RF Cafe Videos for Engineers - Mythbusters on RFIDJust how secure (or not secure) is RFID? Listen to Mythbusters' Adam Savage's tale of what happened when they decided to do a story on RFID, and why, so says he, there never will be an RFID episode. It is a good example of how financial sponsors influence what information will or will not be presented to the public. There were 210 comments on the video when this was posted.

RF Cafe Cool Product - Butane-Powered RechargerBoasting 6x more efficiency than using a wall charger, a 5-10x improvement in volumetric energy density, and a 20-40x improvement in gravimetric energy density compared to a Li-Ion battery, Lilliputian Systems says its butane-powered mobile device charger is a clear choice for users tired of battery power running out in the middle of a meeting or flight. Approved for use on airlines, these units should be available early next year.

RF Cafe Cool Pic - Remote Controlled BeetleThis project sponsored by DARPA gives a whole new meaning to the electronic surveillance "bug." In this case it uses a real bug. A wireless controller stimulates the giant flower beetle's optical and muscle signaling system to command takeoff, landing and left / right turns. The only power needed is a small battery for the controller, and a little pollen. Heat sensors, microphones, and cameras will eventually be added.

RF Cafe Visits Beantown

On Tuesday, June 9, Melanie and I spent an enjoyable, albeit very busy, day in Beantown, at the Boston Convention & Exhibition Center. This was the fifth time in the history of the International Microwave Symposium (IMS) that Boston hosted the event. Being a big fan of M*A*S*H, I cannot think of Boston without also thinking of Major Charles Emerson Winchester, III.

RF Cafe: IMS 2009IMS 2009 was a huge success from the standpoint of RF Cafe. My purpose was to spend a full day making contacts with as many of my advertisers as possible. Perhaps unbelievably, I have only ever met a handful of the many advertisers who have invested their promotional budgets in RF Cafe. They are the people that help to deliver the vast resources of RF Cafe to you, and who, for the last two years, have provided for my full-time income. Fortunately, my objective of meeting everyone was achieved, and I got many... (more)
