VU Meter Help? Answered

I can only find an LM324 for a U meter. and the only schematic i could find was confusing....http://www.google.com/imgres?imgurl=http://www.zen22142.zen.co.uk/Circuits/Audio/Vumeter.gif&imgrefurl=http://www.acidmods.com/forum/index.php%3Ftopic%3D35382.0&usg=__JKJHEVkfZz92hhYo8rDxJaU9Roc=&h=401&w=407&sz=10&hl=en&start=0&zoom=1&tbnid=BowIq_ZQanGTBM:&tbnh=134&tbnw=138&prev=/images%3Fq%3Dlm324%2Bvu%2Bmeter%26um%3D1%26hl%3Den%26sa%3DN%26biw%3D1440%26bih%3D807%26tbs%3Disch:1&um=1&itbs=1&iact=hc&vpx=124&vpy=167&dur=818&hovh=223&hovw=226&tx=139&ty=123&ei=mrB9TLTbDYSClAffhOjrCw&oei=mrB9TLTbDYSClAffhOjrCw&esq=1&page=1&ndsp=28&ved=1t:429,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.
