Manual 7 Segment Display
  When I think of a 7 Segment Display I think of a small display plugged into my breadboard with some wires plugged into it. This clock uses 7 segment displays that are nothing like that!. In fact these 7 segment displays are all mechanical and are actuated using tiny servo motors. Just think of the noise it would make if the time wasn’t set and it was flashing 12:00.
