This custom RF Cafe electronics-themed crossword puzzle for January 14th contains
only clues and terms associated with engineering, science, physical, astronomy,
mathematics, chemistry, etc., which I have built up over more than two decades.
Being the 14th day, words containing the letter "N" are marked with an asterisk
(*). Many new words and company names have been added that had not even been added
to the world's technical lexicon when I started in the year 2002. As always, this
crossword contains no names of politicians, mountain ranges, exotic foods or plants,
movie stars, or anything of the sort unless it/he/she is related to this puzzle's
technology theme. You might, however, encounter the name of a movie star like
Hedy Lamarr or a
geographical location like
Tunguska, Russia, for reasons which, if you don't already know, might surprise
you. The technically inclined cruciverbalists
amongst us will appreciate the effort. A full list of all RF Cafe crosswords is
at the page bottom. Enjoy!

 Take a well-deserved break and try your hand at some of these goodies.
Every word in the RF Cafe crossword puzzles is specifically related to engineering,
mathematics, and science. There are no generic backfill words like many other puzzles
give you, so you'll never see a clue asking for the name of a movie star or a mountain
on the Russia-China border.
All of these crossword puzzles were created using the fabulous
Crossword Express (now called "Magnum Opus") software.
