Phakamisa izandla zakho ukuba uyazi ukuba oku kunokukhokelela entwenini! Kulungile, konke oku kunomdla, kodwa ukuba ujonga ngakumbi kumzekelo we-65 mph, uya kuqaphela ingxaki encinci. Isixhobo sam sithumela rhoqo esi santya kuba sisebenza kumaza athile amiselweyo, kodwa kuthekani ukuba ndiqhuba ndidlula esikolweni apho isantya sisebenza khona? Ukongeza, asinakuze sazi ngokuthe ngqo ukuba yeyiphi na irada yamapolisa ehambisa umqondiso.
Nangona kunjalo, bahlobo, manditsho ukuba siphila kumaxesha anomdla. Siphila kwixesha elizayo apho lonke ulwazi lwehlabathi lusezandleni zethu kwaye sinokwenza nantoni na esiyifunayo ngalo. Izichongi zerada yemoto entsha, ngakumbi iValentine One kunye ne-Escort 360, zibhaqa imiqondiso ye-radar ebekwe malunga neekhilomitha ezi-2-3 phambi kwemoto yakho kwaye, usebenzisa iBluetooth, bonisa ulwazi kwiscreen ukuba iradar yamapolisa ikhupha kangaphi loo miqondiso (ihlombe) .
Ndizakunqumama okomzuzwana ndivakalise umbulelo wam ku-Tri Wolfe, ohleli apho, ngokundinika indawo elunge kakhulu yokuqhuba uvavanyo, ngokusemthethweni nangokusemthethweni ngokupheleleyo.
(23:50) Ke, konke ekufuneka sikwenzile kukudala isicelo esisixelela umda wesantya sangoku, njengetrafikhi API. Isizukulwana sanamhlanje se-radar detectors sibona ngokugqibeleleyo ukuphindaphinda kwamaza e-radar yamapolisa kumgama ongangeekhilomitha ezi-2. Ukusuka koku ungabala umlinganiselo wangoku wesantya apho isithuthi sakho kufuneka sihambe ngaso kunye namaxesha omqondiso obonisa esi santya.
Ekuphela kwento esiyifunayo yiprosesa encinci kakhulu. Kwisilayidi ubona i-ESP 8266 microcontroller, yanele ngokwaneleyo. Nangona kunjalo, ingxaki kukuba i-SDRs, okanye i-software echazwe iirediyo, ezikhoyo namhlanje azisebenzi kule ndawo ephakamileyo okanye i-microwave space, yenzelwe i-spectrum ephantsi-frequency. Kodwa ukuba uthatha i-hardware ngokungathí sina, unokuhlanganisa isixhobo esisidingayo malunga nama-700 eerandi. Ngaphezu koko, uninzi lwale mali iya kuba yindleko yokuphucula i-SDR yosasazo oluhamba rhoqo.
(25:10) Noko ke, iFCC ayifuni ukuba wenze oku. Ukusebenzisa isixhobo sokuphazamisa i-radar lulwaphulo-mthetho oluhlawuliswa i-50 yeedola okanye iminyaka emi-5 entolongweni, okanye zombini. I-radar jammers ibingekho semthethweni e-United States ukusukela ngo-1996, isenza nabani na osebenzisa okanye othengisa ezi zixhobo abe sisikrelemnqa.
IKomishoni yoNxibelelwano lwe-Federal ithatha oku nzulu kangangokuba awuvumelekanga nokuba upapashe ezi zixhobo okanye ukukhuthaza ukusetyenziswa kwazo. Ukuba usijongisisa esi sixhobo seedola ezingama-700, uya kubona ukuba asisibizi kangako. Kodwa ukwazi ukwenza i-radar jammer, siyenza ifikeleleke, kwaye ke unokwenza isigqibo esifanelekileyo - ukusisebenzisa okanye cha.
Ngoko, i-FCC ayiyi kusivumela ukuba sikhawulezise le nkqubo. Ke makhe sibone ukuba ngawaphi amanyathelo okuthintela asebenzayo nasemthethweni akhoyo kuthi? Zikhona kwaye zimelwe zizinto ezifumaneka esidlangalaleni. Ukuba awunalo ithuba lokusebenzisa i-radio-electronic radar detectors, sebenzisa ezinye izixhobo, ukhetho lwabo lukhulu kakhulu.
Izichongi zerada zala maxesha i-Uniden R3/R7, i-Escort Max360, iRadenso Pro M okanye iValentine One w/BT ibamba ngokugqibeleleyo nakuphi na ukukhutshwa kwerediyo, onke la maza erediyo abonakalisiweyo kwaye athe ngqo, kumgama ongangeemayile ezi-2, kodwa azikwazi kwaphela ukubona laser. Nangona kunjalo, abantu abaninzi bayazi ukuba amapolisa asebenzisa iilaser njengesixhobo sokulinganisa isantya. Kwaye apha sinekroba! Inyani yeyokuba ukulawulwa kokusetyenziswa kwezixhobo zokukhanya, oko kukuthi, izixhobo ezikhupha ukukhanya, eziyilaser, azikho nangaphakathi kwe-FCC - lilungelo le-FDA, i-Food and Drug Administration. Ngoko makubekho ukukhanya!
Kuyavela ukuba le mipu ye-laser yahluke kakhulu kubazala babo bamaza kanomathotholo. Basebenzisa isikhangeli ukugqamisa into ekujoliswe kuyo. Ukujonga umfanekiso, uya kubona ukuba irada yelaser ephathwayo ineelensi ezimbini. Incinci yi-lens yokudlulisa ekhupha amaza okukhanya, kwaye lens enkulu isetyenziselwa ukufumana amaza abonakaliswe kwithagethi. Ngomzuzwana uya kuqonda ukuba kutheni le nto ibalulekile.
Eyona nto ndiyithanda kakhulu ngelaser kukuba igosa kufuneka liyiphathe njengesixhobo. Oko kukuthi, esi sixhobo kufuneka sizinzile, kufuneka sikuvumele ukuba ujonge kwaye ufumane indawo ebonakalisayo kwimoto yakho ukuze ufumane umqondiso.
Ngapha koko, ipolisa kufuneka lijolise kwizibane eziphambili, ipleyiti yelayisensi, okanye enye indawo emenyezelayo okanye ekhanyayo yemoto yakho. Le vidiyo ibonisa into ebonwa ligosa ngesikhangeli xa lijolise kwisixhobo sokubona i-laser kwimoto esebenzisa ireticle ekhanyisiweyo.
Ngenxa yokuba iilaser zilawulwa yi-FDA, ezi zixhobo kufuneka zibe yiClass 1 lasers. Ukubeka nje, i-laser detector iyafana ne-laser pointer. Kufuneka bakhuseleke emehlweni, ngoko amandla abo aphantsi kakhulu, kwaye isixa semitha ebuyiselwe kwi-radar yamapolisa sincinci ngokulinganayo.
Ukongeza, enkosi kummiselo we-FDA, ezi zixhobo zilinganiselwe kumaza okukhanya, zisebenzisa i-laser ye-infrared ene-wavelength ye-904 nanometers. Ngumqadi welaser ongabonakaliyo, kodwa eyona nto iphawuleka ngakumbi kukuba ngumqa we-wavelength oqhelekileyo.
Lo ngumgangatho ovunyelweyo kuphela, izixhobo eziwuxhasayo zinamandla aphantsi, kwaye mna nawe sinokuzithenga.
(29:40) Masikhumbule ukuba yintoni imilinganiselo yerada? Isantya. Kodwa i-laser ayilinganisi isantya, ilinganisa umgama. Ngoku ndikubonisa isilayidi esibaluleke kakhulu kwaye ndikunika ixesha lokubhala le fomula imangalisayo: isantya silingana nomgama owahlulwe ngexesha. Ndiqaphele ukuba kukho umntu ode wafota esi silayidi (kwahleka kubaphulaphuli).
Ingongoma kukuba xa imipu yelaser ilinganisa umgama, ikwenza oko ngesantya esiphezulu kakhulu, ngokuqhelekileyo i-100 ukuya kuma-200 imilinganiselo ngomzuzwana. Ke ngelixa i-radar detector sele icinyiwe, umpu we-laser uyaqhubeka nokulinganisa isantya sakho.
Uyabona isilayidi esibonisa ukuba kwi-2/3 yommandla welizwe lethu ukusetyenziswa kwe-laser jammers kuthathwa njengomthetho ngokupheleleyo - ezi ndawo zigxininiswe eluhlaza kwimephu. Umbala ophuzi ubonisa amazwe apho ukusetyenziswa kwezi zixhobo kungekho mthethweni, kwaye andinakukwazi ukucinga ukuba yintoni isihogo esenzeka eVirginia, apho yonke into inqatshelwe (ukuhleka kubaphulaphuli).
( 31:10 ) Ngoko sinezinto ezimbini esinokukhetha kuzo. Inketho yokuqala kukusebenzisa imoto enezibane ezifihliweyo kwimodi "yomboniso kunye nokufihla". Ayisebenzi kakhulu, kodwa iyahlekisa kwaye iya kwenza kube nzima kakhulu ukuba igosa lijolise kuye.
Inketho yesibini kukusebenzisa umpu wakho welaser! Ukwenza oku kufuneka siyazi ukuba isebenza njani. Ngaphambi kokuba siqale, ndiza kukubonisa imizekelo yexesha. Amaxesha esiza kuthetha ngawo awasebenzi kuzo zonke iirada zelaser ezikhoyo, kodwa ayasebenza kumaxesha asetyenziswayo. Nje ukuba uqonde indlela asebenza ngayo, uya kuqonda ukuba ungahlasela njani irada nganye yelaser, kuba yonke into yehla kumbandela wexesha.
Ke, iiparamitha ezibaluleke ngakumbi bububanzi be-pulse, oko kukuthi, ixesha elide kangakanani i-laser ivuliwe, kunye nexesha lomjikelo, oko kukuthi, ivutha kangaphi. Esi silayidi sibonisa ububanzi be-pulse: 1,2,3,4,5 - i-pulse-pulse-pulse-pulse-pulse-pulse, yiloo nto ububanzi be-pulse. Kwaye ixesha lokujikeleza, oko kukuthi, ixesha lexesha phakathi kwee-pulses ezimbini, ngu-5 ms.
Uya kuqonda ngomzuzwana, kodwa le nxalenye ibaluleke ngokwenene. Xa umpu we-laser uthumela uthotho lwee-pulses, ulindele ntoni njengempendulo? Luluphi uphawu lomzimba afuna ukuluzuza? Injalo, umgama! Impembelelo ilinganisa umgama. Ngoko xa imoto yakho ibetha impembelelo yokuqala kwaye ibuya, ngaba oko kuthetha ukuba igosa lirekhode isantya sakho? Hayi, unokufumanisa kuphela ukuba ukude kangakanani kuye. Uyakwazi ukubala isantya kuphela ngokufumana umqondiso obonakalisiweyo wesibini, wesithathu kunye ne-pulses elandelayo. Uyakwazi ukubona indlela izithuba zexesha phakathi kwe-pulse ekhutshiweyo kunye nembonakalo yayo efunyenweyo eguqukayo kunye nomgama: iinyawo ze-1000, i-800 yeenyawo, i-600 yeenyawo, i-400 yeenyawo-imoto ekufutshane, i-short interval yexesha phakathi kweempembelelo ezikhutshiweyo kunye nezibonakalisiweyo. Ukutshintsha ezi parameters kukuvumela ukubala isantya semoto yakho. Yiyo loo nto bethatha imilinganiselo emininzi kangaka ngesekhondi - 100 okanye nokuba ngama-200 - ukumisela ngokukhawuleza isantya sakho.
Masiwunyuse umgama phakathi kwee-pulses zomntu ngamnye kwaye sithethe malunga nemilinganiselo ethile. Ke, le mivalo ibomvu imele iipulses ezikhutshwa ngumpu welaser: pulse-pulse-pulse. Iipulses ezi-3 kuphela. Imivalo e-orenji yimbonakaliso ebuyisiweyo ye-pulse nganye. Phakathi kwee-pulses ezimbini ezikhutshiweyo sine-5 ms ububanzi "ifestile" apho eyethu ibonakalisa i-pulse returns. Silinganisa ntoni? Injalo, umgama! Asilinganisi isantya ngokuthe ngqo.
Ngoko ukuba sibuyisele impembelelo yethu ngaphambi kokuba i-ipulse yokwenene, ebonakalisiweyo ibuye, sinokubonisa irada ukuba sikude kangakanani kuyo. Into endiza kukubonisa yona ngokulandelayo yindlela eqhelekileyo ye-brute force.
Khawube nomfanekiso wakho uqhuba ujikeleza usazi kakuhle ukuba i-laser ikubetha kangakanani na-1 millisecond kwi-904 nm. Umbono kukuba ngokutshintshela umqondiso we-laser obonakalisiweyo kunye neempawu zethu, sibonisa amapolisa ukuba sikumgama othile kubo. Andiyixeleli irada ukuba ndihamba nge-97 yezigidi zeemayile ngeyure, hayi, ndenza ukuba icinge ukuba ndisondele kakhulu, ngathi ziinyawo ezili-100 kude. Umqondiso wokuqala uthi ndikude ngeemitha ezili-100, emva koko umqondiso wesibini uza kuwo, ophinda uthi ndikude ngeemitha ezili-100, emva koko owesithathu uthi iinyawo ezili-100 kwakhona, njl. Ingaba ithetha ntoni? Ukuba ndihamba ngesantya esingu-zero!
Uninzi lweerada ze-laser kwimarike, ukusebenzisa le ndlela kubangela umyalezo wempazamo. I-brute force elula ngendlela ye-millisecond pulse ibangela ukuba umyalezo wempazamo yokulinganisa uvele kwisikrini se-radar.
( 35:10 ) Kukho izixhobo ezininzi ezikuvumela ukuba usebenzise amanyathelo achasene nemilinganiselo, siza kuthetha ngaloo nto ngomzuzwana. Eminye yemipu emitsha yelaser inokubona ukuba ndithumele ipulse enye kwaye ndafumana i-4 ngembuyekezo, zisebenzisa i-laser shifting, oko kukuthi, ziya kutshintsha ububanzi be-pulse ukuze i-pulse eyinyani ebonakalisiweyo ilingane kuluhlu. zichatshazelwe ziimpawu ezigqwethekileyo. Kodwa nathi sinokuyixhathisa le nto. Nje ukuba siqonde apho i-pulse ekhutshiweyo itshintshelwe khona, oko kukuthi, lithini ixabiso lokutshintsha kwelaser, sinokutshintsha iipulse zethu ezibonisiweyo apho. Into enomdla kukuba ukwazi ububanzi be-pulse kunye nexesha, sinokuchonga umpu we-laser nge-pulse yesibini.
Emva kokuba sifumene impembelelo yokuqala, ngokukhawuleza sisebenzisa indlela ye-brute force, sifumana i-inpulse yesibini kwaye sinqume ngokuchanekileyo ukuba yeyiphi isibhamu esijoliswe kuyo, emva koko sinokusebenzisa amanyathelo okuphikisana nawo. Ndiza kukuxelela ngokukhawuleza ukuba ziyintoni na.
Imivalo ebomvu kwisilayidi imele i-pulses ekhutshweyo ye-laser radar, i-orenji yimbonakaliso yazo evela kumqobo ohambayo, kwaye eziluhlaza zii-pulses esizibuyisela kule radar.
Ekuphela kwento esinokuyenza kukwahluka imibhobho yelaser yethu. Sinefestile ye-5 ye-millisecond yokuthumela i-pulses ebuyisiweyo, kwaye into yokuqala ekufuneka siyenze kukubuyisela uphawu lokuqala olufunyenwe kwii-600 ezinyaweni ukusuka kwi-radar. Emva kokuba sifumene impembelelo yesibini, sifumanisa ukuba luhlobo luni lwerada oluyithumeleyo kwaye sifumanise ukuba ngubani kanye osijongileyo. Singasebenzisa amanyathelo achaseneyo kwaye sixele ukuba sikude kakhulu, njenge-999 yeemitha kude. Oko kukuthi, ngokumalunga ne-radar esibhaqileyo, siya kuhamba. Ngale ndlela sinokulwa neemodeli ezininzi ze-laser radar. Iijammer ze-laser zorhwebo zenza into efanayo. Kukho isibini sezixhobo ezinjalo kwimarike enokuthengwa ngokukhululekileyo ezalisekisa imilinganiselo efanayo. Gcina nje ukhumbule ukuba ezi zixhobo ziyafumaneka.
(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" inokusingatha i-80% yeerada zelaser ezisetyenziswayo, kodwa ayikwazi ukumelana neenkqubo eziphambili ezifana ne-Dragon Eye, esetyenziswa ngamapolisa njengenyathelo lokuchasa umkhosi okhohlakeleyo.
Ukongeza, senza ezi jammers zibe ngumthombo ovulekileyo, kuba kukho iinguqulelo zorhwebo zezixhobo ezifanayo, kwaye akunzima kuthi ukuba sisebenzise ubunjineli bokubuyisela kubo. Ngoko ke kusemthethweni kwamanye amazwe, khumbula iindawo eziluhlaza kwimephu US? Ngendlela, ndilibale ukubandakanya iColorado phakathi kweendawo "eziluhlaza", apho ukusetyenziswa kwe-laser jammers kuvunyelwe kwakhona.
I-NOTCHACOTCHA ikwasebenza kwimowudi yokulingisa i-laser radar, ikuvumela ukuba uvavanye ezinye iijammers, ii-radar detectors, njalo njalo. Kwakhona, esi sixhobo sixhasa imo ye-MIRT kuquka ukukhanya okuluhlaza, kodwa lo ngumbono ombi kakhulu. Mhlawumbi, akufanele wenze oku (ukuhleka kubaphulaphuli).
Ndiza kukuxelela ukuba i-NOTCHACOTCHA yinkululeko, kungenxa yoncedo lwayo ukuba singakwazi ukulawula nayiphi na inkqubo ejoliswe kuthi. Ndiza kuthetha ngokukhawuleza malunga nezixhobo apho le "jammer" ihlanganiswe khona. Le yi-ESP 8266 imodeli ye-D1 mini, ebiza idola enye enesiqingatha, i-2,2 kOhm resistor exabisa i-3 cent, i-3,3 V yokuguqula i-voltage ye-54 cent, i-TIP 102 i-transistor ye-8 cent kunye nepaneli ye-LED yokukhutshwa kokukhanya okukhanyayo kunye ubude bobude be-940 nm. Nge-6 yeedola, le yeyona nxalenye ibiza kakhulu yesixhobo. Ngokubanzi, konke oku kubiza i-$ 8 (ihlombe elivela kubaphulaphuli).
Unokukhuphela uluhlu lwezixhobo, iikhowudi kunye nezinye iingcamango ezininzi "ezimbi" kwikhonkco , konke oku kukwindawo yoluntu. Ndandifuna ukuzisa "i-jammer" enje apha, ndinayo, kodwa izolo ndiyiphule ngelixa ndihlaziya ukusebenza kwam.
Khwaza kubaphulaphuli: “Bill, uyanya!”
Ndiyazi, ndiyazi. Ke le nto ingumthombo ovulekileyo kwaye imowudi ye-brute force isebenza kakuhle. Ndiyijongile le nto kuba ndihlala eKansas kwaye yonke into isemthethweni apho.
Ndifuna wazi ukuba lo ngumjikelo wokuqala kuphela. Ndiya kuqhubeka ndiphuhlisa ikhowudi, kwaye ndiya kuba nombulelo kakhulu ngoncedo ekudaleni i-laser jammer evulekileyo enokukhuphisana ne-analogues yorhwebo. Enkosi kakhulu bafo, sibe nexesha elimnandi kwaye ndiyayibulela kakhulu!
Ezinye iintengiso 🙂
Enkosi ngokuhlala nathi. Ngaba uyawathanda amanqaku ethu? Ngaba ufuna ukubona umxholo onomdla ngakumbi? Sixhase ngokufaka iodolo okanye ngokucebisa abahlobo, , i-analogue eyodwa yeeseva zomgangatho wokungena, eyenzelwe wena: (ifumaneka nge-RAID1 kunye ne-RAID10, ukuya kuthi ga kwi-24 cores kunye ne-40GB DDR4).
