2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Hauv cov lus qhia no kuv qhia koj yuav ua li cas ua koj tus kheej lub teeb nyem LED uas tuaj yeem rov tau yooj yim los ntawm kev ntsaws nws rau hauv USB chaw nres nkoj ntawm koj lub computer. Kuv paub tias koj tuaj yeem pom qee yam zoo sib xws los ntawm lub khw, tab sis txhua qhov uas kuv pom muaj tsuas yog ob peb LEDs yog li kuv tau ua kuv tus kheej nrog yim LEDs.

Kauj Ruam 1: Cov Cuab Yeej thiab Qhov Yuav Tsum Tau

Cov cuab yeej suav nrog: 1 rab riam nyiam 2 tes tuav 3 lub lauj kaub hlau 4 tus ntsia hlau tsav 5 txiab 6 hlau txiav 7 pliers 8 tus xaum 9 laum thiab laum cov khoom me me suav nrog 1 Stripboard lossis Circuit board 2 8x LEDs 3. qhib/tua 4 3x ni-cd khawm cells 5 1x 36 ohm lossis 8x 120 ohm resistor 6 yas thiab txhuas ntawv 7 hluav taws xob wirier thiab hlau wirier 8 kab xev 9 solder 10 USB flash drive (Kuv pom zoo ib qho uas tsis muaj lub tshuab zawv zawg)

Kauj Ruam 2: Kev faib tawm

Cov kauj ruam no yooj yim heev. Tsuas yog siv lub taub hau ntswj taub hau kom qhib lub flash drive. Ib qho kuv pib nrog tau tawg yog li kuv txiav lub Circuit Court bored tawm kom txuag tau qee qhov chaw thiab nthuav tawm cov kab zoo thiab tsis zoo, tom qab ntawd kuv siv lub ntsuas hluav taws xob ntsuas lub polarity ntawm usb Kuv qhia tias koj siv tus cwj mem los cim zoo thiab tsis zoo, yog tias koj tau ua li ntawd ces koj tau ua tiav cov theem no. Yog tias koj ua qhov no nrog ua haujlwm flash drive thiab koj xav khaws lub cim xeeb ua haujlwm, tom qab ntawd koj yuav tsum ntxiv ib qho ntxiv Circuit. Pib los ntawm kev xaim xov hlau rau hauv av lossis xaim tsis zoo ntawm lub flash drive tom qab txiav cov hlau zoo thiab muab peb qhov taw tes toggle hloov (raws li pom ntawm daim duab kawg) nyob rau hauv qhov chaw ntawm qhov ua tau zoo ntawm usb yuav txuas mus rau nruab nrab taw tes ntawm qhov hloov pauv thiab ob sab nyob deb ntawm qhov hloov pauv yuav txuas mus rau qhov kawg ntawm lub flash drive thiab cov lus pom zoo ntawm Circuit Court ntawm qib plaub. Thaum kawg muab qee daim kab xev rau ntawm lub nyem kom nws tsis luv.

Kauj Ruam 3: Roj Teeb Ua Ke

Qhov nyuaj tshaj plaws ntawm txoj haujlwm no yog txhawm rau nrhiav qee lub npib tsib xee-cadmium roj teeb ntawm tes, Kuv pom qee qhov los ntawm kev qhib qhib qhov tsis tshua muaj 4.8 v roj teeb uas kuv tau txais los ntawm lub khw hluav taws xob hauv ib cheeb tsam. iI koj tsis pom lub roj teeb no zoo li yuav yog koj li teeb meem, koj tuaj yeem tau txais qee lub roj teeb me-ni los ntawm kev qhib 9v ni-cd roj teeb dab yog qhov ua haujlwm 8.4v uas tuaj yeem pom ntawm https://www.cheapbatteries.com /nicd.htm Ob txoj hauv kev ib zaug koj tau pom qee lub roj teeb me me ni-cd koj yuav xav tau txuas qee cov xov hlau rau lub roj teeb thiab kaw peb lub roj teeb ua ke kom tau txais pob roj teeb 3.6v, qhov no yuav tsis rov qab yog tias koj muaj plaub lub roj teeb koj yuav pom tias lawv yuav tsis them vim qhov hluav taws xob tau sib faib ntawm cov cell thiab koj xav tau yam tsawg 1.6v mus los ntawm cov roj teeb dua li 1.7v Cov theem no tam sim no tiav.

Kauj Ruam 4: Txuas thiab Vaj Tsev

Hauv cov kauj ruam no thawj qhov uas yuav tsum tau ua yog xyuas yog tias txhua qhov ntu haum hauv nyem, feem ntau lawv yuav tsis siv rab riam hobby kom tshem qee cov yas thiab ua lub qhov rau qhov qhib/tawm hloov thiab xaiv tau hloov yog tias koj muaj lub cim xeeb Circuit. Koj thaum koj tau ua qee chav koj xav xav pib ua qee qhov kev sib txuas raws li cov txheej txheem. Pib los ntawm kev txuas cov txiaj ntsig zoo mus rau qhov kawg ntawm lub roj teeb thiab ib qho kawg ntawm qhov qhib/tua hloov, tom qab ntawd txuas qhov tsis zoo rau qhov tsis zoo kawg ntawm lub roj teeb thiab rau tus tiv thaiv lossis tiv thaiv. Tom qab ntawd txuas lwm qhov kawg ntawm kev qhib/tawm mus rau txhua qhov zoo ntawm LEDS. Nruab nrab ntawm txhua qhov tsis zoo LED xaus, lub roj teeb thiab cov txiaj ntsig tsis zoo, koj tuaj yeem muaj ib qho 36 ohm resistor lossis 120 ohm resistor ntawm txhua qhov kawg ntawm lLEDs Kuv pom zoo tias koj ua rau kev tiv thaiv siab dua ces nws yuav tsum yog thaum cov roj teeb lossis koj lub khoos phis tawj muaj qhov tso tawm siab dua 5v, Ob txoj hauv kev qhia tus tiv thaiv yuav ua haujlwm tab sis nws zoo dua yog tias muaj lub zog tiv thaiv ntawm txhua LED thaum qee qhov ntawm lawv tawg thiab qhov seem yuav muaj ntau dhau thiab lawv yuav hlawv tawm. Thaum koj muaj qhov hloov pauv, roj teeb thiab ob lub xov hlau tawm mus, cov kauj ruam no tiav tab sis feem ntau cov roj teeb yuav tuab heev yog li siv qee cov yas tawv los ua lub thawv kom tsa lub hau me ntsis.

Kauj Ruam 5: Led Circuit

Hauv cov kauj ruam no koj yuav txiav ob daim kab txaij thiab cov tub rog LEDs rau nws Nco ntsoov kom muaj cov LEDs sib luag thiab kom muaj txhua tus coj hauv tib txoj kev. Thaum koj muaj cov LEDs muag hauv qhov chaw, txiav cov hlau lead. Rov ua dua qhov no thiab qhov no tiav. Yog tias koj muaj 8 tus tiv thaiv ces koj yuav tsum muaj tus tiv thaiv ntawm LED thiab txuas txuas hlau loj.

Kauj Ruam 6: Ua tiav

Qhov no yog theem kawg, pib los ntawm kev txheeb xyuas qhov sib txawv ntawm ob lub xov hlau ua ntej tom qab ntawd muag cov xov hlau zoo mus rau qhov kawg ntawm LED kev sib txuas tom qab ntawd txuas qhov tsis zoo kawg rau cov tiv thaiv. Thaum qhov ntawd tau ua tiav, muab ob lub xov hlau txuas rau ob sab ntawm LEDs. Tom qab ntawd lo lub hau rov qab thiab ua lub pob khawm rau qhov thib ob Circuit Court LED thiab siv qee cov kua nplaum super kom ruaj ntseg nws. Tam sim no muab cov xov hlau txuas rau ob txheej ntawm LEDs thiab ntxiv ob lub hlau nplaum me me kom lub pob khawm nyob hauv qhov chaw. Feem ntau cov roj teeb ni-cd xav tau them ntev yog tias lawv siv sijhawm ntev nrog tsis tau them, yog li yooj yim ntsaws nws hauv koj lub computer rau kaum yim teev tom qab ntawd nws tau npaj siv, txhua lub roj teeb ntawm tes yuav muaj 1.2 v sib npaug 3 uas yuav sib npaug 3.6V thiab kom them lawv koj yuav tsum muab 1.7v, sib npaug los ntawm cov xov tooj ntawm tes yog li koj yuav tsum tau txais 5.1v uas yog qhov tso tawm ntawm koj lub computer. Nrog 5.1v lub roj teeb yuav tsum tau them hauv 2 teev nrog 5v nws yuav tsum siv sijhawm ntev me ntsis. Thaum nws tau them tag nrho LED yuav siv 80 mA lossis 0.08 A thiab lub roj teeb uas kuv tau ntsia nrog tau ntsuas txog 60 mA uas txhais tau tias nws tuaj yeem muab tau 60 mA, yog li faib 60 los ntawm 80 thiab koj yuav tau txais 0.75 uas yog 0.75 / 1hour. Yog li koj tuaj yeem tig 0.75 ntawm ib teev los sib npaug 45 feeb uas yog lub roj teeb lub neej ua ntej nws xav tau kev them nyiaj rov qab. Nco ntsoov tias qhov no yuav yog sib txawv nyob ntawm cov roj teeb thiab LEDs koj siv.some ntawm cov qauv A = amps, B = roj teeb, C = roj teeb ntawm tes, H = teev, L = coj, LA = LED amps, R = tsis kam hauv ohms, V = volts, W = watt, Wi = amp rho tawm, x = sib npaug, X = tus lej tsis paub, W = (VxA) tus naj npawb ntawm ohms xav tau thaum nyob ua ke R = (v1-v2)/(LAxL) v1 = lub zog hluav taws xob v2 = LED voltage charger voltage rau ni-cd roj teeb V = (1.7xC) roj teeb lub neej (BAH/WI = X/1H) hloov pauv kaum zauv ntawm ib teev (X) rau feeb (Xx60) = tus lej

Kauj Ruam 7: Sib Piv Cov Teeb Pom Kev

Kuv tau sau ntau lub teeb pom kev nqa los sib piv rau kuv lub teeb USB tshiab, lub teeb pom kev uas kuv xaiv los sib piv yog: tswm ciab nrog lub teeb pom kev zoo, lub teeb 6v lub teeb nyem, lub teeb nyem tseem ceeb teeb nrog ib qho LED, thiab lub teeb nyem. nrog 16 lub siab siv LEDs uas yuav muaj lub zog zoo ib yam li Maglite loj. Thawj daim duab qhia pom lub teeb pom kev los ntawm dimmest ntawm sab laug mus rau qhov ci tshaj plaws ntawm sab xis. Cov duab 5 tom ntej no yog teeb teeb nyob rau hauv tib qho kev txiav txim, txhua ntawm lawv yog 10 ko taw los ntawm lub koob yees duab lens. Sib piv lawv los ntawm qhov loj ntawm sab hauv feem ntau. Txawm hais tias lub teeb nyem USB tshiab nyob hauv qhov chaw thib ob ntawm lub teeb nyem kuv tau sim, txiav txim siab tias nws yuav nyob ntev li 45 feeb ua ntej yuav tsum tau them nyiaj 2 teev thiab nws tuaj yeem haum rau sab hauv lub teeb ci tshaj plaws (nyiaj ntawm sab xis) nrog cov roj teeb tshem tawm.
