Projects for electronic dice have previously appeared in Elektor Electronics. Different designs and shapes have found their way into the magazine, but one thing they had in common: they were all two-dimensional dice. But now that is about to change! Electronic dice are usually constructed on flat boards. To give the impression of a ‘real’ dice, seven LEDs are often used in a pattern similar to that on a dice. The original intention was to base this circuit on a traditional ‘flat’ design, until somebody from the editorial staff suggested that you should really be able to throw a dice. After all, a dice is not an item that lies still on the table.‘But that is the advantage of an electronic dice!’ you’ll say. You don’t need extra space to throw it and it won’t roll off the table either. And this was exactly how our design staff reacted to this unusual suggestion. But the editor was adamant: this dice has to roll!
