Demonstrate the heart of Cell Phone and Wireless Communication modules! This clever demonstration shows how your voice can be sent on a light beam through the air or through optical fibers. This is an important concept since all smart phones and computer systems send digitized, encoded radio signals to the nearest towers. This circuit, together with a microphone transforms your voice into vibrations of the LED light. By pointing the light at a solar cell and mini-amp you can transform the blinking light back into a high quality sound. Bias Circuit Board includes superbright LED and 9 volt battery.
