Brake Light Backpack

MAKE alum Becky Stern is doing great work in wearable electronics over at Adafruit these days. Her latest project? A backpack, fit with waterproof LEDs and Adafruit’s FLORA sew-on microcontroller, that provides high-sight-line brake- and turn-signals for motorcyclists and bicyclists. A FLORA add-on accelerometer automatically detects braking, and the turn signals arrows can be manually activated with a wireless keyfob. Becky makes better video tutorials than anyone I know of. Check it out.
