Step 2Setup I
(1) Install yahoo messenger on your work and home computer: http://messenger.yahoo.com/
(2) Connect a webcam to your work computer. Set it up so it's looking at a dark, flat surface. I used an existing PVC frame I made for the camera. (first image)
(3) solder or wire wrap a long length of 30 gauge wire wrap wire to each of the photoresistor leads.
(4) Tape photoresistors to your home computer's screen. I did this by first taping the photoresistors to a clear piece of plastic with black electrical tape, then taping the plastic to the screen with scotch tape. (second image)
(5) I would recommend putting the 'home computer' in a box to exclude any non-screen light. otherwise light from windows could interfere during the day. You will be maximizing the yahoo messenger video feed on this home computer so that it fills the whole screen (or as much of the screen as needed to be able to activate all of your taped on sensors).
