This is a larger version of an equatorial sundial built entirely from LEGO bricks. The segments are constructed using 1 x 2 hinge plates. These are bent at 15-degree angles to create half an arch with 12 segments marking the hours. It is mounted on a pedestal at the balancing point of the dial [...]
Vertical dials have faces on a vertical surface rather than a horizontal one. They are often constructed on the sides of buildings, usually on the south side. However it is possible to construct them on surfaces facing other directions. A vertical dial on a wall facing directly east can be used during the morning hours, [...]
Polar sundials, like equatorial dials, have the gnomon and face tilted to accomodate for the lattitude where they are to be used. These kinds of dials are especially adaptable to construction from Lego bricks because they use parallel lines to mark that hours rather than the angled lines used on a more traditional horizontal [...]
This equatorial sundial takes advantage of a happy accident of LEGO geometry.
As it happens, the inside bow of a 1×5×4 half-arch brick can be divided almost exactly into 6 sections of one stud unit each. That makes a full circle of 24 equal sections – ideal for sundial construction!
This dial is angled at 41 degrees [...]
This little equatorial sundial folds into a small unit just 1 inch by 2 inches by 3/4 inch high. It can be unfolded and assembled to be used anywhere in the world to accurately tell the time within a few minutes. It is constructed entirely from Lego pieces.
Step by step instructions are up at the [...]
