 Holy cow! Five years in FIRST and it only gets better!
Skyway has supplied wheels to FIRST for ten years.
Ten years ago Dean called Ken for wheels. Ken said yes.
Man, we love helping you guys and gals get good wheels. ;)

Re: Ball speed testing after matches
Assuming the measured length is 1 meter, there is a simple calibration that can be performed to check the speed tester. Simply hold it so the ball can drop through it vertically. Hold the ball close to the first sensor and drop it through. The ball speed should read 2.2 m/s.
Don't belive me? do the math! Hint d=(at^2)/2. If anybody needs more than that post here and I'll walk you through it. I figured this out for our own tester. ChrisH |
