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:

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).

That doesn't look very ergonomic

[–] rgoulter@lemmy.world 5 points 11 months ago

Sure.

One of the neat things about mechanical keyboards (broadly) is that there are all sorts of avenues for creativity that people find interesting. Some people are enthusiastic about making their keyboard look good, or sound good. Some people like designing PCBs.

I saw the FAK firmware was quite constrained.. it's well suited to small keyboards, and it's got a low cost microcontroller. I'm sharing here about an example of a keyboard designed to use that, and some of the firmware using that. I figured some people here might find it useful or interesting.

For the keyboard in the image posted, there are different decisions which could be made which could perhaps improve comfort. Different decisions would come with different advantages and costs.

It might not be "hand-shaped", but the use of layers (and tap-dance/home-row mods) will minimize hand-movement, which is another way to approach ergonomics.

[–] rgoulter@lemmy.world 3 points 11 months ago

Yeah, minimizing hand movement, and reducing use of the pinky fingers, and letting the thumbs use at least 2-3 keys each are all things that improve comfort.

It only fulfills point 4 I think, but it does look like it might not be in line with the rules on the sidebar, so it will probably get removed (admittedly I don't know if posts need to be manually approved here, so I'm not sure about this).

[–] hisbaan@lemm.ee 2 points 11 months ago (1 children)

It's technically a unibody split (notice that t and y are 2u apart) so that qualifies it as ergonomic according to the sidebar if I'm interpreting it correctly

[–] unmoored@awful.systems 2 points 11 months ago

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