Koj yuav xav tau txoj haujlwm no thaum koj muaj lub roj teeb txawb ntxiv lossis koj xav tau them ib lub roj teeb, Lithium ion lossis Lithium Polymer roj teeb.
Qhov siab tshaj tam sim no yog li 650 milliamps. Lub Circuit Court tau tsim los rau roj teeb ntawm 900mah lossis siab dua. Lub zog hluav taws xob tuaj yeem yog 12v Gell cell (Lub vaj huam sib luag), lossis tuaj yeem siv tau los ntawm lub tsheb luam yeeb. Kuv siv lub qub 12v DC phab ntsa hloov pauv (800ma lossis ntau dua.)
Kauj ruam 1: Schematic
Circuit Court yog qhov yooj yim, koj yuav xav tau cov hauv qab no
LM317 tus tswj hwm sib txawv 2N2222A lossis ib qho Transistor ua haujlwm 800mA 2 Capacitors 0.1 uf 1K POT 1ohm 1Watt resistor (tus txwv tam sim no) Kho R4 rau qhov xav tau qhov hluav taws xob R1 tswj cov zis tam sim no
Kauj Ruam 2: PCB
Nov yog PCB ntawm txoj haujlwm, kuv tau siv "Toner Transfer" txoj kev, nws muaj zog heev
thiab yooj yim. Siv HP Glossy ntawv thiab Laser tshuab luam ntawv muab cov txiaj ntsig zoo
Kauj Ruam 3: Kauj Ruam Kawg
Txoj haujlwm tiav tom qab siv cov khoom sib txuas
Kuv tau siv lub dab dej kub me me rau LM317 thaum them lub roj teeb loj dua.
