From the project
This is a prototype around a PCB I sent off to fab in March 2022... that I'm slowly bringing back to life. I'm kind of using it as a springboard for the next thing, whatever that is and whenever it happens!

Very much work-in-progress. License will be MIT like other kits.
- Kicad project - OpenSCAD for scaffolding and keys models - STLs for 3D-printing
- Easy to solder. Only through-hole parts, even if it limits functionality. - Easy to change. Code can be edited with free software and cheap hardware. - Easy to play. No hidden menus, secret key combos, or overloading. One control per one…
