[simpits-tech] Potentiometers

[Rod Dale]

An easy way to use linear motion on a rotary pot is to fix the body so it 
can't move, connect the shaft to the chuck of a cheap carpenter's hand 
drill (as if fitting a drill bit) then connect your operating arm to the 
handle of the drill (the piece you turn to operate the drill). The arm can 
be moved almost 180 degrees while the pot shaft will turn it's full 270 
degrees or whatever it is rated at. Depending on the gearing of the drill, 
you may not need to move the arm very far to get full rotation of the pot.
