Txoj haujlwm no tau tsim los rau txoj haujlwm thaum kuv tseem kawm ntawv theem siab hauv kuv qib 11 Kev Sib Txuas Lus Technology. Lub hom phiaj tau ua kom muaj tswv yim caw rau txhua qhov xwm txheej koj xav tau xws li hnub yug, tshoob kos, tog, thiab lwm yam.

Txoj kev uas peb tus kws qhia piav qhia txog txoj haujlwm zoo li nws tau thawb tiag tiag tias qhov kev caw yuav tsum sawv tawm los suav tias yog txoj haujlwm zoo. Los ntawm qhov kev xav ntawd, Kuv xav tias kuv yuav tsum tau ua qee yam nrog lub vijtsam hauv nws kom ua rau cov neeg coob coob thiaj li hais tau. Txij li xyoo ntawd kuv tsis ntev los no tau sib cais ib lub ntsiav tshuaj los ntawm Tuam Tshoj uas tau nres ua haujlwm thiab khaws lub vijtsam; Kuv muaj lus teb tau rau tus hu.

Kauj Ruam 1: Nqi Khoom Siv (BOM)

• Lub thawv Project
• Kub nplaum
• HDMI Cable (nyiam dua)
• 7 "LCD Screen nrog 50 tus pin ribbon cable
• LVDS Driver Board
• 5.5*2.1 hli DC cable
• AA Roj teeb (x4) [txij li xyoo 18650s zoo nkauj heev/hnyav, tau sim plaub lub eneloop 1.2V AAs rau qhov ntsuas hluav taws xob zoo dua rau tus pi tab sis yuav tso tawm sai sai txawm tias ntawm 2000mah]
• Raspberry Pi Zero (lossis ib qho RasPi nyob ntawm qhov chaw seem hauv lub thawv)
• Quad AA Roj teeb lub thawv
• Thaum tshav kub kub ntsws tubing
• Poj niam HDMI rau Txiv neej mini HDMI adapter
• Hais lus 2W 8Ω (x2)
• Mercury/"Lub ntiajteb txawj nqus" hloov
• Class 10 8GB micro SD daim npav

• LM386 Audio Amp Board

*Yeem*

• HDMI rau mini HDMI cable (slim) hloov ntawm HDMI-HDMI cable thiab HDMI-mini HDMI Adapter
• Hall effect sensor hloov qhov hloov pauv mercury rau teeb meem kev nyab xeeb
• Breadboard rau kev sim
• RGB LCD HAT rau RasPi (hloov ntawm LVDS pawg tsav tsheb, txij li nrog qhov no tau ntxiv rau hauv kev ua lag luam yog lub zog tsawg dua xav tau thiab pheej yig dua li LVDS pawg thawj coj saib)

Kauj Ruam 2: Teeb Kho Raspberry Pi Zero Audio

(Koj tuaj yeem hla cov kauj ruam no yog tias koj siv Pi w/audio HAT lossis qauv nrog lub hli 3.5 hli)

Kuv tau pab teeb tsa lub suab thiab phau ntawv qhia kuv ua raws yog qhov no los ntawm Adafruit. Txog rau Raspberry Pi tus pib uas tsis muaj kev paub txog tus lej lossis cov khoom siv hluav taws xob/Circuit Court, nws yooj yim to taub thiab sau kom meej.

Kauj Ruam 3: Ua Yeeb Yam Caw Yeeb Yaj Kiab ntawm Pi

Tsis paub meej tias qhov txuas kuv tau ua raws rau cov kauj ruam no (raws li nws tau txog peb xyoos), tab sis qhov kev qhia no yuav tsum txaus: https://bit.ly/2JTk06K. Lub tswv yim dav yog tias thaum Pi khau raj, nws tshawb hauv txoj hauv kev ntawm koj cov ntaub ntawv video qhia tshwj xeeb thiab siv tus omxplayer yuam nws los ntawm qhov chaw nres nkoj HDMI.

Yav tom ntej kuv tuaj yeem sim rho tawm cov ntaub ntawv bash kuv siv los ntawm Pi nws tus kheej thiab tshaj tawm nws ntawm no yog tias koj hais mav ua teeb meem kho koj tus kheej cov ntaub ntawv bash. Tab sis nws kuj tseem vim tias cov ntawv txuas txuas yuav ua rau lub vis dis aus hloov chaw ua si ib zaug tom qab ntawd tso lub desktop duab qhib rau tus neeg caw tuaj saib thiab RSVP tau kawg.

Kauj ruam 4: Sib dhos

Txhawm rau rub txhua yam ua ke koj yuav xav tau cov hlau txuas thiab qee cov laug. Yog tias koj tsis tau soldered ua ntej ntawm no yog cov vis dis aus zoo kom koj mus. Qhov nyuaj tshaj plaws yog tej zaum haum txhua yam hauv lub thawv ntau dua li cov laug thiab sib dhos. Yog li thaum qhib lub thawv tsis txhob ntshai, cov vis dis aus yuav tshwm sim:)

Kauj Ruam 5: Qhov Kawg

Raws li koj tuaj yeem hnov hauv cov vis dis aus lub suab nrov zoo nkauj thiab tsis sib xws ntawm lub sijhawm. Yog vim li cas vim tias tsis muaj lub suab amp tau siv lub suab tau vam khom ntawm lub suab ntxiv uas tsim los ntawm Pi's GPIO yog li qhov tso tawm rau tus hais lus yog qhov tsawg. Yog li kuv tau nce lub suab ntawm daim vis dis aus ob zaug yog li qhov qis qis kuj tseem nce mus ntxiv, yog li qhov tawg tau hnov.

Cov vis dis aus yog nyem me ntsis txij li LVDS pawg thawj coj tsav tsheb tau noj <6V (cov roj teeb tsis yog qhov tshiab hauv daim vis dis aus).

Koj tau mus txog qhov kawg ntawm qhov kev lom zem no, ua tsaug rau koj lub sijhawm thiab mob siab rau qhov kev tsim no!
