I'm looking for a device that has the following capabilities:
- min 50 Hz 3-axis accelerometer and 3-axis gyroscope
- at least 1 Gb storage
- decent (rechargeable) battery (should be able to stream at least 20 hours of data)
- the smaller the better
I would be a plus, if it had any extra measuring capabilities (e.g. gps, temperature, magnetometer etc) had a sturdy casing and maybe a GSM module, but the main things are the ones I listed.
I've been looking around but haven't found one that could do all of these yet.
