David,
that's great news that things have settled down & you escaped the fire.
Now you will just have the dust from the demolition & a couple of years of
construction to listen to.
   I have just started an online plc programming course with view to buying
a PLC or PAC & HMI. I believe you were going to go down this track & are
trying to keep your build in line with either GL or ABS. You are welcome to
copy what I am doing or collaborate if you want! I am looking at leaving the
programming part till August, but that could change!
I am doing a few things differently. I have had electronic pressure sensors
made up with a fitting compatible with a first stage regulator high pressure port
& am water / pressure proofing them. So no high pressure coming on to
the sub. Also I will be sampling from 3 oxygen sensors as in a rebreather system
to top up the O2 level. James Camerons boat did something similar. I may do
this with the CO2 sensors also. So the system will sample the 2 sensors that
are closest in value to each other & be able to detect a faulty sensor.
Let me know what you are up to in case I can help.

Cheers Alan
P.S. get Y to plant the flowers!

> Hank, you amaze me at your ability to get things done. I can't even get the cnc ribs I had cut a month ago assembled. But that could be because of the fire around here, (missed my home thanks to the wind currents, or that I have to rebuild my future shop if I want a dry indoor space for a winter project, or the 400 lavender plants that need to be planted for our lavender and honey business. So keep building so I can live vicariously thru your sub projects.

>> Hi All,
>> I have been thinking about my next project to compliment Gamma and Elementary 3000.  I am thinking about adding an ROV.  I can mount an ROV garage to the front on the opposite side of the manipulator.  The manipulator is close to completion, and I don't have much else to do.  I can use the same rotary actuator motor type that I just built for the manipulator for thrusters.  I have a real nice aluminum strobe light housing  that can be used for the camera.  I probably have most of the stuff here to build one.  I might need some help with an umbilical cord though.
