Electronics Theme Crossword Puzzle
October
8th, 2023
|
|
This custom RF Cafe electronics-themed crossword puzzle for October 8th
contains only clues and terms associated with engineering, science, physical,
astronomy, mathematics, chemistry, etc., which I have built up over more than
two decades. 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!
