== Giant LED VU Meter ==
This i see as something we can assemble and sell to local clubs and maybe use for our own parties. I'm thinking large scale and go from green to yellow to red so there would be no need for RGB LEDs just wire a line of 4-5 leds and have that row display when the music reaches a certain volume.

Here is a link using a piezo to measure the volume of the music: http://www.nerdkits.com/videos/sound_meter/

The LEDs would be fairly cheap. Using this image as a template: http://www.enote.si/studio/images/vumeter.gif. If we say on average $.6 per LED, which looks a bit high but bear with me. 8 rows of 5 green + 3 rows of 5 yellow + 3 rows of 5 red = 70 LEDs * $.6 = $42 per VU Meter + cost of microcontroller ~$30. So a set of working VU Meters to put in a club would cost us ~$114 and if sold for $200-$300 we could make a nice profit while still learning and teaching.
