There’s no shortage of projects that replace your regular board game dice with an electronic version of them, bringing digital features into the real world. [Jean] however goes the other way around and brings the real world into the digital one with his Bluetooth equipped electronic dice.
These dice are built around a Simblee module that houses the Bluetooth LE stack and antenna along with an ARM Cortex-M0 on a single chip. Adding an accelerometer for side detection and a bunch of LEDs to indicate the detected side, [Jean] put it all on a flex PCB wrapped around the battery, and into a 3D printed case that is just slightly bigger than your standard die.
While they’ll work as simple LED lighted replacement for your regular dice as-is, their biggest value is obviously the added Bluetooth functionality. In his project introduction video placed after the break, [Jean] shows a proof-of-concept game of Yahtzee displaying the thrown dice values on his mobile phone. Taking it further, he also demonstrates scenarios to map special purposes and custom behavior to selected dice and talks about his additional ideas for the future.
After seeing the inside of the die, it seems evident that getting a Bluetooth powered D20 will unfortunately remain a dream for another while — unless, of course, you take this giant one as inspiration for the dimensions.

A great many of you will remember the game of Snakes and Ladders from your youth. It’s a simple game, which one grows to realise involves absolutely no skill – it’s purely the luck of the dice. [Alex Laratro] noticed that without player decisions to effect the outcome, the game was thus a prime candidate for simulation.
[Alex] wanted to dive into the question of “Who is winning a game of Snakes and Ladders?” at any given point in the gameplay. A common approach would be to state “whoever is in front”, but the ladders might have something to say about that. [Alex] uses Markov analysis to investigate, coming to some interesting conclusions about how the game works, and how this compares to the design of more complex games like Mario Kart and Power Grid.
Overall, it’s a breakdown of a popular game that’s simple enough to really sink your teeth into, but has some incredibly interesting conclusions that are well worth considering for anyone designing their own board games. We love seeing math applied to novel and fun problems – and it can solve important problems, too.
The quality and attention to detail seen in [Ian Martin]’s build is impressive regardless of his choice to build a functioning holochess set. We’re not to take away from the nerd-gasm this build invokes, but we’d rather draw to attention the craftsmanship of the builder. Sadly [Ian] doesn’t have a proper blog or product page but you can view everything he posts about the project on his social networking page and get his take on the finished work in the video below.
This build is not just a well engineered mechanical design, the electronics that run the controls and indicators are [Ian]’s home brew Arduino Mega shields. A complete game requires two sets of electronics, one for each side of the table so rolling his own shield was probably a space saving decision.
Each of the figures used as game pieces were hand sculpted and painted (is that a Rancor to the right?). User controls are presented in true-to-form fashion with 54 buttons, 26 lights, 10 knobs, and an LCD screen with custom bezel to display custom monster status. Nope, the monsters aren’t animated holograms but to make up for that [Ian] built in ambient noises so you know which are still alive. This is our first time discovering that there is a name other than “Holochess” for the game: Dejarik. We’ll leave it up to the reader to figure out how it’s played.
This is an impressive build and we can’t wait to see what else [Ian] comes up with in the future. We have covered Star Wars builds before and some interesting board game builds but never where the two meet before this.
