Once upon 
    a time, we set up an acoustic trigger to catch bullets in flight.

It was 
    so much fun, I've decided to build an advanced bullet velocity detector.
    Hopefully, when fully implemented, the laser tracker will be able to time 
    the strobe so as to
    catch the bullet at some predetermined point in space to the nearest millimeter.
    I'll let you know how that works out. Here are some pictures of the prototype 
    hardware.
