Can you make small blinking light into large blinking light --YES!!
Top left 900 Hertz input is music from HI-FI 16 ohm speaker system.
Low frequency cutoff is through 3 mH coil to 47 bulb, with NE-2 high frequency cutoff on right and Light Dependent Resistor (LDR-25) on left to turn on 25 watt Red bulb. LDR-25, 47 bulb, NE-2 is in metal light tight container as one group.
Middle frequency cutoff is through two 50 uf capacitors and 1.2 mH coil to 47 bulb, with NE-2 high frequency cutoff on right and Light Dependent Resistor (LDR-25) on left to turn on 25 watt Green bulb. LDR-25, 47 bulb, NE-2 is in metal light tight container as one group.
High frequency cutoff is through two 20 uf capactors and to 47 bulb, with NE-2 high frequency cutoff on right and Light Dependent Resistor (LDR-25) on left to turn on 25 watt Blue bulb. LDR-25, 47 bulb, NE-2 is in metal light tight container as one group.
Aluminum plate .25 x 4.25 x 7.0 , all in inch measurement, is heat sink mount.
Popular Electronics, March 1965, page 43, article about Color Organ, gives variety of light refracting, blending, and bending ideas. Rough idea is shown simulator.
