HOUGHTON — For five Michigan Technological University students this year, their homework includes their actual home.

This is the first year for Tech’s Sustainability Demonstration Home, where the students are tracking their energy and waste, as well as carrying out projects on how to reduce energy use.

“This semester, we’re kind of working side by side,” said Rose Turner, a fourth-year environmental engineering student and the only of the house’s residents on the Enterprise team.

Cooper Mineheart, a second-year mechanical engineering student, has learned what he can and can’t recycle.

Thomas Richter, a fourth-year mechanical engineering student, said his consciousness of how small changes add up will stick with him after he leaves the house.

Abstract

Distributed digital manufacturing of free and open-source scientific hardware (FOSH) used for scientific experiments has been shown to in general reduce the costs of scientific hardware by 90–99%. In part due to these cost savings, the manufacturing of scientific equipment is beginning to move away from a central paradigm of purchasing proprietary equipment to one in which scientists themselves download open-source designs, fabricate components with digital manufacturing technology, and then assemble the equipment themselves. This trend introduces a need for new formal design procedures that designers can follow when targeting this scientific audience. This study provides five steps in the procedure, encompassing six design principles for the development of free and open-source hardware for scientific applications. A case study is provided for an open-source slide dryer that can be easily fabricated for under $20, which is more than 300 times less than some commercial alternatives.
