74, question the 3/4 pvc is it water pvc(white) or electrical pve(gray) because the dimensions are not the same.
MountainBiker, All of these are great ideas since in a real SHTF(EMP, Solar, Collapse) the electricity maybe turned off and batteries maybe not available anywhere. So trail cameras may not work for the long run.
74 once you set this up and test it then post it all. I like to know if the pvc will hold up. But pvc is cheap and you can make a lot of them so not really a problem.
