After he’d just finished a project using RGB LEDs, Imgur user nolobot’s brother mentioned he needed a new computer desk. Most people would probably just let their brother buy one, others would make something out of wood, but nolobot instead decided to create something truly amazing using more than 1,200 WS2812 RGB LED modules, an Arduino Mega, aluminum extrusion, and translucent polycarbonate.

The Mega controls these LEDs with the FastLED library, which are sandwiched between a base piece of plywood and a strip of polycarbonate using custom spacers. This diffuses the light nicely, allowing for beautiful light animations directly on the desk’s surface.

You can find more on this awesome build on the project’s Imgur page!

A proper battlestation — or more colloquially, computer desk — setup can sometimes use a bit of technical flair to show off your skills. [fightforlife2] has shared their DIY ambilight monitor backlighting that flows through different colours which mimic what is displayed on the screen.

[fightforlife2]’s setup uses fifty RGB LEDs with individual controllers that support the FastLED library, regulated by an Arduino Nano clone — although any will suffice. The power requirement for the display was a bit trickier, ultimately requiring 3 amperes at 5V; an external power brick can do the trick, but [fightforlife2] also suggests the cavalier solution of using your computer power supply’s 5V line — adding the convenience of shutting off the ambilight display when you shut down your PC!

Ambilight Frame Setup

Connecting the LEDs to the Arduino is simply done, followed by adding the FastLED library and installing and configuring AmbiBox on your PC. For gaming, the software only works with borderless windows for games, but that puts a 5-10% tax on your processor. Be forewarned! — the ambilighing can be distracting when gaming for the first week or so.

If you want to carry this cool idea over into your other pursuits, you can — for example — set up a similar display around your piano.
