Life in New York, it's Ask an Engineer. Hey, everybody, and welcome to Ask an Engineer. It's me, Lady Aida, the engineer, with me, Mr. Lady Aida on camera control and behind the scenes, chit chat and everything and dropping the discount code, which is usually that shortly. I should do that, I'll do that, too. We're broadcasting life from the if we had courses behind us, it's a real factory, so we do all of our kitting and shipping and the manufacturing and coding and videoing and more. Right now, everyone's home safe and sound and snug in their beds. Because we're done putting stuff together, which we were doing all day today and a lot of stuff went into stock today, too, which is exciting. But now it's time for Ask an Engineer, a one-hour-ish of news, videos, butt jokes and more. Mr. Lady Aida, what's on tonight's show? On tonight's show, the code is In-Wing because we have a revision of our product and if you want to save 10% off in the store, all the way up to 1.59 p.m. Eastern time tonight, use the code, In-Wing. Talk about some Adafruit live shows, including Show and Tell, which we just did a few moments ago. Time travel, look around in the world, make our attackers, our engineers, give you some news. What's happening in the world? We also have from the mail bag, we'll read some letters y'all sent to us. This week, no chip shortage, that's good news because we have the real world, our EEL, that is when we get stuff in stock, parts on a reel. We tell you what we got going on. Things are looking brighter. We're starting to get stuff in stock. I've wanted to go through a new job from jobs.adafruit.com. You can post your skills or if you're a company or entity that's looking higher. Awesome folks, post on jobs.adafruit.com, advanced manufacturing and some Made in New York City factory footage, some 3D printing. And then we have two, the segment's so nice, we're gonna do it twice. INMPI, we're gonna do two this week, Ublox and Scotch because last week we had so much stuff going on, could only do one, so this week we're gonna do two. New product. It's twice as nice. Top secret, we're gonna answer your questions and please go over to discordadafruit.it slash discord, that's where we do all of this, join 35,000 of us. We answer the questions towards the end of the show but you can ask questions throughout the show. Community and old shy men can hang out there 24 seven as well, all that and more on, you guessed it. Ask an engineer. Sweet. Okay, so paint some bills. Yes. Don't forget, in wings to code and when people buy stuff later, what do they get? Okay, so we've got still $99 or more a free perma-proto half-sized breadboard. We do not have the 149 freebie today, we actually ran out of KB2040, somebody bought a whole bunch of them. We're gonna be making more ASAP but $199 or more you get free UPS ground shipping in the Continental United States and $299 or more you get a free circuit playground, blue fruit, it's round, it's blue, it's got a Nordic chip, it's got buttons, it's got a buzzer, it's got NeoPixels, it's got alligator clips, it's the blue fruit. A great way to code Arduino or CircuitPython on the NR52840, a really powerful chip that has wireless capability. Okay, don't forget, especially if you want to buy a Raspberry Pi, make an account on adafruit.com, verify your email address and then set up two factor authentication, that's how we're doing it. We put some in today. We put some in today and there was an article I think on TechCrunch about the Raspberry Pi shortage except for adafruit, each week we are able to put some in and it's also managed to defeat some of the malicious folks out there that are buying Raspberry Pis and then selling them for hundreds of dollars. Not cool. Not cool, so this is managed to thwart them so we're gonna continue to do it. Also it's good internet hygiene and security. One little bit of shipping notice, shipping alert is on Monday, it's a holiday here at adafruit, indigenous people's day, Monday, October 10th. It's a float holiday for our team so we'll probably be shipping but there's also... Maybe some delay. Might be some delay. So on Monday, October 10th, indigenous people's days, it's a holiday for the entire adafruit team, ordered place after 11 a.m. Eastern time on Friday. Maybe delayed, please plan accordingly. Let's talk about our live shows, Lady Aida. Okay. By the way, we put all the holidays on our blog and social media and stuff. You can always check each week. We also have it on the outbound email when you... It's also Yom Kippur. Social Yom Kippur.  We just did show and tell. Be sure to watch all of them. We had some of our team shows, some of the projects we're gonna show tonight. Halloween theme. Halloween theme. But if you wanna see one of our products in action, DJ Divin3 showed off the Stemmahub with all of the backpacks going. Said it works great. Recent update from Melissa as well so do check that out. And don't forget, all this month, come by 7.30 p.m. Eastern time and you can show off your projects and of course Halloween costumes and more. Okay. Okay. Sunday as we do from the desk of Lady Aida, part one of this week's was... Well, I showed off a whole bunch of designs. I've just been on a tear doing a Stemmah QTF vacation. I revisited the Peacowbell, Peacowbells. I did a prototype one and then I kind of promptly left on my desk and forgot about it for two months. But with the Peacow W getting back into Circuit Python support, I was like, oh, I gotta revisit this board. So I made a little update to add a Stemmah QT port and then I showed a little IR breakout and also talked about the TPS 61040 which is a little 20 volt boost converter breakout that I'm designing. Then we do the great search. It's brought to you by DigiKey and Adafruit. This one, Lamar uses her powers of engineering to help you. Yes, you find something on digikey.com often. It's hard to find things because things are out of stock but what did you find this week for folks to help them out with? Yes, so we're still, you know, chip shortages is relaxing a little bit but we're still dealing with end of life stuff. A lot of parts, you know, they would be end of life and you'd have a couple of years to order them but the Fan 5331 which is like really a very popular in one of our favorite all in one boost converter chips. We use it for a lot of our OLEDs, backlight, biasing.  Okay, how am I gonna get 16 volts? This little boost converter would do the job greatly. Unfortunately it is now end of life. So we wanted to find a pin compatible Saat 23.5 boost converter with a built in switch that could take, you know, two and a half to five volts. So it's like, you know, three to five volts basically input and boosted up to about 20 volts. I don't need a lot of current because this is a biasing thing. So even 10, 20 milliamps is plenty just to, you know, activate the e-ank or OLED or whatever. And so we found a couple options. I don't remember exactly which one. TPS 61040 was out of stock and there was another part which if you watch the show, it'll tell you what the part was, that one with the name. Okay. And then JB's product pick of the week was this week. We're gonna do the highlight and then forget of course, JB show is tomorrow, but if you wanna check out the product pick of the week this week, here it is. It is the Halloween M0, spooky eyeball. One of the most versatile boards you can get even though it is super specifically a Halloween style board. And then go to the boot loader and you can drag and drop one of these UF2s. So let's try this dragon eye. So I'm just gonna click on that UF2 to download it. And then I'm just dragging and dropping it again. Sorry, you won't see this because I don't have my screen shared for that, but I'm just dragging spooky eye dragon.uf2. It's uploading it right now. And then it restarted. So now you can see we've got this nice spooky dragon eye. I can cover the light sensor to adjust the slitty pupil dilation there. So that is my product pick of the week this week. It is the Halloween M0, spooky. Okay, and then on Fridays at 5 p.m. we have deep dive with Tim. Tim Travel, I'm getting ready to do some news about Eight of Box. I'll tell you what I think we're gonna do. We have, we're finally at an if then statement, I guess I could say. So if we happen to get the 5,000 parts ish we need before the end of the month, we will do an Eight of Box if we can't, we're gonna send out an email because we don't like to spam people for no, hey, here's no information. We're gonna say, hey, Eight of Box resumes in 2023 because it doesn't make sense to try to ship something if we're not gonna have the parts by then. But it looks like we'll be able to do the Eight of Boxes next year, no problems. It's just nearly impossible to get 5,000 to something, get 100 or something. You can get 100 or something once in a while. Harder to get 5,000 or something. So that's probably what we're gonna do. We're gonna wait till the end of the month. And when we do, we'll put it on Eight of Box.com if we're shipping or not. All of our social media profiles, places, this show. And then we'll send out one email and it'll just be a one-time email like, hey, feel free to cancel if you want. We don't charge anyways until we ship. We do have a few thousand people waiting.  So if you wanna just like wait, you'll know before it ships. And then I think before the first one we do, if we have to do early 2023, we'll let everybody know ahead of time, hey, remember Eight of Box, ship shortage year? Well, we're about to resume shipping on that. Just have people have an idea that it's coming up. Let's do mailbag. All right, I put the wrong camera underneath the mailbag. Whatever. French fries. Yeah, there's some food. Sorry about that. I visit yourself a couple times a week to see the new products that have appeared. You offer new things so much faster than any other site. It's a blast. So it's certainly contributed to the sheer breadth of items you offer. Please keep going. Yeah. Next week I'll make sure I- Sorry about my snack making it appear. So because we don't have, yeah, because we don't have a chip shortage this week and we're starting to get stuff, we're now doing a new segment called the real world. This is the true story of nine strangers pick in place to live in a factory, to manufacture together, and have their lives taped. To find out what happens when people stop being polite and start getting real. Eight of Fruit, the real world. All right, we got something in stock, Lady. What did we get? We got chips, we got reels of chips. Okay, so we've got the MMA 8451. We ordered this from Digikey two years ago, almost to the day. And we've gotten some here and there, we were able to fulfill some backwards. We finally have enough to put in stock. So if you've been looking for the MMA 8451, it's an old, I think, NXP accelerometer. I know it's a 14 bit triple axis accelerometer. It was quite popular. We had thousands of people with back orders and signups, but we've almost gotten through all of them thanks to a big delivery of mini reels. And so, check it out. If you're looking for it, it's now available again. And there's a lot of them. It's been two years for a lot of folks, and I'm not gonna... Maybe not two years, sorry, it's one year, not two years, but it's still one year. But a lot of things we have are two years still. And so for... No, actually, no, it was two, I think the end of life was 2020. Sorry, what year is it? Hi, what's going on? So one of the things, I'm not in journalist mode, so I'm not really writing about this, hard to run the business and also write about this industry. So one of the things I'm not doing is writing about some of the things that's coming up. Also, I feel like there's confidential information, even though it's not confidential that I'm getting sent. It's like, oh hey, I'm at XY company, XYZ company, we're going out of business, or we have these parts, we're not gonna use them, or some pretty well-known electronic companies are just saying, hey, we're not, we don't wanna do this anymore, because it's been two years. Especially single-serving companies that have one particular... I was in two and a half years, and it's like, eventually you're like, I can't do this anymore, I can't wait around. You can outrun the bear for a while, except for eventually you can't. Eventually you get tired, the bear is not tired. Yeah. And for a lot of folks, it went from pandemic to inflation, to chip shortage to some workforce challenges, global issues from climate change with disruption in locations where there used to be a way to get stuff, and then there isn't, and then there's weather, and then there's, you name it, it's just been happening, and there's also some political issues around the world. So a lot of folks are like, you know what, we're outie. So we're starting to get stuff, but there is gonna probably be some disruption. So we're still doing everything possible to work around that. You're probably noticing we have more and more stuff in stock on a more regular basis. Then we have the BNL-055 still in stock right now, which is amazing. And one thing, after probably beginning of next year, I'll probably do a little bit of a recap of the things that we did. We're definitely trying to make it so it's not spiky anymore that we have consistent awareness of what's happening with the chips we're gonna get in, with the parts, our production ability, and just all the wacky things that happen. I think it'll be helpful to some businesses to see how we learned a lot of lessons because we assume if this happened now, it's gonna happen again.  There's that old meme. But hopefully, this will just make us smarter, stronger, better, faster, and have more diversity in our supply chain, and also be able to switch different chips out. So we'll see how it goes. And that's this week's real world. Okay, I wanted, we have a jobs board and it's jobs.eaterfruit.com. And a lot of people post up their skills and a lot of people, you know what? I did it again. I put the wrong camera underneath the thing. That's okay. It's just, you can tell. It works, but it's like, yeah, it's like, yeah. So you can help miniaturization of existing medical technology. So this is a freelance position and it's to take something that currently exists, miniaturize it, check out the job listing on jobs.eaterfruit.com. We look at each one of these. There is just so y'all who are in the world.  So one of the things to look out for, if you're on LinkedIn, people will approach you and they'll say that they're from other companies that, so you apply and you give them all your personal information, then they'll say, oh, there's an application fee, all sorts of crazy stuff. For the jobs that are listed on eaterfruit, Lamar and I take a look at each one and make sure it's real company and there's nothing going on nefarious. And so far it's had a really good track record of matching people with skills. And it's really focused. It's like, there's no nonsense here. It's like, these are just, these are maker jobs, engineer jobs. But that's happening quite a bit right now just because of the job market. You're probably seeing in the news lots of companies are doing layoffs and more. So people are like looking for jobs and when that happens.  So like, oh, remote, work from home, make $5,000 a week. So just be careful out there. Python on hardware time. Okay. All right. The big and only news we're gonna talk about this week is CircuitPython, 8beta1 and all of the Pico W stuff that's going on. So what can people do? They can watch the show and tell them and see what Jeffler showed off. But why is this such a big deal? What can they do soon? Okay. So CircuitPython 8 has been expressive and wifi based. So a lot of it is about wifi workflow, adding more wifi chip support. And so we did 8beta1. We've been doing a lot of bug squishing. Dan Halbert has just been like crushing the bugs and Jeffler is helping out as well. Good work on them. And then thank you everybody for submitting bug reports. We might also update to Expressive 5x. They did a new IDF release. We're still chatting about it because we only want to do that if it helps squish some more bugs. We have to think a bug list about 30 to get through before we feel like 8 is in a really stable spot. So that's on the expressive side. So Dan Halbert's working on that, fixing a lot of stuff. We fixed a lot of low power stuff. I was a little bit adamant of like, no, we can get 70 micro amps. Like figure out why Dan. And he actually like went out and like spent a week on it and figured it out and got that fixed. So low power for Expressive is also working. And I think he's working on some pin alarm stuff. And on the PicoW side, the PicoW's been out for a couple months and people were like, where's CircuitPython? And we're like, we just got this board the same time you did. But one of the things we wanted to do is once we had, you know, Wi-Fi workflow and a couple other things going, we wanted to go back and make sure that the PicoW had Wi-Fi support in CircuitPython because our Wi-Fi stack in CircuitPython is really good. Like we have a lot of helper libraries and like example codes for like tokens and authentications and our request library is really nice and handles all sorts of exceptions. And people have been able to like download and like stream MP3s and stuff. Like it was very good. We have a really good job of lots of IoT projects, Adafruit IO support. We've had the Azure demos lately, which I want to redo with the PicoW. Anyways, so the good news is that Jepler has been spending a lot of time working on the Wi-Fi stack. So for this Broadcom chip, you know, we had to use this firmware and we have to communicate with it over SPI. Last week we had HTTP working so you could open up TCP and I think also UDP sockets with unsecured connections and that was a really good start. We always love to start with that. But of course it's important for TLS 1.2 support everywhere that we also support that as well. So as of today, Jepler, if you should watch the show and tell did a demo where you can securely connect to an HTTPS site with SSL and it checks the certificate authentication. So it will let you know we actually have a certificate bundle that we've used with expressive chips and the Nina firmware and we copied that into the Circuit Python firmware. So it'll also not just connect securely but it will verify that the certificate you got is signed by a root certificate that is stored within the firmware itself. So first off, we can update the bundle very easily but also it's like really trustworthy security so people can't man in the middle it or woman in the middle it and then we're gonna be working next on adding self-signed certificate support for people who do want, you'll be able to say in a self-signed certificate check this fingerprint or check this certificate public key and also client-side authentication and it's important for us to have a good security for IoT, we really, chips are good enough these days to do SSL. The pull request is still making its way through CI but I think on Monday people can check at the Circuit Python meeting or look at the pull request in Circuit Python you can see a draft PR, subscribe to it and when it's ready for people to check out I think especially with SSL that opens up basically the entire internet we would love to know if it doesn't work on a site we'll add the good certificate. Okay. Okay. And that's this week's Python on hardware I mean of course do check out the entire newsletter but I did want to Great projects in this newsletter by the way. I mentioned that specifically. Yeah. The projects are epic. And on and on and on. And one of the neat things is especially with the PicoW which has been pretty available in low cost you'll be able to do kind of more of these advanced IoT projects that before you needed a heftier device or something that maybe you had a screen or something that was designed just for that but now you get all these projects. Kind of cool. Super cool. All right. We deliver that to your inbox every single week. Go to itforddaily.com completely separate site. Sign up for it. There's other newsletters that we do there too. No ads, no spam. Don't harvest the email addresses. Don't let anyone know about them. The only way we do this is if or why we do this because folks like it. So we're trying to get to like 10,000 subscribers. So we're getting close. So please sign up. That's our like metric. Maybe we'll do a little project with the PicoW that says how many subscribers we have. We can do that very soon. All right. And all this stuff is open source, of course. As always. And speaking of, we have 2,742 guides. So many guides. Yeah. Let's start from the right and we'll work our way over. Noodle Lantern. No paid, we'll show the video. They got our nudes and they were like we want to make art with these nudes. So they made a really cool like sci-fi prop lantern and what we were talking about this on show and tell. What's cool about this prop is it's like, is it a fuel cell? Is it like the bomb you have to diffuse? Is it the key to the spaceport? Like it's kind of like this generic cool sci-fi prop which I really love and it's like it's, you know it's just a very elegant, beautiful like PWM thing that does this cool swirly effect. Is it the key to Vertagon City? Who knows? You don't know. So check that out. It's a really beautiful project and uses a QT pie and our battery backpack friend for the QT pie and it goes into a breadboard proto. So it's a cute little project, very nice all build. Liz Clark has been in a couple of pie leap guides. We're getting close to releasing a new version of pie leap which will add Wi-Fi workflow support. We have a video. We're gonna show the video. We're gonna show the video now. Yeah, this one is how to take a clue board and then with our alligator clip Neopixels you send a program to it and then you can control the Neopixels again with your phone. Leap into wirelessly controlling Neopixels with an Adafruit clue and pie leap. In this project, you'll use the pie leap app to wirelessly load the project code onto your clue. Then you'll connect to the clue with the Adafruit Blue Fruit Connect app to change the colors and animations of a strip of Neopixels over BLE. This strip of Neopixels has alligator clips that can clip on to the clues pads making for a simple circuit for this project. After pairing your clue to the pie leap app scroll to the BLE controlled Neopixels with clue project. Open it and press run it to transfer the project files to your clue over BLE. Your clue will start running the project code. Once you've connected to the Blue Fruit Connect app navigate to the controller module. The control pad lets you choose animations with the number buttons like rainbow and starry night. The up and down buttons affect brightness while the right button scrolls through the animations and the left button turns off the Neopixels. With the color wheel you can select colors to send over to the Neopixels. You can change the saturation by moving the slider. Enjoy dialing in just the right color and watching the fun animations dance around the pixels. What else we got? Okay, Darth faders. So we got those motorized faders in a couple of weeks ago and JP absolutely loved them. He did a really good getting started with motorized faders guide for Arduino and circuit Python. And then we actually sent me a cool project. Somebody made like an art servo project with like waves and I was like, well that'd be a cool thing to do with the motorized slider. It's totally not what it's designed for, but like, why not? So we made this like cool, weird 1980s, goth, sci-fi, fader artistic project that goes on your desk. Yeah, and there's a little video clip. But wait, there's more. Okay, and then finally, we have another project, a team effort here at Adafruit called Cheek Mate. It's a wireless haptic communication system. We actually recently QTFI'd the DRV2605 and of course we've got those wifi QT-pies, the ESP32 S2 and 32 and C3 and S3, all making really small wireless projects super easy now. So we thought, let's see what, and we also have the backpack for the QT-pies. So this is a perfect timing to do a project about how to transmit data wirelessly and then use a haptic buzzer to signal. So I thought we could for- Well, we wanted to do though, and I'm gonna start off with, I'm gonna tell a story. Tell a story. Well, this isn't myth busters, but it's kind of close. We wanted to get to the bottom of some of the rumors we heard about cheating and chess. So this was on CNN today, chess.com. I can't argue with chess.com. They've been investigating all this reports of chess cheating and they say, according to chess.com report, cheating in an over-the-board setting, which means like you're playing two people in the meat space, various message, such as hand signals from a nearby coach or accessing a phone in the bathroom, a hidden device in a shoe or a wire or a buzzer taped to the body. Well, we've got buzzers. So we thought, well, let's see, what would this actually be like? And could you do it? Is it actually practical? We have to investigate the science. We wanted to assess the situation and rectify this rumor. So here is the, and this is in Morse code. Then we're like, oh, and the guide's up, by the way. I guess I can go to this here. Yeah, and it's a real guide. And what's funny is this is actually pretty useful if you want to make a wireless haptic controller. Like there's people who are always like, oh, I want to like notify someone, but not audibly I want to do it with the haptic feedback. The DRV2605 is a great haptic motor controller. So we took a deep dive in this and we wanted to make sure that we knew, okay, so that's possible. Looks like you could transmit Morse code. I think that was queen to C5. And then we wanted to make sure it could go through because it said, oh, like, might be taped to a leg or a shoe or something like that. So. Then it gets a meat. This is meat. And this is it getting the same message transmitted into meat. And it's probably, this isn't probably how people are cheating at chance, by the way. Apparently it's extremely loud and noticeable. Probably not. But it's good to know. Yeah, so we wanted to make sure that we... Science must be investigated. We're gonna delve deep. That's right. So we wanted to make sure that we knew all the ins and outs.  Some need help in other ways. And I think we got to... We didn't want to make any assumptions. They could be flying by the seat of their pants. You don't know. So that project's making the rounds right now. We'll see how it goes. It's like a weird idiom too. Like, how do you fly by this? Yeah.  But I don't think it's gonna work the way you think. Still, the codes up and it's open source and could be recycled into some other nifty project. Yeah. Okay, let's do some factory footage. 3D printing time. And we have two of those projects that I think we alluded to. One is the new lamp and the other one, what was the speed up? And it's a cup of tea. Okay. Kind of cool. It's Halloween. You can build a sci-fi inspired lantern using an Adafruit cutie pie and LED noodles. We 3D printed parts to build a container that showcases these flexible LED filaments. Each LED noodle is squished into these 3D printed holders and mounted vertically. A sheet of pat material wraps around internal mounting plates to resemble a glass container. Powered by the cutie pie RP2040, six individual LED noodles are wired up to the GPIO pins and controlled with PWM. The cutie pie snap fits into a small primer proto board so it's modular and easy to swap for an upgrade. It features a latching push button with a built-in LED ring for turning the lantern on and off. There's also a print-in-place handle with a built-in hinge that allows it to swing back and forth. It's running off a cylindrical LiPo battery so it's portable and will last for several hours. The LED noodles are individually controlled using the PWM library in CircuitPython. The USB port is accessible and can charge the battery with a LiPo charger BFF add-on. In the code, if the button is pressed, the LEDs slowly fade and if the button is not pressed, the LEDs stay off. CircuitPython makes it easy to drive LEDs so you can quickly develop your next DIY project. The enclosure features parts that are 3D printed without any support material. 3D models of Adafruit parts are available to download on the Adafruit CAD parts GitHub repo. To power LED noodles, you want to use a choke resistor to limit the current flowing from your power source. Here we have a 3.7 volt LiPo battery with a 220-ohm resistor wired up to a solderless breadboard. Alligator clips make it easy to connect to your breadboard for testing polarity and your power source. Start by connecting an alligator clip to the cathode end of the noodle. The anode or positive end features a notable hole in the metal contact so it's easy to spot. For more documentation and some demo code, be sure to check out the learn guide on the Adafruit learning system. We hope this project inspires you to check out LED noodles and use CircuitPython for your next project. And don't forget, if you want to learn how to make all this stuff and more, you can hang out with Noam Pedro every Wednesday for 3D hangouts. Okay, we're gonna do two back-to-back IONMPIs. That's right. Two eyes. Yeah. With a cup of teeth. You ready? Yeah. Okay, this week, the first one is U-Blocks. That's right. What is this week's IONMPIs? I love featuring U-Blocks. They have such good quality products. They've been making GPS modules for 20-ish years. You know, I remember when they first came out with their first series and I was like, wow, these are really, this is really cool that they have GPS units that are so sensitive. Their specialty is the high quality, sensitive, a lot of information. There's cheaper GPSs, but they only give you NMEA data and U-Blocks will usually give you a lot more. And they're a lot more configurable and customizable. So their 10th generation of GPS modules are out. The MAX-M10, there's the S-Series and the M-Series. Both are very tiny. I'll show them on the overhead later, but these are, you know, this is like a centimeter by a centimeter. They're very, very small. They don't have the antenna built in, but they're very powerful. And like I said, this is the 10th generation. So they're just improving and improving on the technology. So the MAX-M10, like I said, this is their super miniature module. You do have to add an external antenna. However, you know, data does come out of it. You know, once you connect the antenna, it can connect to up to four different GNSS satellite systems. And it's been compatible with some previous products, not all of them. I mean, I know like some of them were bigger. They've gotten smaller since then compared to like the rectangular style that were popular for so long. So there's the M10M and there's the M10S on the right. And they are slightly different. So the M10M, I mean, they're both basically the same core on the inside. They came to the same GPS, GLONASS, Galeo and Beidou. So GLONASS is Russian, Galeo is European, Beidou is Chinese. I believe GLONASS is up. I think Galeo and Beidou are not completely up yet, but I have to check because I don't subscribe to GPS daily. So I'm not totally up on which GNSS systems are up and running. Both have UART and I2C. We'll take a look at that. The M10S has slightly higher sensitivity because it has an additional low noise amplifier and saw filter. It also uses a temperature compensated oscillator that's the T under oscillator whereas the M10M has the crystal oscillator. So it's a little cheaper. But it's, again, not as sensitive. So basically, if you want low cost, go with the M10M. Another nice thing is it goes up to five volts to 1.8 to five volts towards the M10S. It has a little bit of extra hardware in there, temperature compensated, only up to 3.3 volts. But it gets you another, I think it'll show another 3 dB of sensitivity while tracking. So what it looks like, and I think we'll look at the pinouts in a bit, but basically inside is, it's a microcontroller that handles the, grabbing the data and doing the calculations and then converting it to the interfaces. So there is firmware running on it. The modules you can see here, it has the RTC crystal and then the temperature compensated oscillator optional. And then the low noise amplifier and the saw filter also optional on the S series, not available on the M. There's power, there's VDD IO, there's VDD RF. There's a couple power supplies and of course there's a V backup, which is the coin cell or I think you can also use like small rechargeable alkaline or lithium coin cell, solderable coin cells for battery backup to keep the RAM backed up so you don't have to re-download the entire Almanac each time. This is where you can see all the specifications, but basically the detail you want to look at for the difference between the two is in acquisition underneath sensitivity. The M10M has a negative 164 DBM and the M10S is a negative 167. It also has slightly faster aided start. Otherwise it's pretty much the same. So just tracking is a little different. Otherwise they all have similar specs. And this is the pinout, very simple. I like how it's very straightforward. You can see there's right hand side, there's time pulse out, that's pulse per second. There is the battery supply, the reset pin. Left has I squared C, right has UART. There's safe boot end because I think you can upload the firmware if you have custom firmwares because again there's the mic controller inside. And then there's an RF and LNA area which you'll talk about when you have a active antenna, you can use it to power the antenna and also do some detection. Okay, so you are interfaced. So, you know, standard, your NMEA output is classic for GPS units. If you need that, you got it. This one is going to be default 9,600 BOD, but you can see it goes up to almost one megabit or down to 4,800. You know, all these standard BOD rates that you can use, of course, if you haven't, you know, giving you 10 hertz updates and you have all the sentences enabled, you'll want something fast like 115 or 230 kilobit per second, eight and one. And then what I really like is they also have I squared C.  So as each byte comes in, you have to quickly put it in and into your buffer queue and then keep track of it. Whereas I squared C, it has its own internal buffer for I squared C. And then if you see at the bottom there, the register layout, most registers aren't used, you use registers FD and FE to read the number bytes in the queue. And then you can just read continuously register OXFF to get data bytes in. I don't know exactly how big the queue is, probably like 64 or 128 bytes or something. Very handy, you can run it at 400 kilobytes. One thing I do want to mention, I'm sorry, kilobits per second, there is a clock stretching interface. So, you know, some chips do not like clock stretching. Just something to be aware of, you know, earlier Raspberry Pis didn't do a great job with clock stretching. You'd have to lower the frequency rate. So you'll have to figure that out. I don't know how long the clock stretches for, but it is in my controller inside. It's not a hardware I squared C interface. These things are so small because they do not have a antenna, like some modules that you might be familiar with. And so you'll have to add either passive antennas what a passive antenna looks like. In this case, it has a UFL connector or an active antenna. Active antennas are powered by clean 3.3 volts, biased into the RF line, but of course you're gonna get much better performance. We know with the addition of the draws an extra like 10 to 50 milliamps, whatever it takes. This is an external antenna. So which do you use? It's totally up to you. You get to decide because you get to put the circuitry in. So this is what it would look like for an active antenna. You see there's the antenna supply. You have an RC filter and inductor to feed it into the antenna RF in. If you're using a passive antenna, you just leave all that out. So super easy. You decide which one it is. There's also a antenna supervisor circuit, which I kind of think is interesting. I think this is really handy because a lot of times people, I've noticed people using, you know, they're using antenna and it gets disconnected or the UFL or there's a short and like my GPS doesn't work. It's very hard to debug a GPS because basically either you get a fix or you don't. So having an antenna supervisor is really handy.  They do give you the layout. So like this is the three pin circuit. So it lets you detect open, closed, shorted, whatever is connected. It basically does everything, but it does require you to see comparator and a bunch of transistors. That said, if you wanna build a really rigorous GPS into a product and you want to alert people that the antenna is not working or maybe they kicked it the wrong kind of antenna, the kind of thing is what makes your product a little bit better than just like, hey, you know, either it works or it doesn't. Cause again, GPS is so opaque. Like either you're getting NMEA sentences and either there's a fix or there isn't. It usually doesn't tell you why you're not able to get a fix. Another thing that I thought was interesting as I was researching this is that they actually came up with a kind of a cool idea. I'm hoping I'm describing this correctly, but they have things stream, things stream, things stream, which is their IoT asset management, you know, service, cause they do wifi and they do RTK and they do GPS. So it makes sense that they have their own IoT backend that you can stream data and I believe they use MQTT. But what's another interesting thing is that normally when you have a GNSS receiver, right? It's, you're not getting the data from the satellites. It's like telling you what your location is. You get these, you know, time pulse signals and you take the calculation of the deltas and you figure out like, okay, based on like the movement through space and the almanac of where all the satellites are, it'll calculate for you, you can calculate your location by using triangulation. However, that does take energy and time and you have to have that almanac to know where every satellite is. And so that's why it can take like 45 seconds to do, you know, a cold start. And then this idea, which is like, well, what if you don't do that? What if you don't have to keep track of the almanac? You don't have to calculate. You just, as long as you can get a couple signals from three satellites, you can upload it to their service and their service will do all the math for you. So it's really, really fast because you don't have to do a cold start. And then as long as you do have some wifi connectivity, maybe you have like an NBIOT, you know, you can quickly turn it on, send some packets out of Laura, send out that timing data to their service and then it will calculate the location for you. So it's an interesting idea because on one hand, of course, you have to have wifi or cellular connectivity, but you don't have to keep track of as much, like the GPS doesn't have to do as much work. And that's kind of an interesting idea, like offloading the GNSS calculation. And then finally, good timing, there's actually a webinar that they're doing with DigiKey in a week. It's a week from now. So sign up. If you go to Ublox or DigiKey's Twitter account, they've just posted it. It's also, if you just Google for Ublox, accelerate your wireless solution development, uses their Explorer IoT, Humanity and Temperature Centers, IMUs, Sincereon, Micro-E, looks like the SCD-40 or 41 there. Looks like a really cool way to get started with, you know, their IoT platform module that has wifi, NBIOT, cellular, Lora, Bluetooth, and it's got STEM and QT and Quick Connectors on it so you can add more sensors. And I think the webinar is free and you can pick up the Explorer IoT Kit, which has one of these, I think Max 10 GNSS modules inside of it. So it can be a really great way to get your asset tracker or GNSS project up and running. Available at DigiKey, it's in stock. That's right, 9,000 of them. It's over 9,000. So they have the S in stock. I think the M isn't, but I will say one of the things is that like, this was not in stock when I first started the IMMPI, but I was like, they were so cool, I thought I would do it. And then like two days ago, suddenly they came into stock. So I did get some, I can show them on the overhead. Okay, you wanna show that video after that? Yes, but I just wanna show this really quickly. They have a cute little video, but I just wanna show how unbelievably small they are. I'm gonna have to let it refocus cause it's so tiny. Very tiny little module. So I mean, it's amazing how small it is. Of course you'll need the antenna, but the antenna usually goes on the outside anyways, and it comes in a tape and reel. Okay, here's the video, see you on the other side. Yeah. All right, we're gonna take a little bit of break in between the IMMPIs cause we're doing two this week. That's right. Cause we wanted to catch up because last week we got super busy. In regular old Adafruit news though, in a wing, that's the code. Use it in the store to buy all sorts of things.  You can maybe, you can buy some of Chai's and you can stick up your body. No, you can't do that. Don't do that, you're editing that out. We're editing that out. Don't do that. All right, let's do the next IMMPI. IMMPI. Okay, next up is Scotch brand, which everyone's probably familiar with, I don't know the most well-known brands in the world, but what do they have that could possibly be a new product that is gonna be in here this week?  Why are you highlighting scissors? And the answer is have you ever had bad scissors?  On Twitter today, I saw it was National Scissoring Day and it wasn't what I, it's a wrestling thing, by the way. I thought it was something else and I'm just like, oh no. And I'm just like, what is this? Well, not a special media. But it's a wrestling, like wrestling move or whatever. So it's very timely we're doing this. These are really great scissors. And, you know, I used to sew when I was younger, but now I do electronics and, you know, my pair of these scissors, and I got a couple pairs of these, are so handy. And what I really like is, you know, once in a while, I'm like, here's this most advanced electronics. And sometimes I'm like, here's a tool that you just toss into your DigiCart. And then next time, if you're checking out, it'll be there waiting for you. And then when you get it, it's like a gift.  These are the precision scissors. I did get two pairs, one I kept at home and one I brought in. So I'm gonna put on my desk. They're really smooth. They're comfortable. You can use them. I'm right-handed, use them with the right hand, but apparently they're left-handed as well.  And they're great for, you know, I use scissors all the time with electronics. I'm cutting open packaging.  There's always materials and stuff I'm cutting. I'm using my scissors all the time. And really good scissors are really, really satisfying. I found this like ASMR video about gliding your scissors. It's so nice. Again, I was used to cut fabric, but if you do, look, you get two of these, one can be used for paper, one can be used for fabric.  And I found this and I was actually kind of like a little bit weirded out by this comic because I was like, wow, that's an MIT mug and it's the correct logo, which is a very big deal for me because they changed the logo like a couple years after I graduated and I think I don't like the new logo. So I was kind of like, why is, why does this person pick the correct logo? And then I realized it's Jen Lopez who used to write for Voodoo and do cartoons. And I think probably lived in Senior House. Really cool. And she has like a company now that does quilting and does comics about engineering and making and crafting. So check out her comic series while you're waiting for your scissors to ship because this is both a very funny comic. It's very nicely drawn and she's got a very cool maker company. There's about 10 different scissors available.  I picked up two of the multi-purpose. They also have, of course, the precision, but there's basically a whole set and they've got a bunch in stock and they're super inexpensive. They're like under 10 bucks a piece. Another thing while I was looking for more deets about these scissors is I realized 3M, again, it's another thing to do while you're waiting for your scissors to ship, they've got a cool science at home experiments page with like dozens of projects. And it looks like they even got some celebrities come by and do some projects as well. But during COVID, but we can benefit now even if kids are back in school, they just posted a ton of science and maker and STEM projects that you can build with stuff around the house using, like you guys would expect, scotch tape and scissors and cardboard and whatever materials else you've got. So check it out. These are really awesome science experiments. Great for young kids, classrooms. If you have to kill some time on the weekend because it's rainy out, maybe the kids are indoors for the holidays and you've got to entertain them and keep them off the Netflix. Check out some of these science at home experiments. They are really heartwarming and they teach good science too. Good crafting. Available as a key. They have some in stock. Yes. And do you want to share data? I could do the ASMR of scissors. So I got a pair. I was like, well, you know, I guess it's a good excuse for me to get extra pair of scissors. Here's the thing. If you have used somebody's fabric scissors to cut paper and now they're angry with you, buy them another pair of scissors and be like, and it's like a peace offering and they'll be happy. So this is, it's really nice. That nice, nice smooth action. Yeah, these are, so these are the, these are not the precision. I will admit, I got, I kind of miss clicked. I ordered the general purpose scissors, but they've got the nice soft, this is like hard plastic and this is like soft siliconey rubber. So they're very comfortable and they've got a little place to you put your fingers and ooh, they're so nice. So anyways, I really like these scissors. All right, and we have a little short video too. Oh, and then also, by the way, the tips are nice and strong too. They do the thing. You actually want this where there's, they're curved. See how they're not, they're not flat. That's actually good. It means you always get a really strong cutting edge and you can nip with the ends very easily. Okay. There are thousands of tasks where you need scissors and Scotch brand has the right scissors for any job. Scotch multi-purpose scissors are perfect for everyday use with a soft grip handle and quality stainless steel blades. The right choice for daily cutting needs. Great for around home and office, anywhere you need to cut. Scotch precision scissors get down to detailed cutting business with smooth cutting action. Precision sharpen blades and a variety of lengths for precise cutting big or small. The scissor when details matter. For tough, sticky tasks, Scotch precision ultra edge non-stick scissors have three great features. Titanium coated blades that stay sharp beyond 100,000 cuts. The scissors for hard-working cutters. Non-stick coating resists build-up of adhesive residue for cleaner cutting and a soft grip handle for comfortable repetitive cutting. Scotch precision ultra edge non-stick scissors are making the cut. Scotch multi-purpose precision and precision ultra edge non-stick. High quality scissors for every task. Okey-dokey and for new products this week we're gonna do this. We have a revision this week. It's a light week. Yeah, so we have one thing that we wanna go over because we're gonna get out of here pretty soon. We have two NPIs. But let's do a new product.  It's a light week, but don't worry. There's a lot coming. It's just, we had a lot of new products last week and I've been doing a lot of revisions. Don't worry, there's more on the way. You're gonna love it. But this week we just did a one revision one to get a product back in stock. So the INA 219. Oh, I gotta say this, the star of this show tonight is the product. Is the product. Our staff, our team, all the folks who makes this possible, our community. Everyone here at Adafrit. Not the guy who posts on Twitter. He's in fired. Yeah. He's been sacked. The person who's responsible for sacking him has also been sacked. Yeah. We gotta accept it to be the new cast members on SNL. So we're ditching this electronics biz and we're just gonna do parodies and puns from now on. Anyways, the new product of the week is. The INA 219 feather wing shown here. It's great for doing high or low side voltage and current measurement. Not a new product because we've had this for a while. This is the version we used to have. Oh, it's so cute. It uses the SOT 238 version of the chip. Use the 219B version, although we never really said the chip specifically was the 219B. However, that package of the chip, we can't get right now, but we can get. Is the SOIC version. So we just rotated this. Yeah, we have to retake the photo. But I wanted to line up. This photo is from the space station today. This went on, a lot of people don't know. This was on the SpaceX launch today and this is how it was shot. What do you do? Let's look at the next photo because it's a little bit more clear. So basically, instead of that tiny SOT 238, we're now using a SOIC8 chip instead, which means that the jumpers for the address move to the bottom. And we also may use the 219A or 219B. The 219B I think has 0.3% precision. The 219A has 0.5. Here's the thing, the resistor is only 1% anyways.  It's still an excellent, excellent chip. But just, we wanted to keep it in stock. We didn't want to wait, you know, we're getting lead times of another six months until we get the smaller chip version. We'll revert to that when we get back to it. But for now, again, we wanted to get this back in stock and doing a quick PCB revision to use an SOIC size chip did the job. It otherwise works exactly the same. It just looks a little bit different. Surprise.  Don't forget, in-waying, it's a code. Let's do top secret. Go over to discord, a-different.it slash discord. Put your questions in there. Let's do top secret and then we'll get to the questions I have lined up. Okay, this week, this is one that we just filmed. Just a few. Just testing on a profile. Feels like moments ago. It was yesterday. All right, lady, what is this? I'm testing out a new design I made. We actually just published a project that uses WLED on an ESP32 QT Pi. And Erin was like, oh, I wish it was an easy way to level shift Neopixel signals for LED work on QT Pies because they're all three-volt logic and Neopixels really want five-volt logic.  You can select different signals. Mosey, SCK, RX, TX, SEL and A3 are some options and there's a signal pin here. And this is a 74 AHT125 G1 level shift or so it'll shift the three-volt signal to five volts and then it also gives you a five-volt signal from the USB line. So for strips of up to like 100 pixels you might be able to power directly from USB or clean Neopixel signaling. Okey-dokey, and that's this week's top secret. I got a bunch of questions. We do, I have some lined up. Here we go. First, a completely random question that Cherry used to make the locking MX switches. There would be a great fit for the Walkman a couple of weeks back. Also sourcing new ones would be really nice. Yeah, I know what you mean. I've not seen anything like that but they would be really cool. Okay. I agree. The inner here is a possible to import libraries like Mapplotlib, NumPy, OpenCV to CircuitPython. It's a good question. So CircuitPython that runs on microcontrollers cannot import something like OpenCV or NumPy or Mapplotlib. However, there are some similar libraries. Like instead of NumPy, we have Micro Shoot ULab. Yeah. Yeah, we have ULab which is NumPy-like. It doesn't implement all of NumPy but it does have some array optimizations. It's a sped up version of, because built in C, it's built into the core. What you can do instead is if you really need OpenCV, you need something like a Raspberry Pi computer to do it with, you can run CircuitPython libraries in code by using Blinka which is our layer of, it's a library that basically lets you use all of our sensors on something like a Raspberry Pi computer. So that way if you want to use these advanced libraries you'd run Python 3 on your single board computer and then get sensor data to do your data analysis with using Blinka which is a CircuitPython library layer. Okay. For the haptic communication system, do you need to be a back end developer? No, you can use the no code stuff from Adafruit IO and could someone possibly install a backdoorness? No, not really. I mean if you're using CircuitPython you can inspect the code and everything. I'm not sure I get that. It's all open source software. It's all open source. Okay, next question. Speaking of pins and headers, any way to engineer an RPI camera onto an RP, sorry, a Pi 400 which lacks the camera header? It's a really good question. I don't believe that they have even a socket for it so you want to use a USB camera. Okay. It's one of the, you can't use them the microphone, there's no audio and there's no camera. Any RA8875 upgrades? Not only are no upgrades, that chip is basically being discontinued. It's kind of a bummer because I rather like it but it's not long for this world. The price is only going up and up and up. Eventually we'll no longer be available. All right, this tutorial seems to be getting all the questions this week. So where do you get these little tubes? Oh, this is actually a really great question. So these tubes are, they're called soda bottle preforms and they were used in the POI project. And where can you buy them? I mean, I think you can Google for soda bottle preforms but I remember Phil be mentioned. Yeah, I think I still have these from back then. I haven't charged these up in a while, but these used to be like two liter bottles. Yeah, they're what they're used to make two liter bottles. Yeah, they heat it up and then they get expanded. So these light up and you spin them around. Honestly, I would just Google for it. I'm sure they're available from like crafting supply stores or maybe like Amazon or something has them available. Okay. They're really great. They're like waterproof and they're durable and they're very easy to use. And of course they have a standard cap top. Yeah. So good for a waterproof project and they're quite large. You can definitely shove a lot of electronics in there. How hard would it be to make a host transceiver for a Bluetooth headset to take the place of the smartphone or computer? For example, in IndraCom. Oh boy. A host for Bluetooth audio. ESP32 may have example code for it, maybe. Although I think they only have client side. I know Raspberry Pi could do it because it has a full Bluetooth stack and people connect their speakers to the Raspberry Pi computer. That's probably the easiest smallest thing you could do. Can you connect a low power three volt PIR directly up to a PCF 85, sorry, 8375? Probably. I don't see why not. If it has like a totem output, like a push pull output, it should work, but I'll say I haven't tried it. All right. Last two questions of the night here. I got some MCP 23017 ESP NDs, but nothing in the datasheet is ND, some kind of nomenclature I don't know about. ND is just DigiKey's new DigiKey part number indicators. You just ignore that. Okay. Next up, one will be more colored OLEDs with high resolution and small form factors like two inch or 2.3 inch available alternative to the ISP TFT. I don't actually see a lot of new OLEDs coming out, especially not in the maker hobbyist pricing market. To be honest, all of them are Mipi. They're not going to be SPI if they're OLEDs for phones. Instead, just use IPS TFTs. IPS TFTs look really good. All right. And here's another question. How hard would it be to make a custom Bluetooth headset? It's kind of like a pain.  They're really low cost and they're really simple. If they happen to do exactly what you want, you're good to go. But like firmware, it's really hard to write firmware for Bluetooth audio stacks. It's just like, it's just not, like it's just not well documented. It's not really common. It's not like Bluetooth that I don't do with a lot of example code, like Bluetooth audio. It's like either, if the examples are great, if it isn't, it's like, you really don't want to be messing around in that stack.  Okay. And that's our questions this week. Thanks everybody. All right, so that's our show. Don't forget to code all the way up to 11.59 p.m. tonight and wing, get you 10% off in the store. I think it's free stuff too. We'll see everybody next week. Thanks for helping us get to the bottom of a lot of mysteries this week. We'll see everybody next week, 8 p.m. Ask an engineer. Thank you, Jesse May behind the scenes. Thank you, Jesse May. He's been helping out with stuff. This has been Native Fruit Production. Here is your moment of Xenar. It's all my fault. You're the blame me. Yup.


Well, I'm very pleased and very excited to receive this award from the Brain Foundation. I'd like to thank you all very much and the donors who made it possible. I'm really excited to tackle this question because it addresses the worst kind of problem, which is a problem that people believe has already been solved. So let me explain what I mean by that. So to start with I'd like to acknowledge that it is widely supposed that Tasmanians are a bit slow and that we frequently have two heads. But what's not quite so widely known as the reason behind that and the reason is that Tasmania soil is very poor and deficient in iodine. And that's a problem that the native Tasmanian solved by having a diet that's rich in seaweed and shellfish, which naturally supplements them with iodine. But when European settlers arrived in Tasmania, the vegetables and the livestock that they raised on this iodine poor soil were lacking in this essential nutrient. And what that has is both metabolic endocrine consequences, and so people develop enlarged thyroid glands of goiter, which can frequently enlarge to the size of one's head. And also has profound implications for developing babies because of the role of thyroid hormone, which depends on iodine levels, in the development of the brain. And in extreme cases, this leads to a syndrome known as cretinism, which is a lifelong cognitive dysfunction and sensory processing deficits. So in the 1970s and the 1980s, people began to understand and really unpick the role of iodine during gestational development. And this was a problem that appeared to be solved. And so iodine supplementation has greatly reduced the incidence of cretinism amongst the millions of people across Southeast Asia who lived in naturally iodine poor regions and who experienced a large number of cretinism in the in the live birth population. But sorry. So the problem appeared to have been solved. And in Tasmania, we iodized the salt and we put iodine in the bread. And even the iodine and the disinfectants that were used in dairy farms added a substantial iodine load to the milk supply as well. And so Tasmanians were iodine replete and the problems appeared to go away and everything was good. But then they stopped using iodine-based disinfectant in dairies and for a period of time in the 1990s before it was mandatory to put iodine in bread. It was possible for people to eat a healthy diet and to have only just barely enough iodine to get by just based on the normal levels that were found in food. And this is okay if you're not pregnant. But when you're pregnant, your need for iodine rises and a population which is mostly okay for the level of iodine in the food it can have or can mask levels of mild iodide deficiency among the pregnant population. And this is actually quite widespread in Australia. So in Western Sydney and in parts of Victoria, it's been documented that many expecting mothers have a mild level of iodine deficiency. And because we know that severe iodine deficiency affects the brain, it became logical to look for deficits in the offspring of these pregnancies. And my colleagues John Burgess and Kristen Hines from the Menzies and the Royal Hobart Hospital looked at a cohort of mothers who came through that period of mild deficiency and have been tracking their offspring since. And it turns out there is a long-term consequence. So these kids are now 13 years old and they've been tracked through their schooling and the results of their standardized testing for nap land and other academic tests have been evaluated and they appear to have a mild but persistent and consistent deficit in language processing. And that seems to be about 10% on things like language comprehension and spelling and things like that. And it's held up again at more detailed testing that they've received at the age of 13. So it seems like there is actually a problem there that we were unaware of. And when I heard about this research, I suddenly thought to myself, well, I know a protein which is essential in the functioning of the auditory system whose expression is regulated by thyroid hormone. And thyroid hormone depends, of course, on the level of iodine that's present during pregnancy. And so we believe that the neurofilament protein, which is an essential structural component of the fast signalling fibres in the brain, and therefore important in sensory processing and perhaps the building blocks from which we develop language is going to be profoundly affected by even a mild deficiency in iodine during pregnancy. And so the work that the Brain Foundation has chosen to support is going to establish a model of not severe iodine deficiency, but mild deficiency in laboratory mice. And we're going to look at the offspring to study the expression of this protein, to look at the ultra structure of the fine fibres in their brain, and lastly to test them for sensory deficits. Because if we can establish that body of evidence, then we can go to the Australian public and we can say it's essential that you get proper iodine nutrition during pregnancy. Because this is a hidden blight that might be preventing our children from achieving what they can at school and throughout the rest of their lives. So I think this is a very important first step in establishing the genuine biological underpinning of what might be a hidden problem among Australia's children. So thank you very much for giving us this award.


The first scripture reading for today is from the book of Isaiah chapter 61 verses 1 through 3 This is the word of eyes the word that Isaiah speaks The spirit of the Lord God is upon me because the Lord has anointed me He has sent me to bring good news to the oppressed to bind up the brokenhearted to To proclaim liberty to the captives and release to the prisoners To proclaim the year of the Lord's favor and the day of vengeance of our God To comfort all who mourn To provide for those who mourn and Zion and give them a garland of instead of ashes the oil of gladness instead of mourning Notice that this piece is by one of our own Alfredo Freddy Barahona and his son Ernesto did the recording of this Jorge Elvijo Palencia song Profeta Pero la historia no Callarra y le impondrán el silencio Pero la historia no Callarra con su evangelio en la mano Monseño Romero quiso Hacer justicia y la hizo su albillano Por qué su voz fue el aliento que defendió al campesino Iluminando el camino la libertad de este pueblo Podrán matar al profeta Pero su voz de justicia no y le impondrán el silencio Pero la historia no Callarra y le impondrán el silencio Pero la historia no Callarra Pecado fue querer Que los obreros comiera Que un padre nuestro tuviera Para rezar lo comiendo Cuando Dios no hace justicia Por qué no entienden los ricos En los pobres sale el grito que aprendieron del profeta Podrán matar al profe pero su voz fue justicia no y le impondrán el silencio Pero la historia no Callarra y le impondrán el silencio Pero la historia no Callarra Su muerte no es coincidencia Debe temblar los tiranos Son ellos los que en sus manos Lleva la mancha del crimen Y toda la oligarquía Torpes de tanta demencia Afirmado sus sentencias Comienza ya su agonía Podrán matar al profeta Pero su voz de justicia no y le impondrán el silencio Pero la historia no Callarra y le impondrán el silencio Pero la historia no Callarra At this moment in the service We would like to honor the friends and partners Of Kairos who have passed away over the years Their work and their dedication not only helped shape Kairos But contributed to justice efforts around the world Some have been gone for many years But with others the grief is still fresh We named them with gratitude for the care and love they shared And the work they did and we ask comfort for all those Still mourning their loss So let's take a moment to gather ourselves Acknowledging the loss and honoring the lives Of those who have passed but who remain in our hearts And I will name them here Kimi Pernia Domico Digno Ochoa Esperanza Amirres Miranda Pascal Cabangula Kibembi Mary Ellen Natal Mary Orr Crispin Beltran Also known as Cabel Mariano Abraca Bishop Samuel Ruiz Father Joe Dezen Christopher Lind John Mehevick Topazio Renoso Warren Allmond Sister Doreen Kirby John Dylan Arthur Manuel Dorothy McDougal Audrey McClelland The Reverend Fletcher Stewart Dr. Bonnie M.

Indigenous women, girls and gender non-conforming people who have been murdered or disappeared. Human rights defenders killed for their efforts. Migrant workers who died on the job or due to complications tied to their labor. Those who have passed from complications of COVID around the globe and all for whom injustice contributed to their death. We pray for comfort for all who grieve the will to change the structures that contribute to oppression and death and strength to see our grieving and our changing through. Let us now join in a prayer or thanksgiving. We sing a song of thanksgiving today as we remember the past 20 years of spirited action for justice of the work and ministry of Cairo's.   You are our ever present help in time of need. We can and do turn to you in the midst of our troubles and Lord our world is full of difficulties. We pose in the midst of all that is unholy, unthinkable and undeniable to look within and offer our gratitudes for a day that has dawned a new as we celebrate 20 years of spirited action for justice. We rejoice that we have voice and head and heart so that we can love one another love you and love all of your people for the work of influencing policy change towards dignity of creation for the work of influencing policy change for the work of dignity of all people we are thankful we celebrate the abundance in our lives and that we can share it with the world in jubilance and grace we offer ourselves and all that we are and have to be your justice and peace in the midst of all that is unholy and thinkable and undeniable for the past 20 years many many things to thank you for creator God receive our praises and thanksgiving in the name of Jesus pray amen and now let us move into a prayer of confession Lord we come in prayer to you burdened with our unhappy business all the deeds done under the sun that we would rather not remember the sound of sin in our world the sin of the doctrine of discovery used as justification to seize land subordinate and enslave infecting our assumptions about people of other ethnic groups and nations the sins of colonization past and present including our participation in the systematic oppression of indigenous sovereignty language culture and spirituality the sin of white supremacy this blight on our hearts our communities our institutions the systemic oppression of a racial group to the social, economic and political advantage of another and many other sins too great to count or name hearer of all you know too clearly the sorrows of our world forgive us our sins and help us right the wrongs we've done give us words of repentance to share with those we've wronged bringing courage to amplify the voices of the most vulnerable among us and a resounding love for the lowest and the least most of all tune our ears to the voice of Jesus so that always and everywhere we might hear his song of peace for every creature under the sun amen let us move into some words and prayers of assurance the God who challenges us is also the God who encourages us the God who confronts us is also the God who accepts us and loves us unconditionally may the God of mercies through the death and resurrection of the Christ send the Holy Spirit the forgiveness upon us to grant us pardon for all the wrongs we have done both individually and communally as a country as a people and as churches especially wrongs done towards our aboriginal brothers and sisters through adherence to the doctrine of discovery the sins of colonization and oppression and our attitudes of white supremacy through this acknowledgement may our provident God give us humility and sorrow for our sins and may the creators great light shine out of this terrible darkness giving us courage and wisdom to right these wrongs glory be to God whose power working in all of us can make us infinitely able to accomplish true reconciliation and healing far more than we could ever ask or imagine with a strong will to change unjust structures glory to God in the highest and on earth peace to all creatures and people of goodwill we offer this prayer and all the holy names of God Amen I'm going to read to us from the story of Esther from chapter four we come to Esther's story at a time when she is being challenged to stand up to the king of Persia in order to save the Jewish people from massacre she and her cousin are exchanging messages our scripture begins with Esther speaking all the king's servants and the people of the king's provinces know that if any man or woman goes to the king inside the inner court without being called there is but one law all alike are to be put to death only if the king holds out the golden scepter to someone may that person live I myself have not been called to come into the king for 30 days when they told Mordecai what Esther had said Mordecai told them to reply to Esther do not think that in the king's palace you will escape any more than all the other Jews for if you keep silence at such a time as this relief and deliverance will rise for the Jews from another quarter but you and your father's family will perish who knows perhaps you have come to royal dignity for just such a time as this then Esther said in reply to Mordecai go gather all the Jews to be found in Sousa and hold a fast on my behalf and neither eat nor drink for three days day or night I and my maids will also fast as you do after that I will go to the king though it is against the law and if I perish I perish every once in a while we come up against a Bible story that does not sound like a Bible story more like a soap opera the book of Esther is one of those odd and colourful biblical narratives it's nestled between Nehemiah and Job in the Old Testament five centuries before Jesus Christ there were pockets of Jewish people living throughout the powerful Persian Empire Esther is a vivid account of life in the court of the king of Persia it's a story worth telling but to make a long story very short the king needs a new wife a group of young women are brought to the court for the king to choose among these women is Esther Esther is an orphan adopted by her cousin Mordecai Esther is Jewish a fact that she must hide if she wants a chance to be queen the king along with the rest of the royal court is delighted with Esther she is sweet tempered and lovely to look at Esther proves immediately that she is not just a pretty face with help from Mordecai she saves the king from a would be assassin the vindictive villain of the peace hatches a plan to kill the Jewish people to whom Mordecai and Esther belong Mordecai goes to Esther for help to prevent the attack by intervening with the king but she is at a loss because even though she is his wife she would be risking her life to approach the king until she is invited and the king has not granted permission for him to for her to speak to him Mordecai challenges Esther with these words he says if you keep silence as such a time as this relief and deliverance will rise for the Jews from another quarter but you and your father's family will perish who knows perhaps you have come to royal dignity for just such a time as this in other words Esther is risking her life by not speaking to the king she is condemning others to death if she stays silent it's a no-win situation after a great deal of prayer and reflection Esther decides to put herself at risk she intervenes and Mordecai and the rest of the Jewish people are saved presumably everybody lives happily ever after Esther's story has all the best elements of tragic comedy, beauty queens and intrigue, betrayal and loyal heroes but as I said before it's a strange kind of Bible story because you may have noticed that God is not mentioned at all yet God is in this story God may be hidden but God's fingerprints are all over this one God has gone incognito but where where in Esther's story do we see God I think we see God most working in Esther's character and her actions she's beautiful inside and out she's put severely to the test and she chooses to put her position at risk her life at risk for the sake of her people above all she is able to recognize within her circumstances the silent working of divine providence she has become queen for such a time as this God has placed her in a situation in which she must discern God's call to action in a week or to stay silent if I can borrow a phrase from the author of Esther's story perhaps it is for such a time as this that you and I have been created perhaps God has gifted us with our particular voices and treasures for such a time as this it is for such a time as this that God has called us to be kairos those of us who are disciples of Jesus Christ believe that we are caught up in the story of God's mission to the world we are part of something that is much bigger than our individual selves we belong to the story of God in the world and that means that we have been given roles to play and a place in the narrative we have a purpose and a call there are at least two aspects of call that are difficult for many of us the first is discerning what exactly God is calling us to do and be how do we know what God is saying and are we hearing correctly what is it that we are being prepared for and urged to accomplish how are we being prepared to make visible what is hidden once we have fully understood the nature of our call if indeed we can ever fully understand then are we willing to do what God has asked will we risk ourselves our comfort our security will we speak or stay silent will we go or stay put will we give or will we keep or will we maintain the status quo whether we as characters in God's divine story are willing to take direction from the Lord of the universe is usually up to us we are not puppets on a string we are free to say yes or no we are free to stay silent at such a time as this we are free to ignore the insistent whisper of God's call none of us have the fate of a people or a nation resting on our shoulders like Esther did our decision to heed a call or to ignore it most likely does not have far reaching or catastrophic implications but there are urgent consequences associated with our decision to do what God calls us to be what God calls us to be if we are being called to reach out to neighbors to feed them or clothe them or advocate for them then there are consequences for our neighbors if we choose not to do so if we are being called to speak out for justice then there are consequences for those whose lives are threatened by injustice if we choose to stay silent all this is a reminder that we are connected we live not as individuals but as a community of faith it is a reminder that you and I have been born for such a time as this Cairo's time to live as the body of Christ in this time in this place for this moment sustained by the gracious love of creator's son and Holy Spirit may God's infinite gentleness and wisdom guide us to recognize the divine voice in our ears even when it is almost too quiet to hear and to discern exactly how it is that we should respond to the time in which we live Amen I will now be sharing a song from Verney incredible partners from the Philippines and she actually she's with us now and it's morning time and we were together this morning which was night time for Verney and this incredible incredible gathering and so now we're going to hear from Verney who wrote this song actually as a reflection on everything that she was hearing from our other partners all over the world who have been with us in this amazing gathering Lidali Lidali Lidali Lidali Lidali Lidali Indigenous peoples march to say we're struggling to be free fighting for our rights to land generations will survive learning organizing mobilizing to be free in unity and solidarity our power the world will see Lidali Lidali Lidali Lidali Lidali Lidali people of the Philippines uniting with community Church people for the land working with communities learning organizing mobilizing to be free in unity in unity solidarity that is our ministry Lidali Lidali Dali, you the 20 years, Kairus walked with us, wait our passion to do the rising, mobilizing to be free, tighter partnerships and solidarity, a change world we will see. Dali, Dali. Thank you very much, Verne, for that inspirational song, the song of hope amidst struggle. My name is Dio Marsolino and I will be reading from the Old Testament. Eglisiastes chapter four, verses nine to twelve, entitled The Value of a Friend. Two are better than one because they have a good reward for their toil. For if they fall, one will lift up the other, but woe to one who is alone and falls and does not have another to help. Again, if two lights together they keep warm, but how can one keep warm alone? And though one might prevail against another, two will withstand one. A three-fold cord is not quickly broken. May God have the blessing to the reading of this holy scripture. Thank you, Diva. Thank you for reading the scripture. Good day. Good morning to those in the Philippines. I've noticed in the chat and good evening to those in Eastern Canada. I'm calling in from Western Canada and Vancouver, British Columbia. My name is Reverend Murray Prudin, Executive Minister for Indigenous Ministries and Justice for the NIA Church of Canada, and Danse. I am Nihil Cree from Treaty Six Territory from North Central Alberta, from the Good Fish Lake Salt Lake First Nations, and the reflection from that scripture reading, it says it all in there. I really feel I don't need to explain too much, but more than one is better. How do we make friends? How do we accomplish to live together if we can't support each other? That is the biggest reflections I receive when I first chose the scripture, but I'm going to go a little bit more detail into the message of what is the ongoing hope God gives us and what is the ongoing call to work together. As I sit here with everyone, I also have this, and you probably can't see it too well, but I'll put it against my chest here. This is sweet grass, traditionally from Canada. Sweet grass is one of our medicines that we honour and use, and it was given to us by our great Mother Earth as one of our healing medicines, and we use it and we burn it for smudging for ceremony, and it smells sweet as the name goes, sweet grass, and we braid it. We braid the sweet grass as a reminder that it's our Mother's braid, and that we burn it, the braid to cleanse ourselves. So this is sweet grass. This is what we, one of our medicines we honour here in our territories across this great land, a grass turtle island. Yes, very sweet. I'm going to talk about grass in a minute here, but this grass has been a gift. It's gift from creation, it's gift from the earth, and we're in relationship with the land and with this grass, and we always have to remind ourselves how precious every part of this earth and this land is, and that's one of the reasons we befriend the world and the land and all the elements, but also all the creatures and each other, each nations of people. We're humankind, we're not human different, we're humankind. I want to talk about blades of grass. I'll just tell you a little bit about blades of grass, and I always, I use this in part of a sermon too for a mentor of mine who passed away over the summer in late Reverend Robert Wright, back in my home community, and I had the honour to officiate his funeral, but when I gave this sermon and I'm only going to give a portion of it, it reflects in a way, and I hope it brings some understanding, especially to the scripture reading as well, and to this idea of two are better than one, that more is greater, that we should know if we really want to work together, then in my opinion, we got to be like a blade of grass, because as you know, as each blade of grass grows, life seems to have an influence on how well each blade of grass will grow as it reaches for the sunlight, and if there's too much dry heat, and the blade of will dry out, grasping for moisture, and if there's too much water for a blade of grass to grow, it won't drown, but adapt to a new wetland climate and the soil texture, and if it's too cold, the blade of grass could freeze and break off its stem, and if its roots are planted, rooted well, it will regrow and start its process again to reach for that sunlight in the sky, the elements of our world, influence, guide, teach, and mold each blade of grass every day of its existence, but still at the end of the day, no matter the influence and daily existence of the blade of grass, it's still a blade of grass, like its fellow brothers and sisters around it, so singing and dancing in the wind, a blade of grass. This is the beauty of the world that God has created. It teaches us and relates us to the earthly existence around us, and remember we're only given one world to live in together, and like a blade of grass, we too reach for that sunlight each day, each day we are each a unique individual blade of grass, but at the same time all living and breathing together with a great miracle of life on this earth plane, each striving for the sky, and remember you are love, each one of you a blade of grass, and each day as a blade of grass here on the land, we will remember and live this miracle of life and tell each other's story, that story of reaching for that sky, each one of us a precious and loving creation by God, and when we look at that blade of grass, I'm always brought to this idea of our sweet grass braided, and when you think about our scripture reading as well, if you have three strands together, it's harder to break, and this is why we braid, and are reminded of the story of why we braid our sweet grass too. When you braid it together, it's unbreakable, it's unbreakable, so let me remind you, everyone, all my relations out there, as being a blade of grass, if you braid each other and work together, we're unbreakable, that's what makes us people of the land, that's what makes us nihil, so back to the question beginning, what is ongoing hope God gives us, what is ongoing call to work together? My relations, we are the ongoing hope God gives us, and we are the ongoing call to work together, 20 years of spirited action for justice things, for another 20 years and beyond of spirited action for justice and hope, for generations to come, may God creator bless and keep us humble and always living in a good way as a blade of grass. Thanks be to God. Amen. Thank you very, very much, Mary, for your very powerful message, and as we walk together into the future, we are more than ever aware that the spirit is deep within us and all around us, and we also, as we did, as we began this prayer, we recognize that those who have gone before us are present with us this night. We, the people, pray, and the response to our prayer is compassionate creator, hear our prayer. Creator God, in you we are one. We hold in our hearts those who ignited the spark, which burst into kairos that day in January of 2001, and in a particular way those who have now entered eternal life. We hold in our hearts the many who forged ahead in significant ways these last 20 years. We hold in our hearts those who courageously persist today, and those who will join kairos in the future, and as we mark this pivotal moment, this kairos moment, we relish your love and light, beloved creator, and this evening we pray in thanksgiving for the gift of life that each of us enjoys, and for the lives of our over eight billion sisters and brothers, and all created beings with whom we share the earth, our home. May we be more aware of our oneness, our communion with all humanity and creation, and may the way we live reflect our awareness of our interconnectedness. And as we celebrate 20 years of spirited action, may all of us, staff, partners, volunteers, friends, supporters, and all connected to kairos, continue to be blessed with a heightened awareness of the preciousness of life in all its diversity, and look toward the future with renewed hope. We pray, compassionate creator, hear our prayer, and with hearts overflowing with gratitude, and filled with need, we ask that you grant us the wisdom and the courage to strive to be ever more intentional, ever stronger, ever more trusting, ever more tender and compassionate to one another, ever more tender and compassionate to the most excluded, misunderstood, and unwelcome in our own neighborhoods, and ever more tender and compassionate in our world. And as we do all we can to respond to the communities with whom we work, to our partners, and also to the cries of the world, we pray, compassionate creator, hear our prayer. And so let us take just a moment of silence, being aware of all the unspoken prayers, those that are deep in our hearts and in the hearts of all our sisters and brothers, all our family throughout the world. And we know that Jesus is more than ever aware of our needs even before we are, and he brings them all to our mother, our father. And so we pray, may the blessings of this celebration, that if it has been truly grace-filled, be deeply rooted in our grateful collective heart, and as we walk into the future together, may we dare to hope that we do so in a profound spirit of justice for truth and reconciliation. Amen. And as part of our closing, we're going to hear now from my community, the Nietzsche singers, to close us in a good way. I mean, so the next song we're going to dedicate is a traveling song. A traveling song is dedicated for people who have traveled on to the spirit world and as well giving good vibes all across Canada for traveling and the people in South America or all over the world. We travel with you in spirit and be wet. And now friends, may God bless us with discontent, with easy answers, half truths, superficial relationships so that we may live from deep within our hearts. May God bless us with anger at injustice, oppression, abuse, and exploitation in this world so that we may work for justice, equality and peace. May God bless us with tears to shed for those who suffer from pain, rejection, starvation, and war so that we may reach out our hands to comfort them and to help change their pain to joy. May God bless us with the foolishness to think that we can make a difference in the world so that we may do the things which others tell us cannot be done. If we have courage to accept these blessings, then God will also bless us with happiness because we will know that we have made life better for others with inner peace because we will have worked to secure an outer peace for others with laughter because our hearts will be light and with faithful friends because they will recognize the friend in us. These blessings are ours, not for the asking but for the giving. From one who wants to be our companion, our God who lives and reigns forever and ever. Amen. Well thank you everyone for a great ending to our day. We've walked where we were walking for 10 years, 20 years of spiritual justice and this has been a great thing. Thank you all of you for coming to this service this evening and we look forward to seeing you tomorrow to our final day and our plenary where we will talk about where it is we are going and we're going to be walking in solidarity forward. Thank you. We've had our benediction and our thanks and now we can pretend we've walked out into the lobby. So some of you will slip away quickly and some of you may linger to chat a little bit. That was beautiful. Thank you for that blessing of everything. Bernie, we are glad to see your face. Thank you for your song. You're welcome. Miigwech, Yaman. So nice to see all of you, my God. And Lee, we thank you for your song as well. How many singers were there? Four. Sometimes though people passing through the square would start singing with us. Alison, it was nice to hear those names like Anne O'Brien and Doreen and John. A lovely remembrance. Were there any that we missed that you would want to mention now? Anybody think of someone who's part of the caravans community that we missed? I thought there might be a few names in the chat but you know as the days went on when we had that as we were gathering that list quite a few people contributed and I thought yeah the folks that have been core I think mostly been mentioned. Well folks we go ahead. Thank you for doing that work so we can remember everyone. It was really hard to you know just even as we've been going throughout all the work of the past year how hard it is that a lot of our elders have passed. It was striking to me that there were so many more names sort of from 2017 on. Those memories are fresh and those people are very much missed. Yeah I thank you for pulling this all together Shannon. It was beautiful. Little bit of legwork in the background that's all. I guess. So folks we don't need to draw this out either. We're going to meet again tomorrow unless anyone has any anything else you want to say I'm going to close it up. Just wanted to mention oh thank you everyone. This was lovely and I wanted to mention that tomorrow there is a workshop at 8.45 on women's peace and security and land defense. So you're all welcome to that. 8.45 a.m eastern time. So Jeanette you know with your feeling like 5.45. I might have to get the recording for that one. Yeah no problem we're recording it. It's in French but it will be translated. Yeah okay I wanted to thank everyone for all this beautiful service that was put together and for everybody on the steering committee as well and I'm sorry I won't be able to take part tomorrow but my thoughts will be with you and with prayers and thank you to Cairo staff and all the tremendous volunteers across Canada and internationally. Together we are stronger. Thank you. Just like that parade. Blessings.  Thank you Jeanette. Good night all. Good night. Blessings all. Blessings.
