I have a "working" flyback driver and I can get up to 2 inch sparks using a laptop charger that gives 16V @ 4.5A, the problem is that the laptop charger that I'm using for power keep dying. The first died and only gave 7.4V after and the second one showed no voltage after it died.
Here is a link to a simulation of the circuit I'm using. It's a basic NE555 driver. (LINK) The 1nH inductor in the simulation is one of the yokes from a TV.
I'm thinking of just adding a boatload of capacitors at the end of the charger to filter any voltage spiks, and maybe adding a diode too. Although it might also be the hi "pulsed" current draw that's killing them?
I don't know, so here I am asking for advice. How do I fix this? Because I don't want to have to keep replacing the power supply every 10 minutes :tired:
