improvised faraday cage

[Nix]

Seeing that Aldi's selling incinerator cans tomorrow (£19.99) prompted me to go out to my local hardware store and finally buy a normal can with lid.

Interesting experimenting with this this morning. Radio most definitely won't work (even when the lid isn't on yet) but the mobile still does. A little research later shows that although mobiles work on electromagnetic signals, if the signal is strong enough ie the transmitter is close by, it'll still ring inside the can even with the lid on albeit with a weaker signal.

Interesting. Makes me wonder if we have a massive EMP whether cans like this will be enough to protect sensitive equipment.

Will look into this a bit more. Ideally want to protect one laptop and possibly an ECU from my bikes/car/van. Matter of fact, maybe I should put a spare solar controller in as well as it's got electronic circuits.

The list could go on and on...
