Guest puzzled Posted April 7, 2013 Report Share Posted April 7, 2013 Hello, I'm looking for a project that may at one time been listed on this site: Voice Activated SwitchThe diagram was re-posted here: http://www.hobby-circuits.com/circuits/sensor/sound-sensor/443/voice-activated-switchI'm a beginner & not clear on all the parts needed.There was a description & a link back here. It began thus: "This circuit uses an MC2830 to form a voice activated switch ( VOX ). A traditional VOX circuit is unable to distinguish between voice and noise in the incoming signal. "Thank you for your time. Quote Link to comment Share on other sites More sharing options...
audioguru Posted April 7, 2013 Report Share Posted April 7, 2013 The MC2830 IC is obsolete and has not been made for many years. Quote Link to comment Share on other sites More sharing options...
