Mechanical clocks have always fascinated me. The way all of the internal gears, springs, and escapements work together to result in a constant reliable timepiece has always seemed out of reach for my limited skill set. Thankfully modern electronics like Arduino and 3D printed parts can bridge the gap to create something simple that doesn’t rely on small precise metallic parts.
This minimalist wall clock hides a pair of 3D printed ring gears driven by inexpensive stepper motors that rotate magnets behind a classic walnut veneer.
