Salty Sensor Contest

Contributors: Hendrik Hagala (Primary Research), Last Updated: March 17, 2021

 

Oceans cover 75% of the blue marble we call home. Monitoring environmental conditions in the ocean's ecosystems is a vital but difficult task. Until now, deploying sensors was an expensive proposition, limiting research to projects run by universities and a handful of well funded NGO's.  We challenge hackers and makers to use your skills and creativity to help design new, cheaper, open-source hardware and software floating or diving sensor buoys to democratize marine environmental research.  We will kick-off with tech talks by experienced sensor builders and oceanographers. Teams with winning designs will have the opportunity to visit the OceanBuilders Blue Frontier incubator off the coast of Panama and see their design deployed to monitor the coastal ecosystem.

This contest presents a technically demanding challenge for creating new open-source hardware and software design concepts and draws on a broad variety of skills from across the hacker community, and supports a worthy cause. A new career and lifestyle on the "blue frontier", where a hacker approach to solving problems is a must, may be the life adventure some DEF CON attendees didn't know they were looking for.

The hackathon will kick-off the first day of DEF CON, and there will be opportunities and space at Hack The Sea Village during normal conference hours for teaming, collaboration, and discussion with experienced seasteaders and sensor designers from projects like UCSD's Argo and DARPA's Ocean of Things each day.

PROBLEM

The world's coral reefs are dying. The ocean's ecosystems are in decline. We need to understand the problem and have it backed up with real data so that we can find solutions.

 

SOLUTION

We would like to build an inexpensive, multi-purpose, remote monitoring buoy which can be reproduced globally so we can get real data to understand the problem and work towards real solutions. The buoy should consist of multiple sensors which can continuously collect scientific research data. The ideal solution, for bonus points, would be able to transmit the data to a central station for analysis. Here is a similar project built by some students (https://www.instructables.com/id/Smart-Buoy/). A typical line of sight radio transmission is 3 miles (https://en.m.wikipedia.org/wiki/Line-of-sight_propagation) unless there is a raised antenna.

 

PRIZES

The winning team will get:

• An all expense paid trip to the Ocean Builders Launch site in Panama where they can see your creation put into use. This includes airfare, travel, food, and miscellaneous expenses up to $1,500 for up to 3 people.
• A cash prize of $500.
• Each team member will get one nights accommodation in a SeaPod Floating Home ($500 value per person).
