I made one and it worked great until my son and his buddy decided to reverse the polarity while they were messing around with it. They blew the camera and rather than take the sealed camera case apart and rebuild it, I just bought an aquavu. If you google lunkercam, you will find all kinds of information about them and they also sell the cameras and kits to build them. They are really pretty simple to build out of PVC Pipe and fittings.
