Greetings everyone;
I am a general geek looking for a way to get this basic Audio to Light modulation circuit to run from straight line level from a small cd or mp3 player.
My problem is the input here requires about 2 volts from the source to trigger IC1. It generally uses a speaker output which is then calibrated at RV1.
Is there some way I can modify the input portion of this circuit to be line level friendly. Or a way to easily step up the line level voltage to work here.
The challenge of course being that I want to keep the circuit small & simple if possible. I have built one with a small audio amp but with the power supply it required it became to bulky & complex(possibly due in part to my lack of knowledge).
Any ideas?
