Justine Haupt (Justine Haupt) ithuthukile vula umakhalekhukhwini nge-rotary dialer. Waphefumulelwa umqondo wokukhululwa ekugelezeni okukhona yonke indawo kolwazi, ngenxa yokuthi umuntu wanamuhla ugcwele amathani olwazi olungadingekile.
Ukusebenziseka kalula kwefoni ngaphandle kwesikrini sokuthinta kwakubaluleke kakhulu, ngakho-ke ukuthuthukiswa kwayo kungabonisa imisebenzi engakatholakali kuma-smartphones amaningi anamuhla:
- Ukuba khona kwe-antenna ye-SMA ekhishwayo, enekhono lokuyishintsha ifakwe eqondisayo, ngokusebenzisa idivayisi ezindaweni ezinokwamukela okunzima kwenethiwekhi yeselula.
- Ukushaya ucingo kulula kakhulu futhi kuyashesha kunokusebenzisa isixhumi esibonakalayo sokuthinta - asikho isidingo sokudlula kumenyu.
- Kunomsebenzi "wokudayela ngokushesha" njengasezidayelini ezivamile zenkinobho yokusunduza - izinombolo zingaxhunyaniswa nezinkinobho ezibonakalayo ukuze uthole izingcingo ezisheshayo.
- Izinga lesiginali kanye nokushajwa kwebhethri kuboniswa kusibonisi se-LED.
- Isikrini esakhelwe ngaphakathi senziwa kusetshenziswa ubuchwepheshe be-e-ink, obungadingi ukusetshenziswa kwamandla okwengeziwe ukuze kuboniswe ulwazi.
- I-firmware yamahhala nevulekile - umsebenzisi ngamunye angenza kalula futhi ngokwemvelo izinguquko zakhe kuyo, ethola imisebenzi eyengeziwe. Ngekhono lokuhlela, kunjalo.
- Esikhundleni sokubamba inkinobho yamandla, idivayisi ingavulwa kusetshenziswa ukushintshwa okujwayelekile komzimba.
Ezinye izici:
- Idivayisi isuselwe kusilawuli esincane se-ATmega2560V.
- I-firmware yesilawuli ibhalwe kusetshenziswa i-Arduino IDE.
- Ukuze usebenze nenethiwekhi yamaselula, kusetshenziswa imojula yomsakazo ye-Adafruit FONA, imithombo yayo iyatholakala ku-GitHub. Iphinde isekele i-3G.
- Ukuze ubonise ulwazi oludingekayo, isikrini esivumelana nezimo esisekelwe kuyinki ye-elekthronikhi sisetshenziswa.
- Inkomba ye-LED yeleveli yokushaja nesignali yenethiwekhi yeselula iqukethe ama-LED akhanyayo ayi-10.
- Ibhethri libamba ukushaja cishe amahora angama-24.
Iyatholakala ukuze ilandwe:
- Umdwebo wedivayisi nesakhiwo se-PCB ngefomethi ye-KiCAD.
- Amamodeli wokuphrinta ikesi kuphrinta ye-3D ngefomethi ye-STL.
- Imininingwane yezingxenye ezisetshenzisiwe.
- Amakhodi omthombo we-Firmware.
Kulabo abangakwazi ukuphrinta icala futhi bahlanganise ibhodi lesifunda eliphrintiwe ngokwabo, isethi esenziwe ngomumo yezingxenye ezidingekayo isilungisiwe, esingayalelwa kumlobi. Intengo yokukhishwa ngu-$170. Ibhodi linga-odwa ngokwehlukana ngo-$90. Ngeshwa, ikhithi ayifaki okokudayela, imojuli ye-FONA 3G GSM, isilawuli sesikrini se-e-ink, isikrini se-GDEW0213I5F 2.13", ibhethri (1.2Ah LiPo), uthi, izixhumi nezinkinobho.
>>> Landa imithombo kanye nokucaciswa
>>> Oda izingxenye
Isithombe sedivayisi, amasekhethi kanye nebhodi: 1, 2, 3, 4, 5, 6, 7.
Isithombe sombhali ngedivayisi
