Lub hom phiaj ntawm txoj haujlwm no yog txhawm rau tsim hluav taws xob Braille system uas muaj nqis thiab tuaj yeem ua cov thev naus laus zis no rau txhua tus. Tom qab kev tshuaj xyuas thawj zaug, nws tau pom meej tias yog li tsim tus yam ntxwv ntawm tus kheej yuav tsum ua tau raws qee qhov xav tau yam tsawg kawg nkaus:

• yuav tsum siv ntau qhov uas twb muaj nyob hauv khw
• yuav tsum tau suav nrog qhov qis tshaj suav suav tau
• qhov kev cai yuav tsum yooj yim rau cov qauv, yooj yim kom nce (txhaj tshuaj molding)
• lub zog yuav tsum tsis tas yuav tsum ua kom lub xeev tus pin

Tom qab ua haujlwm ntawm ntau qhov rov ua dua, Kuv tau tsim tus cim Braille hluav taws xob nrog lub tshuab nqus hlau sib nqus uas muaj qhov suav tsawg tsawg, yooj yim rau kev tsim dua lossis nce rau kev tsim khoom!

Txoj haujlwm no tau pab nyiaj rau tus kheej, thiab kuv txiav txim siab tsis ua daim ntawv pov thawj no vim kuv xav pom ntau tus neeg kom tau txais txiaj ntsig los ntawm nws.

Nws ua haujlwm li cas? Nrog rau kev tsim qauv tam sim no, txhua qhov "dot" ntawm tus yam ntxwv ua los ntawm 2 3D luam tawm ntu (Lub cev thiab tus tuav hlau nplaum), 2 M2 txiv ntoo, 2 hlau nplaum, thiab 0.1 hli xaim xaim. Kev tswj hwm PCB kuj tuav lub cev. Qhov kev tsim qauv no suav qhov feem tsawg tsawg, thiab tau siv zog los siv cov khoom uas twb muaj lawm, xws li M2 hlau txiv ntseej; qhov kev tsim no tso cai rau tus nqi qis heev rau ib tus cim.

A (tsis hais meej) kev txheeb xyuas tus nqi Tus nqi rau ib tus pin, rau kev tsim khoom raws li ntau pua tus, kwv yees nyob ib puag ncig lossis tsawg dua 0.85 €. Nws suav nrog cov txiv ntoo, 2 qhov chaw txhaj tshuaj pwm (tus tuav hlau nplaum thiab lub cev), cov hlau nplaum, thiab cov kauj. Tus nqi rau ib tus xeeb ceem yog li ntawm 5/6 € ib tus cim, nrog rau kev tsim khoom me me/nruab nrab. Tus nqi rau tag nrho kab ntawm 10 tus cim nyob ib puag ncig 120 €, suav nrog 60 € ntawm cov cim thiab 60 € ntawm pcb, feem ntau nws vim yog TB6612 tam sim no siv uas kim heev. Ib qho cuab yeej cuab tam nrog 8 kab, pawg tswj hwm, ntsuas hluav taws xob, roj teeb thiab lub thawv ntim khoom yuav tsum muaj tus nqi tag nrho tsawg dua 1000 € rau qhov nruab nrab/tsim khoom me me, tso cai tus nqi muag khoom zaum kawg ntawm zaum 2000 € … uas yog qhov tsis zoo piv rau cov khoom lag luam muaj nyob rau niaj hnub no!

Khoom siv

2 × M2 Hlau Txiv Ntoo Ib M2 hlau txiv ntoo yog siv los ua kom yooj yim kom tau txais, tus nqi qis rau kev tuav tuav

2 × 2mm dia, 2mm siab hlau nplaum Lawv tau tso rau hauv tus tuav hlau nplaum

Kauj ruam 2: Cov lus qhia

Kauj Ruam 1 3D Luam lub cev thiab tus tuav lub cev Lub cev thiab cov hlau nplaum tuav cov ntaub ntawv muaj nyob hauv STL cov ntaub ntawv hom thiab tuaj yeem luam tawm nrog lub tshuab luam ntawv 3D-based. Ib feem tuab tau qis dua 0.3mm hauv qee cov ntsiab lus, tab sis nws tseem tuaj yeem luam tawm, thiab tom qab UV kho qhov ib feem yog qhov muaj zog txaus.

Kauj Ruam 2 Sib dhos cov tuav hlau nplaum Thaum koj tau luam tawm 3D cov ntu, nws yog qhov tsim nyog los sib sau ua ke. Cov vis dis aus no qhia yuav ua li cas cov khoom sib txawv ntawm ib tus pin tau sib sau ua ke rau cov qauv tam sim no.

Kauj Ruam 3 Coil winding Kuv tau teeb tsa lub tshuab yooj yim kom siv lub tshuab ua kom tsis siv neeg. Nws yog tswj los ntawm Arduino.

Kauj Ruam 4 Sib Sau Tus Cwj Pwm CharacterBPC Thaum koj tau sib sau ua ke 6 tus pin, nws yog lub sijhawm los ntxig lawv rau hauv tus cwj pwm PCB thiab muab tshuaj txhuam rau lawv.

Kauj Ruam 3: Xeem BrailleShield Demo Board

Txhawm rau kom muaj peev xwm ntsuas tus lej Braille sai, kuv tau tsim lub rooj sib tham demo, uas yuav tsum muaj txiaj ntsig zoo los nthuav tawm txoj haujlwm rau cov neeg siv khoom muaj peev xwm. Pawg thawj coj no tau tsim los ua Arduino shield, 12v siv, siv 3 TB6612 ICs los tsav cov coils. Nws muaj lub pob kom xaiv cov qauv qhia, thiab qhov chaw rau 128x64 Oled uas yuav tso tawm tsab ntawv uas sib haum rau tsab ntawv Braille uas pom los ntawm tus pin.

Dav dawb hau tsim cov ntaub ntawv muaj.

Kauj Ruam 4: Cov Ntsiab Lus rau Braille Tablet Nrog Chaw Nres Nkoj thiab Tshuab Luam Ntawv

Ob leeg muaj rau rub tawm ua Solidworks sib dhos. Lub tshuab luam ntawv tau ua kom zoo heev thiab nrog qee qhov kev kho kom zoo yog npaj rau kev tsim qauv. Nws yeej qhov khoom plig pab lossis nrhiav tus pab txhawb nqa yuav zoo tshaj! Txog tam sim no txhua qhov haujlwm tau txais nyiaj los ntawm tus kheej thiab nws tau siv sijhawm ntev heev, yog li qee qhov peev nyiaj yuav tsim nyog rau txoj haujlwm no txuas ntxiv mus …

Kauj Ruam 5: MOLBED Kuaj thiab Ntau Cov Lus Teb

Thaum lub rooj sib tham nrog koom nrog rau cov neeg dig muag hauv tebchaws Ltalis, MOLBED tau raug sim thiab peb tau txais ntau cov lus tawm tswv yim, uas yuav yog qhov tseem ceeb heev rau kev tsim cov khoom lag luam uas haum rau lawv cov kev xav tau.

Nov yog cov npe luv ntawm lawv cov lus pom zoo / xav tau:

• Ntau kab tsis tseem ceeb raws li ib tus neeg xav tau;
• tus txheej txheem loj Braille cell dimension, ntawm qhov tod tes, xav tau ntau dua kom tau txais kev nyeem nrawm dua.
• Tus cwj pwm MOLBED tuaj yeem rov teeb tsa kom zoo ib yam, lossis qhov chaw me ntsis ntev dua, tab sis muaj tib tus pin loj thiab nrug deb li tus qauv (kim) Braille cells;
• Kev koom ua ib lub tshuab luam ntawv Braille ntawm lub chaw nres tsheb tuaj yeem yog qhov nthuav heev;
• Yuav muaj peev xwm los pab nyiaj rau cov phiaj xwm no yuav nyuaj rau tam sim no "lub xeev ntawm yam", tsawg kawg hauv lub tebchaws no, txawm tias lawv lees paub tias txoj haujlwm no yeej muaj peev xwm heev. Yog li tam sim no qhov kev sib tw no tseem yog lub sijhawm zoo tshaj plaws rau txoj haujlwm no txuas ntxiv thiab muab cov neeg no tus nqi qis rau lwm txoj hauv kev rau cov khoom lag luam kim, thiab qhov ntawd tuaj yeem ua tau raws li qhov lawv xav tau!
