Koj ua dab tsi thaum koj tsis tuaj yeem txiav txim siab yam koj xav ua rau Xus? Ua txhua yam. Lub npog ntsej muag yog suav nrog daim npog 3D luam tawm dawb, lub paj yeeb raspberry, lub me me projector thiab lub roj teeb. Nws muaj peev xwm kwv yees txhua yam thiab txhua yam rau ntawm koj lub ntsej muag. Kuv yuav qhia qee qhov cuam tshuam txias hauv kuv daim vis dis aus, tab sis kuv txhawb koj kom sim thiab tawm los nrog qee qhov ntawm koj tus kheej.

Kauj ruam 1: Saib Video

Kauj Ruam 2: Pib Nrog 3D Luam Ntawv

Cov ntawv luam no yuav siv sijhawm ntev. Tau txais "taub hau" pib los ntawm kev luam tawm lawv thaum koj ua lwm yam.

Cov ntaub ntawv nyob ntawm Thingiverse ntawm no:

Koj tuaj yeem luam tawm 4 cov ntaub ntawv hauv ib zaug, tom qab ntawd luam daim npog qhov ncauj ntawm nws tus kheej. Luam daim npog ntsej muag dawb, uas yuav cawm koj ntawm kev pleev xim rau nws. Koj yuav tsum pleev xim rau lwm qhov xim dub vim yog 1/2 ntoo square dowel.

Yog tias koj zoo nkauj tiag tiag koj tuaj yeem xuab zeb pem hauv ntej ntawm daim npog ntsej muag thiab ntxiv cov xim dawb matte. Kuv tsis tau ua qhov no tab sis nws yuav du tawm cov kab ntawv luam.

Kauj Ruam 3: Txhim Kho Cov Ntsia Hlau Thaum Tshav Kub Kub hauv 3D Luam Ntawv

Muaj ob lub M3 threaded inserts hauv lub puab tsaig, thiab 6 hauv qhov projector mount, saib cov duab.

Cov nyob hauv lub puab tsaig yuav mus rau sab uas tig koj lub puab tsaig, qhov no yuav ua rau lawv muaj zog ntxiv. Xyuas kom lawv ncaj heev li cov ntsia hlau yuav nkag los ntawm lwm sab los ntawm cov ntawv luam tawm thiab mus rau hauv cov xov ntsaws. Qhov no ua kom lawv tsis tuaj yeem rub tawm los ntawm ib feem.

Kauj Ruam 4: Txiav Ntoo Ntoo

Cov ntoo ntoo yuav tsum tau txiav rau 420mm ish. Tsis yog qhov tseem ceeb tshaj plaws.

Kauj Ruam 5: Sib sau ua ke thiab pleev xim

Ntsuas haum txhua yam ua ke thiab xyuas kom txhua yam yuav ua haujlwm. Pem hauv ntej ntawm lub ntsej muag thiab pem hauv ntej ntawm pi mount yog ~ 360mm sib nrug. Ntsia lawv rau hauv lub qhov hauv qhov chaw ntsia hlau hauv daim ntawv. Tom qab ntawd tshem daim npog ntsej muag thiab pleev xim rau lwm yam ua ke nrog cov xim dub matte. Xim cov ntsia hlau thiab txhua yam. Koj xav kom nws ua kom pom ntau li ntau tau.

Kauj Ruam 6: Teeb Lub Taub Hau Mount

Lub kaus mom hlau txuas txuas yog qhov kev daws teeb meem zoo los tuav daim npog no. Ntau npaum li ntawd kuv yuav tau siv ntau ntxiv rau cov haujlwm yav tom ntej.

3D luam tawm rau lub npog ntsej muag twb muaj qhov rau qhov nws xav tau nce, tab sis lub taub hau tsis ua. Thaum koj tuav lub npog ntsej muag nyob hauv qhov chaw raug ntawm koj lub ntsej muag, kom muaj ib tus neeg cim qhov chaw ntawm lub taub hau. Koj yuav tsum tau laum qhov ntawm no kom tso cai rau nws nce. Kuv kuj txiav tawm lub tab me me los tuav cov ntaub mos muag (uas zaum ntawm koj lub hauv pliaj) kom muab kev tshem tawm ntau dua rau daim npog ntsej muag. Kuv muaj peev xwm siv daim kab xev ob tog los qhwv nws rov qab.

Thaum koj tau npog lub npog ntsej muag tag nrho, koj yuav xav tau muab qee cov npuas dej tso rau ntawm lub npog ntsej muag qis dua. Kuv nyob ntawm kuv lub puab tsaig kom txhawb nqa, thiab nws tuaj yeem mob tom qab ib ntus.

Kauj Ruam 7: Solder PCB, Sib Sau Ua Ke

Tsis muaj ntau yam ua rau ntawm lub rooj tsav xwm. Ob 46 Pin headers rau lub projector, 40 tus pin header rau pi, tus kiv cua header, 2N7002 mosfet, thiab 10K resistor.

Raws li kuv tau hais hauv daim vis dis aus. Kuv tsis tau muab cov khoom sib txuas los tshuaj xyuas kab 5V rau pi. Kuv nyuam qhuav dhia los ntawm Projector 5V mus rau pi 5V kab. Saib duab.

Thaum txhua yam tau muab sib dhos ua ke koj tsuas tuaj yeem ntsaws rau hauv txhua lub taub hau ua ke. * Koj yuav tsum khoov tus pin 43 ntawm lub projector, nws yog yuam kev hauv av ntawm pawg thawj coj saib* Yog tsis yog nws qhia lub projector kom nyob twj ywm. Yuav tsis ua dab tsi yog tias koj ua yuam kev tsis. Tsuas yog yuav tsis muaj qhov tso tawm los ntawm lub projector.

Lub pcb thiab pi yuav nce mus rau lub projector, thiab yuav muab nruab nrab ntawm lawv nrog cov ntsia hlau los ntawm sab nraud ntawm lub tsev mus rau hauv lub projector standoffs.

Yog tias siv lub kiv cua, koj yuav tsum tau ntsaws lub kaum sab xis txuas ua ntej koj ntsaws lub kiv cua. Kuv tsis ntseeg tias tus kiv cua xav tau tiag tiag. Tus kiv cua kuj tseem yog qhov sib txhuam haum, Kuv siv cov hlau los ntawm tus kiv cua kom muab lub zog me ntsis ntxiv, thiab siv cov hlau tsawg dua.

Kauj ruam 8: Teeb tsa Pi

Kuv pom tag nrho cov ntaub ntawv xav tau kom tau lub projector ua haujlwm ntawm pi ntawm lub vev xaib no. https://frederickvandenbosch.be/?p=2948 - Nws piav qhia yam yuav tsum tau ua rau pi cov ntaub ntawv teeb tsa, thiab muab cov ntaub ntawv ntau ntxiv ntawm lub projector feem ntau, tsim nyog nyeem yog tias koj yuav ua txoj haujlwm no.

Raws li tau hais hauv daim vis dis aus, koj yuav tsum tau tig qhov kev daws teeb meem rau qhov dav thiab qhov siab vim tias koj yuav siv pi hauv hom duab. Koj tseem yuav xav tau ntxiv "display_rotate = 1" kom tau cov zaub kom tig ib sab.

Saib duab.

Txhawm rau ua yeeb yaj kiab koj yuav tsum muaj OMXPlayer teeb tsa.

Rau lub suab koj tuaj yeem siv tus hais lus bluetooth. Kuv tsis tau muaj txiaj ntsig zoo nrog kuv, tab sis kuv ntseeg tias nws yog tus hais lus.

Kauj Ruam 9: Tsim Yeeb Yaj Kiab rau Pi

Qhov no nyuaj me ntsis los piav ntawm no, yog li nco ntsoov xa mus rau cov vis dis aus.

Koj yuav tsum tau ua cov yeeb yaj kiab uas haum rau sab hauv ntawm qhov chaw npog ntsej muag kom ua si ntawm daim npog ntsej muag. Kuv tau suav nrog cov ntaub ntawv kuv siv los ua kuv tus kheej cov duab. Koj tuaj yeem siv lawv hauv koj li software tsim software los kho lub ntsej muag, khoom, xim, koj lub npe.

Yog tias koj siv cov duab ntawm lub ntsej muag, koj yuav tsum hloov qhov kev xav ntawm lawv kom rov qab, tib txoj kev uas lub projector tau ua tsis raug nrog lub npog ntsej muag.

Kauj Ruam 10: Teem Lub Projector

Tam sim no koj tau ua ob peb cov vis dis aus siv ib qho ntawm lawv los kho lub ntsej muag. Kuv tau suav nrog cov vis dis aus uas ua kom yooj yim dua. Muaj peb qhov ntsia hlau uas tau siv rau kev teeb tsa lub projector mus rau lub pas nrig. Qhov no tso cai rau koj tig lub projector hauv cov lus qhia sib txawv kom ua kom nws sib koom. Koj yuav tsum tau plam hauv shim lossis ob qho kom nws mus txog qhov siab kom zoo ib yam.

Cov lus qhia Pro, ncua kev ua yeeb yaj kiab nrog "p" qhov tseem ceeb nrog OMXPlayer.

Kauj Ruam 11: Ua Si Yooj Yim Yooj Yim ntawm Pi

Kuv yuav xav tias koj muaj qee qhov kev paub hauv kev tswj hwm lub taub hau pi. Feem ntau los khiav cov vis dis aus ntawm tus pi koj yuav xav tau SSH hauv, thiab khiav cov lus txib rau OMX player. Kuv pom qhov kev daws teeb meem uas ua haujlwm zoo dua rau thaum koj hnav ib yam dab tsi uas koj tuaj yeem pom tsis tau.

Muaj ib qho app hu ua "RaspController" rau hauv. Qhov app pub dawb no tso cai rau koj nkag mus rau cov lus txib uas koj ib txwm nkag mus rau hauv lub davhlau ya nyob twg, tab sis muab lawv tso rau hauv cov nyees khawm yooj yim. Koj tuaj yeem tshawb xyuas lub app vim nws yog qhov nkag siab heev.

Cov lus txib uas koj yuav tsum paub los ua yeeb yaj kiab yog:

omxplayer path/to/video.mp4-pom-hom ncab

yog tias koj xav khiav cov vis dis aus nrog tus hais lus bluetooth ces:

omxplayer path/to/video.mp4 -o alsa --aspect -mode stretch

Qhov "--cov duab-hom ncab" yog qhov tseem ceeb vim nws yuav ua kom cov vis dis aus zoo haum rau pi projector.

Yog li piv txwv, yog tias kuv xav ua si kuv cov vis dis aus uas nyob hauv ~/Videos/intro.mp4 cov lus txib yuav yog:

omxplayer ~/Yeeb yaj duab/intro.mp4 --aspect-mode stretch

Kuv muaj tag nrho cov lus txib sib txawv rau cov yeeb yaj kiab sib txawv yog li kuv tuaj yeem ua ntu ntu thaum kuv taug kev ncig Halloween party uas kuv nyob.
