Here is another example of where the inexpensive Wiimote controller with all of its built in sensors nicely adapts itself to an other application. In this case the wiimote is used to determine how good a tennis serve is!
“Well that sounded like a plan so I poped open my wiimote soldered in a few wires to the minus key and then taped the wiimote to left arm (I am right handed).
Then I taped the other end of the wires to my thumb and wrapped a tennis ball in aluminum. So now when I had the ball in my hand it completed the circuit and pressed the button which registers the data in the software. I then toss the ball and when it leaves my hand it unpresses the button stopping the registry of the data from the accelerometer.”

But how exactly is the quality of the serve assessed based on the data you gather from the accelerometers?
