Published December 16, 2022
Creators! Feel free to tip me off about your keyboard related projects to bring them to 100K readers.

If it weren't the name, it would be not so easy to tell at this point that the base for tenstaana's SkyllaBallz was Quentin's Skylla.

Now with the ST7789. Files are in my GitHub (modded flex pcbs, MCU plate, 3d and acrylic files). No build guide yet. Use at your own risk – tenstaana.

Just to make it clear, the trackball is not for the thumb:

Finger trackballing
