I went with a pi running pi-hole. I got it as a project where the tool is the project. But, it’s essential infrastructure now and I don’t want to mess with it incase I break it. I’m an idiot with a poor history with pi guides so far, so I will break it. It’s running the adblock fine, I assume it’s doing the tracking and malware blocking fine too.
Sadly, that’s where I leave the project for now, I had intended to give it a HDD and some… other… software but I really don’t want to break it. I tried convincing the better half that I obviously need to N+1 but she wisely did not see reason.
