BOM and documentation for the Orca Livecoding Environment Terminal: a tiny computer built from off-the-shelf components made to run orca-c (https://github.com/hundredrabbits/Orca-c). The current design is intended to fit inside a eurorack modular synthesizer, but a standalone design would be possible using a small enclosure with breakout ports.
Future goals include designing a simple interface board that breaks out MIDI from UART on the Raspberry Pi, and eventually a custom design that breaks away from the Raspberry Pi entirely. It's most likely that this would involve using a Microchip SAM9X60 or similar microprocessor running a custom linux distro built with Yocto or Buildroot.
