I can think of so many ways to do this, from boring to insane :) * Mount a switch on top of the door that gets unpressed when the door opens, and connect to the serial port. Then read the pin status. * The same, but mount the switch behind the door so that it gets pressed when the door opens. * Use a magnetic switch instead, and read it through the serial port. * Put a keyboard behind the door, so that the door presses against a key when it opens. Map the key to a script. * Attach a mouse to the door and react on the mouse movement. * Attach a GPS sensor to the door and measure movements. * Attach a USB barometer and detect the air pressure diff when the door opens. * Attach a USB gyroscope to the door. Detect movement. * Attach a USB light sensor (Arduino?) and detect movement. * Put an RFID tag on the door, and attach an RFID reader, to detect when the tag approaches the reader. * Attach the laptop to the door and use the built-in gyroscope (if available). * Same, but use the gyroscope from the HD. Might require firmware hacking. * Don't oil the door and evaluate the microphone input. * Attach any USB device, but route the 5V line through a switch attached to the door. Detect when the device attaches. * Mount the laptop behind the door so that the door opens/closes the laptop lid. Detect wake/sleep state. * Fix your credit card to the door and have it move through a card reader when the door opens. Check account balance through script. Send pix! regards, Robert
