<\/a><\/p>\nMy first test uses\u00a0activated carbon from an aquarium filter ground in a coffee grinder. I mixed this with melted pine resin. The resin starts to liquify with a small amount of heat. A hair dryer will cause it to bubble. I mixed in the carbon dust and spread the hot mixture on a stainless steel mesh.<\/p>\n
The result was an electrode with too high of a resistance. Somewhere in the neighborhood of 25KOhms between the surface of the mix and the steel mesh.<\/p>\n I then found mixing full carbon granules into the pine sap resulted in a lower resistance. I went ahead and tested several mixtures of pine sap and carbon. I also tried some graphite dust mixed with the sap, and two commercial carbon based paints applied to steel mesh as well. Here are the two products:<\/p>\n http:\/\/www.amazon.com\/MG-Chemicals-Conductive-Coating-Aerosol\/dp\/B008OA931A<\/a><\/p>\n http:\/\/www.amazon.com\/Keypad-Restore-Conductivity-Carbon-Copper\/dp\/B0026PRMVM<\/a><\/p>\n I tested each electrodes resistance by pressing them down onto a copper plate wired to one side of my multimeter, and wired the other side to the stainless steel mesh in each sample. I took care to make sure the mesh did not contact the copper plate directly.<\/p>\n The large granules mixed with the pine sap seem to perform pretty well. My next step is to build an electrode with a larger surface area in order to increase the voltage and current output.\u00a0I might try building the water container entirely out of the carbon electrode. I also want to try and eliminate the steel mesh. Im not sure if\u00a0the resistance is low enough across\u00a0mixture to just attach a lead on one side without an added conductive plane.<\/p>\n","protected":false},"excerpt":{"rendered":" This week I began testing mixtures of carbon and the pine resin: My first test uses\u00a0activated carbon from an aquarium filter ground in a coffee grinder.
