The uM-FPU64 chip is featured in an excellent article by Geoffrey Gill in the November, 2012 edition of Nuts and Volts magazine. The article is entitled, Steampunk Planetarium Clock.
The clock calculates the current location in the sky of the Sun, Moon, Planets and 500 brightest stars, then displays the sky view for a specified location on a 4D Systems uLCD-32PT graphical display. The display interfaces with the uM-FPU64 chip, which performs all of the astronomical calculations and provides the real-time clock.
