The Gathering for Open Science Hardware (GOSH) is a community of professional and citizen scientists, educators, and other open science enthusiasts that are working to advance discovery through leveraging the scientific opportunities created by open hardware.  Funds from this grant provide two years of support for GOSH’s core community-building and development activities.  Funded activities include planning and hosting of the GOSH annual meeting, development of a model for regional and topic-focused GOSH events, outreach to university administrators and other potential funders, and a “collaborative development program” that would seek to support open hardware projects through an experimental combination of online project development with time-bounded in-person intensive collaboration.
