Yog tias koj lub tshuab txais hluav taws xob, cov neeg ua si lossis lub koob yees duab khiav ntawm lub roj teeb, sim hloov lawv nrog roj teeb rov qab. Tsis zoo li roj teeb, lawv tuaj yeem tau them rov qab ntau zaus. Txawm nyob hauv ib xyoos, txoj kev no koj tuaj yeem txuag tau ob mus rau peb txhiab rubles.
Cov Lus Qhia
Kauj ruam 1
Txwv tsis txhob sim them cov roj teeb uas tsis tsim rau qhov no los ntawm ib txoj kev. Nco ntsoov them lithium-ion, lithium-polymer thiab lithium-hlau roj teeb tsuas yog siv nrog cov khoom tsim Hoobkas. Ua koj lub chargers rau NiCd thiab NiMH cov tshuab hluav taws xob.
Kauj ruam 2
Xam cov nuj nqis tam sim no rau ib qho roj teeb. Ua li no, faib nws lub peev xwm ntawm kaum. Yog tias muaj peev xwm nyob hauv milliampere-teev, qhov them nyiaj tam sim no yog hauv milliamperes.
Kauj ruam 3
Siv lub zog siv hluav taws xob kom nws cov khoom siv hluav taws xob tsawg yog tsawg kawg plaub qhov hluav taws xob siab dua li cov xaim hluav taws xob ntawm lub roj teeb, thiab cov thauj khoom tam sim no ntau tshaj qhov tawm ntawm cov kev them nqi tam sim no ntawm txhua lub roj teeb (lawv yuav raug them sib cais kom txo kev coj).
Kauj ruam 4
Yuav khoom ntau LM317T voltage tswj hwm raws li lub roj teeb yuav them rau tib lub sijhawm.
Kauj ruam 5
Thov nco ntsoov tias, txawm hais tias qhov zoo sib xws, LM317T stabilizer sib txawv hauv pinout los ntawm cov paub zoo stabilizers 7805, 7809 thiab zoo sib xws. Uas yog, thawj qhov tawm los ntawm nws yog kev hloov kho, qhov thib ob yog tsim tawm, thiab qhov thib peb yog kev tawm tswv yim.
Kauj ruam 6
Txhawm rau kom LM317T microcircuit pib pib tswj lub zog tam sim no es tsis txhob siv hluav taws xob, mus rau kev ua kom yuam kev. Ua ntej tshaj, txo nws cov hluav taws xob tawm mus rau qhov tsawg kawg nkaus. Txhawm rau ua qhov no, siv cov kev tswj qhov tso tawm ntawm tus stabilizer uas muaj ntau dua, ua ib yam nkaus li tau ua thaum siv cov stabilizers. Qhov hluav taws xob tso tawm yuav muab sib npaug rau 1.25 V. Qhov ob, txuas lub nra rau nws cov zis tawm, kom ntawm 1.25 V nws noj tam sim no sib npaug rau them tam sim no ntawm ib lub roj teeb. Los xam nws qhov kev tawm tsam, siv faib tus lej 1.25 los ntawm tus nqi them tam sim no, qhia hauv milliamperes. Kev tawm tsam yuav nyob hauv kilo-ohms. Lub zog uas yuav muab faib rau lub nra, txiav txim siab los ntawm sib tshooj tus lej 1.25 los ntawm tam sim no. Nws yuav qhia hauv milliwatts.
Kauj Ruam 7
Thov nco ntsoov tias tus tswj txoj cai siv tam sim no yog tsawg heev. Yog li ntawd, qhov tam sim no uas nws noj ntawm lub tswv yim yuav raug xyaum sib luag nrog cov ntsaws tam sim no. Siv cov cuab yeej no los tswj kho qhov tam sim no los ntawm cov roj teeb. Txhawm rau ua qhov no, txuas lub tswv yim ntawm tus stabilizer mus rau lub zog siv los ntawm lub roj teeb, soj ntsuam cov polarity (ntxiv rau ntawm lub hauv paus rau ntxiv rau lub roj teeb, rho tawm cov roj teeb rau cov tswv yim ntawm tus stabilizer, cov hlau ntau ntawm cov stabilizer rau qhov rho tawm ntawm lub hwj chim mov).
Kauj ruam 8
Sau cov khoom siv khov kho kom ntau raws li muaj roj teeb. Muab txhua lub microcircuits rau cov kuab cua sov cais uas tsis txuas nrog hluav taws xob sib txuas. Txo cov khoom nkag thiab tawm ntawm microcircuits nrog oxide thiab ceramic capacitors ntawm lub peev xwm me me. Txuas cov oxide capacitors nrog polarity. Lawv qhov voltage khiav hauj lwm yuav tsum muaj tsawg kawg yog 10 V.
Kauj Ruam 9
Tig lub hwj chim rau lub charger, thiab tom qab 15 teev, tua thiab tshem lub roj teeb uas raug them.
