Nyob zoo txhua tus! Hauv cov lus qhia no kuv yuav qhia koj yuav ua li cas ua piano me me siv Timer ntau 555 tab sis nrog cov khoom SMD
SMD txhais tau hais tias Surface-Mount Device thiab cov khoom siv tau teeb tsa lossis tso ncaj qha mus rau saum npoo ntawm cov laug cam luam tawm
Cia peb pib
Kauj Ruam 1: Kauj Ruam 1: Qhov Chaw thiab Cov Cuab Yeej
Qhov zoo ntawm SMD cov khoom yog tias lawv pheej yig heev thiab lawv tuaj hauv ntau qhov yog li koj yuav muaj cov khoom lag luam rau lwm zaus koj xav tau!
Qhov:
1x SMD 555 Timer (Aliexpress:
8x SMD hloov khawm (Aliexpress:
8x 1K 0805 SMD resistors (Aliexpress:
1x 10K SMD potentiometer (Aliexpress:
1x SMD 0.1uF SMD capacitor (Aliexpress:
1x SMD 10uF SMD capacitor (Aliexpress:
1x Mini hais lus (koj tseem tuaj yeem siv lub suab nrov tab sis lub hom phiaj yog ua kom nws me me!)
(Aliexpress:
1x 9V roj teeb clip (Aliexpress:
Cov tooj liab tooj liab PCB (saib cov ntsuas thiab cov ntaub ntawv Eagle hauv qab no).
Cov Cuab Yeej:
Soldering hlau
Solder
Etching tov thiab toner hloov daim ntawv los ua lub rooj tsavxwm.
Kauj Ruam 2: Kauj Ruam 2: Ua Lub Rooj Tsav Xwm
Txhawm rau ua lub rooj tsavxwm no kuv tau siv txoj kev hloov pauv toner. Ntawm no koj muaj cov ntaub ntawv dav dawb hau. Koj tsuas yog yuav tsum luam nws daim iav.
Ua ntej peb yuav tsum txiav ib daim txiag ntoo. Kuv qhov ntev yog 5, 8cm x 3, 1cm.
Koj yuav tsum paub tseeb tias koj lub tshuab luam ntawv yog LASER ib qho kom txoj hauv kev no ua haujlwm. Tom qab ntxuav lub rooj tsavxwm nrog cawv, kuv ironed daim ntawv rau hauv pawg thawj coj saib tooj liab. Ua kom sov, cov hlau ib txwm yuav ua tau zoo, li ntawm 10-15 feeb. Tsiv cov hlau thiab thawb lub zog kom hloov lub Circuit Court. Feem ntau, nws yuav tsis muaj teeb meem tab sis kuv ua nws zoo li no tsuas yog kom ntseeg tau.
Tom qab qhov no, cia lub rooj tsavxwm txias thiab tom qab ntawd pib tev daim ntawv ua tib zoo. Nws yuav tawm los yooj yim heev thiab… voilà, peb muaj peb lub rooj tsav xwm luam tawm.
Etching
Kuv txheeb cov laug cam nrog 50% sib xyaw hydrogen peroxide thiab hydrochloric acid. Cia nws nyob ob peb feeb kom txog thaum tooj liab ploj thiab tom qab ntawd, tsau lub rooj tsavxwm hauv dej kom ntxuav cov tshuaj tov.
Tam sim no peb yuav tsum tshem tus number case. Koj tuaj yeem siv cawv thiab ntaub plaub plaub thiab tom qab txhuam nws tus number case yuav tsum tawm yooj yim.
Nco ntsoov xyuas ob zaug tias tsis muaj cov kab hluav taws xob luv ntawm cov ciav hlau, yog tias muaj, txiav txoj kev kov nrog kev pab ntawm rab riam ntse.
Thiab qhov ntawd yog, tam sim no peb muaj pawg thawj coj npaj los tso cov khoom!
Kauj Ruam 3: Kauj Ruam 3: Soldering
Ua ntej tshaj plaws, peb tab tom yuav pib ua cov laug khawm. Qhov tseeb, koj tuaj yeem siv txhua yam uas koj xav tau hauv thawj qhov chaw vim tias tsis muaj ntau qhov, tsis muaj ib qho ntawm lawv yuav cuam tshuam peb thaum peb muag lwm tus.
Nov yog kuv txoj kev tab sis koj tuaj yeem muaj koj tus kheej!
Ua raws li daim duab kom yaj cov nyees khawm.
Tom qab ntawd peb tuaj yeem txuas tus 1K resistors. Muaj 7 ntawm lawv nyob rau sab saum toj ntawm cov nyees khawm.
Tom qab ntawd, muab lub 555 Timer tso rau hauv nws qhov chaw. Kuv tsis tshua muaj txoj hauv kev los txhawm rau SMD ICs Kuv tsuas yog siv lawv txhais taw los ntawm txhais ceg nrog ua siab ntev ntau!
Tam sim no peb tuaj yeem siv lub tshuab hluav taws xob. Kuv yuav tsum lees tias qhov no nyuaj me ntsis tab sis ntxiv, nrog ua siab ntev, txhua yam tuaj yeem ua tiav. Nrog lub zog no peb tuaj yeem hloov kho lub suab kom ua suab zoo li piano tiag.
Koj yuav pom tias muaj 1K resistor sab laug. Nws mus ib sab ntawm lub zog, ntsuas nws!
Peb yuav luag tiav! Peb muaj 2 lub capacitors sab laug. Txheeb xyuas cov duab kom paub qhov twg los muab lawv tso!
Tam sim no, tus hais lus (lossis lub suab nrov), vim tias lawv tsis muaj qhov sib txawv, peb tuaj yeem muab lawv tso rau hauv txhua txoj haujlwm. Tsuas yog muab nws tso rau hauv nws txoj haujlwm.
Thiab thaum kawg, tab sis tsis tsawg kawg qhov tseem ceeb, lub roj teeb clip. Txiav nws mus rau qhov ntev uas tsim nyog thiab muab tshuaj txhuam nws!
Tam sim no peb tau ua tiav peb cov SMD piano!
Kauj Ruam 4: Kauj Ruam 4: Xaus
Tam sim no, peb tsuas xav tau ntsaws peb lub roj teeb 9V thiab pib ua si qee cov nkauj zoo!
Tej zaum koj yuav yog Mozart tom ntej! Leej twg paub!
Kuv vam tias koj nyiam cov lus qhia no! Qhov piano me me no yog lub tswv yim zoo rau khoom plig vim tias me me thiab pheej yig heev!
Vam tias koj muaj kev lom zem ntau dua li nws tau raws li kuv tau sau txhua yam qhia no rau koj!
Thiab, yog tias koj nyiam nws, tsis txhob hnov qab pov npav rau kuv hauv Kev Sib Tw Ncaws Pob!
Pom koj nyob rau lwm qhov!
