Can you record the data? It would be interesting to somehow coordinate (in-flight or later) with a GPS track. Presumably you are using an air-pressure sensor plugged in to the phone. Since it's a phone, maybe the locations of great lift and bad sink could be posted tot he web or sent to others with phones running appropriate apps. An evolving (near) real-time map of the day's conditions, perhaps.
This would mean I'd have to get one of those secure cases for my DroidX and figure out a mount...
If you get one for iPhones I'll beta test for you...
Find a "sexy" beep tone that's more soothing than pokin you in the ear.
Keep indicators BIG for the sight impaired.
Sell it cheap like an App.
Sorry, no iPhones... Objective C is not my strength. C, C++ & Java only
What beep do you like more? Sine, square or sawtooth? http://en.wikipedia.org/wiki/Waveform
I like BIG

That's phase 2.
I can log GGA NMEA sentences (taking the calculated altitude as hight) http://www.gpsinformation.org/dale/nmea.htm#GGA
Sorry but I'm against any form of radiation be it BT, WiFi or GSM. That's why I focused on a USB solution.
I love "Airplane mode" !
I guess it's a to turn off the phone at least while flying Land is full of zombies texting, browsing and messaging so why take it in the air?

Downside is that your phone has to power the device. The term is USB-Host.
You'll know it works if you can use a regular mouse or keyboard to control the phone... like here :

I'm working on a "native solution" as well to enable android phones with android 2.x to use the app - but you would need root in that case. _________________ "Men were not meant to leave the Earth.

This is great! Finally a real excuse to root my android phone and try some app coding.
The toradex sensor seems to only have windows drivers. Wondering how to interface it for a droid app written in java.
st1lgar, what is the sensor that you used ?
It's the Toradex
If you run ICS you have API for accessing USB devices but you still have to b able to power it...
If not, and that's what I'm working on for gingerbread devices, I ported the libusb, and libhid to android using the google NDK.
Then , with root access you can see the USB dvice in /dev/bus/usb/... What remains is to interface the C/C++ library with JNI calls from java . _________________ "Men were not meant to leave the Earth.

I just hope the Guild Navigators don't get wind of this.
Not if they have their spice... _________________ "Men were not meant to leave the Earth. Spend too much time in the clouds and you never want to come back down again.

I might need to calculate the mean altitude for a given period (1-3 sec) before I display it...

I was thinking to contribute to XCSoar _________________ "Men were not meant to leave the Earth. Spend too much time in the clouds and you never want to come back down again.

That would be excellent! We'd really like some help on the vario functionality (and improving the suitability of XCSoar for hang glider / paraglider pilots). The main XCSoar developers are all sailplane pilots without barometric sensors on their devices, so although there have been requests for audio vario functionality, nobody has the hardware to develop it nor the ability to compare the response in flight against other non-TE-compensated varios. Please ask on the forum, mailing list or IRC channel if you need help or feedback. (I can't post links, but if you check the 'Discover' link on xcsoar.org you can find those items.)
... and I don't have a HG vario to compare the thingamajingie to...

I've been on the xcsoar-devel list for a while now
Just didn't had anything to contribute to since recently ... and I'm familiarizing with the code.
Cool

What do you mean 'without barometric sensors on their devices'
The list is huge
Unfortunately most of those devices only give a pressure reading over NMEA every 1 second or less (intended only for use as a pressure altitude altimeter), it's only the latest Android devices with built in barometric pressure sensors, and presumably the Toradex, that give low level access to the sensor and allow fast & precise enough readings to generate an audio vario.

It might be worth begging someone to loan you one temporarily. Even if you're just comparing the two in the elevator it'll give some indication of the response rate. Unfortunately you may find the Toradex sensor is not as good as some of the latest devices (The best sensor I've seen is the MS5611, I don't know of any USB HID interface boards for it though)
I would like to check this out. Can you post or pm me with a link to the beta app? I have a little knowledge with Android app development and might be able to help with the UI. But mostly I am really excited about this idea as a vario, and would like to try it out... And I am really looking forward to you making it a part of XC Soar.
Have't touched the app since Friday. Busy at work...
As soon as I have something I'll let you know.
