high power color organ

functionality

A very cool 2 channel Color Organ kit! Lay back and watch high power Leds dance on the music!
  green led indicator for the low frequencies (bass) and  blue led
indicator for the high frequencies (treble)
are attached.A red led dc ok is attached too.The input signal is via a typical female audio 3,5mm connector.
The kit is based on a quad amplifier (LM324).

Just drive an audio signal of an analog output (e.g. soundcard) direct to the audio jack of the kit.

Use an audio splitter if you have only one output.The cable can be both mono and stereo.
The audio signal now is ready to travel through the opamps.But first of all it must pass through the potentiometer to choose the audio level.

The 2 first opamps of the LM324 are active filters that separate the low and high frequencies.
The other 2 opamps are amplifying the separated signals separately.

Now the new signals trigger 2 high power n-channel mosfets irfz44n ,one for the low frequencies

and one for the high frequencies.The mosfets can sink currents up to 4 amps.Attach a heatsink if you notice too much heat on the mosfets.
Wide input-output voltage range 5-24 volt dc.


Control high power led lights or motor or fans with this kit and make them react with the music.

how to drive one channel of your soundcard output to the kit

Split your audio signal

Picture
If your soundcard doesn't have more than one output you can split the audio signal with a simple audio splitter!
So you can here the music while seeing the leds dancing!
If you have more than one outputs you can take one free output directly.


Use a male to male audio stereo jack cable.

Picture
        Now simply drive the cable from spliter or soundcard
        directly to the female audio jack of the color organ kit.
       

Troubleshooting

Picture
If you cant see the leds dancing one of the following may be the cause:
The audio signal is too week-->Increase the volume of the device
The audio signal is good --> Adjust the sensitivity of the trimmers


Choose the way you want to operate the kit!
Use it as a dancing lamp

or as concealed lighting color organ!
