The commander board should lend itself to experimenting with different pointing devices. Current has connectors for a PSP 3000 joystick. It should be easy to create versions that support other pointing devises, like a trackball, a Cirque touchpad or other joysticks.

How To...

...build the keyboard?

Follow the build video. You can find more support under the links here.

...make the cases?

The case files are available on Printables and Thingiverse.

...compile the firmware?

$ cd /path/to/qmk_firmware
$ qmk compile -kb revolt/rev1 -km default
#  It should generate the firmware file
$ stat ./revolt_rev1_default.uf2

...flash the firmware?

1. Unplug the commander board
2. Push the bootsel button on the RP2040
3. While having the button pushed in, connect the commander board to the computer

A virtual drive (?) for the rpi should be discovered by the computer. Drag the compiled firmware file into it. RPi will reboot and run the firmware.

FAQ

Why do you hate Sofle/Lily58/Corne?

I don’t! They’re beautiful keyboards, designed with love and forethought, all of them with passionate communities. They just don’t fit the criteria of what I’m looking for in an ergonomic keyboard that can be used just as easily for programming and gaming, especially for people coming from “regular” keyboards. I wanted to make a keyboard that’s perfect for me and other like-minded people.

No wireless version?

I’m not ruling out a wireless version in the future. I’d like to perfect the wired version to my liking and see what kinds of compromises make sense.

But with Revolt being open source, there’s no reason for anyone interested not to take a crack at it themselves.

Workflow

1. Build matrix, outline and pcb in yml
2. generate kicad pcb
3. Create the kicad project
4. Replace the kicad pcb file with the generated one
5. Replace the switch footprints with the ones from keyswitch library
6. Create the matrix schematic by hand, with the diode numbers matching the swich numbers from pcb
7. change the diode numbers in the pcb to line up with the switch numbers in the pcbnew

• this can be automated together with the switch numbers, I think

7. Add hierarchical net names
8. Update the schematic from the pcb band the other way until stuff is consistent.
9. ...
10. Draw the rest of the owl
