Yog tias koj xav tso lub teeb nyob qhov twg uas tsis qiv nws tus kheej rau txuas rau hauv, qhov no tsuas yog qhov koj xav tau.

Kauj Ruam 1: Yuav Ua Li Cas Kuv Ua Yooj Yim, Tsis Muaj Teeb Meem-qhib Teeb

Nov yog qhov haujlwm yooj yim los tsim. Tsuas muaj 3 ntu - lub PC board, teeb, thiab roj teeb.

Kuv tso ib qho rau hauv qab ntawm tus ntaiv tsaus ntuj yog li kuv tsis tas yuav tig lub teeb lub taub hau thiab tso tawm. Nws khiav ntawm qhov zoo ib yam 9-volt (lossis 12-volt) roj teeb, yog li nws ua haujlwm nyob txhua qhov chaw.

Ib tus phooj ywg muab nws tso rau hauv qhov chaw pw ntawm nws lub tsheb thauj khoom. Lwm tus phooj ywg muab lawv lub qhov rooj kaw kom lub chav muaj teeb pom kev sai li sai tau thaum lawv taug kev. Nws tsis "kaw" thaum nruab hnub, tab sis tag nrho cov khoom raug nqi tsawg dua $ 3 ntxiv rau roj teeb thiab qee qhov pheej yig lossis tshuav LED ($ 1).

Kuv lub teeb yog LED me me, tab sis koj tuaj yeem hloov kho nws kom pom ntau npaum li koj xav tau tsuav nws ua haujlwm ntawm 9 lossis 12 volts. Koj tuaj yeem siv zog ntau dua cov khoom siv hluav taws xob los ntawm kev xa tawm, tab sis qhov ntawd dhau ntawm qhov kev qhia no.

Kuv lub roj teeb kav txog li ib xyoos. Yog tias koj ntxiv LED ntau, koj lub roj teeb lub neej yuav luv dua, pom tseeb. Kev tshaj tawm tau tshaj tawm kom tswj tau 5 amps (lossis 60 watts), uas yog ntau dua qhov loj txaus rau yuav luag txhua yam uas koj tab tom npaj. Kev xa rov qab yog cim "20 Amps" tab sis koj yuav ruam kom cia siab tias nws yuav nyob ntev ntawm qhov haujlwm ntawd.

Ib zaug qhib, nws nyob twj ywm li ntawm 15 vib nas this tom qab nws tsis hnov qhov txav mus los lawm. Kev hnov lus nyob deb li ntawm 2 feet deb.

Kauj Ruam 2: Sau Cov Khoom

Kuv yuav txhua yam ntawm eBay, tsis muaj dab tsi kim heev.

Tshawb nrhiav DC 12V 5A IR Pyroelectric Infrared PIR Motion Sensor Detector - cov nqi no qis dua $ 3

Xaiv ib co LEDs. Kuv muaj qee qhov seem ntawm lwm qhov haujlwm. Sib piv qhov hluav taws xob rau koj lub zog hluav taws xob (9 volts, 12 volts, thiab lwm yam) Ua eBay tshawb rau yam koj nyiam. Hauv kuv qhov xwm txheej, txij li thaum kuv tau teeb pom qhov chaw tsaus, lawv tsis tas yuav muaj zog heev. Kuv muaj ib txoj hlua nrog lub ntsaws ntawm qhov kawg.

Koj yuav xav tau qee qhov 9-volt roj teeb snaps. Lawv nyob 10 rau $ 1 ntawm eBay.

Koj yuav xav tau lub roj teeb 9-volt lossis lub zog zoo sib xws.

Kuv muab lub rooj tsavxwm thiab roj teeb tso rau hauv Altoids tin (nrog qee cov kab xev kaw rau hauv qab kom lub PC board tsis luv ntawm cov hlau).

Cov hlua LED tau tsim los tsim 3 xim ywj pheej ntawm lub teeb. Thaum tag nrho 3 tau qhib, nws tsuas yog lub teeb dawb xwb.

Kuv xaim qhov tsis zoo ntawm tag nrho peb qhov xim LED mus rau Cov Hlau Daj (uas tom qab ntawd txuas mus rau qhov tsis zoo thaiv thaum lub ntsuas pom pom txav mus). Qhov zoo ntawm ob sab ntawm LED mus rau kab liab.

Kauj Ruam 3: Muab tag nrho ua ke

Kuv tau siv tag nrho cov xov hlau (YouTube cov vis dis aus yuav qhia koj li cas) tab sis yog tias koj tsis yog qhov uas koj tuaj yeem tsuas yog ntsaws cov xov hlau ua ke thiab ntxiv qee qhov sib txuas ntawm cov xov hlau, lossis kab xev hluav taws xob, lossis txawm tias kab xev yog koj nyob nraum ntawm qhov peev nyiaj tsawg;-) lossis tsuas yog qee cov kua nplaum los tiv thaiv txhua yam thiab tuav nws ua ke. Tsis muaj leej twg yuav poob siab lossis hluav taws tawm ntawm qhov no (tshwj tsis yog koj sim siv Lithium roj teeb lossis qee yam).

Tej zaum koj yuav xav tau cov LED uas twb muaj xaim lossis txuas rau lawv yog tias koj tsis xav tau cov laug. Qhov txuas ntawm LED sawb Kuv tau qiv nws tus kheej rau "xaim qhwv" - cov cuab yeej tshwj xeeb me me siv nrog cov xaim zoo heev uas qhwv ib puag ncig me me.

Ib qho xaim liab yog Qhov Zoo +, Cov xov hlau dub tsis zoo -, Cov xim daj daj yog "hloov" xaim siv los qhib thiab kaw ib yam dab tsi. Koj yuav siv Cov xov hlau liab los txuas lub zog thiab lub teeb, Cov xov hlau dub txuas rau txhua qhov hauv av, thiab Cov xaim daj los hloov lub LED ("thauj khoom") qhib thiab kaw.

Koj yuav siv Cov Hluav Taws Xob daj los ua qhov hloov pauv, txuas nws mus rau qhov tsis zoo - sab ntawm LED (qhov tseeb, koj tab tom hloov hauv av/Sab tsis zoo ntawm lub nra rau thiab tawm. Qhov no Tsis yog txoj hauv kev siab -tsev AC thaiv tau siv, tab sis rau qis-voltage nws zoo). Qhov zoo + sab ntawm LED mus rau Cov xov hlau liab.

Yog tias koj xav kom nws ua haujlwm rov qab (thauj khoom ib txwm nyob, tom qab ntawv kaw thaum lub zog pom) tsuas yog hloov qhov sib txawv ntawm cov hlau daj. (Cov xaim daj mus rau cov hlau lead zoo LED, Cov xaim dub mus rau qhov tsis zoo ntawm LED.) Koj yuav txawm xav txog qhov haujlwm uas muaj qee yam ib txwm nyob, tom qab ntawv tua thaum txav mus. Hauv lwm lo lus, muaj ib qho "Qhib Qhib Hloov" lub xeev (tua tawm) thiab "Ib txwm kaw qhov hloov pauv" lub xeev (qhib rau) rau kev hloov pauv tau ua los ntawm kev xa tawm. Cov xeev no tau thim rov qab thaum lub ntsuas pom pom qhov txav mus, nyob twj ywm rov qab kom ntev li ntev tau muaj cov lus tsa suab, tom qab ntawd tos lwm 15 vib nas this, tom qab ntawd rov qab mus rau nws lub xeev qub. Cov txheej txheem, koj tuaj yeem siv lub voj voog no kom muaj qee yam qhib rau txhua lub sijhawm, tom qab ntawd pom cov lus tsa suab thiab tua cov khoom uas tau qhib, thiab qhib lub zog thib ob thaum thawj zaug raug kaw. Ib pliag tom qab, lawv yuav rov qab mus rau lawv lub xeev qub.

Txog qhov ntawd, koj yuav txiav txim siab ntxiv AC fais fab mov, vim qee yam yuav ib txwm siv lub zog.

Nco ntsoov lub ntsuas cua yuav ua haujlwm ntawm 9 lossis 12 volts, koj qhov txwv tsuas yog LED qhov tshwj xeeb qhov tshwj xeeb. Muaj tons ntawm 12-volt LED daws teeb meem npaj rau tsheb. Lub voj voog no tseem tuaj yeem siv txuas rau lub tsheb nrog kev sib txuas kom raug thiab saib xyuas. Yuav ua li cas txog lub teeb sab nraud uas tig thaum koj lub taub hau (lub ntsuas cua) nyob hauv 2 ko taw ntawm ib yam dab tsi?

Tej zaum koj yuav tsis tuaj yeem tshuab ib yam dab tsi yog tias koj ua qee yam tsis raug. Yog tias nws tsis ua haujlwm thaum xub thawj, tsuas yog so thiab saib nws dua tom qab. Pib tawm yooj yim thiab ntxiv LED ntxiv tom qab.

Yog tias koj xav txwv lossis nqaim qhov chaw hnov, koj tuaj yeem tso daim kab xev me me hla lub ntsuas cua. Piv txwv li, peb muaj lub thoob khib nyiab tuaj yeem tso rau hauv chav ua noj. Tab sis nws nyob hauv thaj chaw nruj, thiab peb tsis xav kom lub hauv paus qhib rau txhua lub sijhawm ib tus neeg taug kev los. Ib daim kab xev dub me me ua rau nws nkag siab qhov chaw.

Kauj Ruam 4: Cov Lus Cim Kawg

Qhov kev tswj hwm no tuaj yeem siv rau tsuas yog ib qho me me-ish load. LEDs thiab roj teeb yog DC, tab sis kev xa tawm tsuas yog ib qho SPDT Hloov (ib leeg-ncej, muab ob npaug rau) hloov, yog li nws ua haujlwm nrog AC cov cuab yeej, ib yam nkaus.

Yog tias koj xav kom lub nra nyob qee qhov deb ntawm lub ntsuas cua, koj yuav zoo dua los txuas cov kab txuas uas muaj zog (liab thiab dub) ntau dua li lub xov hlau thaiv. Kev txuas cov xov hluav taws xob ntawm lub ntsuas hluav taws xob yuav ua rau muaj kev pheej hmoo ntawm kev cuam tshuam nrog cov kab hluav taws xob txuas mus rau "kav hlau txais xov" ntev uas tuaj yeem khaws lwm cov cim, ua rau muaj teeb meem nrog cov txiaj ntsig zoo ib yam. Cov xov hluav taws xob tsis tshua muaj peev xwm khaws cov cim tsis raug thiab teb.

Muaj ntau qhov nthuav dav hauv Circuit Court ntawm eBay ntau dua li koj tuaj yeem suav tau. Lawv feem ntau yog siv tau yooj yim; ob peb zoo li npaj rau cov khoom siv loj dua thiab tuaj yeem ua rau me ntsis clumsy los txuas rau lossis nrhiav cov duab kos thiab cov lus qhia tshwj xeeb. Tab sis tus nqi tsis tuaj yeem tuav.

Tsis txhob hnov qab tias feem ntau ntawm cov khoom sim uas pheej yig no tau xa los ntawm nkoj los ntawm Asia. Cia siab tias yuav muaj 6 lub lis piam khoom xa tuaj.
