Design

The device interface board is the interface to both the cameras and the cutdown device. It consist of 2 transistors for each camera and one for the cutdown device. These transistors act as logical enablers. They allow us to turn on the power or shot switches and trigger the cutdown device by passing current into the base of the transistors, allowing current to pass from drain to source.

A single input pin is available for both cameras, so both cameras are triggered together. Future designs may change this to allow us to trigger one or the other.
