The controller itself is probably reliable enough, like any cheap keyboard on amazon. I wouldn't want my life to rely on bluetooth though.
Absolutely. The fella in the article is going wired though by the look of it.

The article mentions that this gamepad was released in 2010, but also it's just a slight iteration on Logitech's Wireless RumblePad 2, a wireless version of the RumblePad 2 released around 2004. The newer models just add X-input, change the button faces from 1234 to ABXY, and made the wireless receiver smaller.
I still have my rumblepad 2, it is a fine controller. Why they would use wireless here is beyond me however.

I personally believe using mass market makes sense. I don't understand the criticism I've seen on this website for using off the shelf controllers or camping lights (what do you expect, an LED strip magically engineered by a large aeronautics firm specifically for the sub? and what would that change?). That being said, the difference between a Microsoft controller and a third party is that Microsoft very certainly di…
Logitech has orders of magnitude more experience in manufacturing peripherals than Microsoft. That said, Logitech does make products in a wide price range and the low end isn't competitive with their own high end.

At those pressures I don't think you would want to open the door even if you could. I was more thinking about being at the surface and having nobody else to unbolt it from the outside.
Oh yes, I am (though I am absolutely not a real engineer nor do I have any experience with subs) just questioning why they would need to bolt it from the outside anyways. If it was to keep occupants in, I would imagine that a door that opens outwards would solve that issue if submerged, and would still be openable on the surface

The Xbox controllers are used to control the periscope which is not a safety critical device. Regardless, the navy uses wired controllers and did extensive testing and verification. This outfit didn't do anything like that; in one video with a journalist the bluetooth controller was a 'feature' because they could pass it around the sub.

#187The fact that it's wireless is the scariest part to me. What if it runs out of battery? What if it desyncs?
They have multiple of them on board and can swap in a new one if there's an issue. The focus on the controller is misplaced to me. Game controllers are well made and better suited for the job than custom hardware. It's just the association with videogames that makes it seem odd. If they used $30 logitech keyboard as well, would anyone question that?

#188I'd easily take the bet that this controller was not the problem.

#189Why is a submarine going missing such a big deal? I am either growing old and grumpy faster than I thought or the media is in shambles.

Yes, if one had the budget to do all those things, from scratch, better than an existing component manufacturer. Not many companies have NASA levels of "throw money at it until it works, and every part has been signed off on five times." Absent that, I'm having trouble seeing how custom > COTS. In all probability, anything in-house would have been worse and added new failure modes. Better to buy, analyze, and adapt a…
They were charging a quarter million per head. Budget should not have been a concern.
