The Creation of the Digital Sundial
In 2015, French engineer and maker Mojoptix designed a revolutionary digital sundial. Unlike traditional sundials, this invention casts shadows that display the time in digital-style numbers. It does so without electronics, relying solely on sunlight and precision engineering.
How It Works
The digital sundial uses intricate 3D-printed patterns with carefully calculated holes. As sunlight passes through these holes, it creates a shadow that forms numbers on a surface below. The sundial updates every 20 minutes, displaying the time in a way that merges ancient techniques with modern design.
A Global Phenomenon
Mojoptix shared the design online, allowing anyone with access to a 3D printer to create their own digital sundial. The open-source nature of the project attracted enthusiasts worldwide, sparking interest in the intersection of technology and traditional methods.
A Unique Timekeeper
The digital sundial functions best between 10 a.m. and 4 p.m., under direct sunlight. Its accuracy and visually striking design have made it a popular conversation starter and a celebrated innovation in combining historical principles with cutting-edge tools.
