        The flo-control project. Science application at its best.

                 \_ Oh I see. How rich do you have to be to live there?

She also has a habit of catching various animals, dragging them inside through the cat door, and letting them loose so they can be chased for hours. To put an end to this we have built a computer-controlled device that visually determines if Flo is carrying anything in her mouth when she enters, and if she does, it simply does not let her in. This commercially available cat door (Cat Mate) already has an electromagnetic latch, normally activated by a small magnet that the cat wears around its neck. We rewired the circuit so that the latch is controlled instead by the little gray box to the left of the computer, which is connected to the serial port. But the really interesting stuff is on the other side of the door.
