A Backwards Extension
of Moore's Law

source: (Intel)
RF Cafe Smorgasbord - Computing power vs. electrical power following Moore's Law pathAssuming the data used is accurate, this chart indicates that Moore's Law describing (not governing) IC evolution, when applied to computing efficiency, reaches back to the first digital computer - ENIAC. A study titled, "Assessing Trends in the Electrical Efficiency of Computation Over Time" found that when computing power as a function of electrical power usage is plotted, it doubles approximately every 18 months. Engineers expect the trend to continue. If the chart had resembled a hockey stick, I would have dismissed it as junk science.

RF Cafe: 50-year anniversary of the laserIt was 50 years ago that the first laser was demonstrated at Bell Labs. Here is a brief photo history of the development, beginning with masers and ending with semiconductor lasers. Low-cost, high efficiency red, green, and blue semi lasers are highly desired by display makers for high definition large screen TVs. Red came first by using GaAs compounds and then blue by using GaN. Green has been not so easy. Achieving the holy grail of 520 nm, where true "green" begins, was achieved just last year - hard to believe, huh? Read all about it in IEEE's Spectrum.

RF Cafe Cool Product - ISEE has developed a compact, low-cost, robust 24 GHz radar sensor (ISM Band included) for automotive, industrial or home applications. Consisting of a planar antenna, a 24 GHz front-end and an OMAP3530 processor unit for signal processing, it measures distances (25 m ±20 mm typical), velocity or properties of objects with RF Cafe Cool Product - ISEE 24 GHz Radar Antenna Radiation Patternhigh accuracy. The system uses a linear FM CW signal. Lunar Lander X-Prize contestants were all begging for something like this a couple years ago (I know because I received many e-mails looking for such a product). Price is only 145€ ($200).

RF Cafe Videos for Engineers - OK Go, This Too Shall Pass Rube Goldberg VideoI have to admit to never having heard of this band, OK Go. They and a cast of many created a pretty amazing, giant size Rube Goldberg machine.
One of my favorite parts is the bowling ball being launched across a fairly large distance and hitting its target to continue the machine's repertoire of imaginative gizmos. The video is nearly 4 minutes long.
