I was sitting on my computer when a strange whim struck me, and I took out some batteries, my (crappy) DMM, and the Single Sided Arduino PCB I have printed out on regular paper (with my injet) for fun. I attached the wires and touched a trace with my DMM, and to my surprise, it showed voltage!
This led to the printing of an accurately labeled line and more testing.
Using a combined total of 14.88 combined battery power (one 9V is dying
), I discovered:
By placing the + end of the batteries at the 0" mark, and attaching my - DMM lead to the - Battery lead, and the + lead to the 1" spot on the line, the voltage dropped to 2.68 volts (about a 82% drop :O).
But after that initial drop, the voltage only decreases at about 40% each inch.
I know that sounds like a LOT of resistance, but I wasn't expecting this to do anything at all
. Any clue what in the Ink is causing this phenomenon?
