Playing around with a 9-axis IMU for work, and data seemed a bit.. off. Turns out that:

• accelerometer, 2 bytes per axis, big-endian.
• gyroscope, 2 bytes per axis, big-endian.
• magnetometer, 2 bytes per axis, little-endian

I guess that's what it must feel like to accidentally walk out on the same side of a revolving door as you walked in...

Who designed that?

Who designed that?

These guys with the horribly slow loading website...
I assume that the actual sensors in the IMU are by different manufacturers, and that's just the way it came out. It's designed for as low powerconsumption as possible, so I guess they looked for the parts that fit these requirements best...

Imagine losing your rudder out at sea and sending out a distress call. And then the largest ocean-going wooden sailing ship in the world comes to your rescue. Or in the words of the sailors on the sailing boat: "This moment was very strange, and we wondered if we were dreaming. Where were we? What time period was it?"

"Ship on the horizon!"
Skipper takes binoculars and scans, does a double take, and after a while takes down the binoculars, turns to the crew and says:
"Uhm guys, that storm last night, err... is anybody of you familiar with the movie "final countdown"?"

Considering the poor maneuverability of such tall ships, its really an impressive achievement in seamanship to take a small yacht in tow. It really requires planning ahead for about half an hour since you can't tack upwind on near the yacht and setting the sails after each maneuver takes a few minutes.

Goetheborg of sweden actually has Diesel engines for port maneuvering (I think it's kind of the law in most ports). You can see what I think are the active cooling outlets pretty clearly in the first image of the article you posted.

The Incredible Story Of The Dambusters Raid

On the night of 16-17 May 1943, Wing Commander Guy Gibson led 617 Squadron of the Royal Air Force on an audacious bombing raid to destroy three dams in the Ruhr valley, the industrial heartland of Germany. The mission was codenamed Operation 'Chastise'.

The wreck of the Titanic has been digitally scanned and preserved, at impressive quality. You can even see tiny details, like the the serial number on the propeller.

Pretty interesting to see the stern in this way. It's such a mess that it can be hard to make sense of it as a whole from dive footage alone. Photogrammetry is awesome.

A tourist submarine went missing near the wreck of the Titanic yesterday. Thats pretty much a first I think, submarine tourism was very safe so far, despite the dangerous environment.

Communications went missing already 1:45 into the dive, which sounds pretty bad in my ears, since it could mean that power loss in the deep.

I think most submarine tourism has tended to be shallow-water tourism. At this depth, it's more akin to space tourism (cheaper than space tourism, but also possibly riskier).

But even for non-tourism, I'm not sure I've heard of fatal accidents involving research submersibles. Even in peacetime, military submarines have been involved in most/all fatal submarine mishaps I've ever heard of (at least after the initial development of the technology). This is probably because military subs account for most of the dive time of submarines worldwide.

I think the most public incident with such submarines was the Russian Priz accident way back in 2005, close enough to the Kursk accident to make news.

But for example, I completely missed that accident:

Went on a submarine a few times. Never felt that comfortable like in an aeroplane. I mean, you don't actually feel any movement in calm water. But it's wet and noisy. And if you look outside you realize that you are in a world you are not supposed to be. I always thought: if that porthole blows, or if the hull fails or if we lose electrical power, it's over I would say it is indeed more risky than flying or going into space.

 

[TheShuttleExperience]

There are articles in German newspapers regarding that submarine now. They include an interview with one of the first paying passengers, Arthur Loibl. He visitid the Titanic in 2021 (with the same pilot and specialist now missing). He says he wouldn't do it againt. Back then they were sitiing in the submarine already when the crew outside had to do a welding job due to technical problems...

Well, you could even pay me 250,000 USD, I wouldn't do it But damn, the more I think about what happened and what they expirience right now if they are still alive, it gives me creeping horrors Poor guys.

Looks like the hull never underwent a classic certification, because it wasn't mandatory....

Yeah. I think it is very likely something severe that happened during descent (maybe involving the hull). No communications or signal is a very bad sign I guess.

Yes, No voice communication or data can happen, but not the carrier signal Unless there was a blackout onboard. And if a blackout happened while they are above the Titanic: Perkele!

No comms are to be expected, not a mil-sub afterall equipped with the appropriate ELF comm equipment. It can only receive very short text messages from the main ship. It isn't tethered.

They use UQC, the standard for underwater communications. Its purely acoustic. Text messages is a new standard and not widespread yet.
