Justine Haupt (Justine Haupt) ya ci gaba bude wayar hannu tare da dialer rotary. An yi mata wahayi ta hanyar ra'ayin 'yantar da bayanai daga ko'ina, wanda saboda haka mutumin zamani ya shiga cikin tarin bayanan da ba dole ba.
Sauƙin amfani da wayar ba tare da tabawa yana da mahimmanci ba, don haka ci gabanta na iya nuna ayyukan da ba a samu ba tukuna ga yawancin wayoyi na zamani:
- Kasancewar eriyar SMA mai cirewa, tare da ikon maye gurbinta da na'urar kwatance, don amfani da na'urar a wuraren da ke da wahalar karɓar hanyar sadarwar salula.
- Yin kira yana da sauƙi da sauri fiye da yin amfani da daidaitaccen ƙirar taɓawa - babu buƙatar shiga cikin menu.
- Akwai aikin “dial ɗin sauri” kamar yadda a cikin maɓallan turawa na yau da kullun - ana iya haɗa lambobi zuwa maɓallan jiki don kiran gaggawa.
- Ana nuna matakin sigina da cajin baturi akan alamar LED.
- An gina allon a ciki ta amfani da fasahar e-ink, wanda baya buƙatar ƙarin amfani da makamashi don nuna bayanai.
- Firmware kyauta da buɗewa - kowane mai amfani yana iya yin nasu canje-canje a cikin sauƙi da ta halitta, yana karɓar ƙarin ayyuka. Tare da ikon yin shiri, ba shakka.
- Maimakon riƙe maɓallin wuta, ana iya kunna na'urar ta amfani da maɓalli na jiki na yau da kullun.
Wasu halaye:
- Na'urar ta dogara ne akan microcontroller ATmega2560V.
- An rubuta firmware mai sarrafawa ta amfani da Arduino IDE.
- Don aiki tare da cibiyar sadarwar salula, ana amfani da tsarin rediyo na Adafruit FONA, tushen abin da akwai akan GitHub. Hakanan yana goyan bayan 3G.
- Don nuna mahimman bayanai, ana amfani da allo mai sassauƙa bisa tawada na lantarki.
- Alamar LED na matakin caji da siginar cibiyar sadarwar salula ya ƙunshi LEDs masu haske 10.
- Baturin yana ɗaukar caji na kimanin awa 24.
Akwai don saukewa:
- Tsarin na'ura da shimfidar PCB a cikin tsarin KiCAD.
- Samfura don buga akwati akan firinta na 3D a tsarin STL.
- Ƙayyadaddun abubuwan da aka yi amfani da su.
- Lambobin tushen firmware.
Ga waɗanda ba za su iya buga harka ba kuma su haɗa allon da'irar da aka buga da kansu, an shirya shirye-shiryen abubuwan da suka dace, waɗanda za a iya ba da oda daga marubucin. Farashin farashin $170. Ana iya yin odar hukumar daban akan $90. Abin takaici, kit ɗin bai haɗa da dialer ba, FONA 3G GSM module, e-ink screen control, GDEW0213I5F 2.13" allon, baturi (1.2Ah LiPo), eriya, masu haɗawa da maɓalli.
