I would like to add an underwater camera to my tank to get better photos and video of my fish. In Joey's ( king of DIY) you tube videos he often has a "fishcam" (though i think it might be a camcorder and not a webcam) Wondering if others have tried this. I am working on a raspberry pi project (essentially a tiny internet connected computer) and would like to connect a webcam to it. That would be my ideal use case. Any suggestions?
