 - **Tor WiFi Network** - Using [OnionPi](https://github.com/breadtk/onion_pi), you can create a second wireless network, that routed traffic through Tor. This is very light-weight so can be done with just a  [Pi Zero W](https://amzn.to/2Urc0hM). Here is a configuration [guide](https://www.sbprojects.net/projects/raspberrypi/tor.php)
 - **Faraday Case** - If you want to block signals for devices such as car keys, smart phone, laptop or even just RFID-enabled cards and passports, you can line a box or pouch with [Faraday Fabric](https://amzn.to/2ORKtTr)
 - **GPS Spoofer** - If you don't want to be tracked with GPS, then using a SDR you can send out spoof GPS signals, making near-by GPS-enabled devices think that they are in a totally different location. (Wouldn't recommend using this while on an airplane though!). You can use [gps-sdr-sim](https://github.com/osqzss/gps-sdr-sim) by [@osqzss](https://github.com/osqzss), and run it on a [Hacker RF](https://greatscottgadgets.com/hackrf) or similar SDR. Here's a [guide](https://www.rtl-sdr.com/tag/gps-spoofing) outlineing how to get started, you'll also need a [NooElec HackRF One](https://amzn.to/2Ta1s5J) or similar [SDR](https://amzn.to/39cLiOx). Check your local laws first, you may need a radio license.
+- **No-Mic Laptop** - You can go one step further than using a mic-blcoker, and physically remove the microphone from your laptop. (And then use a removable external mic when needed). See how, for [Apple MacBook and iPhone](https://www.wired.com/story/remove-the-mic-from-your-phone/) | [Video Guide](https://www.youtube.com/watch?v=Eo-IwQMeVLc).

+- **Laser Surveillance Defeater** - Sophisticated spies could potentially use a laser microphone, which bounces an invisible infrared laser off of a window and back to a light sensor. By measuring any interference in that reflected light, the laser microphone can detect vibrations in the window pane and reconstruct sound on the other side of the glass. A laser surveillance defeater creates small in-audible vibrations, which can stop all vibration-based evesdropping.

 - **Faraday Cases** - A Faraday cage or Faraday shield is an enclosure used to block electromagnetic fields. This can be really useful for electronics, since many devices are constantly transmitting and recieving, which is the worst when you are trying to avoid being tracked. Their have been numerous reportings that governments can apparently track phones, even when they are [powered off](https://slate.com/technology/2013/07/nsa-can-reportedly-track-cellphones-even-when-they-re-turned-off.html), and since smart phones often do not have removable batteries, the only option is often to shield them from any em waves.
