Just as a matter of interest. That people didn't live much past 35 is a common misconception.  The average life expectancy of 35 is a result of a very high infant mortality rate and does not mean that people did not live to be 90 (or that people did not previously die slowly and painfully).

Oh sure, I know that. Bill regularly conflates longevity, life
expectancy, and medical care quality as a way of promoting socialized
medicine.

In the old days you'd get a hang nail, it got infected, and you were
dead. Antibiotics and sanitation by far are responsible for most of
our longer life expectancy today. The next levels of life expectancy
come from not joining a gang, driving carefully, and not eating
yourself to death (common in America).

We cure a bunch of things that used to be fatal, like cancers, but I'm
not sure that adds much LE. America does that much better, for
example, but the deficit from overeating outweighs it.

No useful specs.
That is normal with many Asian suppliers, got to get used to it and test
a lot for yourself. You can sometimes obtain additional data from them
but sometimes you'd have to be married to the CEO's cousin's daughter or
something like that.
"Test a lot?" What does that tell me? It went against my grain to use a
green LED (GaN) at 3.3V. "Because one works..." Well, at least if the next
lot doesn't work we'll know.
I didn't mean a lot as in production lot, but as in "a lot of testing"
Meaning some of the properties have to be measure. In some designs that
is the only way to succeed because there are no parts that can
"formally" do what you need them to do.
http://www.rohm.com/products/discrete/transistor/complex/#03
"Very small package with two transistors."
All those aren't fast though.
Me? I don't need fast. ;-)
Lucky you
Almost all my stuff is RF nowadays.
We buy modules for all that stuff. I wouldn't attempt it with the shoestring
capital budget we're on (we're down a scope and it doesn't appear that they're
going to even replace it).
A scope? That's scary. I hope that doesn't mean any bad news. You can
nowadays get a lotta scope for $1-2k.
Or a Rigol, for $350.
That may be bit skimpy. I often find myself debugging and finding things
on the digital side, where everyone was 110% sure it couldn't possibly
be a software issue. That's mostly SPI and other serial buses where 2ch
won't really work. Also, I found that 100MHz BW ain't enough. Glitches
in systems where a 8051 screams along at 80MHz or so are specterally
above that.
That's been my point when management (and the other engineer) suggest that
100MHz is enough. Gotta have at least 3X, 5x is better.
No need for 3x or 5x here. I have a 200MHz BW scope with 1GSPS realtime,
cost me about $1800 including tax. If things get any faster then I can
usually make them repetitive, at least on a temporary basis, and fire up
the old HP. That only has a 40MHz converter but a very good one and its
BW is 1GHz.
It's just so weird to see the words "8051 screams along" run together like
that. ;-)
Like this
http://www.youtube.com/watch?v=pBD0YpdRf4Y
I am not a gigital guy but AFAIK there aren't too many other uCs that
you can clock at 100MHz.
We use an NXP ARM LPC1754, and it can clock at 100 MHz. Since it's a
register-rich 32-bit RISC thing, it really screams. We buy them
programmed with our code and laser marked from Arrow for $4.75 each.
you can even get the lpc1759 that will run at 120MHz, but it has 4x
the
memory so it will cost a bit more

it is impressive how much processing power you can get in a single
chip
that really only need a 3.3V supply and sometimes an xtal

We're also using LPC3250s, which clock at 270 MHz or some such, around
$8.
they need external memory that gets a bit more complicated

-Lasse

This afternoon we first applied power to a laser controller that uses
a 3250. The test LEDs (upper left) came up funny because they are
connected to output-only ports (no tri-state) and various port bits
power up high or low! Turns out that's in the fine print somewhere.

ftp://jjlarkin.lmi.net/T940_first_board.jpg

The good news is that we loaded a never-before-run DRAM test, and it
(and the DRAM!!! and all the power supplies!!!) works!!!

This is only 6 layers; I don't know how The Brat managed to pull that
off.

That is very good for a first layout. Give her a raise

That occurred to me, apparently some minutes after it occurred to you!

If he has access to both sides of his load, he can bridge-drive it
from some arbitrary number of octal buffers. That should be very
clean. And cheap; Joerg like cheap!

Yeah, unfortunately the other side is unaccessible. Now a 1:2
transformer, that might be the ticket. Maybe I'll figure one out.

If he can do a 2:1 or 3:1 transformer then he might be able to drive
it all off one array, saving him the need for balanced anti-phase
drive signals for a bridge.

Slower dv/dt that way, so maybe use something faster than ACT...

1:1 trannies are really easy to make. Just one piece of micro-coax, a
few turns on a ferrite toroid. The braid is the primary and the inner
is the secondary. Very fast.

One wee problem is that, while DC can be piped around it, transformers
with ratios other than 1:1, 1:4 and so on are very diffuclt to make
wideband.

And that's exactly the problem. Dealers want to make money so they mix a
teaser drug into soft drugs and ... kaboom, brain's almost fried. This
is how a guy whom I knew died. Several others are permanently mentally
disabled, and very seriously.

But Joerg, that isn't the only side. There are so many
others, as well. Just to add some balance, I'll talk about a
few.

The near trillion dollar a year business bribes everyone in
our gov't systems. Corrupt police, corrupt judges, corrupt
politicians, and a great deal of violence as well because
there is no court system that can be used to adjudicate
disputes. (So folks take 'justice' into their own hands, as
there is no other option except walking away.)

The destruction caused to society is profound and spreads
across every part of it. Our own US gov't was involved in
transporting cocaine into the US under the Reagan/Bush
administration as part of a larger plan to circumvent the
Boland amendments. It was horrible what that did in our
society. (If you need some names to look up, check up on
Donald Gregg, the senior advisor to G Bush sr and a daily
advisor to him; and Felix Rodriguez who met regularly with
Donald ... as just a very tiny sampling.)

We _must_ be able to trust our police and judicial system, if
it is to function well for all of us. You don't mention any
of this. And it is a cost that is both personal to those who
are dealt injustices by it as well as general.

Trust, yes, but one must remain watchful. I had an experience a few days
ago that was disappointing. Called 911 because someone left two large
dogs in a small car in the full sun. When the driver didn't return after
10mins and the dogs started to obviously suffer I called. The deputy
came and qizzed me. How I could come to the conclusion that they suffer
and so on. WHAT?

And there is more. My daughter suffers from grand mal
seizures. Just about had one today and I spent a large part
of it holding her and helping her get through the risk. We
have tried nearly every viable drug for controlling these
seizures over the last 14 years. Many of them have serious
side effects, such as significant enhancement of tooth and
gum decay, listlessness and lack of life during the day,
liver and kidney damage that can be measured by the year,
profound and difficult personality changes, and other medical
risks. Some years ago, our neurologist decided to have us
try marijuana under the OMMP program and we measured the
impact (we keep daily records.) It was promising. We went
off of it, while trying still other drugs for a few years
since. We've only just started returning to marijuana
perhaps 6 months ago under the OMMP program in Oregon, when
her seizures increased to a rate of one every 6-8 days. Over
the last six months, we've experienced three seizure events.
It was a sudden and dramatic reduction and we are as certain
as one can be under the circumstances.

I cannot tell you how important this is in our lives. It
affects everything about our ability to cope and deal with
her seizures. And her personality has bloomed, as well. She
is drawing pictures every day, attempting to talk more with
us, and able to cope much better with the sounds that she is
so sensitive to during each day (bird calls outside can drive
her nuts, but do so much less now, for example.)

Time will tell us more. We are doing this entirely under the
control of both our neurologist and our general practitioner
-- the first we've been working with since 2003 (8 years now)
and the 2nd has been her doctor for almost 20 years. They
know our situation as well as any professionals may. And
they were taking care of her and trying to help us for many
years before we decided to try this, so it's not only our own
judgments here. It's the opinion of well trained
professionals who have had long experience with our
particular case and know where we have been over the years.

You may not appreciate just what this means. Our daughter
broke six teeth in one event over the bathtub. Just one
event. There were many others where she broke more in
differing situations. She broke both her radius and ulna in
another seizure. Clean through. She trapped an electric
heater between her legs in another and in the few seconds it
took for one of us to run down the hallway to get to her
room, she suffered 3rd degree burns to her inner thighs. She
will eventually die in one of these.. perhaps by falling
through some plate glass.. perhaps by falling at the top of
some stairway in some random moment we aren't immediately
present and can grab her. Something will get her. And the
more frequent the seizures, the more potential for that event
happening sooner than later.

It makes a HUGE difference. And so far, it is the very best
impact we've seen on her seizures. Others may have other
experiences. But in her case, there is no longer much
question that we are unaware of anything close to as good.
And we've been through every appropriate drug on the list
(large chart, large list, some not appropriate, but all
appropriate ones tried by now.)

There _are_ medical uses. But we are at risk every single
day because the Fed's consider it a crime. We are at risk
every day because someone may decide to invade our home
because of the black market. We are at risk for no good
reason. Our doctors are monitoring our use, we keep daily
records, and our federal system refuses to lower the
classification so that properly compounded and controlled
quantities can be prepared and used under medical
supervision.

There are many sides. You don't have to believe or agree
with any one part of it, but I think you need to understand
that there is much damage done by an industry that is illegal
and due to the huge moneys involved extremely corrupting at a
variety of levels. (There is a set of Congressional
testimony available in the Congressional Record, if you like,
that would scare most people because of how pervasive and
sweeping these effects were found to be during the Kerry
'drug hearings' in the late 1980's.) And it is very personal
to me, as well, as it places my family at personal and
continual risk and prevents my doctors from doing their job
as they should be able to do it.

It means something to me. One day, some time back, my wife
and I got to do one of the few 'dates' (maybe two a year, if
we are lucky?) where we got to go together to the grocery
store for some shopping and holding hands together. My
oldest son stayed back to watch Athena. When we arrived back
home, gone no longer than an hour, Becky wouldn't get out of
the car. She just sat there. I said, "What's up?" She
said, "You go in, see if she is still alive, and let me
know."

That's what our life is like, Joerg. And we now have
something that materially impacts that in our lives. You
know me. I'm telling you. You need to understand the
difference this makes in OUR lives, as well. Perhaps you
need to hear a different story from someone else you know so
that you can balance this a little better?

It's not just a little bit personal, Joerg. Just so you
know.

Jon, I don't have anything against a (very carefully) prescribed medical
use. And I am sure it is a very valuable medicine in your daughter's
case because only parents can really tell what works and what doesn't.
There are lots of other drugs that are regularly used as hallucinogens
illegally but have very legitimate med uses, such as Oxycontin. If a
medical doctor and not some self-declared "practitioner" prescribes it,
by all means. What I do not like and am squarely against is this: There
was a pot fest somewhere near here. TV came, interviews. "Oh, the fenced
in area is so people can get high" ... "But you need a medical
permission to get in there, right?" ... "Oh, yeah, if you don't have one
yet you go over there, talk to the people and then get it. Doesn't take
long". That makes me sick.

But what really made me sad was what I saw while living in the
Netherlands. You, promising people. Then one day I met them again and
their brain was fried, permanently. Some could only babble, some could
not talk at all anymore.

Normandy, rural area. In NL I lived in a rural and what I saw there sure
was enough for me. Also, I spent a lot of time in Belgium and saw much
less druggies who were eternally zonked out. In Scotland, none.

http://en.wikipedia.org/wiki/Drug_policy_of_the_Netherlands
Quote "The drug policy of the Netherlands is marked by its
distinguishing between so called "soft" and "hard drugs"."

And that's exactly the problem. Dealers want to make money so they mix a
teaser drug into soft drugs and ... kaboom, brain's almost fried. This
is how a guy whom I knew died. Several others are permanently mentally

So legalise the supply of soft drugs, and get it out of the hands of
people who also want to supply hard drugs. Do you find teaser drugs in
your beer or - if you smoke - your tobacco?

Or - come to think of it - your chocolate, your coffee, your tea or
your ginger?

It's too late for drugs. It is the same thing every time with organized
crime. Once some "market" is in their hands they won't let go. Alcohol
never was in their hands in Europe. In the US it was, thanks to the
prohibition, and sure enough it invited organized crime into the country
which then never left.

That's the thing, I never took any drugs nor was I in the scene. But I
saw it every day, in the small town of Vaals in Zuid Limburg. And in
Heerlen. And ...

The woman that wept a lot because her son (whom I knew) died from drugs.
The guy who'd stare through you if you said "goede morgen". The guy in
the space suit who cleaned street gutters all day long although they
were clean. He couldn't talk at all anymore. Should I go on? This was
back then a village of about 5000 people, so families knew each other
quite well.

As a Dutchman, if you really want something to turn your stomach, try
investigating the origins of all those trafficked slave women in the red
light district of Amsterdam. IIRC about 4 out of 5 were trafficked from
Russia and eastern Europe, and they suffer rape and worse, continually,
until they're too sick or too worn out to be worth anything any more.
Well, if you want to see unhappy women you should go to the red-light
district. However, your information is a bit outdated. Many laws and
regulations have been put in effect to minimize the possibility of
human trafficking and enslavement. It is very difficult to get a
permit to open a sex-club (aka massage salon). Even the well known
Yab-Yum has been closed down by the local authorities because there
where rumours the owners had ties with the criminal circuit.
Outdated? From what I have heard they have discovered a new source of
"revenue" and are now taxing the redlight districts:
http://www.breitbart.com/article.php?id=D9KMSBS81&show_article=1
it's a job/business, why shouldn't they pay tax like everyone else?
So we look the other way when the question regarding the residency
permit comes up?
Being a "sex worker" is a legitimate job in the Netherlands, and
people coming from those eastern European countries that are now part
of the recently extended European Union don't need any kind of
residency permit anyway.
You still need the Vergunning to Verblijf, just like I did. That's what
a Dutch couple that was here three weeks ago told me. They know that for
a fact because one of them is from the EU but not a Dutch citizen.

I doubt if you'd need it now. My wife and I both needed them in 1993
because we are Australian citizens, but one of my wife's English
colleagues who moved to the Netherlands at the same time didn't have
to bother.

Then you may have been in the country illegally

Yeah, let's leave it at that. To me abortion is killing a human being,
plain and simple. Nobody can tell me "the child would have no future",
because it would have.

Abortion is a service? You've got to be kidding. To me that's murder for

Just out of personal interest: I guess you are against the death

Yes.

It's still better to not saturate them. Even a simple b-c schottky

74AC is too slow for my case. How did you keep it out of saturation? The
old Schottky Baker clamp usually doesn't work on those. A two-diode
Baker makes it all sluggish, too much total inductance in the drive.
A 74ACT octal buffer makes a damned fine high-speed output driver or
fet gate driver. Use 4 or better all 8 sections in parallel.

Can it rival the NL37 series? The advantage would be that those come in
octals. In the old days I have sometimes soldered several on top of each
other but only in experiments. I know that was naughty but it did drive
the big pulser (the super expensive lab grade driver box had croaked).
It was 74AC though.
They are almost as fast as NL37s, sub-ns, but have the advantage that
they are "ttl" compatible. If you power an NL from, say, 6.5 volts and
drive the input from 3.3 or even 5 volt logic, they can really get
hot.

Plus, you get 8 in a can.

Ok, that almost sounds like a deal. Being a bit slower can be made up by
more drive gusto. Eight means more amps than three. Just like the old
muscle car wisdom, cubic inches cannot be replaced by anthing, except by
more cubic-inches


Hey Joerg,

Can you apply steps to opposite sides of the capacitive load? +6 step
on one side, -6 on the other. Make those from a mess of ACTs or Tiny
Logic chips. Maybe a little inductive peaking to spice things up.

Double the voltage! Cheap!

I sure wish, but can't get at the other side of the capacitance. If
really, really needed and I can't make any filter-style peaker work well
enough I'd have to roach it all into a circuit with either boostrapped
of artificially split supplies, to squeeze out more amplitude. That will
be the ultimate layout challenge because it all must be very small. Now
if I could design this into an IC, well, then ...

I did that waayyy back. It's pretty impressive. One of the last

Oh, just do that into a transformer then and you're done. 12v, hard,
fast, galvanically isolated, and cheap. A custom transformer would
allow voltage step-up, if you wanted.
1:1 transmission-line transformer. Easy. Zere are treeks to make ze
pulse tops really, really flat.

But ven you vant 2:1 dere iss more difficoolt.

We've done 2:1, and it is a minor nuisance. Bridge driving ze 1:1 is
better, economically.

Hand-made magnetics are usually met with some disgust in design reviews.
"You mean, Mini Circuits doesn't make it?" ... "No".

But man's gotta do what man's gotta do

If he can do a 2:1 or 3:1 transformer then he might be able to drive
it all off one array, saving him the need for balanced anti-phase
drive signals for a bridge.

Slower dv/dt that way, so maybe use something faster than ACT...

--James

1:1 trannies are really easy to make. Just one piece of micro-coax, a
few turns on a ferrite toroid. The braid is the primary and the inner
is the secondary. Very fast.

Right. But try to buy one off the shelf ...

One wee problem is that, while DC can be piped around it, transformers
with ratios other than 1:1, 1:4 and so on are very diffuclt to make
wideband.

A 2:1 transmission line transformer is fairly easy. Two hanks of
micro-coax on a toroid. Braids in parallel make the primary, inners in
series are the secondary. Risetime is still way below 1 ns.

One other cute trick is a pulse inverter. One winding on a toroid, but
the inner and outer swap halfway through.

No. That was just carelessness.


How does that justify killing the unborn?

1980-1986. It was the same in other towns. I also worked up there near
