Episode 191. In this episode, we take a look at MoodleBox on the Raspberry Pi 4. MoodleBox is a custom Pi image that combines Raspbian Lite and the Moodle Learning Management System. It creates its own wireless network and operates (in its default state) completely isolated from the internet and the wired network interface.
