A unique treatise on Nikola Tesla's life - RF CafeNikola Tesla - The Forgotten Wizard. This is a unique, 10-minute treatise on the political and personal battles Nikola Tesla fought in his lifetime. It brings out some some of his ideas that I had never heard of.


Fire from salt water - RF CafeFire from salt water? Erie, PA, radio technician John Kanzius serendipitously discovered that his radio frequency generator could release the oxygen and hydrogen from saltwater and create an incredibly intense flame. His finding came as a result of experiments he was performing for a revolutionary cancer treatment that nonintrusively zaps cancer cell with RF energy.


IEEE's Video Contest winners from Louisiana Tech University - RF CafeIEEE-USA held an Online Engineering Video Scholarship Competition for Undergraduates, with $6,000 in scholarship awards. Here is the #1 winning video from two dudes at Louisiana Tech University - it is pretty good.


Falkirk Wheel - RF CafeThe Falkirk Wheel (U.K.) is a one-of-a-kind canal lock implementation that uses a balanced, rotating arm to simultaneously raise and lower vessels travelling in opposite directions in the canal. 15,000 bolts were matched with 45,000 bolt holes, and each bolt was hand tightened due to stress factors.


EE Time's Web TV Teardown of an HP-35 Calculator - RF CafeEE Time's 'Teardown TV' performs a RF Cafe: HP35 (1972) next to an HP35s (2007)teardown of an HP35s Calculator. This is a resurrection of the engineering school stalwart of the 1970s and 1980s, the HP35.


U.S. Navy's USS Lake Erie scores a direct hit on the crippled satellite - RF CafeIt's a Hit!
An SM-3 missile was fired from the USS Lake Erie in the Pacific at about 7:26 PST and collided with the crippled satellite about 130 miles above the ocean, travelling at 17,000 mph. We have intercepted and destroyed an ICBM equivalent object as it entered the upper atmosphere - on the first shot! ...and some thought the Strategic Defense Initiative (Star Wars) concept would never be realized.

GFS Projects Limited Unmanned Aerial vehicle (UAV) GFS13A - RF CafeThe GFS Projects Limited Unmanned Aerial vehicle (UAV) GFS13A is able to take off and land vertically; it can hover at heights up to eighty feet. The GFS UAV uses the Coanda principle to create lift, it has very little downwash and is aerodynamically stable.


Wireless transfer of energy - RF CafeIt's all the rage lately - wireless transfer of energy. Like most new technology concepts, the idea is great, but practical implementation is the challenge. Magazine articles have heralded it as The Next Big Thing for powering everything in your house and office - finally eliminating cords and batteries the same way cordless phones and wireless modems eliminated cables. In this case, going from the lab to the marketplace will take redefining physics, or glow-in-the-dark houses spewing kW of power to get a AA battery's worth of power to an electric razor.


Purdue Society of Professional Engineers earned the top spot in the 21st annual national Rube Goldberg Machine Contest at the Purdue Armory - RF CafeThe Purdue Society of Professional Engineers team took 1st place in the 2008 national Rube Goldberg Contest. The task for this year? - A Hamburger Making Machine. The contraptions needed to assemble a hamburger consisting of no less than one precooked meat patty, two vegetables and two condiments, sandwiched between two bun halves. Sponsors included some big names like BAE, Daimler-Chrysler, GE, Lockheed Martin, Omega Engineering, and Rockwell Collins.


"Radio Hams" docudrama from Pete Smith Films - RF CafeThis 1939 docudrama, "Radio Hams, " is a short film produced by Pete Smith for Metro-Goldwyn-Mayer. Jimmy Mulligan uses Ma Mulligan's egg beater to wind coils for his radio set. Listen in on the dramas as they unfold. (Thanks to Cornel for this)


KDP Crystal Growth - RF CafeA synthetic seed crystal is placed in a tank filled with a metric ton of supersaturated potassium dihydrogen phosphate (KDP). As it rotates on a turntable for two months, the square crystal grows to be as large as 800 pounds. It is the used in the National Ignition Facility to process laser beams on their way to the target chamber. Notice the part about measuring the crystal where the guy pulls out a Wal-Mart quality tape rule to measure it.
