Nrog cov khw muag khoom zoo li Radio Shack ploj mus, nws nyuaj rau nrhiav cov khoom siv hluav taws xob yooj yim. Lub vev xaib, tshwj xeeb tshaj yog eBay, tau pab zoo, tab sis kev xa khoom tuaj yeem tau txais kim. Cov khoom siv hluav taws xob, xws li VCRs thiab Microwave ncu tuaj yeem yog cov khoom siv, tab sis cov khoom siv hluav taws xob zoo sib xws. Ntau qhov tshwj xeeb tau tsim, lossis tshwj xeeb lawv tsis muaj txiaj ntsig.

Tsis ntev los no, txawm li cas los xij, kev rov ua dua tshiab tau tsim cov khoom siv hluav taws xob zoo hauv qib. Txheeb ib puag ncig koj thaj chaw rau cov chaw siv hluav taws xob rov ua dua tshiab. Cov lag luam no siv cov cuab yeej hluav taws xob los ntawm cov tuam txhab thiab ua lub luag haujlwm coj cov khoom mus rau hauv cov kwj dej rov ua dua tshiab. Lawv feem ntau disassemble cov cuab yeej cais cov hlau sib txawv thiab lwm cov ntsiab lus muaj txiaj ntsig rau hauv ntau lub thoob rau muag rau cov neeg ua kom huv. Cov phiajcim hluav taws xob tau muab pov rau hauv lub thawv loj thiab feem ntau yog shredded rau rov ua dua.

Cov cuab yeej ua lag luam tau tsim los rau tus qauv ntau dua li cov khoom siv hluav taws xob. Tus nqi tsis yog ib qho tseem ceeb, thiab txij li qhov ntim ntawm cov khoom lag luam qis dua, lawv zoo li siv cov txheej txheem txheem.

Ib qho kev rov ua haujlwm loj hauv Houston tsub nqi txog $ 1 ib phaus rau cov laug cam, tab sis feem ntau tsuas yog muab rau kuv thaum kuv qhia lawv cov laug cam yog rau peb cov chaw tsim khoom. Lwm qhov chaw kuv tau mus rau zoo li zoo siab pom cov laug cam mus. Nws yeej tsis tau them kuv rau daim phiaj siv hluav taws xob.

Kauj Ruam 1: Xaiv Boards rau Kev Sau

Ua siab zoo thaum xaiv cov laug cam, nco ntsoov koj yuav tsum tau muab pov tseg pov tseg kom raug. Nws nyob ntawm hom kev tsim qauv uas koj yuav xav ua. Tej zaum koj yuav xav tau tsuas yog los ntawm cov khoom sib dhos, lossis tej zaum koj xav sim nrog qee qhov ntu ntu ntu. Kuv zoo li saib rau lub rooj tsavxwm nrog ntau qhov sib piv sib piv. Lub rooj tsavxwm saum toj no zoo heev. Nws muaj qee qhov kev xav digital, tab sis nws muaj ob peb qhov ua tau zoo op-amps thiab txiav-lauj kaub.

Zam cov laug cam uas ua raws txheej. Cov laug cam no muaj txheej tawv ob sab pem hauv ntej thiab nraub qaum thiab ib feem yog qhov nyuaj rau tshem tawm. Cov txheej txheem tsis zoo yog ib txwm muaj nyob hauv cov tub rog seem

Kauj Ruam 2: Qee Cov Cuab Yeej Koj Yuav Xav Tau

Lub tais hlau yog qhov zoo rau kev ntes cov khoom thaum lawv tawm ntawm lub rooj tsavxwm. Txij li thaum peb yuav siv qhov kub me ntsis kom zoo, lub hnab looj tes vuam zoo yog muaj. Lwm yam tuav cov cuab yeej xws li vises me me, vise-grip pliers. thiab cov neeg tuav lub rooj tsavxwm tuaj yeem ua ke. Tsis txhob hnov qab kev tiv thaiv qhov muag, qhwv ib puag ncig tsom iav zoo tshaj plaws.

Thaum kawg, koj yuav xav tau cov cua sov. Kuv siv lub teeb me me butane, lub teeb loj yog ib qho nyuaj rau tswj. Tsis tas li rab phom kub cua sov ua haujlwm tau zoo.

Koj xav tau txhua yam uas ua haujlwm zoo ntawm kev tuav cov khoom. Koob-qhov ntswg pliers, IC rub tawm, pliers sib koom ua ke, thiab cov cua sov ua haujlwm tau zoo.

Npaj ua haujlwm sab nraud nrog cua daj cua dub. Koj yuav tsum tsoo lub rooj tsav xwm hluav taws xob nrog cua sov ntau, yog li cov iav fiber ntau yuav hlawv thiab haus luam yeeb me ntsis. Kev tiv thaiv qhov muag yog qhov yuav tsum tau ua. Me ntsis ntawm cov kub kub yuav ya txog.

Kauj ruam 3: Pib

Txheeb xyuas txhua lub rooj tsavxwm thiab npaj phiaj xwm rau pawg thawj coj. Nco ntsoov tshem ib qho txuas uas ruaj ntseg cov khoom. Npaj ua haujlwm ntawm cov ntu uas yooj yim tshem tawm ua ntej. Ntau qhov chaw ncaj ncaj poob tawm thaum tshav kub yaj cov laug. Qee lub Cheebtsam, xws li cov neeg tawm tsam, raug kaw rau ntawm pawg thawj coj ua ntej lub rooj tsavxwm raug muab pov tseg. Nws yog qhov zoo tshaj uas tso cov no tseg.

Kauj Ruam 4: Qhov Chaw Yooj Yim Ua Ntej

Ua kom sov lub rooj tsavxwm maj mam thiab sib npaug li sai tau raws li qhov koj xav tshem tawm. Qee lub Cheebtsam yuav cia li poob tawm ntawm lub rooj tsavxwm thaum cov laug yaj. Kuv coj mus rhaub lub rooj tsavxwm tiv thaiv cov ntoo ntoo kom pab lub thawv ntim tau xoob. Tau txais ntau qhov tawm kom ntau li ntau tau siv cov cua sov thiab siv cov txheej txheem.

Kauj Ruam 5: Qhov Me Me tuaj yeem tshem tawm nrog rab koob ntswg ntswg

Sim ua lub qhov ntswg ua ntej. Tshem tawm cov khoom me me nyob ze ICs. Koob lub qhov ntswg kuj ua haujlwm zoo ntawm 8-tus pin DIP pob.

Kauj Ruam 6: Tshem ICs Loj

Cov pliers sib koom ua haujlwm zoo rau rub ICs tawm. ICs feem ntau tsis yog crimped, tab sis muaj cov coj tau khoov sab nraud los tuav tom qab ntawd hauv lub rooj tsav khoom thaum raug muab pov tseg. Qhib IC thiab nws yuav los xoob, yuav luag zoo li rub cov hniav.

Kauj Ruam 7: Muab Cov Khoom SMT Txhuam Txhuam

Qhov SMT tuaj yeem tshem tawm nrog lub qhov ntswg me me. Lwm txoj hauv kev uas ua haujlwm tau zoo yog txhuam lawv tawm ntawm lub rooj tsavxwm nrog txhuam cov kua qaub.
