My MFC design (330mV peak voltage)
This design was very easy and I would like to thank Paul Nylund for helping me understanding the concept and guiding me. :)
I have used the most easily available stuff in this which you have at your place.
The normal voltage was 280mV and it went till 330mV when aquarium pump was turned on.
Will design a better MFC in future which could light up a LED :)
