Tartanhacks 2018
As a freshmen, I participated Tartanhacks 2018, which is a CMU hackathon. With three other juniors, we built a "receipt garbage box." We built this because we thought keeping and organizing paper receipts are outdated for this century. What you can do with this is when you insert a receipt, the device takes a picture and scans your receipt, and you can keep track of these receipts on the website that we also built.
