This kit will allow you to modify your home mini to allow line in for external microphone, and line out for speaker.

Some soldering skill required.

About Line level signals.

See this link for a good explanation:

This kit expects a line level input signal. This is ideal for transmitting over long distances, so a 10m cable is not a problem. 

The signal should be, ideally, 3 volts peak to peak for maximum audio quality.

This includes signal from your laptop, smartphone, mp3 player or a line out source.

Do not connect a higher level signal or you could destroy the input circuit.

If your application requires connecting an external microphone to the line in signal, you must ensure that you are using a microphone pre-amp that will boost the signal to this level.

Out of the box headset microphones will perform poorly without proper signal amplification.

I have orders some MAX9814 electret mic with pre-amp units which feature auto-gain control to keep the microphone signal at the right levels. I will try them out with the mod kit and have them for sale here if they perform well.
