Metro RP2350 take 5 🔄🌟🤞

Sometimes mistakes are made in prototyping; that's why they're prototypes. The error in rev D was funny: while making the QFN80 footprint, the pins got placed clockwise rather than widdershins. Not surprisingly, that board didn't come up at all, so here's a full rip-up and reroute, with the correct pinout this time! Fingers crossed. Hopefully, this is the final revision, and we can move on to other RP2350 boards we have cooking.

more 8:11 pictures on a displayyyyy

tiny update.

if you look closely, in the previous post with the display the picture was rendered a little crookedly and it felt like there was not 1 image, but 2. it annoyed me, and i first looked into the code, and then into the program itself that sent the picture to the board. the solution turned out to be completely different - i just needed to save the bitmap file normally, and not anyhow. i did it with paint, so now everything is fine.

oh, and one more thing. this time i used nano instead of uno, although it seems to me there is no special fundamental difference - the pinout is the same.

Stone Computer

Stone computer is one of my most involved and time-consuming projects I have ever made.

The idea and early sketches first came to me around 2020 when I was thinking about what makes our electronic devices feel different from our other objects. Maybe it's a screen, maybe it's a button, maybe it's nothing but a single blinking light and subtle whirring. Any of these indicators can shift an object's perception from something that could be tossed across a room to something that is delicate and thinking; almost treated as alive. I started considering the smallest change needed to turn a thoughtless, solid object into a device, thereby changing how the viewer perceives and interacts with it.

It wouldn't be until four years later in the summer of 2024 when I was finally in a place to start working on this project for real. I was back in my home state of Rhode Island reconnecting with my friends. The previous summer, we had worked on an ambitious project that included teaching ourselves to anodize aluminum and conducting dangerous experiments in our own backyards. I was inspired by the accomplishment of working on and finishing a project like that just through having a vision and an obsessive work ethic, and I wanted to make something new the next summer.

My friend Cooper and I work well together: I study art and design, he studies electrical and computer engineering, and we share a strange abstract wavelength of thinking. It was the perfect pairing to make the stone computer a reality. We started with sketches designing what we wanted our computer to do. We made prototypes and tests as we went starting with the form made of chicken wire, the exterior sculpted from concrete, and finally inserting the electronic components and coding the machine.

The final piece is an interactive sculpture that generates a combination of odd words fed to the machine by Cooper and myself. Pressing the button flashes an LED indicator light and shows a new cryptic message on the LCD display. The organic shape of the concrete rock and the unique words it spits out give the stone computer a personality.

It is a fun to use and completely non-utilitarian interactive sculpture, and it makes me happy every time I look at it.

I made an output agnostic logging framework for embedded devices that would work on anything as it's written only with standard C++ libs. In theory I could use it for linux or pis, lol. I made it because I kept having to write new handlers for serial, mqtt, uart, then having to like wire them all together without creating dependency loops or other issues - especially because I often work on meshes or online embedded devices that require multiple outputs. Now you just write your handler, tell it what tags to watch, and it'll log according to tag and log level. So you could write a serial debugging log handler when you're first making it. Then when you're done, disable it, and it'll stop outputting - but then later assign the serial debugging log tag to your MQTT handler and get all your debugging serial lines output to MQTT - then just disable it again when you're done. There's still some polish I need to put into it, it has some jank, some bugs, but it's working and neat. it's kind of neat.

Нет - это не гирлянда. Заливаю прошивку в умную розетку. Теперь она настолько умная что держит сайт и больше не дружит с китайскими облаками ( да и вообще с любыми кроме моего собственного)

More custom trackball!

Some more progress on this custom trackball. That's the core "module" for it comprised of the main PCB + ball. Stuff like button clusters and wrist rest will literally be bolted on to that.

The ball itself's also 3D-printed, works better than expected!

TLV320DAC3100 first bops 🔊🎶💃🕺

OK, after many hours spent with Claude on writing a driver for the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/TLV320DAC3100IRHBR/2260591), we finally have it configured using our driver, and playing an MP3 stream on this ESP32. This I2S DAC has a particularly complex PLL and audio-routing system, so it's not one where you can just pipe in I2S data and have it magically play. One nice thing we got working on is the MCLK, which is generated from the BCLK, so it'll work great with anything from an Arduino-compatible to a single-board computer like Raspberry Pi. We're hoping to get the headphone detection working next so that we can turn off the amp when the headphone is plugged in. Also, it should be able to control the volume from the headset buttons. Also, we want to get the internal beep generator going so we can make tones separate from the audio stream for UI notifications.

hiiiii

tested an ips tft display i have since ahh... spring. not so long ago ive got an idea to embody a scene from 8:11, when ryker got splashed with blood at the screen with leon.

its a wip now but i hope i would not be eaten by exams due this week..

heres more photos of display, but now in a dark.

less interesting - while writing the code it turned out that i didnt have the library i needed, which wasn't even in the built-in ide library search. so i went to github, and there it turned out that the library was outdated and in its place there was a new one (since 2020 ig), the version of which was already downloaded. i had to download the archive and upload it to ide to make everything work. also, i need to edit the program a little and clean it from unnecessary #includes, so there is no confusion.. and i also used a breadboard

Skaven warpstone lantern prototype!

Warning: flashing lights

Here's a little Arduino project I've been working on for my Skaven themed LARP group! It's a multifunctional lantern with three different modes, an unstable warp stone powered light, a standard flame lantern and a full bright white light for those late-night toilet runs.

I'm pretty proud of the warpstone effect, I made it so when the light dims the warpstone becomes unstable and starts crackling unpredictability as it tries to restabilize, then eventually once it destabilizes it glows more solidly and more brightly for a time before it fades and destabilizes again.
