I have spent some considerable time with this and I must conclude at this point  that my ferrite does not do the job despite having the initial peaks in the right places .

For now I am blamimg the core

I would like the Team or energia09 to measure the resistance of their  special  russian yoke or confirm that non conductive ferrite works.

This is the third time i have  asked this simple question

Most all of the later ferrites are NON conductive types.
Most people here will be using non conductive ferrite.
Any body got light with non conductive ferrite
Or does it need to be barium ferrite for this reaction to amplify?

ATTENTION ALL:  There are new HV transformers  available (without any diodes) at Goldmine Electronics for $4.95

Look under the Transformers heading, I can't post the link for some strange reason???

Of course one can do many things to protect a circuitry by HV at low frequency as correctly you said (zeners, varistors or even blocking capacitors of very small capacitance -high pass-)
Why no mention it so far?

Yes i am sure.  In the second "part" of the english translated video, at 42:00 - 44:00 when getting nice sine resonance at biffilar it goes (as Wesley descibes about the usage of attenuation probe 1:1000) above 6 Kv (biffilar) at 1.1 MHz. I can accept that.
 
At the end of video with the use of mains transformer for getting thse 50 Hz at 15 turns primary, @ 1:31:00 the biffilar forms some 10 Kv if i get it right.
Since all have been wound on same core, the 50 turns and the 15 turns should share more or less a 50/150 and 15/150 voltage ratio of those huge Kvs. Not to mention the examined biffilar coil set is nowhere near 150 turns.
No?

DIY High Voltage Probe for digital multimeters

AND you can get one of these resistors in the meg ohm range out of an old CRT, they are used to bleed off the HV from the CRT when the unit is switched off.

Here is a link to a book that tells you all about TV yokes and ferroresonace.

Hello all,
Who said we are all theories in here? 

I lack a decent signal generator, therefore i tried to assemble one, actually an high frequency inverter run in a forced mode, taking the pace by a Variable control oscillator.
Ok, not the best thing to have around in investigating ferrite's singing frequency, but it gives an idea what the STAAR team should do in order to dispence with the FG ect and make a stand alone unit.

...
For those interested, the below inverter have the major flow that for a given C capacitance it operates in relative norrow frequency and load window without any serious wave distortion.
On the other hand, it outputs like a FG (specific frequency), its voltage amplitude can go as much as anyone likes to go.

In that setup i have (x10 probe) some 75 p-p open circuit up to 2+ Mhz. By applying a minor load, as 3w, 12vbulb, the amplitude drops dramatically, that with extra C tunning can be as much as 20-25volts p-p. I estimate some 0.2 amps (in dc terms circulating by seeing bulbs brightness)

Anyway, i plan at perfecting it. This way, if my cores have a 0- 2,5 Mhz singing frequency, i will find out by large amplitude voltage application of that shield.

@wattsup
The scopeshots are what I asked for, and they give me info about the output stage capabilities of your signal generator.
Please answer three more questions:
1) Do you want the VCVS buffer/amplifier to handle rectangular waveforms only, or sine waves as well ?
2) Do you want the VCVS buffer/amplifier to output only pulsating DC or full AC signals ?
3) Does your signal generator have separate outputs for the sinewave and rectangular waveforms, or only one output changed by some mode switch?

@verpies

Sorry for the delay in responding to your above post. OK, I want to answer your three questions but first I need to explain something that is rather important to take into consideration.

When I had my previous flyback transformer (FB) the circuit (shown below flyback-howto1b.jpg) I used was fixed and ran well using my power supply with some good output, but the flyback, the real flyback that returns from the primary was hitting my power supply with some high voltages and even high enough amp spikes that made the meters in the power supply go haywire. I am not talking about the BEMF (primary coil resistance to initial pulse change) but the flyback that the primary produces at pulse off was in my opinion rather extreme.

My pulse generators (two HP 8116A and one HP 8111A) alone could not handle that kind of flyback. Actually that flyback could not even be produced by my FGs because I do not have high enough voltage/amperage from the FG pulses only. 

So the idea is that yes I need a circuit that can be between the FG or FGs and the FB primary, but if the circuit uses a mosfet that has an internal diode, that diode will be hit with flyback after every pulse.

So what I am thinking is first to use either one or two batteries instead of my power supply.

Then, in my research of the Tesla Ozone Patent, in searching for a good transparent mosfet for the make/break switching, I purchased two Semi-South SJEP120R063 (T1009) and two Semi-South SJDP120R085 (T1009) JFETs as shown below (rather expensive). These are used in high end systems and do not have internal diodes. I think these JFETs would do a good job. One JFET to pulse the FB primary and when the first is off, the second connects to send flyback to the battery. This is one alternative.

But I think there may be another alternative and for this, one has to consider why the primary is producing flyback in the first place. I think the flyback is due to the simple fact that the primary is being pulsed only from one side of the primary coil. I tried explaining some of this some time ago here.

I know this may be controversial and I do not have a better way of explaining it. I'll try it again with this analogy. When a coil is pulsed from only one side (PS), the pre-connected (PC) side acts like a spring. When the PS is not connected, the PC spring is relaxed. When the PS is connected, the PC is now pushed inwards and under stress from the PS influx. When the PS opens again the PC spring just shoots back outwards and in doing so expels energy and this is how your flyback is created. So the idea is to eliminate the spring action by using two contacts, one on each side of the coil. This way there is no relaxed spring, hence there cannot be any stressed spring at pulse on or spring re-coil at pulse off. Both sides get pulsed at the same time and get disconnected at the same time, so the energy will only have one way to go and that is out the secondary at higher force.

Anyways, sorry for rambling on but I think at this juncture it is important to consider such things if trying to build the next step for experimenting. With a circuit diagram, I can go to my local EE guy and have him build me the circuit. If you think of other checkmate conditions that we can avoid at this stage, please let us know.

As for your questions;

1) I would like to use the full flexibility of the 50MHz FGs which have sine, triangle and square, up to 16vdc and variable duty.
2) Hmmmmm. That is  good question. Seems that the complications would double with AC. I think that if I wanted just AC I could use an H-Bridge type circuit. I don't know about that one, saying yes could add to the circuit complexity, saying no would eliminate a whole realm of experimenting. I guess it would depend o the actual complexity.
3) My FGs have one output via a mode switch  but I have three FGs so I guess the answer is yes and no.

Anyways, I just wanted to give you some impressions of how the primary could be driven but I do not want to create any overly complicated circuit. Maybe two simple circuits, one on the positive side and one on the negative side of the FB primary, driven by two of my FGs would be the best and most flexible solution.

@itsu

It would be good to know what are the output capabilities of your signal generators for sine and square waveforms.
If you you could do the same tests as wattsup below, we would now what kind of output distortions happen with your rigs.

Below are images of scope with 10 ohms and 100ohms resistor load (non-inductive) with frequency generator set at 16vpp, 50% duty and 100kHz.

My comments on your last video would be much more informed if I had this output capability info.

 I too believe something is changing in the Ferrite core. Maybe these are the same waves just out of phase. The ferrite acts like a lense to both waves, redirecting the pathways and combining them in one output. When in normal alignment they convert one type of wave. But maybe they are converting two waves(electric and magnetic) at the same time when flowing through this dual polarized core? Piggy backing the two together making it really strong??
