Cov neeg tua hluav taws tau hais tias siv ntoo Christmas ua tsev paj ntoo yog qhov tsis lees txais. Ntawm chav kawm, yog tias nws tau sib sau ua ke ntawm random, ces lawv yog txoj cai kiag li. Tab sis yog tias hom ntaub hnav khaub ncaws hauv tsev yog tsim raws li qee txoj cai, nws tseem yuav muaj kev nyab xeeb dua li chaw ua haujlwm.
Cov Lus Qhia
Kauj ruam 1
Siv lub xov tooj ntawm tes tsis tsim. Saib nws tsim li cas rau qhov siab thauj khoom tam sim no hauv milliamperes.
Kauj ruam 2
Siv lub super-ci LED ntawm ib qho xim thiab ib qho 200 ohm resistor uas muaj zog ntawm txog 0.5 W. Txuas lawv hauv series thiab txuas cov saw hlau no rau lub charger, saib xyuas cov polarity. Kev ntsuas nrog milliammeter (tseem suav nrog hauv Circuit Court hauv series) muaj pes tsawg milliamperes tus qauv siv no noj.
Kauj ruam 3
Faib cov thauj khoom ntau tshaj qhov tam sim no ntawm lub charger los ntawm kev kos tam sim no ntawm ib qho emitter. Koj yuav tau txais cov naj npawb ntawm cov emitters uas tuaj yeem txuas nrog nws. Txog kev cia siab, txo tus nqi no npaum li ntawm ib feem peb ntxiv.
Kauj ruam 4
Yog tias tsim nyog, txuas lub charger tso zis cable txuas ntxiv los ntawm qhov ntsaws ntawm phab ntsa rau tsob ntoo. Txig tag nrho cov kev sib txuas kom zoo zoo.
Kauj ruam 5
Cov sib txuas ntawm series-txuas nrog LEDs thiab resistors, tus naj npawb ntawm cov uas tsis ntau tshaj li qhov tau suav ib qho, txuas hauv kab sib txuas, soj ntsuam cov polarity, thiab txuas mus rau lub charger. Cov xov hlau uas koj txuas rau lawv yuav tsum tiv tag nrho kev siv tam sim no ntawm tag nrho cov paj ntaub ntev ntev.
Kauj ruam 6
Rov kho txhua qhov txuas kom zoo zoo kom tsis txhob muaj hluav taws xob luv (txawm hais tias feem ntau them cov hluav taws xob tiv thaiv luv luv tawm tsam, ib qho kev ntsuas ntxiv ntawm kev nyab xeeb yuav tsis nyob hauv txoj kev).
Kauj Ruam 7
Nthuav ntawm lub paj ntaub thiab nco ntsoov tias txhua yam ntawm LED taws teeb. Tam sim no koj tuaj yeem dai nws rau ntawm ntoo.
Kauj ruam 8
Nws yog qhov tsis tsim nyog siv kev ntsais teeb LED hauv ib qho garland es tsis txhob siv cov LEDs zoo. Txij li thaum tsis muaj cov tswj hwm, lawv yuav ntsais chaotically thiab dheev, uas tuaj yeem nrawm rau koj lub qhov muag. Tab sis diodes uas cia li ntseeg nkaws (tsis yog sai sai!) Kev hloov xim yuav ua.
Kauj Ruam 9
Yog tias koj xav tau, nteg tawm cov vaj huam sib luag zoo nkauj los ntawm cov LEDs, piv txwv li, zoo ib yam li pom ib qho hauv cov ncauj lus ntawm cov lus.
Kauj ruam 10
Tsis txhob, nyob rau hauv ib qho xwm txheej twg, siv koj lub tsev ua paj ntaub hauv tsev tawm sab nraud. Hloov lub charger nrog lwm tam sim ntawd yog tias koj pom cov khoom tawg ntawm nws rooj plaub. Tsis txhob siv cov charger nrog lub vov tshem tawm.
