My friend just called and had this idea for his band, they want to have a few TV's on stage when they play and on them they'll be playing old Public domain horror movies and stuff, he was wondering if there was any way that if when they play louder they could get the video to kind of wobble/get staticy. Is there anyway to do this?
I saw this done with something before. All you need to do is get whatever your using to play the movies, hook the video out into a box, and then from the box into the tv. What you do in the box is up to you but i have one idea.
1. Find a distortion pedal or something that is designed to change a sound.
2. De house it, put it in the box.
3. Remove the pedal pot and replace with photocell.
4. Get an audio- out from your instruments and hook it up to an led (may require a resistor)
5. Tape the led and photocell together with electrical tape.
THERE YOU GO, The tv will get distorted depending on how loud you play.
Cost: However much a distortion pedal costs +$15!
