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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

November 1963 Popular Electronics

November 1963 Popular Electronics Cover - RF CafeTable of Contents

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

Most of these matches of the devices and its inventor are pretty easy for people who have been around electronics for any length of time (well, not if the length of time is a day or two), but a couple just might stump you. This Electronics Inventors Quiz appeared in a 1963 edition of Popular Electronics, so you won't be challenged with knowing the inventors of the LCD or MEMS devices, but neither will you have to know who came up with the abacus or the Archimedes screw :-).
