Stereo Microphone in a Mint Tin
Francisco said: "Two microphone capsules salvaged from old computer microphones are glued to the enclosure at about 150 degrees (the holes were milled with a dremel). Both microphone signals are then amplified by the Stereo Microamp circuit. The capsules need dc bias, so the input of the circuit is modified a bit to accomplish that. The whole reason for making this microphone was to be able to record easily on my minidisc, which doesn't have a MIC input. It does, however, have a LINE IN jack which the amplified mic output connects to."
