Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

CH552-44 powered by FAK Firmware (lemmy.world)

I saw the FAK firmware that @semickolon wrote / shared here, and thought it'd be fun to try to write firmware for.

Nickel is one of these "JSON + functions" languages.

I found it pretty fun to write declarations for the keymaps. I've shared my code at https://github.com/rgoulter/fak but here are some things I thought were neat:

Using multiline strings to declare the alphas layer (and then mapping this to keycodes) is very tidy: in ncl/layouts.ncl
Supporting different layouts for a keyboard, e.g. ncl/keyboards/rgoulter/ch552-44/layouts.ncl, so the CH552-44 can have a split 3x5-3 keymap.
Using tap-dance to allow for 'tap'/'home row mods' alphas, e.g. ncl/keymaps/ch552-48/default/keymap.ncl

The PCB design files (and other useful files, like plate files, 3DP case files, etc.) can be found at https://github.com/rgoulter/keyboard-labs (there's also a design which uses the CH552T directly).

I thought it might fall into the non-split ortholinear category, but that makes sense once you pointed it out.
