Atreus 62
My second hand-wired keyboard is a clone of the Atreus with 62 keys. Building my first hand-wired keyboard was so much fun and I had Zealios V1s lying around, so I built another one.

Layouts⌗
The layout is kind of a hybrid of the layout I use with my Planck with the additional number row. I switched the “thumb keys” back and forth between having space on the 1.5u or the innermost 1u key. I ended up using the 1u as space and the 1.5u as second return and backspace.

The case⌗
Based on a 22mm oak slab, I used my hand-router to make the cutout of ~3mm matching exactly the steel plate and a deeper ~15mm cutout with a 2mm inset of the plate shape, giving it a nice ridge to sit on. Unfortunately, due to the height of the inner cutout, I was not able to add a USB connector, so I had to attach the cable directly. I added an aviator 5-pin connector to have it somewhat detachable.
On the backside there is an additional cutout under the wrist rest for the brass weight of around 750 grams. I glued in seven brass screw sockets and used PCB spacers to attach the plate to the case.
I finished the case by rounding off the edges, sanding the wood up to 320 grit and oiling it.
Wiring⌗
With the curvature of the rows, the wiring looks less clean than the one on the Planck 64. Overall I used the same materials and techniques as on the Planck64. At the bottom I added a magnetic reed switch to reset the board in case I mess up the firmware.
