Posted a general overview of how to make your electronics more waterproof including updates to the PVC housing system we developed.
The DIY water proof connectors, and the way we mount pressure sensors under mineral oil might be of particular interest.

How to mount sensors on PVC housings
Re: How to mount sensors on PVC housings
After waterproofing you need some way to test the stuff right? We needed a way to test our little falcon tube loggers and household water filter housings are a good solution as the domestic water pressure range of 40-80psi overlaps nicely with sport diving depths. The internal clearance of that 4x10 filter housing is only slightly larger than 4.5" x 9.5" but could accommodate a good range of other dive computers, lights, etc.
