This clever clock uses bicycles as an inspiration and the end result is really cool.

 

"Cutting the frame with my Shapeoko from 1 x 6 OAK"
"Creating a pocket for the motor"
"The frame was made with 4 slices that were glued together."
"Lots of sanding."
"Bronze bearings mounted in a cover plate. One bearing for the cassette drive shaft and the other for the motor output. I needed to add a gear to reverse the direction of the motor output."

"I epoxied a piece of UHMW in the center of the cassette and threaded the end of a 1/4" rod."

"Using a bearing to center the shaft"

"This is the synchronous motor with the shaft coupler and the gear. The motor output shaft was only about 1/8" long and 1/8" in diameter so I couldn't attach much.. thus the expensive coupler."

"After several failed alternatives, I drew up chain links and had them 3d printed. Luckily there is a MakerBot store nearby."
"First design.. I forgot to provide clearance for the cog teeth, nothing a little dremel work couldn't fix"

"Completed Clock"

"This is sped up. The actual clock rotates at 1 rotation per hour"

All the 12 hours rotate every hour?
Too bad it's a useless clock, looks cool.
