Another point to consider may be to design in
modular flexibility in the initial phase
so the OSS can be easily upgraded or modified
for individual tastes. The major components
we're looking at are all based on tried and true
technology but we are also opening the doors
for personal ingenuity in order for the sport
to progress.
1. Length; 4-5 meters?
2. Diameter; 1m?
3. Speed ; 4-10knts?
4. Range or dive time; 6hrs?
5. Safe dive depth; 100m?
6. Size windows; ? porthole or dome?
7. Exterior shroud for hydrodynamic efficiency?
8. End cost less any outside labor; $20-30k?
Just thinking out loud, here's a few concepts
I've been playing with using StrataVision3D 5.0

OK. You have a lot of opinions. :) Ready to help compile that list of those interested
and the skills they bring to the table? A landlubber is perfectly suited. Furthermore,
you seem to grasp the situation perfectly. I don't think we need to worry about a new
server at this point, but I have a server I would offer to the cause if it ever got to
that point. What I would like to see is everyone who has expressed interest to either
post their wish-list or e-mail them to myself or you...:) So we can compile a preliminary
spec. It will probably change a bit as time goes on, but it will give us a place to start!
Please, all, spec the following:
1. Length
2. Diameter
3. Speed
4. Range or dive time
5. Safe dive depth
6. Cost window
7. Further commentsIt seems like lead acid is the power source of choice. I can handle a PWM speed control,
so I don't think we need to worry about potentiometers or anything like that. Batteries
and motor should probably be stored outside the pressure hull. Steel seems to be the
pressure hull material of choice. Gauges and electronics should be left flexible, to
accomodate a variety of tastes, needs, and budgets.Let's agree to use DXF for electronic drawings and TXT or HTML for text.
