help with simple question(s) needed

[Beowulf]

I just built the gaussmeter from plans at
http://my.execpc.com/~rhoadley/magmeter.htm
I am just a newbie, and know little about electronics.
Two questions for anybody that can help me:
(1) Is there any way to increase the sensitivity of the gaussmeter
perhaps by putting two of them in series or something?
(2) Is there any way to build my own gizmo to input this into my
laptop computer serial port? I found a gaussmeter probe that hooks
into a laptop serial port, with basic software to write comma separated
value data values, and even this costs $500. I would like to build my
own such setup if possible to collect magnetic field info in real time.
