Here is my latest project, running in the pages of Digital Machinist magazine.
First, a closeup of the "clockworks". A 60:1 worm gear drives a horizontal shaft that carries the Geneva pinion that drives the 12:1 Geneva wheel for the hours, and a 1:1 spur gear to drive the minute hand.(http://img.photobucket.com/albums/0803/Weston/GenevaHours02_zpsa117a2b7.jpg) (http://smg.photobucket.com/user/Weston/media/GenevaHours02_zpsa117a2b7.jpg.html)
I call it Geneva Hours because I used a Geneva mechanism to advance the hour hand.
Although I used CNC for many of the details, I designed the clock so that it could be built using manual machines.
The clock uses the same circuit board, with a few parts added, that I designed for the Magnetic Gear Clock.
The series will run 3-4 issues for the important details and possibly another dealing with surface treatments.
As a service to readers of Digital Machinist, I am again offering circuit boards, kits and assemblies.
Bare circuit board $15.00
Electronic parts + board $40.00
Assembled & tested $55.00
I also offer coil winding service, where readers mail me their machined bobbins and I wind the coils and add lead wires, and then mail them back. The cost is $40.00 for the four coils.
All prices are postpaid in the U.S.

I like it :) I like the idea that a 'clock' can be just a display (and perhaps a counter) for a electronic time keeper , thus avoiding the problem of accuracy without loosing the essential mechanical nature of a clock.
