Hid Ballast as a spark generator

Unread postAuthor: striker » Tue Dec 04, 2012 2:03 am

Just wondering if any one has used a HID Ballast instead of a coil or other as a spark generator? Looking at other options and ideas

No idea what you were talking about so I looked it up: http://www.blindinghid.com/what-are-ballasts/

Doesn't sound like the sort of thing that is going to provide the high voltage needed to arc through a spark gap...

Im more interested in the start up "strike" voltage- im told its up around the 23kv mark then drops back to 85-150volts to maintain the light,

If it doesn't burn the thing out and that's the voltage output, could be worth a try... also, would you need to carry a 12 volt car battery around with you?

There's a lot better options around than HID ballasts, they don't offer much current on the strike voltage, and it's only a quick pulse. Ignition coils driven with a vibrator are far better.


Don't even start Jack, it's a relay set up to oscilate

hehe recently I had to create some documentation for the qualification and operation something similar to this: http://sturtevantinc.com/micronizer.php

The hopper has a vibrator motor agitating it, I spent ages wondering what to call it in order not to give the plant operators something to chuckle about but in the end there was not much else to refer to it as... and how we laughed! :roll:

hi, i came across this topic regarding using a hid light ballast to generate a spark. i know nothing at all about electrics, so thats why i use it LOL! i might add it is not been used on a projectile throwing pipe thingy :) i admit i have burned a couple out, until i found it does not like earths through the body of the ballast so i have wrapped in silicone tape. it will provide a constant arc (depends on type of ballast?) or a regular spark via a flasher unit/bulb for a resistor/and a relay to power the ballast on and off.it does not like normal resistor spark plugs. anything else is good. with a constant arc (depending on gap) the electrodes will glow white hot. regards jon
