Scuba Forum / UK Scuba / January 2005Mixing Gas
Hi I'm planning on writing a program that will take the hard work out of calculating gas mixing Some of the features I intend to build into the program would be allowing the user to enter their own personal preferences (regarding PO2's and narcosis depths for instance), and a facility for calculating what you have after an air top off I intend to make this a customisable program, so to look at the air top off feature for instance, the user could input the maximum narcosis they wanted, and have to suffer less pressure, or input the pressure they needed and decide if the resultant narcosis is OK I also will probably let it build a database so centers could use it to log the fills they do If anyone is interested, I would appreciate suggestions as to what the technical diving community would like to see in such a program Although a fairly straight forward proceedure, I don't want to include a facility to produce a table, this is more to do with any liability issues rather than program design Also, I intend to write this to run on a Windows platform, If there is a requirment for it to run on UNIX or a Mac, then I'd be interested to know TIA mikew >Hi > >I'm planning on writing a program that will take the hard work out of >calculating gas mixing Snipped >Also, I intend to write this to run on a Windows platform, If there is a >requirment for it to run on UNIX or a Mac, then I'd be interested to know Oh, you mean like http://www.combro.co.uk/nigelh/ Pete S. www.derwentelec.clara.co.uk >> I'm planning on writing a program that will take the hard work out of >> calculating gas mixing > > Oh, you mean like http://www.combro.co.uk/nigelh/ Wooo. Has Frank been leaving his nasty pills about? I haven't done anything quite like that. I just do blending with some twiddles for EAD and END. I only put 'top off' on the IPAQ version. nigelH http://www.nigelhewitt.co.uk/diving/windows.html > >> I'm planning on writing a program that will take the hard work out of > >> calculating gas mixing [quoted text clipped - 9 lines] > nigelH > http://www.nigelhewitt.co.uk/diving/windows.html Thanks for that Nigel, nice to have had a positive comment I think I'll do it anyway It will be a way of getting back into seriouse diving When it's done is there any chance you could have a quick look at it It will probably be a bit of a tinker toy for myself so I can't say when it will be ready Thanks as well Zak for taking the time to reply sensibly I'd also be interested to see the application Pete S has produced But I'd really appreciate it if he could leave Franks pills alone ;-) mikew >> >> I'm planning on writing a program that will take the hard work out of >> >> calculating gas mixing [quoted text clipped - 12 lines] >I'd also be interested to see the application Pete S has produced >But I'd really appreciate it if he could leave Franks pills alone ;-) My link merely pointed to the web page that Nigel had with his software on. I really don't understand the stuff about nasty pills. Pete S. www.derwentelec.clara.co.uk > Thanks for that Nigel, nice to have had a positive comment > > I think I'll do it anyway Do read Nigel's stuff about Van der Waals then. The ideal gas approximations are OK for people using calculators but if you are writing a dedicated blending program, there is really no excuse for not doing it properly. Tony > Wooo. Has Frank been leaving his nasty pills about? All natural baby, the result of dealing with - well those that know, know ;-) appologies to the rest of you (David) if I'm too direct, it saves confusion in the translations. In Petes' defence I did go round today. /F http://www.e-aquanauts.co.uk : More Toys than Gamleys' > Hi > > I'm planning on writing a program that will take the hard work out of > calculating gas mixing Almost everyone has written their own.... its a useful exercise, but dont expect to be able to sell it! > Hi > > I'm planning on writing a program that will take the hard work out of > calculating gas mixing <snipped> Lots of these available either for windows base, or for palm. In addition lots of others that I have on spreadsheets. Steve I've got GUE's Blender program, but nothing for my Palm. Is there something similar that will run on a Palm version 5 platform? How about IPAQ?

Is it just me sitting here with a mental image of Nigel bouncing up and down like an over-excited child? Is it just me who has a funny feeling that he might *actually* be bouncing up and down like an over-excited child? CAS >> Lee Bell wrote: >>> How about IPAQ?

Hey, Put the breather in a box and get up here. There is hardly any ice in the bay and we even have a boat in the water. The viz is fantastic and - well - it's bloody f*****g cold so the jumping up and down bit comes into good use... But do hurry. If the weather keeps like this it'll turn into an ice dive in the matter of hours. timo 60 deg north, 15 deg below Timo Ahom?ki wrote: > Put the breather in a box and get up here.

One day I'll be there again... This year I've already scheduled most of the big holidays. nigelH > I've got GUE's Blender program, but nothing for my Palm.

On palm I use Guy Wittig's program, I think his web page is at www.users.bigpond.com/wittig/mixer.html Steve > I've got GUE's Blender program, but nothing for my Palm.

There's something called 'Mixer' I've got on a Palm, fairly simple but it does the trick. - Keith > There's something called 'Mixer' I've got on a Palm, fairly > simple but it does the trick. That's the Guy Wittig program Keith, same one as I use. Steve |
