Joule Thief

What I have noticed especially with the maxcaps is as the voltage increases the amperage and decreases as the frequency increases.  What is happening is the maxcaps are sucking up as much amperage as they can before the coil hits maximum voltage.  It then levels off.

?? as the voltage increases the amperage does what?

I think the amperage thing is trickier with AC than we have been led to believe.
We have a system that can fit into the little box of the dc circuit plan.
And that is all we know about it.
I don't know more either, so I cannot explain too much.
I do know, tesla discovered something that we are not using and I am determined (watch out!  ) to learn what it is and how we can use it.

P.S. Is it an x2 style pickup dual sides?  240 seems like a lot! when I'm finished with this biggo it 208x2dual side windings for both pickups.

It is a MK1 style pickup.
I wound 60 up- 60 down- then crossed over the primary and continued 60 up - 60 down.

Remember when finished I had less than I had with only the first 60 turns done.

I had room to tune on that one, though. I have no more room on the 'tesla's rotating magnet' style

How about 'TRM' for a name?

on the tor-23 with the winding as you drew it the other day...

I did a small battery test this morning before I completed taking the winds down.
I just wanted some numbers for possible later comparison so there is no need to share them, BUT
this strange thing is happening.
(- basically I was just watching the dying battery with lights off the pickup and checking for amps draw.)

In checking the amps draw on this circuit with 10 series leds as load off the pickup,
I saw the polarity change to backwards on the battery resistor.
I reversed the leads and the polarity was still backwards.

Once more for clarity:
Across the 10 ohm resistor in series with the pos battery lead, the amperage seems to be going into the battery rather than out of it!
This does not happen unless the resistor is there.
edit: well, how would I know? maybe it is. end edit.
I don't know if it is helping the battery to recover or not.
The battery was however recovering fast while I was doing  the earlier part of the test.

I wonder if anyone else has had a reversal of polarity without any diodes?

@ jeanna

The JT coil does send current back into the battery as high voltage pulses if there is no battery capacitor. However, the net current flow must be out of the battery because that is the only source of energy to power the circuit.

It slowly levels off on what it needs to use/run off the battery/power supply.  It looks to me like after you tune it it tunes itself to be as efficient as possible at what you tuned it too.

I think more needs to be learned o this, it sounds very interesting.

Not me!

P.S. I have been so busy today, I'm not sure if I will be able to wind today.

batteries can reverse polarity if they are over charged on the other thread were they are doing bettery charging a ground is required but you could also pull this charge from the air by using a coil with a longer frequency and a cap with a diode across the cap the circuit will now draw current to the resonating ciol and flow to the circuit as this happens you should see a scalar effect of a cooling of resisters due in part to a balancing of the mmf and emf.
you cannot think about these two as the same they are seperate this is the point tesla tried to make by his domenstrations the more you add to the circuits the more outside influence reacts with the internal circuit thus his obsession with volume.

well i hooked up the second phase jt ... 

made a video ... 

here ya go this demos what happens on the collector and all coils ... 

ist

i will do a 3 phase video at some point this is an un tuned coil ...  so far .. 

im just doing the verry first tests and its coffee time
