Don’t think I ever shared the finished product on this one, and figured it was worth it for the gearheads. I was the designer on a bunch of the parts of this; lots of work on material and finish, getting the 4-foot diameter brass disc made (had to source it from a shipbuilder, shipped from Maryland to Wisconsin to Texas), milled, and inked, and the overall look and feel.
My good friends at the engineering firm did all the heavy lifting. It was a crazy project, a one-off for a nerd, and I love it so much.
Copypaste from the client’s site:
The Earth’s precession moves the Earth’s vernal equinox a fraction of a degree every year. This movement defines our astronomical age. The clock tracks the ages by creating a line from the earth on the vernal equinox, through the sun and down to the year hand pointing to the year, the astronomical and astrological age. The song The Age of Aquarius heralds the coming of the age of Aquarius, predicted to be an age of enlightenment and peace. The Tycho astronomical clock accurately shows the Sun entering the constellation Aquarius in the year 2597. The clock tracks all 13 astronomical ages and 12 astrological ages over 27,000 years.
The Tycho Astronomical Clock is a dynamic centerpiece and while it tracks current time, it can be moved to any point in time from 11,000 BC to 16,000 AD and the planets will be accurately located to the best predictive locations defined by NASA and begin to track the time at that point on. The Tycho Astronomical clock can also be accelerated to elegantly demonstrate the movements of the planets showing the elegant movement of the planets through time. The clock can also demonstrate astronomical events including alignments and the earths precession creating a dynamic feature in any space.
Anyway, I think it’s pretty cool.
