Minivox Voice Operated Relay Kit

Voice opererated relays are often used in ³hands free² communication such as mobile radios, amateur tranceivers as well as some PA applications. The idea, of course is that instead of pushing a button on the microphone to talk, the sound of the voice activates it instead. This tiny kit measures approx 50 x 50 x 15mm and is designed to fit into the tightest spaces, has almost no turn-on delay, and has 3 second release time. 12VDC @ 35mA required. Kit is supplied with PCB electret mic, and all specified components.
