This keyboard was meant to pair with my Surface Pro 3 tablet, so the main area of the keyboard is 21 x 30 cm. This is my first hand-wired keyboard. It was fun to make!
This keyboard includes the following features:
* 1-TB SSD
* Trackball
* Recessed thumb keys
* USB hub
* Arcade buttons for thumb keys
* Magnetic attachment to the Surface Pro
Here are my two main layers:
These layers closely match what I use for my Atreus, so it was easy to get used to it. For usability, I really like the palm keys and the recessed thumb keys.
The following picture shows my hand wiring. I used Veroboard stripboard pieces to help hand wire the main key matrix. I'm bad at soldering, so this really helped hold components together. The veroboard worked well with the Matias Alps switches. The horizontal spacing was perfect, and the vertical spacing was close enough. I did have to drill some holes to fit the large switch posts through the veroboard. I used a Teensy++ to allow me enough I/O points to direct wire 15 of the keys.
For more information, see the following links for build information, case files, and QMK firmware.
I'll probably keep this keyboard as is until I see how it works with more practice. In the near term, I need to add feet or some sort of backing. For usability, my main gripe is that I got the mouse button too far from the trackball.
