I love this idea. I dream of being able to do more than just lock all my devices in a bottom drawer, buried in towels.

      I’ve wondered about faraday bags. Have even seen a few DIY sites that describe how to make them? Might be fun just to see if I could make it work.

        The concept’s pretty simple. You want to make the gap between conductive elements smaller than the wavelength of the signal you want to capture.

        Basically you’re creating a gaussian surface. So the smaller the wavelength from like microwave, the small area of e conductive grid needs to be. If your grids larger than your wavelength then the radio signals can still go through.

        This is why a completely enclosed metal box is a very good Faraday cage.

      Microwave/ferriday bags are fine. But they do not prevent the microphone from working. Sound waves will still go through a bag. And if the phone is compromised which we’re assuming it is in this model, then the phone can just record the audio and wait for a network signal to upload it later

        But if you’re in a hurry. Put whatever you need in water. Water is an excellent conductor. Usually. So if you put something in water it’ll have a very hard time transmitting radio waves through it. If you want to preserve some electronics put them in a bag first.
