During out SYSTEMS fair presentation, an idea was born: an external sensor box!
There is an initial discussion (in German):

Features
- analog sensors
- connected as USB (host)
- battery extender (?)
Analog Sensors
- Temperature
- Humidity
- Barometer
- Magnetic compass
- Light intensity / Colorimeter
- Laser / Ultrasonic distance
- Voltmeter / Simple Oscilloscope (?)
Other proposed extensions
These ideas go beyond the original Sensorbox idea but some of them can be easily added:
- LED lamp
- GPS Antenna
- Battery pack
- Camera
- USB Hub
- RJ45
Mechanics
There is currently some discussion if it should be a Jacket or an external box. http://freeyourphone.de/portal_v1/download/file.php?id=51
Electronics
- a low cost, low power single chip processor with USB and ca. 8 x ADC (which one? Please go to discussion page)
- power comes through USB
- USB A/f so that the standard client cable can be connected
Software
- Device is addressed as a simple serial interface over USB
- allows to switch on/off each sensor (so that power drainage can be controlled)
- sends every 0.1 seconds a data block with latest data values
- User-Interface runs on the Freerunner
