Nyob Zoo Cov Menyuam, Nov yog kuv thawj qhov kev qhia ua haujlwm. ntawm no kuv yuav qhia koj li cas kuv tau ua kuv tus kheej tus nqi qis LM317 Lub rooj zaum fais fab mov. Kuv vam tias koj yuav txaus siab rau nws.

Kauj Ruam 1: Xav Tau Cov Khoom Hluav Taws Xob:

Los ntawm kev sab laj LM-317 cov ntaub ntawv, peb tuaj yeem paub qhov twg xav tau:

1-LM317: Aliexpress

2- 1x0.1 uF capacitor, rau du Vin:

3- 1x1uF capacitor, rau smooth Vout: Aliexpress

4-1x10uF capacitor, rau Cadj (raws li daim ntawv qhia).

5-2x1N4002 diodes: Aliexpress

6-1x240 ohm resistor, Kuv siv 1x150 ohm+1x100 ohm hauv koob: Aliexpress

Aliexpress cov khoom siv tsis sib haum

7-1x5K ohm potentiometer: Aliexpress

8-Mini DC Voltmeter: Aliexpress

9-Protype PCB: Aliexpress

10-Xov: Aliexpress

11-Cov khoom siv yas yas yas: Aliexpress

12-2xAligator clips xov hlau: Aliexpress

13-Cov cua sov (Kuv khaws kuv li ntawm PCB qub): Aliexpress

14- DC Barrel fais fab txuas txuas: Aliexpress

15-txhua lub PC lossis laptop lub zog siv (Kuv siv kuv lub laptop qub 19V lub zog hloov pauv).

Cov cuab yeej siv:

1-Soldering hlau ua tiav cov khoom siv: Aliexpress

2- Qhov thib peb txhais tes pab pab clamp: Aliexpress

3-Multimeter (ib qho).

4-Kub kua nplaum phom: Aliexpress

Kauj Ruam 2: Kuaj Circuit Court ntawm Breadboard:

Txhua tus kiv cua ntawm cov khoom siv hluav taws xob yuav tsum ntsuas lub Circuit Court ua ntej pib siv lub PCB kom raug. Kuv siv suav nrog Daim Ntawv Teev Npe kab kos duab kom paub kuv qhov haujlwm. xav tias dawb rau google rau LM317 lossis rub nws los ntawm hauv qab no.

Thaum koj tig lub potentiometer koj yuav tsum pom qhov hloov pauv ntawm lub multimeter.

Kauj Ruam 3: Cov Khoom Siv Hluav Taws Xob:

Kuv tau siv tag nrho cov khoom siv raws li LM317 cov ntawv teev tseg ntawm cov qauv PCB. Kuv siv qee cov xov hlau kom ua tiav kev sib txuas hla.

Sim siv, piv txwv li sab laug ntawm PCB rau qhov tso tawm (qhov twg kuv tau siv piv txwv li tus nab kuab txuas xov hlau) thiab ib sab rau kev nkag (qhov twg kuv tau siv lub qhov txuas txuas txuas).

Thaum ua tiav cov khoom siv nruab ib lub rhaub dej sov ntawm LM317 IC nrog cov ntsia hlau me me thiab txiv ntseej.

Kauj Ruam 4: Txhim Kho Sab Hauv Cov Khoom Yas:

Tom qab siv cov laug, Kuv tau teeb tsa PCB ua hauv lub thawv yas thiab muab lo rau hauv qhov chaw nrog kua nplaum kub.

Kuv tau xaum lub qhov nyob rau sab xis rau DC lub tog raj txuas nrog cov hlau qub qub (Kuv tsis muaj lub laum hluav taws xob) thiab muab lo rau nws. Kuv tau ua zoo ib yam rau Vout tus nab kuab clips tom qab thawb lawv sab nraum lub thawv ntawv.

Kuv tau hlais lub qhov ntawm lub hau npog rau lub hwj chim thiab ua kom nws ruaj khov nrog cov txiv ntoo thiab kua nplaum kub. Nruab ib lub pob qhov rooj rau nws.

Ntawm lub hau npog, kuv tau siv tib lub tshuab hlau los ua lub qhov hluav taws xob tom qab ua qhov ntsuas xav tau. Kuv tau ua yuam kev thaum ua haujlwm ntawm lub qhov plaub fab rau lub voltmeter. Kuv tsis muaj cuab yeej txiav lossis pom. thov txim rau qhov ntawd.

Rau qhov ntsuas hluav taws xob kuv tau ua raws tus muag khoom kos duab. (saib duab).

Kauj Ruam 5: Xeem Lub Rooj Tog Zaum Fais Fab:

Tom qab kaw lub thawv yas thiab ruaj ntseg nws nrog cov ntsia hlau, Kuv ntsaws rau hauv lub khoos phis tawj qub lub zog hloov pauv hauv lub tog raj … thiab "voila" nws ua haujlwm raws li xav tau.

Kuv sim lub rooj zaum fais fab mov nrog cov khoom sib txawv. Kuaj nrog lub ntsuas ntsuas kom pom ntau npaum li cas yog qhov voltage thiab amperage. yog tias tsis raug, sim ua kom zoo rau lawv sab nraub qaum dub 100v multimeter. Muaj cov potentiometers me me rau qhov hluav taws xob thiab amperage.

Kauj Ruam 6: Pom:

Kuv V1.0 lub rooj zaum fais fab mov xav tau qee qhov kev txhim kho:

1- Qhov kev txiav zoo yog qhov txaus ntshai vim tsis muaj cov cuab yeej tsim nyog, yog li ntawv tom ntej yuav raug txhim kho.

2-Ua kom zoo dua saib thiab lub qhov rooj ergonomic.

3- Ua tus V2.0 tshiab siv qhov ua tau zoo dua DC-DC kauj ruam nce-nqis nqis phaw hloov pauv.

Thiab ntawm no peb qhov project los txog qhov kawg. Vam tias koj nyiam nyeem ntawv. xav tias dawb los tawm tswv yim. Los ntawm koj cov kev xav peb vam meej. Ua tsaug.
