David,
I would appreciate it if you could make this publication
available to me.
Guide me to the appropriate web site.

Martin,
David Douthit's recent story ("Help make a difference") is fairly
rare.
That was Ken Carlile's story. I was sympathizing with him.
As to your issues there is an August 2001 report that simply states
COTS hardware is neither safe nor reliable enough to use in mission/flight
critical systems.
This report was paid for by the FAA. They are not "happy campers"!!
If you would like a copy I have it in electronic (PDF; 125 pages) format.

Dear Colleagues
>From time to time on TechNet I have been very interested to read of
people's
experiences with designs that left something to be desired, whether it is
from board fabrication, assembly or Design for Test perspective. My
challenge, as one of the contributors to a PCB design course, is to tell
people how to do things properly.
It has been very useful from this perspective to have Earl Moon's latest
offering as an example of the kind of checks which it is advisable to do
before diving into the pool.
As you would expect, most information says how to do it, and very few folk
are prepared to hold their hand up and say that "my design was less than
perfect"! David Douthit's recent story ("Help make a difference") is fairly
rare. What I would love to do is to be able to illustrate points of bad
design, and I wonder if anyone has examples which they could let me use for
student training.
Ideally I am looking for physical samples, but clear high-definition
photographs would also be of relevance. Obviously I would be happy to
acknowledge the names of the guys and the companies who are able to help,
and would be very sensitive about not exposing the names of designers/design
houses, to protect the guilty . . .
If anyone is able to help, perhaps they would contact me off-line.
Grateful thanks for your help.
Martin
