Remote controlled flying saucer driven by a pair of iPhone devices and four fans.

The podcopter project consists of a set of applications for iPhone designed to enable remote control of a flying-saucer vehicle. The software components are broken into:

1. Controller iPhone: used by an operator to direct the flying saucer using onscreen controls and the iPhone accelerometer.

2. Device-mounted iPhone: used to regulate the speed of four onboard fans and add basic stability logic to the vehicle. Four fan controllers built into the flying saucer read the light intensity from corners of the iPhone's screen and adjust fan speed accordingly.

The controller and device-mounted iPhones communicate over WiFi and automatically discover each other using Bonjour.
