The minimal but powerful setup of a Raspberry Pi, WiFi dongles and a power bank is packed into a flat and lightweight acrylic housing fastened to the Server Entity. Apart from wardriving, it runs a web server, router and regular access point, which can be used for both general internet access and advanced file and information sharing. After connecting to the wireless access point, the user has immediate internet access - if a nearby network was hacked by a Server Entity.
