Nearly all sundials tell the time by using a gnomon’s shadow as the hour hand. But this very cool sundial by Thingiverse member Mojoptix displays the time like a digital timepiece.
Mojoptix used OpenSCAD to design a gnomon with many tiny holes.
The latest cool concept watch to show up on the TokyoFlash design blog is this unique timepiece which would tell time like a traditional sundial. However, this particular sundial doesn’t rely on the sun’s powerful rays at all.
The evil & mad scientists at Evil Mad Scientist Laboratories built upon the idea of a certain David Friedman for a digital sundial. A normal sundial relies on the sun and only displays the hour. 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.
