00) --commentary--
Have been working for awhile now on learning basic electronics
and wanted to share an entry-level recommendation for those
who have some basic knowledge, and want to learn programming
(variant of BASIC) and how it ties into electronics/hardware,
in an excellent educaitonal, self-learning format. will be
sharing more ideas of how one might begin learning more about
electronics, yet nothing seems to encapsulate everything in
one approach. Even this. Yet, robotics and areas where the
Parallax BasicStamp is being used are where things are coming
together, hardware/software/programming & electronics/invention,
and to consider one can learn about microcontrollers, and also
program one (to control a solderless (or soldered) breadboard)
is quite incredible as a potential for learning electronics.
This is not the only approach, yet if one is ready to jump in
this is a way to realize the potential in learning electronics...

China, U.S. lead burst in oil demand; prices remain volatile
<http://www.startribune.com/stories/535/4261305.html>
'With China's economy expanding rapidly and a recovery simmering in
other countries, demand for oil will increase faster than expected this
year and in 2004, the International Energy Agency said Wednesday.' ...
'Demand has surged this autumn in the United States and several other
industrialized nations, while Chinese demand appears to be advancing
"at a breakneck pace," the agency said in its monthly oil market
report.' ... 'Chinese demand for crude jumped by 11.5 percent in
October, though growth will slow as China becomes constrained by limits
on its capacity to generate electricity, the agency said.' .. '"The
pull from the Far East has taken over from the typical U.S.-centric
focus as the key driver for the oil market," it said.' .. 'Paul
Horsnell, head of energy research at Barclays Capital in London, agreed
that China's thirst for oil imports has become a significant factor in
world markets. China is a top oil importer after the United States, and
both countries are leading the world economic recovery.' .. '"It's been
quite a while since we've seen the Chinese and U.S. economies going on
all cylinders," Horsnell said.'

Research Generates Reliable Energy Source During Outages // ***
<http://www.sciencedaily.com/releases/2003/12/031210072849.htm>
'Researchers from the College of Engineering have designed a system
where a small network of local generators can reliably disconnect from
the rest of the power supply, enabling locations where electricity is
critical to stay in operation.' ... 'The UW-Madison technology consists
of a microgrid, a small network of several power generators located at
a single site. These generators, integrated into the main energy
distribution system, encompass a wide range of power sources, including
micro-turbines, gas internal combustion engines, fuel cells and
photovoltaic, which generates voltage from light exposure.' .. 'When
problems occur within the transmission lines, the generators and their
loads (the devices each one powers) can separate from the main
distribution system to isolate particular areas - hospital rooms or
factory floor, for example - from the disturbance.' ... 'Besides
sidestepping possible power outages, the microgrid system is more
energy efficient.'

Seeking Balance: Growth vs. Culture in Amazon // SUVs + Ecuador's oil
<http://www.nytimes.com/2003/12/10/international/americas/10AMAZ.html>
'As international energy companies move into the Amazon basin to tap
some of the last untouched oil and natural gas reserves, more and more
natives are fighting to keep them out.' ... 'How this struggle plays
out will determine whether Amazon resources become a critical part of
Latin America's development and an important component of the American
strategy to diversify energy supplies beyond the Middle East.' ..
'Latin America already provides more oil to the United States than the
Middle East does. Plans for new oil and gas fields are speeding ahead,
pushed by companies from as far afield as China and including
Occidental Petroleum of Los Angeles, Repsol-YPF of Spain, EnCana of
Canada and Petrobras of Brazil.' ... 'That future will be increasingly
uncertain and conflict-ridden, many oil executives concede, without
some compromise and compensation for the Indians who live there.' // ~

Mars Mission's Invisible Enemy: Radiation // ***. concrete/lead+earth
<http://nytimes.com/2003/12/09/science/space/09RADI.html>
'In a new $34 million NASA laboratory here, part of Brookhaven
National Laboratory, scientists are using subatomic particles
accelerated to nearly the speed of light to slam into materials that
could be used in a spaceship, and tissue samples and small animals.
Using tools like PET and M.R.I. scans and DNA sequencing, they hope to
shed light on ways that radiation damages biological tissue, and what
can be done about it.' .. 'On a trip to Mars and back, probably every
cell in the body would be hit by an ionized particle or a proton,
researchers say, and they have very little idea what that would do. "If
every neuron in your brain gets hit, do you come back being a
blithering idiot, or not?" asked Dr. Derek I. Lowenstein, the chairman
of Brookhaven's collider accelerator department.' ... 'A round trip to
Mars would be of a different order of magnitude. Brookhaven puts the
exposure at 130,000 millirem over two and a half years. That is
equivalent to almost 400 years of natural exposure.'

because it contains fine particles of a magnetic material called
nickel-zinc ferrite. When an electromagnetic wave hits the ferrite
particles, the magnetic part of the wave is absorbed.' ... 'The

Saving The Data Deluge For Posterity's Sake // 'digital junkyard'
<http://www.forbes.com/2003/12/10/cx_ah_1210tentech.html>
'Think it's an easy job saving all this data? One study by researchers
at the University of California at Berkeley says the amount of
information produced every year is equal to about 800 megabytes per
person--that is, every person on the planet. That includes information
stored on paper and in digital form. And it has been growing at a rate
of about 30% every year.'

Hope You Like Jamming, Too
Cell-phone jammers may soon be all over. // and, cellphones as bugs...
<http://slate.msn.com/id/2092059/>
'A cellular "security bubble" in London could have protected Bush from
a very real threat: terrorists who use cell phones to detonate bombs
from miles away, or even another country. By connecting a cell phone to
hidden explosives, and then calling that phone, one can detonate a bomb
(the electrical charge that activates the ringer on the cell phone
serves as the triggering signal).' ... 'The physics of jamming a cell
phone are actually quite simple. Cell phones operate by sending signals
along a range of the electromagnetic spectrum reserved for their use.
(In the United States that part typically is measured as either 800 or
1,900 megahertz; in Europe it's usually 900 or 1,800 megahertz.) All a
cell-phone jamming device needs to do is broadcast a signal on those
same frequencies, and it will interfere with any devices trying to
transmit in that range. The net effect for a hapless cell-phone user?
The phone's screen will simply indicate that no signal is available.
Odds are most people won't even notice that their phones are being
jammed. They'll just assume that they're in a dead spot—and feel
annoyed.'

<http://www.securityfocus.com/news/7517>
'Though ATMs typically sit on private networks or VPNs, the most
serious worms in the last year have demonstrated that supposedly-
isolated networks often have undocumented connections to the Internet,
or can fall to a piece of malicious code inadvertently carried beyond
the firewall on a laptop computer.' ... '"I think of ATMs as a relative
of SCADA systems, as those things not really being on the Internet,
but being on some network," says Peter Lindstrom, an analyst with Spire
Security...'
Inherent insecurity
Now that desktop PCs have put a veritable petri dish for viruses on
every desk, the only sure-fire answer is to remove the nutrients.
<http://news.com.com/2010-7355_3-5118280.html>
'The nutrients are program code on the client machines. All
applications should be executed on secure servers and merely have their
user interfaces displayed on the desktops. That would leave nothing for
viruses to attack on the desktop, which makes them less destructive to
users and far less able to propagate.' ... 'How the thin-client
approach will play out in practice is still unclear.'

technical and legal flaws, relating to data protection and privacy, in
the security system used to control access to the UN Summit. The system

LEDs Are Still Popular (and Improving) After All These Years:
This article discusses a 35-year-old display technology that
itself has rapidly changed — the LED. This overview covers
the origins of LEDs, the traditional applications, and how
improvements in the technology have stimulated new applications.
<http://www.maxim-ic.com/appnotes.cfm/appnote_number/1883/ln/en>
'The Commission Internationale de l' Eclairage (CIE) formalized
standards for the measurement of light, and the response of the human
eye or "standard observer", back in the 1930s. These standards
characterized the variation in eye response over the entire visible
range under a variety of lighting conditions, such as daylight and
night. The CIE also defined the primary colors (Table 1).'
'Table 1. CIE Definition of Colors'
Color Name Wavelength
Red 700nm
Green 546.1nm
Blue 435.8nm
'LEDs are processed in wafer form similar to silicon integrated
circuits, and broken out into dice. Chip size for visible signal LEDs
generally fall in the range 0.18mm square to 0.36mm square (Figure 3).
InfraRed (IR) LEDs can be larger to handle peak powers, and LEDs for
lighting are larger again.'

Earth Radiation Belts Spectacular Following Halloween Solar Storm

'"We have been observing the Van Allen Belts for over 11 years with
the SAMPEX spacecraft," said Baker. "We have never seen such a powerful
enhancement and distortion of the radiation belts during the lifetime
of SAMPEX. Baker noted that the center of the outer Van Allen belt is
usually about 12,000 miles to 16,000 miles away from Earth's surface,
as measured above the equatorial region of the Earth.' ... 'During the
Halloween storm, the Van Allen radiation was greatly increased and
pushed inward toward Earth's surface to an unusually close degree.
"From Nov. 1 to Nov.10, the outer belt had its center only about 6,000
miles from Earth's equatorial surface," he said. "This is a place where
ordinarily there are almost no energetic electrons at all."'

Nanoguitar May Fine-Tune Telecom // NEMs = nanoelectromechanical
Cell phones and other wireless devices usually use quartz crystal
oscillations to generate the carrier wave on which they transmit or
tune into an incoming signal. A tiny vibrating nanorod could do
the same job in far less space, drawing only milliwatts of power.
<http://www.newsfactor.com/perl/story/22837.html>
'Researchers can tune nano-oscillations to a very narrow range of
frequencies -- an electronics property called "high Q" -- making
nanostrings useful as filters to separate signals of different
frequencies.' ... 'Devices shaped like harps, xylophones, guitars,
violins or drums make great tools for Craighead's research group when
they study resonance and vibration.' .. 'The guitar shape was "an
artistic expression by the engineering students," Craighead told
NewsFactor.' .. 'The ability to make tiny strings vibrate at very high
frequencies offers many potential applications in electronics,
Craighead added.'

EM-QUOTE from Daylight-deprived? Look with hope to the setting sun
<http://www.startribune.com/stories/462/4261066.html>
'The "equation of time" is the name scientists have given to the
difference between the clock's noon and solar noon. The spread can be
as much as 16 minutes during some parts of the year.' .. 'The elaborate
equation helps explain why the sunsets seem -- on our clocks, at least
-- to turn around before the solstice. We have, over the centuries,
developed clocks that are more regular than the sun. If we tried to
live by true solar time, we could be frustrated in trying to catch a
plane or meet a friend for lunch.' ... 'Over the centuries, our passion
for order has driven us to adapt to our irregular relationship with the
sun. We adopted leap year to adjust for the fact that the Earth
revolves around the sun in 365.2422 days. We gave up sundials in favor
of clocks that run at a steady "mean" solar time, not the true, more
erratic, time.' .. '"As long as you live by the clock, you have order,"
said Robert Gehrz, another astronomy professor at the University of
Minnesota.'

Anthrax Powder: State of the Art? // 'charged questions'. nanatech?
<http://cryptome.org/anthrax-powder.htm>
'There is no debating that the Senate powder was exceptionally pure
and highly concentrated. Nor is there any doubt that it contained the
Ames strain, one of the most virulent strains discovered. But what made
it truly remarkable, according to biodefense specialists, was its
conversion into a cutting-edge aerosol.' .. 'That transformation had as
much to do with chemistry and physics as with microbiology. Anthrax
spores cling to one another if they get too close; sticky chains of
proteins and sugar molecules on their surfaces latch onto each other,
drawn by van der Waals forces that operate at a distance of a few tens
of angstroms. Untreated spores clump into larger particles that are too
heavy to stay airborne or reach the narrowest passages in the lung.' ..
'In a separate research arena, pharmaceutical scientists in the 1990s
began experimenting with adding electrostatic charges to small
particles in medicinal powders designed for inhalation. Adding a like
charge of sufficient strength creates an electrostatic field of up to a
few centimeters, which makes particles repel one another, creating an
"energetic" or self-dispersing powder.'' ... 'The Senate anthrax spores
carried like electrical charges, and some experts believe that they
were added deliberately to aid dispersal.' ... '[Alibek's] theory
raises a question: Why would only the Senate powder acquire a charge
from the sorting machines?'

matter of grave concern to terrorism and nonproliferation experts who
know the damage such devices could do. A dirty bomb is not a nuclear
device but a weapon that uses conventional explosives to disperse
radioactive materials, which could cause widespread disruption and
expose people to dangerous radiation. Unlike other kinds of dirty
bombs, this one would come with its own delivery system, and an 8-mile
range. A number of terrorist groups, including al Qaeda, have sought to
build or buy one.'
