Joule Thief - Siv LEDs Tsuas Muaj Ib Lub Roj Roj AA!

Ua cov khoom siv LED nqa tau tuaj yeem ua rau me ntsis vim yog lub roj teeb. Joule Thief daws qhov ntawd, los ntawm kev txhawb nqa ib leeg AA roj teeb qhov hluav taws xob mus rau qib siab txaus kom pom lub teeb. Lawv raug nqi $ 7 txhua qhov. Qhov khoom siv los ntawm thejoulethief yog qhov nthuav hauv qhov tseeb tias nws sib txawv los ntawm tus qauv loj loj joule tub sab tsim rau me me thiab compact pcb teeb tsa nrog ob peb yam ntxiv rau kev ua haujlwm.

Kuv xub xaiv muab tso rau hauv inductor. Tus inductor zoo li cov rog rog. Muaj ib qho chaw ntawm PCB daim ntawv lo "L1" qhov twg tus inductor yuav tsum mus. Ntxig lub inductor, khoov cov coj kom nws hais tias muab tso, thiab muab nws tso rau hauv.

Lub sijhawm rau cov neeg tawm tsam. R1 yog 2.2k resistor (liab liab liab). R2 thiab R3 yog 1k resistors (xim av dub xim liab) Nco ntsoov tias koj yuav tsum teeb lub resistors ntsug kom txuag chaw.

Cov kauj ruam tom ntej yog yam nyuaj. Cov transistor coj yog ib txwm nyob hauv kab, txawm li cas los txhawm rau lawv hauv PCB koj yuav tsum tau khoov cov coj mus rau hauv daim duab peb sab (saib daim duab). Tom qab khoov cov hlau lead, ua tib zoo thawb lub transistor mus rau hauv pcb kom txog thaum nws zoo. Solder.

Qhov lom zem! Muab cov LED tso rau hauv, xyuas kom tseeb tias koj nco ntsoov kev taw qhia. Qhov chaw tiaj tus ntawm LED mus rau qhov chaw tiaj tus ntawm silkscreen.

Silkscreen cov cim uas xaim zoo thiab tsis zoo. Muab qhov ua tau zoo coj mus rau ib lub roj teeb AA, tuag lossis tshiab, thiab pom lub teeb ci LED! Lub voj voog ua haujlwm tawm ntawm "tuag" AA roj teeb, ua rau nws yog txoj hauv kev zoo rau rov siv koj li qub AAs. Mus nqa ib pob khoom ntawm www.thejoulethief.com thiab muaj kev lom zem!
