The company I work for is in the engineering software business (PICs are a
hobby for me), the turnover rate in Pune is so high, you just have to wait a
few weeks for a new opening to turn up.

High burnout rate? Lack of knowledge and quitting? What do you think
is the cause of high turnover.

Other than being in rust belt, it's neat around here, bike and hiking
trails everywhere, Cleveland pops Orchestra has a labor day concert on
our little town's court house steps, no hurricanes, poisonous snakes,
insects. But we do have deer (son-in-law hit one on I-271 last week).
Housing is modest priced with a wide variety. This facility (I don't
work there) is about 30 miles west of Cleveland and 10 miles South of
Lake Erie and has a reputation of being good to their employees.

yeah, i have been very happy here the past thirteen years. And had
a lot of opportunities. Most our employees tend to stay around for
a while (certainly not all).

It is primarily an mechanical design house, so the EE would be the
top-dog EE, so to speak. Largely self-directed.

If anyone is interested, I have a job posting in word that I would
gladly forward. Maybe you know someone that is looking. Today is
the last day of internal posting (we always post these internally
for current employees before going outside)

Elyria, just (5 miles) South of Lorain. It's Ridgid tool, the red pipe
wrench people, but the do a lot more than that including the See Snake.
see http://www.grainger.com
search key words for "See Snake"

I have lived in the area for 35 years.

Carl,

My wife has a cousin that lives in Elyria. I can't recall the exact
address right off,
but I could take you there. They live near a place called Dairy Treat
or Tasty Treat or
something like that.

Is the furniture store (I think it's a furniture store) that has the old
man rocking on
the side of the building still there?

My wife's sister and brother in law used to live on Palm Ave in Loraine.

Tasty treat is on the near northeast side of Elyria, it got torn down
and rebuilt recently. THe rocking chair is still there on the corner of
State route 57 and North Ridge road. It's a HVAC repair company. We are
in Lagrange, 5 miles south of Elyria off state route 301. It's
semi-rural with lots of Field corn and Soy beams planted. Your relatives
are within a mile of the Ridgid tool plant.

Don't think so, try a major subsidiary of Emerson Electric Co. Some of
the other things in the area include Parker Hannifin (Aircraft
hydraulics, fuel pumps, brakes and wheels), Bendix truck brakes (Anti

power wheelchairs), Cleveland air traffic control center

Oh, I am very relaxed, just came back from Local astronomy club had open
house at the near metro park, was star gazing a bit.

p.s. If you didn't pickup on it, Since I haven't purchased any Phizer
products, I couldn't make the connection with the little blue pill. :)
:) The other thing is somewhat related to the Ridgid calendar, which was
available free to good customers at plumbing supply houses. I see the
calendar can now be purchased in the states only. See:

I second that. It appears that there is a significant demand and
supply doesn't seem to match up to it.

I didn't think it was politically correct to make that sort of calendar
these days. Didn't Pirelli (the tyre company) give up on doing their long
established one?

We tried to replace it with more politically correct
images afew years ago. There was such a customer uproar that
it was changed back immediately.

I can't speak for the company, but several years ago there was a fuss
about it as offensive. I don't know the what happened since then history
wise. It used to be there was a calendar hanging in nearly every shop
that had anything to do with construction and maintenance. Today in the
USA it is not thought of being good taste to display one in particular
in areas accesible to any gender. But I believe the RIdgid calendars are
tastefully done, and not in the same class as other modern day calendars
(playboy, hustler, etc.). My wife has some years back stopped by the
Ridgid plant and picked calendars for me to take to work. :) And I
guess this is getting away from the [EE] thread.

Sheesh, at my school the photography department puts out a self-made
calendar like that every year and no-one complains... Then again, they
include a few guys in it too...

Given the company name, it will likely be the last bastion of tool girl
calendars...

...as long as the ladies can have equal time, I see that as a good thing.

http://www.cbsnews.com/stories/2006/10/13/ap/national/mainD8KNKEB00.shtml
"(AP) A group of Marines and ex-Marines who fought in Iraq _ including two
wounded there _ is featured in a beefcake calendar being sold to help
wounded veterans. "

The trick would be getting Rigid (or anyone else) to post a link to the
veterans beefcake calendar from the page for their cheesecake calendar.
http://www.freedomisnotfree.com I can't imagine that Rigids customers would
object to that, and it would do a lot to quiet any feminine groups that
might be offended.

No matter what your political leaning, you have to admit that these veterans
deserve more than they get, and that it is a healthy thing for the ladies to
be able to look at something nice as well.

Pass this idea on to the management?

Come to think of it, the girls in the pictures of the Rigid calendar are as
well dressed as any you could see on any sunny beach these days, the
calendars that tend to be regarded as 'un-PC' tend to have them less covered
...

And then there are the charity calendars, like
http://www.daelnet.co.uk/rylstonewi/ as featured in the movie 'Calendar
Girls', or the various ones firemen around here do for other charities...

So can the PicList round up enough eye-candy for a calendar?

I brough an oldish book (last century) into work yesterday, and found a
photo of myself wearing a yellow suit tucked inside. Dunno about eye-candy,
but it caused a bit of mirth. One bloke admitted to owning a pale blue
safari suit; he claimed his mother brought it, and he only wore it once.

It could be the "badly dressed engineers of PicList" calender. Groovy.

Awesome, I'll send in some pictures of me caving... just immaculately
dressed and smelling of mud.... Or maybe some when I still wore a fanny
pack...


My first girlfriend way back in grade 9 took all of about three weeks to
quite literally march me off downtown and have me buy clothes that
weren't so horribly dorky. At that tender young age I was already
wearing more than my share of computer tradeshow swag... I'd already
found that getting into Comdex (18+) at the age of about 13 involved
nothing more than wearing a tie, smiling, and claiming I owned a really
good razor.

The calendar would also include each month's PIClister's favorite
12-line snippet of PIC assembly, and a one-sentence Lesson Learned
Through Failure.

My two most recent:

"Check for unrouted traces before sending the Gerbers off. ...Idiot."

(why isn't that part of the Eagle DRC??)

and

"When making an Eagle package, don't take the pin numbers from a diagram
in the data sheet that shows the package... upside down..."

Lord knows...

"Print out a 1:1 copy of your gerbers and see if the mounting holes on
your board are in the same galaxy as the ones on your associated LCD
screen... idiot."

> "When making an Eagle package, don't take the pin numbers from a diagram

Nice... I caught myself happily laying out traces to an IC recently on a
complex double sided board, LED digits on one side, smd parts on the
other. Unfortunately said IC and the digits were on the same side...
stupid xpcb and it's lack of keepouts...

Actually, that's an easy one -- if you are hand-routing any portion of
your layout, you want to be able to get a clean DRC before you give the
autorouter a crack at the rest of it.

It's easy enough to type "rats" and get the message "Nothing to do!" if
there are no more airwires.

I don't know how Eagle works, but in Orcad I make a point of turning off all
the layers and showing only the global layer to see if there is any rats
nest left - even tiny dots get chased down and sorted out.

Don't think Orcad or Eagle are located in NE Ohio, maybe change the

My father (a house builder) had an older generation carpenter working

Oddly enough on that same I ended up kinda changing the laws of
geometry, or at least layout.

See, these are rather large, current sucking, 2.5" high 7 segment leds.
In my usual fashion I figured I'd put one 1.5A 7808 regulator per led to
drive the common anodes.

But it's such a crowded board, oh where oh well will I put all those
regulators?

Fortunately the LEDs actually have two parallelogram shaped pockets on
the backside in the middle of upper and lower boxes formed by the digit
segments...

Hee hee! You made a board layout joke!

Best I've been able to do in that regard is to rotate a 9V battery by
something like 18 degrees in order to fit it in amongst some standoffs.
Fit so tightly, I didn't need to do anything extra to hold it
stationary, even when you shake the case. But that was mainly serendipity.

Gerbview?

Or just send the .brd file to your boardhouse (if it is Olimex), no need
to gerber....

That's worse than Star Trek jokes isn't it?

I once did that on a project too. I had to fit 64 circuit boards, each
controlling a stepper motor, onto a big 2ft by 2ft plate. I'll have to
admit I designed the motor driver boards first without thinking how I
was gonna fit 'em all in. (hey, I was working 12-16 hours days for a
month...)

Of course they didn't fit length wise until I tilted them ever so
slightly...

Yes, much. Or better.

It's an impressive array, and I'm glad I wasn't there for the final
plugging of motors to drivers.

But... are they tilted up from the horizontal, or just around the
vertical axis? If it's the latter, I'm not sure I get why it helped...
though it definitely looks more aesthetically interesting.

Be glad! The leads on the motors are rather short.

Looking at it I'm not so sure either. I tried playing around with the
original cad files, the boards are rotated 9.78 degrees, and the after
rotation clearance from board to board is 0.05 less than before rotating
it.

My best guess is that after rotating the *mounting* posts have about
double the clearance between them, an extra tenth of an inch. I must
have been thinking how I was going to get a tool in there to tighten
them.

That's what I thought! I always underestimate clearance for boards
wired to one another.

Ah!! Now that makes sense.

And maybe the mounting hole drills would be uncomfortably close together?
