Gray Tube Replication

[What The Flux]

Yes, that is the video that I made. Unfortunately, the colors on the sparks are very difficult to see in the video.

Aaron, I am very interested in the healing machine that you built. I have a sister that has muscular dystrophe and several other problems for which there is no known cure. Do you have any drawings/plans for this?

Martin,
Your video is great, but for those of us who are trying to follow along and replicate, could you make us a schematic of your circuit with supply voltages and component values? I know it's a pretty simple circuit, but it's not that easy trying to combine the video images with the limited description in your posts. Many thanks.

Certainly, I'll see if I can find a schematic program and draw it up.

[martin]

This is it. I hope someone can explain what it's doing.

Martin's sparks

This is it. I hope someone can explain what it's doing.

That's even simpler than I thought... but that's a good thing. It's very similar to my spark-maker, but I haven't looked at the effect of an earth ground.

Your carbon resistor isn't shown in your schematic. Is that on the LV side of the spark gap? Do you find is changes the spark at all?

I have my sparks pulsing at 100Hz, but I'm now trying to get a repeatable plasma effect.

Thanks for contributing to this group.

For some reason, the wrong schematic went. Ive sent the right one now. The carbon resistor made no difference. It originally was in the negative path going to the laser supply.

Here is how Tesla impulse driver that I found would work with Gray’s tube. It would produce short HV impulses just the way Aaron described it. And it perfectly fits in driving circuit of Grays motor.
Thyratron is the same diode just with more flexibility.

modern electronics fry Want to have unlimited Free Energy?

Help to develop the shortest possible pulse on the LV side of the spark gap, any source of DC will work on the HV side provided it has storage capacitors

I am starting to agree with this statement about shortest dc pulses. I believe this is probably why so many experimenters couldnt duplicate Tesla's precision work back in the 1800's and still today. The magic must be here. I think we need some discussion around developing the shortest dc pulse from the LV side

@mike

i like where your heading with that circuit

[nat1971a]

hmm after researching grays vacuum triode symbol in the patent it appears to be a half wave amplifier symbol.

Interestly I have also discovered that that vacuum tube that Tesla apparently used in his pierce arrow was a 70L7-Gt which i also discovered is a half wave/beam power amplifier

This also fits in nicely with the comments on the EVA4 motor being more powerful as it was also using half wave rectification

So it appears that perhaps half wave rectification is definitely the go if any one is looking at vacuum triodes

Here's an update on a new idea I had about the Tube. I looked at Gray's patent that shows the schematic of the floating flux field coil. I noticed that the motor windings are 90 degrees to the fff coil. Just out of curiosity, I wound 2 coils of wire around my cset tube (90 deg to the electrodes). One was clockwise 16 turns, the other counter clockwise 16 turns. Where the 2 coils meet in the middle of the tube, I connected those two ends to the cathode of the HV diode from the ignition coil. I tied the outer ends of the coils together and connected them to the charging capacitor. It not only raised the resonant frequency of the circuit to about 6 khz, but also doubled the output of the lamp attached to the cset. The spark gap actually hisses like Tesla says it should in some of his experiments. I get the normal 1 wire power transfer, but if I hook it up to the shield of a 50ft loop of RG6 coax I hung on the wall, it gets as bright as if you hooked it back to ground. I didnt think to try to adust the freq. while it was connected to the coax loop.

There is absolutely no arcing between the center electrodes and the grid. Getting the spark gap right is a real pain, but this is the most output that Ive ever been able to get out of the tube without any arcing to the grid.

you may want to try using coax for your floating flux field. In my experiments it traps the radiant energy in the wire otherwise it dissipates. Well done!!


i suspect it it coax on the ema4 motor

Great video !

Thanks Martin for sharing this important point

Does the Amperage on the power supply change when you connect the FFF, when the light become stronger ?
Is this FFF independent from the HV source?
Keep on the great work !

Just stumbled upon these, hope all of you have them:Photographs of Edwin Gray Pulse motor

Thank you freeukpower for your post and schematic
I guess that when your plastic tube was 2m long, the ball bearing had a lot of time to accelerate and gain speed. This way it hit the electrodes much faster and stronger, making a fast and strong contact. A question, did you use the rectifier negative as a ground or did you use a real earth ground? Also I see a problem in that schematic, because as the ball hits the electrodes, it discharges the cap, but is now also shorting the circuit out, so if your MOT is still runing at this time, ir can fry. Or did you just charge the cap fully with mains power, then disconnected the mains power and only then fired the cap? Or maybe you have a system where the ball bearing is just touching the electrodes when falling down, but the electrodes is just close enough to each other so that the ball bearing can fall through?
Anyway, excellent post. Can't wait for your progress
