What reading solar resistor should i use for transfering sound on a laser for my project?
I have had some success using small pieces (circa 1 cm x 1cm) of silicon solar cell material. The attached pictures are from an instructable I wrote, here:https://www.instructables.com/id/How-to-Listen-to-Light/ This instructable did not involve actually modulating a particular light source, like a laser. Instead I was just listening to signals present, in the amplitude of, various light sources. Another instructable from falconphysics is basically doing the same thing, but with a pre-packaged solar cell module:https://www.instructables.com/id/Cheap%2c-Easy-Light-Probe/

I have seen projects that use solar cells for the receiver. BIGGER AREA AND THE SOUND QUALITY SEEMS ACCEPTABLE - nOT hI fi THOUGH
If you have a choice of device, personally I'd use a photodiode over a photo resistor any day. They are more sensitive, and you'll get better frequency response.
