I've been working on the Magic Clock off and on for about 8 months. The finished clock includes an etched brass face, a one-of-a-kind custom movement, a wireless router and arduino based driver all fit into a salvaged clock body. Along the way I learned a ton about servos, arduino programming, gear ratios, etching brass, CNC programming, and lots more. The assembled clock can still be opened for maintenance. Here's what that looks like:
And Here's a short clip showing the hands in motion.
*I've had some good comments and questions about the hands and face. The arrow end is the indicator of the current location or status. Several folks have commented that shrinking the pictures and varying the length would make the face more readable and eliminate the "stacking" when more than one hand is pointed to the same status. I agree. This will probably be one of my next improvements.
