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. :)


Question : when the mud dried out, will the bacteria also die??


Joule Thief : Just followed the instruction and at the first time it didn't work. But with help of one of students I could copy the structure of the breadboard which is perfectly working and I got succeed to light it up. Through this experiment I know basic knowledge of breadboards.


Simple nutritional medium(workshop) : By mixing agar, malt extract and distilled water we can culture almost any sorts of mushrooms.
