Qromatech Bow

Technology by itself can only get you so far. Integrating technology with artistic expression is part of what makes us human. Doing it at scale is what makes us a society.

High school orchestra performance of Lullaby for the Moon using Qroma.dev to accentuate performance with light up violin, viola, cello, and bass bows.

Collaborating with the local high school student body/orchestra at scale (over 50 bows made!) is what got this from a workbench prototype to a "this can actually be a thing". It was super fun collaborating with the teachers and students (teaching them to fish) so that we could go from my lab to the stage.

At this point, students are fully able to assemble/solder their own ESP32 and custom PCB boards, attach them to WS2812 light strips, and configure the light displays via the (Qromatech website)[https://www.qromatech.com/content/software/make-your-own-qromatech].

Technologies applied:​

  • KiCAD (for custom PCB design)
  • ESP32 (for bow controllers)
  • C++/FreeRTOS/FastLED (for controller software)
  • React/Typescript (for web-based flashing and configuration)
