Nick Veasy's X-Ray Art - RF Cafe Cool PicNick Veasey is an x-ray artist. Owner and qualified operator of a shielded bunker full of x-ray equipment, Nick's mission is to, "challenge [the] automatic way that we react to just physical appearance by highlighting the, often surprising, inner beauty." He means it quite literally, the inner beauty part. Using lead-lined floors and walls as backdrops, a huge variety of subjects have been selected for imaging, including television sets and cameras, a rose and an orchid, children's toys, farm animals (none harmed in the process, I assume), a host of nasty insects (all harmed, hopefully), cockles and mussels, boxer shorts (sans human) and a folded shirt, binoculars and vacuum tubes, a French horn, and a Slinky. Subjects have not been limited to those which could fit inside the studio, however. Macro images have been assembled from a collage of many separate images. Vick exposed a bus full of people, a small office building (including elevator), and the pièce de résistance, a jet airliner being serviced inside a hangar. The airplane took more than 500 images. I'm guessing the outdoor images required cooperation with the subjects, especially considering the x-ray exposures involved. Cobalt, iridium, and ionizing radiation can be scary stuff. You might want to check out his book, X-Rays: See Through the World Around You.

RF Technology International Magazine -  RF Cafe Cool ProductThe apparently indefatigable Gary Breed, former editor of RF Design and current founder/editor of High Frequency Electronics, has just launched a new publication: RF Technology International. Subscribers to HFE received the premier edition within the last week or so. Is there really a need for a new publication that caters to the RF/microwave world? Gary believes there is. Per his opening editorial, "The mission of this new multi-media publication is simple - Collect, sort, select and present information that is valuable to engineers who work in RF, microwave and high speed technology." Chief amongst the goals is to provide a historical perspective to new developments; that is, "We Build the Future on a Foundation Established by Earlier Generations." With as rapidly as technology progresses and the pressure to invent and produce increases, there is precious little time to reflect on how we got to where we are today. Some people don't think that is important as long as innovations keep flowing. I do. Some of the most intriguing articles I read - and I read lot - contain references to the people and events that led to the breakthrough technology being reported. The historical, indeed the personal, perspective turns an otherwise dry presentation of words and numbers into a enjoyable story. I look forward to seeing how Gary and his staff deliver on this promise.

Soaring College Tuition Costs - RF Cafe SmorgasbordSkyrocketing costs for college tuition have been an issue for a long time. Reports published lately show how the price of a semester of college has exploded in the last few decades. Those same investigations have determined that a big part of the increase has been due to the ease at which school loans can be obtained - very similar to the way housing costs have increased with easy access to mortgage money. As students were more able to pay the rate, supply and demand allowed costs to go up accordingly. For instance, the above chart shows that from 1982 to 2007 the cost of tuition, fees, room, and board increased by an average of about 450%. During the same period the median family income increased 150% and the CPI was up 100%. Even medical care "only" increased by 250%. To illustrate the oblivion nature of far too many students, at the behest of professors and administrators who are themselves part of "the 1%," from an income and privilege standpoint, the students attend Occupy Wall Street (OWS) demonstrations to rail against the 1%. Ivory Tower pontificators blasting Capitalism while profiting from it are not limited to universities; their names are in the news on a daily basis.

Shperical Flying Machine - RF Cafe Video for EngineersThe Japanese have been way ahead of the curve in the robot world for many years. Combining autonomy with wireless control has led to this "Spherical Flying Machine" that was demonstrated by the Japan Ministry of Defense. Beginning with a dose of theatrical showmanship, the mystery craft jumps out of a round Styrofoam container after the lid is suddenly popped off. What emerges is a very obviously highly stable and maneuverable sphere that effortlessly floats above the stage and audience, while intermittently flitting about like a dragonfly moving along the shoreline from cattail to cattail. Multiple onboard gyroscopes provide attitude control and stability so effective that even after being hit or pushed, it rights itself. Flying is not its only method of locomotion; once on the ground the spherical flying machine becomes the spherical rolling machine. It can also hug a wall near the ceiling and navigate through a building. This allows it to be used for surveillance in almost any environment. Its quite electric motors, most likely powerful, microprocessor-driven brushless models given life by high-C lithium polymer batteries, provided plenty of motivational force. A 2.4 GHz radio control system was used for guidance. Come to think of it,...<more>
