DIY RFID Keyless Entry System

A few years ago I built a keyless entry system for my shop using a keypad, now it is time to update it to use an RFID key-fob. My homemade door actuator was made from parts out of an old VCR. The electronics controlling the system consist of a few components, a NE555IC (timer), a small NPN transistor, and a double poll double throw relay.

This video outlines the whole project including the RFID module, homemade door actuator, and door actuator timer and relay circuit.
