Video about why and how I made this, and what the various iterations were like: https://www.youtube.com/watch?v=h-Cdl4Vq9H4

This repository contains the code, schematic, PCB layout, and 3d model for a completely DIY gaming mouse, all designed around a Pixart PMW3360 sensor.

The firmware for this mouse uses a special debouncing algorithm that completely eliminates chatter without adding ANY latency, and eliminates bounce better than commercial mice do. Random double-clicks be gone!
