Can anyone help me with this conundrum:
I've built a wall that measures how hard a golfball hits it. This force measurement is converted into a distance measurement, so I can gauge how far my golfball would have traveled. It is useful to me as a golfer. However, it would be far more beneficial if I could measure the ball spin at impact. This would tell me if I have hit a slice, hook, block, etc.
The ball impacts 3"memory foam. What can be used to measure the ball's spin? Some type of embedded wire grid? HELP, Thank you, Bob
