A fishcam can make ice fishing more interesting. You can sit in a chair and see down the hole in the ice without having to lay on the ice.
An inexpensive fishcam can be made from a webcam out of an old Toshiba laptop, attach it to an otg cable, put it in a piece of scrap metal tube that has a hole drilled for the lens, cover the lens hole with a small piece of glass glued with marine epoxy to get a clear picture and prevent fogging of the lens. Seal everything with silicon and epoxy a 1/4 inch nut to the pipe to attach to a selfie stick.
View the camera on an otg compliant tablet or phone with the android "USB Camera" app .
