An interactive demo of QR codes' error correction operates in show hn launch.

Profile

Hi HN! This is a hobby project of mine that recently landed me my first interview and helped me get my first internship offers.Draw on a QR code, and the health bars will accurately display how close the QR code is to being unscannable. How few errors does it take to break a QR code? How many errors can a QR code handle? Counters at the bottom track your record minimum and maximum damage. (Can you figure out how to break a QR code with 0.0% damage to the actual data region?)Also, click on the magnifying glass button to toggle between "draw mode" and "inspect mode". I encourage you to use your phone's camera to scan the code as you draw and undo/redo to verify that the code really does break

Its activity falls under show hn launch; the profile below is assembled from public directory data.
