This fun toy, shaped exactly like a Ping Pong paddle, allows the user to play a rousing game against an invisible opponent.

The Self Table Tennis senses how hard you are swinging and plays an appropriate volume sound to match. There are three game styles- easy and hard rally and rhythm mode. I’m still a little unclear (even after watching the video) how you win or lose points but it looks like fun to just swing the racket around and hit invisible balls around.

It looks pretty nifty, but seems more like a technical challenge to me. Could a microcontroller and an accelerometer have any seasoned maker heading in the right direction toward a DIY version of this? [via Craziest Gadgets]
