Help! Building an optical pickup for a bass guitar.
This is what i know so far. There will be an ir led on one side of the string and a photo diode on the other. This will cast a shadow on the photo diode to make an analog signal. One led and one sensor for each individual string. Then I am lost, all I know is that it has to go though an oscillator of some sort to produce the sound.
If anyone could give me a good schematic that would be great.
