galvanic cell output

(1/2) > >>

chemicalLindsay:
I know this may not be all chemistry but in the galvanic cell that I have constructed I get an average output of about 0.3 volts and a range between 2-16 milliamperes.Does anyone have any ideas of how I could get such a small output to run a relay or switch a circuit (I have tried using a transformer but it didn't seem to work however I might be using the wrong transformer,please help).

billnotgatez:
It is my impression that transformers typically use AC rather than DC.
Try constructing a solenoid that uses less electricity.

Donaldson Tan:
You can always re-construct the original Daniel Cell

Corvettaholic:
you're getting DC output from your cell, you need to convert it to AC which is a lot harder than going the other way around. radioshack should sell some IC's that'll let you pulse it "good enough" for it to work in a transformer.

chemicalLindsay:
I don't know where to buy it from radio shack but couldn't I just use a bridge rectifier (diode)
