"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 ..."
"Researchers have modeled the actions of electrons
extreme temperatures and densities, such as those found within planets
and stars. The work could provide insights into the behavior of matter in fusion experiments,
which may one day lead to a sought-after source of clean energy. Electrons are an elementary
component of our world and determine many of the properties of solids and liquids ..."
Did you know that General Electric introduced the first
silicon-controlled rectifier (SCR) for commercial use? It was in 1957. The SCR was one
of the first really high power devices in the semiconductor industry, not for its voltage
and power gain, but for its ability to switch very large currents on and off while having
a relatively low "on" voltage drop. This article gets into the basic theory, operation, and
application of the SCR. The S-band airport surveillance radar that I worked on in the USAF
originally used a vacuum tube thyratron to trigger the magnetron's pulse forming network,
but that tube was replaced with a solid state SCR circuit that plugged directly ...
"After the destruction inflicted across the Caribbean
by hurricanes Harvey, Irma, and Maria, renewable energy advocates are calling for a rethink
of the region's devastated power systems. Rather than simply rebuilding grids that delivered
mostly diesel generation via damage-prone overhead power lines, renewables advocates argue
that the island grids should leapfrog into the future by interconnecting hundreds or thousands
solar microgrids ..."
"I don't know the last time you purchased some new coax,
but it's sold by the foot and can cost an arm and a leg!" - H. Ward Silver, QST
magazine, October 2017,
Hands-on- Radio (p71).
Deciding which fuse to use as a replacement for a blown
fuse is usually a simple matter - read the part number or electrical parameters (current,
voltage) off the package and make sure of its type (fast or slow blow). Of course whenever
a fuse blows, you usually have more or a problem than just a bad fuse. Deciding which
fuse to use when designing a circuit which requires overcurrent protection requires a
lot more consideration. This article from fuse making company Bussmann's Charles James gives
a brief introduction to the kinds of parameters you need to factor into a selection. There's
more to it in most cases - especially ...
"Qualcomm was granted FCC authorization to conduct
experiments using a small 5G R&D development and demonstration network at
4.4-4.94 GHz in its hometown of San Diego. Specifically, the location
is within a 0.5-mile radius of Qualcomm's campus in the Sorrento Valley area of San Diego.
The authorization is effective until October 1, 2019. The application lists 30 mobile units
and four base stations to be used in a test network that will use a single TDD 100 MHz channel ..."

"Every Wi-Fi connection is potentially vulnerable to
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
that have been used to secure Wi-Fi networks for the last 14 years. The so-called 'Krack' attack has been described as a “fundamental flaw” in wireless security
techniques by experts. Apple, Android and Windows software are all susceptible to some version ..."
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 ...

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 ...
