Arduino experimenter sets are big boy (and girl) versions of those
basic electronics kits with the spring terminals and an assortment of Rs, Ls, Cs, a switch,
and light bulb or two. This particular kit includes more than 200 pieces, including the
Arduino processor board for $60 - an amazingly good deal (lesser kits start at around
$35). A huge variety of add-on sensors and functional modules are available at dirt cheap
prices. Here is a set of
37 modules such for $29. You can also get application-specific Arduino
kits like this one for
RFID development or for a
smart robotic car. There's no time like the present to get started.
Did you know that Mallory, the well-known capacitor
maker, at one time was at the forefront of solid state rectifier diodes? Not me, at least
before seeing this infomercial from a 1969 Electronics World magazine. I
know that they made selenium rectifiers that replaced many application which formerly
required vacuum tubes. This installation of Mallory's "Tips
for Technicians" is one of many run for the benefit of service shop guys who needed
to keep abreast of changes in technology. Note the admonition at the end: "Don't forget
to ask 'em - 'What else needs fixing?'" ...

"Residents of southeast Michigan were left a bit
shaken Tuesday night after a big bright flash lit up the sky and the ground beneath them
shook. A flying saucer? No. A shooting star? Not quite. The National Weather Service
eventually solved the mystery, tweeting 'USGS confirms
meteor occurred around 8:10 pm, causing a magnitude 2.0 earthquake.'"
The science-challenged reporter (as are most) got the part about it not being a shooting
star wrong, though. A 'shooting
star' is a meteor, although it is not a star ...

"Intel has passed a key milestone while running
alongside Google and IBM in the marathon to build quantum computing systems. The tech
giant has unveiled a superconducting quantum test chip with
49 qubits: enough qubits to possibly enable quantum computing that
begins to exceed the practical limits of modern classical computers. Intel’s announcement
about the design and fabrication of its new 49-qubit superconducting quantum chip, code-named
Tangle Lake, came during a keynote speech by Brian Krzanich, Intel's CEO, during ..."
Prior to the big push for leadless solder in the
1990s, probably 99% or more of the solder used by industry, tradesmen, and hobbyists
contained lead. The
60/40 Sn-Pb (and 63/47) alloy, both with and without a rosin or acid core, was used
for electrical work, electronics, plumbing, copper guttering, radiators, and many mechanical
assemblies made of steel, brass, copper, tin, etc. Between World War I, "The War
to [Not] End All Wars," and World War II, the electronics industry exploded in growth.
All realms of society and government became utterly dependent on products assembled using
solder. Both tin and lead were abundantly available ...
"In a paper titled 'Deterministic Line-Shape Programming
of Silicon Nanowires for Extremely Stretchable Springs and Electronics' published in
the Nano Letters, an international team of researchers from Nanjing University, Peking
University, and CNRS-Ecole Polytechnique has demonstrated a new route to designing silicon-based
flexible electronics in a scalable way. Rather than starting from Si wafers cut-out from
drawn silicon ingots, they describe in their paper a nanoscale-version of the crystal-pulling
methods used to grow silicon ..."

"China has been leading the world in construction
of solar energy plants, building dozens of new solar farms over the past few years. In
addition to building standard solar farms, the country has also been experimenting with
more innovative ways to draw energy from the sun. Recently, the city of Jinan built China's
solar road, which lasted about a week until someone stole it. The
road opened on December 28, and on January 2 an inspection team noticed a piece of the

According to author R.R. Freeland, manufacturing
processes for radio-quality manmade crystals saw major improvements toward the end of
World War II. At the time, the process was highly manual-intensive, as can be seen
in this really nicely done 1940s video titled "Crystals Go to War." Prior to the use
of crystals as frequency-determining devices, inductor-capacitor (LC) tank circuits were
the dominant configuration. There were actually other frequency-determining schemes like
spark gaps and even vibrating mechanical reeds. As you might guess, anything less than ...

"Many engineers possess unique traits such as initiative
and eagerness to learn that help make them more successful in their careers.
Effective engineers use their resourcefulness and initiative to find
solutions. They identify problems, but they aren't limited to finding, fixing, and troubleshooting.
They assess their current situations and continually seek to improve upon the status
quo. They listen and learn. They ask for ideas, consider possible solutions, and then
synthesize opinions and facts to create appropriate responses. Here are some essential
qualities found in the most successful engineers ..."

TGIF. If this past week has had you on edge, cheer
up -the weekend's almost here. Once the final fire has been put out - or is at least
contained - give yourself a break and enjoy these
tech-themed comics from a vintage issue of Electronics World magazine. My
favorite is the one on page 83 which is a takeoff on the well-worn comedy meme of the
husband trying to sneak back into the house after a night out with the boys. This poor

"There's more to creating a PCB prototype than
meets the eye. Do you have any PCB prototype successes or disasters that you would care
to share with the rest of us? Many of my friends are involved in designing silicon chips
in the form of ASICs, ASSPs, and SoCs, so if you say 'prototyping' to them, it means
something very different to someone who wishes to create a prototype of a design that
will be realized on a printed circuit board (PCB). In this column, we will consider four
of the things that you really should consider before prototyping PCB ..."
Nuclear energy was a big topic in the 1960s and
1970s as it was believed to be the future of electrical power generation for the world
(at least up until the 3 Mile Island and Chernobyl incidents occurred). Ships and submarines
were being powered by reactors that allowed them to run for months at a time without
refueling, atmospheric emissions were practically zero, and the fuel source was abundant
(albeit not simple to obtain). Medical and space applications were increasingly dependent
on a greater knowledge of radiation and its effects on humans, plants, animals, and electronics.
Many people by that ...

off the atoms of yttrium manganite. The material was heated to 3,000° Fahrenheit ..."
"You don't have to be perfectly organized to pull
off a wave, according to scientists. Using a set of gyroscopes linked together, physicists
explored the behavior of a material whose structure is arranged randomly, instead of
an orderly lattice. They found they could set off one-way ripples around the edges, much
like spectators in a sports arena - a 'topological wave,' characteristic of a particularly
unusual state of matter. Using a set of
