Kauj Ruam 3: Tsim Circuit Court thiab PCB Layout

Daim duab qhia chaw ntawm lub ntsuas ntsuas lub suab muaj peb ntu, xws li: lub tshuab tso suab lub microphone, lub zog siv hluav taws xob thiab kev hloov kho, ntsuas qhov qhia tawm nrog lub zog tso tawm theem.

Cov cuab yeej no ua haujlwm ib txoj hauv kev uas tom qab ua kom nrov nrov thiab ua kom lub suab nrov ntawm lub microphone hloov pauv mus rau qhov hluav taws xob nrog qib sib piv rau lub teeb liab. Qhov ntsuas hluav taws xob no tau siv rau tus lej sib piv ntawm txhua tus uas ua rau tus neeg ua haujlwm sib piv.

Lub hauv paus tseem ceeb ntawm tus tswj hwm yog lub tshuab hluav taws xob sawtooth uas yog sib xyaw nrog lub zog hluav taws xob. Nrog nws qhov kev pab hais kom tig lub cim tsim hluav taws xob, thiab yog tias muaj lub cim sib piv, lub zog siv rau lub teeb ntawm kab.

Kauj ruam 4: Choke Manufacturing

Tam sim no cia peb tsim cov tshuaj tiv thaiv antijam.

Peb xav tau cov xaim tooj liab xaim nrog txoj kab uas hla ntawm 1 hli, ntev li ntawm 1.350 hli thiab lub hauv paus tub ntxhais uas ua los ntawm cov hmoov hlau uas muaj lub cheeb sab nraud ntawm 30 hli thiab sab hauv txoj kab uas hla 20 hli.

Peb yuav tsum tau cua 38 tig ntawm tooj liab xaim nyob ib ncig ntawm cov tub ntxhais toroidal.

Peb tuaj yeem siv qhov thauj khoom mus txog 1000 watts nrog kev pab ntawm qhov txhaws.

Kauj Ruam 5: Kev teeb tsa Cov Xov Tooj Cua ntawm Cov Tswj PCB

Tom ntej no, cia mus txuas ntxiv rau kev teeb tsa cov khoom siv xov tooj cua ntawm lub rooj tsav xwm tswj hwm.

Kauj Ruam 6: Kev teeb tsa ntawm Circuit Board Board

Tom qab txhim kho txhua lub xov tooj cua, koj yuav tsum teeb tsa lub rooj tsav xwm tswj hwm.

Siv digital multimeter nrog txwv kev ntsuas ntawm 20 V (DCV), kho qhov sib txawv resistor Aj1 kom qhov ntsuas hluav taws xob ntawm lub capacitor C3 yog txog 2.9 volts.

Tom ntej no, siv qhov sib txawv resistor Aj2 koj xav tau teeb tsa qib siab tshaj plaws ntawm lub teeb sab saud kom lawv pom kev ntawm lub suab siab tshaj plaws.

Kauj Ruam 7: Kev Pom Duab 3D

Txhawm rau tsim 3D kev pom thiab kos duab ntawm lub cim qhia lub cev, KOMPAS 3D program tau siv. Lub cev ntawm lub cuab yeej muaj 8 ntu. 3 hli pob tshab organic iav tau siv los tsim lawv. Txhua daim duab tau hloov pauv mus rau DXF hom ntawv thiab xa mus rau ib lub tuam txhab txiav ntawv.

Kauj Ruam 8: Sib dhos ntawm Pawg Tswj Xyuas Vaj Huam Sib Luag Nrog Cov Vaj Huam Sib Luag Hauv Qab

Ntxig cov ntawv tooj dag M3 6 hli ntev rau hauv lub qhov ntawm lub rooj tsav xwm tswj hwm thiab kho lawv siv cov txiv ntoo.

Tom qab ntawd, muab lub rooj tsav xwm tswj hwm thiab lub cev hauv qab ua ke siv cov ntsia hlau M3.

Kauj Ruam 9: Kev Npaj Hluav Taws Xob rau Kev Sib Txuas

Tom ntej no, npaj cov xov hlau rau kev txuas ntxiv ntawm cov roj teeb nrog cov tswj hluav taws xob.

Ua ntej soldering, koj yuav tsum tshem tawm tag nrho cov rwb thaiv tsev thiab tin cov xov hlau.

Kauj Ruam 10: Txhim Kho Lub Teeb Teeb Lub Teeb

Txhawm rau teeb lub teeb roj teeb peb yuav siv tus tuav tuav nrog lub adapter txuas ntawm European tus qauv E27 ua los ntawm cov yas dawb uas tiv taus cua sov.

Ua ntej txhim kho cov tuav ntawm lub puab sab hauv ntawm lub cev, koj yuav tsum tshem lub hau npog sab saum toj.

Ntxig cov ntsia hlau M3 rau hauv los ntawm lub qhov ntawm tus tuav rau cov roj teeb thiab txuas lawv los ntawm sab nraum qab siv cov txiv ntoo.

Kauj Ruam 11: Txhim Kho Cov Nruab Nrab thiab Sab Saum Sab Hauv Sab Hauv Ntug

Nruab nruab nrab thiab sab sauv lub cev rau sab ntug. Ntxig cov txiv ntoo rau hauv lub qhov qhov ntawm ob sab. Tom qab ntawd, muab cov ntu ua ke siv cov ntsia hlau M3.

Tom ntej no, teeb ib qho ntawm cov vaj huam sib luag sab ntawm ntug nruab nrab.

Kauj Ruam 12: Txhim Kho Qab Hauv Qab Nrog Cov Tswj Xyuas Pawg ntawm Sab Vaj Huam Sib Luag

Ntxig lub rooj sib txoos ntawm lub rooj tsav xwm tswj hwm thiab sab qis ntawm lub cev hauv qhov dhau los ntawm cov kab sib dhos ua ke ntawm sab vaj huam sib luag.

Tom qab ntawd, nruab ob sab vaj huam sib luag.

Kauj Ruam 13: Kev Txhim Kho Cov Hluav Taws Xob rau Lub Caij Nplooj Ntoos Hlav ntawm Cov Teeb Teeb

Mount cov xov hlau mus rau lub caij nplooj ntoo hlav ntawm cov neeg tuav lub teeb los ntawm lub qhov nyob ntawm ntug sab hauv ntawm lub cev.

Kauj Ruam 14: Txhim Kho Cov Hluav Taws Xob Los Ntawm Txhua Tus Kheej Qib Rau Hauv Qhov Hau

Ntxig cov xov hlau los ntawm txhua qib ib leeg ntawm qhov ntsuas lub suab mus rau hauv lub qhov dav ntawm qhov kev tswj hwm pawg thawj coj saib xyuas kho lawv nrog cov ntsia hlau.

Kauj Ruam 15: Txuas Hluav Taws Xob Txuas Nrog Rocker Hloov

Txuas lub qhov hluav taws xob rau lub rocker hloov siv cov xov hlau thiab teeb nws rau hauv lub qhov nyob sab nraub qaum ntawm lub cev.

Tom qab ntawd, cia kho lub vaj huam sib luag tom qab.

Kauj Ruam 16: Txhim Kho Lub Vaj Huam Sib Luag Pem Hauv Ntej

Tom ntej no, teeb tsa thiab khawm lub vaj huam sib luag pem hauv ntej nrog rau lwm lub cev.

Muab cov hniav zoo nkauj nrog rau sab hauv txoj kab uas hla ntawm txoj kab uas hla 6 hli ntawm cov potentiometers.

Kauj Ruam 17: Txhim Kho Cov Teeb Teeb Xim Teeb

Tom ntej no, ntsia hlau 25-watt xim teeb roj teeb rau hauv tus tuav. Coj mus rau hauv tus account tag nrho lub zog thauj khoom thaum xaiv fuse F1.

Tom qab ntawd tig lub wipers ntawm potentiometers P1 thiab P2 mus rau sab xis kom txog thaum lawv nres. Tom qab txuas lub zog txuas, ntau lub teeb yuav tsum teeb, tshwj xeeb tshaj yog yog tias lub suab nrov ib puag ncig tseem ceeb.

Yog tias qhov ci ntawm lub teeb qis dua thaum koj maj mam tig lub hwj chim tuav P1, tus tswj hwm ua haujlwm tau zoo.

Tom qab ntawd koj yuav tsum kho qhov rhiab heev ntawm lub microphone siv lub zog P2.

Kauj Ruam 18: Kev Ua Haujlwm

Ua tsaug rau txhua tus saib cov vis dis aus thiab nyeem kab lus. Tsis txhob hnov qab nyiam nws thiab sau npe mus rau "Hobby Home Electronics" channel. Qhia rau phooj ywg. Ntxiv mus yuav muaj cov kab lus thiab cov vis dis aus txaus nyiam dua.
