Actually now he is a bigger threat.


Remember: the intelligence agencies from ALL OVER THE WORLD were
giving input that Saddam was planning this, planning that, etc. We
really need a stronger, more effective CIA (fix the problems -- whatever
is needed), but alas, Clinton worked to weaken the CIA... The long,
horrible, disarming history since the middle 1970's is (partially) yet
another disgusting legacy item from left wing over-reaction against Nixon's
abuses. Geesh, stealing/destroying information from opposition political
headquarters is now a regular Democrat activity... Over the last few
weeks, there have been serious and obviously orchestrated abuses by
the Dems against anyone that they appear to hate. The organization
does show an 'Usama' type situation in the Democrat party, where there
is obviously some strategic planning happening at the highest levels,
but the individual implementations have been incompetent WRT public
relations. Too bad that the 'public' that the Dems appeal to do tend
NOT to be informed about these ongoing Democrat abuses. The organization
is too strong to be attributed to hooliganism, even though it is more
likely that the Dems be like that -- but it is clear that there have
been attacks that were orchestrated at the highest levels, including
even the go-ahead being given by Kerry himself.

Depending upon Putin and even the UK for intelligence info shows the
sad state of affairs in US intelligence. Even if there were a few
data items that might have claimed that Saddam wasn't a threat, the
whole problem is: "WHICH INTELLIGENCE ITEM IS CORRECT, WHICH INTELLIGENCE
ITEM IS INCORRECT." In hindsight, the decision is much easier.

In all cases, it is clear that both the GOPers and Dems believed that
Saddam was a threat (in one way or another), and given that -- there is
no really serious political fault EXCEPT for the longer term, strategic
weakening of the CIA (and other intelligence agencies.)

You don't know what you are talking about, as usual. I'd like to see
some non-partisan evidence for even ONE of the allegations you make
here, which are:

a) Clinton worked to weaken the CIA
b) Democrats are stealing/destroying information.
c) This alleged stealing is orchestrated by highest levels in the party.
d) Democrats tend not to pay attention to the news.
e) Kerry gave his personal go-ahead to steal information.
f) There were clear indications that Saddam wanted to attack the US

None of these statements are true, as far as I know. Please try to prove
ANY of them. I'm waiting.

You sound surprised. ;-)

Well, it's obvious that Moore is a partisan. He states as much. The
movie Farenheit 9/11 is a politial polemic, a visual op-ed. It's
opinion. Thus, there should be SOMETHING they can yap about, some
obvious lie that Moore is trying to use to support his point.

However, according to Moore, Farenheit 9/11 has been fact checked for
accuracy. There are scenes where he points out possibilities without
proof, but he never actually makes the claim, he just points at it and
lets his viewers come to the unsupported conclusion. That's what OpEd
does, it tries to frame things for us. However, to be 'intellectually
honest', it has to use real facts to do this. That's where Coulter and
Moore diverge. They both have their opinions to support, but Coulter
makes stuff up for this, and Moore doesn't.

Just saying Moore is a liar because of his opinions is irresponsible,
and shows a lack of judgement, and indeed shows the sort of inability to
discriminate fact from opinion that the right wing political pundits,
and perhaps even the Bush administration, depend on for their survival.

Sorry I forgot, I am trying to obtain 2-4ms bi-phasic square pulses from

resident expert on this topic is
on vacation at the moment). Also, I saw some of the other suggestions
with supply voltages around 40-55V, I dont think that I will be able to
obtain sources above +-15V for the supply.


You also stipulated that the muscle be grounded, and that you might need
to drive 10 mA into 2k. This is impossible, I believe, since 10mA * 2k =
20 Volts.

snap

Anyway, If you are only going to have +/- 15 Volt supplies, and you only
need 10 mA, I would think you could work something out with op-amps.

For example, I still think you could use a current sensing resistor with a
difference amplifier across it, and take the output of the difference
amplifier back to the driving op-amp. You may need to use rail-to-rail IO
op-amps all around.

I don't know, maybe the offset voltages and stuff would add up and kill
you. I'm not going to do the analysis. ;-)

years ago I built a circuit that does exactly this, for a
(+/-10V)/(+/-20mA) analogue output circuit for a drive. The basic
circuit design was my techs, I just worked out the equations and
calculated the relevant component values. The circuit did work, in much
the way you suggest. A diff-amp sensed the drop across a small series
resistor, feeding back to the input of the voltage gain stage and
thereby controlling current - a current-limited voltage source. There
was a bit of stuff in there to switch between V & I out (actually that
was a real pain, we needed the low Vf of a schottky, but the leakage was
a huge problem and we were too tight to buy a good schottky, mostly
because having a single smt part is not cost-effective)

We built quite a few of these (5,000 or so), but what we found in
practice was the diff amp made a great resistor mismatch detector. Using
1% parts throughout, our overall tolerance ended up about +/- 7% IIRC.
We didnt want to throw away so much dynamic range for s/w cal, so we
re-designed the circuit as a voltage-limited current source (the
modified howland circuit) ie the topological dual of the suggested
circuit. The modified howland circuit is a piece of piss to analyse, and
worked a treat - tolerance dropped to around +/- 3% which pleased both
the s/w and production people immensely.

Cheers
Terry

But, just to be more concrete, you could have an op-amp driving the
load through a 10-Ohm current sensing resistor. Across this resistor
would be a difference amplifier with a gain of, say, 10, whose output is
then fed back to the inverting input of the driving op-amp.

So, when you apply 1 V to the op-amp, the output current would increase
until you had 0.1 V across the CS resistor, which would imply 10 mA into
the load. So the slope is 10 mA per volt, but it could be reduced to
whatever you want with a voltage divider. Maybe you need to offset it,
too. It's not clear what the spec is from your description. But that
should be easy with one more op-amp.

At the maximum current of 10 mA, you would only be dropping 0.01 * 10 =
0.1 Volts in the current sense resistor. You could probably make it even
bigger. Maybe 49.9 Ohms.

Anyway, good luck!

Answer the question: do you REALLY think that EVERYTHING Kerry has

What statements in particular do you have in mind? A victory for Kerry
will be a victory for bipartisan government restoration to mend the
damage done by the incompetent idiot Bush and his ever shrinking circle
of clueless ideologues. A vote for the GOP is a vote for a criminally
incompetent autocrat, and a vote for Kerry is a vote for an executive
bipartisan coalition. Only a simple idiot would think the race boils
down to two personalities. The word coming out of DC is not good- this
Bush character is becoming more and more irrational and pushing what few
ideologues who remain out of his inner circle of nutcase prayer session
idiots. The criminally incompetent Bush is waiting until after the
elections to ask for another trillion dollar increase in national debt (
his second trillion dollar increase BTW) and $70B *more* for Iraq on top
of the $25 already budgeted for this FY- which Pentagon projects to be
bare minimum- bringing the Iraq total to $225B, and an additional 40,000
troops for the bogus elections there. Army recruitment is dropping like
a rock-already at 30% shortfalls, and servicemen are successfully suing
against the illegality of the indefinite extensions of service due to
fact that no war has been formally declared. It takes quite a monumental
incompetent to bring America to its knees but Bush has done
it-everything is coming apart at the center- there will be massive
government shutdowns across the board and possibly default. Congress
should exercise their authority and shut the whole damned thing down and
institute immediate impeachment proceedings to get rid of Bush ASAP. You
watch and see, something like this WILL happen. The US is a system of
checks and balances, the President is NOT a dictator, and the idiot will
stress that architecture to something unprecedented in American history-
Bush WILL be ejected one way or the other. The most orderly process is
simply to vote him out and then lame duck him into oblivion. This has
nothing to do with spin, this has nothing to do with politics, this has
everything to do with the most incredibly incompetent fraud to ever gain
control of the White House.

Anyone doing serious circuit design of any kind should have a scope.
For amateur radio work $3000 will buy you a _lot_ of scope. I'd
recommend that you get something with around 100MHz bandwidth and two
traces. If you look at the B&K Precision stuff in the $700 to $1000
range you should find something useful. Of course, a 4-channel 200MHz
Tek or Agilent scope with a color display wouldn't be bad, but it's more
than you probably need.

My personal scope is an Agilent mixed signal scope (two channels of
analog plus a 16-channel logic analyzer), with a 100MHz bandwidth. For
what I do it's perfect; if I should need to use a $30000 LeCroy O-scope
I'll lease it.

Hi Tim,

On a side note, something that blew me and others away: A visitor from
Europe had problems adjusting his analog 'atomic' wrist watch. Their
transmitter works on 77.5KHz so the clock didn't adjust to PST and since
he forgot the manual we didn't see how to do that manually.



Typical Euro-doofus.


Well, I don't know which was first or is better, WWVB or DCF77.

Sometimes our stuff wins, sometimes theirs. All I know is that the
European version is not so limited to sync at night but that won't make
much of a difference in real applications.

Then while
visiting Sequioa National Park it happened. Suddenly the hands started
to move and the watch accurately set itself to PST.



????


That was exactly my reaction ;-)

When he came back
here it matched our WWVB clock to the second. Someone there must be
running a site similar to DCF77, the time transmitter in Germany.



But broadcasting a time that's incorrect by 7 or 8 hours?????
(difference
between UTC and PST/PDT).

Unlicensed operations are allowed on longwave frequencies, but they're
limited to one watt and the frequency range is 160kHz to 190kHz
("lowfers").


But this could only work at 77.5KHz since these watches have crystal

filter of just a few ten Hertz bandwidth.

It seems more likely to me that previous tinkering with the watch
finally "caught up" with it, maybe after it convinced itself there
was no usable signal on 77.5kHz for some extended period. All a
guess,
of course: How someone could knowing how to set an analog watch is
still the biggest mystery to me.


That is possible but it was almost a week after that tinkering. The

challenge with some of these watches is that they have stop watch
functions, lap timers and what not so it is next to impossible to figure
out more intricate stuff. Such as how overriding the 'atomic' feature is
done without a manual. Hold this button for 2 secs, press that other one
twice, push a 3rd one within 2 secs, then push #1 to advance the time
zone. I've got a non-atomic watch that has four stepper motors in there
and a gazillion functions. The only one I know is how to set time zones
which is all I need, for the others I'd have to read up.
