You’ll convert light to sound in this Weekend Project. Using the LM386 amplifier, and pairs of infrared emitting and detecting diodes, we’ll show you how to build a four-string optical bass guitar. Mount your hardware onto a piece of lumber, or build your own classy chassis. Then, get ready to rock!
