feels like they probably knew that in their heart the moment they see the $30 Logitech controller...
Using a game controller is not that unusual.
but it was wireless, that is bad.
What was the controller commanding btw?
The thrusters on the outside. The goal was to minimize hull penetrations for cabling and things.
Thank you, so the signal went through the water a little bit. We had a struggle about it in a different thread.
Probably not, actually. carbon fiber is opaque to blue tooth. Even a single ply carbon shell is enough to block it. My DLG r/c airplane uses an arramid section for the antenna.
Yeah. It's not unusual, for example:

I’ve heard of this. Out of curiosity (because I don’t actually know), do you know if the controllers used in military applications are literally “off the shelf” or if they’re “Xbox-like”, which is what most descriptions about them say.
In other words, I suspect the military(s) using these type of controllers are not just ordering them off Amazon and using them as-is, whereas it sounds like that’s exactly what OceanGate did.

There are "mil spec" controllers that look a lot like a game controller but have a ginormous screw on connector doodad.
I know the controller seems corny, but it turns out that even the US Navy have used Xbox controllers.
The real red flags here were the carbon fiber hull and the fact that the Titan wasn't even certified or properly tested to ensure it could survive the stress of repeated dives to such extreme depths.
It's kinda insane that OceanGate got away with taking paying tourists down in that thing for as long as they did.
It's a question of quality control. Military grade equipment is not the same as consumer grade equipment. That's why we have grade in the first place.
"Military grade" is not a statement of high-quality... it's a statement of specified minimum capabilities and characteristics to satisfy a contract. It's quite common for off the shelf commercial equipment, even stuff targeted at home consumers, to meet or exceed MIL-STDs.
What do you think quality means? Go pick some IC's and you will see that the best quality is kept for military grade operations like operations in very low temperature for example. An IC designed with a high swing in operational temperature will require much more thinking than a consumer IC.
Thanks for providing an example supporting what I said.
Cool...I'm glad that you understand better what quality means. Now if you have a different definition of quality that's a different story.
At least one of us does.
Well, sorry to disappoint you but if a circuit endures higher temperature swings than another then it is of a better quality than the other one. This attribute is part of the quantification of quality. But feel free to explain yourself.
"Military grade" does not necessarily mean higher quality. It just means it meets the requirements of the military for a specific purpose. Could actually be pretty shit quality. But you'd already know that if you had read RoboRay's initial comment.
To be fair the Xbox controllers are probably more reliable.
I believe the Navy uses xbox controllers for controlling periscopes, not the entire submarine.
Yeah, it wasn't the video game controller that failed...
