Then there's the story of Hedy Lamar, a Hollywood actress during the 30s and 40s, and often considered the 'world's most beautiful woman'. But there was a brain beneath her lovely hair, and she found refuge from the shallowness of show biz by analyzing and inventing. As World War II began in Europe, she began to wonder why torpedoes could not be equipped with directional devices controlled by radio signals. The reason given was that the radio signal could easily be jammed by the enemy. She began to concentrate on how to make radio signals "un- jammable", and she devised the notion that guidance instructions could be sent to torpedoes in short bursts of data spread over multiple frequencies. Called 'frequency hopping', it would prevent the enemy from interfering with the many different signals.
Lamar got a patent for the concept and then offered it to the U.S. Navy. The mossbacks there scoffed and basically told the 'little lady' to go back to Hollywood and pose for glamour shots. She forgot about it. When her patent expired another patent hound found it and saw its merit. The idea was dusted off and refined and now is the technological basis for Wi-Fi, Bluetooth and GPS. She was finally recognized for her work in 1997, by the Electronics Frontier Foundation. She never made a dime off of it.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
