DIY "bullet" style harmonica mic!

Step 4 Wiring and screwing.

Now you gotta bust out the soldering iron and wire up the guts. The hot lead from the mic element gets connected to pin 3 of the potentiometer. The hot lead of the 1/4" jack gets connected to pin 2 of the potentiometer. Both the ground lead of the mic AND of the 1/4" jack get connected to pin 1 of the potentiometer. Leave the connecting wires long enough to give you a bit of play around room, but not too long that there will be a birds nest in the completed mic. See the pic for a guide, as well as the schematic.

Once you've got them wired, you attach the potentiometer and the 1/4" jack to the metal fence post cap through the holes you drilled. Make sure you wrap the terminal part of the potentiometer with electrical tape, otherwise you'll probably end up shorting the signal leads to the metal chassis, and all you'll hear when you plug it in will be a buzzing sound. Watch the last part of this video to see how to do that:

(PS. Don;t get confused when you see a different mic element in the video from what I'm showing in the pictures. I originally used a different microphone element in this mic, which did not need to be gasketed the way were are doing it here. That was a very cheap element from a crappy karaoke mic. The audio technica one I'm showing you how to put in in this instructable is MUCH better.)
