Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntau yam nyob ib puag ncig peb. Lawv nyob ib sab ntawm peb: tom haujlwm, tom tsev, thiab hauv tsheb. Cov neeg tsim khoom muab lawv cov kev xaiv rau txhua lub sijhawm. Tab sis tsis muaj kev txwv rau kev npau suav, thiab cov neeg ua haujlwm nyiam ua haujlwm tau tuaj nrog ntau ntawm lawv. Cov khoom siv no tuaj yeem siv rau ntau lub hom phiaj thiab ntau qhov chaw, thiab ntau yam ntawm lawv tsuas yog amazing.
Schemes ntawm cov khoom siv hluav taws xob hauv tsev rau ob qho tib si pib thiab cov kws ua haujlwm paub txog tuaj yeem pom muaj ntau hauv cov ntawv tshwj xeeb. Tab sis ntawm ntau yam, koj tuaj yeem xaiv qhov nthuav tshaj plaws. Yog li ntawd, hauv tsab xov xwm no peb yuav qhia txog qee qhov piv txwv ntawm cov khoom siv no.
Kev txav chaw sensor
khoom siv hluav taws xob hauv tsev yog tsim los ua kom lub neej yooj yim dua rau tib neeg. Ntawm lawv yog txhua yam ntawm cov sensors uas tso cai rau koj los tswj lub tsev nyob deb. Ib qho piv txwv zoo li no yog lub suab sensor.
Lawv ua haujlwm raws li kev xav ntawm kev xav. Yog tias koj nkag mus rau thaj chaw tswj hwm, lub zog impulse yuav tshwm sim, thiab nws cov yam ntxwvyuav hloov. Qhov no yuav kho tus ntes uas saib xyuas cov zis.
Rau lub tsev, nws yog qhov zoo dua los xaiv lub ntsuas cua sov, vim tias nws cov khoom pheej yig dua. Cov txheej txheem sib dhos tsis ua rau muaj teeb meem (nws tau qhia hauv daim duab hauv qab no). Yog, thiab cov cuab yeej zoo li no tuaj yeem ua haujlwm hauv ntau qhov kub thiab txias. Lub sensor no haum rau kev tswj lub teeb, tswb thiab lwm yam.
Hloov lub teeb ci LED
Cov roj teeb muaj nyob hauv txhua lub tsev. Tab sis tam sim no lawv tau maj mam raug thawb tawm ntawm kev ua lag luam. Lawv tau hloov los ntawm LED teeb pom kev zoo, yog li muaj cov kev xaiv rau kev hloov cov teeb incandescent mus rau cov niaj hnub thiab kev lag luam ntau dua. Ua li no, koj xav tau 30 W LED matrix, aluminium ntawv, profile. Pib:
- Ua ntej, lub teeb yuav tsum tau disassembled.
- Tom ntej no, ib lub voj voog raug txiav tawm ntawm daim ntawv txhuas, sib npaug ntawm nws txoj kab.
- Ob daim me me ntawm qhov profile raug txiav tawm ntawm nws. Lawv txuas nrog rivets perpendicular rau ib leeg. Lawv qhov loj me yuav tsum zoo li haum rau hauv lub teeb ntxoov ntxoo.
- Ntawm lub voj voog txhuas, kos cov npoo ntawm LED matrix (nws yuav tsum muab tso rau hauv qhov chaw).
- Ua qhov rau rivets thiab kho cov matrix.
- Los ntawm sab hauv peb kho qhov profile. Nws yuav ua haujlwm ntxiv los txhim kho cov cua sov.
- theem kawg suav nrog kev teeb tsa ntawm cov qauv hauv qab nthab. Nws yog ib qho tsim nyog los txuas lub teeb xaim rau cov xov hlau matrix. Tom qab ntawd, lub teebkaw.
Cov khoom siv hluav taws xob hauv tsev no npaj siv ntxiv.
LED backlit tile
Cov khoom siv hluav taws xob hauv tsev ua rau lub tsev xav tsis thoob nrog lawv ntau yam thiab kev sib tw ntawm kev xav ntawm cov tswv uas tau tsim lawv:
- txheej txheem pib nrog kev tso cov vuas raws li kev cai. Tsuas yog cov seams nruab nrab ntawm cov vuas tsis tas yuav tsum tau muab kaw.
- theem tom ntej ntawm kev ua haujlwm yog kev npaj cov xaim. Rau qhov no, kev sib txuas tshwj xeeb ntawm hom "txiv-niam" yog siv. Cov hlau yuav raug insulated nrog cua sov shrink. Cov ntsiab lus ntoo khaub lig tau ntxiv rau cov xaim, uas hauv lawv cov qauv tsim muaj LED.
- Thaum tag nrho cov xaim sib sau ua ke, nws yuav tsum tau muab tso rau hauv qhov grooves ntawm cov vuas. Nws yog qhov zoo tshaj rau nruab lub LED ntawm kev sib tshuam ntawm cov seams.
- Tom qab txhua yam tso tawm, koj tuaj yeem pib sau cov pob qij txha nrog fugue. Tsuas yog hauv qhov no koj yuav tsum tau ceev faj heev kom tsis txhob txav cov LEDs.
Glowing balls
Balloons yog tus cwj pwm nyiam ntawm txhua hnub so. Lawv tau nyob ib puag ncig ntev heev. Tab sis tsuas yog tsis ntev los no lawv "lub neej" tau hloov nrog qhov sib ntxiv ntawm "zest". Qhov tseeb yog tias cov khoom siv hluav taws xob hauv tsev tau cuam tshuam rau lawv thiab. Cov pob ci ntsa iab yuav kos xim rau lawv tus kheej. Nws tsis nyuaj ua rau lawv. Ua li no, koj yuav xav tau: balloons nyob rau hauv tus nqi ntawm 5-10 daim, roj teeb, ntawm tus nqi ntawm 3 daim rau txhua lub balloon, thiab daim nplaum nplaum.
- Cov txheej txheem pib los ntawm kev tshuaj xyuas qhov polarity ntawm LED. Ua li no, nws muab tso rau ntawm lub roj teeb. Yog hais tias nws taws, ces txhua yam yog lawm. Yog tsis yog, koj yuav tsum tau hloovpolarity.
- Tom qab ntawd, LED txuas nrog lub roj teeb nrog cov nplaum nplaum. Cov tsim tsim tau muab tso rau hauv ib lub pob. Tib txheej txheem yog ua nrog tag nrho cov khoom seem.
Cov khoom siv hluav taws xob hauv tsev no rau cov pib tshiab tsim nyog. Yuav luag txhua tus tuaj yeem ua tau.
Hnub-hmo yees duab relay
Lub teeb uas tig rau thiab tawm ntawm nws tus kheej yooj yim heev. Electronic homemade schemes muab los ua photorelay. Lub photodiode tuaj yeem coj los ntawm lub computer qub nas.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm yog qhov yooj yim heev. Nws yog ib qho tsim nyog yuav tsum tau sib sau ua ke hauv Circuit Court, raws li qhia hauv daim duab. Nws yog haum rau lub ntees thaum lub teeb. Thaum lub teeb los ntawm LED hits lub photodiode, lub transistor qhib. Qhov no ua rau lub LED thib ob kom teeb. Lub rhiab heev ntawm lub cuab yeej hloov nrog lub resistor.
Kev siv hluav taws xob hauv tsev - qhov no yog tag nrho lub ntiaj teb uas tsis muaj tseeb tiag kom paub. Koj tuaj yeem xaiv tsuas yog ob peb txoj kev xaiv uas haum rau txhua rooj plaub tshwj xeeb. Thiab yog tias tsis muaj dab tsi tsim nyog, koj tuaj yeem tuaj nrog qee yam ntawm koj tus kheej thiab qhia rau lwm tus.
