Score: 5.8/10 (Innovation: 6, Technical: 6, Documentation: 7, Utility: 4)

Reactive-LEDs is a full-stack DIY project for controlling a 3D-printed LED tube over WiFi, featuring custom ESP32-S3 firmware, a TypeScript CLI proxy, and a browser client for live coding performances. It combines 3D printing, hardware assembly, and low-latency WebSocket-to-UDP communication, with a custom realtime path that outperforms WLED at high frame rates.

Target audience: hobbyist developers, live coders, hardware enthusiasts
