Hahahaha,… it is sooo funny to read all the “dangerous” bits of the comments… think about it and build one yourself… and than what? put it on the shelf and stare at it? you need to have a rebreather to use it – simple as that, and if you have one you will know what and how to do it. So lets nature do its own natural selection of peoples that will manufacture that rather good looking piece of scrubber and dive with it without rebreather LOL.

All right everyone 1st off try to understand what you are reading about, and how it works. This is a CO2 scrubber filter.The filter he built was made to replace the existing filter in a $10,000 rebreather.”Question being why not buy one after spending that much on the rebreather” But hey some people have the money to spend. I am truly disappointed by a lot of the “smart people” here. Most of your arguments not to make this are without anything to back them up other than narrow minded opinions. The filter in the scrubber does not have to be water tight “the housing it resides in does”, however do not get it wet unless you want to seriously reduce it’s life,maybe even yours. Dangers of making a faulty scrubber filter include,”Break Through” when it allows too much co2 to pass,or “caustic cocktail” if using sodalime, when sodalime is mixed with water releases caustics “not good to breathe”,among others. My advice is build at your own risk, and if you are going to comment on something try to have some knowledge of the subject before sharing your ignorance with the world.

People are responsible for their own actions. If someone constructs and\or uses something irresponsibly, based on limited, incorrect or misunderstood information, that person is willingly taking a risk by failing to research more thoroughly. That’s their right and good luck to them. What we absolutely shouldn’t do is withhold valid information in an attempt to protect such people, especially when more information is precisely what might prevent them from making dangerous mistakes.

Has our culture become such a blame&litigation-frenzy that people are no longer responsible for their own decisions? We take our lives into our hands every time we walk out the front door. Everyone has a different take on what constitutes a good idea or an acceptable risk. All we can reasonably do is discuss and spread as much knowledge and wisdom as we can, as best we can, and simply let other people be themselves and face the consequences of their actions. Such is life.

Not bothering to read half the responses here but those complaining at the top that this is dangerous… well I don’t see anyone running out and dropping 5000 usd minimum to try this hack. a rebreather costs at least that much. If you happen to already have a rebreather then you already know what you are doing and can make your own judgment about using this hack at home

Hi,

I am looking for ink cartridges for the Epson RX500. I have bought compatibles in the past but the ink quality is not so great or the chips dont recognise. Any help would be appreciated :)

in diving you learn to respect nature and your equipment and know the limitations. you prevent diasters by proper scheduled maintenance and rely on the instruments and backup equipment for safety.
if the rebreather refill is built to spec and carefully assembled, what’s to say that you can do it yourself. if the o2 level is too high you can switch to a pony bottle or use your buddy’s octupus…or do these things not come with a backup regulator. chances are you will get certified in rebreather diving and know how to stay within the limits.

I really gave it no thought until now. There is no readily apparent hold harmless statement here on hackaday. Perhaps they aren’t worth the bandwidth it takes to send them, I don’t know.

"Furthermore, it would seem stupid to modify anything your life depends upon; technical knowledge or not, scuba or otherwise."

Somebody had to do it originally. It's not as if being associated with a business automatically makes your work any good.

I have a feeling that most people who have access to a rebreather in the first place maybe know enough that this isn't such a huge deal.

Try to see if you find the data sheet for the co2 sensor, usually this is enough to figure things out.
Looked on digikey there was one http://rocky.digikey.com/weblib/Thermometrics/Web%20Data/AD81.pdf

Im building an indoor grow enviroment controller, using hobby robot parts, and a microcontroller. I cant find a DIY CO2 dectector board, or schematic. All the ones commercialy avail are for $200+, I just cant see why a guy cant locate the components, and build one. I did find a CO2 sensor,$6+ but cant find a circut to drive it. I was hoping that the scuba guy might know, if he is still around.

I think Hackaday has gone down hill from around a year ago.. wasn’t there a change over of writers?
