As we're setting everything up for Codebits 2011, we already have another contest on the way: Innovation Challenge (website and rules in Portuguese).
The main focus is the development of a mobile application (Android or iOS based) targeted at energetic efficiency.
Prizes range from Androids and iPhones and go up to monetary prizes of up to 7,500€. The winners will be announced during Codebits (which also means that the finalists will get accepted for the event, of course).
The Innovation Challenged is divided in two stages:
This means that you won't need to implement anything unless the jury approves your project at the end of the first phase.
Good luck, have fun!
