Show HN: Elytra – A 420g CNC aluminum, wireless split keyboard

I've always loved ergonomic split keyboards, but I hated the desk clutter. Most splits on the market either require that annoying TRRS bridge cable between the two halves, or if they are wireless, they are often housed in bulky 3D-printed or plastic cases.

I wanted something that felt premium like a custom mechanical keyboard but was light enough to throw in a backpack. So, I built the Elytra.

A few technical details:

Truly Wireless: No cables between the halves or to the computer.

Material: CNC-machined aluminum chassis. We used a biomimetic design on the underside to shave off weight without losing structural integrity.

Weight: It weighs only 420g (0.93 lbs), which is weirdly light for a full-metal board.

Firmware: Powered by ZMK.

I would love to hear your feedback on the layout, the industrial design, or any questions about the manufacturing process. Happy to answer anything!
