[Show Lemmy] I got tired of TRRS cables, so I built a 420g CNC aluminum, truly wireless split keyboard (lemmy.world)

Hey Fediverse,

I’ve been a long-time fan of split keyboards, but I always hated two things: the annoying bridge cables (TRRS) between the halves, and the bulky 3D-printed/acrylic cases if you wanted to go wireless.

I wanted a clean, zero-cable desk setup but with the premium feel of a custom CNC mechanical board. So, I spent the last few months developing this project: Elytra.

Here are the specs I managed to hit:

100% Truly Wireless: Powered by ZMK. No wires to the PC, no wires between the halves.

Ultralight CNC Aluminum: To keep it travel-friendly, we applied a biomimetic cutout design on the underside. The whole full-metal chassis weighs only 420g (0.93 lbs).

Low Profile: Designed for better posture without needing massive wrist rests.

I just got the website up and running for early pre-orders: https://elimkeys.com/

I'm currently working with my manufacturing partner to refine the hardware tolerances and tweaking the ZMK firmware. Since this community knows ergonomic boards better than anyone, I would absolutely love your raw feedback on the layout, design, or any questions about the manufacturing process.

Cheers!

Wow, looks awesome! Although I'm more of a columnar stagger kind of guy (and handwiring), I can appreciate the amount of work you must've put into this!

Do you have a plastic cutout around the antenna, or how do you prevent isolation by aluminum?

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
