Kodi kupanga laser kuchokera DVD?

Mwina onse mwana kuphunzira za kukhalako kwa laser, anayamba loto la zawo, angathe kudula zonse mu njira yake: nkhuni, miyala ndi zitsulo. Kumene, maloto sanathe anazindikira, chifukwa lasers mkulu-mphamvu ndi oopsa kwambiri kuloledwa m'manja a anthu onse. Panopa Komabe, pamene chitukuko cha makompyuta, aliyense akhoza kukwaniritsa maloto osachepera kumlingo.

The laser a DVD - chipangizo ulipo kwa onse amene ali osafunika (koma kugwira) pagalimoto. Kumene, analandira "zida" sangativulaze zipangizo zovuta, koma pepala, zikatoni ndi pulasitiki ngakhale iye amatha ndithu.

Kupanga laser kuchokera DVD ndi manja ake, m'pofunika osati mochuluka: akuthamanga (chofunika burner) pagalimoto voteji capacitors, Kulumikizana, batire foni, multimeter, ndi resistor, chitsulo soldering, Cholozera, LED tochi. Ndipo, ndithudi, kukhumba, nthawi ufulu ndi luso soldering.

Kupanga laser kuchokera DVD galimoto, m'pofunika disassemble izo. Iwo ayenera kukumbukira kuti mapulani abwino okha kulemba galimoto, kotero anthu ena alibe mphamvu zokwanira.

Dismantling ya galimoto, muyenera kupeza mmenemo ndi laser diode. Kumbukirani kuti mu galimoto iliyonse awiri a iwo wofooka (IR diode), wina kwabasi (laser-wofiira). Kusiyanitsa pakati pa iwo ndi zovuta, koma n'zotheka kuti: diode wamphamvu kwambiri, zomwe zingamuthandize kupanga laser ali mu ophimba pagalimoto ndipo ali Redieta zikuluzikulu.

Onani kuti pamaso kuchotsa laser diode tikulimbikitsidwa kuvala dzanja kachingwe, popeza (diode) kwambiri "mantha" magetsi malo amodzi, amene angathe kuwononga izo. Zikatero, ngati chibangili si ndipo n'kosatheka kuti, muyenera kukulunga woonda waya laser tanthauzo lake.

Pambuyo dalaivala diode ayenera solder kuchotsa. Popanda izo, laser ya DVD sadzatha kupeza chakudya, muyenera ntchito. Madalaivala amafuna voltages awiri a capacitor 100 0.1 microfarad ndi resistor, mphamvu panopa chimene anasankha malingana ndi changu pagalimoto (250, 300, 400, 450 ndi 500 MA, motero, chifukwa 16x, 18x, 20x, 22x ndi 24x).

Pamene soldering zinthu izi ndi mawaya linanena bungwe kwa kuphatikiza ndi opanda Nkofunika kuti kusintha polarity, mwinamwake ndi laser adzakhala poipa yomweyo.

Zopangira chipangizo angagwiritse ntchito batire la mphamvu foni kuchokera 200 mpaka 300 MA. Komabe, kungakhale kofunika ndi mphamvu zazikulu chifukwa ena lasers.

Komanso ngati mphamvu gwero angagwiritsidwe ntchito AA mabatire.

Pofuna kufufuza ngati dalaivala ali soldered molondola, muyenera kugwirizana kwa wachiwiri (ofooka) diode a galimoto, ndi multimeter ndi kuyeza mphamvu ya pano.

Ngati mwachita bwino, mukhoza potsiriza kusonkhanitsa laser kuchokera DVD ndi kuuika mu nyumba ankafuna. Pakuti chipangizo yayitali, Ndi bwino kukonza zinthu zonse mu malo ndi zomatira ndi kuwasindikizira iwo.

Kodi laser a DVD ndi losavuta mokwanira, koma pamene wogwira naye ntchito kusamala. Kumbukirani kuti kungawononge, choncho simungathe kupita kwa nyama kapena a munthu. Diso laser kungachititse kuti kuwonongeka ndipo ngakhale imfa ya masomphenya.
