iPods as scientific tools (app-creation challenge)
I have a half-warmed idea that this is an under-exploited resource - these things are packed with sensors that most schools cannot afford to buy for themselves.
Does anybody know of any apps that can be used to easily access this data in a form useful for students?
For instance: the iPod replaces the bob in a pendulum and records the time it takes to swing, and the forces acting at each moment of the swing, then displays the data in a graph on the iPod, or uses the wifi link to email the document in a form that can be used by an Excel spreadsheet.
And not just acceleration and time, but sound and light (isn't there an ambient brightness detector in there somewhere?).
Kitewife bought me an iPod Touch for Christmas! I have so far installed the following apps that use the on-board sensors;
- SPARKvue (accelerometer display),
- Signal Gen (an audible signal generator),
- SoundLevel (a free decibel meter / sound oscilloscope)
- FreqCounter (displays a continuous full-screen oscilloscope display
- Decibel 10 (analogue & digital sound level meter, which will email data for you)
- SpiritLevel & iTools (for measuring angles and levels by moving the iPod)
- Protractor (lays a protractor over the view through the camera, allowing you to measure "real" angles you can't reach (say, of a roof-line, or between branches of a tree).
The next job is to find ways to use them in lessons, or as homework tasks.
Question: Is anybody reading this able to actually create their own iPod Touch apps? The apps I've downloaded so far are fine, as far as they go, but they really need a better way of getting the data out in a form that can be manipulated (eg by spreadsheets).
