Gray Tube Replication

Hi Pranav,

Looks nice and simple, thanks!

With 22uf on the front side, that is probably enough
that you don't need the diode (dotted line position).

You show you have an isolation transformer on the
front but I had problems even when using an isolation
transformer.

You could run one of the transformers from an inverter
connected to a battery.

Anyway, if it works without the dotted diode then
I wouldn't worry about it. I have done it with or without.

You mention the bridge with 1x3 diodes. Do you mean
you have 12 diodes for the full bridge? What are their
specs and what is the max voltage you are outputting
from the MOT when you turn up the variac?

circuit diagram

hi arron

i attached circuit diagram please check it

i made bridge with the 1x3 microwave diode i think this is the problem in my circuit

and one more think is while applying dotted diode circuit doesnt trigger

i dont understand why this happened

have wonderful day

Gray Tube Replication

You guys have been busy.

Pranav - it looks like you definitely got it!

Can you post a diagram?

Geotron - I'll have to look at all your posts soon, just been busy.

my test video

hi arron

i just test my circuit

circuit works very well

i solved a problem of power resister heating

but one new problem i am facing when i increase voltage amp goes very high it goes up to 19 amp i dont understand why it happened

i think it happened because of the bridge of MOT

i just purchase 16 amp 1200v diode

i am going to use it like to you

and one more think is when i connect lv to hv diode circuit doesn't
trigger

please check this video

The high voltage generated from the output of the ignition coil does
not seem to want to transform into plasma with the use of 1000V 1A diodes
in series. The previous blocking diode that broke on my ignition coil
was rated at 10mA, so it seems a nF capacitor would be in order next time
with such a rating.

The video previously shown in which a transformer was sparking backwards
a surprising amount is what I have learned can be due to either a faulty or
absent diode for the generation of a plasma burst. The LV capacitors
will not collide properly in the spark gap; rather on the coil sending
the HV burst from shorting a capacitor... also causing defective transistors.

charging up!

edit: The triac, as I've learned is being used in light dimmer knobs around the
world, and being a short-signal component will likely not provide the desired effect
of ac-transformation.

I'm seeing now that the way to go is with an inverter coupled with
voltage control for driving the LV side power supply transformer rather
than pulsed DC...

Aaron, you've clearly shown this in practice utilizing a variable
transformer to charge those caps, and it got me wondering if another
proper way of going about it might be with a household light-dimmer
knob. I'm sure that I would like to use a variac, only with the
relatively high cost of obtaining one it has sent me to look for
alternatives. Another possibility I'm considering is a power tool
speed control box, as is commonly produced for routers.

It has gone awry and done away with my ignition coil... I'm seeing that
with the 3rd point output connected directly to the (-)battery with a
short gap to ground that the entire discharge is being absorbed into it
rather than sparking across.

Amidst an experiment to see whether a PC fan connected to a separate 12v
battery may operate normally with the discharge output connected to the
(+) pole instead, some event took place that fused the coil together.

Anyway, initially the Run battery showed to be recovering energy from having
its (-) pole connected to ground, into which the radiant bursts were traveling,
then with the output going straight into it instead it was steadily losing
voltage.

Does it seem right that the output may be directed into the (+) pole
of a battery simultaniously powering timers and other delicate circuitry,
acting to condense it into useable charge while sustaining a proper
voltage to the electronic components?

I've taped a small demonstration video of my 2000ft spool of 25g wire bouncing
a couple of small neo magnets. The Lv side was being fed with about 500V from
a bank of five transistors pulsing 12V from a battery through a 100w transformer.

Much better results now with using a 12V motorcycle battery in place of
the 250w PC power supply - many more bursts per second, even though it is
a bit out of service from sitting too long and will not run an engine. Its
negative pole is connected to the output and also directly to ground, looking
like it may work even better instead with a gap onto ground, perhaps sealed
in a box.

The scr diode was not seeming to work with about 1.5V reaching its gate,
instead turning into negative voltage upon being connected by an interruptor.
It may be the datasheet is wrong... it shows a notch in the gate lead, and
the ones they sent me don't have any notches.

With a raised frequency at 50% duty cycle it has upped the LV side output
to over 700V. The way in which the percentage can be varied has me intrigued,
shown at Electronics in Meccano. The LV side capacitor voltage seems to
float around 150-200V when in operation at slow speed; 4-6 contacts per second.

Using a rewound center tapped transformer will be my eventual direction if PWM
and additional transistors are not sufficient. Thanks for your patience
in helping me along Aaron and others with this truly incredible energy...

With a leyden jar it seems to fan out from the anode and light up the wire
on its way through the copper lead connected to ground -

After a bit of changing things around it seems to be working now without frying anything up,
except one transistor out of my LV charger that is more than likely stuck open. I've added
3KV worth of diodes to the (-)output of the transistor and timer circuits in order to help
block anything from going backwards into them, as well as 3A fullwave rectifiers on the
transformer outputs.



Curiously at last measurement there was around 530V 3A DC being produced on
the LV side transformer from the bank of 5 transistors out of the 250W 12V power
supply, measured without a load. At this point it has returned about one burst
per second with 1/4 - 5/8ths gaps on the rods from three 250V 22uf capacitors.

I'll be reworking the transistor wiring to equally distribute flow between them,
but as for increasing the rate of discharges, my best ideas are to decrease the
spark gaps and use a thicker transformer.



HV plasma - top LV caps - left

The way it was showing up before, the transistors would heat up on one
coil while staying cool on another, while currently they are all now
generating nothing other than resistance leaving the coil to pick up
only a minor voltage. Metering shows the transformers to register on
the Ohms scale as they should; in any case this is the layout



also, the diode bridge was not being used

mot full bridge for hv side

Hmm... I had just attached a single 3A 1000V diode to the AC output,
then connected right on to the CDI caps without a resistor, as it had
been limited to 1.3A or so at 220V. The LV charger side with the 6V
wall-plug transformer was setup in the same way.

I'm glad to know it was just not enough diodes to block whatever
was attacking the coils... although with my lack of an immediate
replacement transformer I may try pulsing 12V directly though a
CW multiplier just to see how it goes. I'll definitely be loading
up the output with blocking diodes too - the punch of this thing
is amazing...

For you, it possibly might be the same issue. I just know that for me
using a full bridge from the high voltage side made of 8 x 6a 1000v
diodes did the trick. I hope it is that simple for you. I'd definitely use
a full bridge in either case.

bridge

Geotron,

I've fried a few mots myself.

What kind of bridge do you have leaving it?

When I had just a 1kv bridge made from four 6a100's,
I had problems even when I had the output like
500v or so.

But suddenly when I used eight 6a100's for a 2kv
bridge, the mot worked flawlessly.

It looks like the problem I was having did not have to do with the
transistors or other components.

I've just finished reconstructing it all nearly from the beginning, and
after unhooking the circuitry from ground have found that upon obtaining
the radiant burst -



- it is instead the transformers that are blowing out! Previously I
lost my LV-charger side, and upon rebuilding the HV plasma supply unhooked
the driver from the microwave transformer and connected it to the one
on the side that stopped working. It heated up the transistors and did
not produce a viable output voltage... after which I hooked it back on
to the m-wave transformer and it worked fine. The pics are from having
a 6v dc wall adapter on the LV side hooked to a CW multiplier feeding
a 2000v .7uf m-wave capacitor in place of the HID ballast transformer.

All of my transformers have now stopped working, except perhaps the ignition coil.

I'll could draw up a diagram of what I've got, but it is basically just
two transistor coil-driving circuits sharing a common signal input, each
hooked to a different transformer and everything sharing a common (-) return.

I'm having a hard time understanding this and how it may be fixed.
Upon firing up the bursts as shown above I noticed a definite (*clack*) sound
emitting from near the microwave transformer - quite loud, although it may
have been a strange reflection of sound from somewhere else. Anyway, unless
there's some way to fix what I've done to them I'll have to obtain new ones
or find another way of generating the 2-300V out of my 12V signal.

green plasma

Its about 6min 10sec through when you've disconnected the meter from
the battery bank and then pan over to the hanging series of diodes, that
wasn't connected. In your video showing the 3-point plasma outside the
tube, as well as the other - there's a definite 'flash' burst not present
in the 4-place recovery tape. This is the energy I'm curious about,
having it go on through the motor and pass into a (-) battery terminal
on its way to ground.

After seeing no damage to my grounded components after many a normal plasma
discharge from the ignition coil to ground, then having them utterly destroyed
by a single one of these Green-type plasmas, it gives me a good feeling about
its usefulness when properly harnessed.

Interesting, not sure why the 4 recovery vid doesn't show the green burst.
It is there in person. As long as an inductor is in series with the plasma
effect, it is green. Take away the inductor and it is more white.

For example:



It's actually really a pretty color.

I did countless tests to show the comparison with just the plasma and
no inductor with many different metals and then did a lot with inductors
and different metals. I showed conclusively that the green came as a
result from the inductor changing the properties of the plasma.

The reason I did these test was because so many people kept telling me
it was green from the copper but of course, they didn't do any of the
experiments.

Notice I have all the same metals - copper rods and copper grid for
both of the above. Normal plasma white with copper but just add inductor
and it is green with copper. So it isn't copper getting oxidized or whatever.

Someone in the water sparkplug thread said I created a "slow" plasma
by doing this. I haven't looked into it enough to see what this means.

I stumbled up on this by adding an inductor originally because I was trying
to restrict current at the plasma gap thinking that if I prevent more
electrons from getting in the gap that the plasma igniting water moisture
wouldn't have enough electrons to reassemble back to water and therefore
may give a real thermal explosion instead of it just imploding back on itself.

And the plasma was quiet. Notice you hear it, but it is muffled. If there
was no inductor, that plasma in the vids would all be white and VERY
VERY loud but instead, the rotor winding up is the loudest part.

I noticed immediately the inductor that I was using as a current limiting
choke (really a spool of wire) - was jumping with each pulse and that is
when the light went off. Whether it has anything to do with Gray, I can't
prove but in literal analogy his patent, I haven't seen anything else that
matches it.

Anyway, in the 4 recovery vid, the plasma would be greenish and I'm not
sure why the camera didn't capture it. The camera never does the light
or sound justice anyway.

I've been doing some experiments lately, not necessarily on this Gray
stuff, but it is related and I think I have simplified it greatly for builders.
I haven't had a lot of time outside of my main project but when I do,
I'll try to post some vids and pics or something.

If it makes you feel better, I've destroyed boxes of components in these
experiments including countless cheap harbor freight volt meters. lol

The timing was always the trickiest and next time, I want to use a
hall effect sensor instead of a reed relay switch or I might try opto.
That was a serious pain using that reed the way I did.
