Txoj haujlwm no mus dhau qhov peb ua DIY 3D LED Lub Vev Xaib los ntawm ws2812b LEDs. Lub voos xwmfab yog 8x8x8 ntawm LEDs, yog li 512 tag nrho, thiab cov khaubncaws sab nraud povtseg yog ua los ntawm cov ntawv acrylic uas peb tau txais los ntawm lub tsev muag khoom. Cov yeeb yaj kiab tau siv los ntawm raspberry pi thiab 5V lub zog siv. Lub voos xwmfab yog ib qho zoo heev los qhia tawm rau phooj ywg thiab tuaj yeem ua lub teeb. Peb qhov loj me me rau teeb (2ft x 2ft x 2ft), tab sis koj tuaj yeem ntsuas qhov no kom haum rau koj cov kev xav tau.

Khoom siv

  1. ws2812b LED Qij -
  2. 5V Cov Khoom Siv Hluav Taws Xob -
  3. Raspberry pi 3b Kuv siv (tuaj yeem siv ib qho) -
  4. SN74HCT125 Cov Hluav Taws Xob Hluav Taws Xob - dhia hluav taws xob los ntawm raspberry pi teeb liab kom muaj qhov hluav taws xob tsim nyog rau coj sawb (Kuv ib txwm tau txais kuv cov ntu ntu los ntawm Digikey)

Peb tab tom ua 8x8x8 lub voos xwmfab nrog txoj hlua ws2812b coj. Cov leds tau sib cais los ntawm 3 ntiv tes, yog li lub teeb yuav yog li 21inches los ntawm 21 ntiv tes ntev. Peb tau xaiv los ua cov ntawv acrylic tsawg dua 2ft x 2ft los daws qhov no. Qhov ntawd txhais tau tias peb tuaj yeem ua 8 txheej los ntawm ib daim ntawv ntawm 4ft x 8ft acrylic.

Peb pib los ntawm kev tawg 4ft x 8ft thooj rau hauv 2 daim ntawm qhov sib npaug sib npaug (~ 2ft x 8ft) nrog lub rooj pom. Tom qab ntawd, peb siv ib daim los ua tus qauv los kos kab uas siv tus cim laum qhuav kom sib npaug sib npaug ntawm daim. Tom qab ntawd peb siv tus ntug ncaj thiab lub ntsej muag pom los ua 8 txheej plaub fab.

Tom qab txhua ntawm 8 txheej tau txiav rau qhov loj me, peb kos tawm qhov kev ntsuas rau qhov LEDs yuav tsum nyob qhov twg. Peb tau siv tus cim laum qhuav thiab lub ntug ncaj rau nruab nrab ntawm lub xwmfab coj. Txij li thaum peb muaj 8x8x8 coj lub voos xwmfab, yuav muaj 64 LEDs ntawm txhua txheej ua raws kab sib chaws uas muaj li 3 ntiv ntawm nruab nrab LEDs uas nyob ib sab.

Thaum lub qhov raug cim tawm, laum tawm 1/2 nti qhov nrog cov ntu ntu me ntsis. Qhov no yuav ua kom ntseeg tau tias cov acrylic tsis tawg. Peb tau muaj teeb meem siv cov ntu me ntsis ib txwm ntawm cov khoom no thiab yuav tsum tau ua ntu ntu me ntsis kom ua tiav qhov txiav. Txij li thaum daim tau raug sib dhos ua ke, peb tsuas yog yuav tsum tau laum tawm 64 qhov. Peb kuj ua ib txheej tawm ntawm plywood uas yuav yog hauv qab ntawm lub voos xwmfab. Tom qab lub qhov raug laum tawm, peb pub cov qij LED hla txhua qhov. Peb siv tus qauv serpentine los taw qhia cov coj hauv txhua kab.

Tom qab txheej tau ua nrog cov leds hauv txhua qhov, mus tom ntej thiab muab cov txheej txheej siv 3 nti daim ntawm acrylic ua qhov sib txawv. Peb kub glued tag nrho 8 txheej ua ke nrog 5 spacers ib txheej. Tom qab ntawd peb rov qab los nrog ntev dua 2 taw ntawm cov acrylic thiab txhawb ob sab ntawm lub voos xwmfab. Nov yog thawj kauj ruam peb tau pom lub voos xwmfab los ua ke, thiab nws zoo heev.

Tam sim no tias cov txheej tau ruaj ntseg tag nrho, peb yuav tsum tau muab cov kab sib txuas sib txuas ntawm cov khaubncaws sab nraud povtseg. Txij li thaum peb muaj tus lej ntawm cov leds (8), hauv txhua txheej peb tau xaus cov kab txaij ntawm LEDs ntawm tib sab ib sab thaum pib ntawm kab txaij. Tom qab ntawd peb txuas txhua txheej rau txheej saum toj no, uas nyob rau hauv lem ua ntsug serpentine qauv txuas txheej. Tom qab cov txheej txheem tau txuas nrog peb ua ib qho yooj yim Circuit Court raws li pom hauv daim duab txuas rau xa cov ntaub ntawv los ntawm raspberry pi mus rau ws2812b leds. Txij li raspberry pi tso tawm ntawm 3.3V teeb liab thiab peb xav tau 5V teeb liab kom raug xa cov ntaub ntawv mus rau ws2812b leds, peb siv SN74HCT125 kev sib txuas ua ke kom nce qhov hluav taws xob.

Thaum cov phiaj xwm tau teeb tsa mus tom ntej thiab rub tawm cov cai los ntawm kuv qhov chaw cia khoom github. Peb muaj cov pawg ua yeeb yaj kiab thiab ntau ntxiv tuaj, xav tias dawb los saib. Kuv siv BiblioPixel lub tsev qiv ntawv los kos duab ua duab rau ntawm lub vijtsam thiab BiblioPixelAnimations lub tsev qiv ntawv los theej qee cov lej ua yeeb yaj kiab. Txij li thaum BiblioPixel tsis ua haujlwm raug ib lub voos xwmfab ntsug snaking, kuv yuav tsum hloov kho txoj cai me ntsis los daws qhov no. Thaum BiblioPixel tau teeb tsa koj yuav tsum muaj peev xwm khiav cov animations yam tsis muaj teeb meem.
