LED Matrix Clock Puts Its Inner Wiring on Full Display

A striking clock by maker Roberto Alsina embraces transparency instead of hiding its electronics. Rather than concealing wires and components, the design proudly exposes them, turning the internal hardware into a key part of its visual appeal.

The only parts kept out of direct view are the LED matrix panels. These sit behind a thin red cover, allowing the light to shine through evenly when the clock is active. The result is a clean, glowing display that contrasts nicely with the raw, exposed wiring behind it.

This version is an evolution of an earlier design. In the original build, all components were enclosed in a traditional case, but the creator found it lacked personality. The new approach flips that idea, taking inspiration from classic clocks that showcase their inner workings.

At its core, the build is relatively simple. A Raspberry Pi Zero W acts as the brain, paired with LED matrices and a mostly 3D-printed structure held together with standard hardware. The creator has also shared the files and code, making it possible for others to replicate or modify the design.
