Getting the perfect shot can be difficult, especially when the subject or object is moving at a high rate of speed. Specialized equipment is often used, such as high-speed cameras and remote digital triggers to capture images at just the right moment, which carries a hefty price tag.
Matt Kane of Vela Labs has designed a high-speed trigger that’s both effective and will not break the bank. In fact, the trigger costs just under $2 to make provided you already have all the other materials. Matt’s trigger setup consists of a visible (as opposed to IR) laser, reflective mirror and sensor board to capture high-speed objects. The sensor board is outfitted with a phototransistor, 3.5mm jack for a Triggertrap flash adapter connection, an octocoupler and a couple of resistors soldered to an Adafruit Permaproto board.
The cost for the trigger materials costs just over $1.44 minus the Adafruit board (which is more expensive than a typical breadboard), laser and reflective mirror. The trigger itself allows cameras to grab objects moving at 400fps, albeit with a little motion blur but it is still impressive.

If you trigger an external flash along with the camera you should be able to get a much sharper picture.
That’s exactly what I’m doing! I’ve got a few more details on the setup over at DIY Photography: http://www.diyphotography.net/build-22-gallon-high-speed-photography-studio/
I like your plastic storage container studio. I probably would have over thought and over designed it and ended up with a heavy plywood box. I wonder how you could reduce the flash period to freeze the bullet.
The flash problem is what I’m working on right now. Aiming for a Kickstarter later in the year.
