It's a good what the hell, am enjoying this ! And here you go Jim, some results While we don't know the wire up of TinMan's creation I took some liberties. Biggest liberty was to wind it bifilar...32AWG and 28AWG. 30 turns, single layer x 2 directions. End of 1 of the 28AWG to the other winding direction start 28AWG. Both of those go to positive power input. The other ends go to transistor Base and Collector. Then one of the 32AWG's from positive power to the Base of the 2N3904 transistor. A 100ohm resistor is in series before both wires get to the Base. It will work with no resistor, but drew 150mA. Now, it's much lower at around 70mA, which is still too high - but here are the features: Runs well on a 1.5V AAA Uses only a transistor and the cube (resistor for lower current) It self starts Has wireless output The spare 32AWG wire can run a green LED brightly off the pickup energy. Sorry about the dirty hands, ferrite isn't very clean stuff when it's been under the hammer.
