Ukukhokela: Wamkelekile wonke umntu kwinkomfa ye-DefCon ye-27! Kuba uninzi lwenu lulapha okokuqala, ndiza kukuxelela malunga nezinye zeziseko zoluntu lwethu. Enye yazo kukuba sithandabuza yonke into, kwaye ukuba uyeva okanye ubona into ongayiqondiyo, vele ubuze umbuzo. Inqaku elipheleleyo le-DefCon kukufunda into - ukusela, ukudibana nabahlobo, ukwenza izinto ezibudenge.
Luhlobo lwamava endingazange ndiwaqonde ngokupheleleyo de ndathetha nomhlobo kwiminyaka emibini okanye emithathu eyadlulayo. Wathi ngeli xesha endaweni yokuthumela iqela lakhe kwinkomfa ye-BlackHat, wagqiba ekubeni abathumele kwi-DefCon. Ndambuza ukuba yintoni umahluko? Umhlobo waphendula ukuba uneqela elihle kakhulu, elihlakaniphile nelinamava, kwaye uyabathumela kwi-BlackHat ukuze abenze bahlakaniphe kancinci, njengokuba usenza ngemela elibukhali, ukuhlaziya ukulola. Kodwa xa ebathumela kwiDefCon, ufuna ukuba babe ngabantu abacinga ngcono. Ndathi, βThixo, mandicinge ngale nto!β Ngokwenene le yindawo apho abantu beza kufunda khona.
Uyazi ukuba kukho uluvo olungekho semthethweni - ukuba ubandakanyeka kukhuseleko lolwazi, hlala kude ne-hacking. I-Infosecurity yindawo enhle yokusebenza, ukwenza imali, kodwa ukufumana imali kunye nokukwazi ukuyifumana kuhluke kuvuyo lomhloli, ulonwabo lwezinto ezifunyenwe ezingalindelekanga, ukuxazulula iingxaki kunye nokufumana ukungaphumeleli. Ukungaphumeleli ukuba akufanele uloyike, kuba apha ujikelezwe ngabahlobo. Ndicinga ukuba lo ngumahluko - kuba ukuba usebenza nje kukhuseleko lolwazi, kuya kufuneka woyike ukusilela.
UJoe Grand: Enyanisweni, ukusebenza kwi-Infosec akukwenzi ube yi-hacker, kwaye ukuba uyi-hacker, oko akuthethi ukuba ubandakanyeka kukhuseleko lolwazi! Ihlabathi lokugqekeza lingaphezulu kokhuseleko lolwazi.
Ukukhokela: ewe, kwaye siyazama ukuyamkela. Ukuba uyakhumbula, kunyaka ophelileyo sabamba i-DefCon e-China njengovavanyo. Esi yayisisihlandlo sokuqala ukuba le nkomfa ibanjelwe ngaphandle kwelaseUnited States. Yaba sesona siganeko sikhulu sokhuseleko se-IT sokuqhekezwa kwamaTshayina ngaloo nyaka. Ibali elinika umdla lenzeka apho. Xa ndabuza ukuba yimalini esifanele siyihlawule kwinkomfa, saxelelwa, "akukho mntu ubiza nantoni na kwiinkomfa, yindleko yokuthengisa, ngoko ke simahla." Xa ndibuza ukuba inkomfa ifanele ibanjwe ngeempelaveki ukuze itsale abafundi abaninzi okanye ngcono phakathi evekini ukutsala abameli beenkampani, saxelelwa ukuba akukho mntu wakhe wabamba iinkomfa ngeempelaveki ngaphambili. Ndatsho ukuba sifuna ukuza neeT-shirts zeDefCon kunye nathi kwaye ndabuza ukuba baqhele ukuthengisa malini, bandixelela ukuba "akukho mntu uthengise i-T-shirts kwiinkomfa ngaphambili."
Emva koko saba ne-DefCon yethu yesibini e-China kwaye ndaya ku-Kingpin ndamcela ukuba enze into epholileyo, iibheji ezikhethekileyo ze-Defcon.
UJoe Grand: ewe, ubukholisa kakhulu, kwaye bekufuneka ibeyinto epholileyo, ngokuhambelana nondoqo weDefCon.
Ukukhokela: sasinombono wokwenza kungekhona ibheji elula, kodwa uhlobo oluthile lweteknoloji, ibheji ye-elektroniki, kwaye uJoe wathatha le ngcamango ngentshiseko enkulu kwaye wagqiba ekubeni enze into engaqhelekanga ngokupheleleyo, engazange yenziwe ngaphambili.
UJoe Grand: abantu abaninzi benza iibheji zibe yimisebenzi yokwenene yobugcisa, ngoko ndandithandabuza ukuba ndiza kukwazi ukwenza into efana neebheji zoluntu ezaqala ukubonakala kwiminyaka eyi-9 eyadlulayo kwi-DefCon 18. Ekuqaleni ndandikhathazeke kakhulu, kodwa ke ndacinga ukuba Bendizovele ndizenzele esam istayile ndingazami kukhuphisana namntu into ebendihlala ndiyenza abantu beyithanda.
Ukukhokela: Esinye sezizathu zokudala ezi bheji zehardware yayikukuba akukho kuluntu lweBlackHat okanye kwiDefCon andizange ndibone izakhono zokuqhekeza u-Kingpin nabanye abaninzi abanazo. Nangona kunjalo, ukuba sifuna ukuzikhusela kwizinto ezimbi ezifana neerobhothi okanye imisebenzi karhulumente eyimfihlo, kufuneka sibe nobuchule bokugqekeza. Yayiluhlobo lomzamo ofihlakeleyo wokutsala umdla woluntu lwethu kwi-Hacker hardware, kwaye siye saphumelela.
UJoe Grand: abantu abafumana iibheji ezinjalo, nokuba babonakala beyazi into abafanele bayenze ngazo, basaya kubuza imibuzo, yaye oku kuya ngandlelβ ithile kuvuse umdla wabo kwizinto ezinjalo.
Ukukhokela: Xa ndacela uJoe ukuba enze izikhonkwane zaseTshayina, sasifuna into entsha ngokupheleleyo.
UJoe Grand: Ndinesilayidi esibonisa imbali yokuvela kweempawu zethu. Ezantsi ngasekunene, unokubona i-China 1.0 Ibheji yenkomfa yokuqala yaseTshayina, eyibhodi yesekethe eguquguqukayo.
Le bheji yayibonisa uluntu lwethu njengomthi, amasebe awo afuzisela imisebenzi eyahlukeneyo, kwaye ii-LED zazidanyaza njengoko zigqitywa. Isebenzisa indawo elula yophuhliso lweRaspberry Pi onokuthi uyibhalele ikhowudi ngokulula. Kodwa yayiyinto eyenziwa luluntu lwethu, kwaye e-China yayiquka inkcubeko entsha ye-hacker. Kwafuneka sibachazele ukuba yintoni ibheji ye-elektroniki kunye nento eyenzayo, yayimangalisa kwaye indlela amaShayina athatha ngayo le nto yandikhuthaza ukuba ndiyilwe ibheji entsha kwinkomfa yesibini.
Ukukhokela: Ndicinga ukuba kwakunzima kakhulu ukwenza.
UJoe Grand: ewe, ngabavelisi aba-2 okanye aba-3 kuphela abavumileyo ukunkcunkca ngenxalenye eethe-ethe ngolo hlobo. Yibhodi encinci ebhetyebhetye, umshicileli ubuyela emva naphambili kuyo kwaye unokuyaphula ngokulula, ngoko ukwenza ezi bheji kwakubiza kakhulu. Uyabona ukuba iPCB ipeyintwe mhlophe, idyasi yepeyinti yongezwa kancinci kwaye yanika ibheji ukuqina.
Ngokuqinisekileyo, olu yayingelulo uhlobo oluthile lwempumelelo yobugcisa, kodwa kwasekuqaleni sasingafuni ukwenza iibheji eziqhelekileyo. Kukho ibali elinxulumene nenkangeleko nganye kuzo, enokufumaneka kwithala leencwadi lomxholo wemidiya yoluntu. Kancinci kancinci siye sazama ukwazisa itekhnoloji entsha, amacandelo amatsha kunye neendlela ezintsha zokuvelisa. Kwi-DefCon 18, emva koko ndaye ndayeka ukwenza ibheji, ibheji ye-aluminium ene-laser etching ngaphambili yaziswa. Ndikhumbula incoko yethu kwigumbi lasehotele xa kwakufuneka singenise ibheji engumzekelo ukuze yamkelwe libhunga lasekuhlaleni. Ndathi ngumbono onobungozi kwaye uthe, "Yintoni ke? Masiyizame sibone ukuba kwenzeka ntoni."
Ukukhokela: Kubekho neempazamo xa, umzekelo, iibheji zethu ze-elektroniki zonakaliswe ngexesha lokuziswa kwamanye amazwe. Kodwa masibuyele kwiibheji zaseTshayina- ngaba zixhotyiswe ngee-LED?
UJoe Grand: ewe, kwicala elingasemva lebhodi yesekethe eprintiweyo, kwaye xa zikhanyisa, ngenxa ye-substrate ekhethekileyo, ukukhanya kwasasazeka ebhodini, kwaye oku akuzange kuqondwe njengokukhanya kwe-LED, kodwa njengohlobo oluthile lomhlobiso amasebe omthi.
Ukukhokela: Eyona nto iphambili ye-icon ye-China yayikukwazi ukuyidibanisa ngokwasemzimbeni kwisikhululo sokubonwayo kunye nokubonisa iindlela zesebe kwindawo ye-3-D. Ubunokubona ngendlela yokomfuziselo indlela uluntu oluzicombulula ngayo iingxaki, indlela inkqubo yesisombululo imelwa ngayo lisebe lomthi, nendlela impumelelo ekhatshwa ngayo ilitha lokukhanya.
Inqaku lomguquli: Ividiyo yokuvavanya i-programmable China 1.0 Badge inokujongwa kwikhonkco .
Iibheji zethu sinokuzithatha njengesixhobo sobunjineli bezentlalo. Sisebenzisa ibheji ukudala ithuba lokuba udibane nabanye abantu kwaye usebenzisane omnye nomnye. Ikuntywilisela kuhlobo lokudlala indima, kwaye sichithe ixesha elininzi sicinga ukuba singayiphumeza njani le mbono ibe sisixhobo sokwenyani.
Ke, ndibuyele kwinkomfa yanamhlanje, eyeyona inkulu kwimbali yeDefCon. Sithathe ezininzi njengeehotele ezi-4, kwaye mhlawumbi asiyi kukwazi ukunika ingqwalasela elinganayo kubo bonke abathathi-nxaxheba, kodwa ukuba unayo nayiphi na ingxaki, nceda uqhagamshelane nathi, siya kukunceda uzisombulule. Ukuba ibheji yakho ineengxaki, sineworkshop apha enezixhobo eziyimfuneko. Kwaye ngoku ndinika umgangatho ku-Kingpin, oya kukuxelela malunga neebheji zalo nyaka.
UJoe Grand: Khange ndiyicinge into yokuba ndingaphinda ndibuyele apha ukuze sithethe ngeebheji. Ndayeka ukwenza iibheji kuba ndandiziva ngathi ndiyidlalile indima yam. Unyaka emva konyaka, kwakungathi ndikhuphisana nam, ndisenza into enye, ndisebenzisa nje iindlela ezintsha kunye nobuchwepheshe. Ngoko ndagqiba ekubeni ndinike indawo yam komnye umntu, vumela i-DefCon ikhule ngaphandle kwam kwaye umntu omtsha uya kuba nethuba lokuyila iibheji kuluntu lwethu. Kodwa ndandisoloko ndisithi ukuba i-DT inditsalele umnxeba, ndiya kubuya ndenze iibheji kwakhona.
Kuhle ukubona ukuba i-DefCon itshintshile njani, kumnandi ukubona abantu abaninzi abatsha, abohlukeneyo bekwazi ukugubungela iindawo ezininzi ezahlukeneyo zoluntu. Eneneni, ndazenza iibheji zam ndilindele imini endiya kuthi ekugqibeleni ndithethe ngayo ndize ndityhile zonke iimfihlo zam. Uyazi, kwezi nyanga zintandathu zidlulileyo bendicinga ngale nto kuphela, kwaye umfazi wam nabantwana bam abasakwazi ukuthetha nam ngalo mbandela.
Injongo ephambili yokudala ezi bheji kwakungekho ukwenzela ukuba babhenele kwii-techies kunye nabantu abaqonda izixhobo zombane. Bendifuna le icon ifikelele kubantu abaninzi kangangoko, kwaye akufuneki ube yihacker yehardware ukuze uyisebenzise. Bendifuna ukuba ifane nesikhokelo esiya kukuthatha ngeDefCon. Ngoko ke iinjongo eziphambili xa udala iibheji zaziza kunye nomdlalo oza kubandakanya amava e-DefCon yonke, ukusebenzisa iteknoloji eya kudibanisa uluntu lwethu lonke, kwaye yenze into eya kwanelisa wonke umntu kwi-DefCon.
Lo mdlalo, okanye imfuno ye-DefCon, inemithetho elula, eboniswe kwesi silayidi, apho wonke umntu obethe ibheji yakhe izolo waqala ukukhala xa eyibona.
Khange ndakhe naziphi na iipuzzle kwi icon. Iphazili kukufuna ibheji. Zininzi ii-icon zephazili phaya kwaye andikhange ndizame ukwenza into enje. Ndagqiba ekubeni ndenze umsebenzi omnye oqhelekileyo, ukukhangela isisombululo esiza kudibanisa abantu abaninzi, kwaye i-icon yayiza kusebenza njengesalathisi sokugqitywa kwalo mbuzo.
Nje ukuba uvule i icon yakho, iya kuqalisa ukudanyaza kancinci. Yile nto ndiyibiza ngokuba yimowudi yokutsala, imeko yokulungela ukusombulula iingxaki. Zininzi ii-icon ezibonisa iindawo ezahlukeneyo ekufuneka udlule kuzo ukuze ufikelele usukelo lwakho lokugqibela. Ndiyazi abantu abasele bezame ukubuyisela umva injineli ibheji, kodwa ayiloncedo kuba kukho iikowuti ezininzi oza kuzigqiba ngexesha lenkomfa, yindlela iibheji eziya kukunika ngayo amava eDefCon. Injongo yebheji ayikho ukwenzela ukuba ungadlula le misebenzi ngokuzama ukukrazula ibheji kwaye ufezekise ngokuzenzekelayo uloyiso, kodwa ukubethelela kuwe amava okusombulula kunye. Kwinkqubo yokutyhubela eli phulo udibana nabantu abatsha, ufunde izinto ezintsha, kwaye kuyonwabisa.
Isilayidi esilandelayo sibonisa ukuba "ukuzaliswa" komfanekiso kujongeka njani. Phezulu ekhohlo kukho i-eriyali, ezantsi kukho itshiphu ye-NFMI, ebonelela ngonxibelelwano olusekwe kwi-kufuphi-field magnetic induction, ngokuchaseneyo ne-RF yemveli. Siza kuthetha ngale nto ngokweenkcukacha kamva. Namhlanje ndiye ndaphawula ukuba abaninzi kwabo babekho babonakala βbephuzaβ iibheji zabo. Iibheji ziyafana nemagnethi, kuba umazibuthe unomhlaba wemagnethi, kwaye ibheji yethu iyayivelisa. Kodwa akukho mfuneko yokuba uzidibanise kunye umgama wonyawo olunye okanye ngaphezulu wanele ukuba iibheji zinxibelelane ngokukhululekileyo.
Nangona kunjalo, iibheji azishiyi utyikityo lwe-RF, ke umgeki ochwechwela iibheji ezisekwe kwirediyo ye-SDR akanakukwazi ukwenza nantoni na ngazo ngaphandle kokuba uzixhobise ngohlobo oluthile lwenzwa yemagnethi kwaye ungene phakathi kwam noJeff. Olu luluhlu olufutshane kakhulu, olukuvumela ukuba uququzelele "unxibelelwano olufihlakeleyo" ngaphandle kweDefCon, umzekelo, uhleli eklasini, ukurhweba ngamaphepha okukopela nomhlobo. Le nto inceda ukudibanisa nonke, ukwabelana ngolwazi, kodwa ungakuvumeli ukuba ukhuphe nayiphi na idatha, eya kuba buhlungu kakhulu kubaduni abaninzi.
Ibheji nayo iqulethe i-microcontroller, umqhubi we-LED kunye nesithethi se-piezoelectric. Ndizamile ukugcina uyilo lwehardware lulula, olungelula kwaphela, nangona lukhangeleka lulula kakhulu ngaphandle. Ndingathanda ukutsalela ingqalelo yakho kumathuba okunxiba le bheji. Kulula ukuthi, "masiyizame kwaye sibone ukuba kwenzeka ntoni," kodwa xa usenza into entsha, kuya kufuneka ucinge ukuba iya kusebenza njani kwaye ize nemeko yokusetyenziswa. Seza nendlela entsha yokuqinisa. Ngokwesiqhelo uthatha nje ibheji kwaye uyiklipule kwilanyard, kodwa iibheji zethu zokunyuswa zikuvumela ukuba uzityibilikise kwilanyard ukuze uqhoboshele ikharabhina, uyinxibe kwibhanti yesihlahla njengewotshi, okanye nakwibhanti yeenwele okanye entloko. Ukongeza, inokusetyenziswa njengeqhekeza lezacholo - i-brooch okanye i-amulet, ejinga entanyeni yakho. Saye sagqiba kwelokuba size nento entsha size sibone ukuba abantu baza kwenza ntoni ngayo. Le ipini zombini iqhekeza lobucwebe kunye nebheji.
Isilayidi esilandelayo sibonisa umzobo webhloko wesixhobo. Andifuni kungena kwiinkcukacha, ndikubonise nje izinto ezisisiseko zokusebenza.
I-PCB yomfanekiso igcina iprosesa ye-NXP ARM Cortex-M0. Le yinjongo yolawulo oluncinci, kodwa inamandla kwaye iyakwazi ukwenza imisebenzi esiyidingayo.
Ngendlela, unokujonga iinguqulelo zokuqala zolu yilo kunye neenkcukacha zoyilo lwe icon kwiseva yemidiya yeDefCon okanye kwiwebhusayithi yam.
Ibheji iqulethe umqhubi we-LED kunye nerediyo ye-NFMI, eyi-chip ye-NXP. Kwiminyaka embalwa edlulileyo kuye kwafuneka ndongeze esinye isibambi sebhetri kwibheji yam ngomzuzu wokugqibela kuba andizange ndiyiqonde imiyalelo, kunyaka ophelileyo ndasebenzisa iibhetri ze-CR123a kwiibheji zam, kwaye kule bheji ndaye ndagqiba ekubeni ndisebenzise isibambi seselfowuni encinane yemali. gcina isithuba 3 Q. Isilayidi esilandelayo sibonisa iinkcukacha zehardware yenkqubo.
Ilawula umqhubi we-LED, unxibelelwano lukanomathotholo, inkqubo yemibuzo kwaye imele izinto ezikhoyo kwisixhobo ngasinye sombane. Kukho i-NXP chip kwiqonga le-KL27, i-ARM-CORTEX MO + iprosesa kunye nento epholileyo njenge-NFMI. Le yinkqubo ye-magnetic induction esetyenzisiweyo ixesha elide, kodwa ngokwenene ifumaneka kuphela kwiimveliso ze-elektroniki eziphezulu. Kusenokwenzeka ukuba kukho iinkampani ezisisigidi ezingabaziyo nobuchwephesha obukhoyo. Ukuba uyi-hacker elula okanye injineli kwinkampani encinci, kuya kufuneka usebenze ukuyisebenzisa. Size nombono wokusebenzisa le teknoloji ngenxa yomsebenzi wam wangaphambili kunye nabafana baseFreescale, ndisenonxibelelwano lomnye waba bafana abasasebenzela i-NXP. Ndambiza kwaye ndachaza ukuba ndifuna ukwenza ibheji engaqhelekanga yeDefCon. Undicebise ukuba ndiqhagamshelane neengcali zeNFMI, eli liqela elincinci ngaphakathi kwe-NXP elinokundinceda.
Ndabathumelela i-imeyile ndibaxelela ngeDefCon kunye nendlela epholile ngayo ukuzisa iteknoloji entsha kuluntu lwethu, kwaye bavuma ukusebenzisana. Aba bafana bambalwa benkampani yaseBelgium iNFMI bandincedile ngokwenene. Kwitekhnoloji ye-NFMI, okuninzi kuxhomekeke ekubekweni kommkeli kunye nee-eriyali zothumelo, njengoko kubonisiwe kwisilayidi esisekunene. Ukuba i-receiver kunye ne-eriyali yokuhambisa i-perpendicular, isibonakaliso asiyi kufunyanwa. Le teknoloji inikeza ukuhanjiswa kwedatha okanye i-audio ngesantya esiphezulu kumgama ukuya kwi-1 m kwaye isetyenziswe, umzekelo, endaweni yeBluetooth kwi-headset. Isekelwe kwimveliso yentsimi yamagnetic, oko kukuthi, ngokwenene, sine-transformer ene-core air. Oku akwenzi indawo yerediyo eqhelekileyo phakathi kwezixhobo apho isiginali yakho inokuphazamisana nesixhobo somnye umntu, njengaxa usebenzisa iBluetooth.
Olu qhagamshelo lufana ne-air HiFi. Umthamo wejelo lonxibelelwano yi-596 kbit / s kwi-frequency carrier carrier ye-10,58 MHz. Olu qhagamshelo lukhawuleza ngakumbi kunokubonelela ngemodem yakho.
Ndachukunyiswa kukusetyenziswa kwe-NFMI ukusebenzisa i-microphones kunye nee-headphones kwii-headsets zomlilo kunye nezinye iinkonzo eziphuthumayo, ezisebenza kakhulu kunonxibelelwano lweBluetooth kwaye aluphazamisi ezinye izixhobo zerediyo. Into epholileyo kukuba le chip inokunceda ngokwenene ukunxibelelana koluntu lwe-DefCon, ukuyithatha kwinqanaba elitsha lobuchwepheshe.
Irediyo ye-NFMI eneneni iqulethe i-NFMI ngokwayo kunye ne-ARM chip, ngoko sine-2 microcontrollers ebhodini - enye yekhowudi yerediyo kunye neyomdlalo wekhowudi. I-NXP yanikezela injineli ukuba ibhale ikhowudi yale chip yerediyo eyenza unxibelelwano losasazo kuba kuya kuthatha ixesha elide ukuba ndibhale loo khowudi.
Okubangela umdla kukuba, kukho iinkampani ezininzi ezinobuchwepheshe obumangalisayo, kodwa amaxwebhu abo obugcisa akaxhomekekanga ekubhengezweni esidlangalaleni. Kodwa i-NXP yayinomdla kakhulu ekusebenzeni kunye ne-DefCon kangangokuba size nesisombululo sokungakhuphi naluphi na uxwebhu, ngoko ke ibheji yethu yomsakazo yibhokisi emnyama, siyisebenzisa nje ukuthumela idatha. Kukho ikhowudi ethile yesiko elayishwe kwi-chip yerediyo xa ibheji iqhagamshelwe kuthungelwano kwaye isebenzela uqwalaselo lwangaphambili. Uyabona ukuba ukukhanya kwe-LED ngokulandelelanayo kudlula kumanqanaba 3-2-1 - le yikhowudi elayishwayo ukusuka kwi-KL27, iipakethi ezininzi ezidluliselwe kwi-KL27, ezenza emva kokufunda.
Isilayidi esilandelayo sinikezela ngolwazi malunga nokubunjwa kwepakethi ye-8-byte, eya kuba nomdla kwabo bathanda ukukhwabanisa yonke into.
Andizithumeli ngamabom iipakethe zamazwe ahlukeneyo e icon, mhlawumbi ndiza kuthetha ngaloo Cawa ezayo, ngoko ngoku ndibonisa ipakethi ethunyelwe kwaye ifunyenwe yi-icon nganye kuluhlu kwikhonkco losasazo. Kukho i-icon yophawu olulodwa-inani elinamanani ali-9 okanye ali-10, andikhumbuli ncam, uhlobo lomfanekiso, iflegi yomqondiso womlingo, iiflegi zomdlalo kunye nebhayithi engasetyenziswanga. Ngoko ukuba uqhekeza le firmware, awuyi kukwazi ukudlulisela idatha yakho yebheji, kodwa uya kukwazi ukudlulisela enye idatha. Ukuba unenzwa echanekileyo, unokwenza enye into ngayo, njengokusebenzisana nayo yonke loo phakheji kwaye wenze umxholo wakho, kuba ikhowudi ilawulwa ekupheleni kwethu. Ungathumela nayiphi na idatha oyifunayo kwitshiphu yerediyo, kwaye iya kuhanjiswa ngokusasazwa kosasazo.
Enye inxalenye ebalulekileyo yebheji ngumqhubi we-LED onemodi yokulondoloza amandla ngokuzenzekelayo. Zonke ii-LED ziyakwazi ukujongana nomntu kwaye ziyahluka ukukhanya kwazo ngokuzimeleyo. Uninzi lwezi zixhobo zisebenza kwi-point-to-point okanye isiseko seselula, kodwa sisebenzisa ijenereyitha yexesha langaphambili apho i-icon nganye ihambisa kwaye i-icon nganye ifumana idatha kwaye emva koko ilale. Kule meko, imeko yokudluliselwa "enye kubo bonke" okanye "konke kuye enye" ββinokuvela. Asazi nokuba zingaphi iibheji ezinokuthi zinxibelelane ngaxeshanye, kodwa nangayiphi na imeko zingaphezulu kwamaqhekeza ali-10.
Enyanisweni, sifumana ingxoxo yeqela apho idatha itshintshiselwa khona. Ukuba ii-LED zebheji yakho ziqala ukuqhwanyaza, oko kuthetha ukuba kukunxibelelana nomntu. Ukuba ukwindawo efanelekileyo kwaye ngexesha elifanelekileyo, ixesha lokubona ibheji liya kuba malunga ne-5 ms, ngaphandle koko linokufikelela kwimizuzwana emi-5-10 ngokuxhomekeke kwinani leebheji "zokunxibelelana" ngaxeshanye - ngakumbi kukho, ngakumbi. ixesha elinokulithatha ukufikelela kwinqanaba lokugqibela lomdlalo. Kuyo nayiphi na imeko, incoko yeqela lentsebenziswano iyafuneka ukuze kugqitywe izicelo.
Lo mqhubi we-LED uxhasa iindidi ngeendidi zee-icon: kwizithethi, kubabonisi, kubo bonke abakhoyo, ngelixa igugu elikwi-icon likhazimla umbala ofanayo nee-LEDs. Isalathiso sokukhanya sivumela umenzi-ntetho ukuba abone abo bakhoyo kwinkomfa ngombala weebheji zabo, kodwa oku kwakungekho lula ukwenza.
