Dear members, I am about to build a clock but could not find what I needed so registered here to try to find help from professionals. I searched all over the internet but could not find a battery operated quartz mechanism that would give me ONE revolution per year. Can anyone give me a link where to find these, for example ebay? I hope someone knows about these mechanisms. Thank you very much for reading this
i think of quartz movements as mass-produced in china, for as cheap as possible. yes, there are pricier more-featured ones, but i have to believe that everyone is going to make the same beast... ticks every second... because that's what people want/need. why would you want one revolution per year?
Thank you for your answer and yes, I noticed all these mechanisms are similar and for sure produced in mass at some factories in China. I would like to build a year 'event' clock.
got it... but more information would be helpful. - what is a one year 'event' clock? - if you could buy the movement you're looking for, all you would be doing is putting hands on it... as it's already built... yes? still confused.
I don't think you will find a 1 rev per year off the shelf quartz movement mechanism. But, that said a gear train could be built and powered by a quartz movement that would make 1 rev per year. It has been done with spring or weight drive movements some fair number of times over the last 200-300 years.
An event could be an anniversary coming up during the year or national holiday or sport event. I design and build the clock but not the mechanism.
Yes true, I calculated the gears I would have to cut and might try this if a quartz mechanism is not being produced. Thanks for your reply
yes... but... your way means that you'd have to have a separate clock for every event. if you used a regular movement (for example) you could 1) find one, and 2) create a method for setting multiple event alarms, all triggering a year apart.
It's called a cell phone ... no need to reinvent something that already exists in a highly refined state. It will even remind you before "the event", short reminders, long reminders, multiple reminders, E-mail you, message or call you at another number, etc. Willie X
willie is correct, except for the part about creating mechanical gearing... although the details of blob's vision are still a little unclear as of yet. i was envisioning something like a james remind-o-timer (inherited my dad's)... see this thread: James "Remind O Timer" you can set multiple alarms during a 12 hour period... could be extrapolated mechanically to do the same over a year, yes?
Are you going to account for Leap Years with the 100/400 year exceptions? That would be an interesting challenge to accomplish through gearing.
One can only hope that the battery will last that long. Mechanically, the quartz movement should have no issues... Uhralt
It would require some pretty good gear cutting to ensure that the slack in multiple gears didn't take 3 weeks to tighten up before getting the final output shaft under way. If you wanted to change and go with mains power the people at Geochron could help you out with a suitably geared down motor as the one in my Geochron takes a year to go through a season cycle.
