I really liked your article on solar power. I'm trying something with another 'clean' energy source at the moment, the dynamo. I've been Googling around and getting bits of info from here and there, but I still don't get the whole picture.
The one thing that really stumps me is the whole one wire thing coming out of the dynamo. I've been used to + and - things and now this has threw my brain into confusion. I've seen some dynamo circuits and they seem to have 2 outputs doing stuff. I just don't get it.
Any chance you could do something along the lines of how to get the current from dynamos to work with your circuits? And with pictures! Thanks!

What type of "dynamo" do you want to use? The term is somewhat ambiguous in its meaning.

oh sorry, that would be an oldish bike dynamo like this: http://upload.wikimedia.org/wikipedia/commons/5/58/Bicycle_dynamo.jpg

Oh wait, I have read stuff from that site. Thats the one that screwed with my tiny brain. Well there is some stuff I haven't read from it yet, but most of it I came directly to, from google.

Try building their basic LED headlight. It's a straightforward design and I'm not sure that I'd do it any differently.
