DIYers … Peb txhua tus tau dhau los ntawm qhov xwm txheej thaum peb lub roj teeb siab kawg tsis khoom them cov roj teeb lithium polymer tab sis koj tseem yuav tsum tau them lub roj teeb 12v ua kua qaub thiab tsuas yog lub charger uas koj tau txais yog qhov muag tsis pom …. Yog qhov dig muag ib yam li nws tsis paub thaum nws tua lub roj teeb los ntawm kev them nws ntau…. Tib yam mus thaum tso lub roj teeb raws li koj tsis muaj lub tswv yim dab tsi them lub xeev nws yog.

Zoo kuv tau txais kev daws teeb meem rau qhov xwm txheej no raws li peb tab tom tsim lub roj teeb muaj peev xwm ntsuas qib los ntawm kev siv LM3914 IC thiab peb tseem yuav ntxiv qhov tseem ceeb rau peb cov khoom siv uas twb muaj lawm los txiav tawm kev them tam sim no thaum lub roj teeb puv them nyiaj

Yog tias koj tseem tab tom ntsib teeb meem tib yam ces qhov kev cuam tshuam no yog rau koj.

Kauj ruam 1: Tsim Schematic

Lub tswv yim yooj yim yog tsim cov roj teeb qhia qib tab sis tom qab dhau los ntawm cov ntaub ntawv kuv pom tias peb tuaj yeem tswj tau qhov teeb meem them nyiaj ntau dua los ntawm kev ntxiv cov xa tawm uas hloov qhov kev xa khoom mus rau lub charger thaum lub roj teeb ntaus qib siab tshaj.

Txawm hais tias nws tsis yog qhov kev tswj hwm kev them nqi tab sis nws zoo dua los txiav tawm lub tsub them tam sim no ua ntej peb dhia saum qhov siab tshaj qhov txwv tau teev tseg ntawm lub roj teeb uas yog 14.4v.

Txij li thaum peb yuav siv 10 LEDs los qhia txog qib roj teeb yog li txhua LED sawv cev kwv yees li 10% them.

Ntxiv mus tam sim no los ntawm LEDs raug txwv siv tus tiv thaiv hla tus pin 7 ntawm LM3914 IC yog li peb tsis tas yuav siv tus neeg tiv thaiv tus kheej rau txhua tus ntawm lawv.

Dhau li ntawd qhov sib txawv resistors R3 thiab R4 tau siv los teeb tsa theem qis thiab qis dua rau cov roj teeb uas koj yuav siv. Rau cov roj teeb kua qaub nws feem ntau yog 10.8v tso tawm tag nrho thiab 14.4v them tag nrho. Ntxiv rau qhov ntawd tom qab.

Tus so koj pom yog pawg ntawm cov khoom pub dawb raws li qhia hauv cov ntaub ntawv.

Kuv kuj tau ntxiv Gerber cov ntaub ntawv rau PCB hauv qib no yog li nco ntsoov xyuas nws.

Kauj Ruam 2: Tsim PCB (Luam Circuit Board)

Zoo kuv nyiam nws thaum kuv ua kom zoo thiab yog ib yam uas kuv ib txwm nyiam. Yog li es tsis txhob cuam tshuam txhua yam ntawm daim duab qhia chaw kuv tau txiav txim siab los ua qhov Circuit no hla PCB, yog li kuv tsim ib qho. Zoo cov kauj ruam no tsis tas yuav tsum tab sis cov kev siv zog ntxiv no yuav tau them tom qab thiab kuv yuav tsum hais tias koj yuav tsum tau sim nws.

Raws li cov txheej txheem tau ua tiav Kuv tau mus rau PCBWAY, txheeb xyuas txhua qhov kev xaiv uas kuv xav tau thiab rub tawm cov ntaub ntawv gerber. Qhov zoo tshaj plaws txog lawv cov kev pabcuam yog tias lawv tshuaj xyuas koj cov qauv hauv ib teev thiab qhia rau koj paub yog tias muaj teeb meem nrog nws.

Peb tau txais PCBs hauv ib lub lis piam thiab qhov ua tau zoo tham ntau ntawm nws tus kheej yog li cov txiv neej tau saib lawv lub vev xaib raws li lawv ua txoj haujlwm no tau los ntawm kev txhawb nqa nws.

Kauj Ruam 3: Cov Cuab Yeej thiab Cov Khoom

Tom qab tau txais PCBs, peb tau txiav txim siab los sau cov cuab yeej thiab cov khoom siv uas tau siv hauv txoj haujlwm no.

Cov npe ntawm cov cuab yeej siv:

• Soldering Hlau
• Soldering Hlau
• Ntau 'meter'
• Pliers

Cheebtsam uas tau siv hauv txoj haujlwm no tau teev tseg hauv BOM (Bill Of Material).

Kauj Ruam 4: Sib dhos PCB

Tom qab ntawd peb tau ntsaws cov hlau txuas, rub tag nrho cov khoom thiab pib siv lawv. Kuv yuav muab cov kev txuas mus rau schematic, cov ntaub ntawv gerber thiab cov npe ntawm cov khoom siv hauv cov lus piav qhia hauv qab no. Tam sim no txhua lub Cheebtsam tau tso rau hauv qhov chaw raws li qhia hauv PCB thiab qhov ntawd yog qhov zoo ntawm kev teem sijhawm tsim cov PCB ua ntej.

Tam sim no ib zaug txhua yam tau muab tso rau hauv qhov chaw peb nyuam qhuav tso lub paj hlwb ntawm txoj haujlwm no uas yog LM3914 IC. Nco ntsoov tso IC nrog qhov thais kom raug raws li qhia. Kuv ib txwm nyiam siv IC holeder uas los tau yooj yim yog tias koj hlawv IC koj tuaj yeem hloov tau yooj yim.

Kauj Ruam 5: Qhov Kawg

Lub Circuit Court txuas nrog lub roj teeb thiab ntsuas raws li qhov txwv qis thiab qis dua qhov tau hais tseg ntawm lub roj teeb.

Qhov no tuaj yeem ua tiav siv ob qhov sib txawv resistors raws li peb tau tham txog ua ntej. Thaum peb txuas lub nra hla lub roj teeb peb tuaj yeem saib xyuas tus nqi them thiab nyab xeeb tshem tawm qhov thauj khoom thaum lub roj teeb zoo li tsis muaj nqi.

Tom qab ntawd cov khoom siv ntawm lub roj teeb them nyiaj tau txuas nrog hla kev xa tawm. Raws li lub roj teeb nce mus txog nws qhov siab tshaj plaws cov khoom siv ntawm lub charger tau txiav tawm thiab yog li ntxiv tus nqi tswj hwm rau peb li hu ua dig muag charger.
