Good one to at least try the technique and know about it. You can do the same thing but drive two mosfets.

For your current triple coil, I would try outer and center as left and right since those fields are concentrating towards the center, I would put the collector as the inner coil. Try a slightly lower frequency and a little less volume for the center since it is closer to the inner coil.

Driving the outer coil at a little higher frequency and higher volume will give it about the same timing and strength exerted on the inner coil. You want both fields to exert an almost equal but out of phase influence on the inner coil. But this will ultimately be relative to the actual coils, winds, etc.

There are so many ways of using this method. I know it is limited to 20khz but having two or more frequencies to play with kind of makes up for this limitation.

But in the end, I really just wanted you to know and experience this technique should you need it in the future when you have a special coil in hand and have done all your regular pulsing schemes, this just adds to your arsenal.

Hi wattsup,

thanks for your reply :) and for sharing this technique. I will keep playing with it as I'm now testing longer coils in order to lower coil resonant frequency. I have one now resonating at about 10khz and giving the same output for input energy as the ones I had resonating in the 500khz range. I'll see how low I can bring it. I also found I had to use a ferrite core at these lower frequencies to get a decent output.

Thanks for sharing and please you or anyone else, keep those suggestions coming.

Cant't wait to see some 15 AWG wire around some 12" lenght 4" diameter pvc pipe... or in the other words something much bigger with higher more accountable input and output to avoid parasitic or other questionable low output measurements. Or go for much higher voltage with small awg larger coils. High ohm HV coil should reduce power consumption with higher ouptu/input ratio. Keep it burning gotoluc :)

Hi minde4000,

thanks for your post :)

I already wound 200 feet of 18 AWG on a 4" inch cardboard tube which gives a 9" inches high coil. I have not obtained any better result with it but that does not mean it's not possible to get!.... I just have not found a better way. I also started testing with resonating really long coils but nothing worth sharing yet.

I only worked one day this week on the research. I'm doing some volunteer construction work for a Spiritual Center that I'm part of, so results will be slow for next week also.

Thanks for the positive words ;)

Are you still running it with 12-20v? IF you say output doesnt change if you increase your setup in size physically lets try to increase voltage.  Keep us up to date Luc. Tnx

The way I see it like with one frequency you take up space in mass and with the second frequency you create movement inside the mass depending on how they compliment each other..

Bingo, Dude!

That is exactly why I mentioned the Pancake coil reversal. To show the explanation.

There were 2 swedish high school students that built a conical for a science fair and achieved COP = 11.

Keely: (King of Resonance). This person is a great reference for anyone who believes resonance or mixed frequencies have no power. Did you know that dentists remove plaque with 25khz transmitters?

The two charge models I have seen are : charge a cap up fast and discharge it slow or charge it slow and discharge it fast.

Hi GK,

thanks for your post :)

A YouTube user name: hydro4f3a designed a pancake coil winder and has made many coils and is now testing them. You may want to have a look at his excellent work.

Hi everyone,

just a quick update. I have not dropped the resonance research. It is still going on, I have been away from my lab to help a friend with some home renovations and that is done now.

Here is a scope shot of what my coil is capable of doing at this time, at resonance (see below) the green is the coil output (at no load) and the yellow short peek is the pulse which lasts only 1.6 micro second. As you can see the coil can give many extra kicks under the right conditions.

I know the coils extra pulses will be dampened somewhat once the coil is under load. This is just to show the direction I am working on at this time. Also keep in mind that this is using only the output of a 555 timer and getting this result.

I may need to build a mechanical switch to get the results that I'm hopping for.

Stay tuned.

Luc

Hey gotoluc. I see as time goes on out of some 10 posts per day we dropped to 1 per month...

I just looked at your scope screen. I wonder. What if you would make it as a true LRC so you should achieve a voltage buildup 5x-10x (20x+ under ideal) at least of your initial voltage source if tuned properly and then try to drain that resonnant voltage buildup out with your secondary. I pretty sure you tought about this. Please someone tell me what do you think. All I have is Lawton PWM with square waves scope and mostly everything else you might need but still need sine wave gen.

Hi Luc:
   I have been playing in this arena a bit too lately. I have been reading on the effects
of power factor correction gone bad. That basically meaning what occurs when you
get it wrong by adding caps so it hits a harmonic res with a load. As this happens, you
will see over voltage/ over current on the main lines.
   So what would happen if you purposely load it to make that happen? We all now know
that when you hit res, the input current drops and the curculating current rises. So have
a coil and caps that hit res points 3,5,7 and a way to regulate it to a safe level. One coil
to loop back on its self, say the 7th harmonic and then tap off with the 3rd  and  5th for
your output.
   Grab a cup and sit back and scan through SM's musings and jot down all the references
that could relate to a tuned LC and it will shock you.

Well thats my nickles worth for the hour. See ya.

Hi minde4000, thanks for your post. It may pick-up again but that depends on my results!...people are mostly interested in something that will give them something, so I try to post only the interesting stuff. My research is mostly experimental, I'm not much of a theory chatter ;).

Get yourself a used Signal Generator on eBay for like $30. and start testing.

Hi thaelin,

thanks for your post. I would be interested in reading a report of a power factor correction setup gone bad ;D... if you have a link please post it. I know a little about power factor correction and that some are in the business to offer this kind of service mostly to large commercial electrical consumers but never though it could start resonating ;D... man! that could be scary :o

I really like your idea to purposely create Resonance and tap only on certain harmonics... a great idea I must say ;D

I was also thinking of creating a rotating resonating toroid and your idea should apply as well ;)

Thanks for sharing

Luc

   When you stop to think of it, SM did say there was 3 coils all the way around.
That sounds like 3 phase to me. 3 phase 35k and working the harmonics in
on each one. One for self power, the other two for output. Hey, who knows what
would come of it.

Hey gotoluc. Check this interesting LC (I would think it might work as LC not sure about those diodes) pickup coil setup. Do you know the frequency of your secondary pickup coil standing waves the one that you aim for? You could tune your secondary as LC with those (I would use tunable) 2 caps. If it is LC..

Here it is: http://hibp.ecse.rpi.edu/~john/hi_power_xtal_set.gif

   Hi Luc:
    Hey , have been really busy with the rally up comming here. Just realized I hadn't posted
the power factor file. See below.  Its a blast.!
