Thanks jmartis. What kind of voltage? I have a 10,000uf 35v High-ripple, will that do? Will the HV spikes not damage that, I wouldnt want that to explode! Safe to build it into my box? Also, is it correct that I should ground one half of the secondary? Won't that put HV into my 12v negative?
Thank you!
Of course the capacitor must be higher voltage than your power supply, but doesn't have to be much higher. Your cap will certainly do it. Ground the negative secondary output to mains ground.

Hey I was using a 5-7amp 13.8v psu to run my flyback, but last night while messing with it, the arc halfed in size, then 2 seconds later, a capacitor exploded in the psu. It was a small 47uf 16v electrolytic. I have replaced with a 47uf 35v. My question is, how can I stop these high voltage spikes going back into the psu? Maybe wrap the + and - 12v wires in two ferrite rings like you would use for RF, or would that not work. I have also been using a 12v 7AH Gel cell, any fear of that exploding?!
2 neon bulbs in series over ( I think ) the base of the main drive transitor to the collector. there are 2x 3055 under there

Is this flyback suitable?
