Hoppy: When I disconnected the RC snubber network, I got RM back. Careful tuning is in order to get the big peaks down but not too low, or RM won't be heard. Without RM there is no magic, no matter where I adjust the 494 controllers, place ferite, or use my magnet on the yoke core.

As I pointed out earlier, chaotic mode is needed for RM. If you feel that this is the magic tuning point, then forget about good electronics practice and work outside the box. I gave up at this point as all I saw was a big increase in current draw, with little increase in output. However, unlike you, I did not have the patience to work at it. You may be able to keep the RM and ward off smoke by using a carefully selected TVS diode and big heat sinks and / or fans.

Hi r2fpl. I don't know what is the correct interpretation of Kapanadze's style of 'grenade' coil,
but Kapanadze takes steps to hide what he is really doing, so some things that you see in his
devices are there to try to mislead or confuse people. 

One reason people may be having a lot of difficulty replicating the Akula/Ruslan setup is
the configuration of grenade coil as explained by Ruslan previously, which a number people have
been trying in the last few years, may not be entirely correct or maybe not a complete picture, or possibly
it is just far from an ideal configuration so very tricky to get it to work. Some people seem to be trying
other 'grenade' winding configurations now, so we will see if that yields any better results for anyone.

As I mentioned recently, Daly just used regular wound air coils and was apparently able to make
his setup self running, so the exact winding configuration of the coils does not appear to be critical
to getting OU out of these types of setups, although certain specific coil configurations may be better
than others.  It seems to me however it is likely that there is something else besides the specific
coil configuration which is key to getting the OU effect. I continue to experiment with different approaches
as well.

Hi, Void,
Maybe secret is not in coil ?
Possible uses: radioactive cobalt. Plexiglass stopped this radiation.
TPU Steven Mark probably too uses.

Only speculation.

  There is now a second new video by Geofusion.
  Check it out. Radio Moscow on just the yoke's three turn coil. Interesting.
   He does not seam to have a heating issue. As yet.
  I don't know why he's not letting us know about these videos.

I've watched both of Geo's recent videos. A few observations: -

His very yuk cheapo ammeter is very likely not giving an accurate indication of current draw and its not clear whether the meter is showing both push-pull and Kacher circuit current draw, as the power supplies may be split.

His push-pull mosfets mounted under the PCB are not fitted with substantial heat sinks and presumably not overheating, so it may be that he has optimised mosfet protection and / or, that his toroidal transformer is matching well to the push-pull, both in terms of physical core and winding config (ref comments from Alien).

No mention of bulb wattage.

Not sure if a earth ground wire was connected during demo.

The optimum tuning point for brightest bulb appears to be when tuned just off RM using hand capacitance.

It appears that full control of the Kacher waveform with the Akula control board is essential for fine tuning and stable operation.

Geo is still running around with bare feet and wonders why he is getting badly zapped! 

What !  are you looking at the right video ? should have gone to spec savers 

Some current legal advice.
may i remind you guys you have a legal responsible for giving knowingly bonafied advice and could be leaving your self open to both criminal and private prosecution if knowingly giving deliberate misguided advice. So if your advising of untested wind ups for the un aware watch your step, things are changing !

  It would be interesting to see if Geo can get the RM sound without the Kacher being on at the same time.  His next video should be with the grenade connected up, and with his pc scope connected up, as well. Showing the running frequency and duty cycle of his new Kacher circuit, and the induction circuits.

   Stalker also has a couple of new videos out. Showing NO snubbers installed, and ringing with 240v to 260v peaks.

Yes, AG is not only continuing his rude behavior, but has also been making ongoing
statements that make no sense whatsoever. It seems the powers that be want discussions
disrupted here by this sort of nonsense.  I can't see the point of sharing info here when
this sort of thing is allowed to continue here.  Good luck with your experimenting guys.
All the best...

Sir
Builders that share their work here publicly are as rare as hens teeth ,AG is one such person
and perhaps some tolerance instead of "ban Him" should be the appropriate reaction ?

we have much diversity here [language /countries] and even amongst persons of the same language
there are terms and phrases which can get the "hair up" ..
The term taking a piss [UK slang for Joking around} had me sharpening the knives for a fellow ....

and he meant no harm at all ,I just misunderstood .

also to imply that Stefan is allowing disruptive behavior here ...do to some suppressive agenda ??

very very inappropriate IMO.

I am not looking to derail this thread ,.....just this attempt at censorship [of AG]
and to be perfectly honest, I really don't understand his posts all the time either .

No stone left unturned ...

Just one mans opinion.

respectfully
Chet K
ps
perhaps another thread for these type of discussions [Censoring builders who share their work]]
most forums have "rantrooms or Discussion boards for these issues between members.
