When I originally built the Raspberry Pi Dramble 6-node Pi cluster in 2014 (for testing Ansible with bare metal hardware on the cheap), I compiled all the code, notes, etc. into a GitHub repository . In 2015, I decided to take it a step further, and I started hosting www.pidramble.com on the cluster , in my basement office !

Every time I've shared the cluster with others during presentations or at events like DrupalCon, someone asks how it's built. While I do have almost all my notes and instructions for building the entire cluster on the Pi Dramble Wiki , a step-by-step visual guide is better. Therefore, I'm posting a series of videos, "Let's Build a Raspberry Pi Cluster", to my YouTube channel .

The first video goes over hardware parts and setup:

The second goes over microSD card setup and Raspbian OS configuration:

These videos also serve as background material for those attending my upcoming talks on Drupal 8 and the Raspberry Pi:

• Raspberry Pi with a Side of Drupal 8 Acquia Booth, Wednesday afternoon, 3:15 p.m.
• Highly-available Drupal on a Raspberry Pi Cluster php[tek], May 25, 3:30 p.m.

I'll post again once I've wrapped up the video series (it will likely be either 5 or 6 parts total). What do you think of the videos? Should I consider making more of this kind of video, or ditch the idea and stick to writing?
