Create a highly portable, wireless access point with Onion Pi. It encrypts all all your net access then sends it through secure Tor servers. It costs $95 and requires a bit of geekery to configure it.
Tor is from EFF. Their free Tor browser covers your tracks by encrypting what you are doing then routing it through multiple servers, thus your location is not traceable. Onion Pi uses the tiny $35 Raspberry Pi computer to create a Tor access point that plugs into an Internet port. Connect by wireless to Onion Pi and everything is routed through Tor.
Feel like someone is snooping on you? Browse anonymously anywhere you go with the Onion Pi Tor proxy. Using this pack of parts and a free weekend you can build a project that uses a Raspberry Pi, a USB WiFi adapter and Ethernet cable to create a small, low-power and portable privacy Pi.
After it’s built, using it is easy-as-pie. First, plug the Ethernet cable into any Internet provider in your home, work, hotel or conference/event. Next, power up the Pi with the micro USB cable to your laptop or to the wall adapter. The Pi will boot up and create a new secure wireless access point called Onion Pi. Connecting to that access point will automatically route any web browsing from your computer through the anonymizing Tor network.
