A year ago I started building first prototypes of a device that would be capable of calculating #moon phases based on the historical Metonic cycle. The result was „Meton“, a 3D-printed lunar phase calculator. So if you need an #opendata moon machine, go ahead.

Or build it yourself, from oak and steel.
