... That's a 200:1 voltage ratio.

Interesting Hazens,

Most of mine seem to be about 100 times more than expected. Did you see what the factor was with just one 2^o coil?  If it is also around 100 , that would at least reflect some of my findings.

And maybe I can see a pattern?

Thank you,

a pic i circled the diffrent things YOU SEE IN IT....

the 2 vert boxes are the 1.4khz pulse ....   the   oval is a combining wave ....   a result of the 2 no?   and the big square the spikes.... 


if im wrong please do explain ....


ist!

The two vertical boxes, I agree.
The big square, probably just noise. I honestly don't think it's anything special.
The oval wave. I think you got me there. Could just be some residual wave from removing power or it could actually be something else. Not exactly sure on that one but is there enough of it there as far as voltage is concerned. Don't even have the foggiest idea how you would be able to capture the little bugger to use it for something??
Any ideas?

mr maggs ... 

perhaps i shall drive my ass there and teach you in person lol 

sure we can use every part of this 

lol

i honestly think the oval is a result dirrectly from mixing 2 freqs  now we add a neo to amp it     

and you got my  ist cap charger ..... 

come on guys ....

its not hard  it was hard as hell to figure this out backward .... lol 

ist!

When I just had the single pickup coil 7-7-70 and was getting 250 volts from 1.3v input thats about 192:1 and the 7-7-70-70 with 1.3 in was getting 350 volts, that's 269:1. I bet if I add a 3rd pickup coil the ratio will hit over 300:1 output from input. The numbers do not add up to normal transformer theory. I would expect 13 volts from the 7-7-70 coil with a 1.3 volt input. These ratios are at least 10 times higher than I would have thought.

IST,

You are more than welcome to come here with your coil. I would love to put it on my scope.
Maybe we could teach each other something.
Looking forward to your visit.
