Op Amp Calculations

Hi Jim,

can you please elaborate on why? I presume because of the 2nd transistor....

Cheers Terry

Thanks Jim, thats pretty much what I figured. Its like driving, really. any fool can drive on a straight, flat road with no traffic and good visibility. Going round a corner sideways in the pouring rain, with a logging truck coming towards you, sorts the men from the boys.

I drove the Pennsylvania Turnpike from west-end-to-east-end one time with an eery feeling of never quite touching the ground ;-)

Aawwaarrkk!!

When one drives all the way across the country at one go, one gets that feeling at various points.

Well, if we're going to play "Can you top that" ;-)

Drove across Oklahoma one winter in so much cold rain that I had to defrost using the air conditioning :-(

Newer vehicles have that feature... this was in 1964, when A/C was still pretty much "add-on".

Ever tried fishtailing on the freeway at 55MPH on black ice? That's kind of a rush too. ;-)

I drove I80 W->E across PA on about an inch of ice one time. It was raining and freezing so fast that I had to put the defroster on high enough that I had to open the windows so my hair wouldn't catch fire. ;-) We finally broke free of the storm around Stroudsburg after 10 hours of white-knuckle driving. We only had about three hours driving time to get home but the wife said, no (*she* was too tired)! We stayed the night in a hotel, only to fight the storm again the next day. :-(

Oh, yeah!

You had an Oklahoma?! Wait...

(The AC in my truck is on whenever the defroster is on)

I learned to drive in a '56 Mercury station wagon, in '56 ;-) The power steering failed as I was trying to pass "parallel" parking. I managed to get it in the space anyway ;-)

You misspelled "feechur". Forcing one to run the compressor when using the defroster is nutz!

Had AC been invented? ;-) I learned to drive on a '64 Ford Custom (in '68), no AC, no auto, no power (brake or steering). I bought a similar car in '78. A (then) new Ford Granada ESS (also no AC, auto, or power); great car! No one would believe there was ever an ESS with a stick. ;-)

I think the weirdest driving experience I've ever had was the summer between 11th and 12th grades. I had a "summer job": part time busboy/dishwasher. The commute was about 10 miles, on Highway 12, which has since been replaced by I-94. (Wayzata to St. Louis Park, MN.) Anyway, it was a really really boring drive. I had heard about "highway hypnosis", and all that safety stuff they try to indoctrinate kids with. Anyway, One time, I got off work, jumped in the car, headed down the highway, and the next thing I noticed, I was already home. And this was before I drank, smoked, or smoked! (but I was 16, so could have been a victim of testosterone poisoning. ;-) )

(the point was, there was about 10 minutes of commute time that I completely spaced out on and didn't even remember driving. If I'd crashed, it would have been my fault. I guess that's when I decided, "In the car, be on Red Alert at all times!")

Cheers! Rich

Oklahoma, hm? OK, one time driving from So. Cal. to Minnesota, while passing through the OK/TX panhandle, there was a dust storm. Visibility was about 100 feet. On the right side of the highway, I spotted a cinder- block building with "COLD BEER" painted on the side in 8' high letters. So I stopped. I mentioned "Gee, I've been snowed in before, but this is the first time I've ever been dusted in" or some such clever thing. The bartender said, "Welcome to f***in' Oklahoma."

Sometimes, being snowed in isn't all that bad of a deal. ;-)

Or, if you like cold, there was the time my thermostat got stuck (in MN) and snow was coming out the vents, until the radiator hose popped.

Cheers! Rich

Split the difference?

.062" Gack! I don't think my feeler gauges even go that high ;-)

Use a piece of old PCB material?

The examiner was so impressed that I could drive the '64 tank that he let me parallel park where there were no cars. Even then I shifted into the wrong gear (missed reverse - into second), but I don't think he noticed and I didn't make the correction. ;-) He took a couple of points off for crossing the center line on a turnabout (impossible to do otherwise with that car, on that street/driveway), where others were failed the same mistake.

My son had it "easy" though. He took his test in my '93 Eagle Vision TSi (power everything, 300HP - don't stick the foot in the gas ;). During the road test the #1 plug wire decided to open[*]. The examiner asked if there was something wrong (a mechanical failure was an automatic fail). The kid said that he didn't notice anything and continued on.
