Notes on plots and dataframes Before we begin, a couple of notes on plots dataframes: this post has been prepared by converting a jupyter notebook into a markdown file using nbconvert. As it turns out, the default output format used by nbconvert to display dataframes isn’t rendered correctly by the Hugo backend I’m using for the blog. I was not able to find a “clean” solution for it, so for this post (and until I’ll find the actual fix) all tables are represented in raw html, rather than in a more decent format. I also need to figure out a better way of saving the plots, which allow to specify a facecolor, so that figures have a white background both in light and dark mode. For the time being, it’s possible to switch to light mode to fix that particular problem. ...

To begin with, let’s consider the material I am working with, to have an idea of what can be done with it and what might be needed to build something clever. First off, my board is a Raspberry Pi 2 Model B (2015), which features neither a Wifi nor a Bluetooth connection. This did cause me quite a few headaches, since connecting wireless turned out to be more complex than I thought. ...
