I just finished programming my gearclock that I showed off last week. I added a Chronodot real time clock so it keeps perfect time! I also wrote up an instructable here: http://www.instructables.com/id/Laser-cut-gear-clock-with-Chronodot/ so you can build your own. I also have some stepper motors if you want to buy them from me (cheap!). Put your Arduino to work! Learn how to use the lasercutter! Brian
