In this video I demonstrate how a solar panel can turn light waves into sound, by attaching the panels output wires to the input of a telephone amplifier. For those who are interested in making a project like this, please note that not all amplifiers will worked well with this set up, but these older telephone amplifiers worked great.. One other point I should explain, his how I'm able to light up the two LEDs (Light Emitting Diodes) with just an antenna and a ground wire. I live about a mile from two AM radio stations, so I'm able to pick up enough power off my 200 foot long wire antenna to light up the LEDs, with no problem. Also note that a 1N5711 can replace the 1SS86. It's not as sensitive as the1SS86, but it works in case you can't find the original 1SS86 diodes made by Hitachi. There are many fake 1SS86 Diodes out there that may work, but not as well as the original Hitachi 1SS86 Diodes.
