joule tub sab (aka thaiv cov oscillator) yog hluav taws xob hluav taws xob uas tso cai rau koj siv cov roj teeb ib txwm xav tias tuag. Roj teeb feem ntau suav tias yog "tuag" thaum nws tsis tuaj yeem siv lub cuab yeej tshwj xeeb. Tab sis dab tsi tshwm sim tiag tiag yog tias lub roj teeb hluav taws xob tsis siab txaus rau lub cuab yeej thaum nws siv ncaj qha. Joule tub sab nyiag hluav taws xob ntsuas qhov hluav taws xob thiab tam sim no los ntawm lub roj teeb kom qhov hluav taws xob siab txaus, rau lub sijhawm, rau lub cuab yeej ua haujlwm tsis tu ncua.
Kauj Ruam 1: Yam Koj Xav Tau
Rau qhov kev qhia no koj yuav xav tau cov khoom hauv qab no. Transistor 2N3904: 1K Resistor: Ferrite toroid coreFew wiresLedA siv AA roj teeb (yog tias koj tsis muaj ib qho uas koj tuaj yeem siv AA tshiab ib yam nkaus)
Kauj Ruam 2: Ua Haujlwm Hauv Circuit Court
Joule Thief yog tus kheej-oscillating voltage booster. Nws yuav siv lub teeb liab qis tsis tu ncua thiab hloov nws mus rau hauv cov khoom siv hluav taws xob ntau zaus ntawm qhov siab dua. Nov yog qhov pib Joule Thief ua haujlwm li cas, ib qib zuj zus: 1. Thaum pib lub transistor tawm. 2. Ib qho hluav taws xob me me dhau los ntawm tus tiv thaiv thiab thawj kauj rau lub hauv paus ntawm transistor. Qhov no ib nrab qhib rau cov neeg sau-tso tawm channel. Tam sim no hluav taws xob tuaj yeem taug kev los ntawm cov kauj thib ob thiab los ntawm cov khoom siv-tso tawm channel ntawm transistor. 3. Kev nce nqi hluav taws xob los ntawm cov kauj thib ob ua rau muaj qhov sib nqus sib nqus uas ua rau muaj hluav taws xob ntau dua hauv cov kauj thawj. 4. Cov hluav taws xob induced nyob rau hauv thawj kauj mus rau hauv lub hauv paus ntawm transistor thiab qhib rau cov khoom siv-emitter channel ntau dua. Qhov no tso cai txawm tias muaj hluav taws xob ntau dhau los ntawm lub kauj thib ob thiab los ntawm cov khoom siv tso tawm ntawm cov transistor.5. Cov Kauj Ruam 3 thiab 4 rov ua dua nyob rau hauv cov lus tawm tswv yim kom txog thaum lub hauv paus ntawm transistor tau saturated thiab cov khoom siv-emitter channel tau qhib siab. Cov hluav taws xob taug kev los ntawm cov kauj thib ob thiab los ntawm cov transistor tam sim no yog qhov siab tshaj plaws. Muaj ntau lub zog tsim nyob hauv thaj chaw sib nqus ntawm lub kauj thib ob. 6. Txij li thaum hluav taws xob nyob rau hauv lub kauj thib ob tsis tau nce ntxiv, nws nres inducing hluav taws xob hauv thawj kauj. Qhov no ua rau hluav taws xob tsawg dua mus rau lub hauv paus ntawm transistor.7. Nrog tsawg dua hluav taws xob nkag mus rau lub hauv paus ntawm transistor, cov khoom siv-emitter channel pib kaw. Qhov no tso cai rau hluav taws xob tsawg dua los ntawm kev sib tw thib ob. 8. Kev poob qis ntawm cov nqi hluav taws xob hauv lub kauj thib ob ua rau muaj qhov tsis zoo ntawm cov hluav taws xob hauv thawj lub kauj. Qhov no ua rau muaj hluav taws xob tsawg dua mus rau lub hauv paus ntawm transistor.9. Kauj Ruam 7 thiab 8 rov ua dua nyob rau hauv cov lus tawm tswv yim kom txog thaum yuav luag tsis muaj hluav taws xob hla lub transistor.10. Ib feem ntawm lub zog uas tau khaws cia hauv thaj chaw sib nqus ntawm lub kauj thib ob tau ntws tawm. Txawm li cas los tseem tshuav ntau lub zog khaws cia. Lub zog no xav tau mus rau qhov chaw. Qhov no ua rau qhov hluav taws xob ntawm qhov tso tawm ntawm cov kauj mus rau qhov siab. 11. Kev tsim hluav taws xob tsis tuaj yeem hla lub transistor, yog li nws yuav tsum hla lub nra (feem ntau yog LED). Qhov hluav taws xob ntawm qhov tso tawm ntawm cov kauj tsim kom txog thaum nws mus txog qhov hluav taws xob qhov twg tuaj yeem hla mus rau qhov thauj khoom thiab yuav ploj mus. 12. Lub zog tsim los mus dhau ntawm lub nra hnyav. Thaum lub zog tau ploj mus, lub Circuit Court tau rov pib ua haujlwm tau zoo thiab pib tag nrho cov txheej txheem ib zaug ntxiv. Nyob rau hauv ib txwm Joule Thief Circuit txheej txheem no tshwm sim 50, 000 zaug hauv ib pliag.
Kauj Ruam 3: Npaj Toroidal
Kev hloov pauv hauv Circuit Court yog ua los ntawm cov xaim hlau nyob ib ncig ntawm ferrite toroid. Cov toroids no tuaj yeem yuav los ntawm cov khoom siv hluav taws xob lossis lawv tuaj yeem khaws tau los ntawm cov cuab yeej siv hluav taws xob qub xws li cov khoom siv hluav taws xob. Ua ob daim nyias nyias insulated xaim thiab qhwv lawv ib ncig ntawm lub qhov hluav taws xob 8-10 zaug. Ceev faj tsis txhob sib tshooj ntawm cov xov hlau. Ua kom cov xov hlau sib nrug sib nrug kom ntau li ntau tau. Txhawm rau tuav cov xov hlau nyob hauv qhov chaw thaum kuv tab tom tsim qauv, kuv qhwv lub toroid hauv kab xev thiab tom qab ntawd koom nrog ob txoj kab xim sib txawv ntawm ob qho kawg ua ke raws li qhia hauv duab & xa cov vis dis aus kom nkag siab zoo.
Kauj Ruam 4: Txuas Nws Txhua Qhov Ua Ke
ua raws li cov lus hais saum toj no thiab muab cov positvive ntawm tus coj coj los sau rau ntawm transistor & tsis zoo rau tus emitter & 1 k ohm rau lub hauv paus ces ib qho ntawm cov hlau ib leeg ntawm toroid rau tus sau & lwm yam rau 1k resistor raws li qhia hauv duab & yees duab thiab txuas cov xaim mus rau tus xa hluav taws xob tom qab ntawd txuas +ve ntawm lub roj teeb rau ob qho ua ke sib txuas xov tooj cua ntawm toroid & -v lub roj teeb mus rau xaim txuas nrog rau emitter.
Kauj Ruam 5: Xeem Nws
Tom qab siv nws tag nrho ua ke peb tuaj yeem rov pib dua peb lub roj teeb AA qub los ua lub zog LED thiab siv nws ua lub teeb taws me me uas siv los ntawm ib lub roj teeb AA thiab hauv txoj kev no peb tuaj yeem siv peb cov qub AA roj teeb.
