Kinda cool, $1.00 windmeter
- Thought this was kinda cool, I had to resize the image to get the correct
dimensions before printing, the article states that since the newer table tennis
balls are larger in diameter there is a 2,6% error if you use them, the old
balls are 38 MM if memory serves, the string length is 25 Cm. I'll have to check
it with my digital for accuracy. it seems to me a bubble level mounted on
top would aid accuracy.
