Resonance Effects For Everyone To Share

[Armagdn03]

Yes that is similar to how I found the resonant frequency. However its not quite so cut and dry. Once all of the pieces are put into place, they have relative capacitance and inductance to everything around them, the higher frequency you go, the more these things affect the resonance of the coil as a whole. Due to this, resonance is found more easily when the whole devices is assembled, hence the use for the taps.

As for the primary, there is no cap attached, rather it uses the self capacitance of the coil itself. Also, (and this is getting a bit ahead) the secondary will push back on the primary in an interesting way causing a feedback. The idea is to have amperage manifest at the two ends with an amperage node in the center of the secondary. This equates to half wave resonance, with voltage nodes on the ends, and voltage max in the center, electrically. Maximization of the voltage and amperage maximums yield higher output, this can be accomplished through increasing the relative permeability and permittivity of the various stages of the device within reason (don't throw things out of resonance)

This device will have a lot of people up in arms about which models to use to characterize its operation, and black and white instructions on building similar things are not easy, bench time, and practice help a lot in tuning.

This setup is very similar to one suggested by Avramenko, Tesla, Kron, and others.

Also notice that the output is only half wave rectified in this demo, full wave is obviously possible.

Keep up the good work guys.

Hi Armagdn03!


How did you find the resonant frequency? I would just connect the signal generator to the primary, attach a bridge rectifier and a cap to the secondary and then just sweep through the frequencies, watching the voltage on the cap in the same time. As soon as the voltage reaches the highest level, that should be the resonant frequency, right? Or did you do that in
some other way?
Also, did you use just the signal generator as the input, or was there also a cap? If a cap was used, was it in series or parallel?

Thanks!

Armagdn03,
Great work!!!!! I was particularly interested in the comment you made "before the use of the signal generator was deemed not necessary". Have you tuned into cosmic/terrestrial frequencys, or using a spark gap or something now?

They've been talking about winding coils on page 8 of the grey tube thread. Interesting way of winding tesla used, and your wire is already Bifiliar :-)

I've been thinking about ways of duplicating your work without a signal generator or complex circuits to handle the high voltage, and I've come up with some ideas..

The imhotep radiant oscillator generates high voltage ac. I've been teaching myself about spark gaps and electromagnets, thru trial and error and much deliberation..

It finally occurred to me that the capacitor to strengthen spark voltage climb should be in parallel with the spark gap, and a home made variable cap is quite easy... Found a link here;

Spark, Bang, Buzz and Other Good Stuff.

(there is also a home made borax or baking soda and aluminium diode / rectifier link)

Also, an electromagnet with potentiometer to limit current will control the extinguishing of the spark.

The current to the imhotep oscillator can be limited in the same fashion, and will also help adjust the frequency of spark discharges..

Voltage divider circuits : DIVIDER CIRCUITS AND KIRCHHOFF'S LAWS

I'll let you know how it goes.. Might not be able to have it running on almost no amp draw like you, but maybe at high voltage the returns will outweigh the extra cost of breaking the dipole...

Ps here's my imhotep circuit in case you wish to share this post with overunity.com thread.

Here's me picking up radiant energy from capacitance, and lighting a neon with an open circuit; once I disconnect the two green alligator clip wires, I'm collecting it from two places with two open circuits..

And here's a radiant energy detector I made based on that observation and a little prompting from Vortex

YouTube - Inquorate 22

- I'd be interested to see what it picks up from your circuit when in resonance and when not, and also when you're collecting the energy off the coil, if it comes out of your caps, and if they can be shielded, etc etc......

Love your work and following it closely :-)

Hi Inquorate,

very interesting ideas and great information you have shared there

I am also quite sure we will be able to find ways to eliminate the Signal Generator as Armagdn03 says he no longer has need for it.

Armagdn03 is way ahead of me so we need to pay close attention to what he shares. We also need to keep in mind that his time maybe limited compared to ours.

Keep us updated of your findings usable or not since it could help others from duplicating what is not needed.

Thanks for sharing.

There are many interesting configurations which can be tried. The secondary can be wound in several ways, as shown it is being used as a 1/2 wave helical resonator, with ends open. With respect to the inductive transfer, don't automatically assume that the magnetic component is the only one involved with the inducing, capacitive is often ignored.

The primary has the taps for ease of experimentation. Its a good idea to make the various variables tunable to begin with saving time down the road. The next version of this coil had taps on the pickup coil as well.

The fine wire coil (secondary) was not tuned, it was wound, and the rest of the coils were tuned to the secondary.

Hi Armagdn03,

thank you for taking the time to post this information. I know your time is limited, so I really appreciate your help.

@everyone, with this said!.. I ask that you take this into consideration before asking Armagdn03 more questions. Jetijs just saw Armagdn03's video and that was enough for him to build it I think this is a great approach since building is the best way to learn. I also think we have enough information to do so. Maybe after we have built and posted pictures or a video of our device and we need help on things that have not been explained or shared, then we should post our questions.

Let us use time and resources wisely

Thank you all for your interest and for understanding.

Here is a OU post from Armagdn03

Here is a great article which shows a good model on which to base helical resonators. This is important in understanding 1/4 1/2 full wave, etc resonators.

Class Notes: Tesla Coils and the Failure of Lumped-Element Circuit Theory

Here is a video I uploaded yesterday on my testing of different coil winding method, wire and or geometry to see if I can find any benefits compared to a standard winded coil using enamel magnet wire. I found nothing of benefit and I most likely don't understand what Tesla was using his pancake coils for

This is a reply from OU user: sparks

@gotuluc

I believe it is user Tinselkola that uses a bifilar wound primary and top wound bifilar coil. Tesla did not pulse these coils directly from the oscillator. He pulsed his primary winding of two turns with the bifilar coil INSIDE the primary. He then extended one end of the bifilar to an elevated top load and the other end to ground. This was the configuration for the transmission of power. The impedance match is built into the bifilar coil with strict adherence to the voltage developed between turns of the spiral (capacitance developed within the coil) and inductance of the mass of the copper.

[cody]

Luc,
You may already know this but, with tesla coils the pancake coil configuration is used in the primary because its the easiest way to get a tight coupling(good energy transfer) between the primary and secondary, without getting whats called "flashover" between the primary and secondary. Flashover is an arcing between the primary and secondary that will destroy your coils and is due to the extreme voltages tesla coils generate. I have no idea if that is all it could be used for, but that is one use that i am aware of.

[Jetijs]

Pancake coils are interesting. You can easily imagine what a magnetic field looks like in a typical coil. But it is harder to imagine it on a pancake coil. To me it seems that in pancake coils the magnetic poles would be in the center of the coil and on the outer perimeter of the coil.

[cody]

Jetijs,
I believe you are correct. The magnetic field in the center would explain why you can still have a tight coupling with only that center part in close proximity with a secondary coil. Furthermore, on the outside part of the coil there appears to be something different than the magnetic field which is why if you get the outside part close to the secondary in a tesla coil you get that flashover i was talking about. Perhaps this is the separation of inductance and capacitance within a coil that armagdn03 was talking about. So maybe the center part has high inductance/low capacitance,and the outside has high capacitance/low inductance.

Again my 2 Cent.

I think, both Coils are fine, either Aircole, or Teslacoil so far they attached together.

I found a small Dynamo from a Lamp where the Generator is made from more a Pancake style Coil.
At this Coil is at one Side a round Magnet attached, what have pretty the same size as the Coil.
There are further 2 Sheets, what build a cross, typical for Dynamos, but thats not really importend.
At all, it generates nice Power for the Batts.
When you attach 2 Coils together, they come into Resonance. Or sometimes not. lol.

I build another Coilset for my Bedini, now with 3 Coils behind.
Left Trigger-, Middel Power-, right Side Semi-generatorcoil.
They are all attached behind too, so that one Coils is behind the other and only parted with a Cd.
Now i got a strange Effect at the Oscilloscop for the BEMF at E and C.
The Spikes look like a Rollercoaster.

That Picture above from the Colermachine is maybe not complete.
Someone mentioned, that he did put the Aircoils stick into eachother.
So, the machine maybe only first did run, as he did stuck them together.

Attached another Picture from the Circuit from the Colermachine.
Its a resonance Circuit, the switch at the middle will be closed for adjusting it.
After it was done, the switch was opened again.

Now you can count 1+2 together.
Rollercoaster BEMF, a resonant Circuit with this 2 small Caps at top,
a thick and thinner Coil attached together, an adjusting of the Circuit, and then, open the Doors.

[Joit]

And to confuse a bit more, another Picture.
He did wound the Coils sometimes counterclockwise, sometime Cw.
Another Picture of the Coils.
rechts = right, links = left.

[cody]

I thought i would provide a picture of the physical placement tesla was using between his primary pancake coil and his secondary coil, at least the only configuration im aware of, im providing this picture. http://www.easternvoltageresearch.co...tc2_coil01.jpg You can see the regular coil is placed inside the hole of the pancake. Just to show how close the inside part of the pancake can be to the secondary, while the outside of the pancake must stay far away from the secondary or you get problems(arcing), suggesting that there are two different things happening at either end of the coil. Luc has already provided great information on the high voltage present on only one side of his coils. So what is happening on the other end.... The magnetic component? Am i going nowhere with this or what?

[Armagdn03]

Luc has already provided great information on the high voltage present on only one side of his coils. So what is happening on the other end.... The magnetic component?

Bingo! (if you are dealing with quarter wave resonance in a distributed slow wave helical resonator (fancy for Tesla secondary))

[Joit]

The Northpol is allways, where the current goes too.
And the magnetic Field is allways around or close to the Wire or lead

So, its more like, that the Pancake makes a stronger Field at the Secondary.
A Pancakecoil center the Field at the middle, a Aircoil makes a larger Field.
I think, that at bottom, where both Coils are together is a stronger Field as at Top.
I think, the large Nordfield at top plus the switchback to the Southpole to the Bottom causes high Bemf or Hv like the Distance at an interruptor.
Would be interesting, if he use AC or Dc or pulsed DC for the Coils.
I saw lately some original Resonancercircuits from Tesla, and he used at most a Relay in it.

[cody]

Jolt,
Interesting thoughts. But im not sure if we are even dealing with a north on one side of the coil and a south on the other like we typicaly think of a coil having. But instead the focus is on the fact that under the correct resonant conditions, the current is not the same at all points on the coil. So the end with the most current should have all the magnetic/inductive effects i would think. And the other end with the high voltage has a capacitive effect i think, but im not sure if it contains the other polarity . Either way, i think the point is to understand that these remain separate because they are standing waves, and that further harmonics of the fundamental will allow you to create points of high voltage, or current, not just at either end of the coil, but also at points in the middle of the coil. Knowing what pole is where is a good thing to know for sure, but since we are dealing with an alternating current, im thinking that both poles are present on the side of the coil with the higher current. These things are obviously significant to understand, but im not completely sure why yet.

[Joit]

There are allways 2 Poles at one Pole, only one is stronger.
So Northpole contains a weak S pole and otherwise.
I can link you a Picture, when you want to see this.
But its true, Resonance effeccts its a different thing from most Development.
Most are scared from it and try to avoid it, or its 'dangerous' and they maybe research it, but dont make public or use it.
I got this Effect from a Electrostatic or Elektromagentic Field at one of my Coils, and anyhow, it should work too, to use and control this Field.
Thats may where the Extraeffects show up then.
But only to figure out, which Coils match to best Resonance together is still a lot Work.
