    Hi,

    I don't have a circuit, but I do have a pair of Radio Shack IR headphones. They were about $30. Might be a quick way to solve your problem.

    I'm going to buy these electronic components of electronic market, and then he assembled a ir, but don't know some elements of the above parameters, such as a IC component, only when the 4046, but that is no specific above models, I search on the net also not related instructions. I want to do a microphone, infrared emitting and receiving part, the requirement in 30 meters launch distance, may achieve?
