Idan of holykeebs.com released a new variant of foostan's classic Corne – with a thumb trackball, replacing the outer thumb key.

Continuing my appreciation for trackballs, I modified the Corne PCB to take the Pimoroni trackball instead of the right most thumb key, while keeping the same footprint as the other Cornes – Idan.

The trackball can be installed either above or below the PCB. Above puts it closer to the keycaps' plane, below (as shown in the photo above) is more aesthetic when installed with a top plate.

Resources

• The PCB is on github,
• or you can buy it fully assembled at holykeebs (don't forget the KBDNEWS discount code for 5% off).
