looking to get a little more creative with your photography and fancy giving high speed photography a go? Why not create your very own high speed camera trigger using a Arduino, piezoelectric sensor (as a sound sensor), a DSLR camera and an external flash. Watch the video after the break to see it in action.
If your not sure what an Arduino controller is : Arduino is an open-source physical computing platform based on a simple microcontroller board, and a development environment for writing software for the board.
