Monitoring My Caffeine Intake with Computer Vision

About a month ago, I quit drinking coffee cold-turkey. Up until that point, I regularly consumed coffee, and I had been experimenting with having more coffee in my day because I both enjoyed the taste and the ritual of making coffee. This gradual increase, although initially tasty, was not a wise idea: my body didn't enjoy the amount of caffeine I had consumed. Recently, I thought: what if I had a system to remind me when I was about to hit the point at which coffee goes from being a productivity-booster to inducing negative side-effects? I also wondered whether that same system could apply to tea, which I had started drinking more regularly? I didn't need to wonder, however: I could build a system to solve this problem. In this article, I'm going to talk through my experience building a tool that lets me track how many cups of caffeinated beverages I have in a day.
