What Happened in May 2022

Hardware hacking:

• More playing with ESP32. Try making an open-window detector with the built-in Hall effect sensor, and sending a Grafana annotation when it’s open.

Programming:

• Refactor my .emacs files to use a lisp directory, and switch to use-package rather than Cask. This is easily the longest-running project I’ve been working on:

commit 85b1d148afdc135d725498c0384d58e7baa0866d
Author: Hugh Brown <hugh@chibi-laptop-01.(none)>
Date:   Tue Mar 3 21:13:57 2009 -0800

    New repo.

…and that commit came after declaring bankruptcy in the last one.

Data science:

• Analyze EV data from road trip to Penticton. Here’s a nice map showing our altitude as we drove. It’s not much of a data science, but it’s something.
