Make a Variable Resistor boxes with 1 Million Settings

College physics lab we got to use these variable resistance ‘boxes’. They had two inputs and six dials, and could generate one million different resistances across the two inputs. I knew I had to have one, and why not make it myself? This tutorial demonstrates how to build one for yourself for pretty cheap. Materials: …
