„BlimpDuino is a very low cost open source autonomous blimp. It consists of an Arduino-based blimp controller board with on-board infrared and ultrasonic sensors and an interface for an optional RC mode, a simple gondola with two vectoring (tilting) differential thrusters, and ground-based infrared beacon. It will be available as a commercial kit, complete with a mylar envelope, in late 2008. The target price for everything you need for an autonomous blimp (aside from helium) is $100.“
