Hamster Mix makes portable Bluetooth midi controllers the size of a hamster. This enables making music in your pocket, on the go, and wire free with any of your favorite music programs.
After constantly dragging large midi controllers with me when I want to make music on the go, I noticed a lack of good portable instruments to make music on the go. I learned the ins and outs of the ESP32 a microcontroller that enabled a direct interface from the board to any Bluetooth device that accepts midi inputs, including smartphones and laptops.
Our first device, Hamster Mix Piano, is open source, and therefore we are providing some of the diagrams we used to build it:
Wiring Diagram - How the board is wired.
Schematics - Board Schematics outlined.
Arduino Library - We use the open source Control Surface library to code the board.
