Hi, I'm currently an art student at the University of Houston, and I've run into a bit of a roadblock.
I'm working on an installation in which an audio signal from a headphone jack will be sent to an A/V Receiver Unit. From the A/V unit, the wiring for the left speaker will be hooked up to the pos/neg connections from an old air compressor (12v dc). In theory, as the audio signal fluctuates, the voltage sent through the speaker wires will power the air compressor. Louder sound = Higher voltage = More air through the compressor.
I've only done similar experiments when playing with old tube televisions, and turning them into o-scopes hooked up to audio signals. From what I figured, I was easily able to get around 10 volts from a small radio.
Ok, here are my questions.
What is the standard voltage output range going from a home receiver unit to an 8 ohm speaker?
If I'm able to achieve the proper voltage to power a 12vDC air pump, will there be proper amperage? If not, what can i do to compensate?
And lastly, if I am able to get the proper amount of power, will the fluctuations in voltage have a damaging effect on the pump itself? Or will it simply act as a relay, powering on and off as the voltage/amperage is reached?
Thanks so much for any help!
