I had read about the pi-hole project, and decided to make one, because the Raspberry Pi is neat hardware and I hate ads and tracking. Having once work in ad-tech I can attest to how soulless and disturbing it is.
I bought a Raspberry Pi 3 Model B+, a heat sink, a nice little case and a power supply and a 16GB class 6 micro SD card. I had to do some reading on the SD card classes, not knowing exactly what they meant. It seems for general computing purposes the class 6 devices have the best balance of read and write speeds.
Installing raspbian was nice and easy. I was quite pleasantly surprised. The pi-hole install was also very easy and I had the whole thing set up and running in short order.
So, what do I think? I think it's damn nifty. There are strange issues here and there with various devices in the house that need to 'phone home' but that are caught in one of the various black lists, so I need to keep an eye on what is being goofy, but so far everything 'just works'. The web UI is really nice, with a concise dashboard that gives a nice overview of the system.
I am looking forward to messing with little thing more.
Update: So the issues I was seeing were resolved by bouncing the network connections on the devices that were acting strangely. So far everything is back to normal, just with out ads and tracking URLs.
