Gray Tube Replication

Well I can tell you that the more capacitors you have (series or parallel), the more inductance there is in any situation.

Capacitance

Dear Mr. Ghst.

You seem to totally understand these capacitance roles.
Pherhaps you can answer my next question?

Situation 1. is 1000 volts stored into one capacitor.
Situation 2. is 1000 volts stored into more then one capacitor connected in series.

The total capacitance of both is equal and thus both examples cointain exactly the same amount of energy.

Yet....there is a diffrence when used in spark discharge circuits.

Why?

Circuit is variation of my original silent plasma circuit.

The cap bank is 1200v/50uf or so with 6 in series.
It is MUCH better at 2uf and there is no apparent
increase in power with higher capacitance.

CAPACITORS IN SERIES AND PARALLEL

Capacitors may be connected in series or in parallel to obtain a resultant value which may be either the sum of the individual values (in parallel) or a value less than that of the smallest capacitance (in series)

Placing capacitors in series basically you can add the voltage value of all the caps in series, the capacitance (uF) is the value of the lowest cap in the series (or less)

Parallel caps increase the capacitance (uF) by adding the capacitance values of the individual capacitors. But the voltage value will not increase.

Measure



You can use a meter like this one in the picture, to measure if it is radioactive.

Ah ok thanx. Its probably that.

Photo thing

Okay well in that case it can be the gas filled trigger tube.
Please be carefull with it because some of those contain radioactive material and gas.
If you brake it the gas can escape.

The component looks like a large neon, but in the inside it has 2 copper leads going to 2 seperate ?carbon like? arc points which are cylindrical. Around the circumference of the tube is wrapped a silver foil strip with one wire leading off from it. This wire leads to another component of which I do not know the use of. Maybe a coil? This component has not been seen to glow or arc at any point of the circuit's operation and stays cold.

Its not the neon either
I already took that off as well
Check the description ^^, its similar to a neon only because it's encased in a similar tube.

Flash circuit

Yes that is an old style flash circuit.
That small neon starts to glow orange when the flash capacitor is fully charged.
It's just an indicator to show you can take a picture.

In newer circuits a led is used.

The component

No its not the xenon, I took that off the board a long time ago. This part is soldered right onto the board. Here's some quick pics I just took now, what do you think I should do with it? maybe desolder it?

Paradox

Hi Paradox

Can you post a picture?
Are you sure it's not the Xenon Flashtube itself?

Gray-Tube like component

Yesterday I was about to salvage a transformer of a very old camera flash circuit (~1970) when I noticed a very strange component on the board. It looks like a large neon bulb, but bears all the hallmarks of a Gray Tube.

The component looks like a large neon, but in the inside it has 2 copper leads going to 2 seperate ?carbon like? arc points which are cylindrical. Around the circumference of the tube is wrapped a silver foil strip with one wire leading off from it. This wire leads to another component of which I do not know the use of. Maybe a coil? This component has not been seen to glow or arc at any point of the circuit's operation and stays cold.

Would it be appropriate for me to post more about it here, or start a new thread?

Size caps.

Utilizing the concepts of the Gray Tube, phenomenal power can be had with only a 2uf capacitor. I would really encourage experimenters to not go overboard with the size of the caps because the capacitance isn't where it's at according to my tests.

Hi Aaron

Your findings are correct.
In the light of the effect, the sharpness of the gradient, and voltage is what does the trick.

However,you can trigger much more discharges from a bigger cap before the voltage goes to low as to jump the gap.(many more)
So there might not be an increase in power, you can run the circuit longer on one charged cap.

This brings me to Capacitors in series.
My tests have shown a decrease in performance when i used capacitors in series.
Im not sure how you compared your capacitor/series tests but mine always showed less "pressure" when capacitors in series were used.

Capacitors

Hello Spokane

I got those capacitors from some dump shop.
The guy only had 3 and i took them all 3.( i needed 3 )
Prize was 25 euro each so i don't know if it's expensive but i took them anyway.
You can find High Voltage capacitors if you look for it...
