Just a quick update on two new opportunities in NRW to see us and discuss ideas:
In this new update two new experiments have been added: Centrifugal acceleration and inclination. While the latter is just a tool to measure the inclination of a plane, centrifugal acceleration is a lot of fun while being amazingly simple. Just rotate your phone at a fixed radius r at different angular velocities ω to visualize the relation of the centrifugal acceleration a.
In other words: Just put your phone into a salad spinner or on a carrousel to show a = r·ω². (The picture shows an earlier version of the experiment using a salad spinner)
Besides that, 1.0.3 introduces some new analysis modules (the wiki will be updated in the next few hours) and addresses many bugs, especially two common crashes on iOS. Here is the full changelog:
- New experiments: Centrifugal force and inclination
- Simple view for raw sensors, just giving numbers
- Improved descriptions and labels for several experiments
- Better time axis calculation in elevator experiment
- Updated experiment file format to 1.2: New modules for statistics and trigonometry. Also more control over value and graph view elements.
Fixes on iOS
- Disappearing view elements after rotation or scrolling
- Crash when starting web interface on iOS8
- Crash when entering zeros in Doppler effect
- Crash in autocorrelation module (experiments “Spring”, “Pendulum” and “Autocorrelation”)
- Missing data points in remote interface (mostly elevator and roll)
- Could not open external experiments on iOS8
- Strip white-spaces from description
Fixes on Android
- Fix wrong play-button animation after screen being turned off
- Do not show the save-locally-dialog again after rotation
- Show “-” instead of “NaN” when no data is available
- Improved reliability of remote interface when doing partial data updates
- Fix possible crash when switching apps while graph is visible
- Fix crash when closing experiment without dismissing the info-tooltip
The sonar might be one of the most fascinating experiments, but also one of the most confusing ones if you do not know how to do it properly. This video explains, how to turn your phone into a sonar.
We have just released version 1.0.2 which mostly adds some guides to alleviate some typical confusion for new users:
- Hint to guide inexperienced users to the experiment info.
- Ask if externally loaded experiment should be added to collection. (You can still do so later via the menu as before.)
- Disable back swipe gesture to avoid involuntarily closing an experiment when swiping between tabs. (iOS only)
- Limit min/max of allowed values in some experiments (phyphox file format has been updated for this)
- Values entered in experiments are now only used for calculations after the user confirms the input (hitting the confirmation button on the virtual keyboard) or changes the focus away from the edit box. This behaviour now matches the one from the iOS version and prevents unnecessary recalculations while entering numbers. (Android only)
- Fix decimal values not being allowed. (iOS only)
- Fix problematic recalculation when clearing buffer. (iOS only)
- Handle flawed phyphox files more gracefully and report errors. This will be improved further in future updates. (iOS only)
We have just releases version 1.0.1 with bug fixes for iOS (on Android version 1.0.0 remains the most recent version):
- Fix crashes on iPad when trying to export data or sharing a screenshot.
- Fix rare crash in experiment most likely to occur when switching apps or displaying a dialog.
- Fix remote interface being unable to reconnect after switching to a different experiment.
If you find more errors, please tell us and bear with us. Especially, if the experiment editor or its results are not working as expected, just write an email to firstname.lastname@example.org and I am happy to help your.
This is it, the great kick-off. Today (Monday, 12th September 2016) phyphox has been released to the public. Go ahead and get it from Google’s Play Store or Apple’s App Store (for free, of course).
If you are not yet sure, what to do with it, have a look at our videos and the experiments in the Wiki. There are not yet that many videos, but from now on I will add more experiment videos about once a month. If you want to know about any new content or updates right away, you should follow us on your preferred social media platform:
Of course, there is still a lot to do and this is just the start. Please let us know what you do with phyphox, tell us about any great ideas for new experiments and of course report bugs and missing features.
Cheers to you all and have fun with phyphox!
The magnetic ruler is more a tool than an experiment on its own. It allows you to determine distances and speeds by marking distances with simple magnets.
In this experiment, you can track the velocity of a roll using the gyroscope of your smartphone.
