Dice rolling machine can make over a million throws a day

I introduce to you, the Dice-O-Matic:

It was built because the guy who runs GamesByEmail.com had complaints from players that his “random” dice rolling computer program wasn’t truly random:

So, he says, he got the idea to build a real dice-rolling machine. And then went overboard. I like him:

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.

The dice start the cycle at the top of the ramp, toward the rear of the machine. The ramp is comprised of ten steps, each at about a 20 degree incline, with a right hand thread through two and a half spirals. Two layers of cloth covered foam (car headliner) keep the noise down. Felt covered foam quarter-obelisks are at each corner, sewn to the side padding. It took a few tries to get the pitch just right. Too shallow and the dice stopped tumbling, too steep and they would start banging against the Plexiglas. Now they roll very well, sometimes stopping and then getting knocked back into the stream. Perfect.

The hopper at the bottom of the ramp is pure seething violence.
