Data Logging and Processing As the Arduino GPS data logger saves the periodic samples containing data on recorded positions to a microSD memory card, this data can then be imported into a computer ...

Now you can prove that you have the bumpiest commute in the office by measuring how rough your ride actually is. [Techbitar] calls the project the Bump-O-Meter. It uses an Arduino, GPS, and acceler… ...

The Mayfly Data logger is a fully programmable microprocessor board which is fully compatible with the Arduino IDE and is equipped with a Atmega 1284p processor supported by 128K flash memory and ...

There really is not much to building the GPS Data Logger other than stacking the shields in the correct order, uploading the code to the Arduino, and then getting outside and logging some data.

It is an Arduino compatible board (hardware, not footprint) based on the ATMEGA1284P which can be programmed to collect and post data to internet logging sites such as Thingspeak or Xively.

But it's possible to go even smaller, as the makers of a new Arduino-compatible product called "Microduino" show. At 1" × 1.1", it's nearly as small as a quarter.
