To vam omogu\u0107uje prijenos Arduino koda na ESP32 kontroler s PSRAM memorijom, a zatim spajanje usmjeriva\u010da na njega. To vam daje hardverski blokator oglasa koji ko\u0161ta manje od va\u0161e jutarnje \u0161alice kave.<br><br>U svojoj sr\u017ei, ESP32_AdBlocker radi to\u010dno kao Pi-hole. Kada bilo koji ure\u0111aj na va\u0161oj mre\u017ei poku\u0161a pristupiti odre\u0111enoj domeni, poput poslu\u017eitelja oglasa ili alata za pra\u0107enje u aplikaciji, prvo tra\u017ei od DNS poslu\u017eitelja da prevede domenu u IP adresu. Uobi\u010dajeni usmjeriva\u010di proslje\u0111uju ovaj zahtjev davatelju internetskih usluga ili vanjskom DNS-u. Me\u0111utim, s instaliranim ESP32, sve domene na popisu blokiranih vra\u0107aju se s adresom 0.0.0.0. Veza se odmah prekida, ure\u0111aj ne u\u010ditava oglas i ne tro\u0161i mre\u017enu propusnost, bez obzira o kojem se ure\u0111aju radi.<br><br>Projekt koristi ugra\u0111enu PSRAM memoriju za pohranjivanje popisa blokiranih domena. Pretrage domena su izuzetno brze i obi\u010dno traju manje od 50 do 100 mikrosekundi na standardnom ESP32 \u010dipu, \u0161to je br\u017ee od komunikacije s vanjskim DNS poslu\u017eiteljima. Svi zahtjevi koji nisu blokirani proslje\u0111uju se na va\u0161 odabrani vanjski DNS poslu\u017eitelj bez ikakvih problema.<br><br>Glavni hardverski zahtjev je prisutnost PSRAM memorije. ESP32 plo\u010de dostupne su u verzijama s 4 MB ili 8 MB PSRAM-a. Preporu\u010duje se kori\u0161tenje verzije od 8 MB, kao \u0161to je model ESP32-S3, koji ko\u0161ta izme\u0111u 5 i 10 eura. To vam omogu\u0107uje pohranjivanje cijelog konsolidiranog popisa blokiranih domena (kao \u0161to je Steven Black) izravno u memoriju. U verziji od 4 MB, popis se automatski skra\u0107uje, ali i dalje nudi dobru za\u0161titu. S ovim projektom nema potrebe za kupnjom microSD kartica, odr\u017eavanjem operativnog sustava ili instaliranjem sigurnosnih zakrpa. Ukupni tro\u0161ak, uklju\u010duju\u0107i USB kabel i punja\u010d, ne prelazi 15 eura.<br><br>Instalacija se vr\u0161i putem besplatnog Arduino IDE-a. Nakon preuzimanja datoteka s GitHuba, odabirete odgovaraju\u0107u shemu particija koja dodjeljuje PSRAM memoriju i pi\u0161ete program na plo\u010du. Prilikom prvog pokretanja, ESP32 djeluje kao Wi-Fi pristupna to\u010dka. Pove\u017eete se s mre\u017eom, odete na 192.168.4.1 i unesete podatke o svojoj ku\u0107noj Wi-Fi mre\u017ei i URL popisa blokiranih domena (u HOSTS ili AdBlock formatu). Posljednji korak je postavljanje stati\u010dke IP adrese za va\u0161u plo\u010du i unos ove IP adrese kao zadanog DNS poslu\u017eitelja u postavkama va\u0161eg usmjeriva\u010da.<br><br>Web su\u010delje omogu\u0107uje vam pra\u0107enje preuzimanja i analizu blokiranih domena u stvarnom vremenu. Budu\u0107a a\u017euriranja prenose samo razlike u podacima, \u0161to ubrzava performanse. Iako sustav ne nudi napredne grafikone ili funkciju DHCP poslu\u017eitelja poput Pi-holea, izvrsno je, ekonomi\u010dno i jednostavno rje\u0161enje protiv trackera.<\/p>\n<div class=\"embed-container\"><iframe src=\"https:\/\/www.youtube.com\/embed\/E6E_KrfyWFQ\" frameborder=\"0\" allowfullscreen><\/iframe><\/div><br\/>","protected":false},"excerpt":{"rendered":"<p>Da biste svoj ESP32 pretvorili u mre\u017eni ubojicu DNS zahtjeva, trebat \u0107e vam projekt otvorenog koda na GitHubu pod nazivom ESP32_AdBlocker.
