Controlling access to a building? This sounds similar to things Steve Passe <smp@csn.net> and I were talking about. For home use, there's an electronic door strike plate you can get. Run 16VDC through it and it unlocks, allowing you to push the door open. Hook this up to a small transformer and small relay. Now, hook up a card reader, a numeric weatherproof keypad, or a microphone (and write some sophisticated voice recognition software) outside, and have it send results to the computer. Have the computer close the relay for about 10 seconds after identifying the person who wants to get in. Piece o' cake! -- Sean Kelly NOAA Forecast Systems Laboratory kelly@fsl.noaa.gov Boulder Colorado USA http://www-sdd.fsl.noaa.gov/~kelly/
