I just feel like since he's using 24mF total in his caps, even 4.7k ohms would still allow a ton of current to blow through the charging circuit and fry the contacts on the switch. I unfortunately only have relatively small momentary switches at my disposal, and have had this happen on more than one occasion with smaller designs. The idea is to get this working then swap out the caps for a much bigger bank I made, so i'll need to get the trigger isolated a bit more first. Would an optoisolator work? | |
