Interesting idea and product.
Did you measure the resistivity?
I just borrowed an analog Radio Shack 17-range multimeter indefinitely from an acquaintance. And I also went out and bought some of the necessary supplies: "steel" reinforced epoxy glue(resistance=30 giga-ohms (!), regular epoxy glue, white school glue---and for a metallic resistance-reducing source, a cut-up aluminum pie plate( really small pieces). I can also use really short multi-strand twisted copper or steel wire of a small gauge that's been wire-cut to about 1/64". (Available at a local hardware store.) For graphite, I'll go cheap and burn either paper book matches to carbon ashes, or do the same with wooden strike-anywhere matches. (This stuff won't be pure graphite, but it's cheap enough (read: pennies) to be good for a starter prototype material. Will try and get started next week after the Fourth. --Lee Reedit, 5 Jul '11: Text edit for visual clarity; main paragraph.
