Default Real time IBU calculation

I mentioned this in the Android brewing software discussion, but I figured it warranted its own thread. IMHO, it'd be swell if there were real time IBU approximation incorporated into the hop addition section of (insert brewing software of choice). For sh*ts and giggles, I whipped up a Java app showing that it can be done. It's a pretty rough hack, but you'll get the idea. It decreases the actual volume and increases the SG based on a user defined boil off rate and pre-boil volume/SG. The IBU calculation is based on actual volume/SG at each update.


The actual utility of such a feature may be somewhat limited, but I find it fascinating to see how the wort changes over time.

Geek.

Sorry, couldn't help it. I imagine there are plenty of people who are into the science of brewing who would enjoy something like that.

...and I guess I'm the only one fascinated by it. Eh, just an idea.

Yuri , we should share code and integrate it into the android app. I have made some progress on the droid app, and it is java of course.

I'll see if I can clean up the event handler portion of the code (where all the work is done) and post it this weekend.

The way I see it, this should be a configurable hop/boil timer that just has the added bonus of real time SG/volume/IBU approximation.

I have so many ideas for this junk I could go crazy. Wish I wasn't working on like 10 projects at once. Thanks Yuri. Are you also setup for android development? Do you use Eclipse?

I messed with the SDK once, but I've since removed it since I don't have an Android phone. I have an iPhone and have downloaded SDK from Apple, but I have so far refused to pay $99 for a license...makes me wish I'd waited for Android to mature just a little more.

I'm using NetBeans at the moment.

I have a g1 right now and not a mac, plus Java is my strongest language, so that's why I'm over in droid land. Before android and iphone were around, I did a bit of development for the Sidekick, which is also java. Anyways, I could use some help with this droid app - especially on the calculations and such, as I have been pretty Beersmith dependent and am a relative newbie with brewing. Anyway, a bit off topic for this thread!

I'll PM you my email address.
