Ngingavula kanjani ifoni ngaphandle kwebhethri ngamathuluzi atholakalayo?

Ekuphileni kunezimo lapho ulinde ucingo olubalulekile futhi kuyamangala ukuqonda ukuthi ibhethri ye-smartphone ikhishwa ngokuphelele. Ngemva kokufunda isihloko sanamuhla, uzofunda ukuthi ungavula kanjani ifoni ngaphandle kwebhethri.

Lesi sidingo sivela nini?

Ekuboneni kokuqala, lokhu kungolwazi olungenalutho, okungeke kube usizo kunoma ubani olandela isimo sebhethri yedivayisi yakhe. Kodwa-ke, ulwazi mayelana nokufaka ifoni ngaphandle kwebhethri lungaba usizo ezimweni lapho igajethi isetshenziswa njengesinye sezici zesistimu yokuphepha.

Futhi, lolu lwazi luzoba usizo uma kunesidingo sokwenza ucingo oluphuthumayo, uma ibhethri yefektri iyalwe ukuba iphile isikhathi eside. Ake sithi uthenge i-smartphone entsha, futhi omdala wayebuthele uthuli isikhathi eside etafuleni. Ngenxa yalokho, ibhethri yayo ikhululiwe ngokuphelele, futhi amafayela oyidingayo agcinwa kwimemori yedivayisi. Ukuze ufike kubo, ungathengi ibhethri entsha. Kungenxa yezimo ezinjalo abantu abavame ukuba nombuzo mayelana nokuvula ifoni ephathekayo ngaphandle kwebhethri.

Uma kwenzeka ukuphuthumayo, ungazama ukuvuselela "idivayisi" ngokushesha. Ungakwenza lokhu ngezindlela eziningana ezahlukene.

Kuyothatha ukuthini ukufeza umphumela oyifunayo?

Ukuze uvule i-smartphone ngokugcwele, udinga ukubeka isitoreji se-stabilization power unit, i-voltmeter, i-flux, i-rosin, i-solder, i-soldering iron, i-USB-cord kanye nokunikezwa amandla okungaxhunyiwe. Ngephakheji elilula ungakwazi ukubuyisela kabusha ngokuzenzakalelayo idivayisi yeselula.

I-algorithm yezenzo

Labo abangakwazi ukuvula ibhethri ngaphandle kwebhethri, kufanele bakhumbule ukuthi ishaja ejwayelekile iklanyelwe ukusebenza kanye nebhethri eyisisekelo ekwazi ukukhipha isikhathi esifushane samanje okwamanje. Uma uxhuma ngqo i-smartphone kuyo, okokuqala uvula umthumeli, i-voltage izokwehla cishe ku-zero.

Ngaphambi kokuba uvule ibhethri ngaphandle kwebhethri, udinga ukuthola ukunikezwa kwamandla okuzinza ngokuvikelwa okuzakhelwe ngokumelene ne-short-circuit. Idivayisi enjalo ingathengwa esitolo esikhethekile noma eyenziwe ngokuzimela. I-voltage eyenza yona kufanele ibe ngu-3.7 V.

Vala ifoni ephathekayo bese uyiqhaqa ishaja ejwayelekile futhi ususe ibhethri. Okulandelayo, udinga ukuthola ibhethri oxhumana nabo ababili, i-voltage ehlukahluka kusuka ku-3.2 kuya ku-3.7 V. Ungakwenza lokhu nge-voltmeter.

Ungakhohlwa mayelana nokugcinwa kwe-polarity, kufanele usebenzise i-voltage kubathintana abathintekayo ekamelweni lebhethri yeselula. Labo abakhetha ukusebenzisa le divayisi esikhathini esizayo kuphela njengesici se-system yokuphepha, ungakwazi ukuncoma ukuthi uvuse amandla okunikezwa amandla. Kungenzeka futhi ukuba izingxenyana zokuxhumeka kwe-solder.

Khona-ke udinga ukuvula ukunikezwa kwamandla bese uzama ukucupha idivayisi yeselula. Uma uphumelela, igajethi ayihlomele imoduli yokushintshanisa ulwazi kusuka ku-chip ekhonjiwe ebhetri. Lokhu kubonisa ukuthi kufanelekile ukusetshenziswa kwezinhlelo zokuphepha. Kulokhu, ifoni iyakwazi ukusebenza ngaphandle kwebhethri, kodwa kuphela ugesi.

Ukuze uqinisekise ukuphepha kwabo, kubalulekile ukugwema ukuhlola okufanayo futhi ukusebenzisa le ndlela kuphela ezimweni ezihlukile. Akudingekile ukusho ukuthi uma kwenzeka ukushisa okunamandla ibhetri yocingo ingaqhuma.

Ngingavula kanjani ifoni ngaphandle kwebhethri ngokusebenzisa isikhombimsebenzisi se-USB?

Ekuboneni kokuqala, lokhu kuyindlela elula futhi ecacile kakhulu. Kodwa empeleni konke kunzima kakhulu. Amadivayisi weselula ku-interface esibonakalayo se-USB angamukela amanje ngokulinganiselwa. Inkokhelo yesisekelo idlulisela okwamanje umshini we-smartphone. Uma uxhumeke kukhompyutha noma laptop ngekhebula le-USB, umkhawulo ungama-500 mA.

Labo abafuna ukuthola indlela yokuvula ibhethri ngaphandle kwebhethri, kuzodingeka bathole ithuba lokuxhuma ishaja ngaphandle kokusebenzisa ibhethri.
