introduction and computer setup

December 21, 2006

Hi,

I've just joined the group so I thought I would introduce myself.

I've had EHS for 5 years - initially getting headaches,

concentration/memory problems from mobile phones/WiFi; about three

years ago I became sensitive to lcd monitors with skin burning and

physical/mental lethargy and since last winter I get the skin burning

reaction to lots of things like fluorescent+low energy bulbs, my car,

computer network cables/adsl etc.

I'm only able to use a computer now by having the computer, adsl line,

networks etc 10m away on the other side of the house and trailing 15m

monitor and keyboard/mice extender cables to the room I work in. For

a display I use a Toshiba ff1 led projector in rear projection mode

and a combined keyboard and mouse which communicates by infrared with

an adaptor near the projector. The projector and keyboard IR receiver

are 3m away from me. I still have some mental dopiness after using

this set-up for 4-5 hours and this may be due to magnetic emissions

from the infrared keyboard when the communication LEDs are pulsed.

But I can't have a wired keyboard or mouse on my work table without

getting a burning sensation on my chin/cheek/underside of my

nose/tongue tip so this is definitely better. The other obvious

drawback is that the projector is dim and low resolution (800x600).

I have experimented with remoting the keyboard processor of the IR

keyboard and also optically isolating a wired mouse so that it isn't

being polled by the computer multiple thousand times a second. I

didn't find either of these solutions better than using the IR

keyboard. Both of these ideas were inspired by

beyond experiments is that I don't have sufficiently sensitive

instrumentation to measure fields other than from my own symptoms.

And as EHS is progressive I don't want to become even more sensitive.

If anyone is interested in this I can provide details/photos.

I know from other EHS people that they have problems with display

cables so I was interested in using fiber optics to transferring video

and keyboard/mouse signals. One route is via fiber optic USB 2.0

extenders which are starting to become available but these are

expensive (£500-600), does anyone know off any less expensive

alternatives.

Best wishes to all,

Rod
