PirateBox allows you to quickly setup a mobile wireless file sharing network. Basically, it’s a P2P file-sharing device that can turn any space into a temporary, but secure wireless file sharing network.
Multiple users within range of the device can connect to the network without any log-in and immediately start downloading or uploading files via their computers or mobile devices. As it is not connected to the internet, the system is secure from outside attacks. Also, users remain anonymous as no user logs are generated.
The PirateBox is made up of a wireless router and light-weight Linux server connected to a USB hard drive. It can run on AC power or on batteries for portability. Feel free to make your own with the help of detailed instructions on how to build your own PirateBox for about $100.
