Servo Driven Magnetic Analog Clock

Servo Driven Magnetic Analog Clock

grabcad

This is the inner mechanism of an analog clock that can control 3 magnetic balls to show seconds, minutes, and hours. The entire mechanism was driven by a single SG90 micro servo and a ratchet-pawl mechanism, which then powers a compound gear train to drive the 3 magnets in continuous, rotational motion. The servo can be easily programmed with an Arduino or a Raspberry Pi.The entire inner mechanism is 3D-printed with a Prusa MINI. STL files are also available.
