MadHacks Carbon encourages competitors to bring their creativity and ingenuity to engineer solutions for sustainable living.

Madhacks is the University of Wisconsin's twice-annual hackathon, bringing together participants from all over the US and Canada for 24 hours of hacking. Unlike other hackathons, MadHacks is going to be putting emphasis on the wacky, the original, and the downright impossible!

Madhacks 2019 - Carbon will take place on October 19-20, 2019 in the Education Building at UW-Madison (1000 Bascom Mall, Madison, WI 53706). We look forward to seeing you all there!

MadHacks Carbon encourages competitors to bring their creativity and ingenuity to engineer solutions for sustainable living. Whether it's carbon emission, waste management, power efficiency, environmental agriculture, or any other concern, bring your ideas here. The collaborative spirit of our event will inspire teamwork and real implementation of your exciting ideas.

Judging Criteria

  • Technicality
    Your project will be judged on its technical difficulty and complexity. How much of the code did you write and how much of them was using an API or outside library.
  • Originality
    Has this project been done before? If your project is to address a particular problem in society, does it actually solve that problem? Try to think out of the box and create a project that can wow our judges.
  • Impact
    Does your project address a specific problem that we are facing in society? If not, do you think people will actually use the project that you create? Why do you think so?
  • Design
    Did you take into considerations some user experiences to make your project more easy to use for users?
  • Learning
    Regardless if your project can actually run during the demo, what have you learned? What obstacles have you run into? Do you have a good story to tell about this learning experience?
