Edmund Brown created a
handful of these "R-E Crossword Puzzler" challenges for Radio-Electronics
magazine. They are akin to crossword puzzles, except that all the clues and
words are Across (no Down). Each row shares a letter with the adjacent row, so
all but the top and bottom rows share two letters, which are provided by Mr.
Brown. These are pretty easy, but occasionally the inclusion of a somewhat
outdated word makes it a bit more difficult. You will probably be able to whip
right through this one; there is only one word that might cause some head
scratching if you are not a regular reader of RF Cafe articles.
R-E Puzzler
 by Edmund A. Braun
Try this "only-across-word" puzzle based on electronic terminology. Each word
is connected to the one above and below by a single letter. It should be fairly
easy to get a perfect score except perhaps for someone who thinks "Heaviside layer"
is the problem of the obese, or that "microhms" are similar to bacteria! Got a pencil?
Ready? GO!

 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.

Cruciverbalist:
A cruciverbalist is a person who is skilled at creating or solving crossword
puzzles. The term is a combination of "cruci-" from "crucifix," meaning cross, and
"verbalist" from "verbal," indicating a person who deals with words.
cruciverbalists are often responsible for designing
crossword puzzles, and they possess a deep knowledge of wordplay, vocabulary, and
the techniques used in constructing and solving crosswords. They aim to make puzzles
that are both challenging and enjoyable for crossword enthusiasts.
