Do you need a to find a more sanitary way to roll the dice at your next socially-distanced board game gathering? [CJA3D]’s pop-o-matic mason jar dice roller can roll the bones two different ways — either by hitting that big, inviting arcade button, or though a web app that everyone can access on their own phones.

We think this looks great, and is a great reuse of a glass jar. The brains of this operation is an ESP8266, which drives a continuous-rotation servo underneath the dice. Push the button or use the web app and the servo disturbs the plate, moving the dice around.

Besides the sanitary aspect, one benefit of using the web app is that there are four different speed presets for the servo. As a bonus, [CJA3D] included the files for a pair of printed 6-sided dice. Click through to the project to see it in action.

We know you take games seriously, and so do we. Just look at this dice roller that uses machine vision to ensure fairness.
