Found out a few months ago that my first real dive buddy passed away. I knew he was having some kind of odd medical issues but though he would get through them. When I first got certified in Virginia Beach back in 2005ish, I started posting here on SB. I only knew people far away that dove and...

I brought this up to my friend Robb R. down in Florida not too long ago. I am a computer guy by day and a bit familiar with this stuff. I repair vintage computers and arcades and stuff as a hobby and fall into the data hoarder side. Does anyone have credentials to the site outside of the owner...

Neat sensors! Seems similar to other ones that have existed. Looking at the command protocol it's basically 19200bps serial on a 3.3v serial bus. Doesn't seem ideal versus SPI or I2C. Could easily find a microcontroller that supports 2 or 3 uarts, the ability to read the DC battery voltage and...

I wonder if the systems send out data immediately when it detects hull anomalies along with auto triggering ballast drop. That would be how they knew. I think somewhere it was said that the support ship received a mayday? Also, I assume that all this chatter that is coming out now about...

It was strange because people watching the AIS locator beacons from the ships could see them running search patterns up until ROVs arrived. Maybe just looking for the wreckage with sidescan but looked like they were still looking.

How much more expensive would it have been to make the carbon fiber part out of titanium like the endcaps? Or weight becomes issue?

The company probably has more debt than assets? Also, the waiver they signed probably says all sales final.

L Like “accidents and incidents” where some people know the deets and let you know they know, but don’t deliver the info. Except good guy Cameron delivers.

After the video with the ceo talking about there being a hydraulic pump inside that could be used to actuate the release of the ballasts, I am betting that there was nothing penetrating through the carbon fiber tube but there was ports through the titanium endcaps. He shows where electronic...

My guess is the CEO was charismatic and able to instill false confidence.

Why wouldn’t you build one of these, tether it by cable and just run it through 200+ unmanned remote operated cycles from depths to surface and such to test it. As far as tech goes, a ROV with 360 degree active Hd cameras and either a high res VR headset or a dome paneled in curved high pitch...

Some articles talk like nothing goes through the outside walls of the people chamber, but this video describes a hydraulic operated pump that drops weights. Also a 10k psi tank that fills a lift bag. This is a pretty good video, I'm going to check out his others.

WIthout power they are all frozen by this time, no?

Now *THATS* a sub! I bet it has two rackmount TVs in the bathroom even. It could use some leather seats instead of sitting on the batteries in the middle or whatever those are.

They claim to have built a monitoring system to detect stress issues in the hull so they can abort. Assuming their onboard PC isn't stuck in a Windows update loop. Also without power there is no heat. I would assume they would freeze first. Plus no food. They could eat each other, but no way to...

Make an air tank out of the composites the sub is made out of, pump it up to 10k psi?

In the one document it made it sound like the human compartment is a solid composite thing with no holes or ports through it except for the viewing port. They screw it on before it goes down, and sounds like there is no way for occupants to open the hatch nor one of those valves for ambient air...

The awkward look around at your coworkers when your boss probably isn't coming back. Now what?
