The Anouk Kitty Ears Remix
I remixed a headband that contained a light up solder kit developed by Anouk Wipprecht. I loved the cat ear headband design but wanted to develop PCBs with an audio visualizer circuit. The left ear PCB contains the microcontroller and power circuitry and the right ear is responsible for capturing audio data from 7 different frequency bands.
Here is the github page that contains the project files: https://github.com/ADataDate/AudioReactiveHeadBand
