New Jewel Thief "Resonate LCR Circuit" Much less energy draw....

[pese]

pls use at first transistor only an small signal transistor
that will normally used for 1-100ma currents.

NOT ANY power transistor wil work properly
in the avove circuits, because hiher leackage currents,
and no any "gain amplifation" is testet or garanteed at such smal base currents that are used in this circuit.  the gain can degressed daramtacally lorer from (exampel) 50 @ 1 Amp..
it can be  2 @ 1mA !!

NOT ANY CICUIT that have workes (such way) at the "inventor"
must work, wuth your components wit same types of semiconductor - (This was 40 jears my job, to work and develop such
cicuits - so pleas give attention to select your components for
fine application in "The working applications voaltages amperages (conditions)  and power .

xee2,
    What did the darlington do as far as additional load on the circuit?  Is there some way to add the jt function back into this circuit? I found a much clearer JT illustration, attached, if that will help. Is the JThieving actually the bemf biasing/amping through the NPN, goosing the AA bat?

In this circuit, the light is produced as a result of the oscillation in the inductor when the resistor is connected to the base; the voltage gained is converted to light - this boost only serves to overcome the voltage necessary to produce light.

During the time when the transistor is off, the voltage increases and a path from positive to negative is created with higher than original voltage potentials.

Over all, i think the LED to be watt-volt oriented, when current can be substantially, yet proportionally cut back to a minimum.  The idea would be to use same wattage or less, but higher voltage - because voltage is easier to boost than current.

Don't know if it helps, but I replicated the Joule Thief from the schemata on the very first page of this topic. Works really good . I had no 100pf capacitor, therefore I took a 6,8 nF. 1 winding was not enough then, and I found out the more windings I used the better the result was. 200-450 windings on thin wire showed a nice glowing LED .
Since the Joule Thief works with Voltage peaks from the collapsing magnetic field only, I wonder if it would be possible to catch these 'Overunity' peaks otherwise and send it somewhere else...? (Maybe feed the battery again?...)

xee2,

  The primary bemf is not being fed back through and amped like the orig jt.  That's what makes it a JT.  It's not going to add load to the circuit, cause it's bemf.  Your meter may show higher load, but it's BEMF, and so it's not coming from the battery.  That's a real brain teaser....

Here is my version of Chilliqueen's circuit.
I added a 10Kv trigger transformer for the inductor and removed the capacitor.
Then I added one of DR Stiffler's towers to the base of the pnp transistor.

Here is the video.
