Any ideas Is this circuit going to be stand alone Any other circuitry around it, perhaps a microcontroller What circuitry does the timing device contain, or does it even contain electronics abdullah kahraman Mar 22 `13 at 18:10 Since you do not want much components, you can maybe remove pull-down resistor R2 if you can get away with small problems, such as a weak and short beep on power-on, when the
