He based the design of this device on complete randomness. He took a radioactive element that radiates a random charged particle, found in smoke detectors and used it as the input to his device because it too would be tied to the conscious field like all other things in our universe. The field if it was conscious and existed outside of our time he thought it might know how to deliberately make the element radiate a helium particle to then choose a random character on his computer. He had a friend of his design a random generating character program that when triggered displayed a random character from all the characters available on the computer. He set up a random pathway from the Geiger counter.
