This is a simple, one lamp colour organ. It is far less complicated then the Three Channel Colour Organ. It is simply a lamp controlled by an SCR. It can be built in a few minutes, and combined with other circuits to make some pretty neat effects.

Schematic

This is the schematic of the Simple Colour Organ

Description
Substitutions
R11500 Ohm Pot
T11500 Ohm/500 Ohm Matching Transformer1K/1K Matching Transformer
SCR11C106Y SCR106B, Teccor S2003LS1
L1110-100 Watt Lamp
MISC1Case, Board, Socket For L1, Line Cord

Notes

  1. L1 can be any 10-100 Watt lamp.
  2. R1 adjusts sensitivity. The greater the resistance, the less sensitive the colour organ becomes.
  3. Since this project is powered by 120 VAC, it must be installed in a case.
  4. You can also use the Teccor S2003LS1 SCR for SCR1. These give better sensitivity and brightness than the C106Y units.

teh mic connects to the unused side of the matching transformer, as the mic changes the inductive field of the transformer, the secondary coil then changes the bias of the triac...

How would sound activation be integrated into this circuit? ex. sound in mic = to patterns in lightbulb

The secret to understanding electronics is to understand each part and what role it plays in the circuit. Of each thing you see in a circuit, ask: "What to I expect to put in and what will this device do with it." If you can answer that, the circuit is self-explanitory. If not, educate yourself. Don't expect everything to be handed to you with a ribbon.
