In the second half of the twentieth century, homemade color music was a favorite pastime of several generations. Nowadays, when it has become fashionable to remember the twentieth century, enthusiasts are again building household color music installations.
Instructions
Step 1
Get about three watts of low-cost active computer speakers. Pay attention to the fact that inside one of the speakers there is a power supply and an amplifier, while the second, of the same size, is almost empty - there is nothing but a speaker inside it.
Step 2
Disconnect the speakers from the computer and lighting network. Only open the case of a speaker that does not contain any electronic components inside. Remove the dynamic head from it. Take a light bulb from an unnecessary Chinese-made Christmas tree garland. Remove the light bulb only when the garland is unplugged. Connect it in place of the speaker, then place it in front of the grille so you can see it.
Step 3
Set the volume to minimum. Connect the speakers to your computer and network. Start playing the melody. Gradually increase the volume until the light starts blinking in time with the music. Do not set the volume too high so that it does not burn out.
Step 4
If you are not satisfied with the single-band color music, make a three-band one. Take three bulbs from the same garland: red, green and blue. Connect the red one instead of the speaker through any large choke you have (the main thing is that it fits into the speaker case), the blue one - through a paper (not electrolytic) capacitor with a capacity of about 10 μF (before installing, make sure with a voltmeter that it is not charged), and green - through a series-connected inductor and capacitor. Then check that the red light flashes for low frequency sounds, green for midrange sounds, and blue for high frequency sounds.
Step 5
Keep in mind that your homemade music setup works in a somewhat unusual way. Now you hear the sound of only one channel, and the color picture is synthesized by the set-top box completely from the signal of the other channel. Do not be surprised at the occasional slight color mismatch with the color of the sound, as the signals in the channels may differ.
