1. Sinus wave.
2. http://freeenergylt.narod2.ru/aidas/3_pirmine_iskociojimas_pjuklas.jpg - input is square, output is sinus in resonance.
3. http://freeenergylt.narod2.ru/aidas/4_spagep_kontur.jpg - you can emulate HV discharge with wave like this. We skipped that in experiment, 1.+2. (2.5W+2.5W) was enough to light up 150W halogen.

Don't you use for 3. capacitor in paralel so that 90 degree coil self oscillate at its own natural LC frequency which is given by spectral analysis

1. 2.5W for 50 hz sine (the same for 380 khz), HOW is that possible, if sine has higher amplitude than 380 khz signal ? Also ferrite coil impedance is MUCH MUCH lower for such low frequency ?

I don't think the inventors have measured the power fed to the LF and HF primary windings.

Also @ Grizly,
From scope shots in both cases, since the channel 1 of the digital PC based o-scope is used the volt/div is 20V.

...
I have already asked this question. IMO its best to clarify power measurements to have a reference ground. Its good for all

I explain. Maybe the Signal Generators are destined for 10v p-p at fraction of amp, but during the resonant rise of the windings (that effectively can be depicted as parallel LC tanks circuits in impedance terms) the voltage at:
 
-Primary A 50 Hz 15 turn is 120 Volts p-p or some 40-45 Volts AC (rough estimate)

-Primary B 380Khz 50 turns is 75p-p or some 28 Volts AC

So, in my view, if the SG manages somehow (without burned obviously) to feed Primary A @ (say) some 0.25 Amps (while in resonant rise) at those 120v p-p (as oscillograms suggest) or 45 AC then the power in would be some 11w and not 2.5watt

Respectively the Primary B would input some 6.5watts if fed with 0.25A at those 28V AC (35v+ p-p)
ANyway those figures if true, clearly they suggest OU.
....

Anyway, we expect fully exploration and documentation of the effect by the TK replication team and potential other replicators.
Tinkering at its full glory

Regarding the FG outputs, my FGs gives me 16v or 8v p-p. The way I use my FG is simple for me to see if there is any OU before I need to do more exhaustive input and output measurements. For me it is simple because I always use the same output strategy which is my diode to capacitor with a LED bank as load. I already know that when I connect my FG directly to the load, the maximum I can get as steady voltage on the capacitor with load is around 9.34 volts with the load on. So during my testing, if I see the voltage rise to that level or more, then I know I have something special since I use a small 10uF 370v capacitor that acts as the RMS agent. This way I can do low level testing, find resonance frequencies, measure output and see where the best settings are, then it is to re-do the same with a solo setup if the preliminary results warrant it. In my last video with the standard yoke coils, I managed to get it up around 8.65v by shorting the analog coil of 50 turns. I will know soon enough once I have a yoke wired up like @T-1000.

@all

Well I have my other Yoke.

OK, I know guys want to theorize in the last few pages but there is no point to that. The doing will tell it all and right now, for us,  @T-1000 has the highest insight. Once I make my coil, I will do some hunting.

Just to have an idea, can anyone with a built yoke of 18 awg wire, please check your coils for ohmage and if possible inductance. I have not wound mine yet cause I have to get the wire but the type of wire is my present questioning. To know the type of wire, I need to know why or how this fits into a circuit in an effort to build the Yoke Coil with the lest checkmates possible. That I don't have. So what do we do?

I see that @T-1000 wound his yoke using the same 18 awg stranded wire for all three coils and he is using a copper strip, while I see @stivep using single strand wire and his strip is a thick braided grounded lead. So which way to go. What I am really worried about is the copper or braided strip that is going to receive the high voltage. Well the copper strip is not insulated and what will happen when the HV hits it. It may be causing internal arcing. The same goes for the braided strip which would be even worst. So I am thinking that the copper strip should have some coating to isolate it from the two primary winds. @T-1000 fixed that problem with his wire be plastic coated but the wire is stranded and not single strand. So I guess all this will be part of the R&D aspect.

So for me the most logical is as follows;

1) Copper strip must be insulated with not more then one layer of electrical tape and the strip should be long enough so the actual HV connections can be made as far away from the Yoke as possible.

2) 15 turns - Well the build says to put the 50Hz there but my preliminary FG tests show that the 15 should receive the highest frequency. I tried it the other way and the results where not good. High frequency does not require many winds to impart the effect. Even a few turns would do the same job. So I think I will put single strand but since it is only 15 turns that will be on the top, this can be changed quickly to other wire types if required.

3) 50 turns - The build says put the HF here but as discussed above, I am not sure about that. Since this 50 turns wind goes on first, I will use magnet wire to get the greatest punch effect against the copper strip and yoke.

4) 150 turns - This coil will be on the other yoke half so it will be best to just put magnet wire on that one. The only thing is how to make the bifilar wind. When you wind the first layer from left to right, do you continue to wind the second layer from right to left or do you go back to left and wind to the right again. That is my main question for the 150 turns. Also when we say 150 turns bifilar, does this mean the output coil will have a total of 300 turns?

My main worry is when the HV is connected and how the copper strip will act against the other winds. Anyways I have three FGs so I can do the low level tests pulsing the copper strip and the two primaries.

Thanks for the warm welcome Wattsup, Sad to hear you burnt out your Flyback, this raises a couple of questions for me to ask you though, hopefully we can save your next one...

did you have the flyback immersed in oil ?

if not, the pin outs at the bottom,  were they arcing out? (most comon cause of death with a Fb is pinouts arcing from the HV ground and sending low KVs though the primary wind they really don't like that)

lastly what diode were you using in my circuit ?

I will take a good look at T1000's circuit tomorrow after a good read of the forum and good dose of sleep. Maybe if he reads this post over night or if anyone can tell me can throw me a line as to what is going on with the Sec winding, HV winding and the circuit half to the lower left of his schematic, I cannot see how the FB's HV and sec winding are even interacting with the rest of the circuit, it seems to be of 2 complete halfs with no connection.

anyhow off to bed. I will check back in the morning.

@KultusNagrand

No oil. At OU.com we are trying to get rid of oil. lol

Yes there was some arching and some funny noise from inside the flyback coil. I think it was when I tried the center circuit I had passed the pin 10 through pin 4 and 5 and put a capacitor across pins 7 and 8 to replicate the center circuit. This may have weakened the coil and when I did some other tests mainly on my TPU mock-up, it blew the flyback. Does not take much for them arcs to destroy any of the internal coil strands.

I forgot to mention that when I tried your circuit the 0.01uf capacitor did not work for me. But after trying to many caps with no success, I tried a small inductor and it worked perfectly.

When I found a capacitor replacement.

Hey guys do not hammer all together

@ itsu, wattup

of course the 50Hz winidng cannot form alone any resonant effect without any cap added, but as i see it, the overal voltage rise effect that the TK replication team reports simulates an LC resonance mode. Its my view..

@ Verpies
Of course we are not dealing with DC in such systems but the AC seems to me more or less sine wave. So according my poor knowledge, AC voltage of sine wave   = p-pV /(2*1.41). Of course those are rough considerations.

Of course i can be wrong here. The overal idea anyway is to have firm power measurments of those SG and eventually make custom inverters and dispense those SG altogether. That way input will be monitored best.

Unfortunately it is not so simple.

1) First of all, the HF is a rectangular waveform
2) Even if the LF is a perfect sinewave and its RMS Voltage is 7V (Vrms = Vpp / 2^0.5) and its RMS current (Irms) is 178mA then the real power in such circuit can be anywhere from 0 Watts to +/- 1.246 Watts, because the phase shift between the current and voltage is wrongly being ignored in the power calculation.
