[sdiy] Mag sensor as a CV source

[Tim Ressel]

Toby -- 

My boss has a gizmo on his desk that demonstrates chaotic behavior. Its a
pendulum with a magnet on the end, and several magnets on a plate below. By
changing the position and polarity of the magnets on the plate, one can make the
pendulum move in strange ways. Now couple that with your idea, might me nice!

> The 3517 uses a single 5V supply and the sensitivity is 5 mV/G (gauss). 
> Package is a 3-pin "ultra-mini-SIP". 
> Output with no mag field is about 1/2 supply voltage. Full scale is rail-rail.
> Specs say it will source about 1 mA and sink 10 mA.
