Analogue Gauge Readout For PC Audio
How can I use 2 of the "Cracker Box Amp" circuits to drive standard analogue gauges from the audio out on my computer. I will use 2 gauges, one for left channel and one for right. I want the gauge to show the amplitude.
If I just wire up a gauge to a channel on the audio out then the needle will simply move as if it were a speaker. As I said before, I want the gauge to show the amplitude.
