The QuadClock Bricta
This clock shows time through four nicely sized displays in a brick like case - one digit per screen. You get a nice selection of fonts to match your style, adjustable through a rotary dial. There are no apps to install, no accounts to create, and no required Wi-Fi signals. What makes it different? It does one job without excuses: reliable timekeeping you set once and trust to work like your microwave or toaster. Simple, visible, and permanently offline.

Choose your color
Right now there are four different colors available. On the basic black version, the displays blend in beautifully. The wood version (while still made of PLA with added wood fibers) gives it a more natural look. The red granite version has a slightly rougher texture for a more organic feel, and the green version has a mossy, rough finish. They all look great!
Why did I make it?
I wanted to create a product that I could design from the ground up. I invented this clock because I had never seen a design like it before, and I liked the idea of making it available to others. Recently, I spent three months refining the concept of the QuadClock. It was an exciting process—creating the schematic, designing the circuit board, developing the software, modeling the case, and putting together the documentation.
The software is fully open source, so you’re free to modify or enhance it as you see fit. If you have a contribution, feel free to submit a pull request on GitHub, and if appropriate, I’ll merge your additions into the main branch.
Important to know
While it’s not hi-fi or particularly loud, the speaker produces enough sound to wake you up if you use it as an alarm clock. You can opt for a better speaker, but as expected with a small plastic case, the sound quality is still similar to an old transistor radio.
This item is 3D printed at home, so minor variations in finish, fit, and material quality are to be expected.
While I strive to make the clock as polished and well-made as possible, it’s still a project handcrafted by a hobbyist, not a mass-produced product. Every detail has been carefully considered, and I’ve put a lot of passion into the design. I hope you’ll enjoy using it as much as I enjoyed creating it!
