Decision Maker

Funway Electronics Project 8

The circuit was developed many years ago and sold in a small box with a label on the front. This label gave alternatives besides two light emitting diodes: yes/no; in/out; heads/tails; etc.
Many thousands of these were used throughout the country to make important decisions. Even the Prime Minister of Australia had one on his desk for the most crucial decisions!
An alternative use for this project is to experiment with ESP – extra sensory perception. Have you got it?
