DIY LED based Analog clock

Hackedgadgets member Alan Parekh shared various versions of LED based Analog clock. You can build your own analog clock using the following materials:

  • One homemade clock uses a PIC16F877 Microcontroller with a 20MHz clock, it also has a DS1307 real time clock with battery backup.
  • 169 x 700mcd diffused white LED’s connected in a matrix configuration
  •  24 hand positions which gives a resolution of 2 to 3 minutes per hand

For version 2 of LED based Analog clock, the HEX, build pictures & Circuit diagrams can be downloaded from  http://www.filefactory.com/f/68dd353646ae4a22/
