[sdiy] Making an audio spectrum analyzer from an old Casio LCD TV

[aankrom]

 Perhaps, but I /have/ the LCD TV. I may just end up using it as a 
 receiver for a remote controlled ATV ATV using one of those A/V 
 modulators that transmit on channel 3 or 4. But the spectrum analyzer 
 idea seems like a cool one. I KNOW how to do it using an oscilloscope. I 
 have a dual trace with Z-axis input and delayed synch/trigger. I don't 
 think the Z-axis is so important but the delayed synch/trigger si the 
 key to converting the time domain into the frequency domain.
