This project is a photo-tremolo with weird polyrhythms instead of a constant warble like a normal trem. The unit is just a prototype. I decided it needs a preamp to boost the signal, but it sounds great with other effects that boost its signal like a fuzz pedal or overdrive. I also need to figure out a bypass switch and some way to kill the battery when you are not playing. I think it could really be a sellable device with a unique sound. It took me 4 attempts to solder it before I could get it to work. I discovered heat shrink during the process which cleans things up inside the box and prevents shorts. Modern hairdryers do not get hot enough to shrink the stuff very fast though. I may invest in a heat gun. The cool thing is the internal led circuit which changes the photo tremolo effect is a circuit I can also use to make a cool expression device. I might try that too. I am really happy with this!
