In today’s digital world, online advertisements have become ubiquitous, popping up on almost every webpage we visit. These ads not only disrupt our browsing experience but also consume valuable bandwidth and compromise our privacy. Thankfully, Raspberry Pi Zero W, a tiny and affordable single-board computer, can come to the rescue. In this blog post, we will explore how to harness the power of Raspberry Pi Zero W to build an efficient ad blocker, enabling us to browse the web smoothly and hassle-free.

Setting Up Raspberry Pi Zero W

To begin our ad-blocking journey, we need to set up the Raspberry Pi Zero W. First, gather the necessary components: Raspberry Pi Zero W board, a microSD card, a power supply, and a computer with an SD card reader. Then, follow these steps:

  1. Download the latest Raspbian Lite image from the official Raspberry Pi website.
  2. Use an SD card formatter tool to format the microSD card.
  3. Use a disk imaging utility to write the Raspbian Lite image onto the microSD card.
  4. Insert the microSD card into the Raspberry Pi Zero W.
  5. Connect the Raspberry Pi Zero W to a power supply.

Installing Pi-hole on Raspberry Pi Zero W

Pi-hole is a popular network-wide ad blocker that can run on Raspberry Pi devices. By configuring our Raspberry Pi Zero W as a Pi-hole server, we can block ads across all devices connected to our local network. Follow these steps to install Pi-hole:

  1. Connect to the Raspberry Pi Zero W via SSH using the default credentials.
  2. Run the Pi-hole installation command provided on the official Pi-hole website.
  3. Follow the on-screen instructions to customize the Pi-hole installation settings.
  4. Once the installation is complete, access the Pi-hole admin interface through a web browser.
