Garland LED tus kheej ob txhais tes: tswvyim hais ua dabneeg los yog kev muaj tiag?

Thawj garlands - ib qho ntawm cov kev kho cov chav uas yog cozy thiab festive mus ob peb vas. Ob peb cov neeg paub hais tias tus garland LED, nrog nws tus kheej ob txhais tes ua, - nws yog yooj yim workable. Koj yuav tsum tau tsim ib qho kev xaiv uas yuav nplua koj thiab fits txig rau hauv lub sab hauv.

Yuav ua li cas yog cov garlands

Nyob rau hauv lub rhawv koj yuav nrhiav tau ib tug ntau ntawm txawv xaiv, nyob rau hauv thiaj li tsis mus tau poob nyob rau hauv tag nrho cov ntau yam koj yuav tsum paub yuav ua li cas lawv ua hauj lwm thiab dab tsi yog qhov txawv. Paub txog hais tias xws li ib tug tswvyim ntawm LED garlands, yuav pab koj yog hais tias koj txiav txim siab mus ua koj tus kheej.

Hom ntawm cov hlua:

1. Tsoos garland thread.
2. ntxaij garland.
3. Kub hnyiab tau.
4. Ib tug ntawm cov variants ntawm tus kab hlau rhuav - garlands, icicles.
5. Dyurolayt.
6. Kiplayt.
7. Stroblayt yuav tsim flicker.

Tam sim no uas koj tau txiav txim siab rau tej yam kev garlands, yuav tsum tau tsim los ntawm koj ua tib zoo xyuas cov nyob ntawm tej thiab tej yam zaub mov uas yuav siv tau los tsim garlands nrog lawv ob txhais tes.

Hom ntawm cables thiab lub hwj chim mov

Niaj hnub nimno garlands tau siv ib tug ntawm peb hom hlau. Yuav kom qhov no roj hmab, silicone thiab PVC ntaub ntawv tej zaum yuav siv tau. Rau sab nraum zoov decorations yog siv thawj ob hom ntawm nyob ntawm tej, raws li lawv muaj siab mus-resistant thiab txaus resistant rau kub hloov. Nyob rau hauv thaj chaw, koj muaj peev xwm siv nyiaj txiag LED Christmas garland nrog PVC hlau.

Raws li lub hom zaub mov ib tug yuav paub qhov txawv ob hom: siv yooj yim thiab hluav taws xob. Tus thawj yog zoo tagnrho rau cov kho kom zoo nkauj ntawm facades thiab qhov chaw nyob qhov twg nws yog tsis yooj yim sua rau coj hluav taws xob. Cov garlands LED txoj kev khiav rau roj teeb. Vim cov uas tsis muaj zog noj yuav ua hauj lwm ib tug ntau lub sij hawm. Ib tug loj ntxiv rau cov kev mus ncig, lawv tau yooj yim nrog koj nyob promotions. Hluav taws xob cov plug nyob rau hauv lub nplos.

Option 1: Tsim ib tug garland ntawm cov laus keyboard

Yuav ua li cas tshwm sim yog hais tias lub garland yog tsim nyog nyob rau hauv lub shortest tau lub sij hawm, thiab nyiaj txiag mus yuav nws muaj. Ces tuaj rau cov kev pab rhiav "Garland LED, tau nrog nws tus kheej txhais tes." Xav txog cov feem ntau cov nyiaj txiag kev xaiv rework qub computer chaw ua hauj lwm cov khoom, xws li cov twj remote controls thiab nas.

Yuav kom ua tau lub chaw ua hauj lwm yuav tsum tau:

• Ob peb ruaj keyboard (koj yuav tsis ua hauj lwm).
• Soldering hlau.
• Resistors.
• Hluav taws xob cov kab xev.
• Tube-end tes tsho Ntsws.
• Los yog rosin flux.

Ua ntej peb yuav tsum tshem tawm cov keyboard los ntawm ntau yam ruaj nyob ntawm tej thiab maj mam muab disconnect tus USB-cable. Yuav kom Festoon LED, tau nrog nws tus kheej txhais tes, nws yog ib tug high-qib, yuav tsum tau saib rau ib tug tsawg kawg nkaus ntawm tsib keypads. Nug ib ncig nrog cov phooj ywg, cov phooj ywg, los yog mus rau lub zos forums. Txhua muaj tsawg kawg yog peb LED qij uas yuav pab tau raws li kev ntsuas ntawm qhov hais kom ua nyees khawm. Yog hais tias lub Tshuag yog ruaj gamer, tus nqi nws yuav tsis, vim hais tias muaj sib sau ib tug loj tus naj npawb ntawm LEDs. Cov feem nthuav kev xaiv yog tau los ntawm nws txawv qhov muag teeb los ntawm ntau yam chaw ua hauj lwm cov khoom.

qhia

Rho thiab tshem tawm cov keyboard los yeej muaj ib tug nqi me me rau cov maub los. Hais tias nws yuav mus txuas ntxiv los yuav soldered mus rau lub teeb. Nws yog ib qho tseem ceeb yuav tau nco ntsoov tias txhua yam garland LED (ua rau lawv tus kheej txhais tes) yog muaj li ntawm 12 ntsiab, uas yog kev cob cog rua nyob rau hauv uas tig mus rau lub resistors. Yog hais tias peb xav txog hais tias ib tug dog dig USB muab ib tug voltage ntawm 5 volts, thiab tam sim no lub dag lub zog ntawm 500 ma.

Lub ntuj nro ntawm txhua lub caij tsis pub tshaj 5 volts. Yog hais tias koj txuas ncaj qha, lawv yuav overheat thiab kub sai sai. Nws yog tsim nyog los txo qhov nro. Qhov no yuav ua tau los ntawm pairwise soldering ntsiab. Yog li, txhua yam uas lawv yuav txo rau lwm yam. Tab sis qhov kev xaiv no yog tsis pom. Nws yog qhov zoo tshaj plaws los mus siv ib tug tej yam voltage lub moj khaum uas yuav tsis ua txhaum rau lub riot ntawm multi-kob teeb.

Siv lub qaum thiab hlawv ib tug me ntsis braid rau ntawm ib sab. Nyob rau hauv lub liab qab qhov rais solder. Yog li ntawd koj yuav tsim rau lawv tus kheej txhais tes LED Festoon yuav tsum tau ntev. Luag xav zoo lawm, ntev thiab insulate lub raug qhov chaw. Hauv lub cable tub ntxhais noj rho tawm - Dub, plus - liab. Txuas rau tag nrho cov qauv thiab pib mus kuaj LED txoj kev garlands.

Kev Xaiv 2: Tsim ib tug garland los ntawm kos

Yog hais tias koj xav mus ua ib qho kev nthuav garland uas yuav ua tau raws li qhov kev cai tswjhwm yuav tsum tau, ces thov nyeem daim duab hauv qab no. Tsav LED garlands cia pom mus rau hauv tus txheej txheem thiab to taub nyob rau hauv kom meej lub theem ntawm tag nrho cov ntsiab.

Nyob rau hauv cov ntaub ntawv uas, yog hais tias peb xav txog qhov tau thaum muaj xwm ceev kev cai zaus ntawm lub multivibrator raws li ib tug tshwm sim ntawm shear rau lub xaus ntawm tag nrho cov muaj nyob rau transistors, nws begs rau lo lus nug ntawm lub complexity ntawm lub hloov teb thiab bipolar transistors. Nyob rau hauv cov ntaub ntawv no nws yog tsim nyog los xav txog lub zaus ntawm switching, yog hais tias tus txo lub sij hawm, lub LEDs rau lub garland, yuav hloov sai heev.

Yog li ntawd siv VT-1 thiab VT-2 tej zaum yuav zoo ib yam li thiab KTZ101 KTZ15. Yuav kom txiav txim seb qhov voltage thiab nws nco nyob rau lub LED txoj hlua, koj siv tau cov R2 transistor.
