Lub teeb nyem no siv tsuas yog 1 lub roj teeb AA loj los ua kom muaj zog 2X 5mm LEDs dawb (lub teeb pom kev tawm). Lub roj teeb 1.5V tsis muaj qhov hluav taws xob txaus txaus los txhawb cov LEDs. Peb xav tau lub Circuit Court los txhawb qhov hluav taws xob nkag mus rau qhov hluav taws xob rau pem hauv ntej ntawm LEDs kom pom lawv. Qhov Circuit Court hauv qhov no yog qhov thaiv oscillator (aka joule thief) Circuit topology. Nws tau hu ua joule tub sab vim tias nws muaj peev xwm ua kom pom cov LEDs nrog siv roj teeb kom txog thaum nws ua haujlwm tiaj tus.

Kuv tau ua qhov kev sib tw tub sab tub nyiag me me siv lub hauv paus me hauv cov vis dis aus saum toj no.

Kauj Ruam 1: Sau cov cuab yeej xav tau thiab cov khoom siv

Cov cuab yeej xav tau:

1. Soldering hlau
2. Solder
3. Pliers rau kev txiav cov khoom siv ua
4. Penknife
5. Kub nplaum phom nrog kua nplaum
6. Breadboard (yeem)

Yuav tsum muaj cov khoom siv:

1. 1Ω resistor, 1/4W (1pc)
2. Txuas cov xov hlau (cov tub ntxhais khov)
3. 18650 Li-ion cell holder rau 2 18650 cells (1pc)
4. AA roj teeb yas dhos (1pc)
5. 2N2222 lossis 2N4401 lossis 2N3094 NPN transistor.
6. Npaj ua lub tshuab hloov pauv nrog 2 txheej ntawm cov hlua, lossis khaws cia me me hom hom hnoos qeev, lossis koj tuaj yeem ua koj tus kheej hloov pauv.

Kauj Ruam 2: Ua Koj Tus Kheej Transformer

Kuv tau pom qhov tsim hluav taws xob tsim nyog rau kuv qhov haujlwm, tab sis kuv yuav qhia koj yuav ua li cas hloov lub tsev hloov pauv.

Rau kev hloov pauv hauv tsev, koj yuav xav tau

1. Ib qho me me toroidal core uas koj tuaj yeem pom los ntawm CFL tawg
2. qee cov xaim tooj liab xaim uas koj tuaj yeem khaws tau los ntawm ib qho khoom siv hluav taws xob uas muaj ferrite core transformer. Lossis koj tuaj yeem yuav koj tus kheej xwb.
3. Koj yuav xav khaws lub mini ferrite core transformer los ntawm lub xov tooj ntawm tes thiab siv nws los ua koj tus kheej inductor.

Sib sau 2 txoj hlua tooj liab xaim xaim thiab cua 12 tig ntawm cov xov hlau nyob ib puag ncig lub hauv paus toroid raws li qhia. Koj yuav tsum tau txais 1: 1 piv ntawm koj lub tshuab hloov pauv. Nco ntsoov kom tsis txhob sib tshooj cov xov hlau thaum winding. Kuv siv ø0. 5mm enameled tooj liab xov hlau. Koj tuaj yeem sim cov naj npawb ntawm qhov tig thiab ntsuas cua xaim kom tau txais txiaj ntsig zoo tshaj plaws

Kauj Ruam 3: Soldering Cheebtsam

Xa mus rau cov txheej txheem raws li tau qhia thiab Cov khoom siv Solder ntawm ib pawg thawj coj. Koj yuav xav tau txiav lub rooj tsavxwm kom me me nrog hacksaw kom haum rau hauv rooj plaub. Luag tag nrho cov khoom ua ntej.

Kauj Ruam 4: Tua Txhua Qhov Kev Sib Txuas

Siv cov tub ntxhais hlau xaim txhawm rau txhawm rau txuas txhua qhov kev sib txuas. Tshem tawm rwb thaiv tsev yog tias muaj, koj yuav tsis xav tau lawv.

Kauj ruam 5: Xeem

Ua ntej muab txhua yam tso rau hauv rooj plaub, sim koj cov khoom siv hluav taws xob los ntawm kev siv lub roj teeb tuav rau hauv Circuit Court uas koj nyuam qhuav tau tsim yav dhau los.

Kauj Ruam 6: Txiav tawm ntawm Koj Cov Ntaub Ntawv

Kuv tau siv rooj plaub uas haum rau 2X Li-ion 18650 hlwb. Txiav tawm ib qho kab tav twg uas cuam tshuam qhov kev tso koj li hluav taws xob thiab lub roj teeb. Txiav tawm qhov rau LEDs. Muab koj lub rooj sib dhos sib dhos thiab lub roj teeb tso rau hauv rooj plaub kom pom nws zoo li cas, tsis txhob ua kua nplaum rau lawv. Txiav txim siab tawm qee qhov chaw rau koj qhov kev hloov pauv (Kuv siv lub mini swb hloov hauv qhov no). Tom qab ntawd txiav tawm rau koj qhov kev hloov pauv ntawm qhov chaw xav tau.

Kauj Ruam 7: Muab Txhua Yam Ua Ke

Siv qhov hloov pauv ntxiv hauv koob rau hauv Circuit Court. Kuaj xyuas seb qhov hloov pauv puas ua haujlwm. AA lub roj teeb loj ntawm 0.5V - 1.5V yuav tsum ua kom pom cov LEDs. Tom qab ntawd txuas mus rau lo txhua yam. Qhov ntawd yog nws, koj tau ua koj tus kheej lub teeb 1.5V. Ua tsaug rau kev nyeem kuv cov lus qhia thiab tsis txhob hnov qab pov npav.
