An Internet Doorbell

Our photography department takes photos of new employees but the photographer's offices were not right next to the studio.  They needed a way to be easily notified if someone had arrived to have their portrait done.

I came up with an easy solution using an old keyboard and and old computer that was not being used for anything else.

I disassembled the keyboard and removed the circuit board.  All I had to do was solder a wire pair to the circuit board to represent one of the keys then run the wire to a doorbell button placed on the wall near the door.

I used some simple macro software to detect the push of the selected button on the keyboard and run a program to send a system message to the photographers who all got a pop up on their screens indicating that someone was at the studio door.

It was a simple solution costing only the price of a doorbell button.

I love doing this stuff.
