For the past few days I’ve been working on a 3-D printable footpedal potentiometer to be used in a guitar pedal. It is a parametric model in FreeCAD. It has a top and bottom that hinge together, with a potentiometer that is coaxial with the hinge so that when the pedal is pressed, the potentiometer is rotated.
This is awesome… can you tell me any more about how it works? (I assume you communicate to a computer?)
