Add your Raspberry Pi to Rastrack
Rastrack is a project started by Ryan Walmsley from the UK. The goal of this project is to track the geographic location of the Raspberry Pi owners. Raspberry Pi owners can add their location and it will be shown on Google Map available at http://rastrack.co.uk/:
To add your device to the map, select the Add to Rastrack option in raspi-config:
This will open up a wizard that will guide you through the process. Note that the internet connection is required.
