Mans Shapshak really, really wants to play some tennis this summer. To improve his serve, he reasoned, he needs to perfect that initial toss of the ball in the air. And what better use of a spare Wii remote’s accelerometer than, say, rewiring the Wiimote to measure the speed of his throw?
“This same technique,” Shapshak writes, “can of course be used for any repetitive activity that you want to repeat exactly every time for consistency. Think golf, bowling, etc.”
