Ulawulo lwe-Universal Remote (4 ngo-1)

Icala loku-1: onke amaqhosha akude akasebenzi.

Uhlalutyo kunye nokugcinwa: uninzi lwezizathu zokuba kutheni zonke izitshixo zesilawuli kude zingasebenzi zibangelwa ngumonakalo wecrystal oscillator. Ukuba uwe okanye ujonge unomathotholo ukuba akukho sandi "sebeep", unokutshintsha ngokuthe ngqo ngekristal oscillator. Emva kokufakwa kwe-oscillator yekristale entsha, ukuba isiphoso asinakupheliswa, ombane kumacala omabini e-crystal oscillator kufuneka alinganiswe kuqala. Xa naliphi na iqhosha licinezelwe, kuyakubakho utshintsho olucacileyo lombane kuzo zombini iziphelo ze-crystal oscillator, ebonisa ukuba i-oscillator inokuvelisa uphawu lwe-pulse. Okwesibini kukujonga ukuba ngaba lukhona utshintsho kumandla ombane abuthathaka kwisiphelo solawulo lwerimowuthi yebhloko ehlanganisiweyo. Ukuba kukho utshintsho, jonga ukuba ngaba i-triode yokuqhuba kunye ne-infrared transmit tube zonakele. Ngaphandle koko, uninzi lweebhloko ezihlanganisiweyo zinesiphene.

Icala 2: amanye amaqhosha awasebenzi.

Uhlalutyo kunye nokugcinwa: le nto ibonakalisa ukuba ulawulo lwerhafu luqhelekile xa lulonke, kwaye isizathu sokuba ezinye izitshixo zingasebenzi kukuba unxibelelwano lwesekethe engundoqo alunakuqhuba ngokufanelekileyo. Uninzi lwabafowunelwa kwibhodi yesekethe kulawulo olukude luye lwangcoliseka, olwenza ukuba ukonyuka koqhakamshelwano kunyuke okanye kungenakudityaniswa. Umqhaphu ofakwe kwisiselo esinxilisayo ungasetyenziselwa ukosula iifowuni zekhabhoni, kodwa hayi kunzima kakhulu ukuthintela ifilimu yekhabhoni ekubeni inxibe okanye iwe. Ukwaluphala okanye ukunxiba irabha eqhubayo kunokubangela ukuba iibhondi ezizodwa zingasebenzi. Ngeli xesha, okoko indawo yokudibanisa irabha eqhubayo incanyathiselwe kwibhokisi ye-cigarette tin (ngokukhethekileyo i-aluminium foil adhesive) zama. Ukuba ezi ndlela zingasentla azinakwenza isilawuli esikude sibuyele ekusebenzeni kwesiqhelo, jonga ukuba ngaba kukho ukuqhekeka okanye ukunxibelelana okungalunganga kwisekethe ukusuka kwigalelo lokufaka isitshixo kunye nokuphela kwesiphelo kwindawo yoqhakamshelwano kwibhloko edityanisiweyo, ngakumbi kunxibelelwano phakathi kwekhabhoni Ukuqhagamshelana nefilimu kunye nomgca wesekethe. Ukuba kukho imfuneko, buyisela ibhloko edityanisiweyo.
