Figure 24 - Testing the completed relay controller using manual pushbutton switches

The completed relay controller circuit board was once again connected to the camera and powered by a 6 volt battery pack. The small solderless breadboard shown in Figure 24 has two pushbutton switches that are connected between the relay driver inputs and the positive supply voltage so that both relays can be tested with the camera. The circuit worked perfectly on the first attempt, and it was also discovered that this camera did an autofocus if only the "shoot" button was pressed without using the "focus" function first. That means I could have got away with only a single relay and switch, but it can't hurt to have a proper timed focus control as well.



This universal camera trigger hack can now be controlled with any microcontroller or electronic circuit using a low current, low voltage signal line. Because the relays simulate the operation of the original dual stage pushbutton switch that was pulled from the camera, the system can be interfaced to any external device without risk of damage to the cameras internal electronics. This simple hack will allow a multitude of spy gadgets to be built, using the high resolution imaging system in the camera to acquire your information automatically, triggered by some external event.
