Diving Software Widget...ideas?

[Conor]

Hi all

As most of my softwar experience has been server side I have decided to have a look at doing a little client side work.

In order to learn C# I have started putting together a few little widgets and am finding that when I do diving ones I'm a bit more motivated (funny that).

So I have built a little dive calculator that does MOD, ppO2, EAD, Cylinder Airtime and SAC. I am starting to run out of ideas.

Do you guys have any ideas of some other common (recreational) diving calcs that I could add to expand it?

Don't worry, its just for fun

Hi, Ive always found working out my turn point in Bar usefull, particularly on a deco dive. Id like to know the turn point based upon a variable rule. Not always thrids, as this is really only appropriate for overhead environments. For example on a deep deco dive theres no way your back gass is going to be enough to do all your deco on, so thirds is no good, but the reserve should be user defined. Bit like MOD, some like 1.6, others 1.4

Couple of ideas:

A weight check tool - not a cylinder buoyancy calculator (those are already out there) but something that works out the weight of gas in your cylinders. e.g. something that could answer the question 'if I do my weight check with 100 bar, how much extra lead do I need to add to make sure I'm properly weighted with empty cylinders'. Input variables would be cylinder capacity, bar in cyls when doing weight check, type of gas used (unless air), lead used in weight check. Output would be the extra weight you need.

A little routine to calculate the 'rock bottom' cylinder pressure that you need to ascend at - ie sufficient remaining gas to get two heavily-breathing people to the surface (for rec stuff, next available gas source for tec I guess). That will obviously vary with depth, cylinder capacity, deco commitment (?) etc, so something that can do the calcs for any combination of variables you enter would be useful. EDIT: a bit like what Ainsley says above!

A 'twinset topup' application that tells you how much gas you will have when whipping into a twinset from a single. Like the one mentioned here: http://s3.invisionfree.com/Ocean_Ody...181&st=0&#last

These are things I've had occasion to work out by hand a few times, or have written crappy little spreadsheets to do. So it would be nice if someone produced a nice shiny package to do it...

GUI shell for ddPlan?

Have emailed you the spreadsheet.

seconded

save me reading the help files to work out how to use it

thanks very much
all the best

An update;

As of now it has the following calcs
ppO2/MOD (takes depth & EANx% gives ppO2 and EAD)
EAD/MOD (takes EANx% and ppO2 and gives MOD and EAD)
SAC (Takes cylinder vol, Pressure before, pressure after, average depth and dive time and gives SAC)
AirTime (takes Cylinder colume, pressure, SAC and Depth to give a dive time)
Gas Weight (takes Eanx%, cylinder vol, pressure and gives gas weight and surface volume).

Have also added a nice YD logo (assuming Mods don't object)

I'll keep adding some bits, and keep this thread updated, so if anyone wants to be my first tester then please let me know

Cheers

Conor
