A dipole antenna, say lambda-quarter is in the order of 2.5km.
A focus won't be much smaller than this, provided that you
have a directional antenna such a 10 element Yagi. It is going

I think a stacked rombic is the way to go. The upside would be a beam
width of only about 3 degrees. The downside is needing to put it in orbit
because there isn't enough room on the earth.

Somebody here was trying to up with a simple circuit to measure inductance
values. I ran across such a thing in the 2000 Radio Amateur's Handbook.
Better yet, you can buy the kit from www.electronicrainbow.com . It goes
from 3 uH to 7 mH in two ranges. The oscillator runs at 6 KHz on one range,
and 60 KHz on the other. Output is a voltage proportional to L.

I believe there is a mistake in the ARRL schematic. The IC is probably
74HC132, not 75HC.

Hi:

Yesterday I went to the post office. Not yet fully adjusted to police
state living, I foolishly questioned to my wife about the poster on the
wall about "media mail." I asked my wife why it is that the government
should be able to "subject to inspection" and create a special category
of mail that is for shipping VCR tapes, CDs, DVDs, etc.

I wasn't quite sure if it was a manifestation of corporocracy, ie.
corporate controlled government that is now searching our mail to see if
we are violating copyrights, or if it had some other reason.

The truth on this is quite innocent. "Media mail" is something like an
extension of "book rate" - a discounted rate. Some people have taken
to mailing items that do not qualify for media mail as media mail to
save a few dollars, so the USPO must reserve the right to inspect the
packages or envelopes if you want to get the discounted rate.

Obviously, however, it is the attitude of your stranger that is most
troubling. Nobody really looks at hundreds of thousands of DVDs that
pass borders; information really can no longer be controlled except
perhaps the very immediate information that can only come by satellite
phone or other means where the infrastructure is controlled and
monitored. But your stranger was not thinking, only fearing. And
paranoid people do crazy, dangerous things.

We wound up in a discussion about Constitutional rights, and I asked her
some questions about Thailand, where in her experience it seems they
still generally respect people's right to not be searched without a
court order.

Then suddenly a guy jumped into our conversation, and said the
following: "frankly, right now I think that being safe is a lot more
important than Constitutional rights."

In a state of mild shock, I responded by asking "then what might be the
issue with media mail?"

He responded that "there might be people trying to ship government
secrets outside the country...you know there are still foreign powers
out there that are a threat to us." Then he walked away miffed, I
suppose about my unpatriotic expectation that the Constitution should
have something to do with life in America.

I was deeply saddened by this experience for the rest of the day. It
left me even more convinced that the end of liberty in America may be
just a few more months, weeks, or days away.

You call Windoze XPee "normal?"

Xp always boots from the first unhidden primary partition

on Disk 0 and then the boot.ini menu is presented on the screen.

If the item you select either points to a different partition
and/or physical disk, you will always see "system" and "boot"
partitions.

"System" is the partition where XP initially loads and where the

Actually, I don't object to X-raying or residue analysis types of
inspection. I don't consider that an invasion of privacy. If the
analysis reveals something, then there is a justification to further
inspect the package, or question somebody.

I think that inspecting "media mail" is different. Perhaps you have
brought up the real reason below:

There was a
time in this country when mail could and would be searched for
pornographic content,

It is probably about pornography, which is why I was perplexed because I
have no interest in it and forgot it existed since I've been spending
all my paranoia of late on the economy and general fears of future tyranny.

So... while I frown upon pornography, I still think it is wrong to
inspect media mail, unless there is some evidence that the sender is
involved in criminal activities, and then the search should be by
warrant, just like wiretapping used to be.

and even personal, hand-written love letters
that contained sexual references put real people in prison.

Really? Wow, that's bizarre.

There was
a time when criticizing the government in print was a crime.

And that is a sad thing. Just because it happened before doesn't make
it right.

There was
a time when blacks couldn't attend most colleges or enter professions,
and Chinese weren't allowed to own land. There was a time when women
couldn't vote. The US has never had more civil liberties and a freer
press than it has today.

Ok, point taken. We've made a lot of progress in a lot of areas. But
that doesn't mean we can't regress. Extreme fear and economic strife
are prime reasons, throughout history, for people to be susceptible to
gross decreases in their liberty. If we don't remain vigilant in
defense of freedom, it will be lost.


If you don't mail bombs or military secrets, you'll be fine. Or you
can use UPS for the subversive stuff.

Thanks for the suggestion.

Seriously, I find it hard to accept the argument that I'll be fine if I
do nothing wrong. The reason for Constitutional restraints on
government powers is because of at least these reasons: 1. they are
often abused for political or other nefarious purposes; 2. because
mistakes are made.

Couple together policies of not allowing people access to lawyers nor
charging them with a crime properly in the public record when they are
taken into custody for suspicion of having committed any sort of
national security related crime (and how convenient it them becomes to
redefine anything to be national security related, or any criminal
offense to be "terrorism"), and allowing searches and seizures without
warrant (and requiring anyone who provides info the government requests
to remain silent about it), and you have a recipe for life-destroying
nightmares for a few very unfortunate citizens in the best of
circumstances (if the political abuses do not occur, but only mistakes
are made), and outright tyrrany if these powers are abused for political
reasons (history suggests a very high likelyhood that they will be.)

Agreed, all the things I mentioned were clearly unconstitutional, and
were morally wrong, and most were stopped by the courts. I think the
courts will still protect us from excesses. Remarkably, no
administration or congress that I know of has ever defied a Supreme
Court ruling.

But the first part of the promise of "life, liberty, and the pursuit
of happiness" is life. I think even the courts recognize this.

There is some hope in that it appears the Supreme Court has struck down

It's called 'Zen'

Looking up the Hank-ism for Zen, its not quite what I had in mind. I
like the part about one-lip kissing ass. As with most religions, it
presumes reason is useless.

I'm probably (much) closer to a Taoist ("All asses and all dollars are
all part of something important. We'd tell you more but you should
figure it out yourself").

Anyway, my choice is Asatru.

Asatru is actually a good deal of fun, and you can't say that about most

Sounds like it, in the short-run anyways. And we're all dead in the long

Shyit, was is Los Alamos that nuclear secrets were just wandering off,

Can't they find enough American scientists? Judging from my personal

Like making old ladies take their shoes off and hassling people at

incompetent that make big shows and symbolic actions, while dumping the

Think of the Nazi and Soviet propaganda examples. All kinds of symbolic

Yes, lithium ion has different pyrotechnic properties than
lithium sulfur dioxide or lithium thionyl chloride. The latter
two types use metallic lithium and electrolyte that is the
actual reactant. Get them hot enough to melt the lithium
and you will get a big boom. These have about 1/3 the energy
density of TNT.

Lithium-ion doesn't use lithium metal, but lithium compounds,
the energy density is much less and the boom turns out to be
a pop and a fire.

Best regards
mark

All good points. The purpose of the post was to determine if events had
occurred similar to http://www.cdc.gov/niosh/face9939.html involving lithium
sulfur primary batteries.
These batteries do pose an explosion hazard. Imagine if the batteries in the
above case had been in a device cradled in a person's lap!
Perhaps the venting characteristics of LiIon batteries are different from
lithium sulfur primary batteries.
