The do-it-yourselfers at Adafruit have provided step-by-step instructions for turning a Raspberry Pi into a Tor proxy and wireless access point. A good project for users looking to anonymize their Internet traffic, “Onion Pi” requires just a Raspberry Pi, a few standard peripherals, and some work in the command line.
You’ll need a Pi of course, an Ethernet cable, a Wi-Fi adapter with an antenna, an SD card loaded with the Raspbian operating system, and a power supply. You can buy all these from Adafruit in the companys Onion Pi Pack, but the components are pretty standard and could be obtained from many other sources. A portion of sales through Adafruit will go to the Tor Foundation.
This is timely. Sounds like another good way to put a Raspberry Pi to use.
