    Default Simplified circuit

    If all you need is a push button to turn on the circuit and the PIC to turn it off then I have tested a simplified circuit that uses a MOSFET. Low part count = lower cost! I didn't have a P-MOSFET laying around, but I *think* that you could replace my Q1 with one and that would eliminate R2 in my circuit too.
