Zoo siab txais tos txhua tus:-) Nov yog kuv thawj cov lus qhia yog li ntawd cov lus pom zoo txais tos:-) Qhov kuv cia siab tias yuav qhia koj yog yuav ua li cas kom pom teeb pom kev nrawm LED uas nyob ntawm TINY kab kab. Dab tsi koj xav tau: CableLEDsResistors (510Ohms rau 12V) StapelsSoldering hlauCutters thiab Lwm yam hauv paus Hammer thiab tus ntsia hlau! (CEEB TOOM rau n00bs) LEDs xav tau kwv yees li 30 milli amps (0.03 Amps) lossis lawv hlawv tawm Txhawm rau ua haujlwm tawm koj qhov kev cia siab siv: V = IRVoltage (V) = 12Amperage (I) = 0.03 (30*10)-3)Resitance (R) =? SO: V/I = R12/0.03 = 400Ohmsor ntau… kuv siv 510 yog li kuv cov LEDs tsis ua haujlwm zoo tshaj qhov lawv tuaj yeem ua
Kauj Ruam 1: Cov Nqi
Cov Nqi: Cable: 8.51GBP qib siab dawb cable rau 50m ($ 13.99) LEDs: 6.18GBP (Tus nqi pheej yig dua 1000) (cov LEDs kuv siv yog 13, 000 thiab 6, 000 mcd nrog tus tim tswv ntawm 25 degrees) Resistors x100: rau 0.99GBPStaples: Zoo pheej yig … Uas ua haujlwm tawm ntawm: 0.89 ib lub 'meter' Kev sib nrug ntawm 1 LED rau 10cm yog txaus (tau txais qhov sib nrug los yog nws zoo li coj txawv txawv) uas tsis phem rau qhov zoo nkauj tiag tiag uas qhov nruab nrab lub teeb yuav nyob 11+ Xyoo ! Kuv tau siv lub zog hloov pauv uas kuv tau dag txog tab sis txhua yam uas yog 12V thiab dag txog yuav ua qhov zoo:-) Ib yam li txoj cai dav dav koj xav tau 30mA ib LED. (qhov no tsis yog qhov tseeb tiag, tab sis nws yuav ua rau koj nyob hauv cov ntsiab lus) yog li yog tias koj muaj 20 leds koj xav tau (30*10-3)*20 = 600mA lossis 0.6 A
Kauj Ruam 2: Txuas Kab Hauv Chav
Yooj yim thiab yooj yim koj yuav tsum tau siv 2 lub xov tooj thiab xyuas kom koj tsis txhob hla lawv hla ntawm txhua lub ntsiab lus lossis nws yuav ntxhov
Pom hauv daim duab yog qhov koj txuas yuav tsum zoo li txhua txoj hauv kev ib ncig ntawm chav (lossis qhov twg koj xav tau cov LEDs)
Kauj Ruam 3: Ua cov LEDs
Tam sim no qhov kuv nyiam txog cov kab ke no yog tias koj tuaj yeem hloov pauv, txav thiab hloov xim kom yooj yim!
Yuav npaj cov LEDs li cas … Khoov ib ces kaum ntawm tus neeg tso npe thiab + (zoo) ceg ntawm LED thiab nqes lawv ua ke. Tom qab ntawd muab tso rau ntawm lub lauj kaub. Tom qab ntawd txiav qhov ntxiv. Thiab leej twg hais tias soldering nyuaj! Tom qab ntawd khoov ob txhais ceg zoo li qhia hauv daim duab kom ob txhais ceg taw mus rau hauv qab thiab ua rau lawv zoo ib yam ntev. txog 4mm tsis ntev ok tam sim no ua ntau npaum li koj xav tau … Nws yooj yim …
Kauj ruam 4:
Muab tag nrho ua ke!
Ok yog li LEDs tsuas ua haujlwm ib txoj kev ib puag ncig kom paub tseeb tias txhua lub LEDs + (zoo) ob txhais ceg (qhov kawg nrog tus tiv thaiv) mus rau hauv tib lub cable. Siv tus ntsia hlau thiab txhawm rau txhawm rau txhawm rau txhawm rau kom koj tuaj yeem lo ob txhais ceg ntawm LED rau hauv kab ntawv Tam sim no ua tib yam txhua 10cm …
Kauj ruam 5: Hwj chim rau
QHOV TSEEB!
Txaus siab thiab ua tsaug rau kev nyeem ntawv. Kev hloov kho yav tom ntej: Siv cov khoom siv hluav taws xob kom ci ntsa iab raws li lub zog tau qhib (teeb pom kev zoo me me) thiab lub suab txav txav kom zoo li kuv tuaj ntawm lub qhov rooj lub teeb tuaj. Ua tsaug rau txhua tus nyeem:-) yog tias koj xav tau ib feem twg (qhia hauv cov lus qhia kuv tuaj yeem muag lawv rau koj) thiab ib qho nyiaj pub dawb (raws li kuv yog cov tub ntxhais kawm txom nyem) tau txaus siab heev!

Txuag lub Ntiaj Teb thiab Koj Lub Hnab. $$ Hloov Koj P & S Pheej Yig Pheej Yig Lub Koob Yees Duab kom rov them rov qab: 4 Cov Kauj Ruam (nrog Duab)
Txuag lub Ntiaj Teb thiab Koj Lub Hnab. $$ Hloov Koj Li P & S Pheej Yig Tshaj Lub Koob Yees Duab kom rov tau txais txiaj ntsig: Ntau xyoo dhau los, Kuv yuav Dolphin Jazz 2.0 Megapixel Digital Camera Nws muaj cov yam ntxwv zoo thiab tus nqi. Nws kuj tseem muaj qhov qab los noj mov rau AAA Bateries. Tsis yog ib tus neeg taug kev deb ntawm qhov kev sib tw, kuv xav tias kuv yuav hloov kho nws kom siv lub roj teeb rov tau los kom tsis txhob nkim sijhawm ntxiv
