Yog tias koj muaj, txiav ib daim duab me me ntawm Kapton daim kab xev thiab lo rau sab hauv qab kom npog hauv qab tab. Txwv tsis pub, tsuas yog siv qee daim kab xev ua kom tiav. Qhov no yog qhov uas cov txheej txheem pab tau tiag tiag - ua raws nws ua tib zoo thiab koj yuav tsum ua li cas. Position lub rooj tsavxwm nyob tom qab ntawm daim ntawv loj loj thiab txiav txim siab tias koj yuav khiav cov xov hlau los ntawm LEDs thiab hluav taws xob li cas. Thaum koj txaus siab, txiav cov xov hlau uas yuav ncav cuag los ntawm pawg thawj coj mus rau cov hluav taws xob thiab txuas ib qho kawg mus rau ntawm lub rooj tsavxwm. Tom qab ntawd txiav thiab muab cov kab xaim txuas mus rau LEDs. Koj kawg, txiav ib khub ntawm cov xov hlau thiab txuas lawv nruab nrab ntawm pawg thawj coj saib thiab lub hwj chim txuas. Rwb thaiv lub hwj huam hluav taws xob nrog cua sov-ntsws lossis hluav taws xob daim kab xev.

Ib txwm peb yuav xav kom nyab xeeb teeb tsa cov khoom siv hluav taws xob nyob tom qab ntawm daim ntawv loj loj. Kuv siv ob daim kab xev coj los siv ob daim kab xev thiab tshem tawm ib nrab nti ntawm rwb thaiv tsev tawm ntawm qhov kawg. Hmoov tsis zoo koj tsis tuaj yeem muab lawv txuas rau ntawm daim kab xev aluminium electrodes, yog li peb yuav kaw lawv rau qhov ntawd. Tshem cov hlua thiab ntxuam lawv tawm, tom qab ntawd kaw lawv rau hauv nruab nrab ntawm cov hluav taws xob. Aluminium daim kab xev ua rau lo zoo dua - tsuas yog ua kom nws tsis luv luv ntawm cov hluav taws xob! Ib txoj hauv kev zoo dua, yog tias koj muaj nws, yog siv cov tshuaj epoxy los ua kom cov hlau xaim.

Ua ntej ntsaws ib yam dab tsi rau hauv, ua ib qho ntxiv tshuaj xyuas nrog lub multimeter los saib rau luv Circuit Court thiab kev sib txuas kom raug. Siv cov txheej txheem los ua phau ntawv qhia, ntsuas ntawm ntau cov ntsiab lus raws li koj tuaj yeem ua kom ntseeg tau tias txhua yam tau txuas nrog kom raug. Xyuas kom tseeb tias cov xov hluav taws xob ntsuas hluav taws xob tsis luv rau ib yam dab tsi. Qhov tseem ceeb tshaj, ua kom ntseeg tau tias tsis muaj luv luv los ntawm lub zog rau hauv av, ntawm ob txoj kab +12V thiab +5V Tam sim no, ntsaws nws thiab pom dab tsi tshwm sim. Ua kom npaj txhij yank tawm txoj hlua yuav tsum muaj dab tsi pib haus luam yeeb (tab sis tsis muaj dab tsi yuav tsum, yog tias koj cov xov hlau raug lawm). Mus tom ntej thiab sim nws - kov lub ntsuas cua thiab pom tias LEDs qhib. Kuv muaj qee cov xov hlau nyob hauv qhov chaw tsis raug (kev phom sij ntawm kev ua haujlwm txog 2 teev sawv ntxov!). Tom qab ntawd kuv pom ib lub capacitor busted. Thaum kawg, Kuv pom tau tias lub inverter tau qhib-ntws, yog li nws xav tau rub tawm tus tiv thaiv ntawm nws cov zis. Yog tias koj li tsis ua haujlwm, koj yuav tsum muaj peev xwm txheeb xyuas cov teeb meem feem ntau nrog lub multimeter. Cias sim ntsuas qhov ntsuas hluav taws xob ntawm txhua kis hauv Circuit Court, thiab saib rau qhov ntsuas hluav taws xob uas tsis yog qhov lawv yuav tsum yog. Yog tias koj tsim txoj haujlwm no, Kuv kuj zoo siab los pab daws teeb meem!

Yog li !! Txhua yam ua haujlwm? Zoo kawg! Qhov kawg ua yog npog lub nraub qaum nrog qee yam uas yuav tiv thaiv cov khoom siv hluav taws xob. Kuv siv lub xwmfab ntawm cov paj ntaub daj, tab sis koj tuaj yeem siv txhua yam uas qiv kev tiv thaiv rau pawg thawj coj hauv qab, thiab tseem tsis ua haujlwm. Qhov no yog ib qho tseem ceeb heev, txij li ib qho khoom siv uas tuaj ze ntawm lub ntsuas cua yuav qhib rau lawv.
