A good digital oscilloscope?

I think that most of the damage in electronics has already been done, Joerg. We're at a point where the Internet provides incredible opportunities to study and learn even very esoteric bits of engineering that would have been nigh impossible (or at least incredibly time-consuming) even 20 years ago, yet only a tiny fraction of those studying to become EEs take advantage of it as a means to improve the quality of their work beyond what is strictly required of them in a classroom or workplace setting. Hence the primary remaining concern is that those aspiring EEs in China or India or Botswana aren't yet quite as dumbed-down yet as the ones in the US today and hence there'll be fewer and fewer EE jobs here.

That being said, at least when I was in grad school, the Indian and Asian students I knew really weren't that different from the white kids from the U.S. -- most of them were more interested in just getting the sheepskin than in becoming top designers (and apparently some of the female Indian students were planning to use their EE degrees as a means to being able to go back home, work for a couple of years, get married, and drop out of the industry entirely -- the degree was primarily a means to gain access to more desirable guys... whereas for the rather small number of U.S. woman in the program, that didn't seem to be the case...).

Hey, don't cars with automatics generally get a mile or two per gallon better mileage than manuals? ;-)

I thought it had been moved there. Or are they finally moving the spooky= =20 parts stuff there as well?

Nobody would blame you for trying.

o?

By "that", do you mean multiplex or use one ADC per channel?

I prefer functionality over pretty colored knobs, but to each his own...

My photography skills really suck, though. The "labeling" as you call it is quite clear.

The waveforms shown in the display are just the outputs from the probe cal signal. I could connect it to my 8656B generator and get a much nicer trace. I'll put that on my "to do" list.

On the TDS5XX through 7XX, no. Each channel has its own ADC. That may have been true for lower end scopes at the time, but don't quote me on that.

You mean it's calibration voltage is s*it too?

The knobs could have the same color as the traces... If the traces on it have any color at all. A higher resolution screen, we live in 1980x1050 age, decent clearly readable labelling, a not so crappy looking front. Would not want it even for free. Teks suck anyways. That other tek rep posted about a lifetime guarantee. I have heard about 'lifetime guarantee' before, too bad the people are still alive but the company is not... And, imaging you walking into a Tek service centre (well unlikely) in 2039, with one of these, with a defective ADC.. LOL Or any other defective chip.... They must be pretty desperate at Tek to come up with that sort of jive. Give it some time, and the Chinese will have 300$ scopes, sorry 300 Euro (2000 $) scopes... that also sample at 1 G but have more bandwidth. Probably with build in spectrum analyser and logic analyser. Radio, TV, internet, WiFi, Ethernet, and mobile phone plus VOIP as a bonus.

I have some grey hairs, but it is not so bad yet.

Well that counts. I am happy without one of those :-)

Manuals usually get better mileage,but that is changing in -some- models,because of the addition of lockup torque converters and CVTs.

automatics eliminate the need for driver competence.

Note that "unintended accelleration" crashes occur only with automatics.

OK I'm up for it. My real email is in the headers.

You're living in the past... I can't recall any car using a purely "slush" type torque converter for at least 30 years, maybe longer. ...Jim Thompson

Idunno, your fault for not using mainstream software.

Back to Google. Vintage Radio isn't the only place. I don't remember if BAMA has the IO-103.

Yeah, often there is just interest in getting the paper. That was the case for me as well but I knew that I had to acquire all the "real" EE know-how myself because what we learned at academia, well, . So university was just to get the masters degree and designing electronics happened "on the side". However, these days I get quite a few email requests and phone calls from Asia with electronics questions where I ask myself "Did the guy learn anything? Has he heard that there is an Internet? Do they have Art of Electronics over there?"

One can't generalize though because recently I saw a chip design done by a guy in China which truly blew me away. Not just some number-crunch digital chip but serious analog stuff.

As Jim wrote, it's the other way around :-)

They should start teaching the basics again in drivers ed. Like how a car works. In Germany you used to not be able to get a license unless you could explain how an engine worked, and how other stuff such as clutch, gear box or differential worked.

We still learned how to hobble a stalled car off railroad tracks by using starter, clutch and first gear. Of course now they have switches on the clutch that don't let the starter engage unless fully depressed which defeats that extra safety measure.

But they all have to keep sloshing around some of the oil around the shaft lock. There's a reason why even new automatic transmissions run hotter than gear boxes. And warmer = more losses.

Nonsense, it's a stuck accelerator pedal. So shoving in clutch or pushing PRNDL handle into neutral... what's the difference?

If you think fast. In 1957 lost 5 high school classmates who skidded on the ice and got stuck on the track. Got hit by a Norfolk and Western coal train doing about 100MPH :-(

(Thompson's rule: RUN perpendicular to the tracks ;-)

That's really not new. I had a 1950 Nash and a 1953 Hudson Jet that both required full depression of the clutch to activate the starter switch.

Keep deluding yourself... you're fitting better and better into Californication ;-) ...Jim Thompson

And in high end cars flappy paddle gearboxes where the computer does the gear shift without requiring the driver to coordinate anything at all.

Typical auto transmissions seem to be about 10% worse on fuel consumption than the comparable manual/same engine when driven at similar speeds and styles.

Consumer reports is slightly more pessimistic about it:

It seems that there have been a few in the recent past. Lexus and a few other Toyota brands in California. ISTR they blamed the floormats or something. Brake servos don't behave too well when the engine is running flat out. Though I am inclined to blame most of the claimed "unintended acceleration" events on driver error.

The only thing I find with autos is that sooner or later I will forget and declutch the brake pedal when approaching a carpark pay booth (and stopping well short of the window). I drive a manual transmission car.
