Equatorial Sundial – Solar Clock & Compass

Equatorial Sundial – Solar Clock & Compass This equatorial sundial is a precise and adjustable solar clock, designed to be easily 3D printed and used at different latitudes. How Does It Work? The sundial uses a gnomon inclined parallel to the Earth's axis, which casts a shadow on the equatorial plane. To align it to the equatorial plane, simply tilt it to the latitude where you are positioned. To align the gnomon to the Earth axis point it north. Since it aligns with the Earth's axis, the hour lines are equidistant, allowing an accurate reading of true solar time. The Sundial Plane have two faces. The esternal face (Face A) is used in spring and summer and the internal face (Face B) is used in winter and fall. Solar Compass Function – Find True North In addition to measuring solar time, this sundial can be used as a solar compass to determine True North. How to use it? Place the sundial on a flat surface. <s
