I live on an island where it is very difficult to source Nitrox.
However, oxygen is relatively easy to source on island, and I was reading Gary Gentile's Technical Diving Handbook, and he certainly implies that homebrew Nitrox is well within the skill set of most mortals (oxygen clean your cylinders, fill with 02 to desired partial pressure, go to LDS and top up with air, analyse gas before using), and that it used to be done pretty regularly by technical divers before Nitrox fills became widely available at your nearest LDS.
Of course that is fine on paper, but if I blow up the shed (particularly with me in it), I'll never hear the end of it from my wife. Does anyone have any experience of home brewing Nitrox? I only found one related post on SB ( http://www.scubaboard.com/forums/ask-dr-decompression/26363-nitrox-after-45-a-3.html ) and that was from 5 years back, but it certainly implied: "it's not difficult, but be very careful".
