Kuv xav tsis thoob kom pom tias cov cuab yeej siv cuab yeej kim npaum li cas. Lub tshuab ua paj ntaub braille tus nqi ntau dua 1000 $ USD thiab hluav taws xob mus los ntawm 3000 $ txog 5000 $. Kuv nyuaj txog kev ua ib tus phooj ywg tab sis kuv nrhiav tsis tau DIY version, yog li kuv txiav txim siab ua ib qho rau kuv tus kheej. Qhov no tsis yog, los ntawm ib txoj kev twg, yog cov khoom tiav. Los ntawm kev ua lub tshuab qhib qhov project, Kuv vam tias lwm tus yuav txhim kho kev tsim qauv. Nyob rau yav tom ntej, nrog kev pab los ntawm lwm tus tsim, OpenBraille yuav txo tus nqi ntawm cov tshuab luam ntawv no thiab nws yuav tso cai rau txhua tus uas tsis pom kev nyeem thiab sau ntawv. Yog li, yog tias koj paub ib tus neeg, yog tias koj yog tus tsim khoom, yog tias koj xav paub lossis yog koj xav pab, thov koj ua raws li cov lus qhia no thiab pab kuv tsim zej zog ib puag ncig OpenBraille.

Tus encoder zoo nkauj npaum li lub plawv ntawm tus embosser. Feem ntau ntawm cov tshuab ua lag luam emboss cov dots los ntawm cuam tshuam rau ntawm daim ntawv. Vim tias nws nyuaj rau tsim lub tshuab kom raug tawm ntawm 3D qhov chaw luam tawm, Kuv tau tsim cov kab ke sib txawv. Hloov chaw ntawm kev cuam tshuam thiab siv tag nrho lub zog hauv kev ntaus ib zaug, OpenBraille siv lub cev ntsuas lub cev thiab cov menyuam. Txoj kev no, cov embossing tau maj mam ua thiab cov khoom tuaj yeem luam tawm tau yooj yim.

Me ntsis ntoo ua haujlwm. Nws yuav tsum yog cov ntaub thaiv npog rau kev nyab xeeb tab sis nyob rau lub sijhawm nws tsuas yog thav duab. Nws yog lub hauv paus ntoo plywood muab tso ua ke los txhawb nqa cov khoom. Koj tuaj yeem saib cov phiaj xwm kom paub meej ntxiv. Nov yog qhov kuv tau tsim nws tab sis xav tias dawb los qhia qee yam zoo dua.

Cov pins tsuas yog cov khoom siv uas yuav tsum tau ua haujlwm. Rau txhua tus, koj yuav xav tau tus ntsia hlau thiab txiv ntoo hexagonal. Raws li cov cuab yeej, koj xav tau lub tshuab tig (dremmel) tus tuav tuav thiab xuas nrig ntaus.

Ua ntej tshaj plaws, lub taub hau ntawm tus ntsia hlau yuav tsum tau txiav. Lwm qhov kawg ntawm tus ntsia hlau yuav tsum tau muab zom ua ke, qhov no yog dab tsi yuav ua rau cov ntawv teev, yog li, ua kom zoo nkauj.

Tom qab ntawd, peb yuav tsum ua lub qhov rau txiv ntoo. Siv qhov xuas nrig los coj lub qhov. Tom qab ntawd, siv lub dremmel los ua kom tiav lub qhov.

Thaum kawg, nrog lub chaw nres tsheb soldering, ntxiv ib tee nyias ntawm cov txiv ntoo kom kho tus pin rau nws.

Cov ntawv luam tawm 3d yuav tsum tau muab ntxuav kom lawv haum zoo. Qhov rau cov pins me dua. Yog li ntawd, los ntawm kev siv dremmel nrog me ntsis ntawm qhov loj me ntawm tus pin lub qhov yuav zoo meej.

Lub servo tau txuas rau lub log los ntawm kev nias nws sab hauv. Tom qab ntawd, lub log_base yuav tsum tau sib xyaw ua ke nrog cov servo thiab lub log.

Tus tuav tus pin mus rau sab saum toj ntawm lub log nrog tus pin taw tes rau sab saum toj.

Ua ntej ua tiav ntu no, cov kabmob yuav tsum tau teeb tsa rau cov kabmob _support_inverse (raws li muaj npe nyob hauv cov ntawv). Cov kabmob tau tsim rau M4 screws.

Thaum kawg, lub hauv paus log tau teeb tsa ntawm cov kabmob txhawb nqa nrog ob M3 ntsia hlau. Kuv yuav tsum tau hlais me ntsis ntxiv ntawm lub ces kaum ntawm lub hauv paus log kom ruaj khov, thiab kuv siv tus thib peb M3 ntsia hlau.

Cov kabmob mus rau sab hauv cov menyuam, Kuv yuav tsum tau xuab zeb nws me ntsis thiab tom qab ntawd kuv nias cov kabmob sab hauv.

Cov menyuam mus rau hauv lub thawv ncej thiab npog tau tuav nrog M3 ntsia hlau.

Raws li daim duab qhia nws, lub thawv ncej mus rau hauv cov menyuam txhawb nqa thiab M3 ntsia hlau tso cai rau lub thawv ncej kom hloov kho.

Cov kab tawm kab yuav tsum tau teeb tsa hauv cov kabmob _support_normal (raws li muaj npe nyob hauv cov ntaub ntawv) nrog M4 screws.

Tam sim no cov menyuam tuaj yeem ntsia tau rau hauv kev txhawb nqa nrog ob M3 ntsia hlau.

Kauj Ruam 7: Ntsia Hlau

Muaj 4 txoj hlua. Ob txoj kab ncaj nraim rau cov kabmob thiab ob txoj hlua hlau txuas. Txhua tus pas nrig yuav tsum nyob hauv tib lub dav hlau. Txog qhov ntawd, muaj plaub lub spacers uas mus hauv qab cov hlau lead ntsaws. Vim tias kuv tsuas muaj ib tus ntoo loj me xwb kuv tau hloov me me kom raug kho qhov siab ntawm cov ntsia hlau. Round_9mm mus rau hauv tus pas nrig thiab Round_3mm mus rau hauv cov hlau lead ntsia hlau, koj kuj tseem tuaj yeem siv cov ntsia hlau nrog qhov ntev raug thiab tsis siv puag ncig.

Tag nrho cov pas nrig yuav tsum yog sib npaug. Rau cov kab ncaj nraim kom sib luag siv Calibration_spacer thiab Endstop_holder. Rau cov hlau lead ua kom sib luag rau cov kab ncaj qha siv cov menyuam sib dhos thiab cov cuab yeej sib sau ua ke. Muab cov rooj sib txoos nyob rau sab xis thiab ntswj cov ntsaws rau hauv lub rooj tsavxwm. Muab cov rooj sib txoos nyob rau sab laug deb thiab ntsaws cov nkhaus uas seem. Cov ntsia hlau lead yuav tsum tau tig dawb.

Cov steppers tau teeb tsa rau ntawm lub rooj tsavxwm nrog NEMA_support. Kev txhawb nqa muaj ob lub qhov rau M3 ntsia hlau. Ntsia qhov kev txhawb nqa rau hauv stepper thiab ntxig lub coupler rau hauv tus ncej. Kuv tau txais qhov tsis raug ntawm coupler yog li kuv yuav tsum tau muab cov raj nqaim rau lawv kom haum zoo. Tam sim no, txuas cov steppers rau cov hlau lead nrog cov couplers. Xyuas kom nws ncaj thiab ntsia hlau qhov kev txhawb nqa rau hauv lub rooj tsavxwm.

Kauj Ruam 9: Txhim Kho Z Axis thiab Lub Hwj Huam Fais Fab

Rau Z axis Kuv siv lub tshuab luam ntawv tsis tu ncua. Kuv pom lub tshuab luam ntawv qub thiab kuv muab nws sib nrug. Qhov kuv pom tsis tau siv cov steppers, nws siv dc motors nrog encoders … Yog li kuv yuav tsum hloov lub cav nrog tus stepper. Tsis tas li ntawd, plaub lub qhov yuav tsum tau muab hlais hauv lub tsheb thauj mus rau Z_supports. Z_supports tau teeb tsa rau hauv lub tsheb thauj khoom nrog M3 screws, tom qab ntawd, Z axis yuav tsum tau ntsia hlau rau hauv ntoo.

Kauj Ruam 10: Txuas Cov Khoom Siv Hluav Taws Xob

Cia peb sib sau lub hlwb ntawm lub tshuab luam ntawv. Kuv siv cov khoom siv hluav taws xob zoo tib yam npaj rau lub tshuab luam ntawv 3D. Ua ntej, peb yuav tsum tso tus tsav tsheb stepper rau hauv lub rooj tsav tsheb (cov pawg liab loj hauv cov duab). Muaj qhov chaw rau 5 tus neeg tsav tsheb, peb tsuas yog siv thawj 3, raws li daim ntawv lo hauv lub rooj tsav xwm tso cov tsav tsheb rau X, Y thiab Z (tsuas yog ib qho). Cov tsav tsheb (xim liab me me hauv cov duab) yuav tsum tau muab tso rau hauv txoj hauv kev, yog li saib cov duab ua ntej tso cov pins hauv lub taub hau. Tam sim no lub rooj tsav xwm tuaj yeem ntxiv rau arduino (pawg thawj coj xiav hauv cov duab).

Lub hwj chim yog txoj hauv kev loj dua qhov xav tau (Nws yog qhov kuv muaj). 12 V nrog 6 Amps yuav tsum muaj ntau tshaj li txaus.

Kauj Ruam 12: Khab nias

OpenBraille nws tus kheej yog tsim khoom ntawm LaCasaLab, lub tsev tsim tshuaj sim ua los ntawm kuv thiab kuv tus phooj ywgChristelle.

Kuv xav ua tsaug Sensorica thiab Eco2Fest, ob lub koom haum tau pab kuv nrhiav tus programmer.

Thiab tshwj xeeb ua tsaug rau David Pache uas tau teeb tsa tus neeg siv interface!
