I recently got a Raspberry Pi 4 and started messing around with it. It’s pretty impressive what you can run on such a small machine, but the main reason I got it was to install Pi-hole. Pi-hole is a DNS-based adblock that will work for any device on your network. I already have adblock on my computers, but it seemed like a nice way to block things on my phone and possibly my smart TV. It’s up and running now and it’s helpful for the phone. Unfortunately, it does not black YouTube ads since those are not a 3rd party but hosted by YouTube itsefl. I’ll probably do some more experimenting with the Pi but this is good for now.
