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

[Barry Klein]

Wouldn't your effort be better rewarded by making one for Ipad/Android?
(Although there are some already..)

 I have an old hand-held Casio LCD TV and I thout it would be cool to  make
an add-on for it that would allow it to function like a spectrum  analyzer.
I was going to start with some sort of heterodyne system for  the fron't
end, but getting the final output to NTSC video is the  insurmountable
hurtle. It can be monochrome so I don't have to mess with  color. I've seen
projects using microcontrollers that output VGA, but I  like my little TV
idea.

 If I'm not mistaken would the easiest way to do it be to have the TV on
it's side?

 Anyone done anything like this?
