Hi all,

to find spin next time emptying sink or bath observe !

//Geo  Hi

Any chance you can scope the say  the frequency of your katcher if it was free running or it's pulse width ?
Also any chance you can scope the input winding of the grenade input winding and show it's frequency ?

This information would be a real help or message me, any help would be a great help.

Many thanks AG

Geo:
  Good to hear that you're back on the bench.
  Do you have your set up working as it was before?  If so, I think that the next step is to connect it up to the proper feed back path, to see how well that part of it works, also. As it will probably change all the previous tuning efforts. In any case, that is an important step that you didn't get to on your last videos.

AG,
Yes, observe the spin, it's very important,
 that won't be a problem, when I get the chance I will.
Below you will see the attachment of a scope shot using prob when tesla coil was opperating when manifestation was happening. see those peaks and the dead time? That's what we are after.
mines is not perfect yet but now I know what it needs to be and now imagine that with pulse train after.

Nick,
Oh yeah, has been a while. but the setup is the same on bench since last recordings.
 the TL494 push-pull driver board, has a glitch that needs a fix be for continuing.
About feed back, well it's the last thing I worry about, It would be the easiest part.. but
what we need to achieve first is massive output when connecting load which does not affect the input readings.
About Kacher/Tesla
I was feeding primary 24VDC but i'm for sure higher voltage input should do the trick when in tune.
24VDC was giving nice harvest of backround energy as you saw to the 300W bulb.

Originally Akula's diagram shows how he fed about 60VDC+ to his primary.
so what we all saw on my recording was just a bit of the result of what should be manifesting at output.

Itsu  is spot on by telling about the voltage on the primary by using a DC to DC converter which stalker is using.
That makes the difference if it will properly synchronize. Is the element I am currently missing now for
the tuning I have currently.

Remember how Dniester had long arcs at his antenna? now imagine the input voltage
btw, his first attempt and success was not done with simple kacher, it had the interrupter circuit with it onboard.

try this, The antenna as close as the thickness of your index finger on grenade.

 here you  can see what my prob was getting when in operation since that last video.

Cheerz~

Hi Itsu you referred to a collection of videos on testing the capabilities of the grenade coil I had a quick look an hour or so and I cant find it any chance you can send me a pointer please.

Also  i found this the dally device In the video I cant seem to see the tuning capacitor i was wondering what value you used or freqency you tuned it to I did find some data where the device runs at 100khz approx not sure if that's true or BS.


Here is a video on Harmonics that are related to this problem.

AG,
here some video's about me testing a grenade for frequency response etc:

concerning the Dally setup, i do not remember any variable capacitor being in there.
We had a L2 coil which was only a parallel LC consisting of a coil and a fixed cap resonating around 5khz, see those video's:

 https://www.youtube.com/watch?v=MQUciCy9p3A

https://www.youtube.com/watch?v=utkIltw6WrU      L2 = 5khz


i hope his is what you are looking for.

Itsu thanks for the list I will watch them later on.

Re the 5k paralell filter, I have come across that or some thing like it before but to be honest that LC would only let 5khz through every thing else would tail off, and the caps look a bit large for 5khz 

Re variable caps err alas no such thing here unless you have a switch box (expensive) no I just add or subtract caps till I find it 

So was Dally 100khz - down to 5khz ? that would be in blocks of 20 (harmonics) ? did you get anything at that 5 khz frequency ? assuming he had peek energy at 100khz if you see how my mind is working here 

My model grenade is happy at 1140khz , being dead on 100khz for Dally (what a coincidence ?? wouldn't that change, some place else ?

If you have any other ideas feel free.

AG

The nano-pulser i build was barely able to operate at 10Khz, and neither was Dally's nano-pulser, so operating at 100Khz is out of the question.

Dally was not using something what we now call a Grenade, unless you call his coil combo also a grenade.

Itsu

Hi itsu,

In Dallly case the pulser repetetive rate was not high but the pulse width is what you would need to consider. It is very narrow in nanosecond range due avalance effect created in diode there. And this is enough to create same effect we have with Tesla+interrupter+filter choke. Just on much less output power.

Cheers!

Yes, i know, so therefor the frequency of Dally's setup was not in the 100Khz range, it was set at 4.6Khz, and this was matched by the nano-pulser repetition rate to have
each top of the sine wave interrupted.

Itsu

Itsu forget about the Dally device and it's running frequency I needed the information as a referance in my experiments, so thanks


My experiment on the Grenade
I had needed another winding on the grenade to test, I had some 45mm tube wound it with the recommended turns 1/2 length of grenade wire  and put 1uf across ends (as per your Dally test) and find the rather large  peek approx 1.28 mhz it  then drops in amplitude to naff all but picks up again at 700khz down to 93 khz it remains flat and then tails off as useless as it has no second peek.

WE ARE LOOKING FOR A SECOND PEEK! it depends on the capacitor size !!

you need to take this test/experiment on board.
AG

AG,

sorry, but once again i cannot make heads nor tail out of your last 2 posts.

Itsu

Looking at the screenshot from Geo, i see that his kacher runs at about 800Khz (5 periods in about 6us)
Itsu

   Yes, it's running close to what my Kacher is running at, or around, also.
But, his signal looks different than the fish form wave signals produced by the Stalker type interuptor 
Stalker can also move the signal back and forth, and send controllable packets of pulses. And provide an input of up to 200v to the Kacher transistor. So, I think that it's a good circuit to replicate. If I can find the all needed parts.
   I've been looking for a DC to DC converter that will go to 200v, but I have not found any, as yet.
  This one below is the highest voltage converter from ebay, at 12v to 55v, 4A, which I've seen so far.   DC-DC Boost Step up Converter 5-32V to 5V-55V 9V 12V 24V 48V Power Supply Module | eBay
   If someone finds the 12v DC to 200v DC model, please let me know.
