2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

REAL yog cov nyiaj hauv tebchaws Brazil txij li xyoo 1994 thiab rau kev ua koob tsheej nco txog nws lub hnub nyoog 25 xyoos, xyoo tas los (2019) Casa da Moeda (brazilian mint) tau ua kev nco txog 1 REAL npib nrog hummingbird nyob rau hauv obverse (tsis zoo li niaj hnub zoo nkauj ntawm cov koom pheej).

Hummingbird yog daim duab ntawm 1 REAL daim nqi thaum cov txiaj ntsig tau pib 25 yers dhau los. Daim 1 REAL nqi tsis raug tsim tawm lawm.

Raws li tus lej txaus siab, Kuv tau siv RaspberryPi 2 qub, TFT LCD Zaub thiab qee qhov chaws hauv JavaScript los ua lub moos uas qhia lub sijhawm nrog cov nqi thiab npib ntawm tsev neeg thib ob ntawm REAL. Nws yog lub khoos phis tawj tiag tiag uas ua raws li lub moos.

Koj tuaj yeem hloov cov ntaub ntawv-j.webp

Khoom siv

- Raspberry Pi board

-TFT 3.5 `` LCD

-Ntoo lub thawv

Kauj Ruam 1: Npaj Lub Thawv

Kuv muaj lub thawv ntoo qub no nyob ib puag ncig ntev, Kuv xav tias nws tau siv los khaws teabags. Kuv "tsoo" lub vaj huam sib luag pem hauv ntej thiab ua lub qhov square nrog Dremel cov cuab yeej kom haum rau 3, 5 '' zaub.

Tom qab rub tag nrho cov khoom sib txuas Kuv yuav lo daim thim rov qab.

Cov zaub yog kub rau lub vaj huam sib luag.

Kauj ruam 2: Coding

Lub luag haujlwm ntawm RaspberryPi hauv txoj haujlwm no yog los tso saib lub vev xaib ntawm Chrome hauv hom puv npo.

Piv txwv li yog tias lub sijhawm yog 3:05, nws yuav qhia 2 daim nqi tiag thiab 1 npib tiag rau lub sijhawm, thiab 5 xees npib rau feeb.

Kuv tau ua nplooj ntawv tiag los sim ntawm qhov txuas https://numismaticclock.freetzi.com, tab sis hauv txoj haujlwm nws yuav ua haujlwm hauv zos.

Nws yog nplooj ntawv HTML nrog qee qhov JavaScript los kho nplooj ntawv tshiab thaum ib feeb dhau los. Txoj haujlwm muaj 13 cov duab los teev sijhawm (0h thiab 12h yog tib cov duab tab sis cov ntaub ntawv sib txawv) thiab 60 cov duab los qhia feeb. Cov ntaub ntawv HTML (index.html) thiab 73-j.webp

Tsab ntawv sau cov ntawv cim kom pom cov duab txhua lub sijhawm nplooj ntawv raug rub tawm. Qhov sib txawv tau txais qhov tseeb feeb ntawm qhov system sab nraum lub sijhawm ua haujlwm thaum lwm qhov sib txawv tau txais nws sab hauv. Txhua qhov thib ob, ob qhov kev hloov pauv tau muab sib piv, thiab yog tias lawv sib txawv nws txhais tau tias ib feeb dhau los, yog li nplooj ntawv tau rov ua dua tshiab.

Kauj Ruam 3: Teeb Duab Raspbian Txoj Cai

Ua ntej tshaj plaws, koj yuav tsum rub tawm cov duab Raspbian tshwj xeeb uas ua haujlwm nrog koj cov zaub. Hauv kuv qhov xwm txheej, kuv cov zaub yog KeDei 6.2 version, yog li kuv rub lub distro los ntawm

Koj yuav xav tau software uas hu ua WinDisk32Imager txhawm rau hlawv cov duab ntawm daim npav SD thiab tom qab ntawd, khau raj koj lub rooj tsavxwm.

Kauj Ruam 4: Hloov Cov Ntaub Ntawv mus rau Pawg Thawj Coj

Cov ntsiab lus ntawm cov ntaub ntawv relogio.rar (Kauj Ruam 3) yuav tsum tau xa mus rau RaspberryPi.

Koj tuaj yeem siv pendrive ua lossis tuaj yeem ua nws los ntawm SSH nrog software uas hu ua WinSCP. Muab tag nrho cov ntaub ntawv tso rau hauv daim nplaub tshev sab hauv/tsev/pi/

Txoj hauv kev ntawm cov ntaub ntawv index.html yuav yog ~/home/pi/relogio/index.html

Kuv pom zoo siv Putty kom yooj yim dua los teeb tsa tom ntej.

Kauj ruam 5: Teeb Linux Parameters

Txog tam sim no, cov ntaub ntawv raug khaws tseg ntawm koj lub rooj tsavxwm thiab koj tuaj yeem txuas cov keyboard, qhib tus navigator thiab ntaus /home/pi/relogio/index.html hauv qhov chaw nyob. Nws yuav tso saib lub moos nplooj ntawv, tom qab ntawd nias F11 kom nkag mus rau hom puv npo thiab nws ua tiav!

Tab sis peb tuaj yeem ua kom nws zoo dua.

Koj tuaj yeem rub tawm software uas zais tus cursor nas thaum nws tsis siv.

sudo apt-tau nruab unclutter

Thaum nws ua tiav, koj ntaus cov lus txib hauv qab no kom nkaum tus cursor yog tias nws tsis txav mus rau 2 vib nas this:

sudo unclutter -idle 2 -hauv paus

Chrome browser tuaj yeem qhib los ntawm kab hais kom ua hauv hom puv npo thiab ncaj qha rau nplooj ntawv moos (tsis txhob siv sudo int nws cov lus txib):

chromium-browser --homepage /home/pi/relogio/index.html-pib-puv npo

Peb tuaj yeem ua kom nws zoo dua.

Peb yuav teeb tsa lub npe tsis tseeb, piv txwv li, nrog ib lo lus txib peb yuav ua haujlwm software los nkaum tus cursor thiab qhib Chrome ntawm nplooj ntawv moos.

Txhawm rau ua qhov no, ntaus cov lus txib hauv qab no:

sudo nano /home/pi/.bashrc

Nyob ze ntawm "Alias txhais" ntu, ntxig cov ntawv hauv qab no (ib yam li cov duab):

alias relogio = 'chromium-browser --homepage /home/pi/relogio/index.html-pib-puv npo | sudo unclutter -idle 2 -hauv paus & '

Kaw thiab rov qhib koj lub davhlau ya nyob twg lossis hom:

qhov chaw /home/pi/.bashrc

Tam sim no thaum koj ntaus qhov hais kom ua relogio ntawm lub davhlau ya nyob twg, nws yuav cia li khiav qhov software tsis sib dhos thiab qhib Chrome.

Kauj Ruam 6: Muab Cov Khoom Siv

RasbperryPi Kuv siv hauv txoj haujlwm no tau hnyav heev. Tsuas yog ob lub USB chaw nres nkoj tseem ua haujlwm thiab kuv txuas lawv nrog cov dhia kom muab nws tso rau hauv te tom qab ntawm lub thawv. Kuv kuj tau txuas ntxiv los ntawm PP1 thiab PP2 cov kab laug sab ntawm lub rooj tsavxwm mus rau lub zog txuas.

Kuj tseem muaj lwm lub qhov square ont nws sab laug rau lub ethernet txuas.

Kauj Ruam 7: Tiav Lub Thawv

Kuv txiav qee cov popsicle sticks los ua tus thav duab nyob ib ncig ntawm lub vijtsam txhawm rau zais qee qhov tsis zoo.

Kuv tuaj yeem yooj yim glued lub vaj huam sib luag pem hauv ntej rov qab rau hauv lub thawv. Tsis tas li glued cov hlau nplaum los tuav lub npib nco txog saum lub vijtsam.

Kauj Ruam 8: Txaus Siab Rau Koj Cov Numismatic Moos

Lub thawv muaj qhov chaw tuav lub txhab nyiaj hluav taws xob sab hauv, yog tias koj siv lub dongle rau wifi (lossis tshiab dua ntawm lub rooj tsavxwm) nws yuav ua rau nws tsis muaj wireless.

Kauj Ruam 9: Txaus Siab Rau Koj Lub Minicomputer

Nws tuaj yeem siv ua lub khoos phis tawj ib txwm muaj, khiav lub server khaws cia piv txwv.

Kuv vam tias koj txaus siab thiab nws tuaj yeem pab tau hauv cov haujlwm zoo sib xws.

PS. Thov txim rau cov keyboard qias neeg:)
