Headphones audio level meter -- EL wire decoration

[yardleydobon]

I modified an inverter to react to the audio signal from my mp3 player instead of sound. The inverter drives a EL wire decoration on my headphones that looks like an audio level meter. So when I listen to music on my headphones the EL wire shows the world how much I'm damaging my ears!
