And the winner is...

Dude Where's my Car?

After a hard night of hacking a big congratulations to the 'Dude Where's My Car' prototype.

Ali Bros & Dylan Jones developed a journey tracking 'blackbox' that can be fitted in a car, which uses the Vodafone K3770 USB 3G modem to upload live tracking data to a host, which connects with Facebook.

The hardware features a GPS module and OBD (On-board diagnostics) interface for collecting critical parameters from an engine management system, and capable of uploading data over 3G during a typical road trip.

The host site allows a user to connect to facebook and provide updates to your profile, and share info about your trip with your friend http://dudewheresmycar.me/

So after a lot of hard work, dedication and sleep deprivation to have a functional prototype is amazing stuff. Ali and Dylan won both the The Vodafone Embedded Hardware Hack Challenge and the Facebook Open Graph Challenge http://overtheair.org/blog/programme/hackday/

Well done guys!
