LightboxDIY™ is a community of socially responsible makers focused on creating innovative solutions to tackle the shortage of masks. Our project was spun out of a non-profit that focuses on technology education and innovation. Our aim is to take readily available, off-the-shelf parts to build a set of design specifications for an affordable system that could meet the requirements and standards set forth by leading scientific and regulatory bodies for sanitizing reusable PPE.
