Musical light show is far less complex than you might think

[Matt and Jason Tardy], who make up the musical performance duo known as AudioBody, were recently featured on Make: explaining how they put on one of their trademark segments. The most popular portion of their show features color changing tubes of light which the pair spin and fling around not unlike a higher-tech version of the Blue Man Group. While the visuals are pretty slick, the technique behind it is far simpler than most people initially imagine.

As you can see in video below, the tubes look to be nothing more than simple white lights. As the brothers work through their performance however, the tubes switch from white to blue and back again with a liquid-like transition between the colors.

The [Tardys] say that most people peg a microcontroller or other complex electronics as the source of their light wizardry, but the real answer is much simpler. Embedded in the end of each tube is a bright LED flashlight. A sliding blue filter positioned inside the tube provides the silky smooth transition between colors – no fancy electronics required.

If you would like to see how they were built, be sure to swing by the AudioBody web site for a how-to presentation by the [Tardys] themselves.

    Brilliant! Why use a complicated, electrical solution when a simple, mechanical one works?

    Apparently the poster of the video doesn’t like negative feedback so they censor it. Good job commies.

    Not sure what the bitching is about, looks like I missing the fun. Anyway, video looks alright. WIth some better music it might even be an enjoyable video.

    Did HaD even watch the video? That’s not how it works. The tubes have an led flashlights at each end, one is filtered blue. Then there’s a ball in between the two that rolls back and forth blocking the light.

    Its just crappy executed poi moves. Add some programable POI’s or juggeling balls into the fray an you have a million times better result than this…

    these tubes would make great underglow for cars that change color when you stop and then go again. very cool

    That’s pretty sweet! A ton of well put together ideas on their site. Am sure we’ll hear more from them cause they are actually using the type of tech us nerds make.

    I’m just wondering how many times they’ve popped each other while practicing!
