In your final few minutes of the workweek, try your hand at this "Electronics Helix Puzzle," provided by Mr. James Kimsey in a 1971 issue of Radio-Electronics magazine. It it not as much of a challenge as a classical crossword puzzle, but is still worth attempting. In some ways, though, if you get stuck on a word there is more help available with a standard crossword because there are more than just two (the first and last letter in this case) intersecting letters available to help. If after completing this Electronics Helix Puzzle you would like to try your hand at one of those traditional type crossword puzzles, consider working one (or more) of my weekly RF Cafe engineering and science-themes puzzles.
