Kuv kawm Game thiab Interaction technology ntawm Utrecht University of Arts. Muaj ib qhov haujlwm hu ua "Yog tias yog qhov ntawd" qhov uas koj tau thov kom tsim cov khoom sib tham. Koj yuav tsum siv Arduino, tsim cov ntsiab lus sib tham zoo thiab tsim qauv zoo thiab muaj txuj ci zoo saib ib puag ncig nws. Kuv muaj qee qhov kev xav ntawm tus kheej xav mus rau hauv txoj haujlwm no: Kuv xav kawm paub yuav ua li cas txhawm rau, Kuv xav kawm paub ua haujlwm hauv C/C ++ thiab kuv xav tsav 14 ntu ntu uas tau nyob ib puag ncig kuv qhov chaw tas mus li. Nws coj kuv ob peb lub lis piam los nrog lub tswv yim uas khi cov no ua ke tab sis thaum kawg nws tuaj rau kuv: Kuv yuav ua lub hauv siab uas koj xav tau qhib nrog tus lej, tab sis tsis muaj ib tus lej. Lub ntsuas ntsuas siab tau nyeem tas li thiab pom ntawm cov zaub, koj yuav tsum tau mus txog tus lej raug thiab lees paub nws peb zaug txhawm rau qhib lub hauv siab.

Kuv xav kom lub hauv siab kom muaj ib yam zoo li niaj hnub ua lag luam zoo yog li kuv cov khoom xaiv yog hlau thiab ntoo.

Thaum kawg kuv zoo siab heev nrog nws hloov li cas! Kuv tau sau cov theem hauv qab no yog li koj tuaj yeem rov tsim dua lossis txhim kho nws! Muaj kev lom zem!

Kauj Ruam 1: Sib Sau Cov Khoom

Kauj Ruam 2: Tsim Lub Hauv Paus - Cov Ncej Hlau

Lub hauv siab yog 30 cm lub voos xwmfab loj, ua los ntawm cov tub hlau thiab cov ntoo ntoo. Hauv lub nkas -las kuv pom cov raj zoo ntawm 20x20mm nrog 2mm tuab phab ntsa. Cov phab ntsa yuav tsum tau tuab txaus txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau M3 ntsia liaj qhov rooj. 2mm yog lub thickness zoo meej rau qhov no. Tau kawg koj tuaj yeem siv txhua yam hlau tub rau qhov no yog tias koj muaj lub tswv yim zoo dua.

Txoj kev zoo tshaj plaws los tsim tus ncej yog ua ob lub xwmfab ntawm 30x30cm thiab tom qab ntawd txuas ob lub xwmfab no siv 26cm (30 - 2*2) raj. Txhawm rau ua cov plaub fab, txiav cov kav hlau ntev hauv kab pheeb ces kaum ua yim daim. Qhov kawg ntawm daim yuav tsum tau txiav ntawm kaum ntawm 45 degrees tig mus rau ib leeg. Qhov ntev kawg ntawm daim yog 30cm. Thaum siv lub ntsia pom, nws yooj yim tig lub hau ntawm 45 degrees thiab tig lub raj tom qab txhua daim. Qhov no nkim tsawg cov khoom. Tom qab koj muaj yim daim kab pheeb ces kaum txiav nws yog lub sijhawm los txiav plaub qhov ncaj ntxiv. Cov ntawv no yog 26 cm ntev.

Tom qab ntawd thaum kawg txiav kaum daim ntawm ib ncig 6cm ntawm 20x4mm steel bar. Cov no yuav yog cov lus taw qhia rau cov ntoo ntoo.

Thaum tag nrho cov hlau tau npaj tiav, nws yog lub sijhawm rau weld. Qhov nyuaj tshaj plaws ntawm no yog txheej tawm lub raj uas koj tau txiav. Cia peb pib nrog cov xwm txheej saum toj thiab hauv qab. Nqa daim kab pheeb ces kaum thiab kab lawv tawm hauv ib lub xwmfab ntawm ib daim ntoo. Ib qho lus qhia ntawm no yog siv daim phiaj xwm txheej kwv yees li 30cm yog li koj tuaj yeem cia cov ces kaum poob ntawm cov ntug yog tias koj nteg lawv ntawm kaum ntawm 45 degree piv rau ntoo. Ceev lawv nrog qee qhov clamps thiab xyuas kom cov hlau kov hauv txhua lub ces kaum kom cov hluav taws xob tuaj yeem ntws los ntawm txhua daim mus rau tom ntej thaum txuas. Yog tias koj tsis tau welded ua ntej, tam sim no yog lub sijhawm los xyaum me ntsis vim tias yog koj cuam tshuam nws, koj tuaj yeem ua txhua yam kom deb li deb. Xijpeem, txuas cov khoom ua ke hauv cov ces kaum (Kuv tau xaiv ua nws sab hauv) thiab tam sim no koj tau ua tiav thawj ntu! Lub xwmfab thib ob yooj yim dua rau kab raws li koj tuaj yeem tso nws rau saum tus thawj. Weld cov no ua ke ib yam nkaus. Yog tias txhua yam mus zoo, tam sim no koj yuav tsum muaj ob lub xwmfab hlau zoo ib yam.

Txij ntawm no koj yuav xav muab cov ntsiab lus tso rau ntoo. Kuv siv ob daim rau txhua lub vaj huam sib luag ntawm qhov sib txawv ntawm lub voos xwmfab. Kuv xaiv tus qauv tshwj xeeb yog li tsis muaj ib daim yuav tsis tau txais txoj hauv kev ntawm lub hau thiab yog li kuv yuav tsis tau nce ob daim ntawm tib ntug. Koj tuaj yeem ua nws txhua txoj kev uas koj nyiam, tsuav yog ntug uas lub solenoid yuav raug kaw ntawm tsis muaj ib qho.

Txog tam sim no kuv kuj tau siv cov cuab yeej sib tsoo nrog txhuam hlau txuas los ntxuav cov hlau. Cov tuav tau qee qhov xeb me ntsis ntawm nws thiab kuv pom nws muab lawv saib zoo.

Txhawm rau ua kom tiav cov ncej hlau peb tsuas yog xav tau txuas ob lub xwmfab peb muaj tam sim no. Txoj hauv kev yooj yim tshaj plaws yog tso lawv ncaj rau ntawm ib qib thiab nteg ob ntawm 26cm raj ntawm lawv. Ib khub ntxiv ntawm tes yuav tuaj yeem pab tau heev thaum koj kaw lawv. Weld qhov no ua ke thiab rov ua dua rau lwm sab.

Yog tias txhua yam mus zoo, lub thav duab hlau yuav tsum ua tiav tam sim no!

Kauj Ruam 3: Tsim Lub Hauv Paus - Sab thiab Lub Hau

Txhawm rau ua kom lub hauv siab tiav, peb yuav tsum ntxiv ntoo ua vaj huam sib luag rau ob sab. Nco ntsoov tias cov khoom siv hluav taws xob yuav muab zais rau hauv lub hau, yog li koj yuav xav tau phaj me ntsis ntau dua li tsuas yog 6 daim ntawm 26x26cm. Ntawm DIY lub khw lawv muaj 122x61cm, uas yog qhov zoo tshaj. Kuv xaiv ntoo me ntsis me dua li kuv tau npaj tseg tab sis nws tau xaus zoo dua li cov ntoo tuab dua. Thaum cov raj hlau yog 2cm dav, tau muab cov ces kaum sib npaug thiab qhov dav yog 4mm dav, koj yuav nyob nrog 10mm rau lub vaj huam sib luag thaum tseem ua tib zoo saib. Cov phaj kuv pom tau yog 9 hli tuab yog li ntawd zoo meej.

Txiav cov phaj rau hauv rau lub vaj huam sib luag ntawm 26x26cm. Yog tias koj lub weld loj me ntsis koj yuav tsum txiav tawm cov ces kaum. Thaum koj muaj daim phiaj, muab lawv tso rau hauv tus thav duab. Nws yooj yim rau daim ntawv lo uas mus qhov twg. Nyob nruab nrab ntawm ntoo, kos qhov chaw uas ob lub qhov yuav nyob. Muab cov ntoo tso rau ntawm tus ncej ntawm nws qhov chaw ib puag ncig thiab laum lub qhov rau tus ntsia liaj qhov rooj. Kuv muaj M6 ntsia liaj qhov rooj nyob ib puag ncig tab sis ib qho ntsia hlau zoo. Cov ntsia hlau loj dua tuaj yeem ua rau nws zoo dua, tab sis txawm tias M3 tuaj yeem tuav nws ua ke kom zoo. Ua kom ntseeg tau tias cov ntsia liaj qhov rooj tsis ntev dhau, vim lawv yuav tawm mus rau hauv tus ncej. Nov yog qhov uas koj yuav tso koj cov khoom yog li thaum muaj cov ntsia liaj qhov rooj ntev tawm, nws yuav tsis yooj yim me ntsis. Yog tias koj siv qhov loj me ntawm cov khoom siv tib yam li kuv, 20mm ntsia liaj qhov rooj yuav tsum yog yam koj xav tau. Thaum lub qhov drilled koj tuaj yeem txhim kho cov phaj tab sis nco ntsoov tos nrog nrawm nrawm ua ntej lub hau ua tiav, koj yuav tsis xav xauv koj tus kheej!

Rau lub hau, peb pib nrog ib daim phaj uas peb txiav rau ob sab. Lub tswv yim yog ua lub hau rau hauv rooj plaub rau cov khoom siv hluav taws xob. Ntawm DIY lub khw kuv tseem pom ntoo 22x30mm, uas yuav ua rau muaj kev cuam tshuam zoo tshaj plaws. Nws muab peb centimeter qhov twg koj tuaj yeem zais koj cov hluav taws xob. Ua ntej muab cov no tso rau ntawm lub hau, peb yuav tsum ua lub qhov ntoo. Lawv yog txhua qhov puag ncig tshwj tsis yog ib qho rau cov zaub. Rau cov puag ncig, siv lub laum. Rau qhov siv me me, siv cov txheej txheem hauv cov duab saum toj no. Rau cov zaub koj tuaj yeem siv ib qho hluav taws xob jigsaw lossis tshuab milling yog tias koj xav kom meej dua. Thaum tag nrho cov qhov raug txiav thiab drilled, koj tuaj yeem lo cov ntoo ntawm ob sab ntawm lub vaj huam sib luag, hauv qhov chaw ncaj! Kuj tseem ceev faj tias koj lub solenoid tseem haum rau hauv qhov chaw uas seem lawm. Thaum nws yog txhua yam glued, ntsuas qhov tseeb thiab txiav ib lub vaj huam sib luag ntawm cov ntoo mus rau qhov ntev. Koj yuav twb xav ntsia hlau rau hauv qab ntawm cov ntoo ntoo kom koj tuaj yeem txiav cov ces kaum yaug nrog lub ces kaum ntawm lub vaj huam sib luag uas koj tau pib nrog.

Tam sim no peb yuav tsum ua cov nyees khawm rau lub ntsuas siab thiab khawm ua. Peb xav zais qhov khawm tiag tiag los ntawm tus neeg siv yog li peb yuav muab lawv tso rau hauv qab lub hau, sab hauv cov khoom siv hluav taws xob. Kuv tsuas yog txiav ob peb daim ntoo me me los ntawm cov plywood uas seem los ua cov spacers. Siv lub laub-khawm mus rau PCB thiab ntsia hlau rau ntawm cov ntoo uas tau lo rau sab hauv qab ntawm lub hau, ua kom lub pob tawm los raws nraim hauv nruab nrab ntawm lub qhov. Lub siab ntsuas sib txawv me ntsis. Txog qhov no, siv ob daim spacer txuas rau lub hau ib yam nkaus tab sis siv daim thib peb los ua tus choj hla lub qhov. Muab cov kua nplaum tso rau hauv nruab nrab ntawm lub qhov.

Txhawm rau tswj cov nyees khawm hla lub hau, nws yuav zoo tagnrho rau 3d-luam qee yam. Hmoov tsis kuv tsis muaj sijhawm rau qhov no yog li kuv tau tsim kho. Koj tuaj yeem ua txhua yam koj xav tau, tab sis cov lus qhia ntawm no yog qhov koj xav tau qee yam los thaiv lub pob kom tsis txhob poob ntawm ob sab. Kuv siv cov ntsia hlau luv nrog cov txiv ntoo txiav hauv ib nrab ntawm ib qho kawg thiab kuv tau npog nws nrog qee yam uas kuv pom nyob ib puag ncig.

Qhov ntxiv mus rau mount yog solenoid. Txhua qhov solenoid yog qhov sib txawv me ntsis tab sis txoj hauv kev yooj yim tshaj plaws rau solenoids feem ntau yog txheej ntoo ntawm cov cib thiab lub hau kom txog rau thaum nws ntog raws lub thav duab, tab sis tseem nyob deb txaus kom tsis kov ntoo thaum nws txuas ntxiv. Rau kuv qhov no yog 6mm. Kuv yuav tsum tau zom qee cov hlau tom qab dua vim tias thaum kawg nws tseem tsis nyob deb txaus. Kuv yuav tsum tau muaj txog 7 lossis 8 hli.

Lub hau tam sim no feem ntau ua tiav thiab tsuas yog cov khoom siv hluav taws xob xav tau ntxiv. Qhov no yog lub sijhawm zoo los xub txuas lub hau rau lub thav duab. Sim kom tau qee lub pob khawm me me ntawm lub khw muag khoom hauv zos, cov no yuav tsum tsis txhob loj dua cov hlau hlau (~ 18mm)! Nyob ntawm qhov loj thiab qhov zoo ntawm cov khawm no, koj tuaj yeem siv ob lossis peb qho. Kos lawv txoj haujlwm ntawm tus ncej thiab ntawm lub hau. Tam sim no tau txais ob txhais tes ntxiv uas yuav tuav lub hau nyob hauv qhov chaw thaum koj kos cim qhov twg los laum qhov. Lub qhov nyob hauv cov raj hlau yuav tsum tau xaws kom koj thiaj tuaj yeem ntsia tau rau hauv cov ntsia liaj qhov rooj yam tsis tas yuav txhawj xeeb txog yuav ua li cas thiaj nrawm. Thaum lub pob khawm tau txuas rau tus ncej, rov qab cov tes ntxiv thiab ntsia hlau lub hau ntawm lub pob khawm siv qee tus ntsia hlau me. Vim tias koj yuav tsum tau ua haujlwm ntawm lub hau tom qab dua koj tuaj yeem tos nrog cov kauj ruam no ib yam kom txog thaum txhua yam ua tiav.

Tam sim no, peb tau npaj ua haujlwm ntawm cov khoom siv hluav taws xob!

Kauj Ruam 4: Cov Khoom Siv Hluav Taws Xob

Lub Circuit Court muaj tsib txoj kev sib cais. Feem ntau ntawm cov no yog qhov yooj yim zoo nkauj: coj yooj yim nrog tus tiv thaiv lossis khawm thawb txuas nrog tus pin Arduino. Ob qhov kev sib tw nyuaj dua yog qhov uas ua rau lub vijtsam thiab xauv solenoid.

Cov zaub muaj 15 tus pin sib txawv uas yuav tsum tau tsav. Ib qho yooj yim Arduino tuaj yeem tsav ntawm 19 tus pin. Kuv xav tau 5 tus pin ntxiv rau qhov tsim ntawm qhov tsim yog li kuv tau ua haujlwm luv. Kuv pom qhov kev daws teeb meem siv I2C uas tau tsav I/O nthuav dav, MCP23017. Ua ke nrog Adafruit lub tsev qiv ntawv rau lub cuab yeej no, nws yooj yim heev rau siv. Ib feem ntawm qhov kev sib txuas uas txuas nrog tus pin GPA0 tau siv los hloov ntawm ob qho kev sib txuas ntawm HDSP-A22C zaub. Thaum nws siab, nws tsav tus yam ntxwv 1 thiab thaum nws qis nws ua rau tus cwj pwm 2. Qhov tsis zoo rau kev siv lub tshuab nthuav dav no yog nws sau rau cov pins tso tawm sai li sai tau byte tau sau. Qhov no ua rau ghosting. Tu siab kuv tsis muaj peev xwm daws qhov no nrog kho vajtse yog li kuv siv software los hla qhov teeb meem.

Txij li cov solenoid kuv siv tau tsav los ntawm 12V (rau qhov uas koj tuaj yeem siv ib qho 12V fais fab mov, ntsaws nws hauv Arduino thiab txuas cov xaim rau nws), Kuv xav tau lub tshuab hluav taws xob txuas (Darlington) los tsav nws nrog tus pin Arduino. Tsis tas li tsis txhob hnov qab lub diode kom dampen ncov ncov tam sim no tsim los ntawm cov tshuab hluav taws xob hauv solenoid!

Thaum siv cov khoom siv hluav taws xob, nco ntsoov qhov twg koj yuav tso lawv. Kuv khaws ciam me me nyob ib puag ncig tag nrho kuv cov laug cam yog li kuv tuaj yeem ntsia lawv ntawm qee qhov spacer pieces (cov khoom seem ntawm cov vaj huam sib luag sab) glued rau lub hau. Rau cov LEDs koj tuaj yeem txuas cov xaim nrog cov tiv thaiv ncaj qha mus rau LED thiab siv cov raj cua sov kom npog nws thiab kom ntseeg tau tias nws tsis tawg. Siv cov kua nplaum kub los khaws tag nrho cov xov hlau txuas ncaj qha mus rau lub rooj tsavxwm kom tsis txhob tawg.

Tom qab txhua yam tau muag lawm, nws yog lub sijhawm los txuas txhua yam! Kuv tau txais qee tus poj niam lub taub hau los nthuav 5V thiab GND txoj kab, yog li kuv tsis tas yuav muab txhua yam sib dhos ua ke thiab yog li kuv tuaj yeem yooj yim txuas lossis hloov qee yam yog tias nws tawg. Yog tias koj siv ntoo zoo ib yam rau ob sab ntawm lub hau zoo li kuv, koj yuav pom tias tsis muaj chav ntxiv los ntsaws dab tsi rau Arduino. Qhov kev daws teeb meem yooj yim tshaj plaws no tsuas yog khoov tus pin ntawm lub kaum sab xis 90-degree thiab ntsaws lawv rau hauv txoj kev ntawd.

Qhov kawg yog qhov yooj yim tshaj plaws thiab yog txhawm rau upload cov cai.

Kauj ruam 5: Txoj Cai

Txhua qhov chaws tau siv PlatformIO. Yog tias koj tsis paub txog qhov no, koj tuaj yeem yooj yim luam thiab muab tso rau hauv daim duab Arduino. Yog tias koj yog koj tuaj yeem rub tawm qhov program thiab rub nws mus rau koj Arduino. Cov lej tuaj yeem pom ntawm kuv Github. Ua tibzoo saib ib puag ncig hauv ntu program teeb tsa thiab hloov qhov txiaj ntsig raws li koj pom zoo (tshwj xeeb tshaj yog cov pins thiab ua ke). Kev sib xyaw ua ke yog 43 - 50 - 99.

Kauj Ruam 6: Tiav Touches

Tom qab txhua yam ua tiav thiab teeb tsa thiab pib ua haujlwm, peb tau npaj ntxiv qhov kawg ntawm qhov nthuav dav uas yuav tso cai rau txhua yam ua haujlwm.

Txhawm rau tiv thaiv lub hau kom tsis txhob poob los ntawm tus ncej, koj tuaj yeem txhim kho ob daim phiaj thaiv uas tau muab tso rau sab ntawm lub hau. Kuv siv 25x4mm steel bar kuv pom, txiav nws ua tej daim ncig ntawm 8cm, Kuv tau xaum qhov hauv lawv thiab ntsia lawv rau ntawm lub hau.

Lwm qhov kuv ntxiv rau lub hau yog tus tuav - muaj txiaj ntsig zoo yog tias koj puas xav qhib nws. Kuv yuav tsum tau laub tob rau hauv ob sab ntawm lub hau kom rub nws tab sis nws tig tawm zoo saib.

Lwm qhov kov tseem ceeb yog ntxiv cov chord me me los tiv thaiv lub hau kom tsis txhob poob rov qab thiab ua rau lub pob khawm puas. Kuv qhov kev daws teeb meem yog siv cov ntsia hlau txuas rau ntawm lub hau thiab sab hauv ntawm lub hauv siab uas kuv tuaj yeem txuas tus chord.

Txhawm rau kom tau txais lub zog sab hauv lub hau, laum ib lub qhov me me ntawm ib qho ntawm cov ntug thiab pom nws tawm sab saud. Muab cov ntsia hlau tso rau lwm qhov ntug thiab khi-qhwv lub chord rau cov ntsia hlau kom tiv thaiv ib tus neeg los ntawm kev ua yuam kev rub tawm lub zog chord thiab xauv koj tawm hauv siab mus ib txhis.

Thaum kawg, koj yuav tau pom tias koj tseem tsis tuaj yeem kaw lub hau. Qhov no yog vim muaj cov txiv ntoo hauv txoj kev. Tsuas yog txiav me ntsis ntoo tam sim no los ua chaw rau cov txiv ntoo no.

Thiab qhov ntawd yog nws! Qhov no yog li cas koj tuaj yeem rov tsim dua lub hauv siab cov khoom lag luam digital koj tus kheej! Thiab tsis txhob hnov qab hnav cov iav tiv thaiv kom zoo thaum siv cov cuab yeej muaj zog txaus ntshai!
