Kuv lub rooj cob qhia yog qhov muag heev. Txawm hais tias muaj cov xim sib txawv, 80s-Esque cov ntoo ntoo uas npog kuv phab ntsa, nws tsis muaj xim thiab qhov tseeb: LEDs. Ib yam nkaus, kuv nquag ua suab paj nruag thaum siv cov khoom siv hluav taws xob. Qhov no tau txais kuv xav, kuv puas tuaj yeem ua ke ob qho tib si suab paj nruag thiab LEDs kom ua rau kuv chav tsawg dua … tho txawv? Cov lus teb: LED Volume Bar.
Kauj Ruam 1: Theory thiab Op-amp Basics
"chaw thau khoom =" tub nkeeg"
Nws ib txwm ntse los ua tus qauv ua ntej koj ua qhov khoom kawg. Siv cov khoom noj khoom haus tsis txaus thiab lub rooj sib hais lub zog kuv tau nyiag los ntawm lub khoos phis tawj saib xyuas, Kuv hodgepodged ua ke ib qho qauv ua haujlwm ntawm lub ntim ntim. Saib cov vis dis aus kom pom cov qauv hauv kev nqis tes ua!
Kauj Ruam 6: PCB Tsim
Tom qab tsim tus qauv kuv tau tsiv mus rau ua lub tshuab luam ntawv Circuit Board (PCB) rau qhov tsim qauv zaum kawg. Txij li thaum kuv tau ua cov txheej txheem hauv EAGLE, txhua yam kuv yuav tsum tau ua los ua PCB yog hloov los ntawm cov phiaj xwm hom mus rau hom phiaj. Ib zaug nyob rau hauv pawg thawj coj saib, Kuv pib tso txhua qhov tsim nyog resistors, capacitors thiab IC's. Thaum ua tiav, Kuv tau xa cov tooj liab sib txuas rau lawv (pom raws li kab xiav thiab liab hauv daim duab saum toj no) tsim PCB no:
Rub cov ntawv PCB thiab Gerber ntawm no
Kauj Ruam 7: Kev xaj PCBs
Ua tiav nrog PCB tsim, Kuv tau xa tawm pawg thawj coj ua cov ntaub ntawv Gerber. Los ntawm qhov ntawd, nws tau yooj yim ib yam li nyem, nyem, rub tawm, thiab them nyiaj ntawm JLCPCB lub vev xaib, lub tuam txhab Shenzhen raws PCB. Kuv pom zoo JLCPCB vim tias nws muaj txiaj ntsig zoo thiab tsis tshua muaj nqi (uas tuaj yeem qis li $ 2!) Txawm li cas los xij, txawm hais tias JLCPCB pheej yig heev, lub sijhawm thauj khoom yog nyob deb ntawm qhov pom tau zoo. Qhov nruab nrab, nws yuav siv sijhawm 2-3 lub lis piam rau PCBs raug xa tawm siv Tuam Tshoj tshaj tawm. Hauv kuv qhov xwm txheej, vim yog tus mob coronavirus, nws siv sijhawm ntev dua rau kev xa khoom tuaj txog (li 4 lub lis piam).
Kauj Ruam 8: Lub Sijhawm Soldering
Tom qab 4 lub lis piam tos, PCBs tau los txog thaum kawg! Txhua lub JLCPCB cov laug cam tuaj txog hauv lub hnab yas ntim yas. Qhov no ua rau PCBs "tshiab" raws li ua tau, tiv thaiv ib qho muaj peev xwm ntawm oxidization raws txoj kev. Dhau li ntawd, JLCPCB kuj suav nrog khoom plig me me. Lub sijhawm no lawv tau muab me ntsis JLCPCB thumbs up stickers. Qhov no yog ib txwm zoo ntxiv rau.
Tig kuv cov hlau txuas mus rau qhov kub hnyiab 350 ° Celius, Kuv tau ntxeev qhov taub hauv cov laug thiab pib siv tag nrho cov khoom siv hluav taws xob. Soldering nyob rau hauv ib theem zuj zus, ua ntej tuaj rau cov neeg tawm tsam, tom qab ntawd lub capacitors, tus tuav IC tom qab thaum kawg lub zog hloov pauv thiab lub suab ntsaws.
Kauj Ruam 9: Cov Khoom Kawg
Thaum ua tiav nrog cov laug, Kuv tau txheeb xyuas txhua qhov kuv cov ntsiab lus solder, ntsaws rau hauv 12v lub tog raj kheej thiab tua kuv lub teeb. Cia LED qhia pib!
