Joule thief Circuit ...... "Joule thief" is a nickname for a minimalist self-oscillating voltage booster that is small, low-cost, and easy-to-build; typically used for driving light loads. It can use nearly all of the energy in a single-cell electric battery, even far below the voltage where other circuits consider the battery fully discharged (or "dead"). Hence the name suggests the notion that the circuit is stealing energy or "Joules" from the source. The term is a pun on the expression…

Very cool chair from a log! Another example that there is a lot of talent and imagination out there. I sure hope the video boom doesn't stifle this kind of imagination.

That is so cool! You have to know how to move the blocks to open the box :O
