Very precise Joystick

This project describes a very precise 3D printable mechanical joystick, based on potentiometers. I tried to use existing joysticks in conjunction with my bechele project, that allows to bring puppets and models electrically to life, but I was disappointed about the accuracy of existing joysticks on the market, so I decided to build my own. Ordinary potentiometer based Joysticks use some transmission mechanics to couple the stick movement with the potentiometer rotation. Nearly all designs do this on cost of a slight mechanical inaccuracy, that causes a inconsistency in the relation of the stick position and the resulting potentiometer resistance. Typically moving the stick from differnt directions to the same mechanical point results in slightly different resistance values. The design of this Joystick overcomes these restrictions nearly fully, since only the inaccuracies of the potentiometers themselves define the inconsistency. The accuray will be achieved using the bearings of the po
