I'm not talking about preventing a circuit by using a diode, I have an ultrafire charger (for flashlights, well did have, hence this thread) i've had it for 2 years been very careful up to now, I wired up a cable works great and one day i was using the 12v out for something else so i used a couple of crocodile clips and connected up the positive / negative manually so i could charge it..
Almost instantly the thing died, I got a feeling the regulator had a fit and died because of it, the caps were not too happy either but they are fine, so anyway to prevent this from ever happening again on anything..
how about a circuit that sits between the device and the 12vdc (most of my stuff is 12vdc, so im not worried about about anything less than 5v) so what about some kind of circuit which detects the short and almost instantly cuts off supply to protect the circuit?.. this possible?
