So, while winding down my weekend of crazy children and weddings, I remembered that I hadn’t posted my blog yet! For the upcoming solo project, I’ve decided to discuss the uses and barriers of using the Photophone, first used by Alexander G. Bell on April, 1880. The photophone uses sunlight, then, with a thin mirror which flexes as the sound waves from your voice hit the back of it, it transmits the light waves to a receiver which then reconvert the light waves to sound waves. This is considered the first wireless telephone call and a precursor to modern fiberoptics, which use light to transmit information in much the same fashion.
My only barrier to information at this point is the fact that the photophone was a short lived project. Fog, clouds, and snow all played a part in disrupting the signal from the photophone, and since cabled telephones became all the rage just a few years later, little was written about the device. I have found the four patents filed for the photophone, along with some era specific illustrations demonstrating the use of the photophone. There are also a few secondary sources in the form of scholarly books available on google books. I do feel comfortable that with the number of sources I have, I should be able to produce a 500 word project without a hitch.
