Kev tswj cov chaw taws teeb yog neeg xiam rau ntau yam: kev sib chwv ntawm kev sib cuag, kev puas tsuaj rau tus resonator, LED. Kev ua tiav zoo ntawm kev tswj kav yog tsuas yog ua tau yog tias thaj chaw ntawm qhov tsis ua haujlwm tau txiav txim siab raug.
Cov Lus Qhia
Kauj ruam 1
Nqa lub xov tooj ntawm tes nrog lub koob yees duab ua haujlwm. Tig lub hom tsim nyog nyob rau hauv nws, thiab tom qab ntawd ncaj qha cov chaw taws teeb tswj hwm LED mus rau lub koob yees duab lens. Nias txhua tus yuam sij ntawm nws lem.
Kauj ruam 2
Lub flashes ntawm infrared LED ntawm cov chaw taws teeb tswj tsis tau pom tau los ntawm tib neeg lub qhov muag, tab sis pom los ntawm lub xov tooj koob yees duab. Yog tias nws hloov tawm tias lub LED xaim thaum koj nias qee tus yuam sij, tab sis tsis teb rau lwm tus nias, saib rau qhov tsis zoo ntawm cov keyboard. Chaotic qeeb hloov mus rau hauv thiab tawm ntawm lub diode tsis hnov mob rau nias txhua tus yuam sij qhia tias tsis ua hauj lwm ntawm lub resonator. Thaum kawg, qhov ua tiav ntawm luminescence yuav yog vim muaj kev ua tsis zoo ntawm ob lub resonator thiab lub roj teeb lossis LED.
Kauj ruam 3
Hauv rooj plaub tom kawg, ua ntej qhib thiab kho cov chaw taws teeb, hloov cov roj teeb hauv nws, soj ntsuam cov polarity thiab rov tshawb xyuas lub cuab yeej. Nws yuav tsis tas yuav tsum tau kho tom qab ntawd. Yog tias nws hloov tawm tias qhov laj thawj tsis nyob hauv roj teeb, tshem lawv thiab ces disassemble cov chaw taws teeb tswj hwm. Yog tias cov keyboard ua tsis zoo, ntxuav nws los ntawm kev tso txhua feem ntawm lub cuab yeej, tshwj tsis yog lub roj teeb, hauv lub tais ntim dej nrog me ntsis ntxuav tais diav ntxiv. Tom qab cia lawv nyob ntawd li ob teev, tshem tawm thiab qhuav ntawm chav tsev li ob peb teev ntxiv. Tsis txhob sim kom ceev cov txheej txheem nrog lub tshuab ziab plaub hau - qhov no yuav ua rau lub rooj tsavxwm mus ua kom sov thiab thaum kawg ua tiav.
Kauj ruam 4
Rov ntsuas cov chaw taws teeb, ntxig lub roj teeb thiab kos. Yog tias tom qab ntawd tsis yog txhua tus yuam sij ua haujlwm, qhov laj thawj yog qhov depletion ntawm kev ua cov txheej txheem ntawm qhov sib chwv ntawm cov hnab looj roj hmab. Rov muab kho nws yog qhov teeb meem.
Kauj ruam 5
Yog hais tias cov LED lossis resonator yog faulty, cam nws tawm. Thov nco ntsoov tias cov LED yog lub caij ncov qaumteb qabteb, yog li ua ntej soldering, kos duab seb tus pin twg tau soldered qhov twg. Kuj tseem nco ntsoov tias cov resonators yog qhov xav tsis thoob thiab yog li tsis ntau ntau dua li cov LEDs. Nqa qhov tsis xws luag nrog koj mus rau lub khw muag khoom hluav taws xob, qhov uas koj qhia nws rau tus muag - nws yuav xaiv lwm qhov uas phim qhov tsis haum. Nco ntsoov hais tias koj xav tau qhov hluav taws xob infrared LED, thiab lub tshuab ntsuas hluav taws xob thaum lub caij nyoog tib yam li cov qauv.
Kauj Ruam 6
Tom qab soldering ib qho tshiab diode lossis resonator, sib sau cov chaw taws teeb tswj thiab tshawb xyuas nws dua siv xov tooj. Tom qab ntawd sim nws tawm nrog koj lub TV. Nws tsis tshua muaj tshwm sim hais tias cov chaw taws teeb tswj uas flawlessly ua kom muaj infrared flashes thaum koj nias tus yuam sij tsis ua haujlwm nrog lub TV. Qhov no txhais tau tias tom kawg muaj qhov yuam kev photodetector lossis av tau sau nruab nrab ntawm nws thiab lub qhov rais hauv pem hauv ntej vaj huam sib luag. Lub TV tsuas yog ntxuav thiab kho cov los ntawm cov neeg tsim nyog vim nws muaj qhov ntsuas hluav taws xob ntau.
