Call us easily amused, but we think it’s pretty amazing what can be done with a microcontroller, some RGB LEDs, and a little bit of plastic. Case in point is [andrei.erdei]’s beautiful and quite approachable fiber optic LED lamp. It’s a desktop-friendly version of a similar piece [andrei] made that is roughly nine times the size of this one and hangs on the wall. The build may be simple, but the product is intricately lovely.

We really like the visual density of this lamp — it’s just the right amount of tubes and strikes a balance between being too sparse and too chaotic. As you might expect, there’s an Arduino and some RGB LED strips involved. But the key to this build is in the 16 pieces of side-glow plastic fiber optic tubing. Side-glow is designed to let light escape along the length of the tube as opposed to end-glow, which is made to minimize light loss from one end to the other like a data pipe. This allows for all sorts of fun effects, and you can watch [andrei.erdei] go slowly and soothingly through the different colors and modes in the demo video after the break. Make sure you watch long enough to see the tubes move like the old Windows 3D pipes screensaver

Already have too many knickknacks and wall hangings? You’re missing out on prime real estate — the ceiling. Check out this fiber optic ceiling installation that reacts to music.
