Nick,

I went back over posts and realised that I did miss the actual oscillator circuit which is given in post 2888. If Geo could re-post the full circuit giving full main trafo coil winding details and core dimensions etc., I am prepared to do a replication. I would like to know why on the video, his cap bank wires appear to be just poked into the copper heat sink / wire inter-connecting copper bars without solder or screw clamp connections! I would also like to know the voltage rating of his zener diodes which is not shown on the circuit schematic.

Dear Hoppy.

Is this the one you are looking for ??

Cheers Grum.

Oh, Grumage hero

And gotta be fresh on the fight "

I also noticed that Geo's RMG schematic shows a Royer oscillator, whilst his post no.2888 shows a Mazillii oscillator was used for the RMG. This is probably just an error on the schematic and a Mazillii oscillator was in fact used. Please confirm Geo.

Take a look at this: We've another smart ass who recons he's figured Kapanadze out (Like Tito) and he gives hints but no device.
Maybe putting the 2 together we can figure it out.

Take a very close look at the 'green box' video 4 between time stamps 09:11 & 09:48 for a good clue as to how Kapanadze did it. In particular watch the women as the bearded guy walks away towards the house with the 'kit' and look very closely at his left shoe.

  Hoppy:
   Yes, Geo is using a Mazilli crt with the IRFP250N and 260, without the zeners, although still is using some diodes in their place, which he says that also help to keep the heat down.  He did upload the Mazilli diagram (also) as being the way to go on this.
  The coil windings are fairly clearly marked on his diagram. The bifilar coil wound on the pipe (first) in two 100 turn layers, and the 80 turn output coil centered on top of the bifilar, with the third tuning coil and tuning caps on top the output coil. The video also shows how and where these ferrite pieces are placed. His crt is running on 24v. and is almost as bright as grid source. Although I don't see that kind of brightness in the video.
What is not mentioned is the size of the pvc pipe former, which I would guess is about 3/4" to 1" pvc pipe.  The pieces of ferrite are like the one that he is holding in his hand (in the video) from a flyback core about 3/4 inch long, with about 1/2 inch or so inch spacings between them. He says that the spacing is also important to maximize the output.
  I didn't use solid wire, as I can't find that either, and my circuit still works ok, when using it on the yoke core.

  Igors Royer/Mazilli circuit oscillator is a bit different. He is using the white ceramic resistors (wire wound), possibly about 0.5 ohm (maybe 3 to 5 watt), instead. And just a single LC cap, no zeners, but, does use the bigger diodes, and a 4 diode full bridge rectifier circuit.

  I overheated my 1 watt 470 ohm resistors when connecting them to 24v, which burnt my smaller IRF510 fets, and small 12v zeners. It may be best to use white ceramic resistors even if they may affect the crt inductance. 

  Using the RIGHT right value tuning caps for this purpose is also a very important part to maximize the output, and also to possibly help to keep the heating of the choke, fets, and resistors down to useable levels. They may be of different values, depending on the circuit for best resonance, and output gain.
  I also use the magnetite magnets on top my yoke core, which do help quite a bit, as far as to tune the frequency, and adjust the ringing noise to bearable levels.

   Here is Geo's first RMG video (below), again, in case some of us missed it before.
   He is going to show some input/output readings soon as well, now that he has a new meter, which can read amps. At least we hope so...

  Hoppy:
  I made some edits and corrections to my last post.
  I do agree about the bulb brightness being less than grid source lumin levels.
The brightness is somewhat similar to what I'm getting on my Mazilli/yoke set up now, when using just three 100 watt bulbs. But, with just a single 100 watt bulb, it's quite bright.

  Lets not get hung up on the brightness comparison, but focus on the feed-back path, instead.

Hi Guyz

Hoppy:

Alright, Yes I know ppl been asking for the dimension of the pvc. I've been using PVC of 2.5cm Diameter , thinking 3cm one would do too.
The wire gauges might be bit different, but try to Improvise, Try to experiment too. Just as how I did.
Btw about the brightness comparisons and all that, leave it aside for now. as it is irrelevant for me now.
But I will say the lights are Fairly bright at night and they help . Be happy what you have is the best thing.
Yes it's best to get the most output out of it, Brightness will increase while Stepping it up. But the main focus is really to feed the system back . Don't wrry, you can measure this one with Meters, it's not the same as how a Spark gap Generator works, where meters get influenced. tried it already. It's different.
Be patient, Otherwise try to Experiment with these examples I gave, don't be radical against just like that, it wont help friend. I told many times in the forum, everyone who is willing should try to replicate and experiment with it, sins it has alot of potential. I really need ppl around that do and not just talk. If you know what I am trying to say


Nick:

Yes Mazilli/Royer circuit is used on the RMG see the pic below, that one is used. With zeners, Zeners are needed. But I have tried various ways with other Diodes that can replace them and work well.
But there is something that needs to be carefully studied when the system works, at the input and output.
That will be shown in a vid soon.

Thanks for the additional info requested. There are still a couple of points that require clarification: -

You state on your schematic that solid wire, not stranded should be used where shown to avoid smoked / carbonised mosfets. This makes no sense to me. Please elaborate.
Why do your connections appear not to be soldered  /properly terminated to the copper strips. Is this deliberate and if so why?

If you wish people to replicate your setup, then its important to establish an agreed measuring regime. Brightness of bulbs and expressions such as 'massive output' are meaningless without measurements. Show us a measuring regime and results for your RMG and perhaps then a few competent builders will have a go at replicating against some performance benchmarks. With respect, as 'special' as you setup might be, it will not motivate me to replicate without seeing a more scientific approach to your demonstrations and that must include appropriate measurement and ideally waveform displays (I'm assuming that you have an O- scope). This will enable one to determine if there appears to be anything 'special' that warrants time spent on replication. As I have said before, at present I see nothing special from just viewing your videos.
