Dons got it here. These things are so cheap now, its not worth it IMO to build one. Plus its got the reostat for dosage control.
0 Agios,
Yes a Jacobs ladder will create some ozone, but regular corona discharge will produce more. be real careful with the flybacks- they can put out a lot of power. All the DIYs I've made are UV or with a neon transformer that is power limited to 200mA or so.
Giovanni,
I tried to use a flourescent lamp ballast once, but the open circuit voltage was only 600V. IME, you need at least 5kV to make ozone. HTH
For Johnathan, et.al.;
O3 can be made by corona discharge (high voltage- dont need an actual arc), or UV in the 185nM peak. So you would be swapping your 253nm lamp to a 185nm lamp. UV produces less O3 per watt, but since its glass, doesnt need the air dryers that CD units do (CD parts corrode)
Basically corona is produced by a high voltage electrode, ground electrode, and a strong dielectic (glass is best, acrylic works OK) between them.
The high potential of the electrode wants to jump to ground, but it cant due to the dielectric. The resulting field is called corona.
The corona cracks some O2 molecules into O1s, then the VERY unstable O1s reattach to some of the O2s, creating O3- also very unstable and the reason O3 has to be created point-of-use.
If you use very low doses, no carbon is needed, as it will react immediately and be consumed. If you smell ozone (you'll know- its a sharp smell) then you need to turn it down or use WET carbon to destruct it. (ozone reacts with dry carbon and forms heat- or so I'm told, but havent seen it personally)
Ozone is good at killing odors (oxidation), but will give you a headache in larger doses. I have run quite a few large ozone machines at water plants, public aquarium, and even a smaller unit on a trash compactor. I got gassed bad by the compactor unit once- really opened up my nose and throat and I coughed for an hour.
I do run a UV ozone unit in my HVAC at home. I dont mind it, but my wife doesnt like the smell. Sometimes I'll run it on a timer when we leave. Smells nice and fresh upon returning home.
Sorry for the random rambling...

is oxygen with one more atom, anyway the devise and release or all ozone will be outdoors. My setup has the pumps and sump outside.
