Digital Engineering Consultant
The J. Simmons, LLC

I am an OSHW advocate and the founder of Mach 30, a US non-profit dedicated to developing OSHW for spaceflight. I was the lead developer for the Shepard Test Stand (OSHW Certificate US000006, http://opendesignengine.net/projects/shepard-ts), an open source Estes rocket motor test stand to support educational and outreach activities. I have also presented at the 2012, 2013, and 2015 OSHW Summits where I covered topics ranging from open source spaceflight hardware to export controls to open source engineering analysis.

In 2012, I was the chief architect and project manager for Open Design Engine, an all inclusive web application for hosting OSHW projects. Since the launch of Open Design Engine, I have focused my effort on collecting lessons on what it takes to effectively develop, collaborate, share, and remix OSHW projects in academic, commercial, and volunteer settings.
