Genesis Engineering created a light-up Hatsune Miku costume for a friend attending Miku Expo 2020 in Europe.

Teensy 3.6 was used to drive the WS2812 RGB LEDs in the 3D-printed headset as well as the LEDs, OLED, and TFT in the sleeves. The costume also includes a light up badge and square PLA hair ornaments. According to the creator who shared the behind the scenes of the design process to our forum, the sleeves are modeled after Yamaha DX100 and DX7 keyboards and can play Vocaloid sound samples loaded onto an SD card using Teensy’s audio library.

Genesis Engineering is a company based in Paris that in addition to engineering excellent interactive cosplay also makes laser harps.
