Slayer's AA battery core.
Slayer hit the "Jackpot" with his solar light 1.5 AA, but "Lidmotor" couldn't get his to work. AA permeability is a hit and miss proposition. Inductance is an indicator of permeability; The higher the inductance the higher the permeability.
The "Flyback output" of Slayer's Joule Thief is more a function of coil inductance and core permeability then input. Selecting a high perm AA battery by testing, then winding a fat coil around it like Slayer did, should be able to push the simple AA LED magnet oscillator over unity with little problem.
The mechanical oscillator can have a springy portion of the bulgy coil left over on one end to oscillate from the magnet underneath.
