On your sheet of paper, outline the shape that you want your mixer to take. When designing your shape, keep in mind the path the signal will have to take from source to speaker. The shape shown is great for four-channel mixing.

Fill in the shape with a graphite pencil. Make sure to press hard and apply several layers. The graphite must be thick enough and continuous in order to carry an electrical current.

Cool proof of concept! I can't see how this would be useful in any practical circumstances, but it's definitely an interesting idea. I didn't know that graphite was conductive!
