Public Invention

“Equipment: $17,912.50 -- Equipment is our largest expense. We purchase equipment for volunteer, unpaid engineers to prevent them having out of pocket expenses.”

“Research -- $61.58 -- pay wall research papers”

“Travel $6,501 -- All of our travel is to confereces of conventions. This year we presented at Maker Faire Bay Area and the IEEE IMBH conference in Pittsburgh, the American Society of Engineering Education, and the Open Source Hardware Alliance.”

“Job Supplies -- $659 -- expendable supplies, such as jumper wire, solder, etc.”

“Books -- $584 -- technical books required to be cited in our peer-reviewed publications.”

“Bank Chargers and Fees -- $73.86”

“PolyVent (deleted): -$2,706.39 : This year we shifted to "Fund accounting": but had left over expense categories.”

“NASA-COG (deleted) : -$28.53 : This year we shifted to "Fund accounting", but had left over expense categories.”

“Advertising and Marketing $3,952 -- This includes our website, MailChimp, and other expenses.”

“Tools -- $324 -- Reusable tools, such as wire crimpers”

“Public Invention does not pay its board members, or its President and Founder, who acts as an executive director, in any way. This year we did a major contract for NASA to develop a digital control system for a Ceramic Oxygen Generator (COG). This technology can fill spacesuits and generate an oxidizer from the Martian atmosphere but more importantly, it can revolutionize the delivery of therapeutic oxygen, which is a miracle drug for those diseases that require it, in rural low- and middle-income countries. The PolyVent Ventilator is the worlds most open source education and research ventilator. The project was winding down, but has recently been delivered to Colorado Mesa University for both research and classroom instruction in 2024. Public Invention runs a number of small projects, each aimed at academic publication, which do not require large amounts of money, and so are not listed on this form. For example, we have developed a passive ferrofluid check valve that is a true invention. Public Invention is a driving part of a coalition of nonprofits in the Global Opens Source Quality Assurance Systems (GOSQAS) alliance. We are innovating the last-mile tracking of medical goods outside of normal inventory control systems with a camera based system that requires no authentication and no login at all. We hope this will lead to a revolution in the quality of medical supplies globally, an increase in medical philanthropy, and will fight counterfeiting. The expenditures listed on this form fell into no other categories and total $35,287”
