Developer Builds Pi-hole-Style Ad Blocker on $2 ESP32 Chip

Original: M-Abozaid/esp32-c3-adblock

A developer has released an open-source DNS ad-blocking tool that runs on a $2 ESP32-C3 microcontroller with no PSRAM. The project stores 537,000 blocked domains as 40-bit FNV-1a hashes in flash memory, searched via binary search, and operates as a UDP DNS sinkhole with a web dashboard. It replicates core Pi-hole functionality on minimal, low-cost hardware.

Why now: The project is trending on GitHub because it packs Pi-hole-class ad blocking into extremely cheap, minimal hardware.
