We’ve got three tutorials to help you learn how to convert audio signals to LED light. One tutorial lights the frosted edges of plexiglass. Another uses signals directly from a sound card. Which ever method you choose, the result will be stunning.

This method of converting audio waves into pulsating LEDs involves assembling a premade kit which runs on 110v AC. The LEDs illuminate the plexiglass border of a controller rack. The beveled edges of the Plexiglass create a luminous edge effect. Read.

This would definitely be an awesome addition to any party. Using an output from your computer speakers, you can hook up a few LEDs, and they’ll pulsate to the beat of your music. You can expand upon this and hook this entire thing up to your Christmas lights if you really wanted to. Read.
