Any sound vibrates the wide flame of the oil lamp. The solar panels convert this vibrated light back to an analog electrical signal. My first designs date back to 2004. Also search for "optical microphone" on Google to see the articles I wrote for AA-EVP on the subject. http://www.youtube.com/watch?v=j5-WOuWPHOY Dave Last edited on Sep 27th, 2009 08:08 PM by EVPDave |
