Once the circuits are wired up, any interruptions of light between the infrared emitter and detector diodes will generate a corresponding audio signal. In this case, the pluck of a string will convert light into sound!
We start by making a breadboard version of the basic audio circuit. We then multiply this circuit to accommodate four inputs, or strings. Interestingly, the color and material used for the strings produces slightly different sounds. Feel free to experiment with this! Also, feel free to experiment with the look and feel of the guitar. Since the actual body and shape of the guitar don’t effect the output like an acoustic guitar, you can mount this circuit onto whatever chassis you want. Build frets for your guitar, make an upright bass or slide guitar, and design a custom case to put all your hardware in!

Actually if your detector has high enough resolution to convert string movement to audio signal with enough fidelity, you will find out that the body material will make a difference. Find out how different woods in a solid body electric bass affects it’s tone.
is there different to commercial systems? http://lightwave-systems.com/
Why buy it when you can MAKE: it?
Is there a better amplifier circuit i could use to get a better sound?
hi TDev, the LM386 was employed because it only requires one 9V battery. I’m curious what type of sound you’re currently getting, and what you don’t like about it?
Hey Nick, I havent actually built it yet and im researching a number of projects but i was just wondering if anyone went further with this and what results they got, for my project it would need to be a bit more advanced circuitry wise.
Beats reportedly named the project “Daisy” honoring what it called the primary digital, computerized song. At the time, it said in a news release that the service would likely “bring an emotional connection time for the act of tunes discovery, ” referring to the method through which users come across, buy and consume songs.
