| 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. |

| 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? | ||
| what is exactly this J1 J2 J3? how is the connection of resistors R10,R7&R11,R8&R12,R9 | ||
| 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) | ||

| 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 ;) | ||
