I want to make a light up clock of the constellations throughout the year so I'm wondering if there are clock movements sold that take a whole year to make one revolution?
And got the following answer:
There used to be timers for outdoor lighting control that had a one year cycle that changed the on/off according to lighting needs in the different seasons. These mechanical ones were undependable. Now only electronic 365 day timers are made. Here is an article about what you want: http://www.getty.edu/art/gettyguide/artObjectDetails?artobj=6266 Edmund Scientific thirty to fifty years ago sold the Spilhaus clock that showed the constellations, the earth day/night globe, and the time. It was $200 then. Now it is a collector's item for ebay auctions. Here is a $50 watch that does the stars for every day. Manual control, though. http://www.thinkgeek.com/gadgets/watches/706f/ Here is one available now, also with manual (you move it every day) control on the star field dial. $35 http://www.telescope.com/control/product/~category_id=space_and_astro/~pcategory=giftcenter/~product_id=58471 You can make a clock that has a one rev per day (1 RPD) AC timer motor that drives a planisphere (Philips makes a nice one of various sizes and latitudes on Earth). http://www.amazon.com/Philips-Planisphere-Latitude-42-USA/dp/B0017PIOP0 http://www.washjeff.edu/physics/plan.html you can make your own from this. http://www.vcas.org/star-wheels.html That would create the 24 hour motion of the stars for any single date. But you must advance the chart a small amount every day, because a sidereal (star) day is 3m56s shorter than a solar (earth clock) day. You can use a 24 hour electronic timer to create a 3m56s power on period for a second 1 RPD timer motor that is carrying and rotating the first 1 RPD timer motor and planisphere. That would advance the planisphere chart the right amount every day (1440m/day divided by 365 is 3m56s). Sorry, but that is about as uncomplicated as I can make it without going into electronic design of a sideral rate drive motor and control system, or using special gears that are expensive to buy and mount. Astronomers like me use telescopes with drive motors that have a slightly faster rate of drive (23h56m04s revolution per day) for following the stars. It is not easy to duplicate mechanically, but quite easily done with computer control of DC or stepper motors. Easier is to go to www.heavens-above.com and view a full sky chart for any hour, any day, seen from your location. Edit: I thought of another way to make the planisphere drive at sidereal rate. Suppose you drive it at the rim of the planisphere with a rubber wheel on a 1 RPH (one rev per hour) timer motor. The planisphere edge diameter is 12 inches, for example. The driver wheel is a half inch. That gives the 24 hour daily drive. If you wrap a piece of plastic tape around the driver wheel, making it a tiny bit larger, about .50136 inches, the planisphere will go faster. You can adjust the diameter of the driver or the planisphere on a daily basis until it is about perfect. Good luck!
