Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

"I am afraid to say that I have Joule Thiefs that do much better than that and use a lot fewer components."



yes, you opened the toilets doors in the bank. there is no money.

hi,

Thanks for your useless comment which serve no valuable purpose in this forum at all. :P

Until akula thread will be fixed I will just leave my reply to this thread:

wattsup:
"@T-1000 just posted that the resonance has to reach the cores resonance (simply put) to have some "nuclear" effect. But how the hell do you except to achieve anything of that level if your circuit is locked at 300KHz. Something is wrong with the values."

T-1000:
"In this case the LC resonance frequency must match ferrite natural resonance frequency or its harmonics."

for example: if you have yours transformers ferrite resonance 2.23 Mhz, you could reach the core resonance excitation with coils resonance on 22.3 Khz or 223 Khz

The best hit is on 1/2 1/4 and 1/8 of material resonant frequency. If you are going to build it and have proper ferrite core - you will see... :)

By the way... current draw is 110 mA at 3.0 V and when I pull the power it takes the LEDs about 4 seconds to fade out completely.

hi,

What about adding 100nf capacitor in parallel with 100uf capacitor to smooth the ripples in the sine wave.
1n5819 may not able to handle 80volt...90volt spikes since it's design up to 40volts.
maybe UF4004 would fare better.

I wonder if the insulating mica sheet would convert radiation into electrical pulses which produce ou."Just theory"

yes,   I'm not right in details, but I understand how it works.

This is one of the standard ways of determining resonance in a coil/core. What part is the "ferro" part and what part is just ordinary electrical LCR resonance?


::)
I also think, that akula can use LC resonance but he can think, that it is feroresonance. But if he not make mistake, then if you change number of turns on secondary coil and primary, you must find same frenquency were amplitude rise. That frenquency is feroresonance.  :D
