    I'm looking for a schematic for a LED light organ. What i would like to do is a circuit that senses (using a mic) bass-beats and flashes some LEDs. The guides I've found so far are quite complicated and uses AC (i want it to be battery driven)
    Any ideas?

    Another thing i would like to do is to use a photoresistor (?) to control some LEDs. (light the led:s when is is dark)

    This is my first post, and I'm a bad-spelling swed, so please be gentle. :)

    Welcome to the boards.

    You don't say if you want a purely sound-driven or software driven light organ, so here's both I suppose..

    The software of choice is a Winamp plugin unfortunately names Discolitez. The site has plans for hardware that works with the plugin.

    A standalone light organ is a pretty widely available schematic:
    Velleman kit
    DIY

    And there's lots of variations depending on whether you intend to drive LEDs or incandescent light bulbs with it. Have fun.

    Thanks for the answer. The device I had in mind was a stand-alone organ, using a microphone (like the cheap ones ones that comes bundled with soundcards) to detect sounds.
    The velleman kit seems to be using a loudspeaker input(?). (and I would prefer to make one of my own, and not as a kit :) )
    The other one have I allready found, but I could not make much out of it since i don't know how to convert it to 2-5V DC and LED:s.

    If anyone has (or can make) a schematic for something like that I would be very glad. :) I guess it's would not be that hard to figure it out if i had some knowlengde in electronics, but I don't :(

    I installed the velleman kit (2x 10 LED VU meter) in my case, works like a dream.
    I used a 3.5 mm stereo -> 2x stereo splitter cable, so the signal from the soundcard goes to my speakers as well as my VU meter.
    The kit has an adjustable sensitivity which is regulated by a small potentiometer on the print (1 for each print), but i used a stereo-potentiometer which I installed in my front to easily adjust the sensitivity :)

    Here's some pics of the installed VU meter, and also what is looks like fully assembled (quite a wire mess)
