Slowly pulling together bits and pieces to make a similar debreathing device to the one online. So far nothing restricted or expensive and I am in for @ 15 bucks.

Very interesting, NextBusLeaving. Are you willing to elaborate a little on what parts you're using, how it's put together, etc.? Do you plan to test it on yourself by seeing if it's capable of reducing the oxygen content of your breath and how quickly it does that?

I'm doing my best to try and resist ctb but you have my attention.

Can you post some photos? And give more detail?

At the moment theres nothing to post photos of except some shit in boxes lol. Looking at the design of the debreather it is basically two cartridges of soda lime with some pvc, a mask and some corrugated medical tubing. I have read up on various rebreather circuits as well as anesthesia rebreathing where gas is introduced and rebreathed. The fundamentals are there. So far I have acquired soda lime and some other pieces. I plan to test it myself SAFELY - basically not strapping the mask on to my face, just holding it up and removing if I get lightheaded or sitting in such a way that it falls - and it will, it will probably be somewhat heavy, 2-3 lbs so gravity safety is easy enough. I will try to update as I can. I have the important bits that needed the internet; now I just have to run to the hardware store and suss out some plumbing questions, i.e. diameters and what will make things mate up. But that's the bloody simple part.
The hard part is overcoming my crippling depression to get up off the couch. Today was awful after work. I just forced myself to take a shower + the dog out so I am up now.

That video folks are talking about.
Now it makes sense. I couldnt figure out where the counterlung figured In but the video explained/showed it.

Other collectors of things ppl dont want you to have: consider purchasing some soda lime now, while its out there. Sodasorb is one brand I found at @ $20/3 lb bag. A 100g amount will filter 23l of air. That is all

Do you mind if i ask which kind of product you mean (generally, not specific sources or sites)? I'm assuming you're talking about the 3-lb bags of straight soda lime? Seems like there's a variety of choices, including "discs" and some other mediums that are a little confusing.
Essentially any soda lime that can be used in breathing devices. Sodasorb was the brand I found on the big jungle river site. There are others. It looks like a cat litter basically. The bag said federal law requires a prescription, however I could find no relevant proof of that and divers use the shit too.
I am sure when the Debreather starts showing up with bodies attached it will become harder to get just like SN

Any info on handling? It's a caustic chemical, and it seems like it would require a lot more caution than SN. On the other hand, if it can ship through the mail, it can't be that toxic, can it?
Theres an MSDS. Mine came in a thick sack like flour and wrapped in plastic after that. No hazmat markings on outside of box. I will store it in my garage just like any other hazard...my SN for example.
Basically wear gloves and dont get it in your eyes. Seems pretty inert, hospitals use it. I wanted to snatch some early tbh.

A mega thread should be made on this once more info on how to go through with it can be acquired.

Sadly I don't think we can lay our hands on those sorts of chemicals in any quantity easily in the UK. It's kinda strange when I see YouTube videos where they will say "so I went to the hardware store and picked up a gallon of hydrogen peroxide etc etc..." It would be great if we did have those kinds of things available as I've tried to get my hands on things for projects in the past but they seem to be in very limited amounts of you can get them over here. Though I did once get some formic acid to make a CO generator. Lucky for me I could find the pure sulphuric acid as I would have probably botched it. I didn't know that the caustic gases would need to be scrubbed out. I would have probably melted my face off! ;-)
Thats so weird; i was seeing crazy amounts of stuff in Euros and Pounds which frustrated me because I am American lol

It seems like things are very different between the UK/Aus and the US. I can walk into a Home Depot and buy methanol, hydrogen peroxide, and probably enriched uranium by the gallon. Given how easy it is to get a gun here, nobody needs Home Depot to ctb (aside from ropes and such). But soda lime does look like it's more tightly restricted by sellers, even here. The one reason I can see it not being restricted further is that you need DIY skills to build a workable rebreather while you don't need much expertise to do a meto regimen and SN. Definitely not implausible that they'll try, though.

Hmmm maybe I've just been looking in the wrong places? I have needed to get peroxide to bleach plastic in the past but couldn't get it so easily. In the end I just got some hair dye products instead. Maybe it's just the things I've been looking for that are easy to find in America?
Its coming together nicely. So far I am into it about $80 however some of that is from testing and buying additional components to have on hand to experiment with, ie various diameters of pipe, check valves etc.
I am unsure of the legality of saying too much but I should be able to verify function with an inexpensive pulse oximeter which I have yet to acquire.

The uk is strict about most things though ,we cannot get anything hardly without either a prescription or jumping through loads of hoops .
Lucky we are allowed to breath lol
Surely a scuba diving store in the UK, or near by, would be able to help you find the substance as it's used by some divers.
I just verified it is available in England. Fwiw it is also used in aquariums for reef scrubbers to remove excess CO2.
I googled "soda lime in England" but I am sure other terms would work.
Also aquarium enthusiasts btw

Quite honestly i would not trust myself to build it correctly anyway
The final exit people seemed to have taken a long time to make sure the seal on your face stayed sealed once you pass out .
So i would not trust my own handy work lol .
I love the idea of the debreather. It's quite a simple machine, there just aren't any strip by step instructions on building one.
And that is what I am sussing out. ;) technology should be available to everyone.

That's cool! Well this is looking more doable. Would probably have to order online as I would probably not be able to speak the jargon to the staff in the store. It sounds daft but I have had times where I've gone into places buy something that I want to use to ctb and had the helpful member of staff suggest a "much better" alternative which I have bought in order not to rouse suspension!
What the FE folks have done is simply use readily available anesthesia/oxygen mask parts. Its really quite elegant in its simplicity.
I'm fairly certain that there isn't too much special about the mask they are using. It's standard medical supply stuff. The breakthrough for them was combining a mask with a adjustable seal (by filling the seal up with air) and the straps. I don't know for sure if they custom designed the straps or not, but I wouldn't be surprised if they were also available from the supply store. People who kill themselves aren't the only ones who need masks like that to stay on. The tubing could also be bought from the supply store.
The mask and straps arent even special. I have an identical mask as well as have found places where identical straps are sold. Its all off the shelf stuff imo
It's strange that Exit didn't give the debreather much surveying until a little stirring a few years ago and now, the soon to be released, plug and play
I figured as much, but at the same time it was the only part I could see holding them back from releasing the 'commercial' version sooner.

If keeping the simple face mask in place is a problem, can't a military surplus respirator be used ? should be simple enough to attach the debreather tubes to the inlet and exhaust valves once replaceable filter canisters are removed.
The old Soviet GP5 mask is readily available. It did not rely on elastic straps to hold it very securely in place, but was made of rubber which stretched over the full head. Not the most comfortable, but very secure.
