@jeanna,

I got the latest toroid to work, however, placing a tertiary coil on the toroid yields no results - no lighting of an LED of a freely wound coil.  At any rate, this particular coil isn't boosting voltage very well at all and it's drawing 32ma just to light a LED - so it's a no go.

But I'll keep trying.  The way my toroids are wound is primary coil is counter clockwise with secondary wound top-over and in and back around with an over-all direction being clockwise.  Magnetic fields are at 90 degrees to one another - so, generally speaking, they're probably half as efficient as they could be.

The 2 wires must be wound together to work, not one over the top.

Heres my latest video of 2xAA running a 40Watt Neon Tube with a hand wound core. It has 30 turns for the 2 JT coils and a 3rd coil with 530 turns

now that is what i called crushing deep into ground. 

how long does it currently take you to fill those caps ?

[innovation_station]

sorry bro that was not my work but i intend to do this... 

i dont expect it will take long to charge them but im thinking 100 v is my limit ... as this is what my rings put out constant ...

i dont want the caps to compound .... meaning i want them to fill to there value at most then i will drain them ...

i do not want to keep filling the caps to the point of overfull  ...  so far i see with the mk2 it will only charge the caps ..  to the value of the output ...   

i in the past have been able to over charge big caps with ease ....   i hear they make a big boom when the go off  cuz they were over charged ...

lets get rid of this problem .... 

ist!!

i will be chargeing cam caps today ...

from dead aa batteries...

@ dodoshlodo

Thanks for your videos. Can you provide any information on the current flow from the battery for the large fluorescent tube? Will the tube light from 1.5 volts? What is the diameter of your toroid? Your seem to be getting performance similar to slayer007 with only one transistor - great work.
