@xee2

Hey what type of wire are you using on that toroid? And where did you purchase it? Can it be found online?

Thanks!

Can you post plans of your self runner? I have been wanting to make one with a cap in place of the battery and can not seem to get it to work.

Thanks!

xee2,
Yes, mine too. I suppose if I did it properly with clips it would work better. The leads were meant for a car etc. I should solder some wires to the ends.

I only prepared 3 composite pictures.
They say on them what they are.
The last one shows the problem very well. I made an extra set of marks over and under the next wave so you are sure that it is that far away from the other two.
The frequency variation between the close pair and the more distant pair is 11.1Hz and 2.22KHz pretty big difference. also the voltage range on that one is 17v-225v. If it lights a neon, it will light a fluoro, so I guess it does not matter... but in case it does, it is nice to know how to make a pickup with a nicer wave.

This is the replication of the circuit you just posted 2T10T20T. The wave on 20T is very much like the one included here. The pic did not turn out so well.

85 degrees!

Awesome work jeanna.

-Altrez Hi . It was off topic but does use the basic components posted at one magnet bedini started by jonnydavro !It uses My basic idea of feeding back to the source from a secondary with caps and rectifier .check it out , I know it can be replaced with some maps instead of a magnet i bet .

There posted in one magnet bedini started by jonnydavro . No i dont have the link handy .

Do you happen to have a link to that post

@Altrez, thanks. It was interesting to see how ugly a wave could still produce the ability to light a neon.

@xee2, I am trying to understand why you thought my pics were reversed. (they were not) Maybe it is just a resolution thing.
I was at a higher resolution on one than the other and the waves look longer, but that is because the screen changed resolutions.
At every resolution except 2MHz or close,  the wave is made of 2 digital lines. One up and one back. I believe it is skinnier than it is shown and therefore the frequency actually does change, but in less than i pixel width. Only at that very high resolution can I see the wave spread into a 4 pixel width triangle wave. (I cannot say which resolution because I cannot get 2 spikes to appear on the screen at the same time when so close.)

@Gadget,
I am glad to see you here again.
You did something very novel a way back and got 1600 volts added to an output. I am finding that this is what ac circuits are all about. I know you do things intuitively so you may not know the answer... no problem if that is so, but, I want to know how you grab the right capacitor to match a particular inductor?

I have been looking online and I will continue to, but you seem to be able to do this already, and I wonder if you can help me.

Of course anybody else can help too!
Gary said I was looking for impedance matching. I need to look that up.
EDIT: impedance matching appears to be overly complicated. I think I just need to find the inductance value and its matching capacitance.

thank you,

jeanna
