Don't know if I'm being reduntant, but I reccomend them anyway.

My small group of friends is currently making a flyback transformer hooked up to a small prod. This think can get you 30kv at 1 or 2 milliamps, when finished, it will send static sparks up to six inches through the air.

Also on the list is a negative ion vortex gun. Basically it fires a donut-shaped blast of negatively ionized air at a range of about 100 ft. Not capable of doing permanent damage (unless you put your head right next to it, in which case, kiss your eardrums goodbye) but when it hits a person or group of people, it gives them a really bad case of static cling! The more powerful vortex generators can knock a 747 out of the sky.

6 inch sparks from 30kV? Are you sure about the output? A 30kV pulsed output may get you around an inch, but no way 6.

The link has been posted before, it's a great site. I wish I could afford that kind of equipment :-(

30kv is the output of the flyback I've got, hooked up to two or three large capacitors, and the power jumps quite a bit.

I'm still not convinced that a cap discharge would go 6 inches at 30kV. Are you using a multiplier configuration?

6 inches = cca 15 cm, and a spark of 15 cm can be generated in air only by 150 KV*, so 30 kv is pretty insuficient for this spark (my oppinion).


*Note for keVVLz : 150.000 V

Actually it's 150 000V or 150,000V

150.000 = 150V http://theforum.virtualave.net/ubb/smilies/smile.gif

a cap discharge at 30kv will go further then 6inch - in ideal conditions of course. however 6 inches is quite easily obtained in normal conditions.

I always thought the general rule of thumb was that 10,000volts would arc 1 cm.
30kv would only be 3cm at best .
correct me if im wrong.

Yes Anthony, you are right, but in my country the 'separator' for numbers (thousands groups) is '.', not the "," .

Is important that you get the idea : one hundred and fifty thousands volts. And I hope that everyone http://theforum.virtualave.net/ubb/smilies/smile.gif

I still believe that in dried air, with pulses of 10,000 volts (not high frequency as Tesla Coil's discharges) the spark lenght will be no more that 10 mm.

30kV WILL NOT cause a breakdown 6" long in air at RTP. Corona discharge = *maybe*, from a VERY sharp point. Unless of course you use a UHT trigger of about 150kV, like in a big flashlamp.

I fired the thing up this weekend. Oh my lord, I got the 6 in spark I wanted (spark gap set to 6 in.) but I doubt I'd get those kind of results under anything but lab conditions. Doesn't matter, it'll be used to power my 'galactic donut gun' in a few months.
