Some people assume that taking up a course in Tae Kwon Do will make you a kung fu ninja master overnight. This just couldn’t be further from the truth. It takes years and years of dedication to reach black belt status. But once you reach that point, there is little that can stop you from kicking an epic amount of ass.
The Tae Kwon Do Vest is a sweet little wearable project which enables users to measure their kick strength using a series of piezoelectric sensors, an MCU which cues a hit detection scheme and a set of wireless transmission crcuits for emitting a specified byte of data when a kick is detected (also detected via the massive pain in your chest.) A special receiver system translates the kick strength numerically then displays the numbers on a screen.
