shielding a computer / keyboard / mouse ?

Hi, I joined the group 3-4 weeks ago and have been reading back
messages. I have a lot to ask and say but am trying to minimize
computer time, esp. since I got an "extended sensitivity" trifield
meter that shows that I am sitting in a maxed out Electric field right
now (4 feet away from my flatscreen monitor but obviously touching the
keyboard).

My pressing question at the moment is about computer shielding. I
don't mean the monitor, which was all that I used to worry about, I
mean the fact that the entire computer (desktop) and even the mouse
and keyboard are putting out huge fields. You have to get several feet
away from them for the field to start to drop, and so you can't use
the mouse or keyboard at all.

My most obvious problem so far has been with magnetic fields, and I
have been going to extreme lengths to get away from those. But I'm
afraid my symptoms are getting worse, and want to minimize exposure
but this computer thing is hard to figure out. I looked at lessemf.com
but they do not seem to grasp this problem and only focus on shielding
the monitor or getting away from IT.

It appears that anything plugged into the computer, including
headphones, mic, etc. all carry the field full-strength, including
along the entire length of the cable.

any ideas? I didn't see any discussion in the archives, not that I
could track down.

thanks for this Group!

Hmmmm, I'm at work now and am happy to report that the keyboard and
mouse here do NOT register on the Electric scale of my Trifield
meter, so it is not a general rule after all, which is good!  

But it leaves a mystery what is going on at the house. I am staying
at my sister's in the one room in her house that has low magnetic
EMFs and is my sleeping refuge (the rest of the house fluctuates
greatly). Another oddity is that the phone lines there also register
really high on the Electric scale, even with no phone attached. This
was the same weird situation at my house, from which I had to leave
recently -- and my headaches have much improved as a result. (Power
lines outside the house cannot be changed. My physical problem
started, however, as a result of frying beneath a compact fluorescent
light mounted over my pillow for 7 years.

thanks for any comments.

Hmmm, could be an electrical problem with the outlet the computer
is plugged into? Like it is not properly grounded. You could
buy an inexpensive outlet tester to see if it is wired correctly.

Generally, people here don't seem to worry much about their
mouse and keyboard. Although, with wireless versions becoming
more popular, perhaps they will...

(me, I've got an old-fashioned wired keyboard and a wired
"ball" mouse)

Agreed. It is not neccesary to have high electric fields from the
keyboard/mouse, especially if you are using a desktop computer.
Grounding your computer case should cure the problem completely. If
your computer has a 3 prong (grounded) plug, it should be already
grounded, so there could be a problem with the grounding in the
outlet or the grounding inside the computer. If your computer only
has a 2 prong plug (rare for a desktop), I would suggest running a
grounding wire from a metal screw on the computer case to a known
electrical ground (sometimes the center screw of the outlet cover
works well). Also, with a 2 prong plug, you might try first in the
computer "the other way" an see if that helps.

I had/still have some problems because laptops are usually not
connected through 3 prong plugs, and therefore often have high stray
electric fields, whereas desktop computers usually are grounded and
don't usually have those stray electric fields.

Hi Soula,

I have found the electric scale is only noticeable near power lines, or
unshielded wiring inside the walls.

When you said you have power lines at your home, that piece of the
puzzle clicked in place.
Try walking under the power lines with the meter on, and then walk away
from them. Try to pick a place where you can get 1/4 mile from all power
lines. See if you feel better. It might take an hour for your nervous
system to unwind, depending on how affected you are.

things turning on and off. Like the fridge or heating.

Magnetic readings also go up and down, from the Amount of Current
flowing through power lines, if any are nearby. This can also apply to
wiring inside the walls, especially if the wiring Gauge is too small.

I also get a higher body voltage reading near the phone wiring. Which is
another way of measuring electric fields.

Frying is an appropriate word to use.

Sounds like you are on the right track.

Do you have high fields from the peripherals when the computer is off? How
about when the computer is unplugged? Do you have a different keyboard or
mouse that you can try with this same computer?


These simple tests may shed some light on the source of the problem.

If you need to shield electric field from a mouse or keyboard, lessemf.com
has several shielding fabrics (see high performance mesh and veilshield)
that can be used to cover a keyboard and/or mouse. They also have shielded
gloves. Make sure you use a ground cord with electric field shields.

Hi Soula,

I don't have any info for you as I am a newbie to this subject too
but I have a question:

I feel very uncomfortable and invaded by energy sitting at my
computer and was surprised to find that there were no readings on my
regular Trifield meter where I am sitting.

Now I understand that the Trifield meter is not particularly
sensitive so I am wondering what kind of readings you get on
your "extended sensitivity" meter and where you got it?

I have moved the tower right away but I still can't stand being at
the computer long. What's more, the more time I spend at the
computer, the more bothered I am by the EMFs elsewhere.

Best wishes,
Aline

Thanks for replying, Marc and Garth -- I have been unable to read
messages until I finally came back to work today (because of the
wiring problems which make my own computer/keyboard/mouse put out a
high electric field, I have not been plugging it in). I'll try to get
time "between work" to write some.

My computer does have a 3-prong cord -- it is the house wiring (1910-
built
house) that is screwed up and so nothing is ever actually grounded,
apparently. Outlet testers show a variety of results from different
receptacles in the house, but this appears to be meaningless since
when I tried plugging a long grounded orange
extension cord in to other places in the house that were
supposedly "ok", I still got the high electric field from the
entire computer and any peripherals plugged into it. Same thing from
anything else in the house as well as the metal plumbing
fixtures (not so wide a field though). I have 2 outlet testers, and
some outlets show contradictory results on one or the other tester.
So I am staying away from
anything plugged in, as well as some walls that put out a high
electric field for 4-5 feet, and some ceilings when the lights are
switched on (crawling on the floor is okay). I turn on the water
with a rubber spatula. What a hilarious sitcom this would make.

QUESTION: I don't suppose it would work to attach a grounding wire to
a metal screw on the backplate of the computer and take that out the
window to a grounding rod? Seems unlikely because it would still be
attached to the rest of the ungrounded system, right?

thanks for writing, Emil! Trying to squeeze in some time here at
work, where the computer is "safe" ...

Yes, the high field from computer and anything plugged into it
(headphones, mouse, etc.) still occurs as long as the computer is
plugged in, whether it is on or off. It is the old-house wiring that
is the problem; the grounding is non-functional (in spite of the
little circuit-testers' evidence to the contrary! -- some receptacles
show OK and others do not, but plugging into none of them produces a
grounded computer).

I am getting desperate and so am very interested in the shielding
material idea. There are so many choices at the lessemf.com website.
Can someone share what material would be best (cheaper is definelty a
factor right now) -- I picture myself in a shroud sitting before my
computer, wearing special gloves and poking at the keyboard.

But it all has to be grounded as well? How would I achieve that, I
wonder? With a grounding cord going out the window to an 8-foot rod
in the ground? Fortunately I am on the first floor, but still such a
thing will not be easy.

Dear Aline, It is no wonder you feel that way, if your situation is
like mine. I got my original Trifield meter in the early '90s, then
put it away till this last year. And it does NOT really show the
electric field, in spite of looking like it should! Only the magnetic
field -- which was truly affecting me (symptoms getting worse and
worse the past few years till I finally started figuring things out),
but the meter was giving an incomplete picture.

Only because someone I found had the "extended sensitivity" version
(and brought it to my house and showed me new things to worry about)
was I clued in to this issue. And when I went to order one on the
alphalabs website, I could not find it -- you have to actually phone
them and demand it ("my boss didn't put it on the website" I was
told). So I ordered that (an extra $10) plus the "Broadband" extra --
another $10 (but I am not sure that Broadband thing is worth a cent).

I know what you mean about 'the more time I spend at the computer the
more bothered I am elsewhere'. And I think back at the years of
sitting holding my mouse and getting that feeling of "being
connected" -- it gives me chills.

good luck! keep writing,

I would think it would work fine to attach a grounding wire to a
grounding rod in the way you describe. I would unplug the
computer while installing the grounding wire to prevent any electric
shock hazard in case there is a fault in the computer power supply.

Finally, I grew up in a very old house with knob and tube wiring -
many of these old houses have quite high magnetic and electric fields
because the old wiring did not run in matched pairs, and therefore
did not cancel magnetic/electric fields. I'm not sure what the
cure is unless you want to rewire with modern wiring. Grounding the
computer won't cure the fields throughout the house due to unmatched
wiring.

Dear Emil, just getting a small chance to skim the manifold details
of the lessemf.com website -- it is PACKED with information which I
hope to get the opportunity to read soon. In particular all the links
in the "EMF Safety News and Information" section.

Meanwhile, I am trying to understand the fabric pages immediately (so
I can order some). Therefore I have some questions.

Considering that I want to make a little tent-like garment to sit
inside, with gloves sewn on (and maybe with a faceplate or eye-slit
of as transparent a shielding material as possible), and that what I
am trying to shield against here is Electric fields, could you tell
me:

1. Do I need to be concerned about Conductivity/Resistivity ratings?
If Yes, then:
? Do I want a fabric that is conductive? (I don't understand this
issue)
? What is resistivity, and how does that relate to conductivity? (I
assume less resistivity is best?)

2. dB:
? the shielding is rated in dB. This dB is often shown in relation to
something in MHz and GHz. Does this have to do with what sort of
field is being shielded? What would the electric field be, if so?

3. Electric field shielding:
? Are there some listed fabrics that do NOT shield the electric field?


-- I am chemically sensitive, so would want to stay away from
anything that offgasses or is not nice to skin. It looks to me like
these 3 are left after filtering for these issues:

- NaturaShield -- 20-35 dB
- Ex-Static Fabric -- cheapest, but what is its dB rating?
- Zelt Fabric -- 80 dB

? Are there others that would be appropriate that I have missed?
? Should I get enough that the fabric closes under my feet at the
bottom?
? I assume it needs a grounding wire?

thank you so much.

I have both of my computers grounded. On one I took a sheet of metal that I got from the hardware store and made a case out of it. I attached it to the wall about three feet above the ground to prevent ground currents I grounded the metal case to a grounding rod. The case is about ten feet from me and I use estensions for the cables to the monitor. This one works best. The other computer sits on top of some metallic cloth and it is groundedto an outlet with a cord that only plugs into the outlets ground. I am going to redo this one and ground it to a grounding rod instead. I can feel a difference in the energy that comes from the computer that is grounded toan outlet and the one that is grounded to the grounding rod. I will no longer ground anything to ground outlets and everything will be grounded to grounding rods. This is the conclusion I came to when comparing the two recently when I grounded the bed I was sleeping in. Grounding rods give a very comforting kind of energy where as the outlets make me feel like I'm being electrocuted.

[Non-text portions of this message have been removed]

wow, that is very interesting.
That sense of being electrocuted as you describe, seems familiar.

Oh, how long are the grounding rods that you put into the earth?

What are ground currents, by the way? You must have connected to
some really strong studs or something to be able to suspend all that
metal casing and a computer 3 feet above the ground -?

Do you think you will need individual grounding rods for each
computer or would connecting both to one do as well?

I use 8 foot grounding rods. Actually the computer case is on a shelf. Ground currents are what I used to feel on my floor before i put all my electronic equipment above the floor and in faraday cages, etc. I have many ground rods at my home grounding many things. It is easier for me to ground things that way but I would "guess" it is okay to use the same ground rod toground more than one computer.

rod. The case is about ten feet from me and I use estensions for
the cables to the monitor. This one works best. The other computer
sits on top of some metallic cloth and it is grounded to an outlet
with a cord that only plugs into the outlets ground. I am going to
redo this one and ground it to a grounding rod instead. I can feel
a difference in the energy that comes from the computer that is
grounded to an outlet and the one that is grounded to the grounding
rod. I will no longer ground anything to ground outlets and
everything will be grounded to grounding rods. This is the
conclusion I came to when comparing the two recently when I grounded
the bed I was sleeping in. Grounding rods give a very comforting
kind of energy where as the outlets make me feel like I'm being
electrocuted.

RE Sheilding Fabric - I have used Swiss tulle Bobbinet, in particular I have
used a head-net, but I find it has a limited shelf life especially if worn
about the body. What is you advice on this ?!! any advice welcome here. I
will be looking to design a sleeping shelter which I will take with me on my
holoidays but I am put off by the aforementioned wearing out of the material.

thanks
