TL;DR

A low-cost ad-blocker was developed using the ESP32-C3 microcontroller, capable of blocking ads for 537,000 domains through a DNS sinkhole and a web dashboard interface.

✦ Why It Matters

Consider building your own ad-blocker with the ESP32-C3 to enhance your network's privacy today.

Key Takeaways

Utilize the esp32-c3-adblock for cost-effective ad-blocking.
Store domain hashes in flash to save RAM resources.
Leverage the web dashboard for easy management.
Ensure security by setting strong passwords in the configuration.

How It Works

The esp32-c3-adblock uses a unique method of storing domain names as 40-bit hashes in flash memory instead of loading them into RAM. This allows for efficient binary searching of the hashes, which significantly reduces memory usage and lookup times.

The design accommodates a large number of domains while maintaining low collision rates, making it an effective solution for DNS ad-blocking.
