3D-Printed Sundial Tells Time Digitally
This time-keeping dial meshes the contemporary and historical in digital form
Sundials have been used to measure local time since ancient Egyptian astronomers developed the instruments in 1500 BC. They've been a part of all major cultures and are considered one of the most accurate and sophisticated ways to tell time. Going by the moniker Julldozer, a French inventor has developed a sundial that's not only printed using 3D printing technology, but also projects the time in digital form.
The sundial functions like all others. It uses the sun to cast shadows in order to tell the time. There's no electricity or battery used in the process. What differs is the actual design.
