Infrared Voice Transmitter Circuit
This is a highly unique Infrared voice transmitter circuit. It is used in situations where an RF transmitter can not be deployed, such as in clandestine operations. All sounds, including conversations are picked up by the electret element, amplified, and then through thru an Infrared Diode.
Most Infrared diodes will work. The Infrared light waves are picked up by an Infrared receiver up to 200 feet away. The total current consumption of this device @ 9 Volts is 20 Ma.
