re: designs to make a digitizer sensor
On the other hand, rather than building a new device, one could
use something like the $130 "Signal Lite" which I found on page 2130
(PN#06499479 ) of the 2000/2001 MSC Supply Company Big Book.
It proclaims to be a 3 dimensional sensor, looking like perhaps 1/4 the
length of a thick felt pen, with a precision ground RC 60 0.4000 inch
(+/- .0001") probe diameter, a repeatability of +/- 0.0005",
and has XY overtravel of 0.1" and a Z overtravel of 0.2"
It takes 4 EverReady A76 batteries, and (I suppose) lights up
the LED when the probe is moved. For our application, we'd
stick a photosensor over it (or perhaps take it apart and wire it up).
I don't know the manufacturer, and couldn't find "Signal Lite"
on the Web, so I guess someone should buy one and let the rest
of us know how well it works!
