Mine's actually in full working order (although I don't use it; just

quite unprecedented.

I have read it. The suggestion was really a joke --- right?

It happens everytime a Republican is in office and the DemocRats can't see
anyway to dislodge him. In fact, I've seen it several times.

Not really- it has been acknowledged by foreign policy experts of all
political persuasions that the ideal President to handle this situation
would be Richard M. Nixon, if we had to choose from Presidents we know
that is.

Sorry. I thought you would understand. Since that is not the case I'll go
back into the lurker mode.

Gee, this simply isn't fair as it fails to properly acknowledge Bush for
finding and bringing to justice 75% of Al Qaida members. I heard Bush say this
over 6 times now so it must be true.

The people who accept that claim apparently do not know what the word
'ideology' means- Bush administration advisors have certainly used the
word often enough- but Bush doesn't seem to have 'grapsed' it- it's just
not part of the vocabulary of his 'idiotogy': there are bad guys, you
kill them, and they are gone. I also enjoyed Bush's "dynamic on the
ground? dynamic on the ground? what does that *meeeeee...ean?" during
the debates. Maybe Bush should be put on the ground in Iraq- he seems
quite brave when shooting his mouth off from 6,000 miles away about
standing "in solidarity" with a hostage about to be beheaded- that's the
most ridiculous thing I have ever heard in my life.

Sounds like you, fredrook.

You have been reduced to a minor annoyance because the dam of Bush
deception has broken and the truth is pouring through. To quote your
brain-damaged Bush "it's just that simple"- it's real simple, US foreign
policy has been transformed into a war policy from which thousands of
corporate backers of the RNC are profiting on an enormous scale, health
policy has been transformed into a lucrative business for the
pharmaceutical and insurance industry, environmental policy has been
transformed into a 'wish' with no substance. Here are some recent
scandals just breaking: a senior EPA scientific has just blown the
whistle to Congress with an 18-page report detailing the blatant fraud
behind the EPA decision to NOT regulate hydraulic fracturing technology
under the clean water act, a decision made by a policy board with
several Halliburton employees as members- they went a bit too far by
"dismissing" ( a word we here time and time and time again about Bush)
the scientific field reports; another major whistle blowing scandal
erupting regarding more fraud within the US Agency for International
Development (USAID) and more lawbreaking where that agency specifically
took action to prevent any form of US inspection of foreign recipients
violating many provisions of environmental codes overseas despite strong
evidence that such violations are occurring. It is United States law
that such inspections be conducted and that such violations be corrected
and that financial assistance be revoked for non-compliance- THIS IS THE
LAW, once again Bush political appointees break the law to the advantage
of business profits for American corporate concerns. I wonder do the
American people know that their tax dollars are going to underwrite
loans, many of which have no chance of being repaid, to exploit natural
resources, destabilize political systems, secure the position of corrupt
dictatorships, and generally make the world a more dangerous and filthy
place, all to benefit investment interests of the few? And all of this
occurring in clear violation of the purpose of US law?

Hi,

I would like to use software for p2p file sharing. However, my experience

mistake of using Kazaa, through which I downloaded "Limewire". This turned
out to be one of the biggest mistakes of my life.....right up there with my

downloaded to my machine faster than my antivirus software could eradicate
them. What a fiasco. I then tried KazaaGold, which did not have the spyware
but again, I was unable to download any of the programs that it supposedly
found.

There must be some decent file sharing software out there. Please send some
recommendations.

I want to implement a simple A/D conversion by PC sound card

could be (if you can record music on pc, why not!)

What is the limit/problem in hardware?

max usable frequency response 20Hz-20KHz /around 95dB noise signal
ratio max for cheaper models like mine Ensonic AudioPci128 .... on
line input (150mV/47k); conversion 16-bit, 44,1kHz sampling ...

If you use the mic input it prob. has a dc voltage on it to power an electret
mic, so line in is a better choice. Either way the input with be ac coupled by
a series cap on the card.

Mic input is Mono & in the midle ring on the stereo 3mm jack is that
phantom power; when used an ordinary mono jack, it shorts that, so on
the hot (input) you do not have any DC current!

not sure for line in ... (for Mic in for sure!)

There are
some scope programs for PC's that use the sound card you should find one and
check it out to see the limits of this input.

on mine there is at 19kHz -3dB drop which drastically increases
reaching frequencies above 20kHz; on the other hand there at low end
is same with drop @ 25Hz, but drop increases much much slower & you
can handle 10Hz @ -10dB drop & becomes unuseable lower than 5Hz!

Here is a link to a free sound card scope program on on the net,
I never used it

http://polly.phys.msu.su/~zeld/oscill.html

this I regularly use to make snapshots for my site´s electronics
articles .... for pics there I used for cards input only a resistors
voltage divider (trimmer pot.) ...

since I have an audio Led VU meter connected to my audio card & is
calibrated (has worse frequency ratio than the audio card), I could
approx. calculate signal drop at frequencies I stated for that audio
card...

Hope I helped ...

I agree, M$ do not have full control of the operating system.

M$ is the operating system! The bios is below that, M$ has it's problems
( I'm a unix type) but this example isn't one of them.

Oh, I thought the BIOS was integral. Who else uses it then? (obviously
UNIX don't because you would have said so)

I use the bios to boot IBM's Dos2000. Works fine.

This is the rub: If you make something beautiful on the outside then
it is more likely beautiful inside. M$ don't give a damn e.g. the Caps

(three) of the most often used keys.

Caps lock is indispensable, as real programmers code in uppercase.

The OP want 4 states, two of them 'off', and one flashing. While it can be
done with standard logic, using a cap to power the flipflop, I'd go for
a LP2985 regulator with on/off pin, and a 12F629 pic. 6 parts, a cap
for decoupling, a resistor, the regulator an the pic can do the debounce,
has eeprom to store the states, and to do the flashing, and two diodes
to route the switch to the input and regulator. Oh, well maybe an
extra resistor. 8 parts.

I have an led that I'd like to power with 4 'D' batteries. The first
time that I push the button, I'd like the LED to stay on. The second
time that I push the button the LED will go off. The Flip-flop circuit
will lose power too. The next time I push the button, I'd like the LED
to flash, say 3 times/second. 4th Push, off again. Circuit loses power
again. Goto first push.

Should I just step away from the soldering iron and get some fresh
air?

you could go for the mechanical aproach, each push of the button pushes a
shaft round 90' with a pawl/ratchet mechanism.
cams on each end of the shaft operate contacts as needed. you can get push
buton switches wich have the same mechanism but only 2 positions.

Hi Chris,

Ok, how about this low-tech solution: A sizeable automotive relay. Wrong
polarity - no turn on. It could even light an LED, telling the user that
it would be nice to swap the leads A few hundred amps over a relay is no
big deal and they aren't even that voluminous. It should beat the
Schottky in terms of cost.


Yeah that's been done. ASP in Sweden used that solution. Problem is the no load
current draw of the inverter goes from 0.1 amps in idle mode to 0.7 amps.
Messes up the marketing.


For minimum no-load draw there would have to be a small "bridge". Either

tiny second relay or electronics. This would allow the idle mode stuff
in the inverter to run but since that won't need more than a couple
hundred mA it would be very easy to protect from wrong polarity. Then
when the load is sensed the large relay would close. But only if the
polarity is correct.

Actually with a large relay you could drive the 0.1A quiescent to much
lower levels. If there was a tiny extra PWM circuit the whole big
converter could be off until a load is detected.

I have done that in other applications where loads needed to be sensed
and no user interaction such as flipping a switch was desired. There was
a very small sense portion that was always active but the whole power
path was off until all conditions were met. Sometimes I had to stay in
the microamp range for quiescent.

The two sides have to meet somewhere in the middle. Then there needs to
be some education in the advertising material, plus other publicity.
That's how Honda or Toyota got to command a much higher price for a
sedan than some other brands. People realized that you do get what you
pay for, that there are no free lunches.




Yeah one day the same might happen in the inverter market.


I believe this, along with the same trend for the panels, is a

requirement to get the solar generation market started. Else it will
remain near dormant as it is today. Right now it is as if someone were
to say, hey, buy this hybrid car at $30k. Once we have sold 10,000 units
we'd be able to drop the price to $20k so it can be a hit. Won't work.
Got to take some market risks here.

My bad week at the airport:

On the trip out, I was "selected" for the full treatment: metal-detector
wand, full-body frisk (not, unfortunately, by the young lady inspector
present) and shoes placed in some sort of detection device.

On the trip back three days later, I left my ticket on a table
(thoughtfully provided so travellers can get all their papers and
belongings in proper
order for inspection) on the wrong side of the security screen. As soon
as I noticed, so did the security people, and they paged me to come back
up
against the stream to get it. A word of advice: don't move upstream. I
was physically barred from doing so by a civilian security agent, and
threatened by an armed National Guardsman for the offense of placing my
briefcase on the floor and walking the dozen or so feet back upstream to
the point where I was stopped.

My travelling companion, an Anapolis graduate and Navy Reserve Commander,
was highly amused. I was not.

The overall irony is that the purpose of the trip was to visit a vendor
who was assisting us in the design of a device to detect (real) terrorist
weapons.



Well, at least you didn't spend 16 years in a forced-labor camp. Or
have to sleep in the airport for six days waiting for a plane to be
available, because you can't afford the bribes. Both of which happen
to people who have *real* problems.

Well, just wait. If the neonazis get their way, nobody will go anywhere
without proper papers, clearance, inspection, search, whatever the hell
the nazis want to do.

Unless they're stopped, of course. Don't be fooled by the fact that the
US used to be the land of the Free - this is where the nazis have taken
up residence, except for the handful or so that are running Israel. Can't
