<DIV><FONT face=Arial size=2>The mics are called "electret" : you need a
resistor (around 1K to 3.3K) from the + side of the mic to a positive voltage
(usually 6V). Then, the audio is take from that connection *through* a 1uf,
non-polarized capacitor.</FONT></DIV>

Elements... am I just stupid?</DIV>

FAMILY="SANSSERIF" PTSIZE="10">So today I made a Radioshack run and picked up
a bunch of components - diodes, pots, rectifier, and.. 3 microphone
elements. But I seem to be lacking in something. I attached the
red lead to the contact on the side of a 1/4" audio jack and the white lead to
the contact on the bottom, put a cable between that and a tape recorder with
1/4 input, and recorded... got nothing save a few clicks when my fingers
shorted the thing by accident. Switched the polarity, same
results. Tried the other 3 mics, same results. Then I tried each
into a piece o crap guitar amp (about 3 watts, iirc) and got nothing but
shorts again. Am I missing something terribly obvious, or did I pick
three bad elements out of the five they had?</FONT>
