As an avid fisherman, I would love to see an underwater fishing camera. Even something that I can tie on to the end of a fishing line and cast out would be fun. I'd really like to see what's going on down there.
I thought about using a cheap (under $20) underwater flashlight as a housing. A micro SD would be good for data storage. I wouldn't mind having to unscrew the flashlight to turn the camera on.
I took apart a cellphone that I have too look at the camera. Its small, but I have no idea where to go from there. I can build things like this with instructions, but I don't know enough to do it on my own.
I would assume that the best, or easiest, route would be to simply buy a small video camera and go from there. I am open to suggestions.
Thank you.
