Add Microphone

To match the tie, paint your microphone amplifier with a little black nail polish.
Cut a piece of ribbon cable longer than the main part of the tie.
Peel off three wires to use with the microphone amplifier, which will live at the knot of the tie.

Insert the ribbon cable up through the inside of the tie. Cut a small hole with a seam ripper inside the knot of the tie and bring the ribbon cable through it.
Strip the ends of the wires and solder them up to the three holes on the microphone amplifier.

Use plain thread to anchor the mic to the tie knot using the large mounting holes.
Back at the Flora end of the board, solder the corresponding wires to 3.3V, GND, and D9.
