Bill B. : The short term indications of this circuit are two-fold, being able to drain the battery down to the very bottom, getting your moneys worth, and draining
your batteries down to ensure that they are all re-charged equally, without a 'memory', adding longevity to rechargeable batteries ! The circuit seems to work in
a manner similar to a super capacitor saving up the charge up to the excitation threshold and 'pulsing the power to the light. This actually happens several times
a second and the rate of the 'flash' can be very accurately controlled with a small change to a standard 'Joule thief circuit' !
This 'flash' actually happens ,we don't see it because our mind tricks us with 'Light memory', the joule thief just shows us the amount of light we actually 'need'
to see - though of course it can't tell. While batteries, C.F.L.s, and L.E.D.s last longer there is a question about incandescents !

Yup, as far as i can tell, it is upping the current, to replace the voltage.
This is why joule thiefs can run an led down at .5 volts.
The ringer is little different color of cat.
I think the transistors act like the cap, but by cascading thru the coil, you get a feedback loop going, and can use smaller voltages to power larger drains.
Lookup "flyback transformers" for the circuit used in Tv's and such.
This seems to be more like a transformer cascade. An old trick of hooking up a bunch of transistors in series, to get a current amplification going. Tends to blow up the transistors though.
The coil seems to collapse the field and smooth out the spike.
I'm still not sure why it runs so long, tho i can understand how it would work for a few seconds or minutes.
