Eyes mechanism
The Eyes in the Bushes

This is one of our first effects. Four sets of eyes blink in irregular patterns in a bush near the front door. A motor drives a belt which slowly turns a metal can. Contact brushes made of wire and scrap spring metal ride on the can. Lines painted on the can break the contact to the eyes to make them blink. The eyes are pairs of red, yellow, and green LED's mounted in black-painted pieces of wood. A note for using food cans for electrical contacts: scrape the anti-rust coating off first!
