I recently came across this on instructables.com:
https://www.instructables.com/id/Build-the-MS-Alice-Stereo-Microphone/Looks like a fun project...I have the schematic here for the internal circuit (this build utilizes 2 of these circuit boards), maybe someone can create a nice compact vero layout that will accommodate the aluminum mic housing...anyway, here it is!
EDIT: There is also a more simple condenser microphone build (from the same guy) that uses the same circuit (only 1 board as opposed to 2 as mentioned above) here:
