Yog tias koj yog tub ntxhais kawm hluav taws xob, nyiam tshaj plaws lossis tshaj lij koj yeej muaj teeb meem ib txwm ntawm kev muab qhov hluav taws xob raug rau koj li khoom siv thiab cov khoom siv hluav taws xob. tso tawm 1volts rau 17volts los ntawm 12volts 1000mA cov tswv yim (tus qauv dc adapter). Qhov tseem ceeb tsis yog kuv li tab sis lwm qhov tshaj li nws yog txhua yam kuv ua haujlwm, kuv kuj hloov 1N5402 nrog 1N4007 vim kuv tsis muaj thawj zaug muaj, 4007 yog lub zog ntau dua li 5402 thiab nws tuaj yeem ua haujlwm tau txog 1000mA (uas yog peb qhov ntsuas tam sim no), tsis yog cov diode no txhua yam uas yooj yim mus nrhiav thiab muaj nyob hauv cov khw hluav taws xob feem ntau.

Kauj ruam 1: Cov ntaub ntawv

Cov ntaub ntawv hauv qab no xav tau rau txoj haujlwm no: 1x LM317 regulator2x 1N4001 diode1x 1N4007 diode1x 1k resistor (rau coj) 1x 220R resistor (R sawv rau 0 sab tes zeros ie ohms) 1x 18k resistor1x 470uF 40+ v electrolytic capacitor (qhov ntsuas qis kawg yog 40v txhua yam siab dua yog ok) 1x 470nF ceramic capacitor1x 4.7uF 40+ v electrolytic capacitor1x 10uF 40+ v electrolytic capacitor1x 100n ceramic capacitor1x LED (kuv siv 5v xiav LED yog li txhua yam ntawm 1.5 thiab 5 yuav ua haujlwm thiab muaj xim ntawm chav kawm) 1x ON-ON hloov (3 txhais ceg) 1x DC adapter jack1x 10k potentiometer !!! LINEAR !!! 1x 4x7 cm blank PCBOthers: Ferric Chloride etchantAcetoneGlossy paperI lub tswv yim lossis tsuas yog muaj tswv yim:) Cov cuab yeej: Cov cim tiv thaiv dej (rau kho cov kab tawg) Laser Tshuab Luam Ntawv PCB DrillSolder hlauSolderCloth Iron

Kauj ruam 2: Schematics

Raws li kuv tau hais ua ntej qhov no tsis yog kuv li haujlwm, kuv tsuas yog ua rau pom qhov xwm txheej no thaum tshawb xyuas lub vev xaib.

Kauj Ruam 3: PCB Tsim

Qhov no yog PCB tsim, kuv yuav tsum ua qhov no ntawm dav dawb hau txij li nws tsis tau muab khoom siv. Lub zog PCB.pdf yog qhov khoob (tsis muaj cov khoom pom), powerSchematic.pdf yog rau kev tso kawm thiab lub zogSchematic2.pdf yog siv rau kev tso kawm (siv nws nrog schematic txhawm rau nrhiav cov khoom muaj nuj nqis)

Kauj Ruam 4: Luam Pawg Thawj Coj

Qhib powerPCB.pdf thiab luam tawm cov kab zauv ntawm cov ntawv ci, nco ntsoov ua kom nws zoo tshaj plaws thiab daim cartridge dub kom tau txais txiaj ntsig zoo tshaj plaws. Tom qab koj tau luam tawm cov qauv tsim, coj koj lub pcb thiab tau txais ib daim hlau ntawm cov ntaub plaub thiab ntxuav nws hauv qab dej kom txog thaum tooj liab ci, ua kom lub pcb qhuav siv cov phuam thiab tom qab ntawv kaw qhov txiav tsim lub ntsej muag tooj liab ntawm koj lub rooj tsavxwm, qhov no yuav ua kom ntseeg tau tias cov qauv tsim nyob ib puag ncig thiab tsis txav mus thaum peb tab tom hloov nws hla lub rooj tsavxwm. Tam sim no tau txais koj cov hlau, teeb nws mus txog qhov siab tshaj plaws (rau kuv nws yog hom ntaub linen) thiab pib ironing hla daim ntawv kom txog thaum nws lo rau ntawm lub rooj tsavxwm (ntev dua qhov zoo dua), tsis txhob sim tshem daim ntawv lossis koj yuav ua rau cov qauv tsim pauv thiab koj yuav tsum acetone tshem cov khoom hloov pauv thiab rov pib dua. board nrog pcb tsim thiab siv tus cim kos kho ib qho tawg los ntawm npog thaj tsam tooj liab nrog tus cim.

Kauj Ruam 5: Txheeb Pawg Thawj Coj

Sau cov yas (!!!! tsis yog hlau !!!!) ntim nrog tsuas yog tus nqi ntawm ferric chloride uas npog koj lub rooj tsavxwm, ceev faj tuav cov ferric chloride nrog ceev faj heev thiab hnav hnab looj tes roj hmab (qhov no yog cov kua qaub). koj lub rooj tsavxwm hauv kev daws teeb meem thiab pib thawb lub thawv ntim rau ib sab kom txog thaum tag nrho cov tooj liab raug tshem tawm thiab koj tau sab laug nrog cov yas xim av me ntsis xim me dua li sab nraum qab ntawm lub rooj tsavxwm (yog tias koj lub rooj tsavxwm tsis yog xim av tsuas yog xyuas kom tseeb tias tooj liab tau raug tshem tawm tag nrho los ntawm kev nthuav tawm lub rooj tsavxwm rau huab cua li 5 vib nas this, yog tias nws tig liab qab nws tseem tsis tau tshem tawm). Thaum ua tiav yaug koj lub rooj tsavxwm nrog dej thiab ntxuav tawm ib qho cim ntawm FeCl.

Kauj Ruam 6: Ntxuav Tus Tsim Tawm ntawm Pawg Thawj Coj

Tam sim no coj lub rooj tsavxwm thiab pib ntxuav tawm qhov tsim los siv ib daim paj rwb tsau rau hauv acetone, koj yuav pom nws yooj yim tshem tawm.txhua lub rooj tsavxwm thiab tom qab ntawd pib sib piv qhov tshwm sim nrog pcb tsim thiab txheeb xyuas ib qho tawg uas siv tau. cov kab thiab ntsuas kev sib txuas (qhov no tseem ceeb heev) tom qab ntawd koj tawm mus rau koj lub chaw nres tsheb drilling.

Kauj Ruam 7: Laum thiab Qhov Chaw

Tam sim no coj koj lub pcb laum thiab pib drilling koj lub rooj tsavxwm hauv qhov chaw raug, ua tib zoo siv cov khoom siv tho qhov rau txhua qhov, tsis yog tias koj tuaj yeem nthuav dav qhov ntev li koj paub tseeb tias qhov txuas txuas tseem siv tau. Tom qab ເຈາະ koj lub rooj tsavxwm, tig nws rov qab thiab pib tso cov khoom raws li qhia hauv powerSchematic.pdf, txhawm rau txheeb xyuas cov khoom siv powerSchematic2.pdf thiab sib piv nrog cov phiaj xwm qub (thov txim abt uas kuv tsuas yog tub nkeeg muab qhov txiaj ntsig tom qab 5 zaug dav dawb hau ntsia kuv schematics thiab ua tsis ncaj rau khaws cov ntaub ntawv).

Kauj Ruam 8: Cov laug

Tam sim no nrog txhua qhov khoom siv tso, coj koj cov hlau txuas thiab pib siv cov khoom sib txuas, txhawm rau ua kom huv cov laug, nqa koj cov hlau txuas thiab ua kom sov cov khoom tiv thaiv ceg tom qab ntawd siv cov xaim xaim rau ntawm txhais ceg (qhov no yuav ua rau cov kab laug sab ntws hla ob txhais ceg thiab tooj liab ncoo muab cov laug zoo thiab ntxuav ib yam nkaus) Tom qab siv koj cov khoom sib xyaw koj ua tiav:)

Kauj Ruam 9: Qee Cov Ntaub Ntawv

Tus tswj hwm no muaj cov yam ntxwv hauv qab no: 1 qhov chaw nres nkoj nkag 2 qhov chaw nres nkoj (1 rau digital voltmeter thiab lwm yam rau koj li khoom siv) kev tswj hwm los ntawm 1.2 volts mus rau 17.7 volts ntawm 12 volt input (qhov tso tawm ntau yuav sib txawv raws li qhov nkag)
