Thread: VU meter for sound help please




  1. #1

    Default

    I was wondering, is it possible to have a set of maybe 8 to 12 LED's on either side of the fron of a case with each set hooked up to the speakers or soundcards (eg left side set to left channel) so that each set works like a VU meter for any sound coming from your speakers?

    If so, could someone tell me how to do it please, better still a schematic.

    Thankyou

    I guessing its kinda like the thing you get in most stereos? I remember I had quite a old one like that. I'm not sure how you would go about it though. I guess if you got desparate you could always try and find a old hifi that has one of those meters and pull it to bits

    This looks like an interesting mod, was going to attempt myself a while ago. I think Dick Smith might have some kits that you can build. I'll check it out for you.

    EDIT: I checked Dick Smith and couldn't find the kit. I'll try Jay Car, I think they have a larger range of kits

    Seems that Dick Smith stopped making them at the end of 2000.
    And I couldn't find anything on JayCar.

    I ran a search on Google and came up with this store in Queensland selling a VU kit for $25.

    Bought the kit myself today (K 2637), just finished building, and I'm telling ya, so far it looks pretty sweet. Got it going stereo. Kit cost $13 for each one, two needed for stereo mode.
    I'll get pics when I place in a drive cover.

    How did you connect it to the soundcard or speakers though?

    I had a double adaptor for the output for the soundcard, so basically I can plug two headphones into the one socket. And as for the VU meter itself I used a 3.5mm male stereo plug.

    So the VU unit has a 3.5mm male connector coming from it going to the back of the computer to the double adaptor for the sound card.
