Electronics Theme Crossword Puzzle
April 9th, 2023 - Easter Sunday

This custom RF Cafe electronics-themed crossword puzzle for April 9th, Easter Sunday, contains words and clues which pertain exclusively to the subjects of electronics, science, physics, mechanics, engineering, power distribution, astronomy, chemistry, etc. It'll keep you busy while the kids hunt for Easter eggs. 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. Enjoy!
