Re: [PSUBS-MAILIST]( ebc) ectronic buoyancy control
Hi, Giuseppe . . .
SportSub was originally designed and manufactured
in Surrey, B.C., Canada. I visited the plant and got a few
surprises.
One was that the lifting point was built right
into the fibreglass. I expected metal bracing - something. Of course
that showed more my ignorance of fibreglass construction than anything
else.
The other thing was that no matter how ugly a
submarine is, it is cool.
The SportSub did/does have an automatic buoyancy
control that was electronic. The electronic controls
were designed by a fellow by the name of Hugh Daskin. He used to
(still does?) teach a course in how to design a submarine, again, here in
Vancouver. I've been out of touch with him for a long time so . .
. I Googled him and the only thing that came up was a post
I sent to PSUBS back in 1999 about battery boxes!!
Personally, I feel that the use of electricity
underwater should be kept to a minimum. As you know, second stage
regulators are extremely reliable and are sensors all by themselves. I'm
using five of them only because I need the extreme flow capabilities in case of
a rapid descent. My dry cockpit (two person), even though quite strong,
will not be a pressure hull. It won't be able to withstand large pressure
extremes.
If you prefer the electronic route, it's possible
to use a float at the end of a rod that is connected to a potentiometer.
Connect it to a gauge and life's is good. Electronics is not my strong
area so I stay away from it.
Gratsi per la complimento!! ;-)
