In the past few years, we have covered plenty of fun Raspberry Pi projects here. This Pi-Hole Ad Detection kit for Raspberry Pi is also worth a look. It lets you avoid connecting to adservers and achieve faster connection. The kit also comes with a 2.8″ PiTFT display.
You can use this kit with the Raspberry Pi 3 Model B. A Pi 2 can be used with a WiFi dongle too.
