RF Cafe: 24-hour animation of global commercial air trafficHere is very cool animation of global commercial airline traffic over a 24-hour period. Watch the distinct patterns form and dissipate as the day/night terminator moves across the face of the Earth.

RF Cafe: Garae door openers not workingMysteriously, almost all the garage door openers in one neighborhood stopped working around Christmas Eve. The hard-wired wall switches work, and some remote controllers work when inside the garage, but not outside. People are blaming the nearby military base, but the Fed says no way. I suspect someone attempted a hijacking of the openers' codes. It is doubtful that a single RF interferer could affect so many systems without being obvious in other ways. Do you have a theory?

10.68 Megajoule Electromagnetic RailgunThe Navy recently set a new world record for the most powerful electromagnetic railgun ever fired. The gun fired an aluminum projectile at 10.68 megajoules, traveling at 2,500 meters per second (Mach 7). Eventually, the Navy wants to produce a 64 MJ version with a 200 nautical mile range that will fire 3,000 rounds per gun barrel. This will keep dangerous gunpowder loads off the ship.

RF Cafe Cool Video: Animaris Currens VentosaAnimaris Currens Ventosa. That is a new "species" as dubbed by it progenitor, Theo Jansen. Theo's massive creations are amazingly sophisticated mechanical contraptions "created" to roam open beaches throughout their natural lives. His "bone yard" is full of "extinct" models that have succumbed to natural selection due to an imperfect creator. Here is the webcam inside his workshop.

RF Cafe: IEEE-USA Online Video Scholarship Competition 2008-2009Find out how to enter the IEEE-USA's online video scholarship competition for engineering undergraduates. Titled "How Engineers Make a World of Difference," this effort is designed to inspire junior high school students to prepare for an engineering career. Total of $5,000 in prizes available (it was $10k last year). Entries due by 16 January 2009. Here is last year's winner.

RF Cafe Cool Pic - Magnetic levitation light bulbWireless energy transfer is getting a lot of press these days, with the ultimate goal being not just wireless but also battery-less devices. To illustrate the concept, Robin Massink, from the Netherlands, has built this magnetic levitation light bulb - very cool.

RF Cafe Cool Video: Aiko... "When Science Meets Beauty"Taking another step closer to true humanoid robots, Canadian Trung Le, has introduced Aiko to the world. His extensive background in software and robotics led to developing Biometric Robot Artificial Intelligence Neural System (aka B.R.A.I.N.S.) software to control Aiko. She can read, recognize objects, respond to touch, and perform physical tasks.  Some have dubbed Aiko "She-3PO."

RF Cafe: Precision Approach Radar DisplayThis 1959 video shows a precision approach radar system (FPN-16) that was part of the one I worked on in the USAF. It is shown sitting on a turntable at Craig AFB, Selma, AL. Here is a photo I took of the PAR display on one of our radar shop's MPN-14, ASR-PAR mobile radars, circa 1981. Hi Don!

RF Cafe: Click to view film on the operation of modern appliancesThe opening frame here displays, "In this film we shall study scientific principles involved in the operation of common home electrical appliances." See what the 1940s "modern home" looked like - it would be considered lower class today. Thankfully, gone are the bad old days of no safety grounds and no double insulated plastic cases (recall that plastic did not come into widespread use until the 1950s).

RF Cafe Cool Video - The Hoover DamSometimes while buried all day in a lab, peering through a microscope to laser trim a power amplifier tuning circuit or to solder down an 0201 resistor, it is easy to forget about the macro scale projects at the other end of the electrical / electronics spectrum. This IEEE.TV tour of the Hoover Dam covers a bit of history and the inner workings. Be sure to visit the official Hoover Dam site and look at the old construction photos. It is pretty dam[n] inspiring.

RF Cafe Cool Video: Murata Cycling RobotI've said it before, but I'll say it again: Japanese advances in humanoid robots has been absolutely amazing and unparalleled. This miniature "Murata Boy" incorporates multiple sensors for achieving balance, navigation, and obstacle avoidance skills. Its technology has applications in real-world vehicle stabilization and navigation roles, and for handicap assistance. The video is a bit slow moving (made at the Electronica 2008 show), but it is worth watching the entire show just to see what this little dude can do.
