The clock features a series of 3d-printed gears, all driven by a single stepper motor that [ekaggrat] found in surplus. The clock’s controller is based around an ATtiny2313 programmed with the ...

Analog clocks are beautiful things inside, using ornate gear trains to keep track of time in a dance of mechanical beauty. However, all too often, the complexity is hidden inside. This gear clock ...

The Plotclock is a small, 3D-printed clock that forgoes the traditional gears and springs for servos and an Arduino microcontroller. It writes the time. And then erases it.

The Manifold Clock Kickstarter project embraces the mathematical concept of Riemann surfaces to create an artsy 3D timepiece that expresses time through shape and movement.
