 What does this pay down this is the fruit show and tell this is the best place to show off You're awesome. You've printed wearables electronic PCBs or retro tech Anything is game here. I'm gonna take a couple minutes to check out everybody's awesome projects. I'm gonna start off with Sherry Haas Hello, Sherry. Hey, hi guys. How you doing? What's it doing? How are you? excellent We're just a couple days out can make your music festival and everyone's working really hard and Glad to be previewing it here on show and tell What I can tell I don't know if you guys want to ask me questions or you want me to go Okay, so what everyone should know this is a free event It is the world's largest gathering of makers in a really cool a cool space an imaginary place online It's a campus that will be of 15 buildings Each building will have nine to 20 makers in there and you can see in the windows We'll go in there in a second you can check in the windows and see that you'll be able to play the building learn a little bit About more about the makers eight of the buildings have been curated by really cool groups like acoustic out of the UK Bella, you know, probably the Bella platform board makey-makey dog bodic We have Stanford CCRMA where they're doing really cool things We have San Francisco Center for New Music that have really great great things and people like Bart Hopkins and Sudu and David Ramis and they'll there's even some Fred Frith pieces in there We have the French. They have two buildings. Go figure Make me France. There's a lot of makers over there and we have Kevin Lau from China So Asia Pacific makers, so we've got it covered Each one of the buildings when well, maybe you could go into the the presentations second schedule Oh In the schedule we have two days of live programming from 6 a.m. Pacific to about three thirty four Four o'clock Pacific time Saturday and Sunday the links will be at the top there There's a link that you can click click on to get kind of a gridded schedule and then below you'll see everything else We also have a cool project in Mozilla hubs by our friends at acoustic and eclectic With some of their folks have curated a two-hour experience, so you'll want to check that out as well Now we can go to the building and I'll chat a little bit more as we head back to the building in addition to presentations Performances and workshops. We have five workshops Mitch Altman is going to be doing live from Berlin an hour Learn the solder workshop. So if you know anyone that wants to learn how to solder There's no one better to learn from than Mitch. Yeah, create your own personal soundtrack workshop We have a build Lego switches to To trigger your makey-makey workshop We've got a tinkering with sound automata workshop and a jack trip workshop, and that one is coming out of CCRMA That'll be at three thirty Pacific time on Saturday That's for folks that want to figure out and use the jack trip software to jam online together So that one's gonna want to miss and I'll let you guys this is you know, you can cruise around the building Check out the front door Yeah, I really love the way that they're presenting all these videos all the demos Yeah, so there's a video about there's there's something for it with each maker There's a connect area to with all of their social This one I don't have has it and there's actually if they have a patreon or buy me a coffee Just like life you can like throw them some change When you when you go over the building actually it's sort of like playing the building You can get a sound cue for what the sound is like behind the window and the maker 15 of these buildings to start with nice Yeah, it's like in a couple of them. I think I like like the voice changer the prison bell and the the synth Trampoline is so cool. Yeah, and we'll have judge. We have judges actually John Park for me We have the stem chat Women Natalie Z drew and Diana anger judges. We've got Dan the drummer from okay go who's a judge we have tosa from may what thank you to judge We've got you know it goes on and on it's a really great thing There's no reason why everyone shouldn't go this weekend and the best part and then I'll let I'll let everyone else go The best part is it's free and we're gonna keep on adding to it It's a it's a it's a city of imaginary buildings, and you know real estate is cheap. So Going and I Were actually for school and education and as you can see each one of the buildings is named after an experimental Music pioneer this one's Oram. There's a cage building a Siani building a pheromone building Building a Laveris building so a little bit of education as well Very cool. Excellent. As you said, I think you mentioned that this is gonna live even after the events over So yeah everybody mark this it's so cool, and we'll be popping up periodically with with a medicine one throughout the year. So Yeah, yeah Thank you so much for sharing Thank you Go to John sense knows a little bit about that. All right, let's open John. Hey John. Hey guys. Yeah I'm super looking forward to that. I'll be getting access I think on Friday to start going through them all so I can Hand out some blue ribbons maker fair style, which is It's been a while so thanks for that sherry. It's it's gonna be a real treat to check things out So I just wanted to show off a little gizmo. I built if you can add my camera There you go. I showed this on my new product pick stream. These are these really cool little rotary encoder breakouts that use a Seesaw chip so in this case, it's a Sam do 9 but it essentially makes an intelligent encoder And we I think the more has been planning a bunch of these where we're gonna have Little breakouts that are intelligent and run over I squared C So it's essentially like having two microcontrollers each of these has a teeny little microcontroller that is handling Only the pins that are needed for something like this rotary encoder and this neopixel So they each have a little underlit neopixel for feedback and these certain these happen to be Push encoders so you can click a button on them But this is a really nice way to prototype stuff. That's a little Beakier than just sticking them on a breadboard and and you get a little more Flexibility with it. I happen to put it in a row But you can put them in it, you know make a cube of them if you want you can put them on a screen Just thinking yeah, in fact if I just bend my very thin three print there you go. There's my And then in this case, this is some of our demo software For the guy that just came out that is running on arduino with this little OLED So you can just see those values showing up as you use them and we have circuit python libraries in the works and Python libraries in the works. So that's kind of a Just a demo of it, but I am as you may have noticed I've got this hooked up to my little MIDI feather wing out that has a couple of Key switches on it. So I'm planning on doing some some sort of MIDI CC controller Actually, which will be fun Yeah, go ahead. No, I'm just saying how awesome I can't wait The one thing I want to do is tease tomorrow on my workshop show I'm gonna bring this little guy out if you if you've never seen one of these This is a funky little soft potentiometer. So I'm gonna be showing that during the circuit python parsec So Four o'clock Eastern time. Awesome. Thanks a lot John. All right John. We'll see you tomorrow. Yeah All right next up Jeff Jeff. All right, we're checking with Jeff. Here we go. Hello there So we were talking about what is available on what circuit python boards recently And we realized there was something missing which was the RGB matrix on ESP 32 s2 So that's what I've been working on and I got it going today This will be going into version 7 when it's ready, but yeah Just adapting some code that Phil B wrote and is work that already works in Arduino and bringing it over into circuit python Which is kind of RMO when it comes to the RG matrix. So look for that in a couple of weeks There are a few bugs left to chase, but that's what I've been working on Very cool. So good progress. Thanks a lot. Sure. All right. Yeah, we're good one. Thanks, Jeff Let's see what is he'll be doing. Okay. Hey Phil B. We'll check in with you That's cool. I'm looking forward to the matrix stuff. Anyway When the RP 24 the the pie Pico board came out designed this this reference card for it because the pins aren't labeled and This took days to do because like you make typos and stuff. You got to run up by it Hey, can you proofread this and kept screwing up? But eventually happened after multiple days. So The more has been working on the software to become a team effort I've helped and Kathy's been helping and stuff and if you go to the screen share this software it Partially Automates the process of making these sort of pin references and there's still a lot of manual assembly That that has to take place to produce one of these But rather than taking like several days to make one reference Will like I did two of these in a day and this is just wow ramping up, you know, like like Launching rockets, you know, the first one explodes on the pad But after a few tries you stick the landing and We'll be able to crank these out fairly quickly I think but Beautiful Yeah, the the colors were all very carefully chosen and yeah, please mention that these are Color people have like color blindness like it's friendly to all those like the palette. Yeah They won't see the same colors But at least you won't get to that that they're always distinct You won't have two categories that look the same to some folks. Yeah So that's that's what we got going on So I'm like, yeah, that's eye candy I Yeah, these are just bitmaps right now, but we'll have them in PDF format. So they're like printable super super crisp and everything poster size Awesome, thanks so much. Well, yeah, thanks for sharing. All right. See you Melissa. Okay, Melissa. We'll call on you next Hello. Hey, hello So I have I'm gonna do this old school here. I'm just gonna tilt my Thank you. All schools good. Yeah So I have my setup here and I have a little water level sensor here and I have the bowl tilted so it's out of the water. So it says add water so if I go ahead and tilt it so that It's in the water Okay, now it says low and then if I tilt it a little bit more It's a spool so It kind of can be a little bit slow and updating because the sensor has some water on it and One thing I did is you can actually hold down the button here and it'll show you the raw value that it's reading with the analog so I'm gonna use that for helping to calibrate it and I'm working on a guide for that and that will be published soon So then the cool thing about this is Originally Lamar was saying that it can only detect like if it's wet or not But you're you were able to figure out a third away. Yeah, you can probably do the even more like a percentage if you wanted to but I Have found this to be very accurate at least Okay, I'll definitely use this to stick it on my water heater After the recent leak it we need this All right. Thanks Melissa. Thank you so much. Thanks. So all right next up. We will check in with Dan All right, then you got your Hey, Dan. Hello So I was gonna talk about Dynamic USB descriptors for a circuit Python, which is something that's coming up in circuit Python 7 And the idea is in circuit Python up to now you've been able It presents various USB devices and you but you haven't been able to turn those on and off at runtime You can make a custom build that says like well, don't show me circuit pi or don't show me The keyboard HID keyboard or don't show me the repel But you can't haven't been able to like write a program to turn those things on and off and so you had to Like make a custom build or if you wanted to have a special kind of gamepad or joystick or something So what we've got now in circuit Python 7 and it's in the latest builds and It'll be in the beta whatever in the alpha that's coming up Is that you can at runtime in the boot.py file you can turn on and off Various devices so you could turn on and off circuit pi. You can turn on and off showing the repel Channel and also you can turn on and off a separate Cereal channel that you can use to transmit data to another Comports say on your windows box like that MIDI on and off and You can also define custom HID devices at runtime in boot.py So if you have a special joystick or something that to match your particular Device like a foot pedal for your airplane simulator or something that you can do that right away Without having to build a custom version of circuit Python. So what I've got here is this is a typical kind of Yet another rotary encoder. This is a volume control project. I did like several years ago which just got a trinket in it and With a regular rotary encoder and right now if I just turn it you can see it adjust the volume and if I Press it it mutes or not But what I can do I Right right now this the trouble with this thing is that when I first plugged it in it showed circuit pi and it Used up one of the comports. So I always had at least one circuit pi device on my Computer and it was really frustrating. So I had to make a custom build to turn those things off And then I couldn't change the program without replacing circuit Python again loading a new uf2 so instead what I see now is that we can have this code you can put in boot.py and here Assuming that the mute button is not pressed use the mute button as a like a special thing then If it's if it's not pressed then I turn off the storage drive Which is circuit pi and I turn off the REPL So there's the only thing that it's presenting is the key is is the volume control stuff and if I wanted to To make it to make those things show up what I'm going to do is I'm just going to hold down this button and Reboot it And now you see the circuit pi drive showed up here So now I can go ahead and edit the program and I don't have to like reload Anything on to this so these are all coming And it's a bunch of different new features and some people have asked for boot keyboards Which are you can talk to your bias and we'll be doing that too. That's not implemented yet But this is all worked out really well, so you can customize the USB devices Some boards have more USB slots than others So it's make sure you choose a board that has enough what are called USB endpoints to turn on as many devices as you want Everybody everybody in the chat room is like this is amazing And yeah, it's gonna be perfect like keyboard projects So we don't have to have you know all the the boot drive or the drives show up So I couldn't hear you because I was muted No, I'm saying that everybody in the chat room is like I always have an issue where I plug in my circuit pie drive and like I have the cura slicer open So that steals the comp or it like it starts giving M commands to my This is gonna be really handy for that. So it's gonna be right everybody and all kinds of people want to build Like building keyboards with pipe ecos is like it seems to be an extremely popular application So this will help support all that so you know some can't wait. Thanks so much, Dan. All right. You're welcome All right, all right Mark oh, no, Liz. Yeah, I was gonna check it with Liz. Hey, Liz. We'll get you Hey, hey, hey, how's it going? I'm working on Kind of an overly complicated solder fume extractor so choosing the fun house and SGP 30 sensor for air quality and then what is this called EMC? 2101 fan controller and so basically the idea is The out of particulate and co2 in the air is going to be directly matched to the PWM for the fan And then that's gonna be right out on the screen here and I'm gonna eventually use Like a 140 millimeter Computer case fan so you have like more fumes being extracted And there's five volts five volt pad on the back of the fun house So I'll be able to get that but if I cover up the sensor Should be able to see the value changing on the fun house. Maybe yeah, it's trying to go up So with that then the PWM goes up on the fan So yeah, it's kind of one more time right now and eventually I also want to have it connect to So then when you have a soldering session, you can see like how much fume was extracted While you were soldering super handy Also, it could be like if it doesn't sense any solder fume to turn off because that's one of the thing I always walk by the solder room and it's just sitting there just Blowing away. I'm like, ah, whoops forgot. I Got like ideas to like make it a nose or something for the face. Very cool Thanks so much. This is awesome. Can't wait Keep showing us progress You too fight fight All right, next thing we're gonna check in with Micah. Hey Micah. We'll come back. Hey. Oh You made it. You made it So hi, I've been working on a Project that I was following your tutorial, but I think it's cool and it's going to lead to some really cool stuff and Especially like Scott if you're watching this, I'm going to try to port circuit Python to the Raspberry Pi 4 like you were suggesting It's gonna be a while, but I'm gonna try it. Yeah, it's based on that. That's awesome Right now I'm working on Kernel development. So if I switch my camera real quick So this is my setup So I've got a Raspberry Pi 4 and an argon 1 case A raspberry an Adafruit GPIO cobbler Because why not? I Haven't gotten SPI working yet, but I do intend to get this RC522 working. It's just a generic generic one Also have this 16 by 2 character LCD that does work I actually didn't reprogram it to say anything interesting, but if I turn it on it'll say rat nose, but I don't know why Um There's gonna blink five times and then it should display Contrast is weird Not sure I'll be able to get it. I'm not sure I'll be able to get it with the backlight, but I can see it All right, well, yeah, that's what I've been working on and I do intend to port All of circuit Python over to it or as much as possible It's gonna be a pretty long time. I still have to learn quite a bit, but I'm up for the challenge. Yeah, it's part of the journey Thanks so much. Yeah, you come back. Yeah, the children's progress. Yeah All right, all right next up. We'll check in with Mark gambler Hello, Mark. Hey so, uh, I decided I didn't wanted to do a fun house project, so Um Camera is really delayed, so I'm gonna stop looking at the screen and maybe I won't throw myself off So I had the house numbers that I developed A few weeks ago and I wanted to control them and I realized the fun house is perfect for it because of the internet Enablements, so now I can just right on the menu choose what I want to do and it will connect right through It's great. It's just the boards all in one. It does everything I need So this thing's perfect and then I hung a temperature sensor off of the side. So Yeah This is excellent This is a great controller for any new pixel projects like I am envisioning this like with our little LED sign in the front This is perfect. Yeah, I'm thinking just hang this by my door and then if I want to Turn it on or off if I know somebody's coming by and it's just more convenient than having to go to Adafruit IO like the The interface on there is great, but I still have to log on go to web page Yeah, this can just be here a lot more faster to physically just touch the button when you're by the door Yeah, I'm curious which board is running the letters. I might have missed that the letters are Numbers, I guess or be around on The feather s2 from unexpected maker So it's also an ESB 32 s2 board The built I love the built-in Wi-Fi. I love looking things up to Wi-Fi and being able to control them so Between the two of these they work great together. I also got one of the Motion sensors which I have now repurposed from this board Just sitting on the numbers board where I'm hoping I can actually use it outside to detect when somebody's walking by and do something All right, awesome Little beeps like little little touches like that really You know, yeah, yeah, it got pressed Thanks. Yeah, I thought at first that would just like annoy me, but No, you just yeah, it adds that little bit Yeah Thanks for a great project. Thanks All right, and then we got a crystal ball crystal ball play us out. Hello and welcome. Oh camera and Hello, my name is crystal ball. Yeah Hey I'm nine years old I'm in Peru and I made a small Arduino UNO TV vegan Well, if you've seen the TV vegan kits, yeah, I wanted to make one a super simple one for a normal Arduino UNO okay, and Well, just turn on the TV turn off the TV I love any TV. Yeah, that's part. That's awesome. It's an old TV Yeah I love it. I always like seeing the TV becoming like moved on to a different classic project. Yeah, I love it Thanks so much for sharing. It's awesome If you have any links or anything you want to share you can drop them in the discord. Yeah And Thank you Bye And I think that's it, right? Yeah. Thank you everybody so much for joining us We'll we'll do the next week Lamar and Phil will be returning and Don't go anywhere because they're gonna be here at 8 p.m Yep, that's gonna share about six minutes. Yeah, so stick by I think they're in the office So definitely student tune in for that. Yeah, and with that we'll see you guys next week. Bye everybody
