Bangani, sesiqhamuke nomnyakazo omusha. Abaningi benu bayakhumbula iphrojekthi yethu ye-fan geek yonyaka odlule "": senze iseva encane esekelwe ku-Raspberry Pi futhi siyethula ngebhaluni lomoya oshisayo.
Manje sesinqume ukuqhubekela phambili, okungukuthi, phezulu - i-stratosphere isilindele!
Ake sikhumbule kafushane ukuthi yayiyini ingqikithi yephrojekthi yokuqala ethi "Iseva Emafu". Iseva ayizange ivele indize ibhaluni, ubuqili bekungukuthi idivayisi ibisebenza futhi isakaza i-telemetry yayo phansi.
Okusho ukuthi, wonke umuntu angalandelela umzila ngesikhathi sangempela. Ngaphambi kokwethulwa, abantu abangu-480 bamake kumephu lapho ibhaluni lingase lihlale khona.
Yiqiniso, ngokuhambisana ngokugcwele nomthetho ka-Edward Murphy, isiteshi esikhulu sokuxhumana ngemodemu ye-GSM "sawa" kakade sendiza. Ngakho-ke, abasebenzi bekufanele bashintshe ngokoqobo impukane baye ekusekeleni ukuxhumana okusekelwe . Amabhaluni nawo kwadingeka axazulule inkinga ngekhebula le-USB elixhuma imojula ye-telemetry kanye ne-Raspberry 3 - kubonakala sengathi yesaba ukuphakama futhi yenqaba ukusebenza. Kuhle ukuthi izinkinga ziphelele lapho futhi ibhola lahlala ngokuphepha. Laba abathathu abanenhlanhla omaka babo ababeseduze nendawo okufikela kuyo bathole imiklomelo emnandi. Kodwa-ke, okokuqala sikunikeze ukubamba iqhaza ku-regatta kaseyili ye-AFR 2018 (Vitalik, sawubona!).
Le phrojekthi ifakazele ukuthi umbono "wezinsiza ezihamba emoyeni" awuhlanyi njengoba ungase ubonakale. Futhi sifuna ukuthatha isinyathelo esilandelayo endleleni eya "esikhungweni sedatha endizayo": hlola ukusebenza kweseva ezokhuphuka ibhaluni ye-stratospheric ifike endaweni ephakeme engaba ngu-30 km - ku-stratosphere. Ukwethulwa kuzoqondana noSuku Lwe-Cosmonautics, okusho ukuthi, sekusele isikhathi esincane, ngaphansi kwenyanga.
Igama elithi "Server in the Clouds 2.0" alilungile ngokuphelele, ngoba ekuphakameni okunjalo ngeke ubone ifu. Ngakho singabiza iphrojekthi ngokuthi “Ngaphezu Kweseva Yefu” (iphrojekthi elandelayo kuzodingeka ibizwe ngokuthi “Baby, uyisikhala!”).
Njengakuphrojekthi yokuqala, iseva izoba bukhoma. Kodwa okugqamile kuhlukile: sifuna ukuhlola umqondo wephrojekthi edumile ye-Google Loon futhi sihlole ukuthi kungenzeka yini ukusabalalisa i-inthanethi kusuka ku-stratosphere.
Uhlelo lokusebenza lweseva luzobukeka kanje: ekhasini lokufika uzokwazi ukuthumela imiyalezo kuseva ngokusebenzisa ifomu. Zizodluliselwa ngephrothokholi ye-HTTP ngezinhlelo zokuxhumana zesathelayithi ezizimele ezi-2 kukhompyutha emiswe ngaphansi kwebhaluni le-stratospheric, futhi izodlulisela le datha eMhlabeni, kodwa hhayi ngendlela efanayo ngesathelayithi, kodwa ngesiteshi somsakazo. Ngale ndlela sizokwazi ukuthi iseva ithola idatha nhlobo, nokuthi ingasabalalisa i-inthanethi kusuka ku-stratosphere. Sizokwazi futhi ukubala amaphesenti olwazi olulahlekile “emgwaqeni onguthelawayeka”. Ekhasini lokubikezela elifanayo, ishejuli yendiza yebhaluni ye-stratospheric izoboniswa, futhi amaphuzu okwamukela umyalezo wakho ngamunye azomakwa kuyo. Okusho ukuthi, uzokwazi ukulandelela umzila nokuphakama kwe-"sky-high server" ngesikhathi sangempela.
Futhi kulabo abangakholwa ngokuphelele, abazothi lokhu konke ukusetha, sizofaka isikrini esincane ebhodini, lapho yonke imilayezo etholwe kuwe izoboniswa ekhasini le-HTML. Isikrini sizorekhodwa ikhamera, emkhakheni wokubuka lapho kuzoba khona ingxenye yomkhathizwe. Sifuna ukusakaza isignali yevidiyo esiteshini somsakazo, kodwa kukhona okungafani lapha: uma isimo sezulu sisihle, ividiyo kufanele ifinyelele phansi phakathi nesikhathi esiningi sokundiza kwebhaluni ye-stratospheric, ku-70-100 km. Uma liguqubele, ibanga lokudlulisela lingase lehlele kumakhilomitha angu-20. Kodwa kunoma yikuphi, ividiyo izorekhodwa futhi sizoyishicilela ngemva kokuthola ibhaluni ye-stratospheric ewile. Kodwa-ke, sizoyibheka sisebenzisa isignali evela kubhakhoni ye-GPS egibele. Ngokwezibalo, iseva izofika endaweni eyi-150 km ukusuka endaweni yokwethulwa.
Ngokushesha sizokutshela ngokuningiliziwe ukuthi imishini yokukhokha ibhaluni ye-stratospheric izoklanywa kanjani, nokuthi konke lokhu kuzodingeka kusebenze kanjani nomunye nomunye. Futhi ngesikhathi esifanayo, sizodalula eminye imininingwane ezithakazelisayo yephrojekthi ehlobene nesikhala.
Ukwenza kube mnandi kuwe ukulandela iphrojekthi, njengangonyaka odlule, siqhamuke nomncintiswano lapho udinga ukucacisa indawo yokuhlala kweseva. Owinile oqagele indawo yokufikela ngokunembe kakhulu uzokwazi ukuya e-Baikonur, lapho kwethulwa umkhumbi-mkhathi ophethwe umuntu we-Soyuz MS-13 ngoJulayi 6, umklomelo wendawo yesibili yisitifiketi sokuvakasha esivela kubangani bethu base-Tutu.ru. Abangu-XNUMX abasele abahlanganyeli bazokwazi ukuya ohambweni lweqembu oluya e-Star City ngoMeyi. Imininingwane ku .
Landela ibhulogi ukuze uthole izindaba :)
