"The Danish automotive designer behind cars like the
Aston Martin V8 Vantage and the BMW Z8 re-launched his electric car startup this year and
announced that the next car out the gate would be powered by a 'breakthrough' in solid state
batteries, one with a range of 500 miles and a charge time of one minute. Originally, Fisker
and his team were intending to use a brand new
graphene-based hybrid supercapacitor technology but eventually settled
on the standard lithium-ion instead. However ..."
Free webinar title: "Antenna Design for a Connected Home Multimedia Device." When: November
21, 11:00 am EST. Presenter: Dr. Marc Rütschlin. "As the Internet of Things establishes itself,
more and more connected devices are finding their way into the modern home. The 'connections'
are of course wireless and antennas are the key enabling technology which provides that wireless
connectivity. This webinar will discuss the case of a smart projector, exploring how antennas
can be designed given the ..."

Brigadier General David Sarnoff's name was well known
to most people in the realm of communications up to the time of his death in 1971. His technical
and leadership skills were recognized and rewarded throughout his very accomplished lifetime
in both military and civilian venues. This brief biography of Sarnoff was printed in the March
1972 issue of Popular Electronics magazine. As with many people of high acclaim,
he had a few run-ins with other notable people during his career - the most famous of which
was the Battle of the Airwaves fought between Edwin Armstrong and him over FM versus AM ...
Well, these are the last three Radio Service Data Sheets
I have from my collection of vintage electronics magazines. That makes a total of 219 that
I have scanned and posted over a span of 3 years. At some point I will bid for other editions
on eBay. They can cost $5 or more apiece, so the cost adds up quickly.

Saelig Company has introduced Siglent's
of Dual-Channel Pulse / Arbitrary Waveform Generators (AWG) that create test signals up to
500 MHz using a sample rate of 2.4GSa/s and 16-bit vertical resolution for an 80dB dynamic
range. This series features Siglent's proprietary TrueArb and EasyPulse technologies that
solve the weaknesses inherent in traditional DDS waveform creation. TrueArb technology generates
arbitrary waveforms "point-by-point" to produce a very low jitter output signal from stored
In his trademark style, electronics-themed storyteller
John T. Frye used his Mac's Service Shop venue to introduce readers to another new development
medical electronics field - the "ultrasonoscope." It was the forerunner to modern sonogram
machines. Relatively recent advances in solid state electronics and signal processing techniques
- albeit mostly analog in nature - made design and construction of compact devices practical
and affordable by medical facilities. Unlike today where many doctor's offices have their
own x-ray and sonogram machines, it was still mostly hospitals that owned them in the late
1960s when this piece was written. Mac McGregor schools ...

Akin to how the National Company ran a long series (
a couple hundred altogether) of infomercial type ads in the ARRL's QST magazine from
the 1930s through the 1950s, Mallory had its "Tips
for Technicians" run in Electronics World (and maybe other electronics magazines
of the era). Being a major capacitor manufacturer, its ads featured brief tutorials on various
types of capacitors, their characteristics, and how they should be used in circuits - both
for new design and when replacing capacitors in existing equipment ...

"Scientists at the National Institute of Standards
and Technology (NIST) have developed an underlying architecture for a new class of
quantum photonic circuits - chip-based devices that leverage the quantum
properties of light to process and communicate information. In research described in the journal
Nature Communications, the NIST researchers and their collaborators in China and the UK developed
a class of devices that are composed of networks of low-loss waveguides and single-photon
sources, all on a single chip ..."
"Researchers at the University of Washington have found
a way to make clothes smarter without on-board electronics using a new type of data-storing
fabric that leverages technology already found in smartphones. One limitation to wearable
technology is the need for electronics and wiring that make so-called
'smart' clothing not so comfortable to wear. Researchers at the University
of Washington have found a way to make clothes smarter without on-board electronics ..."
"Researchers from the Cambridge Graphene Centre have
led a project that has successfully demonstrated printing of fully-integrated electronic circuits
directly onto fabric for the first time. The circuits, which contain complex layered semiconductor
devices, are printed using inks containing graphene and a similar two-dimensional conductive
material, hexagonal boron nitride (h-BN). Previous attempts at printing electronics on fabric
are have used inks containing metal oxides ..."
"Scientists aren't normally treated to fireworks when
they discover something about the universe. But a team of University of Chicago researchers
found a show waiting for them at the atomic level - along with a new form of
quantum behavior. 'This is a very fundamental behavior that we have never
been seen before; it was a great surprise to us,' said study author and professor of physics
Cheng Chin. Published Nov. 6 in Nature, the research details a curious phenomenon - seen in
what was thought to be a well-understood system - that may ..."
"A seemingly paradoxical prediction in physics has
now been confirmed in an experiment: No matter whether an object is opaque or transparent,
average length of the light's paths through the object is always the same. What happens
when light passes through a glass of milk? It enters the liquid, is scattered unpredictably
at countless tiny particles and exits the glass again. This effect makes milk appear white.
The specific paths that the incident light beam takes depend, however, on the opacity of the

"As our cars turn into rolling supercomputers, it's
easy to forget one of their emerging electronic needs: managing massive data flows within
the car. In a self-driving car, sensors should throw off some 4 terabytes a day. 'Connectivity
is one of the missing elements,' says Micha Risling, head of the automotive business at Valens,
a fabless semiconductor company in Israel. 'On one hand you have the Nvidias of this world
- the companies that offer processing solutions - and, on ..."

Radio control hobbyists realized a huge technology
advance with the introduction of solid, proportional control system that began appearing in
the late 1960s. Prior to then, most R/C systems used vacuum tubes and necessary accompanying
large, heavy batteries. Size and weight was not too big of a deal for the transmitter, but
both factors significantly impact airplane design and performance. The new systems enabled
smaller, lighter weight aircraft that not only cost less, but flew better. Of course other
forms of R/C modeling like boats and cars also benefitted from the advances, but weight and
size was not as ...
Mr. Al Rabassa (NW2M) had a great letter in the
November 2017 issue of the ARRL's QST magazine titled, "Saving the Neighborhood." In it, he described how his proactive response
to a new neighborhood with houses full of poorly designed arc fault circuit interrupter (AFCI)
circuits breakers resulted in him being regarded as a hero (of sorts) rather than as a bad
guy. Only ARRL members can access the online version, but fortunately Mr. Rabassa placed a
copy of it on his Yaesu FT-101
