'Ploopy' is an open source project where you can make your own trackball, which is the only one in the world.
The trackball is an input interface that operates the mouse cursor by moving the built-in ball with your finger instead of moving it like a mouse. There are roughly two types of trackballs, 'type operated with index finger', 'type operated with thumb', and 'type operated with palm', and ' Ploopy ' is an open source project where you can make your own trackball.

All developed in open source, the firmware is GPLv3 , and the hardware part is released on GitHub under the license of CERN OHL v1.2 , so you can make your own trackball.
The problem with trackballs in particular is that most commercial products are made for right-handed people, and left-handed products are quite limited, but even with Ploopy, whose design files are publicly available. For example, it can be used for left-handed people.
Of course, board printing and 3D printing of exterior parts are required, so for those who can not prepare by themselves, kits and maintenance kits that can be assembled by yourself with all parts as a set, and already assembled trackballs are also handled on the official website. It is.
