Xav tau qee lub teeb ci kom ua rau koj Halloween Haunt tiav? Tsis txaus siab los ntawm lwm cov kev daws teeb meem? Zoo li yaj cov laug thiab rov ua lub hom phiaj hluav taws xob? Tom qab ntawv Cov Lus Qhia no yog nyob rau ntawm koj txoj kab lus. Qhov chaw qhia no tsuas yog cov khoom siv hluav taws xob tiag tiag. Kev koom ua ke rau hauv teeb, taub taub, tswm ciab, thiab lwm yam yog ib qho kev tawm dag zog rau tus nyeem ntawv. Tus kheej, Kuv tab tom siv lub voj voos no hauv ob lub teeb, ib lub taub yas yas uas tuaj pwm thiab rau txoj hlua taub dag. Cov lus qhia no yuav cuam tshuam nrog qhov kuv hu ua hom 1 li cas - thiaj li hu vim tias cov no yog thawj hom uas kuv pom. Hom 1 LED pov ntawv xaiv tsa muaj lub rooj sib tham me me nyob hauv lawv nrog lub chip-on-board (COB) Circuit thiab LED. Hom 2 LED pov ntawv xaiv tsa muaj cov kab hluav taws xob teeb tsa hauv LED nws tus kheej, zoo ib yam li tus qauv teeb nyem LED. Kuv tseem tsis tau txiav txim siab qhov tsim nyog siv tau rau hom no. Rau qhov kev qhia no, koj yuav xav tau hom 1 COB LED pov npav. Hmoov tsis kuv xav tias tsuas yog txoj hauv kev koj tuaj yeem txiav txim siab tias koj muaj dab tsi yog qhib lawv. Nws muaj peev xwm tua koj tau yog tias koj tsis quav ntsej. Txhua lub cuab yeej siv lub voj voog no yuav tsum tau nyob hauv lub thawv ntim khoom (piv txwv li yas). Qhov no tsis pom zoo ua thaum pib ua haujlwm hluav taws xob. Daim ntawv tshaj tawm tsis lees paub lub luag haujlwm rau kev puas tsuaj, raug mob lossis tuag vim yog tsim los lossis siv lub voj voog no. Hey, peb txhua tus paub txhua yam kev lom zem tiag tiag tuaj yeem tua koj;-) Lwm qhov ntawv: Cov lus qhia no yog me ntsis ntawm pob txha (hav, nws YOG Xus). Tus sau cia siab tias ib tus neeg paub txaus los tsim qhov no tuaj yeem txiav txim siab yuav ua li cas muab nws tso ua ke ntawm lwm yam uas tsis yog lub khob cij.

Kauj Ruam 1: Daim Ntawv Teev Npe

Tau kawg koj yuav xav tau qee qhov:- 1 lub tswm ciab LED-1 txuas txuas txuas ntxiv (txhawm rau muab lub zog rau hluav taws xob)- 1 lub teeb thiab lub qhov (socket) uas koj xav tau "flicker"- 1 tag nrho cov yoj choj choj rectifier -or-- 4 200v lossis zoo dua rectifier diodes los tsim choj rectifier- 1 470nF 250v capacitor lossis zoo sib xws/zoo dua- 1 3.1v zener diode- 1 470uF 10v electrolytic capacitor lossis zoo ib yam/zoo dua- 1 220 ohm resistor-1 MOC3023 opto-isolator/triac tsav-1 BT134 (lossis simiar) triacI tau khaws 470nF 250v cov khoom siv hluav taws xob thiab lub zog txuas hluav taws xob tag nrho los ntawm CRT saib. Kuv kuj tseem tau siv lub triple tap txuas nrog "thauj khoom" rau hauv Circuit Court yog li kuv tuaj yeem ntsaws rau hauv txoj hlua ntawm cov teeb tshiab. Nco tseg: Yog tias koj sim tsav lub nra hnyav nrog lub voj voog no, lub triac yuav sov dua thiab xav tau lub rhaub dej kub.

Kauj ruam 2: Schematic

Ob peb qhov kev ceeb toom: Ib zaug ntxiv, lub voj voog no tau siv los ntawm 120V A/C lub tsev tam sim no. Koj tuaj yeem raug mob lossis raug tua yog tias koj ua tsis zoo lossis ua yuam kev. Compom C1, B1, D1 thiab C2 ua lub tshuab hluav taws xob hloov pauv tsawg-tsawg qhov hluav taws xob muab rau lub nti ntawm lub tshuab hluav taws xob tshem tawm ntawm LED votive. Kuv tsis ua txuj ua kom nkag siab ntu no tag, tab sis kuv qhov kev nkag siab dav dav yog: C1 txwv qhov tam sim no los ntawm 120V lub tsev khoom siv. B1 yog lub tshuab hluav taws xob txuas hluav taws xob tag nrho, ib qho khoom siv lossis tsim los ntawm 4 lub kho qhov hluav taws xob diodes. Cov zis yog DC. D1 yog 3.1V zener diode uas txwv qhov hluav taws xob. Xav tau qhov hluav taws xob siab dua, peb tus nqi sib txawv zener diode. C2 yog polarized electrolytic capacitor thiab ua rau lub ripple du los ntawm DC. Qhov tshwm sim DC yog "zoo txaus" rau COB. The MOC3023 opto-isolator triac tsav tsheb muaj IR sab hauv LED. Cov LED no siv qhov chaw ntawm LED thaum chiv thawj los ntawm COB. Thaum qhov hluav taws xob tso tawm los ntawm COB siab txaus, IR LED hauv MOC3023 tig rau qhov uas ua rau "IR rhiab diac" (kuv lub ntsiab lus) uas tig rau triac thiab muab lub zog rau lub nra - uas tuaj yeem yog lub teeb pom kev zoo ib yam li hauv lub teeb. Tsis txhob sim tsav lub teeb roj fluorescent compact, lub cev muaj zog, kab zappers lossis lwm yam.

Kauj Ruam 3: Sau COB Los ntawm LED Votive

Qhib qhib LED votive li cas koj nyiam. Feem ntau hauv qab yuav ntsaws tawm/tawm. Vam tias koj yuav pom qee yam zoo ib yam li daim duab hauv qab no. Lub rooj tsav xwm hauv Circuit nrog LED yog qhov koj xav tau. Nco ntsoov tag nrho cov polarities. Unsolder lub LED. Cov laug hauv cov pins ua los ntawm cov khoom qub coj yog tias koj xav tau. Qhov no ua rau nws yooj yim dua rau ntawm lub khob cij lossis cov ntawv ua haujlwm. Yog tias koj tsis pom lub rooj sib tham zoo li no, tab sis tsuas yog LED txuas nrog lub roj teeb thiab hloov, ces koj muaj Hom 2 LED votive. Thov txim tab sis koj nyob ntawm koj tus kheej lossis tos thiab saib yog tias kuv xam tawm qhov muaj txiaj ntsig hauv lub sijhawm rau koj cov kev xav tau.

Kauj Ruam 4: Breadboarded Circuit

Nov yog qhov Circuit Court ntawm daim ntawv qhia zaub mov. Xa mus rau daim duab kom paub ntau ntxiv.

Kauj Ruam 5: Ua

Nov yog daim vis dis aus ntawm kev ua haujlwm hauv Circuit. Koj yuav zaum pom tias lub teeb ci ntsa iab tsis flicker li 'huv' raws li LED. Xws li yog txoj cai ntawm physics. Cov teeb hluav taws xob ua haujlwm los ntawm cua sov cov ntsiab lus rau qhov kub kom nws tso lub teeb tawm (qhov no kuj yog vim li cas lawv thiaj nkim pov tseg). Lub voj voog txias txias yuav siv sijhawm me ntsis yog li lub teeb pom kev sib txawv yooj yim dua. Nws puas ntseeg ntau dua li LED? Tsis tuaj yeem hais - nws zoo txaus rau kuv lub hom phiaj.

Kauj Ruam 6: Koj Tig

OK, tam sim no koj tau txais qhov yooj yim Circuit Court. Nws nyob ntawm koj kom xa nws mus rau hauv rooj plaub muaj kev nyab xeeb thiab muab tso rau siv. Kuv tau siv nws hauv teeb thiab taub. Kuv twb tau siv ib qho ntawm cov kais peb zaug uas kuv txiav tawm ntawm txoj hlua txuas kom tuaj yeem siv hluav taws xob kom yooj yim tsav txoj hlua ntawm lub teeb tshiab. Nco ntsoov yog tias koj ntsaws lub Circuit ntau dhau, koj yuav tsum tau rhaub dej Muaj kev lom zem thiab muaj tswv yim!

Kauj Ruam 7: Cov ntawv ntxiv

Kuv nyeem qee qhov uas tsawg kawg qee qhov ntawm LED votive circuits siv cov suab paj nruag ntau dhau los ntawm kev lag luam daim npav tos txais. Kuv muaj tus hais lus me me piezo, yog li kuv tau txuas cov hlau lead rau hauv qhov tso tawm ntawm COB/cov tswv yim ntawm opto-isolator. Tseeb txaus, COB tau ua si Fur Elise. Ua tib zoo mloog cov vis dis aus thiab koj tuaj yeem hnov lub suab nkauj. Kuv muaj ob peb lwm cov ntawv pov npav LED ncaws ncig yog li kuv tau txheeb xyuas lawv. Ib tus ua si "Zoo Siab Hnub Yug" thiab yog qhov kev xaiv tsis zoo rau qhov kev sib tw no. Lwm qhov tsis tau ntaus nkauj, tab sis ua "duh duh duh" suab hauv tus qauv. Qhov ntawd ua haujlwm tau zoo hauv kab lus no ib yam nkaus. Nws tuaj yeem hloov kho qee qhov Circuit kom muab qhov txiaj ntsig zoo dua rau koj. Ntxiv cov neeg tawm tsam thiab/lossis cov khoom siv hluav taws xob rau qhov tso tawm ntawm COB/cov tswv yim ntawm opto-isolator tuaj yeem cuam tshuam cov txiaj ntsig. Nws kuj tseem tuaj yeem cuam tshuam qhov txiaj ntsig los ntawm kev hloov tus nqi ntawm 220 ohm resistor ntawm 'tso tawm' sab ntawm opto-isolator. Yog tias koj pom qhov ua tau zoo tshwj xeeb, thov qhia rau txhua tus paub. Koj tseem tuaj yeem siv SCR qhov chaw ntawm triac. Qhov no yuav txo hwj chim rau lub nra los ntawm 50% vim nws yog ib nrab-nthwv dej ntaus ntawv. Koj yuav zaum yuav tau hloov tus coj/tus pin nyob ib puag ncig vim nws tsis zoo li SCR yuav muaj tus pin teeb tsa tib yam li triac. Muaj kev lom zem thiab nyab xeeb. Ib zaug ntxiv, lub voj voog no muaj peev xwm ua rau tuag taus!
