Not to be cynical, but I have always found that the parts specified for
magazine articles are virtually unobtainable, but the author has a supply of
them so that they can sell you a kit.

If I have anything to do with a magazine article, I end up studying it and
then making up my own design (my I/R Controlled Robot is a good case in
point - it literally took me 6 months to get a working prototype from the
April 1996 Electronics Now article).

Good Luck!

Today, the commercial sector is advancing computer and communication
technology at a breakneck pace.  In 1992, optical fiber was being installed
within the continental U.S. at rates approaching the speed of sound (if
computed as total miles of fiber divided by the number of seconds in the year).
