I am very familiar with the false HIGH VOLTAGE claims of those ebay modules--I just saw a module rated at 1,000,000 V today! it's like the outrageous claims on the stun gun's millions of voltages--I guess a way to measure it yourself must be found to know what is going on--also the output waveform is strange.
--seems we were writing replies simultaneously here!
I measured mine and it turned out to be 9kV @ 6VDC input... not sure how accurate my meter is though (i made it by hand)
I bought a 250uA galvenometer with a range from 1 to 10... so i assumed 10 @ 250uA ... then I calculated what resistor I need for it.
(10kV @ 250uA)
edit:
I just sketched up up the components in a CAD program... I need help making a box for them...
edit 2:
this would make a nice chassis, but there is no room for parts... Maybe I can add a PVC pipe extension?

Working on prototype 003...
Waiting for power supply to come. The aim in this one is to minimize form factor.
P.S. The arc isn't hot enough to burn plastic tubing.
Can anyone help figure out the ideal form factor? I was thinking of using a 6V flashlight, the coil would go on it nicely, however, not enough room for the HV power source.

I would think twice about that spark being "safe" esp. over time. I have used those modules and they are bright and hot, even without the LC--there may be an internal "C" right at the output?? Do you know the makeup oh the high voltage module? I have tried long and hard to find the schema--I started on the 7kV modules.
Why not just use two air core -elevated- screws for the gap? JB weld will help with the details.
Even if the spark doesn't quickly burn the plastic it will over time.

P.S. ... I don't change my data, I post new data and leave the old there. I also describe anything that might throw it off.... prototype #3 i changed the capacitor value, but I posted about that too... I tried 5 turns with type 3 EMP with different capacitors and got the same range...
LOL... I accidentally electrocuted myself in the mouth today with 9kV, lol

"Electrocute" usually implies 'killed'
You can see a beautiful picture of the resonant frequency of the oscillation of any particular LC by energizing or DE-energizing the cap through the coil while hooked to an o'scope. As the amplitude drops, the frequency (resonant) remains constant on the scope and you can simply read the LC frequency or period.
BTW...an interesting experiment: Charge a disposable camera until the orange "ready" Ne lamp comes on, then zap it with your device--I bet it fires the strobe! May even work on a digital camera--if you have one to trash. My small laser flashlamp trigger fires them at a few inches.
You know this device would surely be illegal (if not already) if boosted!
