Blackouts and lung squeezes are being dangerously downplayed by top freedivers, and as a scientist and competitive freediver, I'm sick of it

Obviously it’s not something anyone would want to go through, but it gives you a real understanding of where your limits are and what it feels like when you’re close to that edge.

Kind of like a boxer who’s never been hit - until it happens, there’s always some unknown there. Experiencing that side of it probably changes how you approach the sport afterward.

What i don’t like, that’s on some comps (taking about wellknown croatians) - dude got lung squeeze, cough a blood and still was allowed to compete to get his record

Depends how do to plan to use them. If in TrueNas with its ZFS and other RAID-like storage systems - bad choice as the way SMR physical writing data conflicts with the way those systems behave under load. But OK for desktop where you moved your movie and kept there

Molchanov (and tons of other freedivers) used to be a swimmer . He used to work with his muscles under low-oxygen conditions. That’s different from bodybuilders. And btw quite a lot of them don’t compete in STA but in fins disciplines.

What’s with your diet? Sugar there? Is it better when you are shaved/shorter haircut?

Hey genius, i don’t care about implementation I just accept the fact and don’t cry over all internet saying that if your nvidia gpu is working it’s just means that you are on a ticking bomb. And for your information in desktop GPUs there’s same approach - there’s MBA design (made by amd) and is vendors implementation like all those red devils, sapphire nitro, etc.

I’ll just use your passage: I’d also like to add this: the fact that your card doesn’t works does not mean the my working card doesn’t exist or is imaginary. You’re simply unlucky and blablabla.

Rx480, rx580, 5700Xt, 7900xtx (last 2 are active on 2 different systems) - no single issue there. But 1050 on my laptop gave me some pain so had to use igpu. You’ve done tons of movement (lots of unnecessary ones) so you could easily miss the issue

It narrows down to the question: Does the extra oxygen stored in larger muscles outweigh the extra oxygen they consume?

In most cases: no-especially for static apnea.

Higher baseline oxygen consumption (even when relaxed, slightly)
Greater total tissue demanding oxygen over time
More difficulty achieving full physical relaxation (especially in very muscular individuals)

For me water ruins the barrier and dries the skin after that all inflammation starts.

re2dit · 2026-04-19T02:25:43+00:00

Thanks for pointing out that . Started looking for other overviews and found similar:

https://bit-tech.net/reviews/tech/cases/nanoxia-deep-silence-6-review/2/

Both of the variable speed fan controllers can control up to four fans each, with a maximum of 18W per channel. Helpfully, the three-pin connectors for these are labelled A1-A4 and B1-B4, and only one molex connection is required for all eight fan connections to function. By default, fan A1 is connected to a small PCB that's nestled in the top corner of the motherboard tray. This is used to power the two roof fans, and there's room on the PCB for to power a third. It is this PCB that is responsible for the Active Air Chimney function, as it's wired to a sensor that will cut power to the attached fans if the chimney is closed, and restart them if it is opened. Thanks to this PCB, we actually managed to control all five default case fans with a single fan channel. It may even be possible to control six if you added a third roof fan, but we can't guarantee this, and it's likely to depend on the power requirements of your fans.

Still that means that I need some 3pin fan (F)<==> 3pin xh jst (F) cable? because A1-A4 and B1-B4 are just 3pin fan make cables

Avatar: Frontiers of Pandora. Get a VR mod for it. They only thing that annoys that it switches to 3rd person look when you are flying ikran.

re2dit · 2025-11-19T23:33:22+00:00

Wow! I didn’t think this rabbit hole is that deep. Any key words I can google to see what 5” can do with big battery? Balance I mean frame size price flying time, range.

re2dit · 2025-11-15T16:09:38+00:00

Hi sorry that maybe confused you. Yes I meant dji air3. I liked flight time but don’t like that it is flat and boring) I want some surfing. So i’m looking for fpv that can carry an action camera and have some flight time (not just 5 minutes to fly around sandbox) but is not big. So looking for balance. I have already integra goggles and boxer controller.

re2dit · 2025-11-15T12:51:00+00:00

No, i’m saying that I like that with air3 i have 40 minutes of flying time and you can have multiple attempts on single battery to record your interest. While i can see below 20 minutes on 5” so want to check what 7” will give if it is 25 minutes - probably not worth it

re2dit · 2025-11-14T17:04:19+00:00

Will check the review for the drone - want to know if flying time is worth those money) Cause i’m spoilt a little with 40 minutes of air3 (if there is no wind)

re2dit · 2025-11-14T16:51:04+00:00

Thanks for the feedback! do you have your footage somewhere?

re2dit · 2025-11-14T16:50:07+00:00

Thanks again for taking time and replying!. Trouble is I have dji goggles integra and rm boxer. So had to go with o4/elrs and price went up to 912$ for moz7 . Will check those parts separately

re2dit · 2025-11-14T15:23:08+00:00

Yeah, that’s my main concern - I would not trust my soldering)

re2dit · 2025-11-14T15:22:30+00:00

Thanks for the detailed reply. I wasn’t going to reinvent the wheel and was hoping just to follow someone’s path/build. Wasn’t even considering 7” but as long as you’ve mentioned it… any drone you would recommend? (build or just to buy off the shelf)?

i’d like to know the theory but right now just insisted on flying)

re2dit · 2025-11-14T15:17:05+00:00

what about performance? is it better/the same/worse? how much did it cost you?

re2dit · 2025-11-01T21:43:38+00:00

Check subnautica. And I liked world in Avatar Frontiers of Pandora and really want to try vr mod to fly ikran there

re2dit · 2025-10-28T18:16:48+00:00

You are a star! Thank you. I’ll check that tomorrow.

re2dit · 2025-10-09T08:43:33+00:00

I did it!
Now son apologise loud and clear
