    I did some robotic submarine stuff in college. One of the techniques for waterproofing was put the electronics in a open at the top box and fill it with oil that was heavier than water. Messy but it worked.

      That’s absolutely genius. It’s like something out of troll science. “We soak it in heavier liquid to keep liquid out”. I’m a little awestruck.

      It’d probably stand up to pressure when deeper under water better than most other options too.

        Yeah you didn’t have a risk of pressure popping the seal and flooding the electronics. Also if there was a leak in the box you knew about it before you put it in the water.
