AC from Joule Thief Secondary/pick-up

[nievesoliveras]

@jesus,
...
1- There is a regular joule thief with a basic joule thief light (bjtl)
2- There are 2 secondaries wound on the basic toroid
     2a- one of them lights up to 3 leds in series
     2b-one of them has many turns and feeds its AC volts into a breadboard, which I called the second tier.
3-There is a toroid on the second tier breadboard which is wound like a bjt with a secondary.It has a pirmary bifilar and a secondary of many turns. These are basically acting like inductors here.

What confuses me is the Led marked as D.
If the circuit I made is correct with the tiers connections, then this Led will be working with the AA battery voltage only.
That is it is connected between the positive and negative of the AA battery.

Maybe you can make an effort and check if the connections are correct and clarify that detail for us.

Hi jesus,
Oh, now I understand your circuit with "D".

Maybe this will help,
Both the legs of "D" are in the battery rail of the second tier.
But
only one wire from the secondary of the first tier(red wire) is in the neg rail of the second tier.
There is one other wire in that negative rail. It is a wire from the neg side of the light "C"

The other leg of the "D" is in the pos of the battery rail
The only other connection to that is the center tap of the bifilar of that toroid inductor.

If I put the 2 red wires into the battery rail of this breadboard the effect is weak. It is ac.
It is not a dc circuit and only a little of its energy can be used.

It makes a very weak joule thief battery, because it is ac.

That is the reason I am trying to make the circuit diagram from tesla's light experiments work with the 2 tier.

I will see if I can move some lines around on your drawing. It may work.

My eyes are tired today and it may take a little more than today to straighten this out. I am grateful to you for your help.

edit
here is a trial at a mod of your schematic.

Thank you Lady @jeanna

I noticed that you put the battery positive to the side instead of in the center tap of the BJT.
You left the center tap unconnected.
Is it like that the way you have yours?

oops
The first tier is all that on the left side and it is just a regular jt with a secondary.

the center tap is in the normal way.

The center tap on the second tier is only attached to the pos side of the "D" light.
If I reverse that light it and one or 2 others go out. It is strongly polarized.

I probably made other mistakes too. Please let me know what else.


thanks,

Thank you Lady @jeanna !

I will make some changes for your consideration as soon as I can.
