I just looked through my pictures and I was surprised to find that I don't
have any that show the sensor. I will snap a few close-ups tonight...
I also like the idea of doing a more formal write-up with pictures,
schematics, and part sources. It shouldn't be a major project at all.
Before I forget to mention this, I got a private e-mail from John Barnes
today in which he reminded me that it is a good idea to wire a 100-ohm
resistor in series with the reed switch to prevent excessive current drain
and also possible damage to the reed switch if it is accidentally connected
to a motor output.
I'll be sure to include this info in my formal write-up.
