Anyone who has been to a night club, concert or school dance has probobly seen a colour organ. Colour organs cause lights to blink and flash to music from your TV, stereo, guitar and even your own voice. The colour organ presented here needs no connection to the sound source, it picks up sound from its built in microphone.

Notes

  1. R10, R11 and R12 control the response of the different lights.

  2. The circuit can handle up to 300 watts per channel.

  3. This circuit is NOT isolated from the 115 Volt line. If it is used with the case opened or not installed in a case, you could recieve a bad shock or be killed.

  4. You can also use the Teccor S2003LS1 SCR for SCR1. These give better sensitivity and brightness than the 106B1 units.

  5. Thanks to James Maloway for redrawing the schematic.

Can a 10K:10 ohm-audio transformer be used? If not, what can I do to increase 10 ohms to 600 ohms without changing any other values?

Is there any way to make them more responsive. I made a 120v one and compared to my friends, who made the same thing, It takes a larger audio input signal. For an input, I used compression terminals that connect to the audio transformer (Mouser 42TM114-RC)

Is there a way where instead of there being a mic for your sound input that you could wire either rca cords or like 3-4 3.5 jack inputs for your sound and if so what are the schematics of it....thanks for your time and please email me back

Could you upload the 12v version for everyone to see?

correction: DC version with SCR (thyristor) wont clear lights after triggered once. Use a transitor instead, no clue what type is best

Changes for 230 V AC Version: C1 & C2 = 22µf 500V Electrolytic Capacitor R1 = 100k 1/2 W Resistor Q3, Q4 & Q5 = C106D or S4003L Changes for 12 V DC Version: remove C1, C2 & R2 replace D1 & R1 with a wire connect +12V on top (common at bottom) use 12V bulbs ;)
