DIY'er makes a pet access control system

If you're looking for a way to get your pups eating what you want, when you want, you might want to check into one DIY'ers clever solution for an RFID feeding scheme. The trouble all began when a gentleman named Mike Larsen needed to feed one of his dogs a special diet even though food had to be out constantly for his canines -- thus making that goal quite difficult to achieve. After discovering no commercial products to suit his needs (likely due to an apparent patent-hoarder), he decided to put his own solution together, using some RFID key fobs, a small proximity card access kit, a Radio Shack AC adapter, some loud buzzers... and a little bit of elbow grease. The system works by essentially "scaring" the special-diet-dog away from the food by the use of a loud buzzing sound, which isn't subtle, but certainly effective. Check the video after the break to see the system in action.
