That is a neat link. The under water camera reminded me of a day when the terminal for
our AB 8400B controlled water jet lost the crt. The only place I could find something to
use in a pinch was at Sam's club. Monitor came with a BW security camera.

Anyway, once I managed to get the terminal repaired, the security monitor was 'borrowed'
by a couple guys in our die repair (steel rule dies) shop. They made a waterproof
enclosure with lighting to see what was down hole while icefishing. I don't think it
worked out all that great but they didn't kill the camera.

Isn't it? Those are your tax dollars at work. g The link I provided is
part of the NOAA project to restore the iron warship Monitor:

http://monitor.noaa.gov/publications/welcome.html

There's a good description of the chemistry of steel corrosion in a marine
environment, too, along with some discussion about how they removed the
corrosion for the restoration project. (It's the "Iron Cheesbox" link.) It
will be familiar to some RCMers, but electrolytic rust removal that takes
over 200 days in the tank may be a surprise for some (I've heard of ancient
marine artifacts requiring up to 3 years in the tank)

A fish finder was the first thing I thought of. I could chase those big
trout in a nearby reservoir...

Wow, that is a long time but I was more impressed by underwater flush toilets. How is it
that that bit of technology never hit the text books?

Uncle has done the electrolyic derusting thing with a few items he dragged home. I was
pretty impressed with the results on a post drill.

I wonder how much of the technology of the day used in making that ship has been lost over
the years?

Will your ROV have a ROS (Remote Operated Spear )

Not being an engineer with a practical bent, I can hardly guess. d8-)

I use it frequently, particularly the brush method that's described in the
drop-box archives. I use the full formula that's recommended there,
including the waterglass (sodium silicate). It's probably overkill but it
works great. BTW, my electrode is a slab of Poco 3 graphite I sawed off of
an old EDM electrode, around 8 x 1 x 3/4 inch. It, too, works great.

Good question. There's a lot of information available on the Monitor now.
They also found a jar of pickle relish on board, which they said smelled
really good 150 years later. But it was full of lead from the pickling
process they used then so nobody tried it.

Hey, good thinking! A one-handed CO2-powered speargun probably could be
rigged into that thing very nicely...

It looks like a great robotic project for the kids. Beats playing video
games.

You might like the RC submarines in the tank at Cabin Fever. All you
would have to do is sling a CO2 speargun under one and do some trout
research.

As a materials guy, the floats used on the Nereus may interest you.

Under? I was thinking center of mass but then there is a concern that the hydrodynamics
(drag) of all the structures might cause some unexpected deflection of the spear during
the recoil phase.

Hmm. It sounds like a long reach for a float, but I can see where most
ordinary materials have a problem at 16,000 psi.

Interesting link, Kevin.

The thought was not to modify the submarine. For the spear, compressed
air contained in the shaft of the spear might work best.

Or you might call Dave Barrett and see what it would take to add a
toothed opening to one of these:

I didn't see anything that could pressurize the innards.

PVC pipe and connections?

It's a swimming pool toy on a short leash.


I did some programming work for Perry Oceanographic way back
in once-upon-a-time time. It was fun work.

Rutgers has some neat underwater devices. I especially like this one, which
is especially clever:

http://rucool.marine.rutgers.edu/ind...r-Gliders.html

It completed a trans-Atlantic crossing last month, operating autonomously.
That's some fuel efficiency:

The high school kids back in Washington State built some ROV's with a
longer leash. As I remember they had a 100 ' leash. We changed from
the control system shown here. Instead we ran a reasonably stout
power and return, and then used Mosfets in the ROV to control the
motors. The wires from the control box were something like 22 gauge.
Would have been better to use a microprocessor with a serial i/o, but
that was beyond where the students level of competence. The kids did
understand why running power to each individual motor was not a good
idea for long leads.

As concerns the the AUV, Rutgers bought it from Webb Research (you can
have one too). No development there.
