A set of experimental tools

Browse and freely download the designs, or purchase a kit to get involved today.


A network of local groups

Find a nearby chapter or start one yourself to find local collaborators and support.

An open data archive

A permanent home for environmental data from grassroots groups and individuals.


Free and open source software

From map making and publishing to spectral analysis, with more new tools in development.


A platform to build collaborations
