This digital clock uses 24 Arduino-controlled analog faces

After being inspired by a beautiful, if rather expensive timepiece, Ira Hart decided to make a 3D-printed clock with 24 analog faces that combine to form a single digital display. The overall device is controlled by a single Arduino Nano, which keeps track of the time using a RTC module. This unit coordinates 24 other Nanos on custom carrier boards, which in turn drive their own little clock face via a pair of steppers and a gear system.

When working together, these 24 clocks can tell the time in very large characters, and even show a variety of kinetic art as it changes from one minute to the next. It looks awesome in the video below, and build info is available in Hart’s project write-up.
