Tib neeg ib txwm tau nyiam los ntawm cov sawv cev holographic. Muaj ntau txoj hauv kev los ua qhov no.
Hauv kuv qhov haujlwm kuv siv cov hlua txuas ntawm LED strips. Muaj tag nrho 144 LEDs uas tuaj yeem nthuav qhia 17280 voxels nrog 16 xim. Cov voxels tau teeb tsa ncig hauv 12 qib. Cov LEDs raug tswj los ntawm tsuas yog ib lub microcontroller. Vim tias kuv tau siv APA102 LEDs kuv xav tau tsis muaj tus tsav tsheb ntxiv lossis transistors. Yog li cov khoom siv hluav taws xob yooj yim dua los tsim. Lwm qhov zoo dua yog kev siv hluav taws xob wireless. Koj tsis xav tau txhuam thiab tsis muaj kev sib txhuam poob.

Parallax Propeller Microcontroller:
Tsis txhob ntshai ntawm lub microcontroller no, nws muaj zog 8-core mcu nrog 80Mhz thiab tsuas yog yooj yim rau program/nyem raws li arduino! Muaj ntau lub Rooj Tswjhwm Saib ntawm lub xaib parallax muaj.
Lwm qhov (kuv) xaiv yog CpuBlade/P8XBlade2 los ntawm cluso, microSD nyeem ntawv nyob ntawm lub nkoj thiab lub binary yog khau raj yam tsis muaj lub program!
Txog rau kev tsim cov kiv cua thiab tseem qee cov arduinos koj yuav xav tau USB rau TTL adapter board.
Cov cuab yeej kuv siv:
- Riam
- soldering chaw nres tsheb thiab cov laug
- rooj laum 4+5 hli driller
- shearing thiab rasp/ntaub ntawv rau lub breadboards
- ntsia hlau ntswj 7+8+10 hli
- hex ciaj ntswj 2,5mm
- rauj + nruab nrab punch rau kos lub qhov rau lub cav ntawm lub phaj hlau
- lub rooj ntev zaum rau khoov cov hlau phaj u-puab

- kub yaj yaj phom
- ob peb pliers, sab txiav
Kauj Ruam 2: 3D Luam Qhov Chaw
Ntawm no koj tuaj yeem pom cov ntu kuv luam tawm los ntawm PLA. 12 daim yuav tsum tau los ntawm tus spacer. (Ntu thib peb). Qhov ntu no tsim lub kaum sab xis ntawm LED cov laug cam.
Kauj Ruam 3: Wireless Fais Fab thiab Tsav Tsheb
Hauv cov kauj ruam no kuv qhia koj txog kev siv wireless. Cov coils no feem ntau yog siv rau them lub xov tooj ntawm tes. Cov tswv yim hluav taws xob yog 12V, tso tawm 5V. Qhov no zoo tagnrho rau peb cov helix. Qhov max. tam sim no yog kwv yees li 2A. 10 Watt yog txaus rau LEDs. Kuv tsis siv qhov ci ci tshaj plaws ntawm LEDs thiab tsis hloov rau txhua lub LEDs tib lub sijhawm.
Ib qho tseem ceeb tshaj plaws, siv lub rhaub dej kub rau thawj kauj PCB vim tias nws kub heev! Kuv kuj siv lub kiv cua me me kom txias lub rhaub dej.
Raws li koj tuaj yeem pom kuv siv cov phaj hlau ua ntej rau kev txhim kho lub cev tab sis koj tseem tuaj yeem khoov ib lub phaj (alu). Siv li 60x60mm rau sab saum toj thiab 10x60mm rau sab vaj huam sib luag. Tsis tas li ntawd kuv txuas lub phaj rau ntawm cov ntoo hnyav.
Kauj Ruam 4: Lub Cev Muaj Zog/Tswj
Nov yog qhov schematic yuav ua li cas tswj lub cav. Kuv siv cov arduino nrog tus lej nkag rau qhov nrawm thiab pib/nres khawm. Daim duab kos ntawm arduino kuj tau txuas nrog. Txhawm rau ua haujlwm rau arduino saib ntawm ntau cov lus qhia ntawm no ntawm kev qhia:-)
Lub cav tsis txhuam yog me me 50g yam uas tshuav lawm. Kuv rov hais dua lub cav loj dua me ntsis.
Kauj Ruam 5: Helix
yog ua los ntawm 12 kab txaij/veroboard, lub qhov taub 5 hli tau muab hlais hauv plawv. Nco ntsoov tias muaj tsawg kawg 4 kab tooj liab nyob tom qab. Cov hlua tooj liab sab nraud tau siv los txhawb lub zog LED strips. Cov hlua tooj liab sab hauv yog rau DATA thiab CLOCK thiab cais rau ob sab. Ib sab ntawm lub rooj tsavxwm yog tus txawm thiab ib sab yog qhov khib rau Pixels. Tag nrho muaj 4 pawg 36 LEDs. Cov 36 LEDs no tau sib cais hauv 6 tus hauv thawj 6 qib. Yog li muaj qhov sib npaug/khib thiab sab saum toj/hauv qab pab pawg.
Kauj Ruam 6: Helix Schematic
Cov txheej txheem siv cov laus thiab loj dua fritzing MCU-board vim tias kuv tsis pom fritzing templates ntawm tshiab/tam sim no Propeller Boards.
Rau LED-tswj kuv siv Tus Kws Tshaj Tawm Microcontroller los ntawm Parallax. Ob Pins ntawm micro tswj 6x6 = 36 LEDs. Yog li lawv yog 4 pawg LED (txheej txheem), los ntawm saum toj no:
- txawm/hauv qab
- khib/hauv qab
- khib/top
- txawm/top
Software tau txuas nrog, saib ntawm kuv cov lus qhia yav dhau los (qib 4) rau kev ua haujlwm rau Propeller Microcontroller.
Kauj Ruam 7: Cov Voxels tau npaj li cas
Hauv daim ntawv no koj tuaj yeem pom tias cov voxels tau npaj li cas.
120 thav ntawv tau tsim tawm ib zaug. Txhua tus ncej muaj 12x12 = 144 Voxels, uas muab rau peb tag nrho 120x144 = 17280 Voxels. Txhua Voxel tau txais 4 ntsis rau xim yog li peb xav tau 8640 bytes ram.
Kauj Ruam 8: Cov Lus Qhia Ntxiv
Nco ntsoov tias lub helix tig lub moos tig rov qab!
Nws yog ib qho tseem ceeb heev kom sib npaug cov helix nrog cov khoom sib tw ua ntej tig. Siv cov iav tiv thaiv thiab ntau cov kua nplaum rau qhov uas tuaj yeem "ya mus".
Qhov kev ncua deb ntawm "Prop ntug" yog 21mm (yog lub rooj tsavxwm muaj 160mm), tus tim tswv: 15 degree
Hloov tshiab:
- (Tsib Hlis 2, 2017), kho qee cov duab nrog cov lus piav qhia
- (Tsib Hlis 3, 2017), ntxiv cov kauj ruam: Cov Voxels tau npaj li cas
