products after we remind you the code Patsy P. A. D. C. Um, let's do it, right? It's a raspberry pi Yes Cases they're in and they're gothy. Okay. Yeah, we know the photo was the white and red one But you knew we weren't gonna stock that black and clear one because of course, okay, of course, of course Perfectly raspberry pi five will not fit any other raspberry pi only the pi five Um as a built-in fan using the new fan connector. Uh, that's fancy. It's got a little heat sink element of a passive one Um, I think if you pop out the fan, maybe you can use the active cooler, but it's a nice snap together case Uh, it looks cool. Looks god as a little rubber feet as well.  So you know Yeah, we'll like we can't guarantee we'll have both the pi fives in the case at the same time. So I don't know That's how it is. No one can guarantee that nobody can guarantee I do like the way we handle the pi five sales because folks have told us that they have back orders pre orders From september from other places. They still haven't gotten yet, but they did get the ones they order from us. So That's why we did it. Next up Next up a new edition of programming the pico from simon monk second edition now covers the pico w Which is great. Uh, simon monk is a wonderful educator and writer has written guides for us, uh, has published uh multiple parts of the learning system Um, and we have lots of his kits and books you can see some fantastic Pages we have a couple previews of the book. You can also Get it just about anywhere. We stock these types of because often Um, folks are like, well, I don't really want to buy stuff from amazon But I do want this bug maybe for maybe you'll stop the authors. Yeah That's how you get more books written. Okay, and next up next up. It's coming soon But uh, I'll probably be in stock for next week But I thought a bunch of people might want to sign up for it It's a grow feather wing So if you have a feather and you want to use grow sensors From seed or other companies make sensors that are compatible This board is very compact, but it has three analog grove connectors One u r and two i squared c Plus a stem IQ t that's like, you know for the fourth day of christmas My journey to me A board with a stem IQ t and a louisa button. Um, so it's it's simple inexpensive but Makes it mechanically easy to plug and play existing grove sensors that you may have Okay It's coming soon and the stars shirts and I besides you lead it our team our customers our community and everyone Who's making this thing go? All this year is The mcp 3421 18-bit Analog digital converter with i squared c this little chip from microchip is it's a nice High precision analog digital converter and I'm showing here and you know, what is this? What are you seeing here? So this is a k-type thermo couple wired directly up to the abc. There's no op amp in bit in in the middle. There's no Special chip It's just the analog digital converter reading 18 bit with the programmable gain has a built-in pga I think of eight eight ton gain and it can read a thermo couple and actually like Get you know, you can measure temperature From it. I didn't do the temperature conversion.  So it's like 10 uh, you know every Least significant bit is one tenth of a degree Um, it's fairly fast. You get like three or four samples per second when you're dealing with 18 bit sample rate. Like I said, it has built-in gain It's i squared c so it's like easy to use with you know, almost any microcontroller or microcomputer Um, it's got the terminal block built in already. So you can just wire something up There's only one i squared c address. Um, but you know, that's okay. You could always uh Use it with a gpa of expander. It's not that fast anyways where it's it's four samples per second at the most precise readings Um, it's good from 3.3 or five volts the inside. It's got a built-in 2.048 volt 1% Voltage reference so it's a very precise voltage reference So the signal that you get can be differential But just note that both sides of the differential signal have to be less than two volts So it's really good for like wheat stone bridges and thermocouples and strain gauges Stuff like that. Um, not good for a potentiometer where you want a full like zero to vcc or zero to 3.3 volt Input this is for a precision reading of differential signals. That's where it's going to shine And with that is new products No, no, no, no, no Okay, so, um, don't forget to code new all the rest of no, no, no, no if you miss out No, no, no, no gives give certificates some of you will be getting an aida box email tomorrow And continue to be shipping as the new year kicks off. Thank you for sticking with this um, we're gonna do some questions, but first, um You know, make sure you're in discord a different dot at slash discord or discord dot gg slash Eight if we're gonna do some top secret then we're gonna do the questions and then we are going to bounce you ready bounce Okay Super top secret what you're working on. Okay, so the The march of revisions continues. It's not march, but I would like to finish. We'll look for march up to the 571st revision getting to the tougher ones now. So this clue, uh, board revision Um, love the clue board every single chip on here was unavailable for a year and a half Yeah, let's do the chips of theses like there's boards that we have that everything's different, but it is the same board Yeah, um, so this one, you know, I couldn't get the nr 52 a 40 and then I couldn't get the the microphone and I couldn't get the Magnetometer and then the six doff got discontinued six doff really did get discontinued so that got swapped out I couldn't get the magnetometer. I was about to redesign but the mag tomber came back at the stock at a reasonable price and then Whatever, whatever, you know, eventually I was like, okay, I can I could actually get this back in the stock So this just revises the lsm 6 ds 33 is now just an lsm 6 ds 3 which is basically almost the same chip. Um, so a different package But um, all the other components were available even the bmp 280 which was unavailable for like a year. Um is available Again, the old price, which is another thing. It's like for the this clue board for me to be able to sell at the price I can't be spending five dollars on a magnetometer and the pricing was Really ridiculous for a bit. Um, but all the prices came down again And so this is being revised all the parts are being updated the most recent versions I'll get it back in the store Um, ditto with the feather sense. I know people really like the feather sense board and believe me I wanted to stock it for a while, but likewise Almost every sensor got discontinued actually another thing is the apds 9 6 6 0 that got discontinued too But we did a last time buy I think we have enough for a couple years So I think it's worth it. You know instead of doing a wee wee redesign I guess I'm gonna get a good enough to put it back in the shop Buy me a year and then in a year when I when more parts are like really discontinued cleared out Think a lot of things that were unavailable were being held by companies I don't use the word hoarded but like kind of sort of And they stock out and be released to like, you know, whereas at before I was like I couldn't get any chips Suddenly there's like a hundred thousand of them in stock. Uh, so, you know, it's working out Yeah, what's funny is when I tell people that aren't in our industry about this they're like, oh, yeah, like I need it apart from my car and they said it's going to be four years Like it was like it it impacted everyone in so many weird ways, but it is over now for the most part It's allowing us to do a lot of stuff. That's top secret. You'll see more In upcoming episodes I'm asking engineer. Okay. We're going to do the questions. Let's do it. Yeah We're great. We're doing good. Yeah, we are Um, let's uh get the ones that we haven't locked up Okay, so first question was, um, where should I go to learn about making PCBs? I want to make an LED badge in the shape of a I think T plus yeah, I don't know where to start. We have a guide actually making LED badges We have a guide on making LED badges all learn data for definitely Yeah, and what a good I'm doing custom silkscreen just for your first batch check it out The other thing you can do is um look at some of our open source hardware designs And you can you know just move stuff around. Yeah, that's a good way to learn. Okay. Um, will there be a memento enclosure? There is a memento if you can sign up where I have to get the m3 screws Um, but they're coming in hopefully soon. So they should be in stock by the end of the year Okay, and I think this question was in reference to the ion mpi that we're doing Uh, why not just use ethernet instead of the ltc4332? It's a good question in the text for the uh, ion mpi, I talk about that. You may not want to have Um, a full ethernet controller Um, if the thing on the other side really is just like spi and you just need a sensor node And you don't want the weight of like a tcpip connection And you know the power required for that. This is going to be Um a lot simpler. Um, it said like you know used for lighting I could see why you would want to skip having the weight of a full ethernet driver Um, and instead just use this you know one to one tap connection Okay, do you think the mcp 3421 will work with the zirconia sensor? I don't know what a zirconia sensor is but anything that gives you a differential It senses zirconias Well, yes, um, thank you If it gives you a differential voltage of you know a couple microvolts up to two volts max Or if it's a resistor and you can put it in a wheatstone bridge, then it'll work fine Okay, um, this I don't know what this is But maybe you do what protocol to use between 10 centimeter and 5 millimeters are s485 and this new thing really practical or 10 meters Um Will I to see cleaner terminator thing for due to meters the the terminator the ltc 4 3 1 1 the i-squared c terminator will go up to 100 feet. Um, so it's definitely good, you know 100 kilohertz For 5 meters 10 centimeters 5 meters that is tough, right? It's like what do you do like r45? Yeah, it'll do it I squirts you'll do it with an extender Um, it is a tough distance, right because it's just like a little bit too far Um, but I think I think you could do i-squared c with the terminator You know, if you're if you're if you're okay with that and you don't need a lot of power Um, I think that would do a fine job. Um, does the month's book cover ble programming? I don't know you might want to look on the um the publisher page for the table of contents There's a couple contents. I I imagine it does an example for wi-fi example. Yeah, I don't know 100% I don't have it in front of me Um, so check out the publisher page if I can get to before the next show I will too Yeah, um, does the flirt case for raspberry pi 5 work with the active cooler or is the whole thing being a heat sink? Um, you would remove the top and then you would put the active cooler on top So you wouldn't be able to use the top at the same time because that that passive heatsink would get in the way of the active cooler Um, so that's the trade-off with the active coolers. You can't have anything else on top Okay, and let's see do do do check it all the chance. I think we Got to him. Okay We got to all the questions. Okay, perfect timing Good timing because we need to get here right at nine tonight. Okay practice my singing. Yeah. Thank you everybody for making this a fantastic year as we've crawled scraped slid across the finish line of 2023. Um, it was a um Busy year for us. We needed to redo Redesign recalibrate optimize adapt. We also had a kid So we were dealing with that and we also wanted to take good care of our team Of our customers our community. We wanted to hold tight to all the values that you all expect from us So it's been a roller coaster a year. We very much appreciate you sticking by us. You got choices where you buy stuff Um, we're going to continue to do open source hardware. We're going to continue to get data boxes out Um We're making so many neat things. Um, I can't wait to show you. Um We're we've got so many neat things That we're finally able to get out the door. So, um, this week is just wrapping up some things for the year Um, given our folks time off and everything they're taking time off And uh, we're getting some data boxes out. I'll be emailing people tomorrow morning I know and you'll be getting an email Some of the ad box customers like you ate them today. Yeah, and uh, we'll um resume right after the holiday break And we'll see everybody in 2024. So thank you so much. This has been an eight fruit production Here is your eye Here is your moment of zener Good night everybody. Bye. Bye


Johnny dollar. All right, Johnny. This is Bob Baker. It's surely mutual insurance limited over there in Daryl Boston, man Yeah, that's right. How are you big? It's been a long time. Yeah, I know what's on your mind And I hope it's something that'll earn me a nice fat commission Well, the matter of fact is a chance you just might clean up on this one Oh, you ever hear of the Ivy Emerald? Nope. Well, you should have happens to be one of the biggest chunks of that green stuff It was ever polished and put in a setting bake the only green stuff. I'm interested Yeah, I know. I know the folding kind. That's right Now tell me what's happened to this Ivy Emerald? What's your guess and listen Johnny?  I hope how much the insurance on it. I mean $625,000 Wahoo. Yeah You want to come over here and talk about it? I'm on the way CBS radio network brings you Mandel Kramer in the exciting adventures of the man with the action-packed expense account America's fabulous freelance insurance investigator yours truly Johnny dollar Submitted by special investigator Johnny dollar to surety mutual insurance limited Boston office Following is an account of expenses incurred during my investigation of the Ivy Emerald matter Expense account item one is six dollars cab fare to Bradley Field Item two ten ninety planes After landing at Logan international item three is two and a quarter for a taxi into Bob Baker's office on Boylston Street Sit down Johnny. I'll tell you what I know. Okay, babe. Go ahead. Well first of all I'm surprised you weren't familiar with that Ivy Emerald is all over the magazine picture magazine a couple years ago Some big Middle Eastern potent they try to pry it loose from our client. What's the name of the client back? Mrs. Oscar B sterling wait Emily sterling wait a rich old widow lady Mm-hmm, and why the name Ivy Emerald because of the mounting it's a brooch of solid gold in the shape of Well, Boston Ivy. I see old Emily has a collection mostly of diamonds worth literally big Only the emerald was taken however taken from where bank our wall safe in her home Well, she put it last night after wearing it to some charity ball Was it a nitro job? No It was opened in the usual proper fashion by means of a dial and her diamond collection was also in that thing No, only paste copies of some of the diamond stuff for casual wear Ordinarily she keeps her important jewelry in a bank vault but having worn this piece the night before See in other words whoever took it either knew beforehand the diamonds were only paced or Simply recognized them as such and that's the reason you didn't bother with them, right? Well, the chances are then he's an expert, right? Who else knows the combination of a safe? Well, she's the only one you sure that she swears to it If she were to die without telling it to somebody else the only way to get in would be to blast apparently somebody has So she isn't the only one who knows the combination. Oh Yeah, see what you mean She's absolutely certain. She's never told it to anyone a good set the scope will pick up the sound of the tumblers dropping big This box has an oil dampen movement the quietest type. There is made especially for by the Darlington safe company right here in Boston Darlington, well, maybe that's the answer. Oh, how do you mean? Let me have her address. Would you bake? Oh, sure? But what did you mean about maybe that's the answer? Do you know man Darlington? No, never heard of him before or his company. Well, I do know him And if you think that Darlington who personally codes all the boxes they put out would be the only one with access to the records of the Combinations that he sold if you think that he could take my boy. Let's wait and see Item four is the usual 50 buck deposit on a rental car And a few minutes later I was in the Beacon Hill section of town a block or so north of Commonwealth Avenue Mrs. Emily Sterling was one of the fine old beautifully kept mansions that dot that exclusive expensive residential area The front door was open for me by a uniformed butler Since a barbed phone to her that I'd be along she was waiting for me in the mahogany panel of library Because it's in here that I have the wall safe mr. Dollar cleverly hidden behind a movable panel May I see it mr. Sterling with? Of course you may It's right over here Do you see I pressed against the molding here and here and the panel slides away and Here is the safe. Oh That is well hidden mr. Darlington himself to provide the installation of it a long time ago When he and I were quite young and he was up was calling on me. Oh But then of course I married Oscar. I see yes, Harry Darlington dear dear boy was one of my most faithful admirers Now the size of the dial here on the safe. Well, that's because of my eyes You are very attractive eyes, mr. Sterling. Well, thank you mr. Dollar. You're very sweet They've always been one of my better points even as a young girl The only problem is I don't see very well I never have and that's so well. That's why Harry bless his understanding heart made the dial so large for me I don't usually tell that to people though. I'll never mention it to us. Oh, thank you now Who else knows about the safe in here since Oscar died no one but myself and of course Hendricks Hendricks the butler The butler but good heavens mr. Dollar you couldn't suspect him good night Well, you saw here. Yes, and I must admit that he doesn't look the type What's more he's been with me ever since I was a well for nearly 40 years Does he know the combination of it? No, no one does but me. Well, it's somehow somebody Mrs. Telling when he has any servants left you recently Oh when oh about him off the go that was Honored a bit. I believe why well this may be shooting in the dark, but do you by any chance have a picture of him? Well, yes, I guess I do have the one that little Evelyn my niece took with the camera. I gave up for Christmas Should be right here in Here it is good. Yeah, mr. Dollar Evelyn was quite taken with him and he was such a very nice young Oh Oh What is it? Wonder yes, I Don't recall that name on the big speed course. It may have been a funny But I'm sure I've run across this man somewhere in the course of one of my investigations Oh, no, really, but it was so nice and mr. Dollar. Yes, how could he possibly have learned the combination of the safe? Would you like me to show you mr. Stirling went? Would you like me to open it for you? You think you can I think I can but how? Harry Darlington absolutely guaranteed that no safe cracker could do it by listening to the combination or anything like that No doubt he did mr. Stirling wait now look, I'm going to leave the room While I'm out with those big double doors closed behind me you open the safe Would you do that, please very well if you like all right then I'll leave you alone But if the combination can't be heard even with delicate instrument as soon as I've closed this door You go ahead Now I waited outside the door then for perhaps a minute, maybe less than a minute then Mr. Dollar good. I said good now close it again and give the dial a couple of extra spins Very well lots again. Oh, I'm sure of it Let's see now the 36 How did you know? Oh, this is a quiet one now three now one full-turn past 14 to Yes, this oversized dial and the big numbers on it Even so there's a crack between those doors nearly a quarter of an inch wide and you stood away from this Mrs. Stirling wait a full arms length because of my poor eyesight I could have seen how you turn this dial from really twice that distance. I see So that show for or anybody else in this house could have learned the combination just as easily as I did Arnold Bixby you said yes, but now he's gone and I don't know where and if he is the one mr. Dollar That's only a guess but it happened last night And if he was smart enough to have done what you did with all the airplanes and things these days Oh dear he could be far far away or if he's real smart He'll stick around long enough to have the emerald taken out of its mounting and broken up that beautiful stone Carefully done by an expert who would only do enough to destroy its identity without fracturing the main body of the You have notified the police, haven't you yes, there's a fine handsome young sergeant will it be in charge good and the first thing for me to do it? No No, maybe I have a better idea. Let's see now three possibilities so far as always in the case of this kind Mrs. Stirling wait herself Of course, there was nothing to indicate that she was the type to use a trick like that Second course was the ex chauffeur whose picture was familiar to me, but only vaguely so and from where? He might have to find out more about and finally there was Darlington But then in the office of his little safe company when I met Mrs. Stirling wait dear dear Harry Darlington Well, I'm afraid any suspicion of him promptly vanished into thin air. He is honest distress couldn't possibly have been faked Oh just just terrible mr. Dahlin's just terrible She always loved her jewel so much, you know and especially the emerald And to think that one of my own safes made with such loving care betrayed her Betrayed her trust in me in spite of my devotion to her over all these years. Oh Dear, I I fear that I shall never be able to face up to her again I've let her down. She'll never forgive me now Mr. Darlington from From what she told me about you and and her feelings about you. I Think she would like nothing better than to have you right there to comfort her You really think so mr. Dahlin? You think she'd be willing to see me again after After this I do indeed Why don't you call her up and see? Yes Yes, I shall but first if I can be of some small comfort to Emily but first mr. Darlington I I want you to take a good look at this picture Yes Picture of this chauffeur she had This man Emily chauffeur You know him he was employed here in my plant for a while almost a year ago His name was Roger Goh Roger Goh hmm Then it would appear that Arnold Bixby was merely an 80s. What's it? No, nothing. I'm sorry. Go on. Well, he was only a truck driver and a loader, but I Well, I just didn't like him. I'm a splendid judge of character. Oh, I'm sure you are Yes, and when I found him here in my private office one day when I'd stepped out for a minute Wait just one moment That's safe There in the corner. Yes, sir. Is that by any chance where you keep a record a Record of combinations of other safe that you have built over the years. Yeah Yes, yes, it is. Well, then that's where he got it But he could only have been in here a minute or so for a man who knew what he was after that could have been long enough Thank You mr. Darlington Thank you very much, but we did yes This safe was locked when he was in here you sure of that I'm quite sure only quite sure So maybe that's the way he found out Maybe it was the same way. I did At any rate, I think he's our man. Well now mr. Darling. I'll see you later as for what happened next The way things just kind of fell into place Well, you can call it coincidence if you like, but it wasn't no it was simply a matter of knowing which way to turn In this case it was to an old friend an ex-convict an ex-cruc who knows more about the ways the methods the denizens of the underworld and Anybody I've ever run across simply because he was a part of that underworld at one time Item 5 10 cents for a phone call to smoky Sullivan smoky. Yeah, this is Johnny Dower. Oh Johnny How are you Johnny? I'm fine smoky. Just fine. Tell me you Still an undercover man for the Boston Fire Department Yeah You know something Johnny what? Since they've been letting me help them out They got practically no more set fires around here. Oh good boy Listen smoky. Oh, Johnny You're less. Hmm. I've been trying to get you on the phone all day. I've been trying. Oh, well, I'm right here in Boston The main on a kind of the emerald. Yes The IV emerald. Yeah, well, that's why I've been trying to quiet. Oh, great smoky. I knew this hunter mine would pay off Yeah, I know that gets you in on it and it kind of the insurance. You know where it is But you know who took it no No Well Well, then what about it smoky? Maybe I got a good way for it sit tight smoky. I'll be right over Time is late at night when business gets slack here in the diner and I'm listening to the radio. I think to myself I mean Suppose that new for a day walking right now sit down at the counter and say I mean from now on I want you to smoke new ports filter cigarettes You know, they have to suit in coolness a mental a hint of mint and wonderful rich tobacco It's that exclusive pleasant smoking combination that makes new for more refreshing to begin with more refreshing all the way Will you do this for me? I mean? Maybe I'd say take the place. Oh joy the steam table the coffee maker. It's all yours I'm a new port smoker forever You think you have a lead on the IV emerald. Yeah, well Johnny about five blocks from here As a man lives that used to be a fence back in Chicago, huh? Yeah, his name is build though Fritz build though. He handled hot jewelry. Yeah, and he was also a diamond cutter also a gem get him Yeah, and he has he been fencing stuff around here.  Yeah, no Wait a minute.  Breed don't you know The man he's the best jewel heist this size of state crime Then it's no wonder he'd go for the IV emerald Of course it all ties up his job with a safe company under one name is acting a chauffeur to mr. Sterling Wade under another and With this bill though here to break it up for him. Sure. I think money took a giant. Well, don't you smokey? Where is he? I didn't even know he was here. All right, then our job is to find him Tell me what do you know about this gem cutter this bill though? Oh What do you say? It was an account of the pilot trash around build those place that I started watching them pilot trash Yeah, the way I seen it piled up before when somebody's may be figurant as Have an accidental fire to collect the insurance. Oh, yeah, go on. Well, I know when I found out who it was Bill though. Yes, go on. So last night. I phone my contact on the arson squad That's Tommy Winkler. Oh, sure. I know lieutenant Winkler. I've been knowing very well. Go ahead smokey I told Tommy Winkler to better check up on both. All right. So you told lieutenant Winkler. What about the emerald? Oh, yeah, yeah About 3 a.m. This morning. I took another look at those plates and the car. We had a light on And there he was in his shop at the back Yeah, but when he see me looking in the window he kind of quick show something in a corner Quick turns off the light smokey and he and he pulls down the shade so I and nobody else could see it Okay, what did you see was at the emerald? No, Johnny Well, what was it then?  Let's go. Yeah It was after dark now the place will build a lived was a little more than a dark alley The shade on the back room that he used for a shop was totally drawn But there was a light inside Maybe manny is in there with them. I don't know smokey. No, we'll take no chances When I kick the door open What and I'll reach running gun because I got this Man he prays that's right. Or is it Arnold Dixby or maybe Roger Gold?  It's me manny What's this? All right, come on get inside book What is this see pal you were right about it being smoky solid in your song Yeah, yeah, and that's stone there on the work table many Well, what do you think this one? Who is he? Well pal? This is the great Johnny dollar Johnny dollar well, but he won't be for long Take his gun away. Yeah Yeah, let me have it now. You see dollar.  Shut it. Yeah. Yeah, I close it. All right. Nobody move. What's up? Tommy Tommy with watch him Tommy Like the US Marines Tommy. Thank you pleasure Johnny. Yes.
