Some people have done some incredibly useful and clever things with the Raspberry Pi in the short time it’s been around.
Here’s another fantastic project, this is called Onion Pi and it’s a hardware WiFi Tor Proxy!
An extract from the Adafruit web site reads:
Feel like someone is snooping on you? Browse anonymously anywhere you go with the Onion Pi Tor proxy. This is fun weekend project that uses a Raspberry Pi, a USB WiFi adapter and Ethernet cable to create a small, low-power and portable privacy Pi.
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.
Cool project 😎
