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...

The Bedol Water Clock

This water-powered clock appeared on the EDN website. Rather than get the story second-hand, I went to the Bedol website. According to the manufacturer: The handsome Bedol Water Clock works 100% on natural power. No batteries, no chemicals, no electricity – no pollution. You don't even need to wind it up! Just fill the tank with natural tap water and you're set for 12 to 14 weeks of accurate timekeeping before refreshing. (You won't even lose time while changing water, thanks to the built-in memory chip!) With its bold modern styling, space-age accuracy, and surprisingly low price, the Bedol Eco-Friendly Water Powered Clock is ideal for home or office – or as a unique gift item. Not bad for $25, and no batteries required. There is a video that explains the process.
