Nov yog ib qho ntawm cov tswv yim vwm uas tsuas yog ntog hauv kuv lub hlwb. Kuv xav, yuav tsis zoo yog tias muaj khob kas fes uas koj tuaj yeem hloov kho ntawm yoov? Ib qho uas zoo li zoo li lub khob kas fes zoo tib yam. Kuv tau tshawb nrhiav thiab pom tsuas yog ib qho piv txwv ntawm qee yam zoo sib xws, tab sis nws tsis zoo li lub khob kas fes ib txwm muaj thiab cov zaub tau tiaj tus.
Qhov tseem ceeb tshaj plaws ntawm e-ink / e-ntawv qhia yog tias lawv tuaj yeem hloov pauv tau, ntxiv rau tsis xav tau lub zog los tuav cov duab. e-ink qhia pom feem ntau hauv ebook nyeem ntawv, tab sis kuv xav tias vim li cas ho tsis ua khob nrog cov zaub uas nkhaus rau lub khob? Kuv pom qhov pheej yig e-ink zaub uas yuav haum rau daim nqi (qhov tseeb tsuas yog hloov pauv tau uas kuv tuaj yeem pom kev yuav los ntawm kev tuag ib leeg xwb) thiab yog li kuv tau teeb tsa los tsim kuv lub zeem muag.
Kauj Ruam 1: Qhov Chaw
Kev faib ua feem yog ncaj nraim rau pem hauv ntej. Cov khoom siv yoj yoj yoog tau hloov pauv e-ink tsuas yog ib qho kuv tuaj yeem pom, thiab nws muaj yooj yim ntawm ebay lossis aliexpress. Kuv xaiv ESP32 Lolin Lite rau lub microcontroller vim tias nws pheej yig (zoo nkauj ib yam kuv tau txais yog clone) tab sis muaj Bluetooth LE ntxiv rau LiPo lub roj teeb them thiab txaus cia rau fonts thiab bitmaps rau cov zaub.
Ib qho nyuaj rau nrhiav cov khoom yog lub khob haum kom haum cov khoom siv hluav taws xob. Kuv nrhiav tsis tau dab tsi tiag. Thaum xub thawj, Kuv tau npaj yuav siv cov iav "Kuv tsis yog ntawv khob" khob, thiab khoov ib daim ntawv acrylic nyob ib puag ncig nws. Txij li lub khob tau muab sib dhos thiab cov ntawv raj acrylic yuav ncaj, yuav muaj chaw txaus nyob ze rau hauv qab kom haum rau ntu. Kuv tsis muaj hmoo ntau nrog acrylic khoov tab sis.
Tom qab ntawd kuv nco tau ntau xyoo dhau los kuv cov menyuam tau ua mugs nrog cov khw yuav khoom. Kuv mus nrhiav qhov ntawd thiab pom cov chaw uas siv los muag lawv tsis tau ua dua, txog thaum kuv pom tias Hobby Lobby tseem muag lawv. Lawv pheej yig, hauv txhua txoj kev. Tab sis rau qis dua $ 1 nws ua haujlwm tau zoo, tsuas yog muaj chaw txaus kom haum txhua qhov hauv.

Kauj Ruam 2: Ntxig Daim Ntawv thiab Cov Ntawv Qhia Txog Lub Hauv Paus
Vim hais tias lub khob tau meej thiab koj tsis xav pom cov khoom siv hluav taws xob, luam tawm qhov ntxig thiab ua tib zoo txiav nws nrog rab chais hniav lossis txiab. Vim tias e-ink zaub tsis yog ntawv dawb, qhov ntxig muaj lub teeb grey qauv ntawm nws uas zoo nkauj zoo sib xws nrog cov xim tom qab ntawm e-ink zaub. Txiav tawm lub duab plaub rau cov zaub kom pom los ntawm. Muab lub qhov tso rau hauv lub khob kom ntseeg tau tias nws haum, thiab txiav txim siab sab twg ntawm lub khob koj xav kom cov zaub tso rau.
Tsis tas li ntawm daim ntawv no yog lub voj voos uas koj tuaj yeem siv los txiav cov duab los qhia hauv paus. Kuv siv daim ntawv corrugated nyias los ntawm lub thawv me me.
Cov duab los qhia ntawv no nrog ua haujlwm txhawm rau txhim kho cov khoom siv hluav taws xob rau, thiab tuav cov ntawv ntxig rau lub khob hauv qab.
Kauj Ruam 3: Mount Electronics rau Base
Kuv tau siv lub taub hau kaum sab xis rau ESP32 thiab tsuas yog rau tus pin kuv xav tau. Tshwj xeeb qhov no yuav tso chaw nyob ntawm ib sab rau lub roj teeb LiPo me me. Txuas cov xov hlau los ntawm txoj hlua khi uas muab nrog lub e-ink zaub lub kaus mom raws li qhia. Tom qab ntawd, nrog ESP32 nyob hauv nruab nrab thiab nyob nrog USP thiab lub roj teeb txuas ze rau ntawm ntug raws li koj tuaj yeem tau txais, nias qis kom lub taub hau pins txhawm rau sab saum toj ntawm daim duab los qhia.
Txuas rau hauv JST lub roj teeb txuas thiab siv qee daim kab xev ob tog los lo lub roj teeb nyob ib sab ntawm ESP32. Ceev faj tsis txhob tso lub roj teeb ntau dhau vim tias lawv muag muag.
Txuas lub xaim hlua rau hauv lub e-ink tsav tsheb lub kaus mom, thiab sim nkhaus cov xov hlau nyob ib ncig ntawm tus poj niam lub taub hau kab txaij thiab hla saum lub rooj tsavxwm. Ruaj nws nrog qee daim kab xev. Ua kom ntseeg tau tias cov hlua txuas tau txuas nrog, thiab tso lub kaus mom hla ESP32 kom deb li deb nws yuav mus yam tsis tau hla ntawm lub voj voos duab kab ntawv, thiab qhia txoj hlua khi tom qab JST lub roj teeb txuas thiab USB chaw nres nkoj. Ruaj ntseg nrog daim kab xev ntau dua.
Nov yog qhov nyuaj tab sis cov xov hlau zoo li mus qhov twg lawv xav tau mus, thiab txhua yam haum ua ke zoo nkauj.
Kauj Ruam 4: Them Chaw Nres Nkoj
Koj yuav xav kom muaj peev xwm them koj lub khob thiab tseem ua haujlwm rau nws, yog li koj yuav tsum tso cov thawv ntawv hluav taws xob sib dhos rau hauv lub khob thiab nco ntsoov qhov chaw nres nkoj USB nyob qhov twg. Kos ib lub xwmfab loj txaus rau koj lub xovtooj kom haum (Kuv muab tso ze rau ntawm lub hauv paus ntawm tus tes tuav kom nws yuav tsis pom thaum tuav lub khob), thiab tom qab ntawd txiav tawm lub qhov. Kuv siv 3/16 laum ntawm ob sab thiab tom qab ntawd txiav tawm qhov nrog x-acto hniav.
Muab lub rooj sib dhos tso rau hauv lub khob dua thiab kuaj seb koj lub xov tooj puas tuaj yeem haum thiab txuas tau.
Kauj Ruam 5: Rooj Sib Tham Kawg
Tshem lub hauv paus los ua ke dua, thiab tom qab ntawd ntxig daim ntawv lo. Nco ntsoov tias nws tau nthuav tawm sab hauv lub khob thiab tom qab ntawd kaw cov ntug kom khaws cov duab. Txuas lub e-ink zaub rau lub rooj sib txuas me me, thiab pawg thawj coj saib mus rau txoj hlua los ntawm lub kaus mom. Ua tib zoo xaub lub hauv paus sib dhos rau hauv lub khob, taw qhia USB chaw nres nkoj mus rau lub qhov hauv lub khob thiab thawb nws mus rau hauv qab ntawm lub khob. Ib zaug ntxiv kom ntseeg tau tias koj tuaj yeem ntsaws koj lub USB cable rau hauv lub rooj tsavxwm.
Tam sim no nruab nrab e-ink zaub rau hauv kev txiav tawm ntawm daim ntawv kab ntawv. Xyuas kom tseeb tias nws yog qib, thiab nias tag nrho txoj kev mus rau qhov nkhaus ntawm lub khob. Siv qee daim kab xev los tuav nws hauv qhov chaw. Kuv tau ntxiv ib daim ntawv thim rov qab los pab tuav lub e-ink zaub hauv qhov chaw. Koj yuav tsum tau kaw cov kab xev rau kab ntawv, thiab koj yuav tsum ua ib qho 45 degree quav hauv kab ntawv kom nws mus ntawm kab rov tav mus rau ntsug, nqes mus rau hauv paus.
Tam sim no koj yuav tsum muaj peev xwm tso lub khob sab hauv tso rau hauv lub khob.
Kauj Ruam 6: Rwb thaiv tsev
Vim tias lub khob yog yas yas nws yuav luag tsis muaj rwb thaiv tsev. Cov duab e-ink kuv pom yog rhiab rau cua sov, yog li cov cua sov los ntawm lub khob kas fes raug txaus kom ua rau cov zaub ploj mus. Kuv ntxiv qee qhov rwb thaiv tsev nyob ib ncig ntawm lub khob los ntawm kev txiav hauv qab tawm ib lub khob zoo li qub thiab tom qab ntawd qhwv nws ib ncig ntawm lub khob ntxig, txiav tawm cov npuas ntau dhau. Nws kuj tseem xav tau qhov txiav rau hauv nws txhawm rau kom haum ib puag ncig lub rooj sib txuas me me.
Qhov no tau pab ntau yam. Thiab tau kawg nws tseem txhais tau tias koj cov kas fes nyob ntev dua.
Kauj ruam 7: Programming
Kuv tau muab cov cai ntawm GitHub rau kev ua haujlwm ESP32. Kuv tab tom siv Atom editor nrog PlatformIO txuas ntxiv teeb tsa. Txoj cai yog siv Arduino moj khaum nrog espressif32 platform, siv Adafruit GFX Library los ntawm Adafruit los muab cov ntawv sau rau ntawm lub vijtsam. Kuv npaj yuav ntxiv cov duab nrog rau kev sib txuas Bluetooth, siv nrog lub xov tooj ntawm tes kom hloov kho cov duab thiab ntawv. Txog tam sim no, muaj ntau cov ntawv txaus luag qhia nws mus los.
Kuv tau sim ua kom lub zog siv hluav taws xob tsawg li sai tau tab sis kuv xav tias nws tsis zoo li qhov ua tau. Tseem, nws kav ntev ob peb teev thaum hloov pauv cov duab txhua 10 vib nas this lossis ntau dua.
Cov cai yog me ntsis ntxhi! Muaj cov khoom nyob rau ntawd rau kev siv BLE kev sib txuas lus uas tseem tsis tau ua tiav. Kuj tseem muaj qee txoj cai txhawm rau sib txuas lus mus rau Slack Bot, lub hom phiaj cia kuv cov neeg ua haujlwm sib tham xa ntawv mus rau lub khob ntawm lub sijhawm tiag tiag los ntawm peb lub tuam txhab Slack chav sib tham. Thaum txhua qhov no ua haujlwm lub khob yuav yog IOT (Internet ntawm yam khoom)!
Qhov Code
Kauj Ruam 8: Siv Nws
Coj Cov Khob Zaub rau hauv koj lub tuam txhab kev sib tham tom ntej. Haus kas fes. Tos kom cov neeg ua haujlwm pom … txaus siab!
