Itsu:
I don't know what you mean by, that there is something wrong with the scope shot of the traces, that I should be able to figure out. Do you mean with the voltage readings?

Yes,  like Void mentioned too, those voltage values (data) do not add up when you are using 24V input.
Also look at the CH2 ground (0) level indicator (the blue 2 marker on the left), it is in the middle of the square wave amplitude, it should be on the bottom like CH1.
Did you have your probe ground lead connected securely?

The main problem is that all the different resistors I've tried get smoking hot in less than one minute. That is a big problem, which I don't have a solution for.
Even the 5 watt resistor for the Oleg snubber gets hot.

My 2W 1K Oleg snubber also gets hot (80°C) when using a small load on the grenade (40 - 100W bulb), it gets better (lower temp.) when adding load, like 200 - 400W bulbs.
Also the input current drops when adding load.


Quote
So, it's not that I don't want to use the snubbers, it's that they all go up in smoke. Even with a smaller load on, but especially with 200 to 400w worth of bulbs on.
In any case I'll figure out what to do about it, I'm just reporting back what I'm seeing. But, what I mean is that the snubbers ARE needed.
But, they have to be kept at use able temperatures, or they won't do they're job.

I thought you mention that you do not see the "effect" when using snubbers, or much less, so therefor i said that you have a problem with which i cannot help you with as without snubbers you will fry your MOSFETs.   Only some higher voltage rated ones will probably work.

 
Quote
My smaller 1/2 watt resistors (like yours) were chard, in less than one minute. So, maybe there has to be a compromise, somewhere, as I've always had some kind of heat issue,
with either the fets, or the snubbers resistors. 
Possibly the carbon resistors don't come in the bigger than 2 watt values. But, not sure about that.
Any way, I'm just reporting back. I know that you may not be able to help me any further on this problem. That's ok.
I appreciate your help.

My ½w RC snubber resistors are not heating up, not with a small load (40W), not with heavy load (400W), but they have higher ohmic values (170 Ohm) then yours (46 Ohm).
It could be that you need to re-measure your ringing signal with your new scope (without any snubber components), it could be that we end up with some higher valued  resistors which would have less current (and heat) going through them.

Finally, i also have a varistor across each drain / source, it could be that those have a limiting effect on the spike so the RC resistors are doing less work.
Perhaps you could install your varistor (14D271K , see  http://overunity.com/12736/kapanadze-cousin-dally-free-energy/msg509339/#msg509339) again across each drain source.

  David:
  The fishing line idea has been tried on the Kacher's secondary coil. But it does not need to be 2MHz, as 1Mhz to 1.7 or 1.8MHz is normally high enough. Mine is running at 1.1MHz.


 
   The second pic is from Stalker, and is what his best fet signals look like. His peaks go from 238v to 262 volts.
 
I think Dave is trying to keep his device as slim as he can if his Katcher is using 5 or 6 mm cable  and he winds T1000s charger winding it will be huge in diameter so I think he is using 1mm copper and packing the 5mm or 4mm (whatever) with fishing line must be a hell of a job winding it is all I can say.

Have any of you guys ever got in volved with transmitters you know a load coil and the tuned aerial length, ? ever touched one when some one is transmitting?  fun ain it ;)

  Itsu: I could not obtain the needed 43 or 47 ohm 2 or 3 watt carbon resistors for the snubbers. So, I'll try to order any resistors that are 47 ohm, and 1k ohm, and see how they do.

Notice the difference in Stalkers scope shot his ringing is in the dead zone !

I couldn't get my Katcher to run under load at much above 1.3 Mhz never lone 1.80 Mhz until I bifilar wound the main 19m coil 1mm copper and 0.6 fishing line ;)

If some of you remember, back in 2014 Ruslan did a demonstration video where he
was charging I think maybe between 1 to 2 uF total capacitance to around 1000V using only
a kacher circuit driving his tesla coil and the output of the grenade to charge the capacitor.
According to Ruslan, using some sort of special pulsing circuit at the output and a specially
wound output transformer, Ruslan was able to power over 200W of light bulbs, plus power the
kacher circuit in self looped run mode. So, if that video was legit, then that means that you
should be able to get over unity just using the kacher with no PWM. However, as T-1000
mentioned in a previous post, we would need to figure out what he was doing in that
specially wound output transformer he said he was using. Could it be that unless you
know the trick of how to take the output power off of these type of setups that you
will never see OU? If that is the case, then it means we are missing something
important in regards to how to take the output power off the grenade winding.

For comparison, I used a flyback driver to charge a 0.91 uF PIO capacitor to 2.96kV
with a sparkgap across the capacitor adjusted to discharge the capacitor about once
a second.  It was interesting that with this configuration the capacitor charge rate was fairly
linear, which is not normal for a capacitor. The input current from the battery would slowly
increase from 0.6A to 0.8A as the capacitor was charging, so I think that explains the fairly
linear cap charge rate.

Taking 0.7A as the average input current, the input power to this setup was:
Input Power = 12.8V x 0.7A = 8.96W

You can see in the attached scope shot that the 0.91uF (measured) capacitor was charging
to about 2.96kV in about 1.1 seconds. I was using a 1000x high voltage scope probe on
the capacitor.
2.96kV on a 0.91uF cap is 3.987J
A charge time of 1.1 seconds gives an ouput power of:
Output Power: 3.987J / 1.1s = 3.62W

That's an efficiency of only about 40%, although I suspect that charging around 1uF
using a kacher and grenade winding like Ruslan did may not give very much better
performance, as I think the kacher circuit using a 12V battery draws more input
power than the flyback circuit I was using. If anyone has a kacher setup and grenade winding,
if you want to compare cap charge performance to my test, (input power, charge voltage, and
charge time), I would be interested to hear your results for comparison. T-1000, are you able
to try this test for comparison?

I see two possibilities here if Ruslan's video was legit:
1) We may need to have a specially wound output transformer or other special method
to take the output power off the grenade, otherwise far from OU.
2) Maybe only people who live in certain areas with special earth ground characteristics
can have a chance of seeing OU from these types of setups. If that is true, then
if you live in a area with the wrong earth ground characteristics, then you may
never see OU from these setups no matter what you try. I don't know if that is the case
however, but it is something to consider. :)

If no one is able to try this with a kacher and grenade winding for comparison, then
maybe I will set that up when I get the chance and try it for performance comparison purposes. :)

When you directly charge capacitor from the HV output it will be always similar to this case. But the case we are after is, - when the the capacitor is in near field (ref - Tesla Ambient Receiver patent - http://www.nuenergy.org/uploads/radiantenergy.gif ) and the charge of capacitor is from the ambient source and the the main power source is not used on that moment.
I may suggest try place scope leads near Tesla coil and to the cap with voltage divider between cap and ground. Then see if you get that effect happening at certain voltages and frequencies of the Tesla coil. Myself still in middle of that process so cannot tell definite results at the moment.

Cheers!

                                                                                   end quote.

   Itsu: I'll install the 271 varistors back onto the drain/source and see how it goes. They were working pretty well by themselves  before, when I thought they were a blue HV capacitor instead. If I can keep the peaks from going over 225v, I think that it will be ok. As the current heating of snubber resistors or the fets is probably due to the over 200v peaks, I believe.

Hi T-1000. Yes, OK, when I get a chance I will try working with a tesla coil and grenade winding setup
to see how things compare in performance. This may be a good way to adjust the tuning of the tesla coil
for optimum performance. A tuning with the fastest cap charge time and highest efficiency may well
be where you want to tune, even if that alone is still not OU.
All the best...

   Void and Itsu:
   Thanks for the tip about the voltages. I guess that when ever I press the AUTO button, it changes the setting back to default voltages.  So, I just needed to change it back to where it was. I was focusing on the frequency readings and didn't see that the voltages had changed.

   Itsu:  I've made some orders to Mouser.com. But, won't get the resistors, and other components until after the 22nd of Sept.
   But, there are no bigger wattage value carbon resistors there, over the 1/2 watt size. So I ordered several of the 47 ohm, and 1k ohm, of the 1/2 watt size. Maybe they can be added together in series, or parallel placements.

WooHoo!

Did that scope finally find you Nick?


Hey, something to think about with y'alls yoke cores...

Square ferrite.  If you don't know what that means, watch this video
https://www.youtube.com/watch?v=p7SkE5pERtA

I recall seeing those waveforms on Ruslan's scope and wasn't able to
relate it to something I was familiar with.  Now I recognize it.

Yes, I think this is where Ruslan was monitoring the current waveform in the series resonant yoke winding by using a small toroid core, allowed to saturate by virtue of the high series current and sufficient ampere turns. The sharpness and amplitude of the 'moustache' shaped waveform spikes give a good indication of approaching resonance.

Oh! well done. I have heard it said that the 'cores; are originally barium based military grade that has been originally used, so to try and say what device to look for in the core material in the data sheet and how to set it up, I wish you all luck.

PS I used your fishing line air gap with good results thanks very much for that one ;) .

   Dog-One:
   Yes, it finally came!!!  I had to make an all day trip to pick it up at customs, they only charged 20 dollars at customs. They thought that it was a new scope still in the original box. I had to convince they that it was not new. When it was.
   It made it here in perfect condition.  I had made a post to you here on the forum when I got it, but I guess that you didn't see it.
   Thank so much again, Dog-One.

   Itsu: I been playing around with different snubber caps and resistors, and have managed to drop the peaks a bit, as well as the heat on the snubber resistors, and also the fets are staying somewhat cooler now.
   I also added a 0.1uf WIMA cap in parallel onto the grenade's output coil, which had not been used lately. This helped to reduce the high peaks, and mellow out the heat issue.
   I always use a magnetite magnet onto the ferrite yoke core, to fine tune the device with. And have always done so.
 
   As we don't really have any proper tuning instruction, perhaps I can show how to go about it, once I learn the ropes.

   Using both scopes, and a CT on the 3t induction circuit, I adjust for the maximum output from the small CT torroid, but it usually is not where the best output at the bulbs is at. So, I'm hoping that the Kacher's HV will make up for the difference, and will allow the device to receive Radio Moscow, again. As it's gotten a bit harder to find, when dropping the voltages under 200v.

Oh! well done now try telling them what to look for in the core material in the data sheet and or how to set it up, I wish you luck.

I don't do any "telling" around here.  Only suggesting what single ingredient may be part of the special sauce.

If reminance (sp?) is part of this equation, tiny soft iron shims between the yoke core halves may also be
helpful.

I do remember that "moustache wave" Ruslan showed us which means the core is being pushed into saturation
where the flux locks in a particular polarity.  I know first hand, efficiently transferring a nice normal sine wave
of current into the inductor coil doesn't seem to fit the bill.  I beat that dead horse well below ground level.

I think Nick is pouring some serious current into his yoke, so he may be hitting the saturation
range, but if the flux isn't locking, it may not matter.  Just want Nick to have all the possible
options laid out there for him, because unlike most everyone else, eventually Nick will try them.
Which is why Nick will get this thing working at some point.  He's serious and in the end, that's
all that matters.


PS i used your fishing line air gap thanks very much ;) .

IT does raise the frequency for sure, but it's very tough to gauge just the right size you need
so the frequency falls where you want it to.

I recall that I could only get the 'effect' with one of the mosfets running hot, which is why I deduced that the 'effect' was dependant on a chaotic condition brought on by mosfet avalanche.

Indeed Dog. Nick's dogged approach gives him the best chance of success. If OU is out there, Nick will discover it.
