The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I want to build an ozone generator but therefor I need high voltage. In this plan: ozone generator (I'm not interested in growing marijuana, it's just the only plan I found) it is written that you can use transformers from neon signs. Are the ballasts meant? I always thought, that they just put out a high voltage to start the lamp and then run on usual voltage... Does it work this way or not? Can I use such a ballast for getting constant high voltage?

I think the best and simple ozone generator would be a flyback transformer with a simple driver circuit. Adjust the output electrodes as close as possible without starting an arc, there will be corona between the electrodes which generates a lot of ozone depending on output voltage.

to find which prong on the bottom is the 'ground', hook up the flyback to a driver and wind 3-10 (roughly) turns around the exposed iron core. when it is on, move the thick red wire with the 'suction cup' near one of the pins on the bottom. you will hear or see arcing / corona to one of the pins (or a few).
if you dont have a driver built for fylback, there are many floating around the internets. be friends with google. there are a few simple and complex ones here:

If I wanted lots of ozone fast and didnt need portability, I would just use an old NST connected to two pieces of window screen on either side of a piece of plate glass. No ballasting is needed as NST are current-limited. And even if they weren't you'd be fine if you were careful to avoid letting an arc form.
A flyback driver is much more controllable, though. And when you are done there's plenty of other things you can do with it.
Ok, I understand it this way: I build a driver circuit like this: click here and then connect the two lowest red-marked pins with A and B (Feedback) and the other two red-marked ones with C and D (Primary). Then I connect it to a 24 V DC power source and move the thick red wire (with the round rubber) over the small pins. Where the arc comes this is the ground then. Am I right?

i have never used the 'built in' primary that is in the flyback transformer. i usually just wrap turns of insulated wire around the exposed iron core. i recommend doing that.
this picture is of my old flyback that shows how i wound the primary windings for a different circuit. underneath the giant forest of electrical tape in the picture is the iron core where you can wrap the said amount onto (read the instructions on aaroncake. com for number of turns).
these things produce a heck of a lot of ozone, which made me sort of sick. haha but that was with high power (something like 300watt) but that circuit you linked should be suitable for what you are planning.
