This is a fantastic introductory electronics kit that comes with your choice of large red or green LEDs and everything else needed (aside from a soldering iron, solder, and flush cutters) to make one electronic 6-sided die. (The manufacturer says: “The name Dice Kit sounds a great deal better than ‘Die Kit’, so we bent English grammar rules just a little in the name of making a marketable product.” Good move!)

The finished project is fun to use: you lift it a half-inch above the table and drop it to “roll” the die. A piezoelectric buzzer senses the impact and triggers the circuit to generate a random number and illuminate the LEDs. Everyone I show it to smiles at the way it works.
