Ukukhempa ngaphandle kuyindlela ethandwa kakhulu yeholide manje. Ngake ngaphupha ngokuhambahamba emhlabeni wonke ngenkemba yami futhi ngikhululeke futhi ngijabule. Manje ngifuna nje ukubalekela umjikelezo wokuphila omatasa. Nginabangane abathathu noma abahlanu, intaba nesibani esingenamuntu, ebusuku obukhulu obugcwele izinkanyezi. Zindla ngenhlamba yangempela...Funda kabanzi -
Indlela yokushaja isibani sekhanda
Ithoshi ngokwalo lisetshenziswa njalo empilweni yethu yansuku zonke, ikakhulukazi isibani sangaphambili, esisetshenziswa kabanzi ezinhlelweni eziningi. Isibani sangaphambili esifakwe ekhanda kulula ukusisebenzisa futhi sikhulula izandla ukuthi zenze izinto eziningi. Indlela yokushaja isibani sangaphambili, ngakho-ke sikhetha Uma uthenga isibani sangaphambili esihle,...Funda kabanzi -
Yiziphi izidingo zokushisa kombala wezibani zengadi ze-LED?
Ezindaweni zokuhlala, kuzofakwa izibani ze-LED ezingamamitha amathathu kuya kwamane emigwaqweni yezinyawo nasezingadini ezindaweni zokuhlala. Manje cishe sonke sisebenzisa imithombo yokukhanya ye-LED njengemithombo yokukhanya yezibani zengadi ezindaweni zokuhlala, ngakho-ke yimuphi umthombo wokukhanya wokushisa kombala okufanele usetshenziswe...Funda kabanzi -
