Interesting that you mentioned that L1 carries a sine wave. In my setup, L1 presents a square wave and I can only see a sine wave on L2 and L4, but L1 definetely has a square wave. Maybe I have a smaller coupling coefficient because L1 is movable.

Probably, as my (resonating) L2 coil is wound directly (only seperated by 1 layer of isolation tape for smoothing the surface) over L1.

You can see the L1 and L2 sine wave signals in my video in post #925.

@Itsunadze What going on ?? Have you some interesting and great news ??

Удачи Сергей В.

Nope,  tuning this thingy with all different parameters takes time.
Other then lighting a 12V/21W bulb at half brightness with a spikey sine wave like signal
at 80W input, no interesting and great news to report.

All,

After spending last week(end) many hours in tuning my Dally replication circuit, i have come to the conclusion that with the knowledge we have now on used frequencies and voltage levels, its almost impossible to find the correct combination (if it even exists) where the magic happens.

My L4 coil at best shows 100V sine wave with some nano-pulses riding on top which are not doing any good and causes a 230V/60W bulb only to light dimly (with or without the nano-pulse active).

Increasing the nano-pulse repetition frequency above 20Khz or so, causes the little toroid and the DSRD and even the series capacitor (9nF/3Kv) to heat up significantly.
As there was mentioned to install the toroid on a heatsink, this points to the fact that this repetition frequency was high, however, the pictures and video from Dally did not show this heatsink.
Anyway, even with this increased frequency, no extra gain was ever seen.

So untill i got some more/better info from Dally (as promised) on used frequencies and voltages, i will put this project on the back burner.

I could try to fill the coil with ferrite bars and/or rings to see if that gives anything extra but as Dally never mentioned he used any, this is just a shot in the dark.

Thanks to everybody for giving directions and help especially "verpies".

Itsu,

Before you put your tuning on a back-burner, try running your inverter at a much lower frequency down to as low as 50Hz, with the nano-pulser at around 2.4KHz.

Hoppy,

i went as low as my inverter allowed me to go which is 1.7Khz and putting the nano-pulser at 8Khz, see post #925, but other then a nice spikey signal, nothing special.

Getting my L2 coil (1.5mH) resonating at 50Hz means a capacitor of about 7000uF, not to mention the build/modification of a new inverter.

I could see what happens when driving the L1 coil with my FG (puts out 30V pp).

Regards Itsu

I see the difficulty. I suggested this because as you know, I queried the core material in Dally's transformer and I still think its most likely a steel tape toroid. Also the caps on his inverter board look bigger than the circuit schematic shows.

Guys, while this seems to straddle several devices and my comment maybe off base to the dally experiement, Isn't that what the COAX could be? a capacitor with a coil? It all depends on how you connect it right? open ended COAX with the braid stripped back far enough to avoid arc over. What is the capacitance per foot, size it against the inductance of the coax coil, provide self resonance (or damn close). Use another coil as the resonator and perhaps another as a bias coil, just some ideas.

I potentially see COAX being used to take the place of a high voltage CAP and coil, the simple design would be a diode, a additional CAP to tune, a sparkgap and a pulse circuit to generate a couple of KV in the cap coil

Nonetheless, you have learned a lot during this project and your TDR experiments, and I think your wires will always be shorter from now on

The worst thing about this Dally system is the unknown operating principle - if it has any.
Note, that we managed to get the exotic DSRD effect to work at 20kW peak power, because we knew the operating principle and what to strive for, what to verify and watch out for.  The same goes for the lossless clamps in the T2 circuit.
I am not sure that magic can happen with Dally's setup, although Tiger's video showed an inspiring behavior of a similar circuit.

There was one anomaly, though.  Namely nanopulses exerted influence outside of the coax, and they should not have had.
There was no standing wave formed inside the coax because it was too short to allow the incoming pulses to meet the reflected pulses, at such short pulsewidths and PRF. 
Maybe the coax was leaky, or it was EMI emanating before the coax entry point, or maybe it was the AB Effect.  It's worth investigating further.

The heating and damage to the little toroid is fishy, too.

If Dally will not be forthcoming, I think it is worth a try to reuse these electronic circuits to experiment on related devices operating on the known  but underappreciated principles of:
1) Stimulated beta particle emission and confinement, as described by McFreey in his spool devices.
2) Magnetoacoustics, as described by Gunderson.

If you think that the ideas of other users have merit  (e.g.: sychronizing or nanopulsing only in the 1st and 3rd quadrant of the sinewave) then I will gladly help you out to achieve these operating modes.

They are not operating principles, though...

I don't think this will bring any advantages but have no idea if this is simply done or takes elaborate electronics to accomplish

Irrespective of whether Dally did or did not achieve self-running, he has at least motivated a few of us to attempt a replication to chase that elusive OU. Also, credit to him, as at least he did publish enough information to make a replication a practical proposition, something that very few other OU claimants have been prepared to do.

Its been a pleasure to watch your excellent videos and marvel at your patient and methodical approach to your testing.

Hoppy
