## Automatic Dice Thrower

The Dice-O-Matic is 7 feet tall, 18 inches wide and 18 inches deep. It has an aluminum frame covered with Plexiglas panels. A 6×4 inch square Plexiglas tube runs vertically up the middle almost the entire height. Inside this tube a bucket elevator carries dice from a hopper at the bottom, past a camera, and tosses them onto a ramp at the top. The ramp spirals down between the tube and the outer walls. The camera and synchronizing disk are near the top, the computer, relay board, elevator motor and power supplies are at the bottom.”

As someone who has designed random number generators professionally, I find this to be an overly complex hardware solution to a relatively straightforward software problem. But the sheer beauty of the machine cannot be denied.

What I am curious about is what kind of statistical anomalies there are in the dice themselves. At 1,330,000 rolls a day, we can certainly learn something about the randomness of commercial dice.
