Jake Ketchum‘s Automatic Media Deactivation System attaches to a standard power strip and shuts off all power to a room’s electronics when its smart sensor detects that a person is no longer in the room. When someone re-enters, the system is switched back on. He demonstrated his invention at Maker Faire Bay Area 2011.

    This is cool. However, they make power strips that do this automatically. :) One outlet is the “master” and the others are based on it. When that 1 outlet goes to a low-power state, it cuts all power to the rest of the outlets. For instance: when you turn off your TV, it cuts power to game console, movie player, etc.

      Not quite that I’ve seen.  The commercial ones detect when you turn on a device from stand-by.

      This detects when you enter the room and restores power, similar to a motion-activated light switch (in fact, an strip on a switched outlet going to an OTS Motion activated light switch may be a similar solution functionally) This could be useful if you have devices that have longer boot times from cold: the device could get a head-start before you press the power button.

        No, it’s not *quite* the same – but it’s a LOT easier to implement. :)

    Clever, but the hard way of doing it.  Someone needs to teach that youngster that high voltage is not going to bite you unless you are careless.   

    Someone needs to teach him relays and working with 110Volts.
