This Instructable offers a walk-though of the "Electronic Dice Kit" assembly.
This kit is available at etsy
This kit comes with everything needed to complete the project (shown below) including a battery.
This is a nice kit for beginners to learn to work with solder, or anyone looking to spice up a game of Monopoly...or Chess.
There is a single momentary button, when it is held, a random number will light as it would be displayed on a die.
