Indlela yokwenza laser evela DVD?

Mhlawumbi wonke umntwana afunde ubukho laser, Waphupha yawo, ekwaziyo ukunciphisa yonke indlela yayo: iinkuni, namatye nensimbi. Kakade ke, eli phupha alukhange luqokeleleke ndaweninye, kuba laser eziphakamileyo-amandla ziyingozi kakhulu kuvunyelwa ezandleni labantu ngokubanzi. Okwangoku, Noko ke, xa uphuhliso zobugcisa computer, nabani na unako ukufeza eli phupha ubuncinane ukusa kwinqanaba elithile.

I-laser lwe DVD - ifowuni iyafumaneka kubo bonke abo engafunwayo (kodwa uyasebenza) drive. Kakade ke, wamkela "ngezixhobo" ayikwazi ukwenzakalisa izinto nzima, kodwa iphepha, ikharbhodi kunye zeplastiki ize yena kakhulu okwaziyo.

Ukwenza laser evela DVD ngezandla zakhe, oko kuyimfuneko kangako: baleka (sokukhuphela efunekayo) capacitors drive umbane, iintambo zombane, ibhetri mobile phone, multimeter, a resistor, ngentsimbi ngelotha, isalathisi, isibane LED. Kakade ke, umnqweno, ixesha free kunye nezakhono ngelotha.

Ukwenza laser evela DVD-drive, kuyimfuneko ukuba ibattery kuyo. Kufuneka wakhumbula ukuba ukuze bayile ofanelekileyo ukubhala kuphela drive, ngoko abanye abanawo amandla ngokwaneleyo.

Sichitha i drive, kufuneka ukufumana kuso laser diode. Kufuneka kukhunjulwe ukuba nayiphi drive ezimbini kubo: ibenye nekumgangatho osezantsi (IR diode), omnye esinamandla (laser-obomvu). Ukwahlula phakathi kwabo kunzima, kodwa kunokwenzeka: i diode enamandla ngakumbi, nto leyo efunekayo eyimveliso laser kukuba kwi drive buyo kwaye kwiradiyetha enkulu.

Qaphela ukuba phambi kokuba kucetyiswa kokususa laser diode ukunxiba kwisihlahla nomtya, ekubeni (diode) ngala "uloyiko" kakhulu kagesi, nto leyo ulonakalise. Xa kunjalo, ukuba nesacholo ayikho kwaye akunakwenzeka ukufumana, kufuneka yisongele ubhityile kwizigqibo wire laser.

Emva kokuba umqhubi diode kufuneka solder ukususwa. Ngaphandle kwawo, i-laser lwe DVD akayi kuba nako ukufumana ukutya, kufuneka basebenze. Kuba abaqhubi zifuna yombane ezimbini capacitor 100 0.1 microfarad kunye resistor, amandla yangoku yayo ezikhethiweyo kuxhomekeke kwisantya drive (250, 300, 400, 450 no 500 Ma, ngokulandelelana, ngokuba '16x', 18x, 20x, 22x kunye 24x).

Xa ngelotha ezi zinto kunye iingcingo imveliso dibanisa kwaye thabatha kubaluleke kakhulu ukuba umva ezichaseneyo, kungenjalo laser ziya kugxagxiseka ngoko nangoko.

Ukuze amandla lesixhobo ukusebenzisa ibhetri enomphakathi yefowuni ephathwayo ukusuka 200 ukuya 300 Ma. Noko ke, kusenokuba yimfuneko kunye nobungakanani enkulu kwabanye laser.

Kwakhona njengoko umthombo wamandla ingasetyenziswa iibhetri AA.

Apha ukuze kutshekishwe ukuba umqhubi ukuba soldered ngokuchanekileyo, kufuneka ukudibanisa ku yesibini (amandla) diode idrayivu, yaye kunye multimeter ukulinganisa inqaba yangoku.

Ukuba yenziwe ngendlela eyiyo, ungenza ekugqibeleni kuthatha laser evela DVD kunye wasibeka izindlu oyifunayo. Ukuba ifowuni ukuba athathe ixesha elide, kucetyiswa ukuba ukulungisa zonke izinto endaweni kulu bazitywine.

Yenza laser lwe DVD elula ngokwaneleyo, kodwa xa usebenza naye ukuba silumke. Kufuneka kukhunjulwe ukuba ingabangela umonakalo, ngoko ke asikwazi ingabhekiswa ngqo isilwanyana okanye abantu. Iliso laser kungakhokelela ukwehla baphulukane umbono.
