Project: To get images with my iPhone 6S+ of a fox visiting our garden over night. One approach I?m considering is to tap the button of a Bluet ooth camera shutter gadget (from CAMKIX) with a 500 ms pulse to a solenoid, triggered in various ways. (I don?t want to crack open the tiny ca se to attempt that with a circuit mod.) That seems reasonably straightforwa rd.
But to get a VIDEO clip, far preferable, I need a second pulse, to stop it.
I?m thinking I would need three non-retriggerable monos. The first would be triggered by a +ve going signal from one of my sensors. (Such as a thin nylon trip wire or a micro switch under a large lightweight panel, cu nningly disguised.) It would last 500 ms, activating the 12V solenoid. The second mono would be be started by the terminating edge of the first. Its d uration would be say 20 s and it?s terminating edge would trigger t he final mono, another 500 ms, stopping the video.
Does that seem reasonable please? Any other suggestions?
