Taleefanka gacanta oo furan oo wareeg ah ayaa diyaar ah

Justine Haupt diyaarisay teleefan gacanta oo furan oo ay ku rakiban tahay dialer rotary ah. Wixii rarista la heli karo Jaantusyada PCB ee KiCad CAD, moodooyinka STL ee daabacaadda 3D ee kiiska, qeexida qaybaha la isticmaalay iyo koodka firmware-ka, taasoo fursad siinaya qof kasta oo xiiseeya si loo ururiyo qalab naftaada.

Si loo xakameeyo aaladda, ATmega2560V microcontroller oo leh firmware lagu diyaariyay Arduino IDE ayaa la isticmaalaa. Module GSM waxa loo isticmaalaa in lagula falgalo shabakadaha gacanta Adafruit FONA oo leh taageerada 3G. Si loo muujiyo macluumaadka, shaashad dabacsan oo ku salaysan warqad elektaroonig ah ayaa la isticmaalaa (ePift). Kharashka batarigu wuxuu socdaa qiyaastii 24 saacadood.
Tilmaame dhinaca 10 LEDs ayaa loo isticmaalaa si firfircooni leh loogu muujiyo heerka signalka.

Kuwa doonaya inay dadka kale kaga yabaan taleefanka gacanta ee wareega ah, laakiin aan fursad u helin inay daabacaan kiiska oo ay ku dhejiyaan guddiga wareegga daabacan, soo jeediyay qaybo ka mid ah isu imaatinka: case + board $170 iyo sabuur kaliya $90. Qalabka kuma jiraan dialer, FONA 3G GSM module, eInk screen controller, GDEW0213I5F 2.13″ shaashad, baytari (1.2Ah LiPo), anteeno, xirayaasha iyo badhamada.

Abuuritaanka mashruuca ayaa lagu macneeyay rabitaanka helitaanka talefan casri ah oo aan caadi ahayn kaas oo bixin doona dareenka la taaban karo inta lagu jiro hawlgalka aan la heli karin badhanka iyo taabashooyinka telefoonada, iyo sidoo kale u oggolaanaya mid ka mid ah inuu caddeeyo diidmada qofka inuu la xiriiro isagoo isticmaalaya fariimaha qoraalka ah. Waxaa la xusay in casriga casriga ah ee casriga ah, dadku ay si xad dhaaf ah ugu raran yihiin aaladaha isgaarsiineed oo ay joojiyaan xakameynta qalabkooda.

Markaad ku shaqeyneyso qalabka, ujeedadu waxay ahayd in la abuuro telefoon ku habboon, isdhexgalka kaas oo ka duwanaan doona inta suurtogalka ah ee ku salaysan muraayadaha taabashada. Isla mar ahaantaana, meelaha qaar talefanka ka dhashay ayaa ka horreeya talefannada casriga ah ee caadiga ah ee shaqaynta, tusaale ahaan:

• Anteeno la saari karo oo leh isku xirka SMA, kaas oo lagu bedeli karo anteenada jihada ee ka shaqeynta meelaha caymisku liito ee hawlwadeenada gacanta;
• Si aad u wacdo, looma baahna in lagu dhex maro liiska oo lagu sameeyo ficillada codsiga;
• Tirooyinka dadka inta badan la waco waxaa lagu meelayn karaa inay kala soocaan badhamada jirka. Nambarada la garaaco waxay ku kaydsan yihiin xusuusta oo uma baahnid inaad isticmaasho garaaca si aad dib ugu garaacdo;
• Tilmaamaha LED-ka ee madax-bannaan ee kharashka batteriga iyo heerka signalka, ku dhawaad ​​isla markiiba ka jawaabaya isbeddelada xuduudaha;
• Shaashada elektaroonigga ah uma baahna awood ay ku soo bandhigto macluumaadka;
• Awood u lahaanshaha in aad u bedesho hab-dhaqanka taleefanka dhadhankaaga adiga oo tafatira firmware-ka;
• Isticmaalka furaha halkii aad badhan ku hayn lahayd si aad u damiso oo aad u damiso aaladda.
