When it comes to technology, a sundial isn’t exactly cutting edge. This example is an exception. Using the latest 3D printing technology and a computer model, French maker Mojoptix has designed a deceptively simple digital sundial which lets light through perfectly angled holes to write out the time from 10:00 to 16:00 in 20 minute increments on the surface below.
In the spirit of maker culture, Mojoptix has shared a tutorial detailing exactly how his sundial works, how it was designed and how to build one yourself in the cartoon filled video down below. He’s also shared the files necessary to print your own (in something around 30 hours) over on Thingiverse.
Don’t have your own 3D printer? You can purchase a complete digital sundial on Etsy for just €69.00.
Here’s a timelapse of the sundial in action:
