Baseball photography - with SCIENCE!

We used an acoustic trigger to take a well timed photo of a ball being hit. We added a 1 millisecond delay to the photo so the ball is shown just jumping off the bat. Note the slight "squish" of the ball. I made the acoustic trigger by using a piezo element to bias a transistor which in turn switched a silicon controlled rectifier.

A special thanks to Daniel and his dad for being a good sport and swinging in the dark.
