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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

My Hobby Website:
This collection of video and a few audio files represents files that have been featured on the RF Cafe homepage. Every week or so a new file is added that should be of interest to RF Cafe visitors.
Please send me an e-mail if you have a good subject. Note: "Videos for Engineers" formerly went by the name "Cool Videos."
Dr. Flury, of the ESA, has created this animation showing
the accumulation of functional satellites and space debris over the 1957 (Sputnik 1) to 2000 time period.
Stats on the breakdown of types of debris are on the website. E-mail collision warnings are issued daily.
"The Great Global Warming Swindle," produced
by Britain's WAGtv. The documentary is broken into
9 parts. This is the part of the story not publicized by the $£€Billion industry that thrives on it.
Watch it... if you dare.
Japan's Aerospace Exploration
Agency (JAXA) has finally released the
video of astronaut Takao Doi's famous boomerang toss in space. Q: Will it work outside the ISS?
Watch a new 3G iPhone get pulverized into dust
in Blendtec's latest "Will It Blend?" video series.
This is an ingenious marketing scheme by Blendtec, where the begoggled scientist, in a laboratory environment,
determines whether various high-tech devices will "blend."
While not quite as high on the innovation scale as Scotty's
this "metal rubber" is pretty close. It can be heated, frozen, washed or doused with jet fuel, and still
retain its electricity-conducting properties.
Compliments of Professor Poliakof at the University
of Nottingham, The Periodic Table of
Videos is a complete set of short videos for 118 elements. "In the space of a few hours
I lectured to more people than I had in my entire life." It's like a Monty Python version of the Periodic
This is the world's first full-sized Babbage
Difference Engine #2; Babbage completed the plans in 1849, but never built the machine. Composed of
8,000 parts made from five-ton bronze, steel and cast iron, this magnificent 5-ton machine calculates
results to 31 significant digits. A manually cranked handle powers the gears, cogs, cams, and wheels.
This demo video
of the Airborne Laser (ABL) is phenomenal. A high-energy, 1.315 micron wavelength laser designed
and built by Northrop Grumman, is installed in a Boeing 747-400F. The test phase will culminate in an
airborne intercept test against a ballistic missile in 2009.
This is event of a lifetime for some in
our trade. The world's top circuit assemblers descend upon New York City to demonstrate their
agility, speed, and prowess in the Olympics of their trade: The NYC Soldering Championships. Frank Duncan,
aka "Spec," emerges as the new king of the soldering iron. The video did not mention whether steroid
tests were given, or if lead-free solder was mandated.
Need a vacation to calm the nerves?
Well, traveling the El Caminito
del Rey ("The King's Walkway") probably is not for you. The now dilapidated walkway was built in
1901-1905 along the steep walls of a narrow gorge in El Chorro, Spain. Maybe it is just what you need,
though, make obstacles at work seem insignificant. I'll bet
Bob Pease has walked this trail,
and he is in his 60s.
