Ingcamango yokubhala ikhowudi ngaphandle kwekhowudi yokubhala (ewe, ukubhala yinxalenye yangoku yesenzi sokubhala, ukuhlala nayo ngoku) ifikile kwiingqondo zabantu abahlakaniphile kunye namavila ngaphezu kweyodwa. Iphupha lojongano lomzobo apho unokuphosa idayisi kwabanye, uzobe uqhagamshelo olulinganayo kwaye ukhethe iipropathi zezinto kuluhlu oluhle lokuhla, emva koko, ngokucinezela iqhosha lomlingo elithi "Qokelela", fumana ikhowudi yokusebenza elingana nekhowudi. yenye (engekho krelekrele kangako, kunjalo) umdwelisi wenkqubo osebenzisa indlela yakudala yokuchwetheza ngesandla ebesoloko eqhuma ezingqondweni zabo bobabini abaphathi bequmrhu abaphuphayo ukwazisa umfundi ngamnye wayizolo kwiprogram, ingqondo yakhe yamvumela ukuba angaphoswa yindlu yangasese, kwaye abaqalisi abafuna ukwenza umhlaba wonke wonwabe ngexabiso elaneleyo. Namhlanje sikuzisa:
Iprojekthi yeCrowdfunding: Ezblock Pi.
Undoqo weprojekthi: Ubume benkqubo yomzobo yeRaspberry Pi ngokuhambelana nebhodi yokwandisa.
Platform: Umqalisi.
Idilesi yeprojekthi: .
AuthorsIinkwenkwezi: uGeorgne Chang, uReggie Lau.
Indawo: USA, Delaware, Wilmington.
Iinzame zokuphuhlisa imeko yenkqubo yemizobo ziye zaphela ngokuthe ngcembe; nabaphathi abaphezulu baqonda ukuba inkqubo yokucwangcisa yayinzima kakhulu ukuba ingene kwibhedi yeProcrustean yeetyhubhu ezinemibala emininzi. Ngethamsanqa, kusekho abadwelisi benkqubo abasele besafunda, kwimeko yeprojekthi yokuxhasa ngemali ekuthethwa ngayo - abathandi beRaspberry Pi. Ukuze bangakhuthazi isoftware engenanto, ababhali bongezelela indawo yophuhliso lomzobo kunye nebhodi yokwandisa, eyenzelwe ukuququzelela inkqubo yokudibanisa nezixhobo zangaphandle.
Kwiphepha leprojekthi, kwividiyo yesihloko, saziswa kwiinkqubo ezimbini zerobhothi, uRobert noEmily. URobert, njengawo wonke umntu ozihloniphayo kunye neeglasi ezinxibayo, iikhowudi kwiPython ngendlela yakudala, usebenzisa imonitha kunye nekhibhodi. Kwimeko ka-Amy, izandla ezikhathalayo zomntu, zibhabha ukusuka kumda wesakhelo, zisuse ikhibhodi, ukubeka iliso kunye nemouse, ukuyibuyisela yonke ngethebhulethi emhlophe. Ithebhulethi, yona, iqhuba inkqubo ebizwa ngokuba yi-Ezblock Studio, ekuvumela ukuba ubhalele i-IoT esefashonini ngoku kwi-Drag-n-Drop-n-be-happy style.
Ngokwemvelo, ngelixa uRobert ehluleka umzamo emva kokuzama (mhlawumbi ngenxa yokusetyenziswa kwekhibhodi yokudlala), irobhothi uEmily unkcenkceshela ngempumelelo isityalo ngamanzi avela kwiglasi, intombazana ngokwayo ifumana izaziso ezivela kwirobhothi ngqo kwifowuni yakhe kwaye ide ikhuphe imiyalelo yokuphendula. usebenzisa ulawulo lwelizwi.
Kuba izikwere zisafuna ukuncamatheliswa kunye nolunye uhlobo lwengqiqo, ukuya esiphelweni sevidiyo, ekugqibeleni kwabhengezwa inkxaso yolwimi lwenkqubo, ezi ziPython kunye neSwift (umlinganiswa ophambili wevidiyo, ithebhulethi, une apple logo). Kuphela ngoku uAmy kufuneka acofe kwikhibhodi ekwiscreen, kuba akukho mntu ubuyisele eyesiqhelo kuye. I-Ezblock Studio ithi ixhasa i-iOS, i-Android, i-Linux, iWindows kunye ne-macOS. Wonke umntu wonwabile. Ewe, mhlawumbi ngaphandle kukaRobert, owanyamalala phakathi kwevidiyo; Mhlawumbi wazintyintya ngotywala okanye wayeka.
Kulungile, ndicinga ukuba zizinto zoncwadi ezaneleyo. Ngaphandle kwesiphithiphithi, makhe sibone ukuba abaphuhlisi basinika ntoni nge35 yeedola.
Iprojekthi ye-Ezblock Pi kuqwalaselo lwayo oluncinci lubandakanya iinxalenye ezintathu:
- ibhodi ye-Ezblock Pi ngokwayo, esetyenziswa njengebhodi yokwandisa iRaspberry Pi;
- isethi eyisiseko yeemodyuli ze-15 (kukho kwakhona isethi yeemodyuli ze-IoT, ezithengiswa kwisethi ebiza kakhulu kwi-$ 74, ngaphezulu kwezantsi);
- ukufikelela kwi-Ezblock Studio, ekuvumela ukuba ubhale isoftware yeRaspberry Pi usebenzisa i-Drag-n-Drop manipulations;
- iplastiki yeplastiki yokuhlanganisa iRaspberry Pi + Ezblock Pi;
- Umyalelo.
Ngemeko kunye nemiyalelo, ndicinga ukuba yonke into icacile, makhe sihlolisise amanqaku amathathu okuqala.
I-hardware yebhodi ye-Ezblock Pi inokugwetywa kuphela ngokukhankanywa "kwenkxaso yesilawuli se-STM32" kunye nefoto efizileyo yeprototype yokuqala. Kubonakala ukuba, ibhodi iqulethe i-STM32 microcontroller kwiphakheji ye-TQFP32. I-microcontroller engabizi kakhulu kule phakheji, i-STM32L010K4T6 (i-ARM Cortex-M0 +), ixabisa i-0,737 ye-β¬ 100 ngobuninzi beeqhekeza ezili-32; eyona ibiza kakhulu, STM334F8K6T4 (ARM Cortex-M2.79) - β¬3.3 (amaxabiso eMouser). Amandla anikezelwa yi-223 V ye-stabilizer ye-linear kwi-SOT-12 iphakheji, kwaye i-Bluetooth inikezelwa yimodyuli esele ilungile, ngokujonga ukubonakala kwayo, into efana ne-ESP20E. Izixhumi ezimbini ze-XNUMX-pin kunye nebala le-breadboard phakathi kwebhodi linoxanduva lokuqhagamshelana nehlabathi langaphandle.
Ukuqulunqwa kwesiseko esisisiseko seemodyuli ze-15, ukunyaniseka, kwahlala kuyimfihlakalo kum, nasemva kokuphonononga ngokusondeleyo imifanekiso yeprojekthi. Ukuba iiseti ezipheleleyo zeemodyuli ze-IoT zifotwe ngokunyanisekileyo kwaye zithiywe igama, ke iseti esisiseko ebandakanyiweyo kwiphakheji yokuqala ifihlakele ngakumbi kunoyilo lwemoto entsha phambi komboniso omkhulu wemoto. Isethi esisiseko ikuvumela ukuba "udale iiprojekthi ezili-15 ezahlukeneyo," kodwa kwimizekeliso kukho iibhokisi zekhadibhodi ezili-10 ezibonakala ziqulethe uhlobo oluthile lwamacandelo e-elektroniki ngaphakathi, kodwa ukubunjwa okupheleleyo kwesethi esisiseko akukaze kuchazwe.
Ngokuphathelele i-Ezblock Studio, bendisele ndabelana ngokuthandabuza kwam ekuqaleni kweendaba. Ngokombono wam, inkqubo eya kuthi ikwazi kakuhle zonke iinketho ezikhankanyiweyo (makhe ndikukhumbuze: (ibhloko inkqubo + Python + Swift) * (iOS + macOS + Android + Linux + Windows) inokuphuhliswa kakuhle, kodwa ndingabhajetha. kuphuhliso lwesoftwe enjalo malunga nento efana neminyaka emi-5 okanye unyaka omnye womsebenzi kwiqela labantu abahlanu (ungayinika malini?), Naxa usebenzisa uhlobo oluthile lwe-multitool, njenge-Electron. Ukuqwalasela ukuba abaphuhlisi babanga i-$ 10000 kuphela (iprojekthi ibonakala ivuya kakhulu, ngoko ngoku i-400% yale mali sele iqokelelwe), akucaci ngokupheleleyo ukuba eli qela liya kudla ntoni ngexesha lonke lophuhliso. Ngetyala lababhali, kufuneka songeze ukuba inguqulelo yokuqala ye-Ezblock Studio sele ikhona kuDlalo lukaGoogle.
Umbhalo wenkcazo-ntetho uqulethe iindlela zokuchwetheza eziqhelekileyo kubenzi baseTshayina; kule meko, imotor yokungcangcazela ebandakanyiweyo kwiseti yeemodyuli ze-IoT ibizwa ngokuba yi "Vabration Module" endaweni ye "Vibration Module". Nangona kunjalo, ngeli xesha abaphuhlisi bokwenyani abacingi nokucinga ngokufihla; Nceda, nantsi ifoto yeqela labahlali bedolophu yaseWilmington, eDelaware:
Ungandivi kakubi, andixolanga kwaphela ngenxa yesimo sengqondo esibi malunga nabaphuhlisi abavela kwi-PRC. Oku, ngokubanzi, i-fait accompli - okokuqala, abaprogram baseTshayina bathatha i-chunk ebalulekileyo ye-Google Play kunye ne-Apple App Store ye-app Store, kwaye ngoku baphumelele indawo yabo elangeni ngoncedo lwamaqonga e-crowdfunding. I-Crowdfunding ilungile kuba ivumela phantse nawuphi na umhlaba one-Intanethi kunye nekhadi lebhanki ukuxelela umhlaba wonke malunga nophuhliso lwakhe kwaye ngamanye amaxesha wenze imali entle kuyo. Ukungakhathali kunokubangelwa kuphela lutshintsho olumandla ngokugqithisileyo kugxininiso olusuka kwicandelo lobugcisa leprojekthi ukuya ekuthengisweni komnyama, xa iziphene [ezinokwenzeka] zoyilo zithulisiwe, kwaye icala leemvakalelo kunye nolonwabo libaxwa kakhulu. Nanku omnye umzekeliso ovela kumboniso we-Ezblock Pi:
Njengoko i-blogger yevidiyo u-Evgeniy Bazhenov aka BadComedian uthi, "ukuhlelwa kombhali" kugcinwe. Ngaba unazo naziphi na iingcinga malunga nokuba, ukwingqondo ephilileyo kunye nememori ephilileyo, usebenzisa iRaspberry Pi kunye ne "Vibration Module" ukwakha LENTO? Okanye ngaba oku kusengumnxeba wokungazi kakuhle kwethu: "Jonga indlela epholile ngayo, yithenge ngokukhawuleza!"?
Ukuthatha okanye ukungathathi? Okokuqala, makhe ndikukhumbuze ukuba abantu abangama-509 sele benikele ngeedola ezingama-41000 (kunye ne-10000 eceliwe), kwaye kusekho phantse iiveki ezi-3 eziseleyo kude kube sekupheleni kwephulo. Abantu bayayithanda. Mhlawumbi, ukuba ungumlandeli weRaspberry Pi, uya kubona kwakhona imiba elungileyo kuyilo olucetywayo, ukodlula ukungafuni ukwahlukana nesixa esisuka kwi-35 yeedola ukuya kwi-179 yeedola. Mhlawumbi nawe, njengoRobert ovela kwividiyo yentengiso, udiniwe βkukubhala iikhowudi eziphindaphindayo.β Okanye mhlawumbi ucinga ukuba abafana bahamba kwicala elifanelekileyo kwaye ufuna ukubaxhasa ngenaliti yakho yezemali. Khumbula nje ukuba iRaspberry Pi ngokwayo ithengiswa ngexabiso elilinganayo le-35 yeedola (andizukulikhankanya ngokucokisekileyo ixabiso leRaspberry Pi Zero kunye neRaspberry Pi Zero W apha), apho iqela leenjineli kwafuneka lisebenze nzima ukuyila, kwaye. exhaswa yi-ARM Cortex-A53 enesantya sewotshi ye-1,4 GHz, 1000 Mbit Ethernet, Wi-Fi 802.11n kunye neBluetooth 4.2.
Ndiqhuba encinci , endilithathe kulo eli nqaku. Ukuba uneprojekthi ye-crowdfunding enomdla engqondweni kwintsimi ye-DIY okanye i-Open source hardware, yabelana ngekhonkco kwaye siza kuxoxa ngayo. Amaphulo eCrowdfunding ayadlula kwaye abotshelelwe kakhulu kwinkxaso yoluntu, kwaye mhlawumbi komnye umntu onomdla, nokuba inani elincinci lemiyalelo evela kuHabr liya kunceda ukuzisa eli phulo kwisiphelo esoyisayo.
