Grad Gown LED VU Meter

You may remember the Grad Cap LED Hack that we had here last year, this Grad Gown LED hack uses a bunch of LEDs that are connected to an audio detection circuit that makes it into a VU meter! It is one of the entries in the Curious Inventor Contest, this is the last day of the contest so hurry to get an entry in.

"I had an idea for a while to build a VU meter into a tie or T-Shirt. I decided to kill two birds with one stone by building the VU meter into my graduation gown. The end result was 10 super bright blue leds lined up the front of the gown."
