  • I can think of three ways to possibly mitigate ambient light.

    1. I’m guessing a light cover would help block noisy ambient light. I think that’s how the commercial ones work. BTW, the beauty of optical is you can get much lower frequency coupling then electromagnetic – essentially DC, which is why I think the optical pickups were used on Bass instruments.

    2. You might measure the ambient light and subtract it from the string signals using DSP. That would be fun.

    3. You could call the ambient light a feature. Thinking about it, combine it as part of the show. Collaborative concerts. It could pick up movement from light reflecting off the audience.

No public wish lists :(
