AC from Joule Thief Secondary/pick-up

[nueview]

hi Jeanna

i like your data very much as it seems to follow some other threads data as well.
almost as if ground cuurent is a sink lowering voltage much like flow does for water hammer.
current flow restriction seems to make the circuit more active as far as pressure is concerned possibly allowing current to be derived inwardly toward the wire from its surroundings in order to light your LED while also raising the frequency time base.

Thanks bill,

I thought that was it, but it is not. This neon site starts with most of the components we don't use, like mains power etc.

edit
I found what I need.

I plunked in .38inch and 208khz and 26 gauge wire
I am wanting to find resonance with 208kHz because That is what I have. It is coming up in many readings from the other secondary.
I think it is where to start making each segment or what comes off of each secondary powerful

This may be its most powerful place.
I will see.
I have everything I just need to wind it.

This is what the calculator tells mw for a radio receiver that is cylindrical in form...
Here is where he is:

thank you,

This could be a good tool.  Thanks for the good find Jeanna

Ha,
It works, well, something works
I will make a drawing to show you all.

I removed one of the S2 wires entirely; and the other wire I split into a Y. I put one of each end onto either side of the 3 leds. The inductor is still attached to the middle one and the S1.

The lights are more dim than with both ends of the wire on the outside ends of the leds, but not much. I suspect I just need to find the right inductor.

I noticed that touching the loose S2 wire brightened the leds a bit so I clipped an aligator clip to it and dropped it to the floor.

The scope could not see a difference between the ends of the Y so reported no volts.

There is more to do here and i think it will be fruitful. I think I need to find a cap that is in range.
The frequency between one of the ends of the Y and something else, maybe the S1, is 100KHz without the new inductor and 200KHz passing through it. I am not too sure about the connections, but you get the idea.
I will do more and something here is working.

edit
At the end of the day I made a drawing for you.
I am showing where this Y is and how it is connected to the rest of things and I must say the light in this part of the circuit can get brighter at no cost to the brightness of the other lights. I think this is going to be important.
I hope someone with experience with inductors and caps matching can help here. I am in way over my head. BUT I do know there is something here.

Hi everybody,

I am making a kind of progress here.
I am lighting 4 leds in series on the S2 and all the 10 leds are staying on without change in S1.

I tried adding one more (a second) inductor yesterday. It worked really well.
This is just like the pic above, but with 1 more inductor of the same value.

I read about mutual inductance where the inductance of 1 inductor will mess with the next if they are too close together, so, I kept these apart.

That was with the other wire from the S2 unattached straight up in the air.

It also works with that other wire at the inductor end of the string of 3 leds.

Now, today I added a 4th led to the string of leds .
Predictably the lights went dim.
I added one more (a third) inductor in series. It didn't help much.
Then I added the free end of the secondary S2 to the third inductor end of the string.

The lights got brighter.
I do not think they are all the same brightness and they are not as bright as the other S1 string of leds, but they are almost as bright.

Then I measured volts across points in this S2 circuit.
It is good voltage; higher than with 3 leds and 2 inductors.
I will draw that later, so for now, there is a little more progress.
Inductors are very helpful. I wish I had a bigger supply.

I cannot find any help so far using a cap.

This is looking a lot like Tesla's so called hairpin set of lights. I just learned that name yesterday.

What  you read about  mutual inductance  is probably one of those half truths  that  is  used to   keep people from  findng  OU

Did  it say that the  best way to deal with it is by keeping  the inductors far enough apart?

Doesn't  it make sense that if the  field from one inductor  can mess with  the field  of another inductor in a negative way .....isn;t   it likely that  it can also mess with it in a positive way ?
I bet   they didn't mention that .
In my  opinion  this  is  a good example  of  how  what  is taught  has been tweeked . 
The  truth  about  mutual induction  is there is more to it  that  our schools  are teaching .
