Christmas teeb pom kev zoo yog qhov ci thiab hlawv tawm ntawm qhov nce zuj zus. Qhov no tau nrawm txaus uas kuv cov phooj ywg nyob hauv chav thiab kuv tau txais blisters los ntawm rub lawv. Kuv muaj cov teeb ntawd ntau dua ob xyoos thiab kuv tsis tau mus yam tsis muaj teeb pom kev ib puag ncig. Kuv xav tias LEDs yog txoj kev mus.

Txhua tus qauv siv los ntawm 12V thiab yog qhov yooj yim hauv lub tswv yim. Tus naj npawb ntawm LEDs koj xav tau rau ib tus qauv nyob ntawm qhov hluav taws xob ntawm LED. Feem ntau koj tuaj yeem tau txais 3 xim av lossis zaub ntsuab (3.4V txhua) ntawm tus qauv lossis 5 liab (2.4V txhua) ntawm tus qauv. Muaj ntau tus lej ntawm cov qauv tuaj yeem raug tshem tawm ntawm ib qho khoom siv. Tus lej ntau tshaj plaws ntawm cov qauv uas tuaj yeem siv tau los ntawm cov khoom siv ib leeg tuaj yeem ua tau yog nws qhov amperage faib los ntawm tam sim no ib qho LED rub tawm. Hauv kuv qhov xwm txheej, Kuv tau siv 12V 5A lub zog xa khoom los ntawm Digium thiab 20mA LEDs, yog li ntawd muab rau kuv 250 (5/0.02) cov qauv rau ib qho khoom siv. Qhov ntawd yog qhov pom kev tag nrho! Qhov chaw rau txhua tus qauv: Ib daim ntawv ntawm 3 daim LEDs xiav (3.4V) 100 ohm resistor 2 me me neodymium hlau nplaum 2 ferromagnetic thumbtacks Lwm cov ntaub ntawv: Soldering Iron Solder Hot Glue Gun Glue Sticks Speaker Wire A 12V Power Supply

Kauj Ruam 1: Cov Ntaub Ntawv thiab Lub Koom Haum

Koj thawj txoj haujlwm yog khaws koj cov ntaub ntawv thiab nrhiav cov qauv teeb tsa uas haum rau koj. Rau txhua tus qauv, koj yuav xav tau qee qhov perfboard (cov khoom pheej yig yog tias ua tau), 100 ohm resistor, peb 3.4V xiav LEDs, ob 1/8 "x1/8" neodymium hlau nplaum, thiab ob lub suab paj nruag ferromagnetic. Txog cov khoom siv dav dav, koj yuav xav tau 12V lub zog xa khoom, qee qhov hais lus pheej yig xaim, hlau txuas, qee cov laug (txhuas/tin), rab phom kub kub, thiab qee cov kua nplaum lo nrog nws. Tus tuav tes pcb thib peb yog qhov muaj txiaj ntsig, tab sis tsis xav tau. Raws li rau lub koom haum ntawm lub rooj sib tham, nws yog qhov tseeb rau koj, tab sis kuv tau xaiv ntev thiab yuag yog li kuv cov qauv yuav muaj qhov zoo sib xws rau cov xaim nws tus kheej thiab tsis muaj kev cuam tshuam tsawg.

Thaum koj tau txiav txim siab qhov LEDs mus qhov twg, nco ntsoov tias lawv nyob hauv qhov kev qhia raug. Cov hlau lead ntev dua yog qhov zoo thiab ploj mus ntawm tus tiv thaiv. Tus tiv thaiv yuav yog qhov txuas rau hauv av rau tus qauv. Kuv tau tso qhov sib txawv nruab nrab ntawm cov perfboard thiab cov LEDs kom kuv tuaj yeem khoov lawv thiab faib lub teeb kom zoo dua. Khoov cov coj uas yuav txuas mus rau ib leeg kom lawv nteg sib luag thiab yuav luag kov. Qhov kawg ntawm qhov no tau qhia hauv qib tom ntej.

Kauj Ruam 2: Soldering thiab Coils

Tam sim no koj muaj koj li LED thiab cov neeg tawm tsam ua rau khoov mus rau txoj haujlwm kom raug, koj yuav tsum tau muab lawv txuas ua ke thiab txiav tawm qhov feem ntau ntawm txhua qhov txhuas. Saib xyuas TSIS TXHOB txiav cov txheej txheem sab nraud raws li koj xav tau lawv hauv ib feeb. Sim siv qhov tsawg kawg nkaus ntawm cov kab laug sab uas tsim nyog.

Nqa ib qho ntawm cov hlau nplaum thiab khoov txheej sab nraud ib puag ncig nws, tsim lub caij nplooj ntoo hlav lossis cov qauv zoo li cov qauv. Qhov no yuav pab tuav cov hlau nplaum nyob hauv qhov chaw thiab tswj kev coj ua. Thaum koj muaj ob qho kawg coiled kom raug, ntxig cov hlau nplaum thiab xyuas kom lawv tseem haum. Nws yog qhov yooj yim yooj yim los cuam tshuam qhov no, yog li koj yuav tsum tau xyaum nws me ntsis. Koj yuav tsum tau ceev faj heev ntawm cov kauj ruam no lossis koj yuav rhuav tshem cov hlau nplaum. Txawm tias lub sijhawm luv luv raug rau qhov kub siab tuaj yeem ua rau cov hlau nplaum poob nws cov hlau nplaum. Txij li cov hlau lead tiv thaiv tsis yog sib nqus, Kuv xav qhia siv me ntsis ntawm cov laug kom txuas nws mus rau cov hlau nplaum. Koj xav kom qhov no ua kom sov sib koom ua ke, tsis yog qhov sib txuas ua kom sov.

Kauj Ruam 3: Kub Nplaum thiab Thumbtacks

Txij li txhua yam tau muag tam sim no, koj tsuas yog muaj me ntsis ntxiv mus kom txog thaum koj cov qauv LED ua haujlwm tau. Nqa rab phom kub kub thiab nplaum cov hlau nplaum rau ntawm lawv ob sab. Tsis tas yuav txhawj ntau txog kev tua cov hlau nplaum ntawm no txij li cov kua nplaum phom tsis hloov pauv kom ze li cua sov rau lawv li cov hlau txuas. Tos kom cov kua nplaum ua tawv ua ntej sim ua ntu tom ntej.

Thaum cov kua nplaum tau khov lawm, coj tus qauv, teeb nws nyob ib sab ntawm tus hais lus xaim, thiab kos lub xaim uas qhov chaw nruab nrab ntawm txhua tus hlau nplaum yuav los nrog nws. Nov yog qhov uas koj yuav tsum tau ntxig tus thumbtacks rau ntawm xaim. Xyuas kom lawv txhaws tus neeg xyuas pib sab hauv xaim. Qhov no tsis yooj yim rau mess, tab sis yog tias koj tsis meej pem, koj tuaj yeem tshawb xyuas nrog lub ntsuas cua kom ntseeg tau tias muaj kev coj ua. Nco ntsoov tias txhua khub ntawm tacks tsis nkag mus rau tib tus neeg xyuas pib. Nov yog yuav ua li cas cov modules tau siv, thiab yog tias ob qho tib si nkag mus rau tib tus neeg xyuas pib, tus qauv ntawd yuav tsis ua haujlwm. Thaum koj muaj qhov sib nrug ntawm txoj cai, koj tuaj yeem siv tus ntiv tes xoo koj tsuas yog muab tso rau hauv tus qauv rau seem ntawm cov hlau thiab vim tias lawv muaj qhov zoo li qhov loj, muaj ntau chav rau yuam kev. Lwm qhov ntxiv yog tias tsis tas yuav muaj cov ntsia hlau hauv phab ntsa rau nws. Tsuas yog rauj cov lus qhia ntawm tacks rau hauv phab ntsa! Tam sim no koj muaj koj tus ntiv tes xoo hauv koj lub xaim, txuas lub 12V khoom thiab txuas tus qauv rau ib khub. Yog tias nws tsis ua haujlwm, sim tig lub module ib ncig. Rov qab polarity yuav tsis ua mob rau nws. Yog tias nws tseem tsis ua haujlwm, xyuas kom koj kev sib txuas tau zoo ntawm LEDs thiab tshwj xeeb, ntawm tus tiv thaiv thiab nws cov hlau nplaum. Qhia yog qhov ze ntawm ib qho qauv ua haujlwm thiab kuv txoj kev hauv tsev ze rau nruab hnub nrig. Yog tias koj xav ua tus qauv liab hloov xim ntsuab lossis xiav, hloov peb lub xiav lossis ntsuab LEDs rau 5 tus liab thiab 100 ohm resistor rau 1 ohm resistor.

Kauj Ruam 4: Cov Khoom Kawg

Nov yog kev pom hmo ntuj ntawm qhov khoom kawg ntawm txoj haujlwm no. Qhov no, ntxiv rau chav ua noj ib nrab ntawm lub teeb pom kev zoo, tsuas yog rub 1.26A ntawm qhov tam sim no. Qhov no txhais tau tias kuv lub zog siv tsuas yog 1/4 lub peev xwm! Kuv tuaj yeem yooj yim dua tus lej ntawm cov qauv thiab npog qhov seem ntawm kuv chav tsev, tsis hais txog qhov ua tau ntawm cov dej khov nab kuab style. Qhov zoo nkauj tiag tiag ntawm qhov no los rau hauv kev ua si yog tias ib qho qauv puas tau hlawv tawm. Tsis muaj txoj hauv kev nws tuaj yeem cuam tshuam rau cov qauv ntxiv thiab koj tsuas tuaj yeem rub nws tawm ntawm cov xaim los kho nws. Kev kub hnyiab tshwm sim ntawm tus nqi sib txawv heev, qhov twg Christmas teeb tau hlawv tawm ntawm qhov nthuav tawm. Kuv tseem tsis tau hlawv ib yam rau kuv.

Kuj txaus txaus, txoj haujlwm no tsuas yog siv li ntawm 12-15 tus txiv neej teev kom ua tiav suav nrog txhua tus qauv LED thiab teeb tsa tus hais lus xaim nrog tus ntiv tes xoo. Nrog kev pab los ntawm kuv cov phooj ywg, peb tau txais txhua txoj hauv kev coiled, cov hlau nplaum nplaum, thiab xaim xaim hauv ob peb teev. Tus nqi tau siab me ntsis, tab sis kuv xav hais tias $ 100 yog tus nqi zoo rau teeb pom kev zoo koj yuav tsis tas yuav hloov pauv rau kaum xyoo los yog li ntawd.
