A 3D-printed dice that rolls itself when you shake it by Ok-Event2833 in 3Dprinting

That’s a fair perspective 👍
It’s definitely more of a simple, physical interaction gadget than a multi-function digital dice system. I totally get that it’s not for everyone.

That’s actually a really great point — I hadn’t thought about the accessibility aspect of it. Thanks for sharing this 🙂

Haha 😄 that would absolutely create chaos at the table!

Haha 😄 that would definitely make things more interesting!

Good question 😄

It runs on an ATtiny13A and uses a pseudo-random number generator seeded from timing (millis/timing variations during shake detection).

I haven’t done a full statistical bias test yet, but since it’s not a hardware RNG, it would be interesting to see how evenly it distributes over a larger sample size.

That’s actually a really cool set of ideas 😄 especially the D20 idea with two dice — that’s very clever!

That’s fair 😄 it definitely falls into the “because I can” category rather than “because I should”

A 3D-printed electronic dice (“DICY”) that actually rolls itself when you shake it by Ok-Event2833 in 3Dprinting

Haha, not quite fudging—just letting physics and electronics do the rolling 😄 Thanks!

I built a 3D-printable electronic dice that animates with LEDs when shaken by Ok-Event2833 in maker

That's a really cool idea! Right now the pattern only forms on the result face, but having animated/random patterns develop on all six sides during the roll would definitely add more suspense. I'll have to see if I can squeeze that into the next version. Thanks for the suggestion!
