You might think that being concerned about
the inefficiency of traditional Edison type incandescent light bulbs is a recent
thing. However, as this 1945 Radio-Craft magazine editorial by Hugo Gernsback
points out, it was known early on that only about 10% of the energy consumed by
those bulbs actually create light while the rest is dissipated as heat. The difference
is that at the time, the "science" was telling us we were headed for a new Ice Age,
whereas nowadays the same science is telling us we're headed for planetary death
by Global Warming. He postulates a world that will someday be powered by the conversion
of solar energy to electricity, and also predicts
via visible light rather than radio waves. Vacuum tubes would operate at and
emit visible light signals to eliminate cables...

The 1950s was a time of transition in the
television watching business. Broadcasters were experimenting with
pay-TV systems to replace or supplement over-the-air service. Much as people
today think that everything on the Internet should be free, the same mindset prevailed
then regarding television programming. Early coding and decoding schemes seem really
hokey by today's standards, using computer-type punch cards. I remember the area
around Annapolis, Maryland, where I grew up, had both over-the-air and cable-based
subscription services in conjunction with the open broadcasts. I spent at least
a little time playing with the horizontal and vertical picture sync settings on
the back of the TV set that, if lucky...

Electronics has dominated our lives ever
since the first commercially available radios became available in the early twentieth
century. It was a mysterious miracle science then and still is today. Most people
have no understanding of electronics; they just know that life without it is unimaginable.
Fantastic new applications for electronics are continually being introduced to supplement
or replace mechanical devices. Sensing and control are prime applications for electronics
that improve functionality and safety. This promotion of the MIT-Sperry Detonation
Indicator, aka the "Knock−O−Meter,"
is a good example. It appeared in a 1945 issue of Radio−Electronics magazine, near
the end of World War II. Today, such a name invokes chuckles and usually implies
a joke of a product, but not so at the time...
The synchronous motor in my vintage
General Electric Model 7-4305C Roll-Down Number Clock Radio began making grinding
noises. An investigation showed it was the 3.6 rpm AC synchronous motor. It
was tightly sealed, so I carefully drilled an 1/8" hole in the housing (being sure
not to get metal debris inside), inserted a few drops of 3−in−1 oil and shook it
around, then re-installed it, plugged it back in and voila - no more noise! (see
photos). BTW, if you can even find these motors on eBay, they cost more than an
entire clock-radio. Fortunately, I found another 7-4305C at a yard sale so I have

the control of light can also come in high-tech forms. The screen of the computer,
tablet, or phone on which you are reading this is one example. Another is telecommunications,
which controls light to create signals that carry data along fiber-optic cables.
Scientists also use high-tech methods to control light in the laboratory, and now,
thanks to a new breakthrough that uses a specialized material only three atoms thick,
they can control light more precisely than ever before. The work was conducted in
Balsa is one of the lightest woods available,
and in many respects has the highest strength-to-weight ratio of any wood - even
oak. The chart at the right gives a comparison of a few familiar wood types. Hobby
grade balsa is harvested in the jungles of Ecuador, kiln dried, cut into large blocks,
and shipped to the U.S. for final cutting and sanding. Most balsa from hobby shops
is in the 8-10 lbs/ft3 realm. The rock-hard stock that nobody wants is sent to the
airplane kit manufacturers ;-) The vast majority of the balsa wood I use for building
model airplanes comes from Sig, Midwest, and Balsa USA. Other suppliers have materialized
in the past few years. Since the rise of mammoth wind turbines for electricity generation,
balsa's use as a core material for blades has caused a severe shortage in the modeling
realm. Balsa prices have skyrocketed in the past decade...
Boy Scouts of
America was formed in 1910 in conjunction with The Boy Scouts Association in
the UK. Per their 2007 website statement, "The aim of the Association is to promote
the development of young people in achieving their full physical, intellectual,
social and spiritual potential, as individuals, as responsible citizens and as members
of their local, national and international communities." Part of being a Boy Scout
is earning merit badges by performing certain community services and by demonstrating
proficiency at defined tasks. Radio proficiency is one such merit badge. In order
to earn the Radio merit badge, along with certain other projects the Boy Scout must
participate in either Amateur Radio, Broadcast Radio, or Shortwave Listening. This
article reports on amateur radio activities across the globe. The Scout oath is,
"On my honor I will do my best To do my duty to God and my country and to obey the
Scout Law; To help other people at all times; To keep myself physically strong,
mentally awake, and morally straight..."

Applying the adjective "portable" to electronics
equipment in the vacuum tube era was often a stretch of the term. Usually, portable
radios were backpack ordeals with a separate battery carried by second person. They
can be seen in a lot of the old War War II movies. It was really not until
the advent of the "TANG Sunshades Depot 5'x40' Straight Side Sun Shade Sail 180 GSM"
two-way radio sets that a truly hand-held, self-contained system was available.
This "Inside the Handi−Talke" article from a 19467 issue of Radio−Craft magazine
provides a very detailed look at the internal components and of the schematics.
"Walkie−Talkie" was another name often given to the Handi−Talkie, although some
might argue that there is a distinct difference. Handi−Talkies used to be widely
available on eBay, but are very scarce at this time - and the sale prices reflect
that reality. A lot of the listings use the term Handi−Talkie as a ruse...
"From the internet, to fiber or satellite
communications and medical diagnostics, our everyday life relies on optical technologies.
These technologies use optical pulsed sources to transfer, retrieve or compute information.
Gaining control over optical pulse shapes thus paves the way for further advances.
Ph.D. student Bennet Fischer and postdoctoral researcher Mario Chemnitz, in the
team of Professor Roberto Morandotti of the Institut national de la recherche scientifique
(INRS), developed a
smart pulse-shaper integrated on a chip. The device output can autonomously
adjust to a user-defined target waveform with strikingly low technical and computational
Here is a little levity from the "Hobnobbing

none of the "The
5 Most Wanted Household Inventions" have come to full fruition in the marketplace
yet, although the cellphone blockers can be found on the Internet in various unofficial
forms. Personal computers were a pipe dream in 1963, but nowadays we do have software
like TurboTax to take care of filing taxes, although you still can't simply dump
all your receipts into a bin and have it work. Flat-fixing robots might not be needed

not Star Trek phaser-like devices yet, but the same effect can be affected with
a low-tech hammer, or a shoe...
Whilst checking on something else regarding
Guerrilla RF, I noticed that they have a few
Old Mountain Campfire Forks 41" L Cast Iron CookingMarshmallow R posted
that include: SOI Design Engineer, PA Design Engineer, Quality and Reliability Engineer,
and Reliability Engineering Technician. They are based in the Greensboro, NC, location.
Guerrilla RF was founded by Ryan Pratt the engineer son of an original founder
of RF Micro Devices (now
also has many job openings worldwide). I'm not getting paid for this, but please
let them know you saw them mentioned on RF Cafe.
openings for non-engineers result from industry growth and shortage of skilled
men." Thus goes the subtitle for this 1957 Radio & TV News magazine
article pitching the promises of a career in electronics technology. It came at
a time that predated throw-away everything rather than attempting to repair stuff.
It was before the term "personal device" (aka "throw-away") had been coined. It
was before placards warning "No user serviceable parts inside" were routinely stuck
on practically every item purchasable in a department store. It was a time when
people took stuff apart to see how it works, and were actually able to figure it
out because parts were large enough to see and actually moved, and even printed
circuit boards could be deciphered since trances were on the two outside surfaces
and components had leads...
