Turns out this sensor needs a little more than an amp to be useful.
Feedback systems, calibration, linearizion, and appropriate 
displays are all needed.  While none of this is show stopping 
to anyone in electronics, getting all the design requirements 
written down took some research time.

That is getting to be the case.  But a couple years ago the 
off-the-shelf stuff had kilobuck price tags, whereas last year 
you could put together something yourself for a few dozen dollars.
