Yesss! I've won the obscure connection award
>> A cat's-whisker detector (sometimes called a crystal detector) is an antique electronic component consisting of a thin wire that lightly touches a crystal of semiconducting mineral (usually galena) to make a crude point-contact rectifier. Developed by early radio researchers Henry H. C. Dunwoody, G. W. Pickard and others, this device was used as the detector in early crystal radios, from the early twentieth century through World War II, and gave this type of radio receiver its name. Crystal radios were the most popular type of radio until the mid 1920s. The cat's whisker detector was the first type of semiconductor diode, and in fact, the first semiconductor electronic device. Cat's whisker detectors are obsolete and are now only used in antique or antique-reproduction radios, and for educational purposes. -- Wiki<<

I saw the part about galena being a mineral but didn't dig any deeper... you are a PITA!!!!!!

OK, somebody's gonna have to essplain how you get from "galena" to "beard"....![]()

Since nobody but the poster finds "galena" relevant, I went back to the prior post of whiskers. Whiskers equals beard. Hugs.
