Beautiful DIY Ambilight Display

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!

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.
