Kapanadze Cousin - DALLY FREE ENERGY

[Hoppy]

hi TinselKoala,

I have already given up in trying to teach an old dog new tricks.Maybe you would have better luck with the intention help someone not to use a Mazilli circuit which i have mentioned few times before it is a pain to tune the frequency.

The SG3525AN is a better PWM generator than a TL494.The source-sink is around 450mA for SG2525AN but for TL494 it's mere 200mA.

Some people prefer to learn the hard way!

I too favour the SG3525 over the TL494 although I prefer not to drive mosfets direct from its outputs but it can be done as you point out.

   The 1.7Mhz of the Kacher must some how be in sync up with the 37.5 meter 168 turns grenade output coil, as well as with the grenade inductor (resonator) coil.
  Does any one have a signal generator, and a 168 turns, 37.5 meter grenade coil built up, that can test the self resonant frequency of the coil?

  I added some turns back onto my Kacher secondary coil. But, I still just a have 1mm spark, and no streaming.
  I'll take some new scope shots, soon. I didn't like the ones that i just took.

Does that mean that TK will then fund the parts for all the benches out there?

Does that mean that you lot are going to start paying me for all the valuable consulting services I'm doing for you?

Don't hold your breath. Try being nice to those who are helping you. If you think you can do effective work in this area without those four items of test equipment, go for it.

...and more advanced workbench?
VNA? LRC bridge? RF wideband analog amp?

Sure, those are nice to have if you need them. I'd put a frequency counter of some kind and a plain old spectrum analyzer ahead of those though. Oh... let's not forget a _calculator_.

   TK:
   Yes, those 4 things would be nice to have.  Someday, one step at a time. But, like yourself, I don't have much room.

   The difference of using the same fets, and changing a few snubber components to match what the TL494 board requires, does not sound like mayor surgery.
  Does it matter if the Mazilli becomes something other than a Mazilli circuit?  No, not to me.  However, I'd still like to see what the Mazilli/yoke/grenade/Kacher combo that I've been working on can do, at resonance. So, that's the plan, for now.
And, it's good practice, resonance sniffing...  but, I think that I should also try to replicate Ruslan's same running frequencies, to see if I get any effect there. As he has already found them (those resonant points), for his device. And, it's the same 168 turns grenade coil, and 37.5m ground line that I'm using, or similar.
Except for my 12,12 turns bifilar induction coil, which may need a new rewind, or,  maybe not.
I can also still remove another turn off of my 4 turns coil, and have just 3 turns, if needed to tune that circuit.
 
   At these prices for the ZVS drivers, $12,  it makes me wonder why I even bother to build the Mazilli. There's different models, also.

Take a close look at that ZVS board, and the different models, and note carefully what you see. You are _already using_ the circuit found on that board. The main difference is that the board is laid out properly and so will probably be more stable and less likely to destroy components. For 12 dollars it's only a little more expensive than you'd spend on the components to build your own.
