Passive EMI shielding?
 
Hello, If I had a small circuit I would like to shield from EMI, what could I use to do this? I don;t want some $100 solution. Thx for the info guys.

A earth grounded copper mesh or sheet around the circuit.should do the trick:)

if you need a small shielded box, you could make it out of unetched pc board material, and solder the edges together....

Somebody was telling me that anti-static bag-the type you get components and PC cards in would work but I am not sure. Any opinions on that?

anti-static bag?

Try sticking your mobile phone in one and watch the signal strengh meter, then ground the bag an see what happens.
