assignment: do some preparation on the final project

final project preparation

what?
well, i was still thinking of making my hammock holder that would be remote controlled and all that good stuffi talked about here. but then, my good friend dimitris papanikolaou suggested that i should really do something with the microbial fuel cell i was working on this week.
so then i thought, why not make a huge christmas tree, have some lights on it, maybe sensor controlled, and have those lights be powered by the soil in the pot around the tree?

oh, i think i will make my hammock holder anyway.

how?
get lots of carbon cloth (or some kind of carbon anode- better if naturally found), aluminum chicken mesh (or another cathode), soil, water, make a circuit and then power the leds. i will probably have to make smaller cells and connect all in series to be able to power the leds.
i will create/get/use a voltage booster. i actually already ordered a free sample from texas instruments here and it seems like i would have to make mine.
