Mac and Barney discuss with some degree of trepidation
the alarmingly increasing rate at which new
electronics technology is being developed and marketed. As service shop owner and
technician, respectively, they needed to constantly educate themselves on new components
and circuits in order to stay current and be efficient enough to turn a profit. Mac recounts
his lengthy background beginning with the days of mainly battery-powered AM radios, and
progressing through AC-DC, FM and all-band (shortwave) radio, B&W television and
the color TV, CB radios, and a new breed of appliances with electronic controls ...
"The U.S. communications agency says tiny Internet
of Things satellites from
Swarm Technologies could endanger other spacecraft. On 12 January,
a Polar Satellite Launch Vehicle (PSLV) rocket blasted off from India's eastern coast.
While its primary cargo was a large Indian mapping satellite, dozens of secondary CubeSats
from other countries traveled along with it. Seattle-based Planetary Resources supplied
a spacecraft that will test prospecting tools for future asteroid miners ..."

"A new method to produce large, monolayer single-crystal-like
graphene films more than a foot long relies on harnessing a 'survival
of the fittest' competition among crystals. The novel technique, developed by a team
led by the Department of Energy's Oak Ridge National Laboratory, may open new opportunities
for growing the high-quality two-dimensional materials necessary for long-awaited practical
applications. Making thin layers of graphene and other 2D materials on a scale required
for research ..."
Photodiodes and phototransistors were relatively
new on the electronics scene in 1969 when this article appeared in Electronics World
magazine. Prior to semiconductor light detectors, vacuum phototubes did the job in cameras,
motion sensors, light level detectors, medical imaging equipment, etc. High voltages
and the large volume for containing components supporting vacuum tubes created hazards
(especially with medical equipment), inconvenience, and high cost. What we take for granted
nowadays in terms of price, performance ...
"Temperatures below 3 millikelvin can be maintained
for seven hours. High-tech refrigerators have been used to reach temperatures as close
to absolute zero as possible - 0 kelvin or −273.15 °C. Physicists aim to cool
equipment to as close to absolute zero as possible, because these extremely low temperatures
offer the ideal conditions for quantum experiments, and allow entirely new physical phenomena
to be examined. A
nanoelectronic chip was successfully cooled to a temperature lower
than 3 millikelvin using ..."
Rohde & Schwarz is offering at no cost a variety
of reference charts (posters) for hanging on your lab or office wall, and some handy-dandy
In the current age of (seemingly) paperless offices and laboratories, opening a cardboard
package from R&S containing the pictured items caused me to wax nostalgic over the
days when sales reps handed out such materials during workplace meetings and at trade
shows. Wall charts are still fairly easily obtained, but the spiral-bound pocket guides
are more rare. Maybe soon we'll be seeing the resurrection of cardboard slide rule calculators ...

"U.S. researchers have made on-chip inductors
smaller by adding 'kinetic inductance' to conventional magnetic inductance. The work
cuts the size of 10-50 GHz inductors by a third. Kinetic inductance arises from
the physical momentum of charge carriers resisting the change in current direction associated
with a change in electric field, according to the team, from the University of California,
Santa Barbara. Any kinetic inductance created appears in series with the conventional
magnetic inductance of the inductors ..."

Although the article's title specifies "electronic
hobbyist," the advice applies equally well to students and professional technicians and
engineers. A few of the
tools are no longer available from the original manufacturers, but modern equivalents
- often of better design and quality - are available. If you are nostalgic for the originals,
though, you can always look for them on eBay; there's not much you cannot find there
if you wait long enough. To show how much times have changed, get a load of (pun intended)
that pistol-shaped soldering gun. Can you imagine the mayhem that would ensue if it ...
"It's probably no surprise that the
job outlook for engineers is positive. In a January Bureau of Labor
Statistics report, employment in the electrical and electronics space is expected to
grow seven percent by the year 2026. To capitalize on the country's economic growth,
organizations are expanding and looking for more workers to fill traditional roles in

"For most of the world a motorcycle or a scooter
is a basic means of transportation. Cheap to purchase and operate, and easy to park on
crowded city streets, commuting on two wheels is a way of life. This is especially in
emerging markets where a motorcycle or scooter is an attractive alternative to a bicycle,
a public bus, or walking. In the 1950s and 1960s in the U.S., motorcycles had a utilitarian
purpose too, but somehow, during the 1980s and 1990s, motorcycles, and in particular
Harley Davidson motorcycles, became lifestyle ..."
"According to researchers at Oregon State University's
College of Engineering, vertical structures are difficult to print with a liquid metal
due to the low viscosity and high surface tension of the gallium alloy. The team in the
college's Collaborative Robotics and Intelligent Systems Institute put nickel nanoparticles
into galinstan, a liquid metal alloy, to thicken it into a paste with a consistency suitable
for additive manufacturing. According to the team, the resulting rheological modification
of the liquid metal ..."
David Corman, of Anokiwave, has a good article
silicon phased array antennas. This concept, using printed arrays,
is gaining popularity for providing steerable beams in WiFi hotspots, Bluetooth, small
cells, etc., where a dense communications environment generates too much ambient signal
presence for long enough range. Now, implementation in silicon for mm-wave antenna arrays
is being investigated. "Using active antennas allows highly-directive antenna beams to
be formed by physically-small apertures, which helps offset the higher path loss associated ...
To be or not to be - that is the question: Whether
'tis nobler in the mind to suffer the slings and arrows of outrageous bi-annual clock
shifts, or to take up arms against a sea of contradicting justifications for and against
the existence of DST, and by opposing, end it. Twice each year, a majority of the western
world is subject to a manmade disruption in circadian and habitual cycles with an inane
one-hour clock change on and off of "Daylight

"In the original
Maxwell's demon thought experiment, a demon makes continuous measurements
on a system of hot and cold reservoirs, building up a thermal gradient that can later
be used to perform work. As the demon's measurements do not consume energy, it appears
that the demon violates the second law of thermodynamics, although this paradox can be
resolved by considering that the demon uses information to perform its sorting tasks.
It's well-known that when a quantum system is continuously ..."

"The original arguments Congress made for 'springing
ahead' have been thoroughly debunked. So why are they still being used today? One hundred
years after Congress passed the first daylight saving legislation, lawmakers in Florida
this week passed the 'Sunshine Protection Act,' which will make daylight saving a year-round
reality in the Sunshine State. If approved by the federal government, this will effectively
move Florida's residents one time zone to the east, aligning cities ..."

Martin Rowe, over at EDN, has been "Mr. Test &
Measurement." I knight him with that title based on his many years writing for the long-ago
absorbed trade magazine Test & Measurement World. Mention of this article
was motivated by the photo of the small anechoic measurement enclosure by
octoScope. Note that it is not
a TEM cell, which is characterized by its tetrahedral shape and accommodates a wide range
of frequencies. octoBox is a special purpose, limited range test environment. As with
so many things these days, you can outfit just about any T&M setup with mostly prefabricated

The initial part of this article, The Sarasota
Mystery, appeared in the previous issue (March). Mr. Minto is still scratching his
head over hydronic communications ...
After reading both this article and "The
Sarasota Mystery First Follow-Up" article in the April 1966 issue of Popular
Electronics, I'm convinced that the inventor Wallace Minto either did not understand
the phenomenon he describes, or he's out to punk the reader. If this initial article
had been printed in the April issue rather than March, it almost certainly would have
to have been a Fool's scam. Minto believes he has discovered a new form of electromagnetic
propagation that exploits molecular / atomic properties of water to transmit the signal
- without attenuation and without picking up noise. If it ...
"Here's what I'd like to know: Is
short-range wireless really radio? Most of the wireless standards
we use daily are considered short-range technologies. The question is, just what is short
range? For standards like Wi-Fi, Bluetooth, ZigBee, Z-Wave, and others, it ranges from
a few feet up to 100 meters or so. The range varies widely with frequency, power level,
antennas, as well as many environmental conditions. These are radio technologies. Then
there are some wireless tech that have a very short range. Short ..."
