DIY lub zog-txuag teeb kho
Kev kho lub teeb txuag hluav taws xob nrog koj tus kheej txhais tes tsis yog tsuas yog ua tau, tab sis kuj tseem txhawb nqa los ntawm cov neeg siv hauv kev sib raug zoo thiab kev tshaj xov xwm. Qhov laj thawj yog yooj yim - cov tuam ntxhab ua yuam kev los ntawm kev tso cov khoom ruaj ruaj uas tuaj yeem siv sijhawm 4-5 xyoos. Txhawm rau kom nyob rau hauv kev sib tw - kom tsis txhob plam nyiaj xyoo, cov chaw tsim khoom xiam nws tus kheej cov khoom.
Yog li cas tiag? Cia peb muab tso rau hauv txee:
- Lub zog txuag hluav taws xob yog cov khoom siv hluav taws xob muaj xws li lub teeb nrog lub kauv, lub hauv paus thiab microcircuit tswj cov khoom siv fais fab.
- Cov khoom lag luam hauv qab no yog tsim tawm ntawm ntau cov nroj tsuag thiab xa mus rau cov kab kev sib dhos rau ntau lub tuam txhab. Cov lag luam kawg ua ke tsim qauv, muab lawv tus kheej logo thiab nthuav tawm cov khoom muag.
- Yog lawm Nrog qhov tshwm sim ntawm 99% ntawm cov hom teeb Pom Kev, Philips lossis tsis muaj Npe, tsis muaj qhov sib txawv. Tsuas yog tus nqi.
- Kev siv hluav taws xob kim dua ua haujlwm rau 5 xyoos lossis ntau dua, thiab cov neeg ua haujlwm pheej yig hlawv tawm hauv thawj xyoo ntawm kev pabcuam. Tsuas yog 10-30 hnub tom qab tas kev tiv thaiv.
DIY lub zog-txuag teeb kho
Qhov ua kom yuam kev hauv cov tswj nti. Ntau qhov ntsuas, nyob hauv ib qho resistor, uas raws li cov yam ntxwv tsis tau raws li cov cai teev tseg. Cov khoom siv ntawm Circuit Court tsuas yog overheats thiab hlawv tawm. Resistor 1R0 ntawm 1 Ohm, nrog tus nqi penny, yuam kom tus neeg siv pov tawm lub teeb hluav taws xob tawm thiab yuav lub tshiab.
Cov txheej txheem kev kho cov teeb meem txuag hluav taws xob yog yooj yim:
Ib txoj hlua khi tau pom ntawm lub hauv paus thiab lub qhov muag nkag, mus rau hauv ib qho uas ntsia hlau ntsia hlau loj. Yog tias tsis muaj kev txav mus los tam sim ntawd, me ntsis co lub hau ntswj, tus qauv tsim, zoo li tus menyuam roj hmab zes, qhib. Qhov khuam yuav nyob ntawm lub hau. Lub resistors ntawm lub rooj tsavxwm tau kos npe. Noj ntau qhov multimeter, nws yog qhov yooj yim kom paub tseeb tias tus sau yog qhov tseeb. Cov kws tshaj lij pom zoo siv soldering 1R2 resistor nrog lub zog ntawm 1,2 ohms. Yog tias tsis sib dhos tus qauv ua ke, lub teeb tau yooj yim xyuas los ntawm kev siv hluav taws xob.
