"A new method that precisely measures the mysterious
behavior and magnetic properties of electrons flowing across the surface of quantum materials
could open a path to
next-generation electronics. Found at the heart of electronic devices,
silicon-based semiconductors rely on the controlled electrical current responsible for powering
electronics. These semiconductors can only access the electrons' charge for ..."
Printed circuit boards (PCBs), especially high density
and many layered, were still a relatively new technology in 1969. Point-to-point wiring was
still a large part of most products in the commercial, military, industrial, and aerospace
worlds. Producing artwork and contracting for a lot of PCBs was rather expensive, especially
in small quantities. Many people, including me, made quite a few single- and two-sided boards
using photoresist pens and self-adhesive tape and pads, then bathing them in an etchant solution
of ferric chloride. Through holes were made on a drill press and then traces and pads were
tinned with flux and solder ...
"At a time when much of the industry's attention has
been on midband spectrum, Nokia is taking it up a notch by pursuing tests in the
90-96 GHz range. The vendor filed an application with the FCC asking for
permission to conduct the tests over the course of two years at Nokia facilities in Murray
Hill, New Jersey; Arlington Heights and Naperville, Illinois; and Sunnyvale, California. The
"TechInsights explored some of the Bluetooth and cellular
IoT devices that it expects will dominate the Internet of Things for some time.
SoCs will be rapidly adopted by consumer IoT devices such as smartwatches and health and
fitness products. Two emerging cellular IoT standards - narrowband IoT (NB-IoT) and Enhanced
Machine-type Communications (eMTC) - will see wide applications in smart meters, bikes and
other new emerging ..."
Accuquartz wristwatch is not the first quartz-controlled wearable timepiece; however,
it was the first to be manufactured in the U.S. Interestingly, it is not a fully electronic
watch because the quartz crystal stimulates a mechanical tuning fork which ultimately drives
the hands. Bulova's first tuning-fork-driven "Accutron" was introduced in 1960. It sported
a 360 Hz tuning fork that was stimulated by a pair of electromagnets ...
Update: "The corporate headquarters of test company
Keysight Technologies is shut down and suffered minor damage in the wildfires
that have wiped out parts of Santa Rosa, California. Although a local news report claimed
that the campus had been destroyed, the most recent update from the company said that as of
Monday afternoon, 'all four main buildings are intact, although there appears to be some minor
damage. Two modular structures and several automobiles suffered more ..."
sensor based on SansEC. NASA Langley Research Center has developed a robust, wireless
temperature sensor that does not require an electrical connection. The temperature sensor
is built on NASA's SansEC sensor platform, which takes advantage of measuring dielectric changes.
The temperature sensor is damage tolerant, wireless, flexible, precise, and inexpensive. One
promising application is for tire temperature ..."

an unprecedented security flaw that allows hackers to snoop on internet traffic, researchers
have revealed. The vulnerability is the first to be found in the modern encryption techniques

There are not too many honest-to-goodness
electronics repair shops around anymore - those where the proprietor uses multimeters,
oscilloscopes, and signal generators to troubleshoot and align equipment. In fact, I would
guess that most such shops do most of their business based on customers who find their services
as the result of a Google search. You can find lots of cool videos of technicians demonstrating
(and showing off) their collection of test equipment and solder rework stations - mostly for
fixing vintage audio and video gear. Nowadays the smartphone screen replacement dude / dudette
working from a kiosk in the shopping mall is considered an electronics ...

"Key to the stochastic-resonance device's constant
buzzing of movement is the use of single-walled carbon nanotubes (SWNTs) in parallel and spanning chromium electrodes, and phosphomolybdic
acid (PMo12) molecules [red and blue clusters]. It seems counterintuitive that background
noise - like a white noise - could actually be used to help detect faint signals. But that's
what happens in an unexpected phenomenon known as stochastic ..."
One article by Danny Rockett introduces an approach
to selecting the most suitable battery for a mobile device. I have posted many of my own commentaries
on the importance of
critical battery selection based mainly on my use of various technologies in my flying
models. Kickstarter and other startup funding websites are full of gizmos people have invented
that are battery-powered, so it is not just the "big boys" who need to be concerned. Back
in the early days of Bluetooth, I jokingly said that I should invest in battery company stocks
because if the scheme took off, I would be rich in a couple decades due to all the wireless
devices. Well, I didn't - but it did - and now I'm still not ...
"Researchers at the Harvard John A. Paulson School
of Engineering and Applied Sciences (SEAS) developed the first on-chip
metamaterial with a refractive index of zero, meaning that the phase of
light could be stretched infinitely long. The metamaterial represented a new method to manipulate
light and was an important step forward for integrated photonic circuits, which use light
rather than electrons to perform a wide variety of functions. Now SEAS researchers have ..."
It has been over a year since I have worked on any old

- restoring and maintaining a bit of world history. If you do a search on the RF Cafe website,
you will find many types of color code charts that were published over the decades by the
likes of Electronics World, Popular Electronics, Radio & TV News, Short Wave Craft ...

"When you're really harried, you probably feel like
your head is brimful of chaos. You're pretty close. Neuroscientists say your brain operates
in a regime termed the 'edge of chaos,' and it's actually a good thing. It's a state that allows
for fast, efficient analog computation of the kind that can solve problems that grow vastly
more difficult as they become bigger in size. The trouble is, if you're trying to replicate
that kind of chaotic computation ..."
Georg Simon Ohm's eponymous "law," i.e.,
Ohm's law, is perhaps the best-known formula in the realm of electricity and electronics.
Although Mr. Ohm did not know it at the time, his conclusion holds up in both the macro
and micro scale worlds of electron behavior. Voltage is equal to the product of a resistance
and the current flowing through it, E = I * R. It is hard to believe that we have only had
his result, announced in 1825, at our disposal for less than 200 years. A thorough grasp of
Ohm's law is a minimum requirement for entry into the fields of electrical and electronics
work; fortunately, only a fundamental grasp of algebra is required. Kirchhoff's law is a relatively
easy next step. The big hurdle comes with wanting ...
