to start off this is my 2nd thread on this forum. i would like to restate that i am very experienced with high voltage, you can check my site in my profile. i came across a cool project that i would like to duplicate but also make a little better. here : https://www.youtube.com/watch?v=q0MbY0w8F3o is a video of a guy that charged up a couple microwave oven caps and discharged them through an ignition coil. i have all the parts. what im wondering is if there is a way to make it free running, similar to a marx generator. im thinking about using a spark gap that fires at a certain voltage, recharges the cap and fires again. i would like some input from other more experienced high voltage enthusiasts if they have any input or ideas on this. thank you.
