A motion-reactive, battery-powered LED staff with 320 addressable LEDs twisted in a double-helix through a lightweight acrylic tube.

C++ firmware running on a Nordic nRF52840-based controller drives animations along the LEDs based on movement. The battery, electronics and grip are integrated into a custom mechanical assembly.

Studio render of the assembled staff lying diagonally on a grey backdrop, its LED helix glowing through a spectrum from violet at the grip to red at the tip.
