There appears to be 8 reed switches, and two rotating magnets arranged
adjacently.
Perhaps one is not a magnet, and just a counter weight.

I marked one of these magnets and then rotated the vane shaft 45% and took a
reading, and repeated until the marked magnet was back to the original
position. (previous table)

I've just checked though and there are other valuse combinations, and also a
second set of four volt values.
So perhaps there are more than eight recordable positions.

volt.ALL         0.0658604, 0.0600009, 4.55241, 4.5428
volt.A  0.0644541
volt.B  0.0661729
volt.C  4.54171
volt.D  4.54741
volt2.ALL       0.0352349, 0.0302348, 0, 0
volt2.A 0.0351568
volt2.B 0.0298442
volt2.C 0
volt2.D 0

More research needed...

Vey interesting. I'm surprised directions 5-8 don't have two channels with
non-saturated values. (A between position.)

Well, I opened it up and had a look, the 8 directions each with 4 volt
readings, translates to the following table.

        1       2       3       4       5       6       7       8
A       *0      4.5     4.5     4.5     *2.3    4.5     4.5     4.5
B       4.5     *0      4.5     4.5     4.5     *2.3    4.5     4.5
C       4.5     4.5     *0      4.5     4.5     4.5     *2.3    4.5
D       4.5     4.5     4.5     *0      4.5     4.5     4.5     *2.3

I notice much talk of RRD, and it does look interesting, but I was thinking
I would keep my data for many years and writing the graph code is part of
the challenge for me.

Mysql would be my db of choice, but the interpolation features of RRD look
intriguing.

I think I may use this project as an opportunity to play with python, I hear
nothing but praise for this language.
