[Eirik] wrote in to share the build log for the third iteration of his underwater ROV. The first two project were completed and tested (you may remember reading about it back in January), but both had issues that caused general failure. Most notably, the introduction of water where he didn’t want it. But this time around he seems to … Read the rest
[Byrel Mitchell] wrote in to share some details on this water glider which he has been working on with his classmates at the Nonlinear Autonomous Systems lab of Michigan Technological University.

While some very important parts have yet to be implemented, like … Read the rest
This fantastically huge housing was put together by [Ed Sauer]. He put it together using TIG welded 6061 aluminum for the body and machined the port mount out of 7075 aluminum. The lens port is a commercial unit from a housing manufacturer along with a few manual controls. He wrote up the build in this pdf.… Read the rest
Underwater camera housings work great – but they are prone to humidity, dirt and dust problems if you open them more often than needed.
