RF Cafe Engineering Crossword Puzzle w/Weekly Headlines
October 8, 2017

For the sake of avid cruciverbalists amongst us, each week I create a new engineering and technology themed crossword puzzle, mathematics, chemistry, physics, and other technical words. At least 10 clues in this puzzle with an asterisk (*) are pulled from this past week's (10/2 - 10/6) "Tech Industry Headlines" column on the RF Cafe homepage (see the Headline Archives page for help). Enjoy!
