Vu meter planned

post #1 of 7
Thread Starter 
Im planning to build a Volume unit meter (like the ones on stereos where the little lights light up in towers according to loudness)
I think im gonna use a LM3915/N-1 as my main IC for this.
It is a chip that opens a channel from a main input pin to 1 of 10 output pins to directly light up LEDs in steps of 3db. Im gonna use 2 of these to light up 20 leds on the front grill of my ultra dragon case. Ima connect the input to it directly to my karajan audio module which is included with the dfi ut sli-dr. Its gona b awesome, u just watch people. When im done ima submit the pics and maybe my schematic.... stay tuned!

How are you going to determine the amplitudes to display for each frequency band or does your audio module output this information already?

Im not doing that.
My 'vu meter' is just going to display raw output power.
Im hooking the lm3915 straight up to the speakers. The lm3915n1 lights up 1 led for every 3db raised. Im not going to make separate ones for highs midranges and basses. Lol i dont have enough money for all those damned leds!
Man why r they so darn expensive.... Anyway, so far ive spent 9.93 CAD and i plan to keep it under 10 bucks. I hope i have the resistors and caps on one of the many pieces of crap from garbages all over my hood... If all goes good... This will be the most amazing sub 10 dollar uber project.

Are you using your own design or one of the few premade ones out there(using the lm3915).

Ive seen 2 of them in action before and they look pretty good.

Good luck with this,hope it turns out nicely.
