I'm surprised that you didn't know about them, didn't you
work on a
dairy farm before? Were your cows degaussed?

No, I never worked on a farm. Perhaps you are thinking of my
short
period with Express Dairies?

We NEVER had a cow on board - not as far as I'm aware! ;-)

I knew about degaussing computer screens but not ships.
Interesting.

They do it themselves. The 25"+ Sony Trinitron screens made a
****ing loud
noise.

Older ones had a button to do it.

Really? I had a BnW TV as a kid, and even that didn't have one. Must
be an
American thing, they never design things properly.

Lots more you can find:

I thought we were talking about TVs. Yes I had one monitor (an Iiyama
vision master pro) with a degauss button, but it was pointless, since it
activated on every switch on, and was only needed if the surrounding
magnetism had changed, like moving it, which would have meant it was
unplugged and would have degaussed itself anyway.

The static was more fun. Charge yourself up on a monitor in the
office,
then
tap some one on the shoulder. Strangely, it was them that jumped
and not
the
person doing it. Maybe just the unexpected?

For whatever reason I tend to build up a lot to static... shocking
myself
and
others. I have mostly just gotten used to it.

I had a colleague who couldn't handle any computer parts as he was
guaranteed
to kill them with static. Probably his clothes or shoes come to think
of it.
Everyone blamed him.

I have been known to kill parts by zapping them. Have killed more than
one
mouse that way, too.

A mouse is not static sensitive.

Corded mice are.

And I'm the opposite, I can't kill things with static. I used to touch
the frame of the PC first, but now I don't even bother with that. I
certainly never used a wrist strap.

I don't either but don't have carpet.

Most sensitive stuff has a diode to absorb high voltages anyway.

Wrong.

It is extremely rare for an unprotected pin open to the environment on
equipment. There are many types and ranges of protection devices depending
on the application.

Not rare at all with the video connector.

With an IC the only examples I have seen are analogue chips without any
protection on an input to reduce internal leakage currents.

Many FETs don't have any gate protection, this is a well known example
(2N7000):

Others do have protection:

There was one time I broke a graphics card though. I had wrapped a
computer I was selling in bubble wrap. I undid it to make a last minute
change before posting, and the unwrapping built up a very big charge on
me. When I lifted the computer, I touched the DVI graphics socket
first, and felt a sharp shock in my finger. That output no longer
functioned.

So much for the purported diode.

Quite.
