Lub laser ntawm cov DVD tsav nrog koj ob txhais tes

Muaj ntau ib tug me nyuam twb laser pointers uas yuav tau muas ntawm qho khoom ua si khw muag khoom noj. Tab sis, nrog txoj kev loj hlob ntawm niaj hnub technologies lub sij hawm los mus tsim xws li ib tug laser los ntawm ib tug DVD tsav nrog koj ob txhais tes. Koj yuav tsum tau tsuas yog ib tug faulty DVD tsav (nws yog ib qho tseem ceeb hais tias nws tseem serviceable LED), ib tug ntswj ntsia hlau thiab ib tug soldering hlau.

Nws yuav tsum tau nco ntsoov tias laser yog qhov zoo tshaj plaws los mus siv ib tug uas tsis yog-ua hauj lwm DVD! Qhov no yog vim lub fact tias tom qab dismantling thiab rov qab los ntawm cov LED nws crashes. Tsis txhob hnov qab hais tias xws li ib tug laser ntawm tus tsav yog muaj zog tshaj li qub pointers thiab yuav ua rau kom muaj teeb meem, thiaj tsis yuav tsum coj tus nqaj rau tib neeg los yog tsiaj. Hovering beam ntawm lub ntaus ntawv rau ib tug tib neeg qhov muag retina burning tshwm sim, thiab tus neeg uas muaj peev xwm tej los yog kiag li tsis tau pom.

Yog li ntawd, cia peb ua ib tug laser los ntawm ib tug DVD tsav nrog koj ob txhais tes. Ua li no, ua tib zoo unscrew lub bolts rau lub tsheb ntawm cov ntaub ntawv tau mus rau lub neej yav tom ntej ntawm lub LED laser. Nyob rau hauv lub hood yog lub ntawm uas ua lub carriage tsav. Nyob rau hauv thiaj li yuav extract nws, koj yuav tau unscrew lub screws thiab disconnect tag nrho cov cables. Ces tus carriage yog muab tshem tawm.

Tam sim no nws yog tsim nyog los lauj nws rau dab tsi unscrew heev heev screws. Tom ntej no, lub ob LEDs nrhiav. Ib tug yog infrared, nws yog lub luag hauj lwm rau kev nyeem ntawv ntaub ntawv los ntawm lub disk. Xav liab, uas yog hlawv cov ntaub ntawv rau disc. luam Circuit Court board yog txuas mus rau lub liab LED. Lov tes taw nws, koj yuav tsum siv ib tug soldering hlau. Mus xyuas lub efficiency ntawm lub diode yog txaus mus cuag nws ob tug penlight roj teeb, tab sis nws yog ib qho tseem ceeb coj mus rau hauv tus account lawv polarity. Nco ntsoov hais tias lub laser diode yog lub cev tsis kho, ces nws yog tsim nyog yuav tsum tau ceev faj heev.

Tom ntej no koj yuav tau yuav tej laser pointer. Tsim ib tug laser los ntawm ib tug DVD tsav nrog koj ob txhais tes, siv nws li ib tug "pub" vaj tse nyob. Tom qab lub purchase yog tsim nyog los ua tib zoo untwist pointer nyob rau hauv ob thiab tshem tawm cov sab sauv ib nrab ntawm cov laser diode. Koj siv tau ib rab riam. Nws yog ib qho tseem ceeb ua txhua yam kom zoo, vim hais tias nws yuav ua kev puas lub diode. Los ntawm txhais tau tias ntawm ib tug me me ntswj ntsia hlau xaiv emitter. Siv kub yaj teev ib tug tshiab LED nyob rau hauv lub vaj tse. Thiab yog li ntawd nws yog zoo tsim, koj muaj peev xwm siv pliers, nias lawv nyob rau hauv lub ntug ntawm lub diode.

Lub laser ntawm cov DVD tsav nrog koj txhais tes yog yuav luag npaj txhij. Ua ntej koj yuav khiav nws, koj yuav tsum xyuas seb lub determined polarity yog muaj tseeb. Tam sim no koj tau yam xyuam xim txuas lub hwj chim. Tom qab thawj pib kom pom tseeb hloov tej zaum yuav tsum tau. Ces koj yuav tau teem lub pointer rau hauv ib lub teeb khoo thiab nuv AA roj teeb. Tsis txhob hnov qab tias cov laser muaj peev xwm hlawv ib tug ntau yam ntawm tej yam khoom, yog li ntawd koj yuav tsum tshem tawm cov plexiglass ntawm lub diffuser.

Ib tug zoo-tuned laser ntawm cov DVD tsav yuav tsis tau tsuas yog hlawv ntawv los yog zes qhov yuam kev, tab sis kuj yuav tawm ib tug kab nyob rau hauv plexiglass, tshuab khoom (zoo dua yog hais tias lawv twb dub) thiab tawm pom tias nyob rau hauv lub hnab yas. Yog hais tias koj siv ib tug diode nyob rau hauv lub taub hau ntawm ib tug plotter, koj yuav ua li cas engraving rau Plexiglas.
