RESONANCE EFFECTS FOR EVERYONE TO SHARE

[watercellguy]

WOW, this is what I call colaboration. I'm very impressed.

najman100,

Great job on those PCBs, I know you from ionizationx. you also did a board design for that circuit I designed with stevie to drive the 3 primaries on a toroid.

You guys got me motivated to pull out my tesla coils and experiment....

I was playing with another tuning capacitor on my system of Tesla bifilar coils and look what happened:
When it happened I was holding the capacitor and tuning it by hand, and the LED flared up so brightly and suddenly that I nearly crapped my drawers. It was only for a second, then it dimmed. I spent at least half an hour trying to duplicate the event, before I got it under control. I thought, OMG, I really found it, and now I'll never get it back, and I'll spend the rest of my life chasing it, like all those others, and nobody will believe me, and...
And then I found the resonance again.
I knew, obviously, that tuning the coil would have an effect, but this really surprised me.
Oddly, it seems to glow even brighter if the connection to the variable cap is loose.
I need to get a better air variable out of stock, and play with this some more, maybe improve the range and stability.

Good stuff TinselKoala

Resonance is King

Thanks for taking the time to share with a video demo.

>>So, I know you are saying the transistor diode can handle it. For me this is EE talk. The OU talker is saying, hey, I don't want you to >>handle it, I want you to send it back to the source, period, no ifs ands or buts. This is where if both the EE and OU minds can come >>together, I know we will have some great results.

Thank you for posting you thoughts and concerns about the coil(s) back emf generated voltage. I will address this topic for you.
First take a look at the attached drawing. I have snipped out the switch part and also shown the internal diodes that is inside
the transistors. I have added a plus and minus sign at the input of the switch where the battery will be. When I say "handle" the
bemf voltage then this is my bad English for saying I have given it a lot of thoughts on how to take the bemf voltage and put it
back to the input battery instead of wasting it as heat. Also pay attention to the high voltage electrolytic capacitor.

Now let us see what happens when we start pulsing the coil. First we connect the coil to plus and minus one way by closing
two of the transistors. The coil will charge up. It is like compressing a spring. Then we open the two transistors and the coil
will decompress and release its energy. But since the transistors are off now the coil is not loaded and can decompress much
more. This will give a higher voltage than we initially provided to the coil. Where does this voltage go? It has only one path to go
and that is via one top diode and one bottom diode. This will charge up the capacitor (and the connected battery). Now we time
the next transistor switch on (this is the resonant part) in such a way that we only fill up with energy when the coil has bunched
back to a reversed polarity state and has reached its top potential. This way we do not need to fully charge the coil since we just
refill the lost energy. When the transistors open again, then the coil will stretch the other way giving out the high bemf voltage
via the two other diodes and back to the capacitor. Then we repeat the process. The timing of the switch on and switch off
is controlled by the micro controller IC so that there is a small pause between the switching that allow the coil to be totally
disconnected from the capacitor (and battery). This will allow the coil to reach its maximum peak voltage between each pulse.

I hope I have explained this good enough.

@najman100,

WoW, great looking PCB. You have done a very good job. :-)

@TinselKoala,

Great video. :-)

Man OHHHH Man, You don't know how happy your explanation just made me. This is sooooo great. Finally, I think this circuit is going to be just perfect. In the many threads here, your one explanation should be the basis for any future EE circuits when designing other derivatives. THIS IS THE WAY TO DO IT. Tesla must be so proud. Now I can't wait. I got to have one of these. Santa really did pass early this year. Merry OU to all. Ho Ho Ho.
