Build a Microphone plug
Unfortunately, the Zaurus doesn't have a microphone built-in.
But you can build a very small microphone plug which fits into the earphone
connector in the top right corner of the Zaurus. You only need a 3.5 mm plug
(mono) and a very small microphone which is soldered directly onto the contacts
of the plug and fits in its housing.
The parts can be ordered
from Conrad Electronics in Germany, or from
us either as a kit or ready-to-use.
