Re: [PSUBS-MAILIST] Alternative to Through-Hull Ports for Electrical Connections

["Ian Wright" <ianwrong@earthlink.net>]

Actually, when I was jotting down possible ideas for building a conventional
steel-hulled submersible, with the goal of reducing the number of
through-hulls, I did consider opto couplers. It seems to me that if the idea
is to transmit through acrylic, the system should work whether the whole
hull is acrylic or you utilize an existing viewport.
