The maintainer circuit.

A form of a joule thief that powers a led light, that shines on a solar cell that is used to recharge the joule thief`s battery. http://www.youtube.com/watch?v=ZrhH3zlOJCM

Hi,

I have done a similar test but with a bigger pannel and a JT powering a neon tube recovered from a laptop screen.That light was enough to keep it in self running and have light at the same time.

Kool,,I was thinking I was the first to have been down this road, goes to show,,someone else always has..

Great. How did you modified original circuit of solar garden lamp ?

[pese]

why this can work?
a solar panel have have 10 % efficency (the best 14%). . The Led will not lightning the fully surface of panel = lost.

If you contruct tha its full lightning. so the light is weaker, and  it hve lost that light  go also outsides of panel.

also the j.t. converter produces losts !!

it is i,possibel to contruct THIS WAY an electronic-optical (light) PERPETUUM.

Only nice experiments to learn the physics.
