Shake it, fishy....

This is going to be my Easter holiday hack: to integrate an accelerometer chip (e.g. Wake on Shake board from SparkFun Electronics) inside the housing of an action cam, to trigger a video when the camera is being accelerated or in other words, ideally as soon as a fish pulls on the hook-less bait, the camera starts recording for a fixed period. CamDo Solutions published a really cool trigger option for a GoPro.....I reckon the same must be possible for an angling type underwater camera. The camera would need a wireless function to transfer files instantly. The tricky part fill be to fit everything into the casing and configure the wake and shake to the desired acceleration speed.
