After seeing AirGradient's DIY Air Quality monitor based on the ESP8266 and some common sensors, I decided to integrate multiple monitors in my home. I made this video, which shows how I did everything, and I built and maintain an AirGradient Prometheus exporter on GitHub (https://github.com/geerlingguy/airgradient-prometheus), which lets me store the data from the air quality monitors in my local Prometheus instance.

Raspberry Pi configuration for all things Internet! This open source Ansible playbook configures a Raspberry Pi with Pi-hole, Prometheus, and Grafana, to help control and monitor your Internet connection. It also includes other optional monitoring dashboards for monitoring more things in your home!

This collection includes helpful Ansible roles and content to help with macOS automation tasks. For a good example of the collection's usage, see my open source Mac Devevelopment Playbook, which I use to set up and synchronize the configuration on all my Macs!

I built this Raspberry Pi PCI Express device database using GitHub Pages, and I am maintaining a repository where I'm testing, documenting, and discussing a variety of PCI Express cards that I am testing with the new Raspberry Pi Compute Module 4 and its companion IO Board. Videos from the project are posted infrequently on my YouTube channel: https://www.youtube.com/c/JeffGeerling

I delivered a series of live streams teaching Kubernetes to developers around the world. The streams are on YouTube, the website is hosted on GitHub Pages (and built with GitHub Actions and Jekyll), and the code examples are on GitHub in the repository https://github.com/geerlingguy/kubernetes-101

I spoke on a panel at DrupalCon Global 2020 about local development environments for developing Drupal websites.

I released the sixth major version of Drupal VM, a popular development tool for Drupal websites.

I shared the results of extensive testing I performed with various SSDs and external storage options for the Raspberry Pi.

I built a 7-node K3s cluster using a Turing Pi and Raspberry Pi Compute Modules, then open-sourced all the cluster configuration and made a free video series on YouTube.

I live-streamed an educational series on YouTube about Ansible based on my book, Ansible for DevOps.
