The New Year celebrations are (almost) over, cleaning my home up I noticed several cute tin boxes - potentially useful as Faraday cages.
How critical is it to provide a good-quality (low impedance) electrical contact between the box and the lid? The boxes I have look like that - lid's sitting place on the box is painted over. A cellphone goes off the net when put in the closed box, but is it enough to survive a near lighting strike (with a GPS receiver, a watch and a calculator)?
I'm looking to wash off the paint somehow leaving the tin intact (for corrosion protection).
