Los ntawm telec16 Ua raws ntau ntxiv los ntawm tus sau:
Freeform circuits, lossis kab laum tuag, lossis cov ntsiab lus-rau-taw tes tsim yog txoj hauv kev zoo los pib ua qauv tsis tas ua PCB, thiab hloov pauv tau ntau dua li kab txaij/perfboard!
Kuv nquag siv cov txheej txheem no rau cov haujlwm me me lossis txhawm rau daws qhov loj dua. Tab sis lwm qhov txias tshaj plaws ntawm daim ntawv pub dawb yog tias lawv saib zoo! Koj tuaj yeem ua si nrog cov khoom siv thiab cov xov hlau hauv 3D, tsim ntau yam sib txawv, ntau dua li nrog PCB yooj yim.
Hauv cov lus qhia no kuv yuav qhia koj yuav ua li cas kom tsob ntoo Christmas ntsais muag, thiab qhia koj txog kev pib ua qauv dawb.
Khoom siv
Koj yuav xav tau qhov no:
- Tooj hlau (Kuv siv 2 hli tooj dag hlau, thiab nws loj me me, tab sis cov tooj liab tooj liab zoo li zoo)
- Cheebtsam rau koj lub voj voog!
Thiab cov cuab yeej no:
- Ib qho hlau txuas
- Nyias pliers
- Cov xov hlau me me
Kauj ruam 1: Circuit Court
Lub voj voog no tuaj yeem sib cais ua peb ntu: oscillator, inverter, thiab LEDs.
Tus oscillator tau ua nyob ib puag ncig ntawm tus paub NE555, Kuv tau suav qhov tseem ceeb ntawm tus tiv thaiv thiab lub ntsuas hluav taws xob siv qhov muaj txiaj ntsig zoo hauv app: ElectroDroid.
Yog lawm, tam sim no peb muaj lub teeb ntsais ntsais, peb yuav tsum nrhiav txoj hauv kev los ua kom lub zog LEDs hla dhau tsuas yog ob lub xov hlau (ob ntu ntawm tsob ntoo). Peb tuaj yeem xaiv los teeb lawv txhua tus hauv kev sib cuag, tab sis qhov ntawd yuav zoo dua los ntsais muag lawv, tsis yog? Raws li LEDs tsuas yog teeb pom kev zoo hla lawv, peb tuaj yeem ua ob pawg hauv kev tawm tsam thiab tsim qhov hloov pauv qhov zoo/qhov tsis zoo hla lawv.
Txhawm rau ua qhov ntawd, peb yuav xav tau lub qhov rooj tsis yog, ua nrog ob lub transistors hauv Push-Pull teeb tsa.
Kauj Ruam 2: Yuav Khoov Ntoo Li Cas
Pib los ntawm kev kos duab ntawm tsob ntoo, thiab tom qab ntawd khoov cov xaim tooj liab nrog nws, siv daim kab xev nyias.
Thaum koj tau ua thawj ntu, khoov thib ob, ua raws thawj zaug, kom lawv zoo ib yam.
Kauj Ruam 3: Soldering - Blinker
Kuv pib los ntawm kev siv lub 555 thiab tag nrho nws cov khoom siv los ua kom nws oscillating. Kuv tau siv ob txoj hlua tooj liab ntev thiab tuab rau cov kab hluav taws xob, uas tseem ua haujlwm sawv ntsug.
Kauj Ruam 4: Soldering - Tsob Ntoo
Tom qab ntawd koj tuaj yeem txuas ib ceg ntawm ib feem ntawm tsob ntoo mus rau tus pin 3 (tso tawm) ntawm 555. Tom qab ntawd, muab tso rau qhov chaw thib ob ntawm tsob ntoo, thiab tuav nws los ntawm kev siv qee cov LEDs nruab nrab ntawm nws thiab thawj ntu.
Kauj Ruam 5: Soldering - Lub Qhov Rooj Tsis
Nws yuav luag tiav! Tsuas yog ntxiv qhov rooj tsis nyob nruab nrab ntawm ib ceg ntawm tsob ntoo thiab lwm yam.
Kauj Ruam 6: Khoov Lub Roj Teeb
Tom qab ntawd khoov ob lub xov tooj hluav taws xob kom koj tuaj yeem tso tsawg kawg yog ob lub npib ntawm cov roj teeb (6V, koj tuaj yeem mus txog 5 lub roj teeb, lossis 15V). Saib xyuas qhov polarity!
Txij ntawm no mus, LEDs yuav tsum ntsais muag.
Kauj ruam 7: Txaus siab rau
Solder qee qhov LEDs ntxiv ntawm ob ntu ntawm tsob ntoo, thiab nws tau ua tiav!
