Txuas cov xaim usb mus rau qhov taw qhia dhau los ntawm 10 ohm resistor ces siv 1n 4007 diode thiab txuas rau cov xov hlau zoo ntawm usb ces txuas ob qho tib si zoo thiab tsis zoo xaim mus rau roj teeb cov kauj ruam tom ntej yog txuas lub roj teeb zoo rau hloov thiab roj teeb tsis zoo rau 1ohm resistor ces txuas qhov ntawd mus xaim rau coj vaj huam sib luag. Cov xov hluav taws xob tau ua tiav tiav. Siv daim ntawv yas txuas rau sab saum toj ntawm lub npov thiab muab daim iav coj los rau sab saum toj ntawm daim ntawv
