I will try it again, now I get it about the secondary led.

Remember, most of the time when there is a REALLY HUGE blizzard, it is preceded by a hot spell, because the cold air (from wilby's storm) is moving in a sine wave and pushing tropical air in front of it.
When I lived in Boston, I kept a down jacket and mits in the trunk for those strange surprises.
So, Little A might be smiling tomorrow yet...

kooler just gave me an idea, I'm gonna try now...

this is how i lit my 1st cfl... very bright.. bifi A
wth.. it post the same pic twice..sheeeeessssh

No kooler, it is the same. 142v from 14T secondary either way. Well, the look of it might be better... like higher frequency, but hard to say.
Thanks for the clear pic, too!

I guess as xee2 said, it is mostly the number of turns and the permeability of the toroid that determines the output from the secondary.

What made the tower of power different is the fact that it is in resonance... and stays there.
It is also a series inductor added to the secondary.
I have yet to devise a way to check out that part of it in any other way.

thanks for the idea.

@all

I have a question , what if we used the led to lower the voltage from the secondary , Will it raise the miliamp output from the pickup coil.

Like converting static pulse into steady output ?

Any idea? ...

I know i did not sleep last night ...

@ all
i ordered me some more different types of scrs and sidacs the other day.. the reason i haven't showed you guys what i been doing is i took a pretty big shock... 120 from the wall feels better than this,
it burned thru my skin on my fingers but i was pushing 3 volts at 60ma's thru it...
luckly it blew a scr.. cause i could not let go..
just goes to show that being carefull isn't enough.. one hand in your pocket still seems to creep out and touch the circuit somehow some times..
so i do not advise anyone to build my circuit and try to go big with it.. after the third stage it gets to f***ing dangerous
i had no ideal that a 450 uf cap held so much power at 327 volts
once i regain nerve you will see more videos

thanks
