About this project
HEX is a new kind of dice that merges the best of magic and minimal design to create an all new gaming experience!
The Ultimate in Minimalist Design
Each HEX die is machined from two standard 16mm dice blanks. The finished die is placed in an acetone environment to smooth out any ridges or imperfections (note: the prototype is not final and has a visible seam, the real deal will look great, I promise!)
- 21 LED's
- 16mm Standard Dice Size
- Ultra-low-power Accelerometer (MMA8491Q)
- Ultra-low-power Microcontroller (MSP430G2101)
- 2 LR44 Batteries
Leave it to Chance!
Get skill and psychology out of the way -- there's no way to tell which side is which in HEX mode until the roll is over!
Two LED Modes
HEX mode - the die remains blank until the roll has been made, then the result fades into view. Right now I have the opposing side light up too, should that be in the production version?
Full Color mode - all LEDs activate when the die is shaken and remain on for about 10s after the roll
LED Color Options
Based on feedback I am introducing color options! You'll now be able to opt for single color LEDs (all green, all orange, or all red) if you're not too keen on the standard multicolor configuration. You'll be able to choose the desired quantity of each type if you order multiple dice!
Long lasting performance
The microcontroller, accelerometer, and battery chemistry were selected for ultra low standby current consumption and will easily last a year of casual gaming and a shelf life of several years. However, avid users may need to replace the batteries every few months due to high LED light use. (Note: the dice may be opened with heat to soften the glue)
Although the current prototype is good, there are some adjustments that I would still like to make before production.
- Keeping the lights in well-defined circles so they don't bleed across the surface of the dice. I plan to accomplish this by using reverse mount LEDs that would shine through holes in the circuit board
- Optimizing the program logic to ensure glitch-free operation
- Potentially having the shell of the dice injection molded instead of milled from off-the-shelf dice blanks (this might also allow for a snap fit enclosure for easier battery servicing)
Of course, I look forward to incorporating feedback from you all as well!
Risks and challenges
Several prototypes have been made, and I feel confident in my ability to make HEX at a larger scale. However, depending on the number of backers, adjustments may need to be the production process. This would likely involve third parties to assist in fabrication and the associated time and uncertainty involved with that.Learn about accountability on Kickstarter
