DIY D&D Gauntlet Rolls Some No-sided Dice

Players of role playing games like D & D roll a lot of dice. You may even get sick of rolling die after a while or are just looking for a new high-tech way to roll dice. If that’s the case, here is your next DIY project.


This DIY gauntlet “rolls” the die for you. Doesn’t matter if it’s a 6 sided die or a 20 sided die since no physical die are involved. It’s a wearable cuff that will roll 100, 20, 12, 10, 8, 6, and 4-sided die for you in response to your arm movement, thanks to an accelerometer, an Arduino controller, and a 7-segment, 4-digit yellow display.

This would come in handy for quite a few games that I can think of besides D & D. Just flip the switch, shake your arm, and it works it’s magic. If you want to make your own, follow the instructions found over at the Spark Fun Electronics Blog.
