Bypassing regulatory locks, hacking AirPods and Faraday cages

We built it ourselves actually!

The first prototype was just aluminium foil, tape and hope, but we wanted something more solid so we built one out of n°100 copper mesh and some 2020 aluminium extrusions!

You can use a microwave oven as a very cheap faraday cage. Just don't turn it on.

I assume he needed it to have a small opening in the cage to shove the Raspberry Pi through it (to broadcast new SSIDs)

The door of a microwave typically doesn't form an RF-tight seal. Instead there's a groove that forms a resonant trap at the microwave's operating frequency. So it'll probably block 2.4-GHz ISM-band stuff like Bluetooth (I don't actually know how wide the trap band is compared to a BT or wifi channel), but outside that band all bets are off.

You are replying to the article author. He knows you can use a microwave oven as a very cheap faraday cage. He tried that, but it wasn't good enough.
