Do you do anything else to the 3pin to make them waterproof? I.e. use grease?

I plan to go into detail about water proofing the bulkhead 3 pin connections in a future post as currently they are just mocked up and not finished. As far as water proofing the external connections, I’m exploring some simple design options and will hopefully find something that will do the trick.
I’ve had to switch gears back to looking deeper into the overall command structure for the controls, programing code strategy, ease of use and failsafes. This will dictate the final signal wiring layout.
Getting there slowly.

Great find! Thank you for sharing these links!

I have not posted any updates in a while but I assure you some progress has been tirelessly made between posts. Been working on this project from pre-dawn to dusk, everyday since the last post. The hardware updates were simpler and will try to post updates soon. The software updates have been a handful and have been taking up most of my time lately.
Mostly focused around getting a solid compatible Interrupt based communication link between the receiver and Arduino have been a main challenge. I need the data interrupts to the main program loop to be fast. I’ve optimized this in the latest software code build. But it has brought problems into other functions of the build. Hence my silence.

Okay this is a probably a waste of a post but screw it.
After beating my head against the wall for hours on end, day after day, writing multiple different coding strategies for the Arduino to interface quickly and accurately with 7 receiver input channels while not interrupting the main program loop, and keeping the program small, I finally nailed it! Holy hell I swear I was about to loose my beans trying to crack this problem.
Solution achieved just in time for Friday night. Now I can rest. Downs some whiskey while writing this. Hey I earned it.
Most of the code and information exchanging has been written for the overall main program that deals with the pressure sensors and laser range finders, gyros and so on. I had to stop work on that code until I could establish a rock solid communication with the damn receiver that wouldn’t overburdened and block the main code from updating.
Long story short. I win and can now move forward with the project. Will post updates when it’s worth sharing.

Testing for the bow piston trim tank of the hybrid ballast tank project. This code tests the inner and outer most limits set for the piston’s travel when in dive or surface mode. The distance is recorded by the Lidar sensors mounted at the rear of the cylinder. Also shown at the end of the video is the vent or blow function for the main ballast tank. Most of these functions will be automated in future code updates. This is just a demonstration of the manual override function.
