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.

"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 ..."
"Researchers at the National Institute of Standards
and Technology (NIST) have demonstrated that
quantum physics might enable communication and mapping in locations
where GPS, cell phones, and radio is not reliable or don't work at all, such as indoors,
in urban canyons, underwater, and underground. NIST announced the technology advance
on January 2. The technology may have marine, military, and surveying applications. The
NIST team is experimenting with very low frequency (VLF) digitally modulated magnetic
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 ...

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 applications 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 ...

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
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 ...

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
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 guy has been
outwitted by his wife, who evidently has a bit of tech savvy working for her ...
