Christmas tsis zoo ib yam yog tsis muaj tsob ntoo Christmas; tab sis lub nroog Yeiuxalees Kuv nyob hauv chav pw, Kuv tsis muaj qhov chaw tso qhov tiag. Yog li ntawd yog vim li cas kuv thiaj txiav txim siab los ua kuv tus kheej tsob ntoo Christmas xwb!
Kuv tau xav sim nrog ntug lit acrylic rau ib pliag tam sim no, thiab qhov no zoo li yog qhov haujlwm zoo los sim nws.
Lub tswv yim yog tias koj ua lub teeb ci rau ntawm ntug, thiab nws cuam tshuam rau ib qho tsis zoo (khawb lossis kos duab) hauv acrylic; yog li teeb lub plexi. Kuv xav mus ib kauj ruam ntxiv thiab ua kom nws muaj ob xim: tsob ntoo ntsuab, nrog lub hnub qub liab nyob saum!
Wb tau tsev!
Kauj ruam 1: Qhov & Cov Cuab Yeej
Qhov
- Acrilic (PMMA / Plexiglas) ntawv
- Ntsuab LED 5 hli x4
- 82 Ohm resistor x4
- LASER liab taw qhia
- Micro USB breakout board lossis USB cable
- Prototyping board
Cov cuab yeej
- Soldering Hlau
- Laum
- Sandpaper (ntxhib daim phiaj)
- 3D tshuab luam ntawv (rau lub hauv paus)
- Laser txiav (rau acrylic)
Kauj ruam 2: Electronics
Txhawm rau teeb lub acrylic, peb yuav xav tau qee yam - koj twv nws - teeb! Peb yuav siv ob qho tib si LEDs ntsuab thiab LASER xim liab rau qhov ua kom pom xim ob.
Lub tswv yim yog tias LEDs yuav ci rau hauv qab ib feem ntawm tsob ntoo, thaum lub laser yuav npog rau sab saum toj, txij li lub nqaj tau tsom mus ntau dua.
Pib los ntawm kev txiav ib daim ntawm daim ntawv xaum 13x13 pawm thiab tho qhov 12 hli nyob hauv nruab nrab. Tom qab ntawd ntxig 4 LEDs rau hauv lub qhov thiab muab lawv tso rau hauv qhov chaw. Lawv yuav tsum tsis txhob kov lub perfboard, tab sis hover txog 2 hli saum nws.
Nws yog lub sijhawm tam sim no txhawm rau ntxiv qhov txwv tam sim no rau cov LEDs, uas tuaj yeem suav los ntawm Ohms txoj cai:
R = U/IR = (USB voltage - LED voltage)/LED currentR = (5V - 2.5V)/30mAR = 82 Ohm
Solder tus resistor mus rau sab tsis zoo ntawm LED, thiab txuas rau lwm tus coj ntawm tus tiv thaiv hauv lub voj voog.
Sib nrug ib qho pheej yig tus pointer laser thiab tshem tawm LASER module nws tus kheej (qhov no tseem suav nrog lub lens). Kuv muaj cov hlau hlau, uas tau tshwm sim los ua qhov dav dav. Peb tam sim no tuaj yeem tso lub LASER module rau hauv lub qhov thiab khoov qhov ua tau zoo ntawm LEDs rau nws.
Ua kom tiav los ntawm kev txuas qhov zoo thiab tsis zoo ua rau lub micro USB breakout board. Kuj sim yog txhua yam teeb raws li qhov xav tau.
Kauj Ruam 3: Tsim Kho Txhua Yam
Tam sim no tias peb muaj cov khoom siv hluav taws xob tawm ntawm txoj kev, peb yuav ua qhov khoom uas yuav ua rau pom kev.
Txiav daim ntawm 3 hli acrylic. Yog tias koj muaj kev nkag tau rau mat acrylic, qhov ntawd yog txoj hauv kev yooj yim tshaj plaws. Txwv tsis pub, coj acrylic ntshiab thiab xuab zeb saum npoo zoo li nws dhau los ua mat thiab yuav ua rau lub teeb ci.
Xaub ob daim ua ib leeg thiab haum lawv hla cov LEDs. Qhov no yooj yim tshaj plaws ua nrog cov lus tsa suab. Qhwv qee daim kab xev dub nyob ib puag ncig cov LEDs kom muaj lub teeb ci.
Cov kauj ruam tom ntej yog teeb tsa lub hauv paus. Luam tawm ob ntu; ceev faj: lawv tau sib txawv ntawm ib leeg, tsis txhob luam tib yam ob zaug. Tam sim no ntxig lub rooj sib dhos uas peb tau ua ua ntej rau hauv paus.
Qhov ntawd yog txhua yam rau nws!
Kauj Ruam 4: Xeem & Txaus Siab
Peb ua tiav! Tib qho uas yuav tsum tau ua yog sim peb tsob ntoo Christmas tshiab.
Ntxig lub micro USB cable rau hauv tsob ntoo thiab txaus siab rau lub teeb pom kev zoo! Thaum nws tsis yog tsob ntoo loj, nws paub tseeb muab qee qhov Christmas vibe:)
