      Emily's True Binary Clock

      #000099
      Anyone can read the plethora of ordinary binary clocks out there. Technically, they're actually binary coded decimal (BCD) clocks, in which each digit --  tens-hours, hours, tens-minutes, minutes, etc. -- is represented by a line of LEDs blinking out 0-9 in binary.


      In this version, the hours , minutes  and seconds are given their full binary representation. Reading  from top to bottom, the time is 9:12:55.


       Emily's first (and probably last) use of a drill press.

      Schematic and code available on request.
