Tin of joules

Just a poor mans joule thief.

It's some nice creative work.

I don't see how this qualifies as being an overunity device. Joule thieves don't output more power than they consume.

Where exactly was there a claim of it being an OU device?

A JT put's out the same amount of power/energy as it consumes -it is a unity device.

some can come very close to unity,
but in general, JT's are poorly made, with little consideration to their functionality.
and thus are rather inefficient.

I would expect some large inductive losses with the tin can, as well as poor (low) frequency response, and wasted field

that being said, nice job. This demonstrates that with some scrap parts and a little ingenuity a JT circuit can be built out of anything.
