The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I have uploaded some pictures, and I have decided for the main seals on the electrical connectors to rely on RTV-8 Silicone, which on the original seals which used this particular type I had little issue with as long as I strengthened it.
I changed from the Ammunition Case to a Double Pelican Case (a 1520 houses the electronics, and the 1520 is inside of a 1600 giving a double hull design for every electronic component except the CPU and Battery which have individual Third Hulls - I'd love to see water reach these things lol)
The Pelican 1520 Case inside the 1600 Case, each has an O-Ring Seal and a Pressure Purge Valve.
A view of a Cooper Waterproof Electrical Connector, in my submersion tests these things held up pretty well (this one is unsealed when photo was taken and is meant for the electromagnets, hence the lower gauge wire than the others)
A view of a Cooper Waterproof Electrical Connector, in my submersion tests these things held up pretty well (this one is unsealed when photo was taken and is meant for the Bilge Pumps which need a thicker gauge wire for the higher current, I simply used a cut up power cord for these)
The Pelican 1520 Case closed up inside the 1600 Case
A Closeup of the Outside portion of the waterproof connectors, the rubber molding makes a decent seal on it's own but it is being given a generous amount of sealant as well.
A frontal view showing the connectors for the rotation bilge pumps (turn left/right) and the electromagnets which actuate the Scuba BCD
A Top view of the outside Case (minus the Fiber Optic Feed Through)
Scuba BCD (back side) which stands for Buoyancy Control Device
Frontal View of the BCD
Type SC Fiber Optic Terminations
80 feet of now sheathed Fiber Optic Cable surrounded by Vinyl Tubing (due to its flexibility)
A closeup of a section of tubing and the fiber cable inside of it.
A PCV end cap used in the PVC Compression Fitting for the Fiber Optic Feed Through, not in photo is the addition of "Coax Seal" Tape.
A view of the massive amount of Silicone used to support the cable and seal the feed through
The Compressed RTV-8 Silicone, it is like a Whipped Cream can, you bend the nozzle and it is propelled out - VERY easy to work with!
The Seal on the top part of the Fiber Optic Feed Through to the 1600 Case
The whole top of the Fiber Optic Feed Through in the 1600 Case
The Bottom Portion of the Fiber Optic Feed Through, sealed with RTV
The Ethernet switch which will allow the CPU and Two Video Feeds to share the Fiber Optic Tether, very compact and operates at 9V
A Sealed Cooper Waterproof Connector
A Heat Shrink like Coating Compound, makes a nice flexible seal for individual wires
Acrylic Coating Liquid, used to coat and seal entire boards and used to seal the 1520 Case Electrical Feed through
The Electrical Feed Through of the 1520 Case, and already sealed using the Acrylic Sealant
