Guy Designs Digital Sundial That You Can 3D Print Yourself
Maker and 3D printing enthusiast, Mojoptix, has designed a digital sundial that displays time with actual digits! The shape of the sundial was mathematically designed to only let through certain rays from the sun at the right time/angle.
The sundial displays time from 10:00 until 16:00, updating every 20 minutes. As Mojoptix adds, “no batteries, no motor, no electronics… It’s all just a really super-fancy shadow show.” If you’re interested in 3D printing the digital sundial yourself, you can find all of the necessary files on Thingiverse.
