zero point shift of spirit level or water level - Nexus 5X Q&A, Help & Troubleshooting

a) download any spirit level tool app from Play Store.
b) put your 5X on its left side down on a table. You need to be sure that table is horizontal with a physical spirit level or something else.
c) open the spirit level tool app you just download, that shows, in my case, about -2 degree. That table is flat and horizontal.
Is that a common case or it just me?
P.S. I've not test the gyroscope for I don't have a real compass.

Running (or walking ) GPS route recording

HI - first post so please excuse any errors - Does anyone know of any software for my HD that will record GPS positions over time ? (at regular intervals etc) - I do a lot of longer distance running and would be interested in carrying my HD for a run to record distance, speed etc from the GPS. Also for walks etc - which I can then analyse later (ie prob record GPS positions at set intervals etc)
Does anyone know any software that will do this for me please ?
I'm using trackr to record my bicycle rides; works like a charm. The only drawback is that you have to leave the screen on.
Another possibility is trip tracker sportsmate
yes they look great thanks - will give it a try
track your run/walk etc
try smartrunner from http://www.smartrunner.de
its german, but freeware and absolutly the best i´ve ever used....
and i´m running many kilometers a week ;-)
grtz

This recording of running around seems to be a German thing
you need a GPS program
I recommand: GPSmeter 5 or GPS Tuner
thnx all - will try them out
Try GPS Cycle computer, fantastis program and the schreen can be off

run.gps
Run.gps is incredible software. It is absolutely the best software I have on my phone. Heres a few of its features:
1. You can plan routes on google earth and export them to your phone. Then it will display the route on your phone and you can even tell it to read out the directions of the route during your run.
2. It logs the position of your run, which can be viewed in google earth after your run.
3. It can read out to you anything you want during your run. eg. I set mine to tell me my speed, average speed, distance to the end of the route and time to the end of the route every 2mins.
4. It saves all of your training plans - giving a report for distance run, calories burnt etc. You can view these in a weekly/monthly format to see how much you have been doing.
5. Screens are customisable. You may not want to view a live update on a map as you run, you may just want to see your speed, distance run, calories burnt etc...So you can set the screens up exactly how you want. Theres a function to keep the backlight on during use so you dont have to keep pressing the on button during your run.
6. It can be used for loads of other sports not just running.
7. Can be used for interval training and marathon training.
8. Buying the software gives you membership to a site where you can plan/ view your routes and other peoples. As well as view all your training plans.
9.The software is totally finger friendly.
10. You buy the software in a bundle with a 'tune belt' neoprene holder which is pretty good for the Touch HD.
Anyway, hope that helps - I really recommend the software and theres a free trial for a certain period. I tried it before I brought it.
Regards,
Richard

[APP][ALPHA] G Force Logger for Vehicle Performance (no, not gPC)

Hi, my name is Eric. I've been working with WinCE for a long time (since WinCE 2.0 haha) and I've regained interest in PPC programming. Working with few things here and there, mostly experimenting.
In anycase, I've got an idea to record g forces on a vehicle while it's being tested to its limits (AutoX, drag race).
Now, I know there's already a piece of software out there, gPC, but it isn't completely refined (indepth calibration, angle corrections) or completely free (by donation).
The goal of the project is to create something similar to a device called gTech which goes upwards of $300 for the basic model.
Key features will include:
- a reset function + algorithms to compensate for device orientation
- graphs of resulting logged data
- logging of calibrated data and raw data
- Driving aids
- Flashing screen to indicate reaching of new peak G (separate indicators for forward and lateral)
- a screen showing realtime overlapping graphed data for all axis
- a 2d grid with a cursor indicating current forward and lateral g
- on the same 2d graph, a drawn boundary indicating limits of g achieved (this will eventually look like an egg after working the car hard)
- and finally, real time telemetry transmission via edge/3g to a receiving computer
The ultimate goal of this project is to provide reliable data for motor enthusiasts whether they would like to see if their shifting is smooth, or if they're braking, or powering on in the right places or if their car mods have had any effect (this last one is pretty useful to quantify). In addition, provide some rudimentary tools to assist in competitions and spirited driving in the form of g limit warnings (flashing screen, large indicators of current g). In the case of spirited driving on a mountain road, the device can warn when approaching loss of traction (after collecting limit data) to prevent going off a cliff.
Venues of use:
Auto Cross
Track Days
Drag Strip
Skidpad
Of course, I have to insert here, that this device can't save your bacon if you do something idiotic and by no means do I condone dangerous driving.
With that said, all the above is what I hope to achieve and any of your comments is well appreciated.
Current Release:
v0.1
Alpha stage, rudimentary raw data output via numbers and a line (indicating X and Y recorded g) and a circle (indicating Z g). The numbers shown are the raw numbers recorded from the accelerometer and not converted to m/s^2. Although, you can probably do that math on your own if you're smart enough (simple scaling). What I've discovered is that each accelerometer is different, and even going from a negative axis (eg, device upside down) to positive axis (device right side up) will give different numbers. In addition, if you run the program, you'll notice a lot of jitteriness. I hope it doesn't affect the accuracy once I smooth them out with a segmented average.
Executable is packaged in a zip. It contains an EXE which can be straight run with Dot NET CF v2.0 (basically, all WM 6.1 devices)
Hi Canagan,
Great idea, I will certainly be testing this out.
I would like to ask, would it be possible to be able to include 1/4 mile time, and 0-60 etc so we can work out HP of the car. There is a similar app for the Iphone called Dynolicious http://gizmodo.com/5030749/iphone-apps-we-like-dynolicious-car-performance-meter
Thanks.
Whoooaaa sound a really good app ! Will test it this weekend ! Thanks

Yes, I can do that if there's more of a demand for it. Calculating horsepower is fairly simple, however, I may put 1/4 mile times and 0-60 towards the end of development as they require tieing into the GPS.
Great idea.. I will test it also
It seemt to be working on my Touch HD. But are the meaning of all these numbers??

Cool, looking forward to seeing this develop.
So far the accelerator test seems to be working fine.

Any way Alphablend API's hardware acceleration

I'm programming in VB.NET with CF 3.5, and I'm using alphablended images on a simple form. But when I'm put an image below a transparent part of another image, and I'm moving the first image, it's doesn't move, just when I'm refresh the parent of it. But for my sorry, in that way the image is blinking.
Any way to get hardware acceleration to the alphablending, to make it fast and smooth?
In the MSDN I read this:
"For Windows Embedded CE the AlphaBlend API does not require special display hardware, though it can use hardware acceleration if it is available. It can be supported in software."
Here:
http://msdn.microsoft.com/en-us/library/aa911228.aspx
I read the BitBlt uses hardware acceleration, but I can't use it on the Alphablended image.
I'm attached the custom control (created in C#), what I'm using to display alpha blended images. Maybe someone can upgrade it to use BitBlt, to use hardware acceleration.
Please help...
Anyone? Just a hint or something, please.
The situation is the same for BitBlt and AlphaBlend. Both can be hardware accelerated, but neither of them is guaranteed to be. On quite a few devices even BitBlt isn't hardware accelerated.
If you are AlphaBlending an image (TOP) over something else (BOTTOM), and you move the BOTTOM, you will get a "weird" result. This is perfectly normal and expected behaviour.
You have already seen that if you redraw the BOTTOM, and then redraw the TOP the result is fine - but may flicker.
This has nothing to do whatsoever with hardware acceleration - only that if it was really really fast (hardware acceleration or not) it would be too fast for you to see the flicker.
In this case you would need to use "double buffering" to prevent to flicker if using normal GDI ( = standard windows ) controls. Unfortunately on Windows Mobile double buffering is not (automatically) supported as with normal Windows computers.
So, you must either use a different display technology (like DirectDraw/3D or OpenGL ES) or implement the double buffering yourself.
Doing it yourself is not that difficult. Create your own control that holds both TOP and BOTTOM image. Then first draw BOTTOM to an internal bitmap, then AlphaBlend TOP on top of it. Only then draw the whole (resulting) image to the screen.
That bases is simple, though if you make your whole window this way it can quickly become complicated
I don't know if you found an answer,
but if you want to avoid flickering/blinking,
you must
- override the OnPaintBackground of the component with empty sub.
- avoid to clear a bitmap, it consumes a lot of time !
Let me know if it helps !

Need an application for determining object direction

I need something that will allow me to determine the accurate azimuth to an object (presumably by sighting with the camera). Elevation would also be nice, but not as critical.
Is anyone familiar with such an app? (prefereably freeware)
Thx
You can't measure Azimuth from a 2 dimensional image. At minimum you would need to input an additional parameter which you can't find out without extra equipment. (Such as the FoV angle of the camera relative to the body of the phone and the edges of the image displayed on the screen)
It's basically a compass app, and I know those exist - the camera is just for pointing (actually, I found an app to measure azimuth, but I'm still looking for elevation)

Panono: Panoramic Ball Camera

Hi there,
Some of you might have already noticed our project, a ball shaped camera you can throw into the air to capture a fully spherical panorama. We are currently running an Indiegogo crowd funding campaign to raise the funds needed. We see that many campaigns nowadays launch with apps, usually only iOS and most of them don't really put much effort into their apps. We want to go a different way as I am a long member of xda-devs and include the community into the app development. As the camera is supposed to be used with a smart phone or tablet, the app is essential for the Panono.
So what does our app actually do? Well, you can re-experience the situation captured with the Panono camera by navigating the 360x360 panoramas by moving your phone/tablet like a window into the captured moment. If my English failed to make it understandable, please have a look at the video starting from 1:22.
We are facing a problem with our app which is caused by the different implementation of the gyroscope sensor reading in different phone models. Unlike on iOS, only few Android phones have a correct algorithm to calculate the current device orientation. The result is a shaky experience in our app. We are trying our best in optimizing our app to work with all devices. To address this issue, we are also having a talk at droidcon in Stockholm right now.
So what help are we seeking right now?
We need people who have a android phone with built-in gyro test the app. The following feedback would be interesting:
Device model: (e.g. Samsung S4)
Shakyness: (e.g. image is jumping around but the orientation is correct)
Lag: (e.g. it takes a while until the correct orientation is displayed)
Jumps: (e.g. the orientation jumps into some random direction for a few frames and returns to the right direction afterwards)
You can get the app here: https://play.google.com/store/apps/details?id=com.panono.panonoviewer
If you have any question about the Panono as the next-gen accessory for your android device, you can also post here, of course.
Thanks!
