This is really not out of the realm of a dedicated hobbyist.
The switches and keycaps can be ordered from quite a few vendors.
Also, custom circuitboards are no longer difficult to design or produce in small quantities (especially separate left/right boards).
Use a Teensy to wire it together as a USB HUD device.

- eltoozero 8y agoYou mean USB HID, Human Interface Device.
- kimdotcom 8y agoYes. Good catch.
- metalliqaz 8y agoShameless plug for my own custom keyboard firmware project: https://github.com/dhowland/EasyAVR https://github.com/dhowland/EasyAVR Works with the Teensy
- justwalt 8y agoThanks for linking this, I’m actually in the design phase of this project right now so the timing couldn’t be better. I’m going to try it some time this week.
