An update on the OFCOM situation: As you know, censorship around the world has been ramping up at an alarming pace. OFCOM, the UK’s communications regulator, has singled out our community, demanding compliance with their Online Safety Act despite our minimal UK presence. This is a blatant overreach, and they have been sending letters pressuring us to comply with their censorship agenda.
Our platform is already blocked by many UK ISPs, yet they continue their attempts to stifle free speech. Standing up to this kind of regulatory overreach requires lots of resources to maintain our infrastructure and fight back against these unjust demands. If you value our community and want to support us during this time, we would greatly appreciate any and all donations.
How many messages does it take to be eligible to start a conversation?
I already had reached that criteria, however; it shows that I'm not eligible since the data loss occurred.
There is no direct replacement, this is the only source. If you need it urgent you can achieve the same by stacking two adapters
which is not the preferred method.
I'm almost done with my setup. I just wanted to clarify that I don't need a flow gauge regulator on top of the scba regulator. From what I understand all that's needed is so attach the scba regulator to the cylinder (with an adapter). No need for a regulator like this one below to control the flow, the ldv does that automatically. Just wanted to make sure I've got that right.
Can someone please help me with sourcing a mask for SCB in Europe by sending a DM? I was going to use the eebd method, but the exhaust did not work properly in the hood.
Thank you for any help you can provide.

Air-to-Nitrogen adapter, DIN 477-1 No. 10 (W24.32) to DIN 477-1 No. 13 (G5/8").
This will be connected to the Nitrogen cylinder to be able to connect Air regulators.
Measurement of the adapter's width
Measurement of the regulator's width (more than enough to receive the adapter)
32mm spanner, the only tool needed
Flow restrictor for gas purity testing
O₂ testing **brands have not been removed because this can't be used to CTB, just to test the purity of a gas**
CO₂ testing
Tablet data, on-the-fly monitoring of: Time, O₂ saturation and heart rate
It's surprising that gasmonkey got his nitrogene cylinder from 4m4zon... I try to imagine how it was sended to him. O.o How can you make sure, that its purity is really 2.8 or above before buying? Are there any other reliable resources in germany or surrounding european countries?

Gasmonkey has helped me a lot but looks like he is having a well deserved break. Just want to summarise my steps and get some feedback:
Im using the SCBA system:
Confirm cylinder size and quantity (10l bottle is ample)
Confrim gas is pure (reputable retailers assurance is sufficient)
Confirm gas pressure
Sit down upright in a chair and strap your body. Be secure so that you won't fall over when black out. Do not lie down. A few final twitches are possible but convulsions are unlikely.
Put the mask on. Check to make sure its properly sealed.
Open the cylinder's valve.
Take a deep breath of air and hold your breath.
Insert the demand valve into the mask.
Hold breath and Pre-fill mask (pressing the front black button for 1 second). It pumps at 400 LPM when pressed full. If you press longer gas will simply flow through the mask escaping through the exhalation valve.
Insert wrists into the straps/ropes (not really necessary)
Exhale as completely as possible and empty your lungs
Take a deep breath of Nitrogen. Relax and breathe slowly, calmly and deeply. A lot of people don't notice anything, they just black out, but symptoms may include tingling in my hands, dizziness and disorientation (perhaps like a sports concussion), gray visions around the edges.
With SCBA you breathe a guaranteed 100% pure gas from the get-go with absolutely zero air/oxygen, the time to lose consciousness will be under 20 second with death to follow within 5-10 minutes.
Also, am I right in that the hood demands a constant flow of Nitrogen, but the SCBA mask via the demand value will only use enough nitrogen from the tank to maintain100% saturation?
So I open the cylnder and my SCBA will fill with 100% nitro. I will breathe out Co2 and the cylnder will replace it immediately.
When my breathing becomes shallow the mask will still maintain 100% full with nitro but do so slowly. Once Im dead and no longer expelling co2 the mask will be full with nitro but the cylnder will not be emptying.
Conversely, with the hood method the cylnder will be constantly emptying.
Is this accurate?
Gasmonkey said: "Yeah the demand valve maintains a positive pressure inside the mask, just using the necessary gas.|
