The Bulbdial Clock: High-tech Sundial

Bulbdial Clock - a high-tech sundialThe Bulbdial Clock is an electronic take on the sundial. Instead of relying on shadows cast by the sun, this timepiece features three layers of colored LEDs that rotate around the clock face, casting shadows to represent the hour, minutes and seconds. The Bulbdial clock is lit up by three layers or rings of LEDs that cause the gnomon (the object in the center of the clock that casts the shadow) to have three shadows.

While a traditional sundial displays only the hour, the Bulbdial Clock has three rows of red green and blue LEDs which shine a light onto the gnomon (or central object), creating the three “hands”. When the lights overlap, a host of secondary colors are produced. So aside from the hour hand, there’s a minute and a second hand as well.Bulbdial Clock - a high-tech sundial2

The picturesque clock is available in four case designs, laser-cut acrylic, including Tortoiseshell, Abalone Pearl, Black Granite, or Granite back/Clear front.

The Budbdial Clock also has optional USB connectivity for either syncing the time with, or charging from, a PC. The Bulbdial is Arduino-based, and both it’s hardware and software are open-source, which means that the clock is hacker-friendly. For those with basic soldering skills, the Bulbdial Clock is available now as an assembly kit from US$65 at http://evilmadscience.com/tinykitlist/156.
