    well that was a fail, I started doing some basic tests but the barometer kept slowly moving indicating a leak, I gave it a coat of superglue but the leak remained. So I eventually just put the whole thing underwater to see where it was coming from, to my surprise the connector started bubbling. turns out the air was going though the wires insulation to the outside. so this time i have stripped it down and conformal coated the whole board apart from the sensor ports, this should also seal around the wires.

    Progress!

    I have rebuilt the barometer chamber. But this time I have used some high strength clear adhesive. And I packed it so there was only a tiny air gap around the  sensors so there is no way for the air to get to the wires.

    I have been giving it some time for the glue to cure before I do any testing but it looks good when i give it a little pressure as its not changing over time. im going to try and get it installed in the sub and tested sometime this weekend. i still need to program the inav controller logic switches to operate the ballast pump. My plan is to have a 3 position switch that changes the output so it can switch between static and dynamic diving depth control, and I still need to install the depth sounder too.

    Are you going to use telemetry as feedback?
