    A DIY Faraday cage: caveats and hints?
    From: Tony Oz
    Date: 2019 Jan 22, 03:06 -0800

    Hello.

    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).

    Please comment.

    Warm regards,

    Tony
