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, <yaaaawn>. 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.

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. > You're living in the past...

There's a reason why even new automatic transmissions run hotter than gear boxes. And warmer = more losses. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

Nonsense, it's a stuck accelerator pedal. So shoving in clutch or pushing PRNDL handle into neutral... what's the difference? >> > >They should start teaching the basics again in drivers ed.

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 ;-) >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. 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. > > >> You're living in the past...
