This site has the ZVS schematics and explanation:
There are many tips in the forum, but it is not accessible anymore, fortunately it is archived:
To discover the Flyback pinout find this tutorial:
I need to create a high voltage circuit to implement an electrostatic painting. It will be used to coat a virgin PCB with photosensible ink.
Update: I will start with a more simple and less powerful driver using the CI 555 : http://www.eleccircuit.com/efficient-flyback-driver-circuit-by-ic-555-irf510/. These ZVS are ways over the lethal current (10mA) your heart will support.
