Lub Hwj Huam Muab Khoom yog ib qho cuab yeej tseem ceeb tshaj plaws uas tinker tuaj yeem muaj. Nws tso cai rau peb kom yooj yim sim cov qauv hluav taws xob yam tsis tas yuav ua khoom siv tas mus li rau nws. nws tso cai rau peb kuaj cov kab hluav taws xob hauv txoj kev nyab xeeb vim qee qhov khoom siv hluav taws xob muaj cov yam ntxwv xws li dhau kev tiv thaiv tam sim no, tiv thaiv luv Circuit Court thiab ntau ntxiv! Tab sis cov khoom siv hluav taws xob tuaj yeem kim kim sai thiab rau cov pib ua lag luam hauv qee yam kim li tsis yog qhov kev xaiv. Tsis txhob ntshai kuv nyob ntawm no hnub no los qhia koj txog yuav ua li cas thiaj ua tau lub rooj sib tw lab lab lub zog uas yooj yim thiab pib ua phooj ywg los ua. Siv LM317T linear voltage transistor!
Kauj ruam 1: Sau cov khoom siv
Raws li qhov no yog txoj haujlwm pib ua neeg feem coob yuav muaj cov ntaub ntawv uas peb xav tau nyob hauv tsev! Cov ntaub ntawv no tuaj yeem khaws tau yooj yim los ntawm lub khoos phis tawj qub qub xws li lub tshuab hloov pauv
Nov yog cov npe khoom siv
Transformer (txhua lub tshuab tuaj yeem siv tau tab sis kuv yog 24V 3 amp ib qho)
PCB (nws yog ib qho dawb hauv daim duab uas muaj txheej Photoresist tab sis koj tuaj yeem siv pcb zoo ib yam)
LM317T (1pcs)
5k ohm potentiometer.
Potentiometer pob qhov rooj
cov kab
ac ntsaws (Kuv khaws kuv tus kheej)
electrolytic Capacitor (txhua tus nqi kuv siv 47μF)
Diodes (1N4001) (4pcs)
Hloov
220v coj (nyob ntawm koj cheeb tsam qhov hluav taws xob qhov hluav taws xob) (yeem)
Kauj Ruam 2: PCB Sijhawm
Peb tab tom yuav ua 2 pcb rau txoj haujlwm no 1 yog FULL BRIDGE RECTIFIER !!!! thiab LM317T Circuit.
Tus choj txuas tag nrho yog tus uas yuav tig peb lub zog hluav taws xob los ntawm lub tshuab hloov pauv mus rau siv DC qhov hluav taws xob kom muaj zog rau peb cov hluav taws xob.
LM317T Circuit Court ntawm qhov tod tes yog qhov uas yuav tswj hwm thiab kho qhov hluav taws xob mus rau hauv Circuit Court.
(Hauv cov duab kuv qhia piv txwv PCB tsim uas koj tuaj yeem siv tau)
Kauj ruam 3: Etch Koj Sketch
Txawm hais tias koj kos koj lub PCB lossis luam tawm rau nws nws yog lub sijhawm los kos!
Siv Ferric Chloride tso nws rau hauv lub khob yas uas koj tuaj yeem ntsaws koj lub PCB thiab tshem tawm cov tooj liab ntau dhau (Ceeb Toom: Ceev faj Ferric Chloride ua rau cov khaub ncaws ntub thiab ntseeg kuv ib zaug nws cov xim nws nyob ntawd mus ib txhis!)
Kauj Ruam 4: Lub Sijhawm Solder
Ua raws li daim duab schematic saum toj no los tso koj cov khoom hauv qhov kev txiav txim raug!
TSWV YIM: Nco ntsoov ib txwm kuaj ob zaug ua ntej yuav siv nws yuav ua rau koj lub neej yooj yim dua!
(Yog tias koj ua raws li kuv li PCB tsuas yog ua raws cov khoom tso rau saum toj no)
Kauj Ruam 5: Txuas Nws
Kev txuas nws yog ib qho yooj yim xws li txuas qhov zoo rau qhov zoo thiab tsis zoo rau qhov tsis zoo!
Tswv yim: siv koj lub sijhawm hauv kev tswj hwm hlau nws yooj yim dua rau kev debug yog tias muaj teeb meem hauv kev thaiv kab.
Hauv kev hloov pauv yuav tsum tau ceev faj kom xaim nws mus rau qhov ntsuas hluav taws xob zoo ib yam li piv txwv 0-220V rau kuv cheeb tsam nws hloov pauv ntawm lub tebchaws twg uas koj nyob.
Kauj ruam 6: Ua tiav
Txoj Haujlwm Zoo!
Koj tuaj yeem txhim kho qhov haujlwm no los ntawm kev ntxiv qhov hluav taws xob thiab cov ntsuas tam sim no, Cov cua sov, thiab ntau ntxiv!
Kuv vam tias qhov haujlwm no yuav pab thiab pab koj tau ntau xyoo ua tus xav!

USB Hloov Pauv Hloov Voltage Fais Fab Khoom: 7 Kauj Ruam (nrog Duab)
USB Hloov Pauv Hloov Pauv Lub Hwj Huam Fais Fab: Kuv tau muaj lub tswv yim rau USB siv lub zog hloov pauv hloov pauv tau rau qee lub sijhawm. Raws li kuv tau tsim nws, Kuv tau ua nws me ntsis ntau yam tso cai rau tsis yog siv USB nkaus xwb, tab sis txhua yam los ntawm 3 VDC txog 8 VDC ntawm USB ntsaws lossis ntawm txiv tsawb ntsaws ntsaws. Cov zis siv t
Hloov Pauv Hloov Pauv Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob: 3 Cov Kauj Ruam
Hloov Pauv Hloov Pauv Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob: Tsim kom muaj kev tswj hwm lub zog hluav taws xob rau lub tsub hluav taws xob lossis lwm daim ntawv thov hluav taws xob siab. Txoj haujlwm no tuaj yeem raug nqi tsawg dua $ 15 thiab koj yuav muaj peev xwm nce mus txog 1000V thiab tuaj yeem kho qhov tso tawm los ntawm 0-1000V+. Qhov kev qhia no
