Keyberon grid

A hand wired ortholinear mechanical keyboard with a firmware in pure Rust. The case uses a parametric design allowing to create a grid keyboard of any size. The firmware allows you to customize each key as you wish: A layer change (as the function key), a key combo (as one key for the paste shortcut) or a regular key.

You can build this keyboard yourself quite easily.

The case

The OpenSCad files are a totally parametric design. You can generate a grid of keys of any size by modifying the parameters. It is designed to be as low as possible.

The firmware

The firmware, Keyberon, is written in the rust programming language.

FAQ

I want to use your 3D printed case, but I want to use a rock solid firmware

QMK supports the blue pill board. You may have to search a bit, but it should not be so complicated. See for example the BluePill handwired. Maybe the firmwares from Cannon Keys can also be interesting. If you do any progress on this side, feel free to open a PR to share your experience.

Keyberon, what's that name?

To find new, findable and memorable project names, some persons in the rust community try to mix the name of a city with some keyword related to the project. For example, you have the Tokio project that derive its name from the Japanese capital Tokyo and IO for Input Output, the main subject of this project.

So, I have to find such a name. In the mechanical keyboard community, "keeb" is slang for keyboard. Thus, I searched for a city with the sound [kib], preferably in France as it is the country of origin of the project. I found Quiberon, and thus I named the project Keyberon.

What is this black and white pattern on your keyboard?

I'm fascinated by isomorphic keyboards. Thus, I've searched a bit which vectors can do a great isomorphic keyboard on a 12x5 grid. After some trial and errors, I found that a major third left, and a minor third up is promising. Then, searching for an origin, I found one that do a great symmetry on the home row using the colors of the piano keys.

So, the black keys on the home row are G#, the whites at left of G# are C, and the whites above G# are B, and so on.

My keyboard doesn't (yet) play any music, that's purely aesthetics.

What's the layout

As an old user of the TypeMatrix 2030, the layout is quite close of the layout of the TypeMatrix. I also maximize the use of the thumbs by having shift, space, enter, alt, alt gr, gui and backspace on the thumbs.

You can of course tune the layout as you wish easily.
