Sound Reactive Neopixel Brass Bell Cover
I'm in a radical marching band called Brass Your Heart, and I wanted to make our instruments light up when we play them.

Below is a mostly step by step process for how I made them using: sewable neopixels, conductive thread, snaps, a Gemma M0, and an electret microphone.
