According to my results the following equation seems to provide the relationship between turns and voltage.
...

Xee2,
That is an interesting hypothesis.
I will check my results against it whenever I make a new wind that resembles another.

I have a hunch that both the way it is wound, and the resonant frequency of the particular toroid might change this a bit, but we will see. I like this.

thank you,

honestly guys do you not think i could dubble up my collector on my last coil ?

meaning do a bifillar wind .. the exact same as i have just done id then be up to 500v in 4 wires..

thease are my expairments today and its like a 3/4 " maybe 7/8

useing a 2n2222 tranny .. 

i think i need to adjust my primary winding ..  for better results .. but im not sure

plus how would i connect  the windings to add up ... ?

this im not sure eather ..

ist!

Good idea jim,
...linux open source maybe someone can add an open source program for the sound cards and the o'scope in linux??

digital oscilloscope
Xoscope is a oscilloscope using input from a
sound card or EsounD and/or a ProbeScope/osziFOX and will soon support
Bitscope hardware. Includes 8 signal displays, variable time scale,
math, memory, measurements, and file save/load.

Web site: http://xoscope.sourceforge.net/

This package is  already in Ubuntu  includet.

Just type "sudo apt-get install xoscope" in a shell

BEAU TI FUL.
Thank you Norbert!

I have a hunch that both the way it is wound, and the resonant frequency of the particular toroid might change this a bit, but we will see. I like this.

The equation assumes that the only thing changing is the number of turns on the pickup coil. The toroid, battery voltage, turns on other coils, etc. must all remain the same.
