Meet the PI-Link: a nifty gadget that turns your smartphone into a speed radar. You can use it to measure your performance when playing certain sports. You simply have to connect this module to your smartphone and put it on a tripod to measure your pitching or throwing speed. This can be used for various sports, including hockey, racing, softball, and other sports.
The PI-Link combines with your phone to generate 6-second clips. The app is smart enough to detect ball speed as it leaves your arm. You will be able to go through your past results on your phone. This module is getting funded on Kickstarter.
