Need advice on using computer inside of a metal trailer

[Guest guest]

Hello all,

Been a long time since I've posted here; I think my username used to be " R.ticle

One " , but it's been so long that my address expired.

I may be spending some months in the more rural countryside; in fact, I'm going

there to check the place out and run some tests in a couple of days.

I would be living in my trailer (mobile home) on the property. It's of a

typical design (built on a steel chassis with aluminum walls).

I need to be able to use a computer and the internet for the bit of income I'm

making right now. I also need to be able to use the computer in my trailer;

unless I can convince the property owners to replace their WiFi with ethernet

cables, ditch the CFLs and get corded phones, I don't expect I'd want to use a

spare room in their house! (And believe me, I will try to teach them to change,

but I can't guarantee they will).

Some people might simply say, " Computer in a metal trailer? Don't do it! "

However, I don't have much choice in the matter; I need to be able to for the

sake of earning any money right now, so the best advice you could give me is

about how to do it in the safest way.

I need to mention that there are already a number of " safeguards " to make this

an electrically " cleaner " computer setup:

-The 19 " LCD monitor is modified by Low EMF Office in Italy (the fluorescent

tubes are replaced with low power LED strips; the control board for the screen

is enclosed in a metal box on the back of the monitor; the cables are shielded;

the monitor's switching power supply has been completely replaced with a large,

metal-enclosed, very low-electrical noise linear power supply, which powers both

the screen's control board and the LED lights).

The monitor emits virtually no magnetic and electric field, and though there are

some noises on the AM radio, most of them " drop off " within 8 " . They are

certainly much better than on a " normal " flat screen monitor!

-The computer is a small, low power, fanless system. There's no motor making a

fan spin, so no RF from anything moving. The hard drive is solid state; no

spinning parts. The computer is in a solid aluminum case and kept a few feet

away. AM radio noise is present only at an inch or two from the machine at

most.

-The keyboard is a Macally Icekey, which has relatively little RF.

-The computer does use a switching power supply, but it's *relatively* low-noise

compared to most I have seen, and it shielded from radiating more than an inch

or less away, and its output to the computer is running through two medium

performance RF powerline filters and a high end ferrite torroid, so it doesn't -

at least with what I have to measure, and hopefully that is sufficient - conduct

much RF noise into the computer.

-The AC power which will supply the computer/monitor with electricity will be

running through a fairly high performance powerline RF filter (in case there's

dirty electricity from the building it'll be plugged into), and the filter will

be grounded, as well as the metal box the filter will be in.

________________________________

As you can see, this computer system is already much cleaner, electrically, than

the average setup, which may make it safer to use in a metal trailer.

However - I still need to hear from the knowledgeable folks here - ideally,

soon, if you've got time to pitch in by the end of tomorrow or sooner - what

else I need to do.

The trailer's layout dictates that the only place to put the monitor will be,

perhaps, a couple of feet away from the wall of the trailer, which is separated

from the outer aluminum wall by perhaps a couple of inches of space or less.

There will be a glass window nearby.

I feel I should ground the trailer to conduct any lower-frequency RF generated

by the computer (assuming, even that they reach the aluminum walls of the

trailer) to earth.

Is this logical thinking?

If so, how should I do it? I was thinking a steel plate mounted on the side of

the trailer near where the computer would be, with foil around the edges and

thick copper wire going to a ground rod in the earth.

Is that the best way? How deep should the ground rod be in the soil?

Is it a lighting risk?

Should I try to move the monitor even further from the trailer wall (remember,

there's limited space to work with).

What about cables (the ethernet cable I'll use - which is, for now, ordinary,

but if I stay long term, will be shielded - and the monitor's cables and AC cord

that powers everything? Should they be kept far from the trailer walls? Or does

it not matter if the trailer wall has grounding on it?

Sorry for the lengthy message; gotta go now, anyway, my fingers hurt (not from

EMFs, just sore joints!). Sorry it's short notice, but any help from you as

soon as you can will be much appreciated.

Thanks kindly! Keep well.
