Developer builds Pi-hole-style ad blocker on a $2 ESP32-C3

Original: M-Abozaid/esp32-c3-adblock

A developer going by M-Abozaid has released an open-source project that turns a $2 ESP32-C3 microcontroller into a network-wide DNS ad blocker comparable to Pi-hole. It stores 537,000 blocked domains as 40-bit FNV-1a hashes in flash and searches them with binary search, running a UDP DNS sinkhole with a web dashboard — all without PSRAM. The project is drawing attention on GitHub for fitting so much into minimal hardware.

Why now: The hobbyist hardware community is impressed by a $2 chip replacing dedicated ad-blocking hardware.
