Conductive Paint is a conductive material made up of a conductive powder suspended in a binding fluid. When dried the conductive powders will be close enough together that the material itself becomes conductive. There are different kinds of Conductive Paints, but the easiest and cheapest to produce utilizes graphite powder. Carbon Graphite is a surprisingly good conductor and is both easy to come by (as it is often used as a lubricant) and relatively easy to work with and mix into other materials.

Picture of the materials I used. Acetone, Graphite, Liquid Tape
Total Cost: If you have a container, some paintbrushes and scrap wood you can get by for under $20.
This is a very rough process because I did not have anything to measure with.
Note: For this batch I used a lot of liquid tape and slowly added more graphite and continuously tested this mixture
REMEMBER: Do this in a well ventilated area!
|Trial 1||Trial 2||Trial 3||Trial 4||Trial 5|
|Overload||284.1 kOhm/in.||14.4 kOhm/in.||5 kOhm/in.||1 kOhm/in.|
The different trials are the same mix with more graphite added. Not a whole lot of measurement was taken, but as a proof of concept this was very effective.
