If you have ever gotten turned around in the woods you know situations can go from exciting to terrifying in moments. This project uses a bunch of Adafruit gear to create a jacket that lights up and is motion responsive.

Hrudin shares a great write up and thorough tutorial on Instructables:

Improvements in lightweight and wearable electronics are opening new possibilities for bringing technology into the backcountry and using it to increase the safety of those who explore. For this project, I drew on my own experiences with outdoor adventuring to imagine the future of my favorite outdoor clothing brands and increase wilderness safety without being GPS-enabled.

The Mountain Safety Jacket uses the Adafruit FLORA board to control FLORA Pixel LED strips embedded in the wrists and hood of a jacket. Like many headlamps, the wearer can toggle through several light settings to adjust the brightness and color of the LEDs. While the jacket is in use, a simple tilt switch senses whether or not the wearer is moving; after the wearer is motionless for 15 minutes, the circuit triggers the LEDs to flash endlessly, making the wearer more visible to rescuers. This flashing can only be deactivated by resetting the circuit using the FLORA board embedded on the back of the hood.
