Frank, love your drawings and ideas. You missed out with the
direction pointer on the camera or you could do it with an extended finger!

Subject: Re: [PSUBS-MAILIST] Periscope Camera
I have an idea for a simple periscope camera.
You all know I like having a ball valve on every hull penetration,
but running a video cable through a hole presents a problem. I was looking at
various types of cameras and came across some "pencil" type cameras.
They cost about $30 and have a little memory chip in them. If it would be
possible to run a cable directly from the camera to a laptop computer or video
screen, then the small size of the camera makes it possible to just push it up
through an opening into a plexiglass tube and rotate the camera by hand.
Here's a little sketch of the concept........
Not much detail in the sketch but you get the idea. I don't think
the resolution on these little cameras is very good but it could be a simple
way to look behind you and still have the ability to close off the chamber
in case of a leak.
