    Re: A DIY Faraday cage: caveats and hints?
    From: Dennis Jewitt

    I have used similar tins with paint removed around the lid and box contact faces.  The contents are also wrapped in kitchen type Aluminium foil.     On the other hand we have never experienced a lightning strike.  Presumably a direct strike on the box  would be the end of it due to high current.    We just stow the box well away from the shrouds and hope for the best. 

    Kind Regards

    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
