Kapanadze Cousin - DALLY FREE ENERGY

[mihai.isteniuc]

I did short out both L1 and L2 one by one with a short (3 cm) wire. but nothing changed (was measuring gate and drain signals)

A lot of atention should be gived to ringing filters. After I have connected L1 (from main Dally's coil) at the resonance of L2-C, the ring back it's so strong (at least in my case), that it's interfering with the pulses coming from VCO-NANOPULSER. The effect it's so strong that it's triggering the mosfet-driver and later the mosfet transistor even if I stop the VCO. The high voltage pulses are then generated with the frequency used for L1. I don't think this is OK

It can be that your high voltage probe is widening the pulse. Anyway dv/dt seems to be the important parameter. What is the rise time of your pulse? (not the width)
In my experiments I had a bigger voltage by adding a second 1N5408 in parallel. Also, your output capacitor is 9nF, per your video. Try to reduce it.

Hi Black_Bird, 

yes, could be that that HV probe interferes with the shape.
I am presently working on this ringing problem, so removed the DSRD, but will measure the rise time lateron.
Concerning the 9nF cap., i did this (moved from 1nF) because "exnihiloest" has some good results with a 10nF cap., see this forum thread:

But i can return to 1nF any second.

editted: i checked the HV probe specifications and it mentions a rise time of less then 7ns, so my 20ns probably are real.

Actually the rise time of the probe will somewhat add to the real pulse rise time. In a rough calculation you can subtract 14 ns ( 7 ns rise time and 7 ns fall time). I would say your pulse is about 6 ns width.

did you try putting the diodes in series? i'm looking back at gotoluc's thread:
URGENT! WATER AS FUEL DISCOVERY FOR EVER

here is a post from that thread that, i think, gets pretty close to explaining what we are trying to achieve.

thanks.

If the gate signal stubbornly rings at 30MHz despite being grounded by the MOSFET Driver (pin 3 of U1) via the 4.7Ω resistor (R2), because the internal capacitance and inductance of the MOSFET are responsible for it (and cannot be eliminated), then this stubborn oscillation still can be selectively blocked by an LC tank circuit composed of C3 and L3 and inserted between pin 3 and gate of Q1, as shown below.

To block 30MHz the C3 could be 220pF and L3 could be 128nH (9x 3mm loops of 0,8mm wire in air).
..or any L and C combination that satisfies the equation 1/( 2*π*(L*C)^0.5 ) = 30MHz

P.S.
According to this calculator, 9 turns of 0.8mm wire wound over a 3mm cylindrical former will form a 7mm long air-solenoid, that will have the inductance of 128nH.
