"i'm supposed to avoid high RF devices: car ignition systems, strong magnets as in speakers..."
Stu, contact the manufacturer and get some real information. Neither of those restrictions are sensible. It the devices really have RF susceptibility issues you need the real data of field strength vs frequency and such. Same with magnetic fields, just HOW strong of a magnetic field, how many Teslas?
As you know B drops very fast as a fn of distance for typical small sources so you really need to understand if there is really a problem and what the threshold really is. This is the age of dangerously strong magnets and LED's and very near-field "personal" RF devices. Car ignitions?? GMAB!
Hang in there... Rick

the latest Atlantic has an interesting article on tDCS: Transcranial direct current stimulation where DARPA has been conducting experiments in placing a small voltage directly to the scalp (on scalp not under skin). Even a 9 volt battery with just 2 mA current has had fairly dramatic results.
They find that learning can increase by 10 to 20% and the effect lingers for at least a day. Perception wise , volunteers have had a doubling in the speed and perception making it of interest for military sensors.
Kinda cool, they think it will have benefits for stroke victims, epilepsy, etc..
But i'm not too worried. I disobeyed most of the restrictions in the first week, jumpering a friend's car, reconing a 15 inch woofer, etc. The tech scad me with what looked like those hand held scanner at airports. Apparently the unit has flash memory and a transmitter. He had the readings for the week and all was normal. So was the three week readings. Apparently they can program the trigger sensitivities. Mine is pretty low, so relatively immune to external factors, though doc cautioned me if i noticed my heart (pulse) racing.
So not really an issue yet ( they can increase sensitivity externally).
Just remember nothing is more important than your health... Guess the sins of youth are catching up....... 8^)
