ProtoPCB Code and Evaluation Files

This repository contains our tests, evaluation files, and software tool (ProtoPCB) presented in the paper "ProtoPCB: Reclaiming Printed Circuit Board E-waste as Prototyping Material", which will appear at CHI2025. This tool was built by Jasmine Lu (@xjasminelu), Sai Rishitha Boddu (@rishiboddu) with project assistance from Pedro Lopes at the University of Chicago's Human Computer Integration Lab.
