Izindlela ezingu-10 ezahlukene zokwenza amaphrojekthi akho aseRaspberry Pi
Njalo imodeli ye-Raspberry Pi ihlale ifuna inani elincane elincane lamandla uma kuqhathaniswa nama-PC asebenza ngokugcwele.
Naphezu kokuthuthukiswa okunye kwezinto ze-hardware, ngisho ne-Raspberry Pi 3 yakamuva yanda lokhu kancane, okusho ukuthi amaphrojekthi aphathekayo ayeselula kunangaphambili.
I-Pi 3 ine-power supply enikezwa amandla ka-5.1V ku-2.5A, okuzokusibekela ezinkingeni eziningi lapho usebenzisa ibhodi ukuze ukwazi ukugcwele. Amamodeli ngaphambi kokuba afune i-5V ephansi kancane ku-1A, noma kunjalo, kusetshenziselwa ukuthi kusetshenziswe impi enkulu.
Emaphrojekthi amandla aphansi, unganciphisa indlela yokusebenza ngendlela ethile ngaphambi kokuthi uthinte ukusebenza noma ukuzinza, ngokuhlolwa okuncane kwesilingo nokuhlolwa kwephrojekthi ngayinye.
Ingxenye engcono kunazo zonke lokhu ukuthi awugcini nje kuphela egazini elilula le-adapter yedonga le-USB. Funda ukuze uthole izindlela ezingu-10 ezahlukene ongazisebenzisa amandla akho okusajingijolo Pi.
01 kwezingu-10
I-Supplied Power Supply
Yize kungenjalo okukhethwa kukho okuthakazelisayo kunazo zonke noma okunezintandokazi kulolu hlu, awukwazi ukushaya i-unit esemthethweni ye-Raspberry Pi unit unit (PSU) yokusebenza nokuzinza.
Inguqulo yakamuva yale PSU, ekhishwe kanye nePi 3 entsha (enezidingo ezinkulu zamandla kunamamodeli wangaphambilini) inikela ngo-5.1V ku-2.5A - inala cishe yimuphi umsebenzi wePi.
Ukuphepha kungenye into okufanele ucabangele lapha futhi. Ngemibiko eminingi yezimpahla ezingavumelekile nezingavunyelwe ukukhishwa, ukusebenzisa i-PSU esemthethweni kukunika ukuqiniseka ukuthi umkhiqizo wekhwalithi.
Ukunikezwa okusemthethweni kwenziwa e-United Kingdom ngokukhiqiza amandla kagesi eStronics, etholakalayo kokubili emhlophe nomnyama, futhi itholakala ku-£ 7 / $ 9.

I-PC USB Amandla
Uyazi ukuthi ungakwazi yini ukwenza amanye ama-raspberry Pi amamodeli ngqo kusuka ku-PC noma i-laptop yakho?
Akuwona umthombo ophelele wamandla njengoba ikhompyutha ye-USB ye-port ingashintsha kakhulu, futhi-ke, noma yikuphi i-hardware enamathiselwe nayo izokhipha kulo mthombo wamandla, kodwa ingenza umsebenzi kwezinye izimo.
Uma usebenzisa imodeli yamandla aphansi njengePi Zero ethandwayo ngokuzijwayela okulula, ikhodi ye-laptop ye-laptop ingaba yinkosi yokuzikhethela - ikakhulukazi uma iphuma ngaphandle.
Zama bese ubone ukuthi uthola kanjani - kuyindlela engabizi lapha!

AmaHhobhu wokushaja
Ngokufanayo ne-PC USB port, ihabhu lokushaja ingaba isisombululo esikahle esheshayo sedeskithophu se-Raspberry Pi yakho.
Ngamamodeli wakamuva anikeza u-5V ku-12A +, i-Pi yakho akufanele ibe nezinkinga zokuhambisana nanoma yini oyiphonsa kuyo. Nakuba lokho kuzwakala kuhlaba umxhwele, Kuyafaneleka ukucabangela ukuthi leli gunya likwabelwana kuwo wonke amachweba.
Inombolo ekhulayo yezabhu zokushaja ze-USB iyatholakala kulokho okubonakala sengathi imakethe ekhulayo ngenxa yenani lamadivayisi esisebenzisa nsuku zonke.
Amanani ahlukahluka kuye ngamandla nenombolo yamapayipi - isibonelo esibonisiwe ngu-Anker's PowerPort 6 esibheke cishe angu-£ 28 / $ 36. Okuningi "

Amabhethri weLiPo
I-lithimu Polymer (LiPo) amabhethri athola ukuthandwa kakhulu eminyakeni yamuva ngenxa yezici zabo ezikhangayo nobukhulu obukhulu.
Ukugcina amazinga omthamo ngokulinganisela nokugcina izimboni zamandla kuleso sinyathelo esincane kwenza i-LiPo ibe umthombo ophelele wamandla kumaphrojekthi e-Raspberry Pi eselula.
Ukuze wenze lokhu kube lula nakakhulu, i-Pi superstore uPimoroni entsha yakha ibhodi elincane nelingabizi kakhulu okufanele lixhumane namabhethri akho e-LiPo, okwenza amandla i-pi nge-PIN ye-GPIO.
I-ZeroLipo ifinyelela ngo-£ 10 / $ 13 kuphela futhi ihlanganisa izinkomba zamandla / amabhethri aphansi, izinketho ze-GPIO zokuxwayisa, nesici sokuvala ukuphepha ukuvikela amabhethri akho. Okuningi "

Spare amabhethri
Uma amabhethri e-LiPo ayengaphansi kwesabelomali sakho, kungani ungasebenzisi amabhethri okuphumula onayo ekhaya?
Uma unamabhethri omdala anesilinganiso esingenani esingu-6.2V ngaphansi komthwalo, ungawafakela ebhodini lokungeza 'le-MoPi' elinamandla ukuze usebenzise i-pi yakho.
I-MoPi ingasebenzisa noma yini kusuka kumabhethri omdala we-laptop kumaphakethe we-RC angadingeki, nge-smart UI yokucushwa ithuluzi lokukulungisela noma yiliphi ikhemikhali yebhethri onquma ukuyisebenzisa.
Ingasetshenziswa futhi njengamandla okuphazamiseka okungaqinisekisiwe (UPS) ngokusebenzisa amaminithi namabhethri ngasikhathi sinye, kanye nokufaka ukuvikeleka okuphezulu kwamanje, ama-LED okubonisa, nokuphakanyiswa kwesimanje.
I-MoPi itholakala ku-£ 25 / $ 32. Okuningi "

Amandla weSolar
Uma uhlala endaweni ethile kancane kunesiqhingi sasekhaya saseBrithani, ungase ukwazi ukusebenzisa imisebe yelanga bese ujova amandla athile welanga emaphrojekthi akho.
Amapaneli amancane asebusuku avulekile eminyakeni yamuva njengoba ukunyakaza komenzi kususiwe, kusishiye abathengi banamanani amaningi namasayizi okukhetha kuwo.
Kunezindlela eziningi zokufeza amandla we-solar kumaphrojekthi akho. Indlela eyisisekelo kunazo zonke ukumane ulayishe amabhethri ngephaneli yelanga bese uwaxhuma ku-Pi yakho.
I-Adafruit Industries yenza imikhiqizo emibili enhle ukukusiza ukuthi wenze lokhu - ibhodi yeshaja ye-USB, ne-6V 3.4W iphaneli yelanga.
I-setups ezithuthukisiwe ezingaphezulu nazo kungenzeka, ikuvumela ukuba ushintshe njalo i-Pi 24/7 exhunyiwe. Okuningi "

I-Boost Converter ne-AA Batteries
Enye inketho eshibhile futhi elula ukusebenzisa i-converter yokukhuphula ngamabhethri AA atholakalayo kalula. Lawa ayaziwa nangokuthi 'isinyathelo-up' noma 'DC-DC power' converters.
Ukugqugquzela abaguquleli bathatha umthamo ophansi, isibonelo, 2.4V kusuka kubhethri e-AA elayishwayo engu-2x, futhi 'kukhuthaza' lokhu kufike ku-5V. Nakuba lokhu kuza ngezindleko zamanje kwebhethri yakho, kungasebenza kahle nge-Raspberry Pi engaxhunyiwe kunoma yikuphi ihadi elilamandla.
Ukugqugquzela abaguquguquli babe nokusetha okulula ngezingcingo ezimbili kuphela (ezihle futhi ezingalungile) kanye nezintambo ezimbili eziphuma (ezihle futhi ezimbi). Isibonelo esihle sekhwalithi ngu-Adafruit's PowerBoost 1000, enikeza u-5V ku-1A kusuka kumabhethri emithombo enikela ngezansi njenge-1.8V. Okuningi "

Amabhange Amandla
Uma ungumgibeli njengami, cishe uzoba nesisombululo samandla eselula ukuze uthole ifoni yakho ngosuku olude.
Leli bhange lamandla elingu-5V lingasetshenziswa futhi ukugunyaza i-Pi yakho, okwenza kube isisombululo samandla eselula esiphephile futhi esingabizi ngamaphrojekthi akho.
Bheka ama robotshi amaningi aseRispberry Pi futhi cishe uyayibona eyodwa isetshenziswa. Isisindo sabo esilinganisako nesayizi encane kakhulu kubenza kube ngcono kumaphrojekthi we-robotics, ngenzuzo eyengeziwe yokuthi kulula ukukhokha.
Bheka izinketho ezincane ezingathengi ezifana ne-Anker PowerCore + Mini, ezithengisa u-£ 11 / $ 14. Okuningi "

Amandla ngaphezu kwe-Ethernet (i-PoE)
Indlela enhle yokunika amandla i-Pix Raspberry Pi endaweni engafanelekile ukusebenzisa amandla phezu kwe-Ethernet (i-PoE).
Ubuchwepheshe obusithakazelisayo busebenzisa ikhebula elijwayelekile le-Ethernet ukuthumela amandla ebhodini eliyingxenye elikhethekile elifakwe ku-Raspberry Pi yakho. Inenzuzo eyengeziwe yokuxhuma i-Pi yakho kwi-inthanethi ngesikhathi esifanayo, usebenzisa i-'jectject 'ekhethekile.
I-injector ihlanganisa uxhumano lwe-Ethernet kusuka ku-router yakho ngamandla avela kwodokodo lwodonga, luthumela phansi ikhebula elijwayelekile le-Ethernet ekungeneni kwe-Pi, bese lihlukanisa nalokhu.
Nakuba izindleko zokusetha zingase zibe enye yezindawo eziphakeme kakhulu lapha, kuyisisombululo esihle ngempela samaphrojekthi afana ne-Pi CCTV enzima ukufika kanye / noma engekho eduze kwesikhwama esivamile.
Esinye sezibonelo ezihamba phambili ngu-PiSupply's PoE Switch HAT, etholakalayo nge-£ 30 / $ 39. Okuningi "

Ukunikezwa Kwamandla Okungaphenduki
Uma kukhona into eyodwa i-Pi ihle, iyinto encane! Leyo nyathelo encane iyazibophezela kahle kumaphrojekthi eselula, noma ngabe amandla eselula kufanele aphume ngesikhathi esithile.
Uma kwenzeka, lokhu kuvame ukusho ukuvala iphrojekthi yakho, ukushaja amabhethri nokuqala futhi.
Enye indlela ezungeze lokhu ukusebenzisa i-Power Supply Engaphenduki (UPS). I-UPS ibaluleke kakhulu ibhethri encane ehlangene nomjikelezo ohlakaniphile namandla ajwayelekile amandla.
Amandla amandla agijima kuPi bese efaka ibhethri, futhi uma lokho kukhonjisiwe (ngezinhloso noma ngephutha) ibhethri ithatha, ukuqinisekisa ukuthi amandla akho angeke angaphazamiseka (ngakho igama).
Kukhishwe amabhodi amaningana we-UPS ambalwa-ahlukile, kufaka phakathi i-Pics UPS kusuka ku-PiModules, i-MoPi (evezwe kulolu hlu kakade) nePiSupply PiJuice. Amanani aqala ukusuka ku-£ 25 / $ 32. Okuningi "
