This Wearable AMOLED Choker Runs 16 Hours on One 18650 and Renders Its Animations Live
OpenChoker packs a $12 480×480 AMOLED touchscreen, RGB LED strips, and an RP2350 into a leather choker powered by a single 18650 cell — which survived a full 16-hour convention day still reading 3.7 V. With only 16 KiB of RAM against a 450 KiB framebuffer, the animations aren't played back from the SD card; they're generated on the fly at up to 60 FPS.
