It really works very nicely.  I discovered some things, (I think), that =
I wouldn't have seen.  First was that I didn't see the "noise" I was =
expecting.  I just don't know about that yet, but it may be some sort of =
programming error or an error in how I am reading the AD.

The most important thing, though, was with my new scope I could see that =
it was wonderfully sensitive to great distances and that it wasn't =
fooled by turning on lights in the room.  (I also could see it was =
picking up the back of my chair, even though it looked completely out of =
the way of the LED reflection.)

I *think* this is telling me that I can greatly increase the sensitivity =
by boosting the signal through an op-amp before going into the AD, with =
a pot to adjust the gain for tuning.
