Ikhomputha encinci yee-30 zama-computer ichazwe
Uyibukele kwiindaba, umhlobo wakho unalo kwaye uqinisekile ukuba akusikho ukutya. Uxelelwe ukuba "Ikhompyutheni engama-30 engena ephaketheni lakho" kodwa awukulungele ukukholelwa oko.
Ngoko, yintoni i-Raspberry Pi?
Ewe, ufike kwindawo efanelekileyo. Masichaze ukuba yintoni le bhodi elincinane eluhlaza, kutheni unokufuna enye kunye nendlela ekutsalwe ngayo enkulu.
Isingeniso soBoniso
Masiqale ngomfanekiso wenguqulo yakutshanje, iRaspberry Pi 3.
Xa abantu bakutshela i-Raspberry Pi "i-computer ye-30" ikhuphela ukulibala ukuba uyifumana kuphela ibhodi yeendleko eziphambili. Akukho sikrini, akukho mqhubi, akukho miqobo kwaye akukho sikhokhelo. .
Ngoko Yintoni?
I-Raspberry Pi yinkqubo encinci eyenzelwe imfundo. Inayo yonke into oza kuyibona kwi-PC yentsapho yedeskithophu yenkqubo yedolophu - iprojector, i-RAM, i-HDMI port, i-output output kunye nee-port ze-USB zokongeza iiprayiphi njengebhodibhodi kunye ne mouse.
Ngaphandle kwezi zixhobo ezibonakalayo enye yezona zinto ziphambili zePi - i-GPIO (Injongo Yomxholo Wokufaka Injongo).
Le yibhloko yezikhonkwane ezikuvumela ukuba udibanise i-Raspberry Pi yakho kwilizwe lenene, ukudibanisa izinto ezifana nokutshintsha, ii-LED, kunye neentloko (kunye nokunye okuninzi) ongayilawula ngekhowudi elula.
Kwakhona isebenza inkqubo epheleleyo yokusebenza kwidesktop ngokusekelwe kwi-Linux Debian, ebizwa ngokuthi 'iRaspbian'. Ukuba oko akuthethi nto kuwe, cinga ukuba iWindows, i-Linux, kunye ne-Apple OS X zizo zonke iinkqubo zokusebenza.
I-PC yokuqhathaniswa iphelile apho
Ukuthelekisa kwi-PC eqhelekileyo yePacs desktop iphela iphela.
I-Raspberry Pi yindlela ephantsi (5V) encinci yekhompyutha. Inikwe amandla okunikezelwa kwamandla e-micro-USB afana nejaji yakho ye-smartphone kwaye unikezela amandla okusebenzisa iikhompyutha ngokufanayo kwisixhobo sakho sesefayili.
Ukusekwa kwamandla amancinci kukugqibeleleyo kwiprogram kunye neeprojekthi zekhompyutheni, nangona kunjalo, kuya kuziva uceceke ukuba uceba ukuyisebenzisa njengosuku lwakho lwePC.
I-Raspberry Pi 3 yakutshanje isinika ukusebenza okukhulu kunanini ngaphambili ngaphambili kwi-Raspberry Pi, kodwa i-desktop environment ayiyi kuva ngathi i-snappy njengekhompyutha yakho yasekhaya.
Yintoni na ngoko?
I-Pi ayilungiselelwe ukuba ibe yi-PC yakho elandelayo ye-PC, kwaye ngaphambi kokuba ubuze, akukho nto ayiyiyo iWindows! Ayifuni kwimeko kwaye mhlawumbi akayi kubona ithatha indawo ye-PC kwiofisi nanini na ngokukhawuleza.
I-Pi ijonge ngakumbi kwiiprogram kunye ne-electronics, ekuqaleni ekudalwe ukujongana nenani elinciphileyo labafundi abanezakhono kunye nomdla kwi-computer yesayensi.
Nangona okokuba ukutyekela nokubonakala kwayo kuye kwanda, abantu babo bonke ubudala kunye nemvelaphi baye badala uluntu olukhulu oluthandayo oluthandayo ukufunda.
Yintoni Engayenza Ngayo?
Ukuba ufuna ukusebenzisa iPi yakho ukuphucula izakhono zakho zokubhala, ungasebenzisa enye yeelwimi ezininzi ezixhaswayo (njengePython) ukudala zakho iinkqubo. Oku kungabikho kwinto yokushicilela nje "Hello world" kwesikrini, ukuya kwiiprojekthi ezinzima ezifana nokwenza imidlalo yakho.
Abo abanomdla kwi-hardware kunye ne-electronics bangakwazi ukuphucula le nkqubo ngokusebenzisa iGPIO ukuba bafake ukutshintsha, iinjenisi kunye neenjongo zangempela zomzimba 'zokufakelwa' ukuthetha nale khowudi.
Ungongeza kwakhona 'iziphumo' ezifana ne-LED, izithethi kunye neenjini ukuba zenze 'izinto' xa ikhowudi yakho ibatshela. Beka ezi zinto kunye kwaye unokwenza into enjengebhobhothi ngaphandle kwexesha.
Ukufuduka kwiprogram, kukho inani elikhulu labasebenzisi abathengayo iPi njengenye indlela kwezinye iifowuni. Ukusebenzisa iPi njengeziko le-media le-KODI yiprojekthi eyaziwayo kakhulu, umzekelo, ukuqhutyelwa kwexabiso elibi kakhulu 'ngaphandle kwesikhalazo'.
Kukho nezinye izinto ezininzi ezisetyenziswayo, amawaka ngokwenene. Siza kuhlanganisa ezinye zezi zinto kungekudala.
Akukho Mvelaphi efunekayo
Mhlawumbi ucinga ukuba ufuna iprogram yangaphambili okanye i-electronics experience ukuze uhambelane nale bhodi encinane eluhlaza. Lo mbono onobuhlungu ukuba ndicinga ukuba uchithe amawaka wabasebenzisi abasebenzisi.
Akunakudingi imbali enkulu kunye neekhompyutheni ukuqala ukusebenzisa i-Raspberry Pi. Ukuba sele usebenzisa i-PC okanye i-laptop, uya kulungeleka. Ewe, uya kuba nezinto ezinokuzifunda, kodwa yile ngongoma.
Andizange ndibe ngumprogram okanye umbane wecala xa ndiqala. Ndandinomdla kwiikhompyutheni kwaye ndandidla ngokukwakhiwa kwePC, kodwa ndandingenaso imvelaphi yolwazi nonke.
Nangona kunjalo, izihlwele zemithombo yoluntu kunye nenkxaso yoluntu ngokuqinisekileyo isiqinisekiso sokuba awuyi kubambelela. Ukuba ungasebenzisa iGoogle, ungasebenzisa i-Raspberry Pi!
Kutheni kuDume kakhulu?
Ukuthandwa kukaRaspberry Pi kunye nempumelelo eqhubekayo ngenxa yexabiso elifikelelekayo kunye noluntu oluhle.
Kwimali eyi-30 kuphela sele ithande uluhlu oluninzi lwabasebenzisi abavela kubantwana besikolo ukuya kubafundi bezakhono, kodwa ixabiso aliyena kuphela into apha.
Ezinye iimveliso ezifanayo eziye zazama ukuthenga imali kule mali zithenganga, kwaye kungenxa yokuba uluntu malunga nePaspberry Pi yinto eyenza lukhetheke kakhulu.
Ukuba uyanamathela, udinga iingcebiso okanye ufuna nje ukuphefumlelwa, intanethi igxininisa kunye nabasebenzisi abanikezela ngoncedo ngokusebenzisa iibhola, ii-blogs, amanethiwekhi omnxeba kunye nokunye.
Kukho namathuba okuhlangana nomntu kwi-'Raspberry Jams 'apho abantu abanomdla-nxaxheba beza kunye ukuze bahlanganyele iiprojekthi, bajongane neengxaki kunye noluntu.
Ndingafumanaphi enye?
Siza kushicilela i-Raspberry Pi yokuthenga isikhokelo ngokukhawuleza, njengoko kunokudideka okokuqala ngenxa yenani leemodeli ezahlukileyo ezithengiswayo. Ukuba awukwazi ukulinda kude kube yilapho, zilapha ezinye zeendawo zokugcina ezithengayo:
UK
Xa ibhodi izalwa e-UK, kukho ngokwemvelo izitolo ezininzi ze-Pi kwisiqithi sethu esiluhlaza. Iip Pi eziphambili njenge-Pi Hut, i-Pimoroni, i-ModMyPi, i-PiSupply ne-RS Electronics iya kubabeka kwisitokhwe kwaye zilungele ukuthumela.
i-USA
E-Amerika, izikhululo zamandla kagesi njengeSikhungo seMicrosoft ziza kuba ne-stock efanelekileyo yePi, njengoko iya kwenza iNewark Element14 kunye nabenzi bezitolo ezifana neAdafruit.
Ukuphumla kwehlabathi
Amanye amazwe anayo izitolo zePi apha naphandle, kodwa ukutyekwa akukomelelekanga njenge-UK ne-USA. Ukujonga ngokukhawuleza kwi-injini yosesho yelizwe kufuneka kuvelise iziphumo zendawo.
