This project is a wearable animated wristband featuring 11x WS2812 LEDs stacked on top of a silicone band. The design uses 3D-printed elements—11 glowing sections that tightly fit around each LED to hold it in place, alternated with 12 black spacer elements for clean separation and visual contrast.

At its core, the wristband is powered by an ATtiny85, a compact microcontroller capable of enough compute power to do audio sampling and LED animations. A slim 220mAh battery keeps the design lightweight and portable, making it perfect for adding a splash of color to any raver outfit.
