These images have been chosen for their uniqueness. Subject matter ranges from historic events, to really cool phenomena in science and engineering, to relevant place, to ingenious contraptions, to interesting products (which now has its own dedicated Featured Product category).

RF Cafe: Nanotube artIt appears that the new equivalent of "chip art" (aka "silicon art") is "nano art." The notoriously playful science nerd coterie has picked up the gauntlet with their imaginative creations. This particular image is a composite of many nanoartists. Flowers and warts are popular topics, but an occasional lamp shade debuts. Come one guys (and girls)... give us Dilbert, Einstein, or at '57 Chevy.

RF Cafe: Remote controlled beetleMaybe the tinfoil hat wearing types that have been reporting sightings of bug-like mechanical surveillance drones hovering over public events in D.C. are not as nutty as we think. Here is a DARPA-funded cyborg beetle sporting a wireless command/control module that has six electrodes implanted into its optic lobes and flight muscles. Flight commands are sent to the beetle via a transmitter controlled by a nearby laptop. Oscillating electrical pulses delivered to the beetle's optic lobes trigger takeoff, while a single short pulse ceases flight. Signals sent to the left or right flight muscles make it turn.

RF Cafe: IC EvolutionThis series of animated images shows the evolution of integrated circuits. It begins with Jack Kilby's invention at Texas Instruments, then progresses through Fairchild's RTL IC, the first Pentium processor, and finally Intel's Core i7 screamer.

RF Cafe Cool Pic: Camera in the eye socketYeah, it is kind of gross... but kind of cool, too. Prosthetic eyeball user and filmmaker Rob Spence says, "If you lose your eye and have a hole in your head, then why not stick a camera in there?" He calls himself "the eyeborg guy." The camera will have a wireless link to a laptop computer or other receiver/storage device. BTW, he lost his eye at age 13 when shooting at a cow pie.

RF Cafe Cool Pic: Mazda piIntroducing the Mazda π. If this is a marketing attempt to imply the precision to which the car is designed and built, I find it irrational. Yeah, the image is probably Photoshopped, but I wouldn't put it past some clever soul to actually buy and install the numbers. I checked, and the 28 digits used are accurate

(3.141592653589793238462643383). Here are the first 1 million digits of π.

RF Cafe: World's smallest lettersStanford University just raised... er... lowered the bar in the competition to create the world's smallest letters. They have created letters approximately 15 nm tall, using a device known as a scanning tunneling microscope (STM) to push individual carbon monoxide molecules onto a copper surface. Lawyers will love this ability to added even smaller print to contracts. Someone tell the brainiacs at IBM that the gauntlet has been thrown down again.

RF Cafe: IBM 350 Magnetic Data StorageNeed a portable hard drive for your computer? In 1952, it would have looked like this IBM 350 magnetic disk storage unit. It was a marvel of the day with its mammoth 4MB of storage capacity. Disks rotated at 1,200 rpm (today's run at 5,400 or 7,200 rpm). Seek time averaged about 600 ms (typical for today about 15 ms).

RF Cafe: Electronics LampTheron Colucci calls himself "The Electric Light Artist." Theron started in electronics as a Navy technician. He had not considered himself an artist until a few years ago, when he stumbled upon a solder stencil discarded in a trashcan outside a manufacturing facility. Theron held it up to the sun, and, literally and figuratively, "a light went on." Now, he creates high tech expressions of light using recycled stencils. See more examples on his website.

RF Cafe: Melanie with PiAlas, poor Melanie has been around me for too long. We got a new cat from the Humane Society shelter on Saturday. I mentioned that a science type name would be cool. After tossing around a name for her, Melanie came up with Pi (π). Why Pi? Saturday was March 14, aka Pi Day (3.14).

RF Cafe: NASA's Space Power Facility's Vacuum ChamberRemember the Bell jar vacuum chamber you used in chemistry lab for watching water boil at room temperature? That was child's play. NASA, famous for doing things in a big way, has the world's largest vacuum chamber. It measures 100 feet in diameter and is 122 feet tall. I did the math; it works out to about 825 thousand cubic feet. The chamber is used to test satellites and vehicles in space-like conditions.

RF Cafe: Circuit Board CarTalk about taking your work home with you! This Nerd Herd wannabe attached printed circuit boards all over the outside of his car (he probably would have used an AMC Gremlin had one been available). Don't be fooled by the green color, though. I'm guessing the boards are loaded with toxic lead solder, and the weight surely negatively impacts the MPG of the car. Still, it's cool.

RF Cafe Cool Pic: Milled Wood Smith Chart coasterThis milled wood, Smith Chart coaster was sent to me by website visitor Enrique R, of Norcross, GA. The coaster now resides on my Smith Chart Artwork webpage. If you know of any other examples of Smith Chart art, please let me know.

RF Cafe: Amateur suborbital balloon photosSpanish teenagers recently lashed an $82 (60) digital camera to a helium balloon and lofted it to an altitude of 30 km. RF Cafe: Amateur suborbital balloon photosHomemade electronics allowed it to be tracked via Google Earth. Following balloon deflation, the recovery system brought the package to a safe landing 10 km away. This puts the old Estes CamRoc photos to shame.

RF Cafe: Altech buildingWhile verifying hyperlinks on the vendor pages, I ran across this photo Altech's building and thought it looked a lot like a ceramic DIP package on a PCB. It makes a good Cool Pic subject. RF Cafe: Ceramic DIP package on PCB (composite)My image is a composite, the Altech image is real.

RF Cafe: Lard-buttThe object to the left will never fit on the object to the right. RF Cafe: Pico ToiletThen again, neither will mine, and it is nowhere as large as the object on the left. The object on the right is a pico-scale toilet (loo, WC, toilette(s,t), 厕所, inodoro, トイレ, záchod, المرحاض, toalety, शौचालय, casa de banho, or whatever you call it. This nanometer wide (peeco scale?) John is shown at 15,000x magnification.

RF Cafe: World's smallest nanoweldsHere is the world's smallest welding job. "We report that individual metallic nanowires and nanoobjects can be assembled and welded together into complex nanostructures and conductive circuits by a new nanoscale electrical welding technique using nanovolumes of metal solder."
