There’s a tiny coach in your basketball

There are tons of gadgets to help golfers develop the perfect swing, but it’s hard to apply the same unobtrusive training tools to other sports. Evo One, though, is the counterpoint — it’s a Kickstarter project that puts a tiny coach inside a basketball to help players improve their game. A small gyroscopic sensor detects backspin and emits a whistle when the ball is shot correctly, allowing players to make corrections as they play.
