2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:24

Hauv qhov haujlwm no, kuv yuav qhia koj txoj hauv kev uas kuv tau ua Tsav Tsheb Tswj Tus Kheej Li Cas & Kuv tseem yuav qhia tau tias yooj yim npaum li cas nws tuaj yeem tsim kho qhov Hloov Pauv Hloov Pauv Tsav Tsheb nrog kev pab ntawm IC 555. Cia peb pib!

Kauj Ruam 1: Sau Koj Cov Cheeb Tsam

• IC - NE555 x 1
• POWER MOSFET - IRFZ44N x 1
• CAPACITOR - 1000uF 16V x 1, 100nF x 1, 10nF x 1, 47nF x 2
• RESISTOR - 1kΩ x 3, 10kΩ x 1, 50kΩ Potentiometer x 1
• 2 tus pin header txuas nrog poj niam txuas x 2
• 8 Pin IC socket x 1
• Heatsink (rau Mosfet) & ntsia hlau x 1
• Veroboard lossis tooj liab-clad board x 1
• Knob [rau potentiometer]
• 12V Tsav

Kauj ruam 2: Tsim Circuit Board

Ntawm no koj tuaj yeem pom cov qauv tsim qauv koj tuaj yeem rub tawm nws.

Qhov no nyob ntawm seb hom kev tsim qauv twg koj xav ua nyob ntawm Vero board lossis ntawm tooj liab-clad board & yog tias koj xav tsim lub phiaj xwm ntawm tooj liab tooj liab ua raws cov kauj ruam tom ntej

Kauj Ruam 3: Tsim Tus Txheej Txheem ntawm PCB

• Ua ntej rub tawm cov qauv tsim, ob sab saum toj & hauv qab tsim
• Nqa cov ntawv luam ntawm daim ntawv OHP ntawm lub tshuab luam ntawv laser
• Coj ib lub rooj tsav tooj liab
• Hloov txoj kev txhim kho ntawm lub rooj tsavxwm los ntawm kev siv hlau los hloov tus lej ntawm PCB

Kauj Ruam 4: Etching PCB

Etch PCB nrog tshuaj uas koj siv thiab hom twg uas koj nyiam lossis siv lwm txoj hauv kev los Etch PCB. Nov yog qee cov duab los pab koj tsim lub phiaj xwm.

!! CEEV FAJ

Tshuaj lom neeg muaj kev phom sij

• Hnav cov tsom iav qhov muag kom raug rau kev tiv thaiv qhov muag !!
• Hnab looj tes tas li !! Tsis txhob kov cov tshuaj nrog koj txhais tes liab qab !!
• Hnav daim npog ntsej muag kom npog koj lub ntsej muag.

Kauj Ruam 5: Drilling PCB & Soldering

• Drilling lub qhov ntawm PCB, qhov uas yuav tsum tau teeb tsa, feem ntau ntawm peb nyiam ua
• Mount Cheebtsam ntawm PCB kom zoo
• Tom qab ntawd solder lawv

Kauj Ruam 6: Ua kom muaj zog hauv Circuit

Thaum kawg, sim nws los ntawm Powering Circuit

Ua ntej qhov kos rau luv Circuit Court thiab thaiv kom raug thiab polarity rau VCC & hauv av

Kauj Ruam 7: Ua tiav

Ntxiv qhov thauj khoom raws li lub cev muaj zog sib txawv lub hwj chim rau qhov nrawm uas koj xav tau qhov no yog rau cov khoom me me tsis yog rau lub zog hnyav. Koj tuaj yeem kho qhov no hauv lub tshuab me me xovxwm, uas kuv ua haujlwm, yuav yog kuv cov lus qhia tom ntej.

Koj tau tsim koj tus kheej Qhov Hloov Pauv Hloov Pauv Tsav Tsheb uas yog qhov me me thiab ua tau zoo

Qhov ntawd zoo heev

Kauj Ruam 8: Hloov kho tshiab

Kuv ua tiav kuv li DIY PCB laum xovxwm tshuab, koj tuaj yeem tshawb xyuas nws
