30 L.E.D. Per Channel VU meter circuit design

I need a simple circuit diagram with component list for a 30 LED per channel VU meter. I plan to have a LEFT CHANNEL readout with 30 increments and a RIGHT CHANNEL readout with 30 increments. I would like to use extra large LED's so the circuit design would need to take this into consideration. I plan to feed this circuit with a "line level" stereo audio input. I need the circuit to operate on 12VDC if possible.

My budget is only $30 for this project. It is just for personal use by me here at home.

Thank You,

I don't expect you to accept this bid. I'd suggest starting with an LM3915 which can be ordered from [url removed, login to view] for about $3. It can run off 12V. The only weird thing is that you need to run 30 LED's, but this de Lagi

Hi, This info is freely available on the web, but if you want a single schematic diagram, I can provide a pdf captured in Orcad for the amount I bid. Thank you for your consideration.
