Light to Sound Wave Receiver using IC 741

This be Light Wave Receiver circuit , perform take sound signal from the light by modify from the light into pieces hear at a loudspeaker. By the circuit uses LM741 , be IC op-amp the multi-purpose IC. It use for enlarge sound signal , change the way Photo transistor into pieces give hear loudspeaker way well.

Sound Light 650Watt Lamp Flasher

This is Sound Light 650 watt perform change sound of side music input be Lamp Flasher follow the level sound tone. Which there is 3 the level together , be the pitch is low. The sound is middle and tall sound. By each the group applies to ac lamp at use force against 650watt not exceed electricity and LAMP that use 6.3V or friends will use 12V sizes all right. But must use power supply 12V AC with. Besides SCR that use must durable current get tall about 4A with. The detail is other , a friend can see in the circuit yes.

Color Organ

I have had many requests for this circuit. It was a very popular unit years ago. The basic idea of the project is to make different colored bulbs light at different frequencies of music. The circuit connects to the speaker outputs of your stereo or to the back of your speaker. The music passes through the transformer and the volume level is adjusted by the 5k ohm pot. Each light bulb is turn on by a different frequency of sound based on the resistor & capacitor combination in the gate circuit of the SCR. If the resistors R1, R2, or R3 are changed, the frequency of sound that will trigger the SCR will change. The isolation transformer is for protection.
