By some stroke of luck, you've made your way here. The Ploopy Trackball. For left-handed people. Your life will never be the same.
This repository contains all of the design and production files necessary to make a Ploopy Trackball. For left-handed people. We've also included some kick-ass documentation in the Wiki on how to get it made, assemble it, and program it. (It's the same as our documentation for our right-handed trackball. You can find it here.)
What are you waiting for? Your new life awaits.
Did I mention that this is for left-handed people? Because HELL YEAH, it is.
If you're looking for a hex file containing working QMK code with a keymapping compatible with VIA, look in the firmware directory.
Note that the schematics are the same as the right-handed version of this mouse, so the revision number will say RX.XXX, not LX.XXX. This is intentional: the mice are schematically identical, and only the layout of the PCBs is different.
The firmware is released under GPLv3. The hardware is released under OHL CERN v1.2. Check the respective directories for full license text.
