There’s something about the regimented square shapes of the IKEA Kallax shelf that convinced [Eike Hein] it could benefit from some RGB LED lighting, and while he could have simply used a commercial solution, he decided instead to develop Hyelicht: an incredibly well documented open source lighting system featuring multiple control interfaces and APIs. We’d say it was overkill, but truth be told, we dream of a world where everyone takes their personal projects to this level.
In the boilerplate configuration, [Eike] shows off controlling the LEDs using a graphical user interface running on a Waveshare 7″ touch screen mounted to the side of the shelf. That’s the most direct way of controlling the LEDs, as the touch screen is plugged into the Raspberry Pi 4B that’s actually running the software. But the same interface can also be remotely accessed by your smartphone or desktop.
You can also skip the GUI entirely and control the LEDs with a command line interface, or maybe poke Hyelicht’s HTTP REST interface instead. The system can even integrate with the Philips Hue ecosystem, if you prefer going that route.
The 5×5 Kallax shelf is the project’s official reference hardware, but of course it will work with anything else you might wish to cover with controllable LEDs. We’ve seen similar setups used to light storage bins in the past, but nothing that can even come close to the documentation and customization possibilities offered by Hyelicht. This is definitely a project to keep a close eye on if you’ve got the urge to add a little color to your world.
