A microcontroller is powered from a 5V brick (always connected). It controls a set of relays, which in turn enable power to individual power sockets. Upon boot the microcontroller waits a few seconds before enabling each of the power sockets. Then it sits idly by until the next power outage. All of this is enclosed in an electrical distribution box. A microcontroller is powered from a 5V brick (always connected). It controls a set of relays, which in turn enable power to individual power sockets. Upon boot the microcontroller waits a few seconds before enabling each of the power sockets. Then it sits idly by until the next power outage. All of this is enclosed in an electrical distribution box.
Optionally a speaker is used to indicate the state of the power socket "boot" process. A circuit breaker may be added to guard the whole device from tripping the main circuit breaker in the building.
