Hi, searching around I found at MSDN an example application that uses a devices built-in audio sensor to determine how loud it should ring. A very smart thing to do. The implementation is very basic, the app stays on forever so it consumer power unnecessarily. I wonder if somebody has written a better utility based on this idea.
Available at: http://msdn.microsoft.com/msdnmag/issues/07/10/NoiseDetection/default.aspx
That's a cool concept! Are you actually using that kind of app right now? And if so, where did you get it from?
I'm in need of a rangefinder, and was wondering, why not my always handy Leo?
Since it has a focusing function for the camera, it must have some sort of a sensor for measuring distance - or whatever algorithm it uses might be calibrated for actually displaying the(approximate) measured distance.
I would pay for a usable app.
Did a quick search of the Leo forum, no returns for "rangefinder".
Thanx
Cannot help you with a range finder tip, i don't think this is possible with a focusing camera, but why not google disto.

!! FUN APPLICATION, NOT INTENDED TO BE USED IN REAL WORLD AVIATION !!
For all those flight-sim enthusiasts out there: I have created this PFD (primary flight display) which shows the speed, the altitude the coards and the attitude similar to a real PFD display in an airplane cockpit.
Although the application has been created and tested on an HTC HD2, it might work on other devices as well. Internel or external GPS and the HTC G-Sensor are required. It is planned to add a serial communication channel to a PC server component which allows to use this little proggy with MS Flight Simulator displaying the flight parameters so you can get rid of the cockpit panel on your primary display.
Just keep in mind that this is the first version of the program, so there might be *some* improvement potential.
A screenshot of the program is also attached.
Pls let me know what you think about it.
Thanks.
As a pilot I cannot find any sense in this, sorry m8.
Useless for aviation.
Useful might be an HSI-App, an RAIM-availability-check-App, a NOTAM-APP and so on. An artificial horizon on a handheld device... No, not good...
Title correction...
It is just for fun, not intended for real world aviation.
I will change the title so that it becomes more clear.
As an airbus pilot I like it! Lots of scope for further development, keep up the good work !
when I read your discrip, I had something totaly dif pictured in my mind. guess Im falling back on my sail plane lesson days.
I had round face dial and a yaw bubble pictured.
While this is cool, I would prefer to see the old analog style with an altimeter that you can set your start altitude and a yaw bubble, rather than the HUD style. just IMO.
And yes this is just for fun.
Keep it up, I will follow your project with intrest.
cheers
Good Work mate
While some are critical in their opinion I'm pleased with your app.
Keep up the good work mate and for all others who are not so encouraging ...... what do you want for an app a full blown flight simulator, the guys making an effort to develop something and sharing it for a free with us so to help him out at least .... I mean at least encourage him and make some constructive criticisms.
It doesn't cost to be nice and help to motivate others...........
Customize it
Just as a hint for those of you, who would want to use other bitmaps. I have designed the application in a way which allows you to modify or extend it. If you look into the applications program folder, you will find an XML file describing the layout of the display. You may also change or add bitmaps. The bitmaps are all located in the
HTML:
resources
subfolder. If you change the size of the offset of bitmaps, you will have to adjust some values in the XML file as well.
As you can see there all items are drawn in 3d space.
However, I am working on a HSI as suggested before. I will post it later this week.
Known issue:
- After running the application 3 or 4 times, OpenGL is not working properly anymore (not able to create rendering context). This is an issue of OpenGL. You have to restart your device for OpenGL to work again. If anyone has a solution, please let me know.

That would be awesome!
Cool app
Certainly would be better than no attitude information in the event of a vacuum and/or elec failure.Even if just to make flying the performance instruments a bit easier.
I would defintely like to see a HSI app possibly with an open (editable)waypoint database.Anyone interested!?
Keep up the good work!
I love it. Thanks so much...
I just wonder if settings could be made permanent until being changed again so as to start the application without my having to select REAL and AVERAGE everytime.
And as a proud HTC HD2 owner, the display could me made much
larger indeed...
Congratulations and thanks again.
This is a fine app with a lot of potential esp. for UL-pilots as an emergency backup if UL-airplane-pfd fails.
Would be nice if indicators are bigger and the layout equals to Flymap, Skymap or MGL-layout
There is enough place for a nice big yaw indicator. Maybe You can get some code from GPS-tracker V2.0 (MooNah) in this forum, it already has a full working PFD incorporated.
Good luck with further devs., when next version is online I will try it in my gyroplane.
I think it's fun!!!!!
next step: build a flightsim for wm where we could use this
You will be in real danger....if you do so.

As you will easily see, this PFD horizon responds to gravity, that is, to the accelerometers installed in the phone.
It has no gyros, no way to provide PITCH ATTITUDE, WHATSOEVER.
If you keep the phone perfectly vertical and quickly move forward (accelerate) it will SURELY show a pitch up...pretty much the same effects that a stand-by compass shows when changing speed (remember that?...accelerate-north, decelerate-south).
You will have the very same pitch information as the one given by a bottle full
af water suspended from a string, or a can of Coke : and it will KILL YOU as well as your passengers (if any), not to mention people on the ground.
The only usable parts of this FUN APP (as named by the author himself ) in aviation are:
1. True track (not magnetic heading).
2. Altitude (neither QNH, nor QFE related, but of course; unless your flying field happens to be at sea level and actual atmosphere matches the ISA atmosphere parameters exactly). Remember that QNH variations as well as heat will make the GPS readings very different to that of your altimeter, as height of the air column will vary a +/-4% every +/-10 degrees Celsius.
Example. Airplane flying at Flight Level 300. QNH in the area 1023. Terrain at 2000 feet. Atmosphere is ISA+15.
Therefore if we move the 1013.25 setting to 1023 there will be a reading increase from 30.000 feet to 30300 (calibrated altitude, QNH related).
That is 28.300 feet above ground (we start with this as the air column height for the calculation). Since ISA is +15 we add 15/10 times 4% and we have 28300*15/10*4/100= 1698. True altitude is 30300+1698=31988
So we are cruising at FL300, 30.000 feet pressure altitude, 30.300 feet calibrated altitude (QNH related), 31988 above sea level, 29988 feet above ground level.
GPS WILL SHOW 31988 FEET.
3. Ground speed ( neither IAS nor CAS nor EAS nor TAS), as provided by GPS system. Remember that your airplane aerodynamics are related to calibrated speeds....you will stall if too slow ore destroy the airframe if to quick !!!! But you can navigate and make good your track, of course.
Hope I have made myself understood....and that you read this at the earlier !!!
Hi!
It quite very good if the second part under we have the route. I am using the Oziexplore program, it can creates the route, and apear on screen. if this soft applied to that once, could be perfected!
Thanks
great app mate..just for fun...
Nice work thank you. On future can you make like pilot cocpit with all dash boards like in Flith simulator game if this possible. Thank you

Indeed as an Ultralight-Gyroplane-Pilot I like this app and since the Horizon-tab in GPS-Tracker by MooNah doesn´t work right now this could be alternative as a a last resort-backup if glass-cockpit instruments (MGL-Avionics) fail ...... (better to have this than nothing at all and I also have Flymap PPC on my HD2 if main Moving map Nav. fails)
This app has great potential since it reads the infos from G-sensor and GPS.
For the future dev. if I might add my wishlist:
1. Add to screen: slide-indicator and compass, Altitude
2. slightly more refined graphics
As a start: BRAVO, hope You have the patience to go on developing this nice app ( like Dunc001, that made in 100s of hours of work a professional weather app - Duncans Weather Panel - see there - that is more reliable than many professional aviation weather briefings).
I bookmarked this thread and hope for further developments by U
Congratulations

This App goes in the right direction, but unfortunately not to use without Gyro in a Plane, but a nice game for pilots ;-)
Happy Landings
I know I could survive without an automatic profiles app, but I have a lazy addiction to them. The only problem is, they devour your battery.
I discovered "Easy Profiles" on the market, and it has outstanding reviews. Can anyone who is familiar with both Tasker and EasyProfiles tell me if there is a difference in battery consumption?
I'm not talking about how you can use these apps to decrease battery drain, im talking about how much battery the actual app uses while doing what its doing (polling for location, app launches, gps, etc)
i know that in tasker you can control how often it polls for certain things, but im paranoid that it still polls for things that i have no profiles setup for, hence potentially using unnecessary battery.
can anyone give me an overview on how these apps work in terms of battery consumption, and which one seems to use less to do its thing?
PS - i realize that battery consumption is relative to what you are doing....so please describe battery consumption based on YOUR use (i.e. if you used both tasker and easyprofiles for the same exact things, but one or the other seemed to chew less battery)
Thanks ahead!!
-Top
I am also choosing between this two apps, does anyone have experiense of this two?
/Mike
Perhaps a little late to the discussion, but I use both Tasker & EasyProfiles..
I originally used Tasker to control my profiles, but as rich as Tasker is in features I just wasn't happy with it as a profile app..
I tried quite a few profile apps and wasn't overjoyed with any of them - In my case, I wanted the option of profiles being triggered by cell tower id only and EP was the only prog I could find that gave that option. Installed the trial and purchased the full version the next day since it was exactly what I was after.
I've dialled back what I use Tasker for, but I still use it (in conjunction with EasyProfiles).
If your main focus is on profiles, then I'd go with EasyProfiles (it does a lot more than just profiles and it's kind of a mini-Tasker)
If your main focus is on automation, then I'd go with Tasker.
Both Tasker and EasyProfiles are extremely configurable which has the downside of meaning that both have a bit of a learning curve to get around. Tasker has online resources to help with that (doco, the wiki which includes sample tasks), whereas with EasyProfiles you only have the documentation listed on the website.
Personally if I had to pick one or the other, my focus is more on getting the profile functions that I miss from ye olde Nokia smartphone days so I'd choose EP as it does profiles really well, plus has a crapload of additional features that go well beyond your typical profile app.
Full disclosure: I'm a beta tester for EasyProfiles
Thanks
/Mike
Hi,
I started to use EasyProfiles two weeks ago (free trial period) and will get the pro version now.
I am also a bit paranoid about battery consumption indeed, and sure, it will drain battery on certain observation actions. I think that's obvious.
But what I liked about EP ist the fact, that it has in deep explanations how certain events are triggeres based on the battery consumption. You have a lot of settings to manually interfere with the duration and repetition period of battery draining processed.
E.g. you can set how often to check (switch on/off) Bluetooth for a headset or a car.
Or how often to check location and how (GSM sender based or WLAN or GPS based)
Also it has in the latest version (which I just downloaded yesterday and did not test yet) a finer model of activation rules "read-steady-go" where you can define rules which test on the first hand only for e.g. beeing in one profile (no extra battery), testing for another event befor testing for the real "fireing" event.
Thus allowing to choose a pre event which does not need battery and do the reguarly check for e.g. Bluetooth only if needed.
It's not that easy to configure everything but I like it and have built up quite a decision tree for leavong home, checking for car, reach work etc.
Using "hidden" intermediate profiles you can fine tune your battery consumption for event checking a lot.
I still see some increase in battery usage, but it from my feeling in the range from what I would expect from the regular checks I installed.
The bluetooth checks do need a lot of battery of course
I admit that I have no experience whatsofar from Tasker.
Hope that helps a bit
Cheers

I never liked EasyProfiles, Tasker, Locale, Llama Profile -Yes I know I tried a lot of different sound apps.
With those aps I had to reset my HTC Desire X many times. :crying:
The one I love is Smart Volume Control+
I hasn't interfered with the working of my phone at all. Just compare their reviews to the others. More people are happier with them.

How long have you been using Smart Volume Control+? Is it easy to use? I know some of the other audio managers have a learning curve with them.

What happened to EasyProfiles?

No idea - dev stopped updating and it worked ok for a while but then little bits started to not work as expected as Android marched on and EP wasn't updated to follow.
Really a shame - it was a great app.
I have managed to create some basic Android apps for myself, and have development expericence, but would like to know if anyone knows of a (preferably free) OCR library/class for Android. I'm thinking 2.6+ but I don't mind if it's 4.0+. At this stage it's just for my own use.
Some background - I have a device which displays and controls the current temperature of my pottery kiln. A picture of it is attached. It displays the current temperature (in red) and set temperature (in green) of the kiln, and turns the kiln on/off via a contactor according to a temperature ramp I set.
What I want to do is to log the temperature of the kiln over the whole firing (8 to 10+ hours or so). I currently do this manually, but it's a pain to go out to the kiln every hour or so, plus the time resolution isn't that great.
I had the idea of doing a time lapse recording on my phone using LapseIt, but I'd have to manually look at each image captured and enter in the temperatures into a list or spreadsheet etc.
So, I'd like to be able to leave my phone (Samsung Galaxy S2) in front of the device, and photograph and OCR the display every 10 minutes or so. This can then be saved to a CSV or similar on the phone for later analysis.
I have the foundations for such an application, in that the graphing, CSV saving/editing, are all in place, but I'm stuck at the OCR point.
Ideally what I'd like to do is to just call an OCR function, and receive text back, e.g. it could return "1022 1080" and then I can easily grab the changing temperature.
I can't find any such library though - this is what I need help with. Does anyone know of suitable library, or at least one that will allow me to OCR the image somehow?
Hope I have explained this clearly,
