Bangane, sekuyisikhathi sokufingqa imiphumela yephrojekthi yethu yokuncintisana "Iseva Emafu". Uma kukhona ongazi, siqale iphrojekthi ye-geek ejabulisayo: senze iseva encane ku-Raspberry Pi 3, sanamathisela i-GPS tracker nezinzwa kuyo, salayisha zonke lezi zinto ebhaluni lomoya oshisayo futhi sayiphathisa amandla emvelo. . Lapho ibhola lizofika khona laziwa kuphela onkulunkulu bemimoya kanye nabaxhasi bezindiza, ngakho-ke simeme wonke umuntu ukuthi abeke amaphuzu ebalazweni - amaphuzu abo aseduze nendawo okufikela kuyo azothola imiklomelo "emnandi".
Ngakho-ke, iseva yethu isivele yandizela emafini, futhi sekuyisikhathi sokufingqa imiphumela yomncintiswano wethu.
Izixhumanisi ekushicilelweni kwangaphambilini mayelana nomncintiswano
- (umklomelo wendawo yokuqala emqhudelwaneni wethu ukubamba iqhaza ku-regatta kaseyili, ezoba kusukela ngo-November 3 kuya ku-10 eSaronic Gulf (Greece) kanye neqembu le-RUVDS ne-Habr.
- Senze kanjani"Β»iphrojekthi - yabalandeli be-geek porn, enemininingwane nokuhlaziywa kwekhodi.
- ngencazelo egcwele.
- , lapho kwakungenzeka khona ukuqapha ukunyakaza kwebhola kanye ne-telemetry ngesikhathi sangempela.
- ukusuka endaweni lapho ibhola liqaliswe khona.
Futhi isipiliyoni, indodana yamaphutha anzima
Njengoba ukhumbula, sihlele ukusakaza idatha kusuka kuseva ngemodemu ye-GSM. Lesi bekuyisiteshi esikhulu sokudlulisa ulwazi. Kubonakala kithi ukuthi sinikeze noma yiziphi izimangaliso ngenethiwekhi yeselula ngokufaka amakhadi amabili e-SIM avela kuma-opharetha anekhava engcono kakhulu esifundeni sase-Dmitrov kumodemu. Ngaphezu kwalokho, imodemu yayine-antenna enhle ye-omnidirectional. Kodwa, njengoba besho, umuntu uthatha, futhi i-opsos ilahla. Lapho ibhola liphakama ngaphezu kwamamitha angu-500 (ubude bombhoshongo we-TV we-Ostankino), ukuxhumana kwamaselula kwanyamalala ngokuphelele.
Uma ubheka emuva, kubonakala kusobala, kodwa yilokho okushiwo ukubheka emuva. Kunjalo, izimpondo zamaselula zenzelwe ukumboza phansi, hhayi emoyeni. Amaphethini abo emisebe "ashaya" eceleni kwempumuzo futhi "angakhanyi" emafwini. Ngakho ukuxhumana kwamaselula endaweni ephakeme enguhhafu wekhilomitha nangaphezulu kuwukubonakaliswa okungahleliwe kwelobe yothingo oluthile. Ngakho engxenyeni yomzila kwakungekho ukuxhumana nebhaluni ngesiteshi samaselula. Futhi ngesikhathi sokwehla, lapho sihamba ngaphansi kwamamitha angu-500, ukuxhumana kwamaselula kwaqala ukusebenza futhi.
Siyithole kanjani i-telemetry evela kubhaluni? Sibonga isiteshi sokudluliswa kwedatha esingasanele salokhu. Sifake ikhithi ebholeni, isebenza ku-433 MHz.
Ukuphuma kwayo kuncane, kodwa ngokwezinjongo zethu bekwanele. Mayelana nokunquma indawo yebhola kusetshenziswa i-GPS, azikho izinkinga ngalokhu; i-tracker isebenze ngaphandle kokuhixa.
Futhi ngesikhathi sendiza, kwavela ukuthi ikhebula le-USB elixhuma imojula ye-telemetry ku-Raspberry Pi 3 ibonakale inephutha. Wasebenza emhlabathini, kodwa wenqaba ukuya ezulwini. Mhlawumbe wesaba ukuphakama. Sithole iphutha lekhebuli ngemuva kokuhlala. Ngenhlanhla, sikwazile ukusungula ukudluliswa kwedatha ngqo kusuka kumojula ye-telemetry nge-LoRa.
Futhi mayelana nokuhle
Inhlanhla yamamatheka kuma-habrayusers @ (indawo yokuqala), @ (indawo yesibili) futhi @ (indawo yesithathu)! Umuntu onenhlanhla uzoba nokuvela okuningi (ngethemba lokuthi kuzoba kuhle) okuvela kuyo, futhi maduze sizokwethula ama-smartphones amahle kubaphathi bendawo yesibili neyesithathu. Futhi kunjalo, sobathathu sizothola ukuqashwa kwamahhala kweseva ebonakalayo evela ku-RUVDS njengesipho.
