Initializing a Flip-Flop on Power-up

Twice as expensive and it only makes two cups at a time? Well, forget
that.

When I'm alone here, I don't want to make a pot of coffee. So I use
the Senseo to make one cup. Fresh coffee everytime. A pot of coffee
tastes horrible after 45 minutes, even 30 minutes is only just acceptable.
So I pay more, but I also get more ;)

Hello Jim,
You're talking pushing the PCB design rules. I was talking CHIP.

No, I meant chip. That's where we had to push the envelope the most, to
make these chips small enough. The flex PCB was also very dense, of
course, but the issue there was mostly placement. Every company that
does flip chip bonding told us we are crazy. So, we designed our own
flip chip bonders. That did the trick.

Regards, Joerg

Hello Rich,
That's not _breaking_ the design rules, that's _writing new_ ones! ;-)

That's what IC designers said as well 8-D

When I went to an IC designer for another larger chip like this, a 64
mux chip all on one die and higher voltage, he looked at my simulations
and the schematic and felt it could be done on an automotive process.
Then he saw the maximum dimensions we were planning on and sighed a loud
"oh boy!". But, he pulled it off. "Now don't throw another one of these
at me", he said afterwards.

You assumed all the risk and the process house had no exposure... you
violated their spacing rules. Wanna be my customer ?:)

Yep. Sometimes that's the only way to go. If it hadn't been done there
would be no electronic intravascular ultrasound today, meaning there
would also be no way to locally assess a Doppler kind of blood flow
pattern in a coronary artery. I bet quite a few people wouldn't be alive
if it hadn't been done. No idea how many cases have been successfully
performed so far but it's in the high six digits.

Wanna be my customer ?:)

Actually, I think I'd enjoy that :)

Sometimes if I'm slightly sluggish after arriving home in early
evening, after 12 hours at work, I'll drink a cup or two before I do a
hard cycle exercise for about 3/4-1 hour. This offsets the caffeine -
have no problem sleeping, and wake up feeling like Superman.

I assume that's 3-4 hours before going to sleep? I can't get to sleep
for an hour or two after even moderate exercise. A cup or two of
coffee doesn't seem to matter much one way or the other.

Hello Frank,


I think it is twice as expensive compared with a normal
coffeemaker. That doesn't worry me at all.

Ok, I guess the cartridges or bags or whatever goes into such machines
also cost more per ounce or gram of coffee. But now you are stuck with
whatever selection they offer. With a regular coffee maker you can pick
or even mix you own favorite kind of coffee. Our local stores here in
the small town (pop 15,000) already offer about 20-30 different kinds of
coffee beans. And I like freshly ground coffee. When it's stored already
ground it doesn't taste as good.

Then there is the all-traditional method. Heat water on wood stove or
barbeque, pour into ceramic coffee filter by hand. That feels especially
good during a power outage when all the high-tech neighbors' machines
are useless and we can still enjoy a coffee that's better than in a
fancy coffee shop. With freshly made pancakes and the whole nine yards.
I drink milk and juice also, and cold tap water. We have fantastic
tap water here. ...


Did you ever do a chlorine test on it? Ours tastes ok but it shocked me
when I did the test. Now it's coal-filtered and that does make a
difference in coffee.

There are a few different kinds of pods, but I take the 'dark roast'
kind. I also adjusted the timer/pot inside the Senseo, so that it
give a little bit less water than usual. BTW, there's a PIC inside.
I've also seen a plastic pod-shaped filter thingy, that you can (re)fill
with your own coffee - but that is probably very messy to deal with.

Such occasions call for a shot of Tia Maria in your coffee ;)

Our tap water (at least where I live) has zero chlorine and is as good
or even better than bottled spring water. Filtered by the sand dunes
and a minimal amount of additional processing. They only remove some
of the calcium, add some oxygen I think, and continous testing of course.

Nah, if you are prepared even a longer power outage can leave you
unfazed. You just have to barbeque just about anything that is in the
freezer.

That's great. I am surprised they don't put any chlorine in. I remember
that when I was young you could take a bucket of water from the Rhine
river and develop monochrome Kodak film in it. No chemicals needed, all
courtesy of whatever companies were upstream.

The kind of exercise before bed is sustained 70% max heart rate, which
means mildly fast breathing at 40bpm and slight perspiration level of
effort, for about 3/4 hour. You can go to sleep within next 1/2 hour,
get a real 7-8 hours of sleep, then do a heavy workout no sooner than 1
hour after waking, duration 1 hour, take a 15 minute rejuvenation nap,
and go to work. You're good to go for the next 18 hours with little to
no fatigue. This week I'll not be exercising at all so as to avoid
complications due to a lumbar puncture, so my sleep is not worth #%^&*.

I grind my coffee by hand. I use a kitchen scale to weigh 20 g of French
Roast beans from Peet's. After grinding, I put the ground coffee in one of
those reusable gold filters, and put the filter in one of those deals that
rest right on top of the cup. There's about 4 oz of warm milk in the
bottom of the cup. Then I pour the hot water into it slowly from the
kettle. It's a big cup, so by the time I am done, there is probably 10 oz
or more of coffee sitting mostly on top of the warm milk. The coffee in
the top of the cup is almost black.

I tried paper filters, but they don't let enough sediment get through. I
love to swirl the last few ounces of milk and sediment and drink it in one
big gulp before the sediment can fall back down to the bottom. The paper
filters deprive me of this pleasure.

On weekdays, I usually don't have time to make coffee, so I just buy a
latte somewhere on the way to work.

I can't stand to drink coffee that is not absolutely fresh, although I do
drink a cup or two of the coffee we have at work, typically after it has
been sitting on the burner for an undetermined, but long, period.
Did you ever do a chlorine test on it? Ours tastes ok but it shocked me
when I did the test. Now it's coal-filtered and that does make a

If you can taste the chlorine in the coffee, the coffee is too weak. ;-)

Hey, I'm surprised that you don't have a well. I thought you lived out in
the country somewhere in southern California.

Joerg, you've heard that they've invented a more sensitive condom?

It stays awake for an hour afterwards and talks to her and lets me roll over
and go to sleep.
