Phakamisa isandla sakho uma wazi ukuthi lokhu kungaholela kuphi! Kulungile, konke lokho kuyathakazelisa, kepha uma ubhekisisa kakhulu isibonelo se-65 mph, uzoqaphela inkinga encane. Idivayisi yami ihlale idlulisa leso sivinini ngoba isebenza ngefrikhwensi engaguquki, kodwa kuthiwani uma ngidlula esikoleni esinesivinini esilinganiselwe? Ngaphandle kwalokho, ngeke sazi kahle ukuthi i-radar yamaphoyisa isakaza kangaki.
Kodwa, bangane, kufanele ngisho, siphila ezikhathini ezithakazelisayo. Siphila esikhathini esizayo lapho lonke ulwazi lomhlaba lusesandleni sethu, futhi singenza ngalo noma yini esiyifunayo. Izitholi ze-radar zemoto ezintsha, ikakhulukazi i-Valentine One kanye ne-Escort 360, zithola amasiginali e-radar atholakala cishe ngamamayela angu-2-3 ngaphambi kwemoto yakho futhi, nge-Bluetooth, abonisa ulwazi ngemvamisa ye-radar yamaphoyisa ekhipha lezi zimpawu (ihlombe).
Ngizoma isikhashana ukuze ngibonge u-Tri Wolfe, lapho ehlezi khona, ngokunginikeza indawo enethezekile ukuze ngiqhube ezinye izivivinyo, ngokusemthethweni nangokusemthethweni ngokuphelele.
(23:50) Ngakho, okudingeka sikwenze nje ukudala uhlelo lokusebenza olusitshela umkhawulo wamanje wesivinini—uhlobo lwe-API yomgwaqo. Izithungatha zamarada zesimanje zinhle kakhulu ekutholeni imvamisa yamaza erada yamaphoyisa ebangeni elingafika kumamayela amabili. Ngokusekelwe kulokhu, singakwazi ukubala umkhawulo wesivinini samanje imoto yakho okufanele ihambe ngayo kanye nemvamisa yesiginali edlulisa leso sivinini.
Esikudingayo iphrosesa encane kakhulu. Isilayidi sibonisa i-ESP 8266 microcontroller; kwanele ngokuphelele. Kodwa-ke, inkinga iwukuthi ama-SDR atholakalayo njengamanje, noma imisakazo echazwe ngesofthiwe, ayisebenzi kule-high-frequency noma i-microwave spectrum; zenzelwe i-low-frequency spectrum. Kodwa uma uthatha ngokungathi sína ngehadiwe, ungakha idivayisi esiyidingayo ngemali elinganiselwa ku-$700. Iningi lalezo zindleko zizovela ekuthuthukiseni i-SDR ukuze idlulise imvamisa ephezulu.
(25:10) Nokho, i-FCC ayifuni ukuba wenze lokhu. Ukusebenzisa idivayisi ye-radar jamming yicala elinenhlawulo engu-$50,000, iminyaka emihlanu ejele, noma kokubili. Ama-jammer e-radar avinjelwe e-United States kusukela ngo-1996, okwenza noma ubani osebenzisa noma othengisa lawa madivayisi abe ubugebengu bombuso.
I-Federal Communications Commission ithatha lokhu njengento ebaluleke kakhulu kangangokuthi awukwazi ngisho nokukhangisa lawa madivayisi noma ukukhuthaza ukusetshenziswa kwawo. Uma ubhekisisa le divayisi engu-$700, uzobona ukuthi ayishibhile ngempela. Kodwa ngokuqonda indlela yokwenza i-radar jammer, siyenza ifinyeleleke, bese ungenza isinqumo esifanele—ukuthi uzoyisebenzisa noma cha.
Ngakho, i-FCC ngeke isivumele ukuthi sisheshise le nqubo. Ngakho-ke, ake sibheke ukuthi yiziphi izinyathelo ezisebenzayo nezisemthethweni ezitholakala kithi. Zikhona futhi zitholakala kalula. Uma ungakwazi ukufinyelela kuzitholi zesimanje ze-radar zikagesi, sebenzisa ezinye izisetshenziswa; ukukhetha kukhulu.
Izitholi zesimanje ze-radar ezifana ne-Uniden R3/R7, i-Escort Max360, i-Radenso Pro M, noma i-Valentine One w/BT zinhle kakhulu ekutholeni noma imaphi amaza omsakazo, womabili aboniswa futhi aqondile, ebangeni elingafika kumamayela angu-2, kodwa awakwazi nhlobo ukuthola ama-laser. Kodwa-ke, abantu abaningi bayazi ukuthi amaphoyisa asebenzisa ama-laser ukukala isivinini. Futhi nansi i-lophole! Iqiniso liwukuthi ukulawula ukusetshenziswa kwemishini ekhipha ukukhanya, okuyizinsimbi, akukona ngisho nombono we-FCC—i-FDA's. Ngakho makube khona ukukhanya!
Kuvele ukuthi lezi zibhamu ze-laser zihluke kakhulu kwezabo amaza omsakazo. Basebenzisa isitholi sokubuka ukuze bahlukanise okuthile okuqondiwe. Uma ubheka isithombe, uzobona ukuthi i-laser radar ephathwayo inamalensi amabili. Encane iyilensi yokudlulisa, ekhipha amaza okukhanya, kuyilapho enkulu ithola amagagasi avela kulokho okuqondiwe. Uzoqonda ukuthi kungani lokhu kubalulekile ngesekhondi.
Engikuthanda kakhulu nge-laser ukuthi isikhulu kufanele siyiphathe njengesikhali. Lokho kusho ukuthi kufanele izinze, ikwazi ukuphokophela, futhi kufanele ikwazi ukuthola indawo ekhanyayo emotweni yakho ukuze ithole isignali emuva.
Empeleni, iphoyisa kufanele liqonde izibani zangaphambili, ipuleti lelayisense, noma enye indawo ecwebezelayo noma ekhanyayo yemoto yakho. Le vidiyo ibonisa lokho iphoyisa elikubonayo ngesitholi sokubuka lapho liqondise umtshina we-laser emotweni lisebenzisa amachashazi ahlosiwe.
Njengoba amalaser alawulwa yi-FDA, lawa madivayisi kufanele abe amalaser Ekilasi 1. Lesi yisigaba esifanayo nezikhombisi ze-laser ezijwayelekile. Kalula nje, umtshina we-laser uyisikhombi se-laser. Kumele zivikeleke emehlweni, ngakho amandla azo aphansi, futhi inani lemisebe elibuyiselwe ku-radar yamaphoyisa liphansi ngokulinganayo.
Ngaphezu kwalokho, ngenxa yemithetho ye-FDA, lawa madivaysi anqunyelwe imvamisa yamaza awo okukhanya, esebenzisa i-laser ye-infrared enobude obungamaza angama-904 nanometer. Lena i-laser beam engabonakali, kodwa okuphawuleka nakakhulu ukuthi inobude obujwayelekile obujwayelekile.
Lokhu ukuphela kwezinga elivunyelwe, amadivayisi alisekelayo anamandla aphansi, futhi mina nawe singawathenga futhi.
(29:40) Ake sikhumbule ukuthi yiziphi izinyathelo ze-radar? Isivinini. Kodwa i-laser ayilinganisi isivinini, ikala ibanga. Manje ngikubonisa isilayidi esibaluleke kakhulu futhi ngikunikeza isikhathi sokubhala le fomula emangalisayo: isivinini silingana nebanga elihlukaniswa nesikhathi. Ngibone ukuthi kukhona oze wathatha isithombe salesi slide (uhleko ezilalelini).
Into ewukuthi, lapho izibhamu ze-laser zikala ibanga, zikwenza lokho ngemvamisa ephezulu kakhulu, ngokuvamile izilinganiso eziyi-100 kuye kwezingama-200 ngomzuzwana. Ngakho-ke, ngisho nangemva kokuba umtshina we-radar uvaliwe, isibhamu se-laser siyaqhubeka nokukala isivinini sakho.
Ungabona isilayidi esibonisa ukuthi ezingxenyeni ezimbili kwezintathu zezwe lethu, ukusetshenziswa kwama-laser jammers kuthathwa njengokusemthethweni ngokuphelele - lezi zifunda zigqanyiswe ngokuluhlaza kumephu. Amazwe lapho ukusetshenziswa kwalawa madivayisi kungekho emthethweni aboniswa ngombala ophuzi, futhi angikwazi nje ukucabanga ukuthi isihogo siqhubeka eVirginia, lapho yonke into ivinjelwe (uhleko ezilalelini).
( 31:10 ) Ngakho, sinezinketho ezimbalwa. Esokuqala ukusebenzisa imoto enamalambu afihliwe kumodi ethi "show-and-hide". Ayisebenzi kahle kakhulu, kodwa iyahlekisa futhi izokwenza kube nzima kakhulu ukuthi isikhulu sikukhombe.
Inketho yesibili ukusebenzisa i-laser cannon yakho! Ukuze senze lokhu, sidinga ukwazi ukuthi kusebenza kanjani. Ngaphambi kokuthi siqale, ngizokukhombisa izibonelo ezithile zesikhathi. Izikhathi esizoxoxa ngazo azisebenzi kuwo wonke amarada e-laser akhona, kodwa asebenza kumvamisa awasebenzisayo. Uma usuqonda ukuthi zisebenza kanjani, uzoqonda ukuthi ungayihlasela kanjani i-radar ye-laser ngayinye, ngoba konke kuza ngesikhathi.
Ngakho-ke, amapharamitha abaluleke kakhulu ububanzi be-pulse, okungukuthi i-laser ihlala isikhathi eside kangakanani, nesikhathi somjikelezo, okuwukuthi ivutha kangaki. Lesi silayidi sibonisa ububanzi bokushaya kwenhliziyo: 1, 2, 3, 4, 5 – pulse-pulse-pulse-pulse-pulse—lokho ububanzi beshayela. Futhi isikhathi somjikelezo, okuyisikhawu sesikhathi phakathi kwama-pulses amabili, singama-5 ms.
Uzoqonda yonke into ngomzuzwana, kodwa le ngxenye ibaluleke ngempela. Lapho isibhamu se-laser sithumela uchungechunge lwama-pulses, yini esiyilindele ekuphenduleni? Isiphi isici somzimba efuna ukusikala? Kulungile, ibanga! Ukushaya kwenhliziyo kukala ibanga. Ngakho-ke uma imoto yakho ishaywa ukushaya kwenhliziyo yokuqala futhi iphindela emuva, ingabe lokho kusho ukuthi isikhulu siqophe isivinini sakho? Cha, uyakwazi nje ukusho ukuthi ukude kangakanani naye. Angakwazi kuphela ukubala isivinini sakho ngokuthola isignali ebonisiwe kusuka ku-pulses yesibili, yesithathu, kanye nelandelayo. Ungabona ukuthi izikhawu zesikhathi phakathi kwe-pulse ekhishiwe kanye nokubonisa kwayo okwamukelwe zishintsha kanjani ngebanga: amafidi angu-1 000, amafidi angu-800, amafidi angu-600, amafidi angu-400—lapho imoto iseduze, sifushane isikhawu sesikhathi phakathi kwama-pulses akhishiwe nabonisiwe. Lezi zinguquko yizona ezivumela ukubala isivinini sakho. Yingakho bethatha izilinganiso eziningi kangaka ngomzuzwana—i-100 noma ngisho nama-200—ukuze banqume isivinini sakho ngokushesha okukhulu.
Ake sandise ibanga phakathi kwama-pulses ngamanye futhi sikhulume ngezinye izindlela zokulwa. Ngakho-ke, le migoqo ebomvu imele ukushaya kwesibhamu se-laser: i-pulse-pulse-pulse. Ama-pulse amathathu esewonke. Amabha awolintshi ayimifanekiso ebuyayo ye-pulse ngayinye. Phakathi kwama-pulse amabili akhishiwe, sine-"window" engu-5-ms lapho okwethu okubonisiwe kwe-pulse kubuya khona. Sikalani? Kulungile, ibanga! Asilinganisi isivinini ngokuqondile.
Ngakho uma sibuyisela ukushaya kwenhliziyo yethu ngaphambi kokubuya kwenhliziyo yangempela, ebonisiwe, singabonisa i-radar ukuthi sikude kangakanani. Engizokubonisa kona ngokulandelayo ukuhlasela kwe-brute-force okujwayelekile.
Cabanga ushayela uzulazule wazi kahle ukuthi i-laser ekushaya imvamisa engakanani—i-millisecond engu-1 ku-904 nm. Umbono wukuthi ngokufaka amasiginali ethu esikhundleni sesiginali ye-laser, sitshela amaphoyisa ukuthi sikude elithile. Angisitsheli isibhamu serada ukuthi ngihamba amamayela ayizigidi ezingama-97 ngehora; Ngiyikhohlisa ukuze ngicabange ukuthi ngiseduze ngempela, njengokuhamba ngamafidi angu-100. Isignali yokuqala iyitshela ukuthi ngiqhele ngamafidi angu-100, bese isignali yesibili iyitshela ukuthi ngikude ngamafidi angu-100 futhi, bese okwesithathu ikutshela ukuthi ngikude ngamamitha angu-100 futhi, njalo njalo. Kusho ukuthini lokho? Ngihamba ngesivinini esinguziro!
Kuma-radar amaningi e-laser emakethe, ukusebenzisa le ndlela kubangela umlayezo wephutha. Ukuhlasela okulula kwe-brute-force kusetshenziswa ukushaya kwe-millisecond kuphumela kumlayezo wephutha lokulinganisa ovela kusikrini se-radar.
( 35:10 ) Kunezinto eziningana ezisivumela ukuba simelane nezinyathelo zokuphikisa, sizokhuluma ngalokho ngomzuzwana. Ezinye zezibhamu ze-laser ezintsha kakhulu ziyakwazi ukubona ukuthi ngithumele i-pulse eyodwa futhi ngathola ezine ngokubuyisela. Ukuze balwe nokuphazamiseka, basebenzisa i-laser shifting, okusho ukuthi bashintsha ububanzi be-pulse ukuze ukushaya kwenhliziyo okubonisiwe kulingane nebanga elingaphazanyiswa amasiginali mbumbulu, ahlanekezelwe. Kodwa nathi singakuphikisa lokhu. Uma sesiqonda ukuthi i-pulse ekhishiwe ishintshelwa kuphi—okungukuthi, ukuthi kuyini ukushintsha kwe-laser—singagudluza ama-pulse ethu abonisiwe siye ohlangothini olufanayo. Okuthakazelisayo ukuthi ukwazi ububanzi be-pulse kanye nesikhathi, singakwazi ukubona isibhamu se-laser nge-pulse yesibili.
Ngemva kokuthola umfutho wokuqala, ngokushesha sisebenzisa amandla anonya, sithola umfutho wesibili, futhi sinqume ngokunembile ukuthi yisiphi isibhamu esinaso emehlweni aso, ngemva kwalokho sisebenzise izinyathelo zokuphikisa. Ngizobachazela ngokushesha ukuthi bayini.
Amabha abomvu kuslayidi amelela ama-pulses akhishiwe erada ye-laser, amabha awolintshi amelela ukubonakaliswa kwawo kwesithiyo esinyakazayo, futhi amabha aluhlaza amele ama-pulses esibuyela kule radar.
Esingakwenza nje ukushintsha ama-pulses we-laser yethu. Sinewindi lama-millisecond angu-5 ukuze sithumele ama-pulses abuyisiwe, futhi okokuqala, sidinga ukubuyisela isignali yokuqala eyamukelwe ebangeni elingamamitha angu-600 ukusuka ku-radar. Lapho sithola i-pulse yesibili, sinquma ukuthi iyiphi i-radar eyithumele futhi sazi kahle ukuthi ubani osiqondise. Singabe sesisebenzisa izinyathelo eziphikisanayo futhi sibike ukuthi sikude kakhulu, sithi, amafidi angama-999. Lokhu kusho ukuthi sizobe sisuka kude ne-radar esitholile. Ngale ndlela, singakwazi ukumelana namamodeli amaningi we-laser radar. Ama-laser jammers ezohwebo enza okufanayo. Kunamathuluzi ambalwa anjalo emakethe atholakala kalula futhi asebenzisa izinyathelo ezifanayo zokuphikisa. Qaphela ukuthi lezi zisetshenziswa zitholakala kalula.
(37:20). Несколько лет назад я создал устройство под названием COTCHA. Это ESP 8266, основанный на принципе взлома по Wi-F и построенный на платформе Arduino. Это очень удачное решение, на основе которого можно создавать другие хакерские электронные устройства. Сейчас я хочу представить вам более серьезное устройство под названием NOTCHACOTCHA. Это лазерная «глушилка» на основе ESP 8266, использующая 12В питание, что позволяет легко установить ее в автомобиле. Это устройство использует режим брутфорс для светового излучения с длиной волны 940 нм, то есть выдает импульсы с частотой 1 мс. Оно соединяется со смартфоном с помощью модуля беспроводной связи и может использоваться совместно с Android-приложением. В некоторых штатах использование этой «глушилки» абсолютно законно.
Le "jammer" ibhekana no-80% wama-laser radar asetshenziswayo, kodwa ayikwazi ukumelana nezinhlelo ezithuthukile njenge-Dragon Eye, amaphoyisa azisebenzisayo njengesinyathelo sokulwa namandla anonya.
Ngaphezu kwalokho, senza lawa ma-jammer abe umthombo ovulekile, njengoba izinguqulo zezentengiso zamadivayisi afanayo zikhona, futhi kulula ngathi ukuzihlehlisa-sizenze ubunjiniyela. Ngakho-ke, kusemthethweni kwezinye izifundazwe—uyakhumbula lezo zindawo eziluhlaza kumephu yase-US? Ngeshwa, ngikhohliwe ukufaka iColorado phakathi kwezifunda "eziluhlaza", lapho ama-laser jammers nawo asemthethweni.
I-NOTCHACOTCHA iphinde isebenze kumodi yokulingisa i-laser radar, ikuvumela ukuthi uhlole amanye ama-jammer, ama-radar detectors, nokunye. Le divayisi iphinde isekele imodi ye-MIRT, evumela amarobhothi aluhlaza, kodwa lowo umbono omubi ngempela. Cishe akufanele ukwenze lokho (ukuhleka).
Ngizokutshela ukuthi i-NOTCHACOTCHA iyinkululeko, futhi ngayo, singalawula noma iyiphi isistimu esiqondise kithi. Ngizochaza ngokushesha izinto ezisetshenziswa ukuhlanganisa le jammer. Imodeli ye-D1 mini ye-ESP 8266, ebiza u-$1.50, i-resistor engu-2,2kΩ ebiza amasenti angu-3, i-3,3V voltage converter ngamasenti angu-0.54, i-TIP 102 transistor ngamasenti angu-0.8, kanye nephaneli ye-LED ekhipha ubude begagasi obungu-940nm. Lena ingxenye ebiza kakhulu yedivayisi, ebiza u-$6. Isamba sezindleko ngu-$8 (ihlombe elivela ezithamelini).
Ungalanda uhlu lwezinto zokwakha, amakhodi, neminye imibono embalwa “emibi” kusixhumanisi. , konke lokhu kusezindaweni zomphakathi. Bengifuna ukuletha i-jammer enjengaleyo lapha; Nginayo, kodwa ngiyiphule izolo ngesikhathi ngilungiselela ukwenza kwami.
Ukumemeza okuvela ezithamelini: "Bill, uyanya!"
Ngiyazi, ngiyazi. Ngakho-ke, le nto ingumthombo ovulekile, futhi imodi ye-brute-force isebenza kahle. Ngikuhlolile lokho ngoba ngihlala eKansas, lapho konke kusemthethweni.
Ngifuna nazi ukuthi umzuliswano wokuqala lo. Ngizoqhubeka nokuthuthukisa ikhodi, futhi ngingalubonga kakhulu usizo lwakho ekudaleni i-laser jammer yomthombo ovulekile engaqhudelana nozakwabo bezentengiso. Ngiyabonga kakhulu, bafo, sibe nesikhathi esihle, futhi ngikwazisa kakhulu!
Ezinye izikhangiso 🙂
Siyabonga ngokuhlala nathi. Uyazithanda izindatshana zethu? Ufuna ukubona okuqukethwe okuthakaselayo okwengeziwe? Sisekele ngokufaka i-oda noma ngokuncoma kubangani, , i-analogue ehlukile yamaseva ezinga lokungena, esungulwe yithi ngenxa yakho: (itholakala nge-RAID1 kanye ne-RAID10, kufika kuma-cores angu-24 kuze kufike ku-40GB DDR4).
