Clock project Part 1

Posted in Contest Entries with tags , , on November 30, 2011 by jackBuffington

This is the first of several posts about an entry that I am making for the laser cutter contest.  The end goal here is to have a clock that has no moving parts and no electronics that still manages to tell the time accurately.   This will be something of a modern-day sundial except that it will display the time indoors.   The way that it will do this is it will have a box that sits outside.   The box will have a hole in it that allows a beam of sunlight to pass through to a series of optical fibers mounted in the back of it.   These fibers will run to the back of the clock face and will back light a frosted piece of glass to indicate the time.   This first video shows how I cut the face of the clock out of a sheet of aluminum.
