Building a Joule Thief

Documentation

Bacterial battery : Electricity can be founded even from bacteria in mud. At the beginning, the volume of the electricity from bacteria was not that high and not that stable (It was almost only 0.012). But as time goes by, it became higher. About 3weeks later i measured the volume of the electricity again and it was about 0.2 and quiet stable. And still it is alive! :) Even a month later, it still alive and I can measure the electricity. :)
