LED sound meter

[m.fecho(no spam]

Hello

I am a musician and I am trying to build a sound meter with a large LED
readout. I will try
not to be long winded on describing this one.

I would like a simple LED about a foot long, tri color Red green blue. with the
unit acting as a
sound meter light as you would find on your stereo or a mixing console , only a
larger version
that would be easily seen across a large room.


I have seen such a light at this website
http://www.sunbeamtech.com/PRODUCTS/images/meteor_light_rgb_550.jpg
I don't know if this light completely lights or chases up from one end.

I would like to have the light to have its own sound controler and power
supply, batteries
preferably but plug in would work.

this unit could be callibrated to a sound meter or could have an integrated
sound meter , working
levels of the unit would be about 70 db to 105 db.

TI am a musician in a small band without a dedicated sound tech and throughout
the night as we
are performing our volume may increase , I am thinking that the above unit
would help us keep
this in check and be able to monitor our sound level throughout the night, we
usually do a sound
check before the performance.

If anyone has seen such a unit or know of a LED unit with the soundcontroler
please let me know.

I have seen a DJ with a LED unit complete with sound controler, I looked for a
model number on it
but all I could find was www.sunbeamtech.com He bought it about 2 years ago
and I cannot find
the integrated unit on their website .


If anyone is interested in taking a stab at building a unit such as this please
let me know.


Thanks for any help
