Hi Frank,
I'm being negative again. It may get in the way closing the hatch & it
doesn't have any height
above the hatch so that you get a bit of warning if you're coming up under
an on coming boat.
I'm sold on the idea I had of building a manipulator out of 3 of your
linear actuators & another motor
for rotary movement & mounting a more serious camera lenses on
that.
That way it could be raised as a periscope with 360 degree rotation, used
to focus in on whatever you are picking up,
be maneuvered to view the back of the sub & shoot underwater footage in
any direction.
( & you could practice with it while it's in the garage.)
Regards Alan.

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.Frank D.
