A while ago I made a smart mirror for my bathroom. Maybe you’ve seen it. It started with a particular image in my mind. I wanted to build a piece of technology for the home that feels new and futuristic, yet simple and clean. The mirror blends in seamlessly with its environment and doesn’t aggressively compete for my attention. I wrote about how it works and the parts I used, source code included.

It’s been two years, and I’ve been using this prototype every day. I’ve since added a couple of features to the software that the initial version didn’t have. For example, I connected it to my smart scale to show my weight trend, and it tells me the traffic to work each morning.
