Txog hnub so, kuv xav muab ob peb tus phooj ywg ua qhov txias, los ntawm lub sijhawm ntawd kuv tau qhia kuv tus kheej txoj kev xav yooj yim Circuit Court thiab tau txaus siab nrog LEDs.

Yog li, Kuv xaj LEDs ob lub lis piam txij Christmas, xav tias qhov no yuav yog lub sijhawm txaus rau kev xa khoom thiab tsim khoom. (Kuv yuav 200 LEDs rau tus nqi pheej yig $ 12 ntawm e-bay los ntawm cov khoom siv hluav taws xob) Hmoov tsis zoo, nws siv sijhawm ob lub lis piam xa los ntawm Hong Kong, thiab kuv tau txais cov LEDs nyob rau hnub Christmas. Tam sim no nws lig me ntsis, zoo li Christmas tau txog 5 hnub dhau los, tab sis lawv yog qhov khoom plig zoo me me rau yav tom ntej. Thiab ntxiv rau, Kuv tseem yuav muab rau ob peb tus neeg rau xyoo no;-) Qhov no yog kuv thawj Kev Qhia thiab kuv vam tias koj nyiam nws.

Kauj Ruam 1: Sau Cov Khoom

Koj yuav tsum tau:

Tooj Tooj Hlau 19 LEDs (koj tuaj yeem siv ntau xim, Kuv siv ntsuab, xiav, liab, thiab dawb) Liab: 2.7 v @ 13mA Ntsuab: 3.2 v @ 10 mA Xiav: 3.2 v @ 10 mA Dawb: 3.2v @ 10 mA Resistors: 390 ohm X 4 330 ohm X 2 aluminium sheet Solder ntsuab xaim USB cable ntoo (nyiam dua ncig, 1 nti txoj kab) ob lub txiv laum huab xeeb lub thawv lub kaus mom paj rwb pob (xaiv tau) daim ntaub ci (nyiam dua) kub kua nplaum Cov cuab yeej: Soldering Hlau Tin Snips Clamp Propane Torch Pliers Diagonal cutters wire stripper (yog tias koj xav tau, kuv siv cov hniav) dremel cuab yeej Chop pom laum laum khoom

Kauj ruam 2: Kauj ruam 1

Txhawm rau ncaj cov hlau tooj liab, tsuas yog clamp nws nyob nruab nrab ntawm ob daim ntoo loj, tom qab ntawd tig cov hlau kom txog thaum nws ncaj ncaj.

Tom qab ntawd, nrog cov xaim xaim hauv qhov clamp, siv lub teeb hluav taws xob propane txhawm rau ua kom sov cov hlau, tom qab ntawd muab ib txoj hlua txuas txuas li ob ntiv tes los hauv qab ntawm cov xaim. (Kuv tsuas yog siv daim duab thib ob uas kuv tau ua, yog li daim npog cua sov twb muaj lawm) Thaum koj ua qhov no, khoov ib qho ntawm koj lub hauv paus xim LEDs 'cathode txog 3 hli los ntawm qhov kawg thiab muab nws pov rau. Tam sim no, koj yuav tsum muaj peev xwm tuav lub LED kom cov kab nkhaus nkig nrog cov xaim, thiab sai sai yaj ob qho tib si ntawm cov hlau lead thiab qee yam ntawm cov laug ntawm cov xaim. Nco tseg: koj yuav tsis tuaj yeem yaj tag nrho cov kab laug sab ntawm cov xaim, vim tias cov tooj liab tooj liab rub cov cua sov tawm ntawm nws.

Kauj Ruam 3: Ua 1st Ntiv Nplhaib

yog li, koj muaj koj thawj LED rau, tam sim no kuv yuav lo rau cov xim coj (ntsuab rau kuv), thiab tso lwm 7 rau hauv qab kab. (tag nrho = 8) Tsis tas li ntawd, tsis txhob hnov qab khoov Anode sab laug lossis sab xis, nws tsis muaj teeb meem dab tsi, tab sis koj yuav tsum tau ua raws cov lus qhia ntawd rau tas li ntawm lub suab nrov, npaj cov coj ua tib yam nkaus koj tau ua lwm yam, khoov cov cathode tib yam, tinning nws, thiab muab nws txuas rau xaim. NCO NTSOOV: Kho txhua qhov hauv tib txoj kev coj rov ua dua qhov no kom txog thaum koj muaj lub nplhaib ntawm 8 (ntsuab) LEDs Tom qab ntawd muab qhov chaw sib npaug tawm tag nrho cov LEDs hauv lub nplhaib, anodes yuav sib tshooj- qhov no yog qhov zoo tshaj plaws hauv txhua qhov anodes saum, mus ncig hauv lub voj voog, tom qab ntawd muab lawv txhuam rau cov anodes hauv qab lawv.

Kauj Ruam 4: Ua Lub Nplhaib thib 2

Tam sim no, koj yuav tsum tau muab tso rau lwm lub nplhaib ntawm cov laug, kwv yees li 3/4 deb ntawm thawj lub nplhaib, tab sis cov LEDs nyob ntawd thiab koj tsis xav kom lawv yaj, puas yog?!

Ua kom koj cov txhuas thaiv cua sov siv qee qhov txhuas, tin snips, thiab 300 mana cov ntsiab lus txiav ib lub xwmfab, lub voj voog, lossis ib qho euclidean geometric shape loj txaus los tiv thaiv cov LEDs thiab txiav tawm qhov hlais rau hauv nruab nrab ntawm nws nrog cov snips. plam daim ntaub thaiv ntawm cov hlau tsuas yog tom qab thawj lub nplhaib thiab nqa lub teeb! Ua lwm lub nplhaib ntawm cov xaim, thiab npaj koj cov LEDs. TAB SIS: Lub sijhawm no, koj siv 6 LEDs, Kuv hloov xim, siv koj lub hauv paus xim thiab qee qhov ntxiv (Kuv siv ntsuab thiab xiav). Tsis tas li, koj yuav tsum ua kom cathodes luv dua lub sijhawm no, yog li khoov cov cathodes kom tsim nyog hauv, tej zaum ib nrab txoj kev lossis 1.5 cm ze rau lub taub hau. NCO TSEG: xyuas kom koj txheeb xyuas qhov hluav taws xob thiab qhov sib txawv ntawm ob lub xim sib txawv LEDs Qhov no yog qhov tseem ceeb vim tias yog muaj qhov sib txawv loj, tom qab ntawd koj yuav tsum tau khiav kab xaim sib txawv rau cov xim LED ntawd, thiab tsuas yog muab cov LEDs sib dhos nrog lawv tus kheej thiab tsis yog lwm cov LEDs

Kauj Ruam 5: 4th thiab 5th Ring

Lub sijhawm no koj yuav rov hloov qee qhov xim nrog lub hauv paus xim (Kuv tau liab & ntsuab)

Rau lub nplhaib thib 4 koj tsuas yog siv 4 LEDs, thiab ua rau cov hlau lead luv heev, tej zaum 1.5 cm tag nrho hauv qhov ntev Okay, koj paub laum: thaiv cua sov -> PROPANE -> solder -> npaj LEDs -> solder LEDs -> solder anodes ua ke NCO TSEG: koj yuav hais tias "Tab sis koj hais tias qhov liab liab yog 2.7 thiab ntsuab yog 3.2, koj tau ua dab tsi?!" zoo, Kuv tau siv ob lub LED ntsuab nyob ua ke thiab ob lub teeb liab LED nyob rau hauv tib lub sijhawm, tom qab ntawd kuv yuav siv cov xov hlau tsuas yog rau cov liab thiab cov zaub ntsuab yuav txuas rau ntawm tsob ntoo zoo li tam sim no! Qhov kawg "RING"! Qhov no tsis yog lub nplhaib tiag tiag. Siv cov khoom siv me me thiab cov txiv neej POWER, txiav cov xaim li 1/4 hauv los ntawm lub nplhaib thib 4, tom qab ntawd qhwv cov cathode, thiab muab nws txuas mus rau lub nplhaib thib plaub lub cathodes/ lub nplhaib sib dhos nyob ntawd. koj tuaj yeem hloov qhov siab ntawm "ntiv nplhaib" thib 5 rau txhua yam koj xav tau. Kuv khaws qhov siab hloov pauv tas li. Kuv hais kom qhwv cov anode hauv lub voj voog ncig cathode, txoj hauv kev no txhua lub xov hlau ntsuab yuav yooj yim rau sab laug rau saum. Kuv kuj siv cov coj dawb, rau cov ntsiab lus txias txias!

Kauj Ruam 6: Txuas tsob ntoo

Yog lawm, yog li tsob ntoo tau tsim, thiab tam sim no txhua yam koj yuav tsum tau ua nws txuas nws mus rau USB cable, thiab ntsaws qhov nqus no.

Ua ntej, koj yuav tsum tau txais tag nrho cov ntsuab thiab xiav LEDs ua ke. Raws li tam sim no, muaj 8 zaub ntsuab nyob rau hauv qab (lub nplhaib hauv qab), 3 zaub ntsuab thiab 3 blues ua ke (lub nplhaib thib ob), thiab 2 zaub ntsuab ua ke (lub nplhaib thib peb). Txhawm rau kom lawv txhua tus sib koom ua ke, koj yuav tsum tau dhia qee cov xov hlau los ntawm anodes ntawm txhua lub nplhaib mus rau anode ntawm qhov txuas ntxiv. Nco tseg: koj yuav xav ua cov kev sib txuas zoo li tsob ntoo Christmas, raws li txoj kab nkhaus ib txwm pom hauv cov duab ntoo Christmas, qhov no yooj yim heev ua. Tam sim no, koj tseem tuaj yeem ntxiv ntau qhov kev sib txuas no kom ua tau ntau ntawm "Christmas nkhaus" nyob ib ncig ntawm tsob ntoo. Lub teeb los ntawm LEDs yuav tsum ua xim rau lawv tom qab, yog tias koj tsis muaj cov hlau ntsuab tso ib puag ncig. (Kuv siv Hard Drive cable) Tom ntej no, nqes hlau xaim mus rau qhov liab LEDs 'anode, thiab nab nws mus rau hauv qab ntawm tsob ntoo. Cov xaim no yuav muaj nws tus kheej tiv thaiv. Thaum kawg, nqes White LED tus hlau, thiab zoo li cov kauj ruam dhau los, nab nws nqes mus rau hauv qab. Cov xaim no tseem yuav tau txais nws tus kheej tiv thaiv.

Kauj ruam 7: USB SIJHAWM

Coj tus txiv neej USB cable thiab hle qhov kawg ntawm nws, koj yuav tsum pom cov xov tooj liab thiab dub, thiab ob lub xov tooj uas muaj xim sib txawv. Txiav tawm ob lwm cov xov hlau xim, cov no yog rau cov ntaub ntawv hloov chaw thiab peb tsuas xav tau POWER! USB yuav muab 5V @ 100 mA, yog li yog tias koj tsis siv tib lub LEDs ib yam li kuv, koj tuaj yeem suav qhov tiv thaiv tus nqi xav tau nrog OHM's LawNow, peb yuav tsum ua peb cov neeg tawm tsam…. Txhawm rau kom tau txais tus nqi raug nrog qhov kuv tau dag nyob ib puag ncig lub tsev, Kuv yuav tsum tso ob lub resistors ua ke. Yog tias koj siv LEDs sib txawv dua li kuv, thiab xav tau qhov sib txawv, siv cov qauv no: R3 = (R1*R2)/(R1+R2) Kuv xav tau ob 178 ohm resistors thiab ib qho 200 ohm resistor (Kuv paub tias 390/2 = 195, tab sis nws ze txaus) Tam sim no, muab ib qho ntawm 390s ua ke nrog ib qho ntawm 330's thiab ua ob qho ntawm R3'sNext, muab ob 390's ua ke ua ke kom ua rau 195 ohm resistor Siv peb qhov kev ntsuas resistors (178, 178, thiab 195 ohm) thiab muab tag nrho cov hlau lead ntawm ib sab ua ke, yog li ntawd lwm sab tuaj yeem txuas rau 3, cais cov xov hlau. Ua tus tiv thaiv "pob" me me li sai tau. (saib hauv daim duab, nws nkag siab yooj yim dua) Txiav tawm txhua qhov ua rau sab uas koj tau muab pov tseg tag nrho ua ke Tam sim no, nrog txoj hlua rub tawm thiab lub + thiab - xov hlau raug tshem tawm ib yam, xaim cov xov hlau thiab txuas liab xaim (+) rau tus tiv thaiv "pob" ntawm qhov kawg uas txhua qhov peb tiv thaiv tau txuas nrog. Tsis tas li, txuas cov xov dub me ntsis, peb xav tau nws ob peb ntiv ntev dua Tam sim no koj tau npaj los ua lub hauv paus!

Kauj Ruam 8: Ntoo Tsob Ntoo

Nqa cov ntoo thaiv (lossis cov duab ncig) thiab laum lub qhov nyob hauv nruab nrab ntawm nws nrog me ntsis uas yog me ntsis me dua li txoj kab uas hla ntawm xaim/lub tsho khuam koj siv. Tam sim no, txiav lub block nyob rau hauv ib nrab nrog rab riam.

tam sim no, siv lub dremel thiab cov cuab yeej txiav, txiav tawm ib sab saum toj ntawm ib qho ntawm cov txiv laum huab xeeb lub thawv npog. Ua kom sov koj cov kua nplaum kub thiab kua nplaum ib qho ntawm cov ntoo mus rau txiv laum huab xeeb sab saum toj kom lub qhov kab nyob hauv qhov chaw nruab nrab ntawm lub hau (muaj lub txiv mis me me yog li nws yooj yim ua). Tom ntej no lo rau lwm daim mus rau qhov tseem tsis khov txiv laum huab xeeb lub hau hau. Tom qab ntawd siv tib lub laum me me uas koj tau siv rau ntoo thiab laum rau hauv cov txiv laum huab xeeb uas tsis huv los ntawm lub qhov uas koj ua hauv ntoo. Tam sim no, hauv feem ntau tsis muaj lub hau, siv cov ntaub ntawv (lossis dremel), ua 1/4 hauv los ntawm 1/4 txiav rau sab ntawm lub hau, qhov no yog rau USB cable. Tom ntej no, rub peb lub xov hlau (ib qho los ntawm LEDs ntsuab/xiav, ib qho los ntawm LEDs liab, thiab ib qho los ntawm cov LEDs dawb) hla lub qhov, thiab tom qab ntawd muab tsob ntoo ntoo hla lub qhov thiab. Nws yuav tsum haum zoo nkauj heev. Tam sim no, muab cov hlau xaim los ntawm ntsuab/xiav LEDs rau ib qho ntawm 178 ohm resistors (ib 390 thiab ib qho 330), xaim los ntawm cov liab LEDs mus rau 195 (ob 390's) ohm resistor, thiab xaim los ntawm cov dawb LED rau lwm 178 ohm resistor (ib qho 390 thiab ib qho 330). Npog txhua qhov kev sib txuas qhib (tshwj tsis yog qhov qhib kawg ntawm cov xaim dub) nrog cov kab xev hluav taws xob, koj tsis xav tau luv luv, thiab kub kua nplaum USB kab rau hauv qhov muab nws txog li ib nti hauv lub hau. Tam sim no, koj tuaj yeem sim thiab muab cov hlua txuas txuas dub txuas rau tsob ntoo, tab sis kuv qhia kom cia li hle nws ntev zoo nkauj thiab hu xov tooj kom haum cov hlau ntawm lub cev thiab cov ntoo hauv qab.
