Video: DIY Force Sensitive Resistor (FSR): 5 Kauj Ruam (nrog Duab)
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31
Ua kom lub zog tiv taus tiv taus (lub ntsuas siab) nrog cov khoom seem tsis siv $ 5 - $ 20 txhua.
Kauj ruam 1: Cov ntaub ntawv
Cov cuab yeej
- Soldering hlau
- Kub kua nplaum phom
- Riam/rab chais
- Hlau txiav
Cheebtsam
- Solder
- Kub kua nplaum
- Ib-tog tooj liab PCB
- Ua npuas ncauj
- Hlau
Ua npuas ncauj
Yog tias koj tau txais me me ATmega microcontrollers lossis PICs, qee zaum lawv yuav nyob ib puag ncig los ntawm cov khoom ua npuas hauv me me lossis lub thawv. Tsis yog txhua qhov ua npuas dej tau tsim muaj vaj huam sib luag: qee qhov nws thaws rov qab mus rau qhov zoo dua lwm tus. Yog tias koj siv PIC ua npuas dej los ua koj li FSR, nws yuav teb sai, tab sis yog tias koj siv ATmega ua npuas ncauj yuav siv sijhawm thib ob los tso. Qhov tseeb tias FSR no muaj qhov pom tsis tau yog qhov sib txawv ntawm lwm FSRs.
Kauj ruam 2: Sizing
Siv rab riam/rab chais kom tau qhab nia koj li PCB rau hauv ob daim phiaj uas tsom iav ib leeg. Kuv mus nrog kwv yees li ib-square-inch squares, tab sis koj tuaj yeem ua ob daim duab ntev li ntev tau muaj tooj liab nyob nruab nrab.
Txiav koj ua npuas dej rau hauv cov duab zoo ib yam li lub phaj. Muab ib txoj hlua xaim rau txhua phaj. Koj yuav xav paub tseeb tias tus laug yuav tuav cov hlau nyob hauv qhov chaw, yog li ntxuav tooj liab ua ntej yog tias tsim nyog thiab siv cov laug ntau.
Kauj Ruam 3: Txuas Cov Ntawv
Kuaj peb daim ua ke. Tsuas yog lo raws tus qauv ntawm FSR, txwv tsis pub nws yuav ua tsis tau zoo. Rau kuv tus kheej, Kuv tsuas yog lo rau sab saum toj thiab hauv qab ntawm ob daim hlau rau ua npuas ncauj.
Kauj Ruam 4: Xeem Nws
Lob tus multimeter thiab ntsuas qhov tsis kam hla koj li FSR. Koj qhov txiaj ntsig yuav txawv, tab sis kuv tau txais txog 200 kiloohms ntawm so thiab 9 kiloohms thaum yuav luag tag kev nyuaj siab. Yog tias koj cov phaj muaj thaj tsam loj dua, lossis ua npuas dej nyob nruab nrab yog qhov me dua, cov txiaj ntsig no yuav me dua.
Kauj ruam 5: Sau ntawv
Variations
- Siv nws Dim Dim LED (yees duab + chaws)
- Siv nws los ua suab nrov (yees duab)
- Sim ua ntau hom ua npuas dej (kuaj tsis kam hla ua npuas dej ua ntej kom ntseeg tau tias nws muaj kev coj ua)
- Txiav cov duab txawv txawv
- Kuaj cov txheej txheem ua npuas dej sib txawv (piv txwv li: ua npuas ntau txheej)
- Kuaj cov phaj sib txawv (piv txwv li: txhuas ntawv ci ntawm cov duab los qhia/yas/ntoo)
- Ua humongous FSR arrays
