Here is a video of the automated hoodie working on continuous mode. The upcoming version of the hoodie will attach the Arduino to a sound sensor, and use loud noises as the trigger to put the hood up. For now, the hoodie goes up, goes down, and keeps going. This video also explains the materials used.
The code for the automated hoodie is available for download from sourceforge, with all five parts including final code and in-progress code, code for use with the heart-rate circuit and for use with a button, &c. It was developed primarily by Daniel Miller as an alteration of the preexisting servo codes from the Arduino examples library.
In its original form, the automated hoodie was meant to be triggered by a heart-rate sensor — high heart-rate, hood goes up. It was meant to offer protection in times of anxiety. However, the circuit used was too sensitive to be used in a wearable electronic, and the project has since changed.
