Dec [{(
)}]Another fantastic and impressive Mitxela hardware project.
The Fluid Simulation Pendant contains 216 green LEDs, arranged in an octagon and diagonally charlieplexed, displaying a realtime fluid simulation using DMA on a 100MHz ARM Cortex-M4 STM32L432KC with 64KB of RAM, and an ultra-low power accelerometer for motion input (and wake-up from the idle and power-off modes).
It's all powered by a rechargeable 2450 coin cell underneath the PCB.

"It's no secret that LEDs can work as light sensors, the main problem is that they're just not very good at it."
Alex WillmerProgramming an LED matrix wirelessly by flashing a screen at the LEDs, and using them as light sensors. No Bluetooth, no WiFi, no camera, no audio. A GIF would suffice. https://www.youtube.com/watch?v=IHD3ji-F600 https://mitxela.com/projects/lightcomm #Mitxela

The smallest and silliest MIDI synth yet
Ben Brooks π¨βπ»π§π»This week I also built the excellent Precision Clock by #mitxela
It took about 3 hours, and my rusty soldering skills got a bit of a refresher. Thankfully improving with each one of the 299 through-hole solder joints (plus redoing ~5 cold joints)
Now I have a millisecond accurate GPS-powered ISO timestamp on my desk, and the girlfriend is not in the slightest bit impressed by this.
