About RF Cafe
Copyright: 1996 - 2024 BSEE - KB3UON 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...

Crop Circles by NVIDIA |
 Aliens
sculpt crop circles with regularity on the country sides of England,
so the appearance of this 310-foot pattern carved into a barley field
in California left the locals wondering if ET and his gang were broadening
their "hood" by tagging spots in the U.S. As it turns out, the spectacle
of
agricultural art was the handiwork of the NVIDIA company, done as
a promotional scheme to draw (cut, actually) attention to their newest über
video microprocessor chip. Sporting 192 processor cores, the
Tegra K1 claims, "the chip would make for a tablet more powerful
than an Xbox 360 or PlayStation 3 game console, while consuming one-twentieth
the power." Those little depressions in the center of the IC are the
Braille form of the number 192. GPS-equipped tractors are able to create
patterns with amazing accuracy, but in this case the pattern was laid
out and cut by hand. Clever, non?
