RESONANCE EFFECTS FOR EVERYONE TO SHARE

[gotoluc]

Have you tried an air variable across the secondary, like I showed in that video? By varying the capacitance you will vary the resonant frequency of the coil...It works frighteningly well for me.
I have no problem lighting up a NE-2 neon bulb with just one lead connected to the coil and another to me--that must mean at least 90 volts. And I can produce a continuous spark across inside this little transient spark gap thingie I found today...by fine-tuning the secondary with a variable capacitor...without even having the second lead hooked up !?!

The thing about flipped polarity DC vs. chopped DC will depend on your capacitance and frequency. At some frequencies there isn't much difference. At others the flipped polarity DC will act like AC (which it really is) and the chopped DC will act like AC with a DC offset (which it really is.)
Coils, by the process of induction, will generally always smooth out an inductive impulse to a sine wave response. But a square wave or pulse in the primary, with as short a rise time as possible, will produce the best inductive response in the secondary. The secondary's response will be sinusoidal even when the primary is pulsed with a square wave or rapid-rise pulse.
Usually.

Hi TinselKoala,

thanks for all the information. I do have a couple of 4pf variable caps that I use to fine tune my primary.  I'll give those a try on the secondary.

Thanks for sharing

Luc, it's really good to see you continue experimenting.  I wanted to ask you were did you get that o-scope kit for the laptop, I would like to get one.  Thanks Luc

@Wattsup,

Luc asked me to look into a circuit that used the 4013 and IRF640 because he had those components.
When I designed that circuit I relalized that I needed two high side drivers to get it to work. I desided to
use the IR2103 since I already have used the IR2103 and knew that IC. The data sheet for the IR2103
states that one should use a decoupling capacitor on both the low side switching (at the input of the IC)
and at the high side of the switching. These capacitors will help average the current going to the IC so that
the wires and other parts stay cold. The 100 nano Farad capacitor on the high side will help to reduce
heat in the diode. The IR2103 is designed to operate at up to 600 volt on the high floating side. The IC is
also tolerant to negative transient voltage and dV/dt immune. The hexfets used has internal diodes between
drain and source and will survive voltages up to the rated voltage for the types used. But you know Luc. He
immediately cranked his variable transformer up to 50 volt and ran the circuit. LOL

The back emf voltage pulses from the coil is brutal at this voltage level. He was operating the circuit very close
to the maximal voltage level permitted by the components used because of the  back emf voltage spikes.
Luckily for us, Luc did not know that. The circuit barely held together and he found the new "effect" in his output coils.
Then he found that the initially used diode (1N4007) was warm when running the circuit. It is my best guess that some
of the back emf voltage was "burned" away as heat in this diode and when we change it to a faster type then the voltage
spikes had nowhere to go. The hexfets internal diodes was not fast enough to channel the back emf voltage back
to the power source so something had to give in at some point in the testing. The IR2103 was the one that couldn't
take it because of over voltage so the little IC just caved in and burnt the high side internal mosfet transistor. Then Chris31
chipped in and suggested a change in the design that will keep the IR2103 safe. I added the components he suggested
but has not tested the new circuit. There you go, now you know why this circuit is designed the way it turned out to be.

Now we has designed a new switch based on what we learned about the old circuit. I do not know if the new circuits
will be better or worse than the old one because I have never tried to run a coil as a load at these high voltage levels
before. I understand that we need transistors with a high voltage capability etc. The new design uses "floating" switches
that are powered directly from the high voltage side of the circuit. But, knowing Luc, he will probably crank up the
input voltage to 100 volt and just vaporize the transistors and opto couplers. LOL

That said, this is a good thing. Without Luc's testing we will never know what it takes to make a good circuit that
can survive the high voltages and also display the "effect" he discovered. So we are on a road of testing and designing
good circuits that can do the job and still work another day. I think that if we work together will will archive that goal.

I all in for P-Type mosfets and other circuit solutions. Anybody that has good ideas if free to design circuits solutions
and post them here. Please do a drawing of your deviation circuit and post it here. Your design may be very good and
can be the next circuit we build.

Now I would like to address a "phenomena" still floating around on free energy forums. People like to group other
people. I often hear words like EE's and OU's. I do not like it at all. In here we are a bunch of people working for
a common goal. There is no "us" or "them". We are all just peoples doing the best we can to develop something
that may work some day to help solve the energy problem once and for all. I can only look at myself as an example.
I started out my working career as a fisher man. Then I completed three years at college and was educated as an
radio and TV repair man. This is the only school years for me. I have played with electronics as a hobby since I was
approx. 9 years old. Now at 51, I have studied many books and try to keep up with the changing world as best as I can.
Does this makes me an EE? Yes and no. But in any case, I have had great fun with electronics as a hobby and for
the last 5 years also researching free energy circuits. I think is is the fun that keep me going.

Groundloop.

@ Groundloop & Gotoluc

Man you guys are the best  and definitely stand apart from the crowd in my books!!! 

When it comes to OU and fooling around with circuits your creativity and Gotoluc's sense of adventure are showing us all what it takes to have a thick skin and keep experimenting   Thanks a bunch!!!

I still hold hope in the coming new year that there is a chance that maybe someday soon some of us will achieve our goals of OU through the school of hard knocks    Screw the books and established laws, laws are meant to be pushed and broken anyways 

Keep picking at it 

PS:  You guys remind me of Scotty in StrarTreck...."I'm giving it all she's got Captain!!!"...take care and Happy New Year folks 

Regards,
Paul
