Faraday Cage Phone Case

thingiverse

This device effectively blocks all communication to and from a cellular phone. In today's technology era, privacy is a rare commodity with devices like stingray cell interceptors, FOXACID servers, spyware and phone taps lurking around every corner. The simplest way to achieve this is by hiding in an unmarked cave without any technology whatsoever. Otherwise, this case gets the job done. I've used aluminum foil inside the case and wrapped the outside with aluminum duct tape. Testing was conducted over a 3G network sans wifi. Mine worked flawlessly after taping it a few times, but what made the difference was having foil inside. The device works by creating a capacitive effect between the inner and outer foils that blocks high frequencies. Using only aluminum tape on the outside didn't cut it, but adding foil inside did the trick. Blocking all signals proved to be a success. Here are the inner dimensions of this build: 140 mm X 22 mm X 78.6 mm **Important Legal Disclaimer:** I won't take responsibility if you misuse this device for any illicit activities like GPS tracking or other monitoring activities not listed here, as per your government's rules and regulations.
