555 oscillator - Circuitos electrónicos
This little circuit will enable a remote controlled switching of an appliance situated in the next room using the concept of power line communication, which involves the use of home mains wire for transferring data in the form of high frequency pulses through the mains wire, superimposed over the existing mains frequency. The idea was published in the datasheet of the IC LM567 as one of the application circuits, among the many other outstanding ones. The IC LM 567 is actually a specialized tone .......

This circuit works much like the classic 555 timer, but draws only about 1.5 microamps from a 3 volt battery. It is highly stable under varying temperature and supply voltages.
