Nyuam qhuav pib lub xyoo no kuv pom tawm txog lub moos me me no. Nws tsuas yog $ 10, uas ntau dua li peb feem ntau siv rau kas fes lossis daim pib ua yeeb yaj kiab yog li kuv zoo nkauj tias leej twg tuaj yeem them taus. Zaub tau yooj yim nyeem (qhov tseeb tiag, zoo dua qee tus qauv kim dua) tab sis tsuav yog muaj lub teeb. Sai li nws tau tsaus ntuj thiab koj xav pom lub sijhawm nws yog dab tsi, koj yuav poob siab. Nrog nws lub teeb ntsuab ntsuab, koj yuav tsis tshua pom feeb thiab vib nas this. Yog li, tsis txhob tshawb nrhiav lwm txoj hauv kev, kuv tau ua qhov kev hloov pauv yooj yim no kom nws nyeem tau ntau dua (thiab rau cov uas xav tau lwm txoj kev, txheeb xyuas Casio A168). Qhov qauv no yuav tsis cuam tshuam rau dej tsis kam (F91W tsuas yog WR - Dej Tiv Thaiv tab sis Kuv tau pom qee tus neeg ua luam dej thiab dhia dej nrog nws) thiab nws yuav tsis cuam tshuam rau lub roj teeb lub neej (txiav txim siab tias kuv tsis hloov nws 100 ohm resistor). Kuv tab tom siv modded saib txog 5 lub hlis tam sim no thiab kuv tsis muaj teeb meem ib leeg, kuv txawm siv da dej nrog nws.

Txij li kuv lub ntsiab lus tsis yog lus Askiv thiab kuv tseem yuav tsum txhim kho ob peb yam (thiab thaij duab ntau ntxiv rau lub sijhawm tom ntej kuv tshem tawm cov saib) Kuv pom zoo nyeem qhov no ua ntej. Nws qhia txog kev sib cais nrog ntau yam ntxiv. Kuv tseem yuav sim suav nrog ntau cov yeeb yaj kiab thiab cov lus qhia rau cov neeg uas tsis muaj kev paub nrog hluav taws xob/khoom siv hluav taws xob.

Khoom siv

- Casio F91W (Yuav tsum ua haujlwm ntawm lwm tus qauv nrog "Illuminator" hom teeb pom kev zoo, tab sis lwm tus yuav twb muaj 2 LEDs, zoo li AE1200 piv txwv)

-Tweezers

Ntsia Hlau

-Soldering hlau, solder thiab flux

-Small gauge insulated wire (koj tuaj yeem pom nws ntawm el. Lub cev muaj zog, tus hais lus thiab lwm yam) - tsis yog tooj liab hlau yuav tsis ua haujlwm, koj yuav luv thiab ua rau koj lub xov tooj puas

-0603 lossis 0805 SMD LED (qee yam ze rau nws, yog tias nws loj dhau nws yuav tsis haum)

- Kua nplaum (yeem)

- Daim kab xev hluav taws xob

Kauj Ruam 1: Lub Sijhawm Disassembly

Qhov no yuav tsum yooj yim rau txhua tus, koj tsis tas yuav tshem lub pluaj. Koj tsuas yog tig koj lub ntsej muag saib (muab qee daim ntawv mos los yog ntaub so ntswg tso rau hauv qab kom tiv thaiv khawb) thiab tshem tawm 4 tus ntsia hlau uas tuav lub nraub qaum.

Thaum koj ua qhov ntawd, tshem daim ntawv rov qab thiab daim ntawv me uas nyob tom qab ntawm tus qauv. Koj tseem tuaj yeem tshem cov roj hmab ntsaws ruaj ruaj (thiab hloov lawv tom qab yog tias koj lub moos qub). Txhua tus qauv tawm ua tib zoo.

Cov vis dis aus no yuav tsum pab koj yog tias kuv cov lus qhia tsis txaus raws li nws qhia yuav ua li cas hloov thawj LED (qhov kev hloov kho no zoo ib yam, tab sis kuv nyuam qhuav ntxiv lwm lub LED ua ke)

Kauj Ruam 2: Module & Soldering Tshiab LEDs

Thaum koj tau txais cov qauv tawm, coj tus tweezer lossis lub taub hau me me ntswj ntsia hlau thiab ntswj tawm lub yas roj teeb tuav. Roj teeb yuav tsum poob los ntawm nws tus kheej, nco ntsoov polarity yog li koj tuaj yeem tso nws rov qab tom qab (tsis zoo (-) tab tom ntsib PCB, qhov zoo (+) yuav tsum tau ntsib lub ntsej muag hlau).

Thaum koj tau ua txhua yam, koj tuaj yeem rub PCB (Luam Circuit Board) thiab tig nws ib ncig. Koj yuav tsum pom cov coj me me ntawm ib sab ntawm lub rooj tsavxwm (kuv tau txais daim duab los ntawm bobyong808, kuv vam tias yog lawm, yog tsis yog, xa xov rau kuv yog li kuv tuaj yeem ua tau tshem nws). Desolder nws, peb yuav tsis xav tau qhov no ntxiv lawm (koj tuaj yeem ua rau nws puas tsuaj, tsuas yog ceev faj kom tsis txhob puas PCB). Chaw nres tsheb cua kub yuav zoo, tab sis qhov no yog qhov yooj yim rau desolder nrog tus qauv tooj liab. Kev pab txhais tes kuj tseem muaj txiaj ntsig vim tias SMD LEDs me me tiag, tej zaum txawm tias tau txais lub iav tsom iav.

Kuv pom zoo saib cov vis dis aus los ntawm GreatScott txog kev siv cov khoom siv SMD zoo, qhov no yuav pab koj yog tias koj tsis tau muaj kev paub nrog SMD soldering.

Thaum koj tshem nws tawm, muab koj lub LED tshiab tso rau hauv qhov chaw (qhov zoo ntawm LED yuav tsum mus rau kev sib cuag/khawm, tsis zoo rau tus tiv thaiv). Cov tshuaj txhuam zoo thiab cov dej ntws pab tau tiag tiag thaum siv cov khoom siv SMD. Siv daim duab los siv rau qhov uas LEDs sab zoo yuav tsum yog. Tau txais lwm lub LED thiab cov kab me me ntsuas qhov ntsuas hluav taws xob rau nws, qhov no yuav tsis yooj yim yog li siv koj lub sijhawm. Tshem tawm cov rwb thaiv tsev los ntawm xaim ua ntej los ntawm khawb lossis txhuam ob peb millimeters ntawm qhov kawg. Kuv pom cov vis dis aus hais txog qhov no, nws tuaj yeem pab koj nrog nws. Thaum koj ua tiav, muab nws sib dhos rau thawj LED (txuas ob qhov zoo ua ke, txuas ob qho tsis zoo ua ke). Muab daim kab xev hluav taws xob me me tso rau hauv LED yog li nws yuav tsis luv dab tsi, koj tseem tuaj yeem muab cov kua nplaum tso rau hauv qhov chaw, tab sis qhov no yog nyob ntawm yeem vim tias kuv tsis tau lo rau kuv thiab nws tsis txav mus los.

Kuv tau txais kuv cov LEDs los ntawm Nokia 5110 zaub yog li yog tias koj muaj pawg loj ntawm cov khoom siv hluav taws xob qub, koj tuaj yeem tshawb nrhiav cov xov tooj qub lossis cov khoom siv hluav taws xob uas muaj SMD LEDs, tab sis yog tias tsis yog, lawv pheej yig heev (koj tuaj yeem pom 100pcs rau duas lossis ob ntawm ebay)).

Kauj ruam 3: Sib dhos

Tam sim no muab txhua yam rov qab los ua ke, thib ob LED yuav tsum haum rau hauv qab yas dawb, yuav tsum muaj chaw nyob ntawm sab xis kom dav txaus kom haum rau LED. Muab roj teeb rov qab rau hauv (qhov tsis zoo (-) tab tom ntsib PCB, qhov zoo (+) yuav tsum tau ntsib tus tuav hlau). Thaum cov hlau tuav hauv qhov chaw, koj lub moos yuav tsum ua haujlwm (thiab pib txij 12:00:00), yog tias tsis yog, txheeb xyuas yog tias koj tso roj teeb kom raug thiab yog tias koj tsis hnov qab cov roj hmab sib txuas ntawm cov zaub. Yog tias lawv tau qias neeg lawv yuav tau txais kev sib txuas tsis zoo thiab tso saib tsis tau lossis tsis pom dab tsi hlo li. Ntsuam xyuas seb lub teeb pom kev zoo ua haujlwm, yog tias nws tsis yog koj yuav tau tig lub teeb pom kev zoo los yog koj yuav tau hlawv lawv yam tsis raug.

Ceev faj kom tsis txhob thim rov qab vim tias lub me me piezo hluav taws xob hais lus nyob tom qab ntawm nws uas ua suab thaum koj nyem thiab tswb. Yuav tsum muaj cov hlau me me uas tau tiv nrog lub phaj rov qab, kho nws nrog tus hais lus. Kuv tseem tso kuv lub F91W rau ntawm lub pluaj nato, nws zoo kawg li lub teeb no saib zoo li cas. Yog li xis uas koj yuav hnov qab tias koj hnav nws.

Nov yog nws, yog tias koj tau ua nws, nrog koj zoo siab.
