Build your own laser tag system

This homebrew LaserTag game uses a cheap laser pointer combined with a toy gun and a PIC16F628A microcontroller that connects up to a piezo transducer which is used for producing various beeps. The 5 pin header plug at the bottom of the device is used to connect to a programmer for in-circuit programming. Check out all the details at the link below.
