December 14, 2014

Visit the Crossword Express website - RF CafeTake 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.

Wright Flyer "Kitty Hawk" - 1/24 scale model - RF Cafe111 years ago this week (December 17, 1903), Orville and Wilbur Wright made their historic first flight whereby a human and aircraft took off and flew under its own power. The Wright Flyer, piloted by Orville, took off from rails on a dune at Kill Devil Hills, NC, and remained airborne for 120 feet before landing on the beach below. The location was chosen for the orographic lift generated by the ocean winds blowing up the sandy slopes. This week's crossword commemorates the event by incorporating many relevant terms and clues. Enjoy!

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
