Yog tias koj yog tus tsim khoom koj yuav tsum nyiam ua cov khoom. Peb txhua tus ua! Tsis yog nws txaus thaum ib tus neeg nug koj tias koj ua dab tsi thiab koj zoo li "Kuv tsuas yog ua tej yam txias nrog kuv txhais tes"? Thaum koj tab tom mus rau kev sib tw, tsev kawm lossis chaw tsim khoom ncaj ncees (Kuv xav kom muaj ib hnub) koj xav qhia txhua tus neeg nyob ib puag ncig tias koj yog tus tsim khoom. Vim li ntawd, kuv xav tias qee yam ntawm cov cim LED yuav txias. Tej zaum kuv yuav tsum luam 3D ib qho thiab muab qee qhov LEDs tso rau hauv? Tsis yog, tsis txias txaus. Yuav ua li cas hais txog PCB loj nrog ntau LEDs uas tau teeb tsa hauv qee cov ntawv cia peb hais "Kuv MUAJ STUFF"? Uas suab zoo meej! Yog li ntawd yog vim li cas kuv ua nws. Cov cim npe uas yog li cas kuv hu nws yog txoj haujlwm yooj yim heev rau cov pib, yog li yog tias koj xav pib nrog cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob koj tuaj yeem ua los ntawm kev ua qhov haujlwm no. Muaj ntau yam uas yuav tsum tau siv tshuaj yaj yeeb (yuav luag 100 LEDs) tab sis txhua yam ntawm cov khoom siv (tshwj tsis yog ib qho uas xav tau) ntawm THT (dhau los ntawm qhov siv tshuab) yog li cov ntawd yooj yim rau yaj. Yog tias koj xav kom muaj lub cim txias LED nyeem txuas ntxiv:)

JLCPCB 10 cov laug cam rau $ 2:

Kauj Ruam 1: Peb Yuav Xav Li Cas?

Cia peb pib nrog ntu uas peb yuav xav tau los ua qhov haujlwm no. Tsis muaj ntau qhov sib txawv sib txawv tab sis muaj ntau ntawm LEDs. Txhawm rau txuag qee qhov nyiaj ntawm lawv koj yuav tsum nrhiav qhov pheej yig tshaj plaws, sim nrhiav lawv hauv Suav teb. Cov kev ntsuas ntawm lawv yog 2V thiab 5 hli xim yog nyob ntawm koj. Yog tias koj xav tau koj tseem tuaj yeem yuav cov khoom siv ua tiav nrog txhua ntu, tshwj tsis yog lub qhov (socket) USB lossis PCB nkaus xwb ntawm no ntawm Tindie:

www.tindie.com/products/Nikodem/maker-badge-kit/

PCB yog ib feem loj ntawm txoj haujlwm no yog li yog tias koj tsis muaj ib qho nws yuav nyuaj ua nws, tab sis koj tuaj yeem sim ua nws ntawm daim ntawv tiv thaiv. Yog tias koj xav ua PCB ntawm koj tus kheej koj tuaj yeem nrhiav txhua cov ntaub ntawv hauv cov kauj ruam tom ntej.

Thiab ntawm no yog yam peb yuav xav tau:

• PCB
• 100X LEDs 5mm 2V 0.02A
• 6 X 10 Ohm resistor
• Breakaway headers
• Hloov
• *micro USB qhov (xaiv tau)

Kauj Ruam 2: Schematic, PCB thiab Qee Zauv …

Txoj haujlwm no nyuaj heev los ua ntawm protoboard lossis breadboard yog li PCB yog txoj hauv kev zoo tshaj. Yog tias koj xav ua PCB ntawm koj tus kheej koj tuaj yeem pom txhua cov ntaub ntawv nyob ntawm no. Kuj tseem muaj cov phiaj xwm nrog txhua qhov kev sib txuas, kuv xav piav qee qhov ntxiv vim li cas txhua yam txuas nrog zoo li no. Raws li koj tuaj yeem pom ntawm cov txheej txheem (saib cov duab saum toj no) muaj 6 qhov thaiv 16 LEDs hauv ib qho. Hauv txhua qhov thaiv, muaj 2 LEDs txuas nrog ua ke thiab tom qab ntawd 8 ntawm cov uas txuas nrog ua ke. Ua ke ntawd yog 16 LEDs thiab qhov ntawd yog ib qho thaiv. Koj tuaj yeem nug yog vim li cas qhov kev sib txuas no ntse heev. Vim yog cov neeg tawm tsam, Kuv xav kom muaj peev xwm nws nrog 5V, 2 LEDs txuas nrog hauv kab tuaj yeem siv nrog 4V (2V txhua) yog li peb xav tau tus tiv thaiv uas yuav siv 1V. Tab sis txhua tus LED siv 0.02A ntawm lub zog uas sib npaug rau 20mA yog li yog tias koj yuav muab 0.02 los ntawm 48 (peb muaj 96 LEDs txuas nrog ua ke ua khub thiab tom qab ntawd sib luag, qhov no yog vim li cas 48) peb muaj 0.96A kom paub lub zog siv peb yuav tsum muaj ntau qhov hluav taws xob los ntawm tam sim no (P = I*U) P = 4.8W thiab lub zog ntawm tus tiv thaiv yog sib npaug rau 0.96W. Cov neeg tawm tsam nrov tshaj plaws tuaj yeem tso tawm qhov siab tshaj 0, 25W uas yog vim li cas peb thiaj tsis tuaj yeem txuas tag nrho cov LEDs rau ib tus tiv thaiv. Nws muaj peev xwm txuas tau 4 tus tiv thaiv sib xws kom muaj 1W ntawm lub zog loj tab sis peb nyob ze rau nws yog li cov neeg tawm tsam tuaj yeem ua kom sov ntau lossis txawm tias hlawv. Peb tsis xav kom qhov ntawd tshwm sim. Kuj tseem muaj lwm qhov teeb meem yog tias ib tus f cov neeg tawm tsam yuav tawg yuav muaj lub zog ntau dhau rau ntawm lawv tias lawv yuav tawg ib yam thiab nws tuaj yeem tsoo peb cov LEDs, peb tsis xav hlawv 100 LEDs. Txoj hauv kev zoo tshaj plaws hauv kuv lub tswv yim los ua nws yog faib lawv rau rau rau ntu thiab txuas lawv raws li qhia hauv cov txheej txheem, txoj kev ntawd peb muaj 2 LEDs hauv kab thiab 8 ntawm cov khub ntawd ua ke (ua ke 16 LEDs) yog li tam sim no ntawm cov thaiv no 0.02*8 = 0.160A thiab lub zog ntawm tus tiv thaiv yuav nyob ib puag ncig 0.160W, lub zog siab tshaj plaws ntawm tus tiv thaiv yog 0.250W yog li nws muaj kev nyab xeeb heev los txuas nws thiab peb siv tsuas yog 6 tus tiv thaiv. Qhov ntawd yog ntau tus lej, Kuv tau ua qhov zoo tshaj plaws los piav qhia vim li cas kuv thiaj ua li ntawd, Kuv vam tias koj nkag siab yam tsawg kawg ib yam:) Kuv cog lus tias yuav tsis muaj lej ntxiv, cia peb pib ua!

Kauj Ruam 3: Soldering USB Socket (xaiv tau)

Qhov no yog nyob ntawm yeem vim tias nws nyuaj heev rau cov khoom no tshwj xeeb tshaj yog tias koj tsis muaj kev paub dhau los. Pom tseeb ua tsaug rau ntu no nws yog qhov yooj yim heev rau lub zog rau qhov no, koj tuaj yeem tsuas yog siv lub xov tooj them lub xov tooj xwb, tab sis rau cov pib tshiab, tej zaum nws yuav tsis meej pem. Kuv yuav tham me ntsis ntxiv txog kev ua kom muaj zog ntawm qhov no hauv cov kauj ruam tom ntej yog tias paub yuav ua li cas txhawm rau lub qhov (socket) no tsuas yog ua nws, yog tias tsis txav mus ntxiv.

Kauj Ruam 4: Soldering Resistors

Muaj rau tus resistors rau solder. Kuv cov lus qhia yog txhawm rau lawv sab nraum qab ntawm PCB lossis protoboard kom lawv tsis pom rau tus neeg siv. Muab lawv tso rau hauv qhov chaw thiab cov laug, yooj yim li ntawd:) Koj tuaj yeem pom ntawm cov duab saum toj no yuav ua li cas nws yuav tsum zoo li, yuav tsum tsis txhob siv cov laug ntau dhau tab sis tag nrho lub qhov yuav tsum tau npog nrog cov laug.

Kauj Ruam 5: Soldering 100 LEDs

Nws yog lub sijhawm rau kev lom zem ib feem:) 100 LEDs, zoo 96 kom raug. Zoo li ntau tab sis kev siv tooj liab yog qhov txaus siab heev thiab lom zem ua. Soldering tag nrho cov LEDs ib zaug tsis yog lub tswv yim zoo, koj yuav tsum muab txhua tus ntawv cais lossis txawm tias tsuas yog ib feem ntawm cov ntawv xwb. Yog tias koj tsuas yog pib nrog cov laug laug ib lub LED thaum lub sijhawm, nco ntsoov tias nws txuas nrog rau lub rooj tsavxwm zoo kawg nkaus thiab koj txaus siab rau koj cov laug, tom qab ntawd txav mus rau LED tom ntej. Nws yog ib qho tseem ceeb heev kom pib maj mam thiab sim txhim kho koj cov laug ntawm txhua feem. Tias yog vim li cas txoj haujlwm no zoo rau cov pib tshiab - muaj ntau qhov sib xyaw. Nco ntsoov txog LED polarity luv luv ceg tsis zoo thiab ntev ceg yog qhov zoo. Muaj ib txoj ntug ncaj ntawm sab ntawm LED kom paub tseeb tias nws sib phim nrog txoj kab ncaj ntawm PCB. Thaum koj tau siv qee cov LEDs nco ntsoov txiav tawm ntawm lawv ob txhais ceg, koj yuav muaj chaw ntau dua thiab nws yuav yooj yim dua rau tom ntej.

Kauj Ruam 6: Txiav Tawm Ob txhais ceg ntawm LEDs

Thaum koj ua tiav qhov muag kom nco ntsoov txiav tawm tag nrho ob txhais ceg ntawm LEDs thiab cov tiv thaiv, peb tsis xav kom ntsaum luv ntawm no. Koj tuaj yeem ua nws nrog cov cuab yeej uas tuaj yeem txiav txawm txiab yuav ua.

Kauj Ruam 7: Kev Hloov Qhov Muag thiab Lub Taub Hau Tshem Tawm

Ob qhov kawg uas peb yuav tsum tau muab sib dhos yog qhov hloov pauv thiab tshem tawm lub taub hau. Qhov hloov pauv nyob ntawd kom tig lub cim rau thiab tawm, tshem tawm lub taub hau yog kom muaj zog. Lwm txoj haujlwm ntawm qhov kev hloov pauv no yog tias nws tuaj yeem sawv ncaj ua tsaug rau nws yog li koj tsis xav tau tus tuav lossis txhawb nqa. Txhawm rau kom nws qis profile Kuv siv khoov taub hau tawg (Kuv paub tseeb tias nws tsis yog lub npe tsim nyog rau qhov ntawd tab sis koj paub tias kuv txhais li cas). Solder ob qho tib si ntawm cov khoom siv sab nraub qaum, ib sab ib yam li cov tiv thaiv.

Kauj Ruam 8: Yuav Ua Li Cas Fais Fab?

Raws li kuv tu siab hauv theem ob txoj hauv kev zoo tshaj plaws los siv nws yog siv lub xov tooj them lub xov tooj tab sis vim tias nws nyuaj rau txuas lub qhov (socket) rau nws Kuv tau ntxiv lub hauv paus cais kom koj tuaj yeem siv zog txawm li cas los xij koj xav tau. Koj tuaj yeem siv txhua yam ntawm 4V thiab 5V (ci ntsa iab yuav me me rau qis zog). Cov khoom siv hluav taws xob, roj teeb, lub hnub ci cell, 1S LI-PO roj teeb txawm tias lub rooj zaum raug tshem tawm lub hwj chim zoo li kuv ua:)

Kauj Ruam 9: Xaus

Hauv kuv lub tswv yim, txoj haujlwm no tau ua tiav zoo kawg nkaus! Kuv nyiam LEDs thiab kos npe ua nrog LEDs txias, nws zoo li me ntsis zoo li lub cim neon:) Qhia rau kuv paub koj xav li cas txog txoj haujlwm no hauv cov lus thiab tsis txhob hnov qab ua raws kuv ntawm kev tshaj xov xwm:
