Step 2: The "Schematic"
For the wire, I used white for hot wires and black for ground. I think this is the convention.
Diagram shows pot from the side opposite the turning part.
Normally circuit diagrams only use one colour for the wire, but I thought it would be helpful to put one colour for hot and one for ground.
The last one is only a theory on how to wire the full wave rectifier onto it - it may not work. If someone finds it doesn't, please put it in the comments. Check them before you try it.
