Koj tau xyaum ua ntev ntev los ua tus npauj npaim zoo yav tom ntej. Cia li xav txog ntau npaum li cas glances koj yuav twv yuav raug hu nyiam thaum koj ntxiv lub teeb nyhuv rau koj kev ua kom yuam kev.
Nws yog qhov tsim nyog
- Skates;
- LED Sawb Teeb;
- cable;
- 2 khawm;
- cov tuav roj teeb;
- roj teeb;
- clamps thiab daim kab xev hu rau kom paub tseeb cov roj teeb;
- cov nplaum pleev xim;
- ham;
- soldering acid;
- soldering hlau;
- txiab;
- ntawv sau riam.
Cov Lus Qhia
Kauj ruam 1
Kuaj xyuas koj cov skates rau qhov chaw sau dawb kom thiaj li ua tiav nrog cov LEDs, lub hwj huam xa tawm, thiab lwm yam khoom siv hluav taws xob
Kauj ruam 2
Tom qab txiav txim siab tag nrho cov kev ntsuas tsim nyog, npaj cov ntu hauv qab no uas koj yuav tsum tau sib sau ua ke ob tus qauv rau cov khoom siv: 8 lub teeb ci super ci (hluav taws xob lub teeb ci ci 120 degrees), 2 SMD 1206 jumpers, 0 Ohm, 4 SMD 0805 resistors, 4.7 * Ohm, 2 chokes SMD 1206, 3.3 * μH, 2 diodes BAT54 (tsis muaj ntawv), 2 tantalum capacitors SMD A, 1 μF, 2 tus tsav tsheb ZXLD381 thiab 2 lub roj teeb ua ke.
Kauj ruam 3
Sib sau ua ke cov hluav taws xob hluav taws xob uas pom hauv daim duab hauv qab no. Xaiv cov teeb ci ntawm cov LED uas koj xav tau. Txhawm rau ua qhov no, hloov qhov inductance ntawm txhawm chim. Yog tias qhov inductance siab dua, ces qhov muab cov khoom siv yuav tsawg dua raws li cov ntaub ntawv sau tseg. Yog tias qhov sib txawv ntawm qhov ci ci ntawm qhov ci ci yog loj dhau, tom qab ntawd hloov kho nws los ntawm kev hloov pauv ntawm kev tawm tsam hauv Circuit Court.
Kauj ruam 4
Muag txhua feem ruaj khov rau hauv ib lub Circuit Court, txhim kho lawv rau ntawm daim txiag. Xav txog tej yam thiab ua qee yam rooj plaub rau cov qauv. Siv cov khaub-ncaws nyias me me rau qhov no.
Kauj ruam 5
Muab lub cuab yeej txuas rau hauv qab ntawm daim tiab hauv thaj tsam ntawm qhov chaw tuav. Muab LEDs rau sab laug thiab sab npoo ntawm pawg thawj coj. Qhov no yog li kom lawv tusyees ci ntsa iab rau thaj chaw hauv qab khib ntawm txhua sab. Muab lub hwj huam tso rau hauv nruab nrab kom cov roj teeb sib txuas ncaj qha nyob hauv qab pliav. Siv roj av AA lossis AAA rau cov khoom siv fais fab, nyob ntawm qhov loj thiab thaj chaw ntawm koj lub cuab yeej.
Kauj Ruam 6
Koj tseem tuaj yeem ua ke sib pauv mus qhib thiab kaw lub Circuit Court kom koj tuaj yeem qhib thiab kaw lub teeb ntawm koj lub skates txhua lub sijhawm. Txawm li cas los xij, qhov no tsis tsim nyog tshwj xeeb, xws li thaum caij tsheb, koj yuav tsis tshua xav tua lub backlight.
