Pot Scrubber Battery—Table Model.ASF
This shows my “Pot Scrubber Battery” running a Joule Thief circuit in series with the little pulse motor. The earth battery version is shown first and then I show a table model version that uses the same type copper and galvanized steel scrubbers. A long piece of thin speaker wire connects the earth battery to my work table inside the house. The voltage on the earth battery version has stayed at .54 volts for 24 hours now.
