Sun Clock with Numerals

Digital Solar Clock Project

Solar clocks with numerals combine the ancient principle of sundials, modern digital technology, and 3D printing. A French enthusiast and blogger known as Julldozer, showcased a digital solar clock project to the world.

Solar-Powered Innovation

These clocks operate without electricity, relying solely on precise calculations and physics. To use them, simply place them in the sun facing north. The unique system of small slits on the casing allows the time to be displayed in numerals through the shadow cast by the sun on the clock, depending on the sun's position.

The design of the openings was created and turned into a 3D project by the author, available for download and printing. You can create your own clocks or share the link to the article on social media to introduce the concept to your friends. However, Julldozer notes that the device is likely only manufacturable using a 3D printer. By the way, we recently explored an interesting invention – pens that draw in three-dimensional space. The internal structure of the slits is quite complex for standard methods. The author recommends making the clocks from a plastic that can withstand direct sunlight exposure, such as ABC plastic.

For Southern Hemisphere Residents

For residents of the southern hemisphere interested in creating similar clocks, the author advises using a 3D editor to display the project design upside down. These clocks should be positioned with the south pole instead of the north.

If you don't have a 3D printer, you can obtain these clocks by ordering them online from the developer. If you are considering coming up with your own business idea, read this article, which will guide you on how to do it correctly.
