 Here is the website talking about this style microphone http://atransc.org/techniques/techniques_optical_microphone2.htm

I guess it WILL pick up "lcd computer screens" too.
Since it will also receive normal light and ultraviolet as well as Infrared light sources....(LCD's do not transmit infrared).

I purchased 2 more IR Photodiodes and 2 - 1/8" (3.5mm) connectors (mono) today so I can make a few more....the numbers given in the discription for the Radio Shack stock numbers...are different as of today. They are 276-0145 (has a "0" in place now).
