VU Meter Help?

I can only find an LM324 for a U meter. and the only schematic i could find was confusing....,r:0,s:0.....
So if someone could either explain that circuit or help me with a new one, I'd much appreciate it!

look at many of the lm3915 vu meter circuts online, ncluding some availible here
That circuit is a way of building what you can buy in one package from a lot of bits. I suggest you look for the "LM3915" which is a chip designed to drive LEDs as a VU meter.

Is that part only available for online order? or is there any household appliance i could take apart to find one? Thank you
. If you want a VU meter, it will most likely be in a piece of audio equipment (stereos, audio amplifiers, tape recorders, &c). Off the top of my head, I can't think of a use for a VU meter outside of the audio industry.
Dunno. I don't know where you are in the world. Radio Shack MIGHT do them in the USA.
