Dear all,
I'm actually a biologist/chemist by trade and have built a DC fuel cell for demonstrations that can generate about 0.5 V and 25 mA. At the moment we wire this to a multimeter to show a current, but I'd like to use something else. I know there are 2 mA LEDs out there but I need a way to boost the voltage without resorting to building new cells or quickly rewiring capacitors from parallel to series. I hear there are joule thieves that might do this but the parts seem very difficult to find.
Any suggestions about what I might do with this (other than bin it) would be fantastic!
