Electronic Die powered by 3 V lithium battery
This article describes an electronic version of an age-old tool for games of chance: the die. It is, however, not cubical, but the number of spots on the six faces of the traditional cube are represented by LEDs on a small printed-circuit board that light when a contact is touched by hand. Powered by a small 3 V lithium manganese button cell, the compact device may also be used as a trinket for which a clip can be soldered on to the board.
