ScyllaBallz - a tractyl Manuform by tenstaana with OLEDs, roller encoders, audio, and per key RGB.

Build gallery:

This is an evolution of the author's DouBallz.

The case is a modified Scylla case by fmcraft (

Since I don’t wanna spend a lot of time handwiring everything, I also got the Scylla electronics kit. The trackball mount I use here is the same design from my Douballz build. Everything fis detachable from the controller using flexstrips, JST and molex connectors.

The controller is an F411 blackpill since all the QMK features used here would not fit in an AtMega32u4. Blackpill carrier board done by RMI-KB, "jumping off from fmcraft’s Elite-C design".

My ortho advised me against thumb trackballs since they promote RSI. These are setup to be finger trackballs – tenstaana.

Firmware is adapted from drashna’s tractyl Manuform code.
