Unless you compete at the competitive level, rarely do yo have the luxury of a referee and scorekeeper while playing ping-pong. It's all up to you and your opponent, which often leads to heated off-table battles over a point. So why not let the net, at least a smarter net like Stiga's SensorScore, keep track of the score for you?
Powered by four AA batteries, the rig includes an LED scoreboard and a pair of vibration sensors that are mounted beneath each side of the table. By keeping track of how many times the ball bounces and whose serve it was, the SensorScore net is able to automatically keep tabs on the score, announcing points and when it's time to change serve. And unlike your opponent, it has no vested interest in cheating, and unlike real-life refs, it can't be bribed. [Stiga via Fancy]
