      Word Clock


      Picture

      Electronics: PIC 16F690 microcontroller and DS3231 RTC with battery backup, driving a multiplexed display of approximately 34 flat-top white LEDs with wide angle dispersion. (1-2 LEDs per word.)

      Face is adhesive sign vinyl affixed to the back of 1/8" clear acrylic. The baffles are whatever thin strips I had on hand, and the whole thing is encased in a  low-profile 12x12" frame.



      Inspired by this great clock.
