Inline Clock Uses Incandescent Display |
 Here
is a different type of digital clock that uses a single digit to read
out the time serially; i.e., if it the new time is 3:51, the clock first
displays a 3, then a second or so later displays a 5, then finally a
1. Obviously it cannot update the time every second, but that is not
what this kind of timepiece is meant for. It is purely a conversation
piece. What makes this clock, designed and built by David Christianson,
is its electromechanical incandescent display. "The displays make use
of a small piece of film and 12 lens systems to project whatever of
12 images you want to provide." Reportedly, this method was devised
in the 1960s and was very expensive even back then - about $100 per
digit. No info is provided about the exact display used, but it seems
any 7-segment display type can be adapted, even a cheap LED.
