[APP]Waterlevel 0.2 (Another waterlevel application!)

Wiebbe · Jul 26, 2008

Well, there are already a couple of applications out there already, but i was playing with the SDK and just trying some stuff out in visual studio so i thought, why dont i just release it?

Its a first release, it does work, has some basic calibration and im trying to make a bit more visually appealing that just some bars

So,

version 0.2:

- Updated graphics of the "Circle" compass/meter. Now actually looks like a compass thingy

- Added the ability to actually save the calibration data, and to let you know its doing something and its done.
- Created an CAB Installer to install the addon.
- Made all pictures internal resources.

version 0.1:

shows an Water level for the X and Y Axis, an circle "meter" and an light meter. There arent any big bugs that i know off, but i didnt implement the "maximal" meter bars yet. That means the measure bars can go a bit beyond the container

Requirements:

You do need the Compact framework 2.0, it will (unfortunatly) not work without it! But seeing as everyone already has the lightsaber application i guess its not that much of an issue

Other:

If anyone has some suggestions or comments (bad or good..) just let me know..

Source:

I added the source code if anyone is interested. Its not some good code, and the calibration could be alot more detailed, but perhaps it helps someone

Oh, and if anyone reflects the application and starts to rant about how my code sucks, i didnt optimize it or plan ahead, i just started to code some

1. congrats and keep the good work! it is refreshing to see a newbie that brings something to the forum and don't start with a wining post.
2. i really hope you'll receive only positive feed back (not so common here

) and allow me to be the first one to say: no, i don't think yr code sucks

3. is the calibration function working?
4. can you explain what "lumens" are doing here. lumens is an international measure unit for light. are u trying to use the internal light sensor to measure the light? this could be a good idea and i'll be very interested.

hallatore · Jul 26, 2008

Lumens is the light sensor =)

Awesome app, calibration works perfectly and saves the setting ok and that light sensor is a nice addon.

Would love to see this made into a .cab installation and perhaps make this app work with the AppToDate program for easy updates.

Look forward to future updates

This is going in my favourite apps

Ignore my double post

KukurikU · Jul 26, 2008

awesome it is! great app.
explain please what is with light measuring pls....only measuring or calibrating the automatic light level also?
thanks!!!

Wiebbe · Jul 26, 2008

No, it measures the amount of light the light sensor receives. I will eventually add an cab installer, but seeing as its still in the "works" i am not bothering with it yet

The calibration works, its not as awesome as the BubbleLevel one yet. When you press the button let the diamond lay there for 3 seconds, and then it calibrates. I wont update the backlight.

The light sensor only shows the value, it doesnt update the backlight it self. I tried doing that, but i can only turn the backlight on very bright, very dim and off. Not somewhere in between

Calibration

Nice app! I like the light sensor also, i finally found out where the light sensor really is

It calibrates fine but does it actually saves it somewhere? the moment i close the app and start Teeter, still not calibrated.

So far non of the apps around here were able (for me) to save the calibration. Some people mentioned success though and since I have tried by now all available roms and on none the calibration works, i get this idea that there are several versions of the sensor (hardware) around...

Anyhow, good to see a new app like this and success with it!

Wiebbe · Jul 26, 2008

No, the calibration it not saved yet, i will add that soon. The problem with the calibration data is that its reset on reboot. The only tool that i know of comes from a different telephone (Raphael or something) and does save the calibration. But not all roms work with this.

So the calibration from almost all applications will only work on the application itself

Kisja · Jul 26, 2008

Wow, thats the best waterlevel prog here around! Nice graphics, but still very simple. And the lights measurment is very nice too!

Very good work! Thanks!

KukurikU · Jul 26, 2008

icon maybe?

Wiebbe · Jul 26, 2008

I updated te first post with version 0.2. I added some more graphics (lightmeter still had to be done

) an saving of the calibration data for this app only.

@ KukurikU:

Well, i created a simple icon. I tend to like simple stuff that easily identifies a software app..

KukurikU · Jul 26, 2008

i put my diamond on a real level meter, bring the level meter to 0,0,0 and pressed "calibrate" and now i can use my diamond as a level meter.

....until next reset..

Thanks Wiebbe, nice little app. Will be very useful with my missile launcher!

uniqueboy · Jul 26, 2008

Accuracy is a little off, well a lot off, on vertical measurements, try to get it to read 90 degrees, could this be an issue with the G sensor itself?

hard to tell who is to blame. look at the experiment/calibrate method described in my previous post.
i found my diamond to be "off" by 1.4-2 degrees (am i lucky or what?!) and after calibration 0,0 it stayed this way after playing with it quite a bit.
edit: sorry, my bad, now i get it...you r right, on vertical about 7 degrees off... getting 97-96 degrees.

Wiebbe · Jul 26, 2008

Well, its not that the accuracy is really off. The SDK returns a certain value and its kinda hard to precisely convert it

Ill see what i can do, working on a different way to calculate the angle now.

edit:

Its odd, when i place the diamond vertically against a flat surface (whick should be 90 degrees) the build in Angle says 98 (from the raw data) my calculated one says 92. so its hard to decide which one is correct

After some more testing, it seems that all other applications have the same "error". Bubblelevel says 97 degrees as well when i place it against an 90 degree angle object. Same goes for SpiritLevel. I made a new way to calculate it which seems to be more "accurate" with the angles. But it still wont be 100%! Well, the number of degrees isnt 100% accurate, the bar it self ofcourse does work properly!

uniqueboy · Jul 26, 2008

Does the output from the G sensor give X,Y,Z or just X,Y ? That coul be a problem when measuring the vertical. If it's just X,Y then maybe when tipped past a certain threshold an error message should be given, or even an audible warning.

Wiebbe · Jul 26, 2008

The SDK in rawdata form gives back the following:

Angle for X
Angle for Y

Tilt value for Y
Tilt value for X
Tilt value for Z

The angle values are really in degrees, the same as SpiritLevel. They output around the same values as i output.

The tilt values are something from 0 till 1000+, you can see these in BubbleLevel as well at the calibration. I used the angles before, but these arent very correct.

Ill see if i can get myself a watermeter and an setting where i create an real 90 degrees setting so i can calculate a bit what the real values should be

It could be my house is like 97 degrees sloping, but i doubt that ^^

dont forget that an angle of 97 is possible if you tilt it above the 90 degrees value..
