Tsis tas li kuv tau ua 7 ko taw hlua (3 xaim rau WS2811) los ntawm Pixel Controller mus rau WS2811 strands. Hauv kuv qhov xwm txheej 3 ntawm lawv txuas rau 150 ct LED strand, 150 ct LED strand, thiab 50 ct LED strand

Kauj Ruam 4: Npaj Txoj Haujlwm hauv Xlights

Xlights yog software siv los ntawm ib feem loj ntawm DIY Christmas Lights zej zog los ua ke ua ntu zus/ua yeeb yam. Hauv Xlights muaj tus qauv tshwj xeeb uas tus neeg siv muab daim ntawv nthuav qhia nrog tus lej rau txhua txoj haujlwm pixel. Google "xlights tus qauv kev cai" rau cov peev txheej ntau ntawm qhov no.

Nrog 400 pixels txawm hais tias, nws tuaj yeem nyuaj rau tsim cov qauv kev cai. Qhov kuv tau ua yog tsim cov xlights ntu uas kuv ua si ·

• Thawj 25 lub teeb liab ·
• Tom ntej 25 teeb ntsuab ·
• Tom ntej 25 teeb xiav ·
• Tom ntej no 25 teeb liab ·
• Tom ntej 25 teeb liab ·
• Lwm yam

Tom qab ntawd nrog kuv lub xov tooj ntawm tes tsau rau ntawm lub rooj Kuv nqa lub xov tooj ntawm tes video ntawm cov ntu ua si, txhua lub pixel ci rau kwv yees. 1-2 vib nas this. Kuv siv Sony Vegas txhawm rau muab daim phiaj tso rau ntawm daim vis dis aus yog li kuv tuaj yeem tau txais qhov chaw yooj yim rau txhua lub pixel. Nrog 400 lub teeb txawm li cas los yuav muaj kev sib tshooj nrog ntau LEDs nyob hauv tib daim phiaj sib koom tes, uas tsis yog qee yam Xlights tuaj yeem daws tau. Hauv kuv qhov xwm txheej Kuv tau tsim ib txoj haujlwm hauv C txhawm rau nyeem hauv daim ntawv teev npe thiab txiav txim siab rau lawv, txawm li cas los xij ib tus tuaj yeem ua tiav qhov no los ntawm txhais tes hauv Excel lossis Google Docs.

Kauj Ruam 5: Pob (Mini Projector Screens)

Tshaj li qhov projecting video los ntawm lub projector ntawm tsob ntoo nws tus kheej, Kuv kuj xav tau lub vijtsam saib ib txwm uas tuaj yeem pom cov vis dis aus zoo ntawm nws. Li no 3 pob khoom plig hauv qab tsob ntoo ua haujlwm zoo ntawm kev ntes feem ntau ntawm cov vis dis aus dav. Ib qho lus ceeb toom yog tias kuv muaj teeb meem nrhiav cov ntawv qhwv uas yog Matte lossis Ca. Feem ntau ntawm yam uas muaj yog ci. Yog li tom qab qhwv txhua qhov tam sim no kuv tau txau lawv hauv 5-6 lub tsho ntawm cov xim dawb-dawb

Kauj Ruam 6: Teeb Projector

Hauv kuv qhov xwm txheej kuv chav teeb muaj hmoo muaj lub teeb pom kev zoo ntawm qhov chaw zoo tshaj thiab nyob deb ntawm tsob ntoo kom tso cai rau kuv kom teeb lub projector ib sab thiab npog los ntawm hauv qab ntawm pob khoom mus rau saum tsob ntoo. Teeb tsa lub projector hauv kev teeb tsa lub npe lossis kab rov tav yuav xav tau thawb lub projector dhau mus. Kev saib xyuas thiab ntsuas kuj tseem yuav tsum tau nkag mus rau lub projector ntawm lub kaum sab xis kom raug (tsis zoo ib yam li koj tuaj yeem qhia los ntawm cov duab) kom npog qhov xwm txheej.

HDMI los ntawm Raspberry Pi, uas Falcon Pi Player siv rau cov vis dis aus, tau hla mus rau lub projector.

Los ntawm kev tshawb fawb ntawm ntau lub rooj sab laj AV, kev teeb tsa lub projectors hauv qhov tsis yog kab rov tav teeb tsa yuav cuam tshuam rau cov cua sov uas tsis zoo ib yam li cov projectors tau ua kom zoo dua rau cov cua sov sib kis hauv kab rov tav. Txawm li cas los xij, txij li thaum kuv ua yeeb yaj kiab video ua yeeb yam uas tsuas muaj lub projector siv rau 15 feeb, Kuv tsis txhawj xeeb dhau. Ntau qhov kev txhawj xeeb ntawm AV rooj sab laj tau nrog cov neeg siv uas xav kom muaj lub projector nyob ntev (> 2 teev).

Kuv tuav kuv lub xov tooj ntawm tes kom ntxaws nyob ib sab ntawm kuv lub lens projector thiab tsom nws ntawm tib lub kaum ntse ntse zoo li lub projector yuav tsim video. Tom qab ntawd kuv siv tus kws kho duab los tsim lub npog ntsej muag ntawm thaj chaw uas kuv tuaj yeem siv nrog kho video SW, Sony Vegas. Qhov no tau hais ncaj ncaj, txawm hais tias nco qab hauv Video Editor uas nce = Sab xis ntawm tsob ntoo, Txoj cai = nqis rau ntawm tsob ntoo tau ua rau lub sijhawm tsis zoo.

Kauj Ruam 7: Xaus

Kev tsim kom txog qib kev ua yeeb yam no tau dhau qhov kev hloov pauv ntawm 4 xyoos ntawm Christmas Tsob Ntoo qhia, tab sis kuv xav siv tib qib ntawm WOW qhov uas lwm tus pom ntawm lawv sab nraum Christmas teeb pom rau tsob ntoo sab hauv.

Yog tias koj nyiam qhov kev qhia no, pov npav hauv qhov kev sib tw kuv tau nkag mus rau hauv. Ua tsaug!
