Kev nthuav qhia

"La Picoreuse" yog qhov pheej yig (75 €), yooj yim los tsim A4 tus neeg kos duab paj ntaub.

Txoj haujlwm no lub hom phiaj los ua thawj kauj ruam lossis lub hauv paus rau kev xav rau lwm tus tsim khoom txhawm rau muab lwm txoj hauv kev rau kev lag luam kim heev embossers (3000 €)

Lub tswv yim ntawm txoj haujlwm no yog yug los teb rau cov kev xav tau ntawm ParACheval koom haum

Kev txiav thiab siv cov khoom siv tuaj yeem ua tsaug rau fablab-sud31 (Cintegabelle)

Kauj Ruam 3: Npaj Boards

Txiav ncej

Rub tawm 2 cov ntawv thiab txiav lawv siv lub tshuab txiav laser (cnc tuaj yeem tsoo qee qhov me me)

Qhov taw qhia laser txiav tshuab (100W laser txiav)

• rau 6mm MDF: 13m/s ntawm 80% lub zog
• rau 3 hli MDF: 30m/s ntawm 80% lub zog

Yog tias koj tab tom nrhiav cov ntaub ntawv hloov tshiab lossis yog tias koj xav tau hloov kho lawv rau lub hom phiaj tshwj xeeb, koj tuaj yeem rub tawm OpenScad cov peev txheej ntawm no

Kauj Ruam 4: Npaj Pawg Thawj Coj

Npaj cov laug cam

Xuab zeb G thiab E thiab kho 5 hli ntsia liaj qhov rooj rau E board (tuaj yeem ua tiav tom qab)

G yog xuab zeb kom tsis txhob thaiv cov ntawv

E yog xuab zeb kom tsis txhob thaiv cov xaim hluav taws xob

Kauj Ruam 5: Kho Qhov Siv Ntev

Kho qhov ntev ntawm txoj siv

Thaiv ib qho ntawm qhov kawg ntawm txoj siv nrog cov hlua nylon hlua (nco ntsoov muab lub taub hau ntawm dab tshos hauv lub dav hlau ntawm txoj siv)

Ua raws txoj hauv kev uas qhia hauv daim duab txuas rau txoj siv (muab 2 lub txiv ntoo tso rau ntawm lub axis loj kom ntseeg tau tias muaj qhov loj me)

Txuas qhov kawg thib ob nrog txoj hlua khi nylon

Kauj Ruam 6: Sib sau Solenoid Support

Sib sau ua ke cov kev txhawb nqa solenoid

Txuas txoj siv sib txuas ua ke ntawm txhua sab ntawm solenoid.

Txuas lub nplhaib tooj liab nrog nylon cable khi.

Txuas Solenoid nrog ntsia liaj qhov rooj. Ua siab tawv, yog tus ntsia liaj qhov rooj ntev dhau lawm nws tuaj yeem ua rau lub solenoid txav me ntsis. Yog li ntawd ntxiv qee lub nplhaib kom txo cov xov ntev

Yog tias txoj hlua siv twb tau ntev lawm koj tuaj yeem ntxiv nws ntawm cov theem no.

Kauj Ruam 7: Sib dhos Cov Qauv Tseem Ceeb

Sib dhos lub ntsiab ncej

Ntsia daim npav Arduino rau ntawm pawg thawj coj saib H.

Muab cov laug cam F, G thiab H hauv pawg B.

Pawg board C.

Xaub lub rooj tsavxwm F kom nws thaiv ob sab

Kauj Ruam 8: Nplooj Tsav Tsheb

Nplooj ntawv tsav tsheb

Zes daim ntawv tsav tsheb

Daim ntawv ceeb toom: Yog tias koj cov nplooj ntawv tsav tsheb tsis zoo ib yam, koj yuav tsum hloov kho lub rooj tsav xwm G hauv OpenScad kos duab (ntawm no)

Kauj Ruam 9: Damping Roj Hmab

Damping Roj Hmab

Ntxig cov roj hmab damping ntawm qhov xuas nrig ntaus. Txhawm rau kom ua kom nruj nws tuaj yeem muaj txiaj ntsig los lo rau txheej txheej txheej txheej ntawm rubbers ua ke.

Kauj ruam 10: Txuas

12v txuas

Ntxiv 12v txuas ntawm C board

Xaus qhov kawg ntawm kev mus ncig

Ntxiv qhov kawg-ntawm-kev hloov pauv mus rau C board. Txhawm rau tsim lub tshuab muaj kev nyab xeeb dua, nws tseem tuaj yeem ntxiv lwm qhov hloov mus rau pawg B.

Daim ntawv ceeb toom: hauv daim vis dis aus nws tau ntxiv rau pawg B vim nws yog lwm lub tshuab

Kauj ruam 11: Buid X Axis

Tsim X axis

Ntxiv D board ntawm sab xis.

Xaub 6mm hlau tuav pib nrog hauv qab ib qho.

Kauj Ruam 12: Nruab Txoj Siv

Nruab ib lub pluaj thiab ua rau nws protrude rau hauv lub notches ntawm txhua sab

Kauj Ruam 13: Hauv Tshuab

Txuas cov xov hlau raws li qhia hauv shema.

Tej zaum nws yuav muaj txiaj ntsig zoo los siv cov khoom txuas txuas rau solenoid thiab hloov qhov kawg ntawm kev mus ncig.

Kauj Ruam 14: Ntxiv Electronic

Txuas hluav taws xob

Plug lub cav thaiv rau Arduino board

Dhau Y lub cev xov hlau pov rau C thiab D cov laug cam qhov (X lub xov hlau yuav tsum nyob hauv)

Ntxiv solenoid tswj ib feem

Ntsia hlau xaim hluav taws xob (lub cev tiv thaiv kab mob thiab solenoid tswj ib feem ua ke)

Kauj Ruam 15: Ua Kom tiav Cov Rooj Sib Tham

Ua tiav thav duab sib dhos

Ntxig board I nyob tom qab (qhov uas muaj qhov)

Embed board A ntawm sab laug

Qhov rooj board E yam tsis yuam. Yog tias nws nyam, nco ntsoov khiav Y lub xov hlau nyob tom qab ntawm lub rooj tsavxwm E, kom ua tiav qhov no, tsuas yog rub cov xov hlau me ntsis los ntawm sab hauv ntawm cov khoom siv hluav taws xob.

Kauj Ruam 16: Mount X Stepper Motor

Mount X stepper motor ib sab kom suav nrog txoj siv

Txhawm rau zais cov xov hlau, lub txuas yuav tsum tau kos rau hauv pawg A

Txuas cov xov hlau los ntawm sab hauv thaum lub cav nyob hauv qhov chaw.

Kauj Ruam 17: Mount Y Stepper Motor

Ntxig lub nplhaib tooj liab rau ntawm pawg B

Ntxig 8 hli hlau pas nrig

Ntxiv 8mm rau 5mm txuas

Ntxiv Y stepper lub cev muaj zog

Tighten stepper thiab txuas cov ntsia hlau

Kauj ruam 18: Thauj khoom Arduino Sketch

Rub tawm

BraillePrinter.ino (cov ntaub ntawv hauv qab) lossis hloov kho tshiab ntawm no

Adafruit motor lib

Kauj Ruam 19: Khiav Lub Tshuab Luam Ntawv Braille

1. Txuas USB rau PC
2. Plug 12v fais fab mov
3. Ntxig rau daim ntawv A4 (160g yuav tsum zoo)
4. Qhib Arduino Serial Monitor thiab ntaus

{abcdefghij# klmnopqrst# uvwxyz

• {: initialisation
• #: pib kab tshiab (vim tias, ntawm cov cuab yeej txuas, xa rov qab siv tau xa tsis txhob suav nrog kab ntawv tshiab)
• a..z: char hloov mus rau 6 dot braille

Rq1: Cov syntax yuav tsum raug hloov kho yav tom ntej kom suav nrog kev teeb tsa

Rq2: Nov yog daim vis dis aus qub (TODO: hloov kho nws)
