New Life Goal: Make a Leather Bracer that Rolls Dice

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.

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.

According do Dia, the electronic components required are simply:

  • Conductive Thread
  • LilyPad Arduino 328 Main Board
  • LilyPad Accelerometer ADXL335
  • LilyPad Slide Switch
  • 7-Segment Serial Display
  • Lipo Charger basic
  • Polymer lithium Ion Battery

And then you, uh…

Do some things…


Look, I just want this. Her detailed instructions are here.

(Thanks, Dia!)

    I would SO wear this die roll cuff to D&D night and Magic tournaments! If it could also keep track of life for Magic players… or maybe that could be a separate cuff for my OTHER arm! YES!

    I thought the whole point of still using dice was that the player was in control of it. There really is no charm to pressing a button and a computer telling you a number, so I would not opt to wear this, personally. Half of game jokes are about how bad or good a player is at rolling dice.

  • Heretica Neue

    Hmm, you have a point. Maybe I’m thinking too much in terms of Magic instead of D&D.

    I’d put a shake sensor in it, so you push a button, then smash the table to get a number.

    Cool as this is, there is no true replacement for real dice.

    Hi bigattichouse! Is it wrong to comment on my own project? I hope that’s not wrong! I just couldn’t bear not to! This actually IS a shake sensor- it responds to forward motion, so punching your fist or, alternatively smashing it down into the table, triggers the roll. I completely agree that pressing a button would be kind of boring! :)
    And while I’m intruding anyways, don’t worry guys. I totally didn’t throw out my normal dice. Digital is fun, but analog is forever. <3

    When I first read the post, before I saw the picture, I was thinking someone had made the dice cuffs from Quag Keep….  Still waiting for that one…
