technology themed crossword puzzle. All the words are pulled from a hand-built list of terms, names,

with names of movie stars and obscure countries, try the local newspaper. If you want to exercise your
nerd knowledge, this is the one for you.

 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.
