Hauv Cov Lus Qhia Kuv yuav qhia koj yuav ua li cas thiaj teeb lub teeb tawm ntawm qhov qub, 35mm, zaj duab xis canister thiab qee qhov ci ntsa iab LEDs!

Koj tsis tas yuav siv 10 $ ntawm lub teeb nyem uas tsis yog qhov kaj. Rau 4 $ lossis tsawg dua, nyob ntawm yam koj tau dag nyob ib puag ncig lub tsev, koj tuaj yeem ua lub teeb ci LED tiag tiag. Nws tau txais kev mus pw hav zoov lossis tsuas yog rau kev lom zem tom vaj. Lub teeb nyem no yooj yim ua, zoo li txias thiab tseem ceeb tshaj, ua tau zoo!

Kauj Ruam 1: Cheeb Tsam

Txiav tawm 8 daim hlau (zoo li hauv daim duab 1) thiab hle lub rwb thaiv tsev ntawm qhov kawg.

Cov LEDs tau txuas nrog ua ke, uas txhais tau tias txhua qhov tsis zoo (luv dua) ob sab tau txuas ua ke thiab txhua qhov zoo (ntev dua) sab tau txuas ua ke. Nqa cov xaim thiab muab nws tso rau ntawm LEDs. Ib qho los ntawm ib qho txuas ob sab ib sab (ntev dua ntev dua luv dua luv dua) cov xov hlau thiab txuas lawv. (Daim duab 2, 3, 4 thiab 5) Tsis txhob txiav txhua qhov kawg ntawm LEDs, tawm ob, ib qho zoo (ntev) thiab ib qho tsis zoo (luv) (duab 6) Kuaj nws. Nqa lub roj teeb 3V npib ntawm lub xov tooj thiab muab nws tso rau ntawm qhov ua kom raug. Yog tias txhua yam ua tau zoo txog tam sim no LEDs yuav tsum sau tawm. (Daim duab 7 thiab 8) Ntawm ib qho txhuas ntawm cov kab laug sab LED ntev dua xaim. Sawb me ntsis ntxiv ntawm cov rwb thaiv tsev ntawm sab oposite thiab khoov ti. (duab 9 thiab 10)

Kauj ruam 5: Hloov

Coj tus tes hloov thiab txiav ob daim hlau ntev dua. (Daim duab 1)

Tshem tawm cov rwb thaiv tsev ntawm qhov kawg. Qhov kawg ntawm ib txoj kab xaim me ntsis ntxiv ntawm cov rwb thaiv tsev thiab khoov cov xaim tsis-insulated. (daim duab 2) Muab cov hlau xaim los ntawm qhov hloov mus rau cov hlau lead uas seem. (daim duab 4 thiab 5)

Kauj Ruam 6: Roj teeb

Ob qhov kawg ntawm cov xaim uas peb khoov (daim duab 1) txuas rau lub roj teeb.

Txuas lawv mus rau lub roj teeb dawb daim kab xev hluav taws xob (daim duab 2) thiab koj lub Circuit Court tau ua tiav! (Daim duab 3) Kuaj nws los ntawm kev thawb lub hloov, yog tias txhua yam zoo LEDs yuav tsum tau sau.

Kauj Ruam 7: Ua Lub Qhov rau Hloov

Ntawm zaj duab xis canister ua lub qhov rau qhov hloov. Koj tuaj yeem siv lub laum lossis txhua yam uas tuaj yeem ua rau tag nrho.

Kauj Ruam 8: Tso Txhua Yam Ntxiv

Muab Nws Txhua Yam Ntxiv
Muab Nws Txhua Yam Ntxiv

Tam sim no muab nws tag nrho ua ke. Muab qhov hloov pauv hla lub qhov, muab lub roj teeb tso rau hauv lub canister thiab kaw tag nrho.

Kauj ruam 9: Ua tiav

Ua tiav!
Ua tiav!

Koj ua tiav !!!

Koj tau tsim koj tus kheej ultra ci LED zaj duab xis canister flash teeb !!! Ua tsaug rau kev nyeem ntawv, tso lus tawm thiab tsis txhob hnov qab ntsuas!
