Nyob zoo txhua tus, txoj haujlwm no yog kuv thawj Kev Qhia Ntawv yog li kuv yuav sim ua qhov zoo tshaj plaws.

Hauv txoj haujlwm no, kuv yuav piav qhia koj li cas kuv thiaj tswj tau los tsim cov saw caj dab PCB no uas ci hauv qhov tsaus ntuj! Yuav kom ncaj ncees, qhov no yog qhov haujlwm zoo tshaj yog tias koj xav kawm paub txog txheej txheem teeb tsa hluav taws xob sib dhos.

Ua ntej tshaj plaws, cia kuv qhia koj tias nws tau tshoov siab los ntawm txoj haujlwm no: https://www.instructables.com/id/LED-Jewelry/ ua los ntawm jiripraus yog li thov, saib! Thaum kuv thawj zaug sim ua nws txoj haujlwm kuv ua tsis tau phem heev thiab kuv hais rau kuv tus kheej "Vim li cas ho tsis siv PCB los ntawm kev siv cov pas nrig ncaj?" Yog li… TADAM txoj haujlwm no los rau kuv lub siab !!!

Thawj lub hom phiaj ntawm txoj haujlwm no yog ua khoom plig tshwj xeeb rau kuv tus hluas nkauj.

Ntawm daim duab thib 3, koj tseem tuaj yeem pom kuv tus dev, nws lub npe yog Baba thiab kuv xav tias nws hnav txoj saw no zoo kawg nkaus ^^ (Nws zoo li me ntsis zoo li Tony Stark, koj tsis xav li cas?)

Khoom siv

Kuv yuav txhua yam kuv cov khoom los ntawm aliexpress, tab sis kuv paub tseeb tias koj tuaj yeem pom cov khoom siv no thiab cov cuab yeej ntawm lwm lub vev xaib.

• 1x Kev Cai PCB (rau kuv tus kheej ua los ntawm JLCPCB)

  5 PCB rau 2 €

• 6x Multicolors SMD 1206 Led
• 6x SMD 0805 Resistor (phau ntawv piv txwv SMD resistor yuav yog koj tus phooj ywg zoo tshaj plaws hauv ntau txoj haujlwm)
• 1x CR2032 roj teeb
• 1x CR2032 lub roj teeb tuav
• 1x Ib txoj hlua rau txoj saw caj dab

Cov cuab yeej xav tau

• Cov hlau txuas
• Tweezers
• Soldering tin

Yeem cuab yeej

• Soldering flux
• Multimeter
• Tus lwm lossis tus thib peb tes
• Acétone thiab txhuam hniav qub los ntxuav PCB

Kauj Ruam 1: Tsim PCB Ntuag Txiav Siv Fusion 360

Kuv yog tus pib hauv CAO tab sis daim duab kos no yooj yim heev los ua siv Fusion 360.

Kuv siv cov cuab yeej polygon thiab cov qauv ncig los kos qhov no.

Nruab nrab ntawm daim duab 1 thiab 2, Kuv siv lub cuab yeej hu ua Trim thawj zaug, nws tau pab kuv txiav cov kab ntxiv.

Thaum qhov no ua tiav, Kuv tau nyem rau ntawm daim duab thiab nyem rau "Txuag raws li DXF".

Kauj Ruam 2: Ua Tus Txheej Txheem thiab Kev Txhim Kho ntawm PCB Siv Kicad

Yog tias koj xav hloov lub logo sab hauv ntawm PCB, kos koj tus qauv siv Fusion360 lossis Inkscape thiab xa tawm nws ua.dxf cov ntaub ntawv. Tom qab ntawd, koj tuaj yeem import nws ntawm F. Silks txheej ntawm Kicad.

Txhawm rau tig ib qho chaw hneev taw sib txawv (tsis yog kab rov tav lossis ntsug), nyem rau ntawm "e" tus yuam sij ntawm koj cov keyboard thiab taw tes rau nws tib lub sijhawm. Tom qab ntawd, mus rau lub tab hu ua "Kev taw qhia" thiab qhia lub kaum sab xis.

Hauv qab no, koj yuav pom a.rar cov ntaub ntawv sau peb daim nplaub tshev. Ib qho muaj tag nrho cov txheej pdf lwm qhov muaj cov ntaub ntawv gerber thiab qhov kawg muaj cov haujlwm.

Cov ntaub ntawv koj muaj nyob ntawm no muaj qee qhov kev txhim kho piv rau thawj cov ntawv:

• Kuv tau tshem tag nrho cov vias mus rau hauv lub ncoo kom lawv pom tsis tau
• Kuv tau txav tus R1 hneev taw vim kuv pom tias nws ua rau tshem lub roj teeb nyuaj dua

Yog tias koj xav ua tus qauv tsim tib yam, tsuas yog luag thiab xa tag nrho cov ntaub ntawv gerber ntawm lub vev xaib ntawm koj lub chaw tsim khoom PCB nyiam (zoo li JLCPCB lossis PCBWay). Koj tuaj yeem khaws txhua qhov kev teeb tsa ua ntej yog tias koj xav tau tab sis tau kawg koj tuaj yeem hloov pauv PCB xim.

Kauj Ruam 3: Xam qhov tseem ceeb ntawm cov neeg tawm tsam

Qhov no yog tej zaum qhov feem ntau tho txawv tab sis nws yog qhov tsim nyog yog tias koj tsis xav hlawv lub qhov muag ntawm cov neeg uas saib cov saw caj dab ^^.

Kev txiav txim siab txoj kev ci ntsa iab ntawm ib qho xim LED tshwj xeeb yog qhov kev sim zoo nkauj.

Txhawm rau xam tus nqi raug ntawm LED resistor, Kuv siv txoj hauv kev no:

• Kuv txheeb xyuas qhov hluav taws xob ntawm LED siv hom LED ntawm kuv lub ntsuas (hauv daim duab 2 peb tuaj yeem pom 2.571V rau xiav LED)
• Kuv tau sim rau 5 LED xim kuv muaj thiab kuv txiav txim siab tias kev noj 2mA yog qhov txiaj ntsig zoo los pib nrog
• Muab xam los: R = (Ubat - Uled)/A

  Rau qhov xiav LED, cov qauv no tau muab rau kuv R = (3-2.571) /0.002 = 214.5 Ohms, tus nqi ze tshaj uas kuv muaj ntawm kuv phau ntawv yog 220 Ohms yog li kuv tau xaiv 220 Ohms (Saib hauv qab no rau txhua xim)

• Kuv tau ua qhov kev ntsuam xyuas, siv cov tshuaj tiv thaiv kab mob rau lub LED, siv 2 lub xov hlau thiab siv lub roj teeb. Yog tias qhov ci ntsa iab muaj zog heev rau koj, koj tuaj yeem ua rau tus tiv thaiv tus nqi ntau dua, yog tias lub teeb tsaus dhau, txo tus nqi.

Xiav: Uled = 2.571V thiab R = 220 Ohms

Dawb: Uled = 2.614V thiab R = 200 Ohms

Ntsuab: Uled = 2.313V thiab R = 360 Ohms

Txiv kab ntxwv: Uled = 1.887V thiab R = 560 Ohms

Liab: Uled = 1.790V thiab R = 620 Ohms

Kauj Ruam 4: Solder cov Resistors

Tam sim no nws yog lub sijhawm los solder txhua yam.

Pib soldering 6 resistors. Txhawm rau ua tej yam yooj yim dua koj tuaj yeem ntxiv qee qhov ntws yog tias koj muaj qee yam.

Yog tias koj xav tau ntau txoj hlua caj dab, tsis txhob hnov qab siv tus tiv thaiv tsim nyog rau LED.

Kauj Ruam 5: Tuav lub CR2032 Roj Teeb Nrog

Yog tias koj muaj cov dej ntws tawm, ntxiv nws rau ntawm 2 daim ntaub ntawv tom qab ntawd tso lub roj teeb thiab tuav nws hauv txoj haujlwm los ntawm nias nws nrog tus txhuam.

Kauj Ruam 6: Siv cov LEDs

Nov yog sab pom ntawm PCB yog li koj yuav tsum tso cov LEDs ncaj ntawm lawv hneev taw.

Qhov hluav taws xob zoo nyob sab nraum lub pendant thiab qhov tsis zoo voltage nyob sab hauv.

Hauv qhov no, kuv LED muaj ib qho ntsuab kawg uas sawv cev rau qhov tsis zoo.

Kauj Ruam 7: Ntxuav PCB

Thaum tag nrho cov kauj ruam ua kom tiav, koj yuav tsum tau ntxuav PCB.

Kuv siv qee qhov acetone thiab txhuam hniav qub los ntxuav. Thov hnav cov cuab yeej nyab xeeb uas tsim nyog los lis acetone.

Kauj Ruam 8: Khoom plig, Hnav thiab Txaus Siab

Kauj ruam kawg yog tso lub roj teeb CR2032 thaum koj xav teeb lub saw caj dab. Yog tias koj xav tua lub teeb, tsuas yog ntsaws lub roj teeb.

Tam sim no xav tias dawb los ua pendants sib txawv, txaus siab rau sib xyaw xim!

Tsis tas li (thiab koj yuav pom qhov no yooj yim heev), tam sim no tsis tuaj yeem plam ib tus neeg - tib neeg lossis tsiaj- hauv qhov tsaus ntuj siv lub saw zoo nkauj no. Kuv tau sim nrog Baba caum tus miv thiab kuv tuaj yeem ua raws txhua qhov xwm txheej.

Yog tias koj ua koj tus kheej tsim tshwj xeeb, Kuv xav pom nws yog li tsis txhob hnov qab qhia nws hauv kev hais lus ^^.

Muaj ib hnub zoo!
