Hi Guys, could somebody help me out with this one please. (I've attached the schematics)
The circuit works great and the cameras trigger etc etc so that end of it I think is sorted out.(Provided battery is connected up correctly-of course)
What I've noticed is that the LM393N quickly burns out (and I mean really hot!!!) if the 9V battery is connected up the wrong way round for a brief moment. After that the LM393N POWER PIN (8) and Ground PIN (4) are dead shorted.
Is there a simple way of protecting against a reverse polarity connection without adding too many components as I am limited for space.
Could I also take this opportunity to wish all you guys in the USA luck with Hurricane Sandy. I hope all works out good for you.
Thanks - JDR04
