Stereo microphone in a mint tin
Step 1: Overview

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 acomplish that.
Control panel includes: Power switch (can be replaced with a switched jack), Gain control (stereo pot to set the amount of amplification needed), 1/8" stereo jack (this is the output).
