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

Original: M-Abozaid/esp32-c3-adblock

A developer known as M-Abozaid has released an open-source project that turns a $2 ESP32-C3 microcontroller, which lacks PSRAM, into a Pi-hole-class DNS ad blocker. The software stores 537,000 blocked domains as compact 40-bit FNV-1a hashes in flash memory and searches them with binary search, running a UDP DNS sinkhole alongside a web dashboard. Enthusiasts are discussing the efficient use of minimal hardware for whole-network ad blocking.

Why now: The project's ability to replicate dedicated ad-blocking hardware on an extremely cheap microcontroller is impressing the maker community.
