This is an octagonal LED matrix made of 213 LEDs. It features sand and PIC/FLIP fluid simulations, Conway’s Game of Life, and several interactive demos. Each LED can be dimmed from 0 to 100% in 1% steps using a logarithmic brightness curve that matches human perception.
Its main components are an STM32G441 microcontroller and a BMI323 IMU. The LEDs are driven by an IS31FL3763 matrix driver.
Everyone knows the slightly annoying Simon game. I made a very simple one around 20 years ago (here). I’ve now made a new one that adds several "annoyances" to the game.
