Weirdly Wonderful Upcycled Mechanical Clock Relying on Ball Bearings to Tick

Pendulum rolling ball clock by Turnvater Janosch.  Material: – Wood (mainly remains) – Plastic gear wheels – Brass wire (1.3mm, 3mm) – Steel wire (bicycle strokes) – Old flat iron.

Turnvater Janosch’s website welcomes you to his wonderful world of  “handcrafting and weird machinery”, and if this pendulum clock is anything to go by, the description’s pretty apt.

The clock runs for 12 hours, driven by a weight of 2.5 kg sinking approx. 1 meter during that time..Every minute a marble is lifted up and goes down a marble run with three flipping traps that count marbles for minutes, five-minute-steps and hours. The timekeeping element is a second-pendulum with a pinwheel escapement. The clock achieves a drift of less than 1 second per day.
