Where are all the ESR meters?

Win, thank you for your concern. They are treating symptoms, not the
real problem. Thanks to Congress the VA is not allowed to treat it.

It's not just VA. Medicare doesn't cover dental either. My wife had
over $12K of dental surgery last year due to (what you seem to have) a
tooth infection that got into the jawbone.

no, I assumed you werent stupid enough to actually do that, and would of
course include some R, as John D. pointed out. Merely illustrating how
to move the switch out of the measurement path, to achieve the same
objective.


I'm not. Did you also expect all the lurkers out there to
understand, as well? I've seen people stupid enough to wire a power
switch across a device to turn it off by shorting it out, then
complaining that they were being sold defective power transformers,
because they kept burning them up.

At least put a smiley with bad ideas like that to give them a clue.
I've smelled enough burnt insulation from people who don't grasp the
basics.

OK, I'll stand while these guys dance around the problem.

John

noting that 10 mA into 1 mohm is 10 microvolts, still pencil-free.

That is still a lot more signal than the noise on the input of an op-
amp or a 100K resistor.

One concern will be inductive coupling in the 4 leads going out to the
DUT; that could easily bash a lot more than 10 uV into the sense
circuit. If it can really do values like a milliohm, the leads will
have to be done right, too.

What's the sinewave source? Are you going to trim the phase of the
drive into the phase-sensitive detector? To get good capacitance
rejection, the phase will have to be spot-on.

If you vary the frequency or use a complex waveform, you can remove a
good estimate of the remaining capacitive component. The cost will be
measurement time.

The VA will do the work if you can pay their price in advance, or
sign papers to allow it to be deducted from your disability pension.
Their rate is higher than some private practices. If I let them do the
work, I would be homeless.

You might consider traveling to a civilized country to get the
work done. I hear they have very good cheap dental treatment in
China, for example.

You try it, and let me know. That is, if you survive.

Golly gee, Ferddie! Just where would I find this support group for
"Congress is practicing medicine, on me?" and has no damn idea what
they're doing?

Why don't YOU abandon usenet and join a support group for "I only
think I'm superior to everything else in the known universe"?

Go to the diabetes group here: http://dailystrength.org/ . Someplace
like that, or similar, would be the more appropriate forum to discuss
your health problems. SED is not the place for it, this is not a support
group, and, speaking of nerve, you're way out of line unloading all your
whining on SED. People get sick, suffer through great pain, and die all
the time. Do you think you're the only one? You have it easy compared to
a lot of people. And then all this garbage about your white trash
neighborhood and everyone laughing and taunting you, sounds like
something you used to do until it came home to bite you. Who the hell do
you think you're fooling? I for one am sick and tired of you victim
types. If you want to discuss electronics then fine, but take your
excess baggage somewhere else.

Your new, recent facade persona didn't last long.

Do you react like this because nobody gives a damn about you, but they do
care about other people? Or are you simply a low-life POS as I suspect?

Right sure I am, and you are well-known to be a limp-wristed old fag
with little to say beyond bitchy little posts containing a few lines of
puke.

Look, I already have a perfectly good ESR meter that I built from a kit
designed by Bob Parker. You can talk to him about it, he is on
aus.electronics and is helpful. I don't feel the need to reinvent the
wheel, especially because it is a good wheel. It would be very hard to
design an ESR meter that would be of more use in practical situations.

A quick look at the schematic and writeup suggests that it can't
untangle ESR from capacitance at low C values. The "good esr versus
capacitance" chart screened on the front confirms.

Besides, this is sci.electronics.design, not sci.electronics.copy.

**** you. You're the biggest whiner on the group, but when you do
it, you call it "Constructive Criticism". You don't even have the balls
to use a real name.

People get sick, suffer through great pain, and die all
the time. Do you think you're the only one? You have it easy compared to
a lot of people.


Now you think that you're qualified to practice medicine? What proof
do you have of my exact condition, and what I'm doing about it?

And then all this garbage about your white trash
neighborhood and everyone laughing and taunting you, sounds like
something you used to do until it came home to bite you.


More of your fucking arrogance? I have never treated anyone that
way. Although I will admit that I have to bow to your extensive
experience of being white trash, and how badly they treat others.

Who the hell do
you think you're fooling? I for one am sick and tired of you victim
types.


Fooling? Bite me, jackass. On second thought, don't.

You're sick and tired of anyone who doesn't kiss your sorry,
opinionated ass. I'm tired of morons who don't know what the hell they
are talking about, trying to give me bad advice. My doctor thinks I am
coping quite well. I am doing everything by the book do maintain both my
blood sugar and blood pressure. Its people like you who don't give a
shit about anyone else that need the help.



You're like the old bastard who stopped me in a parking lot to give
me hell for wearing prescription surgical stockings, yelling that a REAL
MAN would never were that sissy fag stuff!!!! I told him to **** off,
that they prescribed by my doctor in an attempt to prevent me losing my
legs to diabetes, and that they allowed me to at least get out of bed
and walk. Then I got in his face and told him that if it would help me
walk better, I would buy and wear six inch stilettos. That shut the old
shit up.

Other assholes have tried to run me down in a parking lot, almost
hitting the row of parked cars I was just inches from. They were
looking right at me when they steered the car towards me.

A hispanic moron in a jacked up car with flames painted on the sides
was cursing at me in English, then in Spanish to get the hell out of the
way, because I was walking too slow. I was in a marked crosswalk, in
front of a supermarket.

People constantly intentionally block my path when I'm walking with
the cane. They shove a shopping cart up against the cane and stare at
me.

Quite often someone will se me headed for a cash register and shove
their cart into mine to cut in front of me.

These are not rare instance, just some examples of the way people go
out of their way to inconvenience the disabled.

You don't impress me at all with your arrogance, or your ignorance.
I am not "Playing victim", as you put it. How long would you last
before you were fed up with this shit?

If you want to discuss electronics then fine, but take your
excess baggage somewhere else.


You can go somewhere else, unless you can become THE moderator on this
unmoderated newsgroup, crybaby. I hear that Hell Hilton has your room
ready and waiting for you and your baggage.

fair call.

the stupidest thing I have ever seen was when I was a kid, circa 1975 -
some guy asked my dad to look at his brand new stereo. He had wired
3-pin plugs to each speaker, and plugged them into the mains. oops.
