Maybe I missed it but did you make or buy the Faraday cage?

Maybe I missed it but did you make or buy the Faraday cage?
- thel3l 2y agoWe 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!
- avidiax 2y agoYou can use a microwave oven as a very cheap faraday cage. Just don't turn it on.
- NavinF 2y agoYou 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.
- staticfish 2y agoI assume he needed it to have a small opening in the cage to shove the Raspberry Pi through it (to broadcast new SSIDs)
- wiml 2y agoThe 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.
