Automatically Turn Off Your Electronics When Leaving The Room With Bluetooth

DIYer Mike has found a better way to cut down on your energy bill. He set up his electrical socket to turn off when he leaves the room. He originally set it up with a Linux desktop to control the electricity in the room with a bit of electronics tweaking and some code but realized he could do it better by hooking it up to a Bluetooth receiver.
Whenever he exits the room with his Bluetooth enabled phone in his pocket, the computer will detect that it is out of range and turn off the socket connected to his lights, monitors and other electronics.
