[GTALUG] Question

[Alvin Starr]

You can never be paranoid enough.

What your looking for is a tempest enclosure.
Its basically a Faraday cage but tested to NATO et al 
standards.(https://en.wikipedia.org/wiki/Tempest_(codename)).
A bunch of years ago I was dealing with CSE and got to learn that you 
can read a CRT screen from a good distance away (I vaguely remember it 
was on the order of a KM or so). There is apparently at least 1 tempest 
building in Ottawa that got screwed up because someone cut some holes 
for plumbing.
So your not the first person worried about others capturing your 
radiated signal.

Not that long ago I read an ACM article talking about being able to read 
an LCD screen in the next room from RF and then there was another ACM 
article about being able to read a screen from the reflection off a 
persons eyeballs.

So to keep completely safe.
1) remove the battery
2) wrap it in aluminum foil
3) wrap it in copper foil
4) solder the edges.
