I wondered, "WTF MEMS???" so I looked it up.

Sh*t man f*ck - it ain't that far from reality! Nanomachines! Buckytubes!
The one-atom motor!

Or is that a whole nother level of reality?

Thanks,
Rich

I assume you haven't seen the collections of MEMS images at:

http://mems.sandia.gov/scripts/index.asp

Take a look at their "image gallery" section at the bottom of the page for a
group of micro photos of MEMS devices with some microscopic bugs included
with for comparison. Or their "Gears and Transmissions" section for some
lovely photos of microscopic gears and matching linkages.

The "Movie section" is also good but I don't have a high speed connection
for that.

I chose .25V because one POR circuit requirement was for an active low
to be guaranteed above a .25V VCC, until the power supply was within
spec and stable for some period. Forcing a low voltage with a .25V
rail, under worst case conditions, wasn't an easy thing to guarantee.

A low VTH N-Channel?

Well, it was 30 years ago, so no low Vt's. It wasn't my circuit, but
IIRC Germanium NPNs were the only solution that worked, barely. (and
what a PITA to get them approved, even then). ;-)

My usual way is to generate a LOW for the region VTH < VDD < BG-Ref*
plus a time-out.

* BG-Ref = bandgap reference

Seems reasonable. I guess with a 0Vt you should be able to get a
decent POR circuit.

In this case I need a POR to last until the charge-pump has reached
final value, WITHOUT loading the charge-pump with any current.

If you think the obvious, you will guess my solution, but I can't
confirm or deny it ;-)

Well, I'm one of those humorous digital guys, so what do I know? ...but
if I had to guess, I'd guess a mirror.

You forgot the smoke ;-)

Oh, no! We silly digital folk package our magic smoke on the

Anyone have pointers on how to make your own screens for sand blasting

<<SNIP>>

Several people have suggested that. I'll check it out. My wife comes
up with this sort of customized-frosted-glass project often enough,
maybe I should invest in my own cutter, particularly now that I'm
officially a registered Girl Scout, I'm the cookie "mom" this year

word of warning... I'd a work related blasting process some years ago and
noted some interesting stuff from the hazard/safety reports. There are a
number of grits used in the blasting processes, all have a generic dust
hazard but common builders sand should be avoided.

The dust, when lodged in the lung, is particularly carsonegenic. I remember
there are quite a number of resources online that will point you in the
right direction.

I hope this helps.

Hi Rich,
I've been working with Target for 1 year now.Like every other program it
has advantages and disadvantages.Before I worked with Eagle
(Cadsoft).Eagle is easier to handle.You get a good schematic and a sharp
layout on the screen from the beginning without much adaptation of default
values.In Target you can adjust almost everything ( drill, trace width,
case outlines...) in your schematic and layout without going back to the
device-library. If you know how and where to adjust these things it is
very comfortable. But just there lies the crux.The menu is confusing and
the online-help and handbook are lousy.The default colors of schematic and
layout are miserable without your intervention.It took me about 3 weeks to
get a screen image that was acceptable to me.So what? there are people who
like Target (Forum) others are more sceptical (I).I think it depends on
your experience.Target is very flexible but at least for me difficult to
get accustomed to. Eagle is easier to learn, I guess.

Hi to all,

I've been looking at some low end $400 to $1000 Schematic capture and
PCB layout programs. What seems like a new kid on the block is the
TARGET3001 CAD program.

http://www.ibfriedrich.com/english/index.htm

Feedback one their website is all very positive, no surprise. I've
spent a little time playing around with it and it looks pretty solid.

What I'm looking for is feedback from other users of the program. Is
this package as good as it seams, or do I need to take off my rose
colored glasses.

Thanks in Advance,

Hello Rolf,

Some time ago, when only workstation had enough computing power I was
trained on Mentor Graphics. I was not a great fan of it, at all.
Than for different smaller projects and to be faster with development I
used Orcad. When Orcad run under DOS it was outstanding at that time.
As some people on the boards wrote several times, the newer Orcad
versions are not that great anymore and people said, that parts of the
tool still run with patches in DOS background.
Agreed, Eagle it is easy to use and straight forward, but as most
projects have something special on the board, e.g. special IC, cut out,
mechanical integration, unique routing I found, that Eagle has
limitation. For simpler projects it is good and with the evaluation
level not bad. But particularly, when you change something on the
screen and it does not come out the way you draw it this can be
frustrating. You play for a long time until you found out what it is or
you give up.

This is in my humble opinion the beauty of TARGET3001. The IBF
companies philosophy is WYSIWYG (what you see is what you get). And
that is really true. Also having good CAD drawing function can be
sometimes very helpful.
You are right, there are more elements which can be modified for the
user and as with any program you need to go through the learning
process. But once you know the right mouse clicks, short cuts the tool
is enormous efficient. The thing for me is I don't want to pay xk $
for a tool and than on top support fees. Target is a good balance
between pricing and performance and they keep adding on functions. I
like the tool and with the easy gerbering function a nice round up.

Your input on the poor help menu is something you should place on the
TARGET forum
http://www.ibfriedrich.com/cgibin/forum_e.cgi
or send an email to IBF (target@ibfriedrich.com). The company is more
than happy to get feedback and improve their product. This is important
that the tool need to improve with the hardware and software changes.
Also if you have technical problems, I found that IBF usually posts an
answer within 24 hours and I assume if you email them the same will be
true - all for free, what a deal. This kind of service running on a
big boy's tool will cost you.
Regards,
...richard

That's how to INSERT delay.

Given F(s), what's the time delay versus omega?

Given your first post, I would have answered as Mr. Gaddi did.
However, it seems now that you want either group delay or
phase delay. Since phase delay is pretty obvious, I'm guessing
it's group delay that you want. Given the Laplace transfer
function, F(s), substitue j*w for s, then take the derivative
of phase with respect to w. That is group delay. (Pronounce
'w' as omega.)

I don't recall a small one from Adobe but some websites use a small
colored button with the letters PDF that are close to the right size. A
couple minutes in any graphics program should give you something you can
use.

Pretty easy to borrow small example ones from other websites
(Digikey's are pretty small, 17 x 19 pixels). Right-click, Save Image
as..

As to making such a symbol track the size of the text as the user
adjusts it in whatever of the mainstream browsers they may be using...
I don't know how to do that or if it's practical, but a web developer
should be along any moment to give a definitive answer...
