Credit where credit is due, this project was inspired by Jon Chandler's Clock for Geeks.
After reading through one of Jon Chandlers recent projects, I was rather inspired to make my own! The Geek Clock is a great spin on a more then well known concept - displaying time. His method employs a Servo, PIC and a little intuition.
Design
Rather then using the paper clock face like Jon did, I experimented with a few other methods to spice up the presentation. At work, we recently acquired a large Vinyl Printer and Gerber Cutting machine. Long story short, we can make all sorts of decal stickers (very handy indeed!!). It was a pain staking ordeal creating the clock face on the Omega software (for the vinyl printer/cutter) as it was written in the early 90's and very vector based graphics. In the end I got something that looked like a clock.
Originally I was going to use the decal cut-outs to create the clock face - problem was the decal stickers would not adhere well to wood. I could have used glue, though any excess would have lead to a bad varnish job. Then it struck me - what if I use the external part of the sticker as a template - to paint through?
The Schematic
Here's the schematic for the project. At the heart of the circuit is a PIC which interfaces with a DS1307 Real Time Clock (RTC). The CAL header provides a function to calibrate the servo motor with the clock scale.

Good work what a clock design may be i'll try it
