This is my first PI project so please excuse my noobness.
Project: Motion activated battery powered camera with long battery life.
Speed: Take picture within 1 second of motion trigger.
Problem: PI draws too much power while on so it must be powered off until motion trigger but it doesn't look like it can boot in less than 1 second.
Is there any way I can hack an image sensor to take and store a picture quickly while the PI boots up and then once the PI is booted, it reads the picture?
Thanks for any suggestions.
