[Noteolvides] creates the CubeTouch, a cube made of six PCBs soldered together that creates a functional and interactive piece of art through its inlaid LEDs and capacitive touch sensors.

The device itself is connected through a USB-C connector that powers the device and allows it to send custom keyboard shortcuts, depending on which face is touched.

The CubeTouch is illuminated on the inside with six WS2812 LEDs that take advantage of the diffusion properties of the underlying FR4 material to shine through the PCBs. The central microprocessor is a CH552 that has native USB support and is Arduino compatible. Each “planet” on the the five outward facing sides acts as a capacitive touch sensor that can be programmed to produce a custom key combination.

Assembling the device involves soldering the connections at two joints for each edge connecting the faces.

We’re no strangers to building enclosures from FR4, nor are we strangers to merging art and functionality. The CubeTouch offers a further exploration of these ideas in a sweet package.
