Abstract
The invention comprises a variable linear resistor. It comprises a first plate having a recessed area cut into one face and a second plate parallel to and facing the face of the first plate with the recessed area. A length of elastic tubing is disposed in the recessed area. The distance between the two plates is adjustable, and this allows for the compression of the elastic tube.
