A video showing some strange behaviour on my rig, any theories to explain this?

Hmm, i also have no standard explanation for that, but maybe there is one.
You are probably spot-on right with the aetheric inertia,
also the jet turbine start up of frequency just like in the TPU for example.
That is actually a remarkable find !

What colour does the output spark have to your eyes (camera shows it blue) ?

@Peter:

Nice video, cool lab set-up ;)
What do you mean with Blockingmono ?

the output spark appears very similar to the eye, blue.

It might be eroneous, but maybe the ions (ozone ?) in the air surrounding the gap make the ionisation easier if you start it up again shortly after.
Maybe you could try opening the windows and whirling air around with a towel heavily and make the experiment again and see if that changes anything.
Well, really not sure about that though, you said it can take hours.
In that time the air would have well circulated anyway by itself.
Sorry, just an attempt to find an "ordinary" explanation hehe.

I´m pleased to hear all ideas, I had thought exactly the same as you. The room has a ceiling fan in it and it shows the same behaviour when that is running.

I had also thought that maybe the diodes and/or cap were heating up as it ran, but they stay cool to the touch at all times. It´s still a mystery, maybe it´s a glimpse into the magical realm of this device?

peter, your HV supply and multiplier in the video looks like it could be useful for these types of circuits, nice work, modular units are very handy for trying different things with.

Your LOPTX based device will probably come in handy too, must have a reasonable power if you got a lifter up with it. I´m pleased with the performance of my LOPTX HV module running in self resonance with one transistor, it´s opened up the world of HV to me. (maybe youve seen this vid already):

edit: I missed this earlier:

Now i know i am not strong on theory but when i think about the way the secondary is wired in parallel and then think about a conventional transformers secondary then i would imagine that they are subtractive and the net result would be very little output.
If he used 2 20 turn secondaries and wired as per a conventional transformer secondary we would get double the current, so i wonder if he has made a mistake in the drawing after all he does show 2 separate secondaries not 1.
My guess is that he is trying to receive 2 units of energy for every 1 unit he puts in less losses.

Smiths diagrams do have contradictions in them, purposeful obfuscation maybe? Smiths HV power module (laser PSU) is probably a few watts but he claims kW figure on the output. But your 1:2 theory sounds more believable lol.

Yucca,
Perhaps the surrounding air moisture is responsible. Try heating the area surrounding the spark gap with a hair dryer/air gun. This should give you a clue.

Thanks for giving it thought, but I think I may have worked it out... The cap on the HV module DOES get quite warm when running, this maybe causing it.

I was only thinking about the aircoil board parts, sorry guys!

If you have a 2nd equal cap, you could make a switch and switch between them and see if that changes when using a cold unused cap after operation. But that might not be of priority for you hehe

good idea, I´ll try that tomorrow.

Yes the secondary seems like copper litz. I have bought something in a store that looks exactly like it. (It is more suited for RF signals)

The questionmark device might contain inductors (probably two of them) but since this seems to be NOT the output transformer (because too small for 30 kW) i can not
identify its function and what might be inside.
Don Smith refers to it as the feedback system on his website, however it seems not to be wired to the primary-side inverter. So maybe he talks about another feedback than to the primary ?! Something that might contribute to the secondary functionality maybe even ???

Hmm, so you also think that the two little components could be resistors, that was my first thought, but i could not explain their presence at that place in the circuit would it be resistors. Or maybe also diodes? From just the appearance they look like smaller HV caps, something like in the 3-6 kV region and few pF capacity.
The fact that Smith paralleled two diodes in the bottom part indicates that he
has already quite some amperage flowing to the caps.

Nice that you nearly have all components together. Do you also already have comparable HV caps with enough power rating?
Looking forward to seeing your set-up soon ;)

The slidable primary can be seen in the 3rd pic.

Hi xeno.

it is very much like the MIT Physics Demo -- Resonant RLC Circuit

Pretty interesting stuff.

Yucca

Here's some info on the blocking mono 5th paragraph is the circuit i used, but tailored the ferrite core windings.

http://mysite.du.edu/~etuttle/electron/elect37.htm

I have used a line transistor to handle high voltage, i have found it to be ideal for producing HV pulses and because it can be triggered using a sig gen can be driven at different freqs.
It consumes very little current and runs cool.

It can be very hard and unforgiving driving LOPTX's, your driver circuit works great, i built mine 5 years ago now, i used a 555 with a pot to set the freq and used a novel fet push pull stage, it has served me well during lifter tests but the fets do run hot after a while so it's only good for 5-10 minuet runs.

Regarding you gap fire speeding up, Nice setup ;) i would be surprised if it is the cap getting hot but don't know the answer, maybe you are building up electrostatic charges in the room.

xeno

It's hard to swallow the KW's of energy that are being quoted for Don's device, i think the best course of action for me is to do a rough build using lower grade components as these are readily available but keep looking out for bigger and better components because this could take some time and money.

Looks like you are way ahead you've done a fantastic job with collecting information for which we are really grateful -- Thanks.

Is anyone familiar with the make of spark coil he is using looks like Bertonee?? but not found anything on google but not sure of the first letter

Cheers,
Peter

@Jerry,

thanks for the link. I had watched all the lectures, but did not stumble about that experiment. It beautifully shows the tuning like in Smith`s device.


Bertonee are now called Ventex
http://www.ventextech.com/#neon!Energy%20Efficient%20Neon%20Power%20Supplies

Peter, thanks.
I usually try to gather as much info as possible before buidling something and since Smith is so cryptic about the functionality of his devices, i think it is most valuable to understand the principle before building something. Otherwise one doesn´t know how to seek errors and optimizations.

You are right, we all have a tight budget.
Kapanadze`s early devices would be cheaper to build compared to Smith devices (no expensive caps),
but unfortunately no-one has figured out yet how he manages to keep the resonance
when hooking a load to the output.
Smith solves that by storing the energy in caps and then converting to the desired AC output frequency/voltage with the output transformer which galvanically separates the load from the secondary oscillator, so it could not kill the resonance whatever resistance (inductance) the load has.

Good job on finding out that Bertonee is now ventex.
I guess you meant Neon power supply when you said Bertonee spark coil ?
The particluar model on the table device is described by Smith to be
a 9 kV 30mA model (very likely solid state) with a neon dimmer attached to the side.
I browsed ventextech`s website and your new info narrowed the possible output voltage range for the constant burn 12V NST in the small suitcase model (1500-4000V, but more likely 1500 V)

http://www.ventextech.com/#gen4!12%20VDC


I am looking forward to replicating that one too, however i still don´t entirely understand the schematic since Smith indicates a DC out coming from the NST (?!)
and it is a riddle to me how the big cap bank is supposed to magically convert a high frequency to a low frequency without commutation of some sort.
Also the cap bank is stated to be made for DC  in this schematic too, which
contradicts the necessity of AC caps in resonant RLC circuits for the oscillation, so that the caps won´t get destroyed by the wrong polarisation.

Thanks again,
Xenomorph

Hi all,

the change in output gap freq was definitely due to my input cap heating up, I tried swapping out for a cool cap and it started slow again.
