dicereader cc Dice reader version 1
From the MAKE Flickr pool

Steve Hoefer shares this photo showing the first iteration of his dice reader project -

Working on a robot that plays dice. Since the “robot” part is easy i started with the dice reader which can read the number of pips on the dice that’s placed face down on it.

Version 1 just uses 4 photo resistors with white LEDs behind them. It only works right about 70% of the time and is incredibly sensitive to ambient light, but it’s pretty good for about $0.99 worth of parts and a first try. V2 will add more, smaller, sensors with greater sensitivity.

Judging from the ongoing conversation on his blog, it sounds like the next version will incorporate IR sensors. Have a closer look at his setup on Flickr.

… and for a larger scale, software-intensive approach to the problem, check out GamesByEmail’s Dice-O-Matic.
