This is an EXCELLENT idea! Which transfers the risk to the donors phone!
@nlinecomputers I need to go through that tutorial more, but caution... linux needs patched too. And those little pi projects tend to turn into yet another IoT device with all the headaches that go with it.
*Edit* yep, tutorial neglected the cron job to run apt update && apt upgrade like it asks for in the beginning. Also anyone that's used Untangle's physical console can tell you how annoyingly limited Chromium is in that context. It does strange things, and just flat doesn't work for many websites.
