Yes, I don't understand because I use the supercaps instead of a battery.  they charge up very quickly and last a long time.  I charge mine from my earth battery/EER set-up.

Nau the supercap is the 1F 5.5v kind. You can see it on the joule thief video #4, I think.

I just stick it in the battery rail and it charges up while I do whatever I am doing... or I wait for 5 seconds, then I pull out the battery and watch what happens.

I do this because there is no battery recovery and I can see which lights are less or more on because they go out at different rates.

It really helps me tell.
There are too many things here that are unusual, and I just do not trust the meters.

It is the kind used for computer memory.
I think $3.50 at one of those places allelectronics, I think.

So... Isn't this cool?
I got 2 more lights on and they are all equally bright, and there is still room for more since the voltage difference is still high enough on both lines.

great find, and I agree with it all.
  I hope everyone views this and realises.

After talking with Gary, I have more confidence about what I am seeing, so I will not hesitate any longer.

For some time, I have not even needed a capacitor to 'tank' the inductors.
In fact I was seeing great results without a cap, but yesterday and today I have been adding caps to the inductors and getting results.
I even added another inductor to S2 and a cap along with it.

Each time I add a led or an inductor I need to readjust the numbers etc of many other elements to keep all the lights even.

(Keeping the lights even is not necessary for use, but it is how I can tell the effect of what I am doing.)

I now have 24 leds at about the same brightness, I think.
I added 4 to S1 and
2 more to S2 dividing equally, but one string needed a larger cap to achieve evenness of brightness.

The voltages went up all around.
the frequency went down in S2, but not in S1.
I guess this must be related to the fact that I am not changing anything in S1 beyond the number of leds?? but maybe that is not the reason...

I tried to write all the important information into the drawing itself, again, but it is getting crowded.
If you have questions, please ask!

Thank you,

jeanna
