The Missing Clusterhat Tutorial
As a project, I decided I wanted to learn more about Cluster computing. The cheapest way to do this, of course, is with a cluster of Raspberry Pis. There are several truly impressive Raspberry Pi clusters across the internet, but the cheapest and easiest option I could find was the ClusterHat. The ClusterHat is a shield for a Raspberry Pi 3 or 4 which allows you to attach four Raspberry Pi Zeros as nodes to a Raspberry Pi 3/4 easily.
