| Weston Bye:
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. 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 can be contacted by e-mail at wcbye@sbcglobal.net |

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. :thumbup: |
