Review on 📡 TitanRF Faraday Fabric Kit: Shield RF Signals with Military Grade Conductive Material (WiFi, Cell, Bluetooth, RFID, EMF Radiation) - Includes TitanRF Fabric, Tape, and Instructions by Daryl Barton

This material has many uses. I'm not really interested in contact tracing unfolding, I'm not a big fan of fascism so I wanted to make a blackout case for my iPhone - done, it completely dwarfs it. (I used 2 shifts) Swipe the part between Bluetooth devices blocks the connection, the headphones turn off and they disappear from the list of available devices. I'm wondering if this can be used to jam BT enough to render it unusable but still be able to receive calls. I still have some experimenting to do but I'm very happy with my RF blocking abilities.
