Faraday cage?


Dusty Chalk

Recommended Posts

Anyone here built a Faraday cage? Strikes me as pretty easy. I've got some sort of RF source in my vicinity here at work, and am tempted to build one for my audio equipment. Basically, it needs to be (a) made of conducting metal, (B) continuous (all conducting materials must touch each other) and © ventilated (so heat doesn't build up). Does it need to be grounded? I am not sure I understand why if it does.

Well, no, they (the electrons) don't need to go anywhere, they just "gather" on one side (the positive).

Airplanes aren't grounded, and they're cited on the wiki as an example of a Faraday cage that protects its contents (passengers) from sudden charges (lightning strikes).

Thinking out loud (which is almost always a mistake -- I liken it to chewing with one's mouth open), I would think that if it works for highly localized DC-ish potential transients, this should extrapolate rather readily to AC.

I'm going to just get some slabs of metal and jumper them together and see what it does. Or maybe I'll just bring in my Singlepower Supra++, as that has a metal casing.
