Hi, I am currently working on a little science project, I came across this page about sending audio signals through a laser pointer. http://www.i-hacked.com/content/view/162/44/ [Broken] I was wondering if it is possible if I did it with an ordinary light bulb. It said that the data is transferred by the light's amplitude, so if I were to use a light bulb instead of a laser point, does it kind of mess up the signal if I were to stand closer or farther from the receiver? Or does the audio output on the receiver will just have a lower volume if I stand farther away? Thanks.
