The wizards at Sparkfun, an open source hardware company, show us how to make one of these spiffy furry barbarian leather arm-bracers with a charmingly anachronistic D&D dice-roller built into, built around a Lilypad soft Arduino controller.
I’ve got nothing but respect for the DIY/open source community who take conductive thread, LEDs, and Arduino boxes and make them into marvelous little working crafts. I find it all a bit above my metaphorical pay grade. However, if there was anything that was going to convince me to learn how to rig a circuit, it would be the project that Dia forwarded to us yesterday. ,p> It’s a fur-lined leather gauntlet that can roll 100, 20, 12, 10, 8, 6, and 4-sided dice with the flip of a switch and the shake of a forearm. It combines my love of tabletop with my desire to live in the future where we all poke our wrists to get things done.
Theoretically, there's a complete tutorial for this beauty, but it's 404 at the moment. The link below goes to The Mary Sue's writeup.
