The Bulbdial Clock kit is based on an original design concept fromIronicSans.com and developed at Evil Mad Scientist Laboratories. It works like an indoor sundial, but with three shadows of different length. You tell the time just like you do on a normal clock, by reading the positions of the hour, minute, and second hands.The bulbdial we are carrying comes with red, green and blue LEDs for the ‘hands’, a black/smoke laser-cut enclosure and a wall adapter. When finished, it looks like the picture shown above!The Bulbdial Clock is sold as a soldering kit [?]. Basic electronic soldering skill is required, and you provide basic soldering tools: a soldering iron + solder and small wire clippers. You will also need internet access to read or download our detailed assembly guide. No additional knowledge of electronics is presumed or required. Easy «through-hole» construction and clear, photo-heavy instructions are provided. Assembly time: 1-3 hours, depending on your level of experience with soldering.
