This is a simple DNS adblocker using the Pi-Hole Linux based web server. This setup was designed to be a user-friendly, "plug and play", system that you can plug in and forget about while it does all the heavy lifting. 

The hardware in this system is very straightforward:

• Raspberry Pi Zero W
• A short micro USB cable
• iPhone USB wall adapter
• 32gb micro SD card

I am very happy with this setup as it is very portable and minimally invasive. As the pictures show below, you can plug this into a wall socket and almost not notice it. I also set up with Raspberry Pi with SSH capability, therefore, I can make changes to it, if needed, anywhere on the network using Putty on windows or SSH in Linux/Mac.
