Tellart turned an iPhone into a duiPhone with its latest Sketchtools kit. Combine a 3G iPhone, an ordinary store-bought breathalyzer, and the NADA Mobile, which consists of a communication board, sensors, and actuators, and get a useful iPhone application. Blow into the mouthpiece, and the iPhone will inform you if you can safely drive, or if you should call a cab.
We’d like to find out more about the NADA Mobile, since it looks like it could be the start of a lot of fun projects. It’s the latest of Tellart’s Sketchtools line, which can only be accessed if you work with Tellart as a consultant, or if you work with them to organize a workshop for your organization.
