First attempt - Laser trigger

Using a few spare parts, and a Prototino from SpikenzieLabs, I built a laser light sensor. When the laser is interrupted, the attached camera, Canon 5D mk II, fires at high shutter speed. Strobist info : Flash on above camera, home made diffuser, high speed sync feature on. First attempt, no effort put into a pretty picture set. Stay tuned, more to come.
