Available only from Hammacher Schlemmer, this is the projection clock that connects to an atomic clock to project the most accurate time and forecasts possible. The device’s built-in radio receives time signal broadcasts for any location within the contiguous United States via a radio signal from the Atomic Clock in Boulder, Colorado. Two remote thermometers relay indoor and outdoor temperature back to the base station, which projects the current time and temperature up to 6' onto a ceiling or wall. It also shows time, alarm, temperature at the two sensors’ locations. Powered by the included AC adapter or six AA batteries (not included). 4 1/2" H x 6 1/3" W x 1 1/4" D. (11 oz.)
