Measuring currents with a coil

I’d like to share the work by Christoph Holz and Alexander Pusch from the University of Münster, who have created a 3D-printed coil that can be attached to the phone. This way, you can measure the current through the coil by measuring the resulting magnetic field. The have also created a phyphox experiment configuration, with which the coil can be calibrated, so you get a current-reading directly in phyphox.

This has been published in German in Naturwissenschaft im Unterricht Physik, 169, S.46-47 and a short version (also in German) can be read on physikkommunizieren.de. The phyphox configuration is listed and explained in English in our wiki.

Version 1.0.16: Japanese translation

Thanks to Wakana Okita and Keisuke Takashima phyphox now speaks Japanese. More information about our voluntary translators can be found on our languages page.

Changelog

Changes on Android and iOS

  • Japanese translation.

Changes on Android

  • Fix: The experiment “light” was not available if the list of preferred languages in Android did not support any language supported by phyphox.

Version 1.0.14: Portuguese translation

While we are still working to finalize version 1.1.0, we just published 1.0.14 with another translation: Portuguese. Check out languages page for more information.

Actually, this update has been released on Android more than a week ago and should just be a quick language update on iOS as well. Unfortunately, Apple has rejected the update as they decided that the experiment "roll" might damage the phone. So we had to remove this experiment and resubmit the app. Therefore, the update got delayed.

Changelog

Changes on Android and iOS

  • Portuguese translation.

Changes on iOS

  • Fix flickering of audio scope.

Update 17.11.2018

There was a little error when compiling the new translations that introduced unfinished translations to the iOS version, which should not yet have been released (Turkish and Chinese to be specific). We have uploaded another version (1.0.15) for iOS, which should fix this as soon as it has passed the Apple review process.

500,000 installs!

A little more than two years after our first public release (12th September 2016), we have surpassed half a million installs*. Thanks to all of you, who supported us, gave feedback or just told others about our work.

BTW: Our PhD student Dominik, got the cake from his girlfriend and though we would love to share it with all of you, a picture has to do (technical limitations, you know).

*Combined installs on Google Play (user installs) and Apple’s App Store (app units).

Public beta for version 1.1.0 available

The public beta for version 1.1.0 is available now. If you want to try the new features and give us feedback to fix any problems, please visit our forums for information on how to join the beta program.

(The beta is only available on Android as public betas are not supported on iOS. A closed beta will be offered when the iOS version is ready.)

Website downtime

After a cooling outage in our IT center, our website was unavailable from Sunday noon until Tuesday morning (CET). As you can see, it is working again. There might be a few more short hiccups as many servers at our uni were affected and the IT center is still fixing some systems, but in principle we should be back. Sorry for the inconvenience.
