Finally: How to make stereo mics

It took a couple of hours in this world of instant information but I finally got some simple information on creating a stereo microphone for my voice recorder. Go here to get the full details including schematics:

The TRS connector has 3 sections on its tip: left and right channel signal input, and ground. To make the stereo mic, all one has to do is:
1) Join the ground wires on the electrets together and connect them both to the GND of the stereo plug.
2) Connect one positive electret wire to the left channel of the stereo plug and the other electrets positive terminal to the right channel of the plug.

Easy as pie. I haven't used it much but I will during lectures. It seems to be a good addition to the on board stereo mic of the recorder.

I got interested in building one after I saw this home built mic:

Only problem was, he didn't say how the wiring went. Well, now I know.
