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.
Kauj ruam 1: Qhib Qhov Chaw
Txuas nrog yog Eagle schematic thiab board cov ntaub ntawv.
Kauj Ruam 2: Sau Qhov Chaw
Xyuas kom koj muaj tag nrho cov ntu. Nov yog cov npe: PCB Qty 2. Transistor2.2k resistorQty 2. 1k resistorInductorCapacitorLED (koj xaiv xim) Qty 2. cov xov hlau
Kauj ruam 3: Inductor
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.
Kauj ruam 4: Resistors
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.
Kauj ruam 5: Capacitor
Lob lub capacitor, ntxig rau hauv qhov chaw sau lo lus C1, khoov thiab muab tshuaj txhuam.
Kauj Ruam 6: Transistors
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.
Kauj Ruam 7: LED
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.
Kauj Ruam 8: Hlau
Nov yog qib kawg. Saj cov xaim xaus, thiab muab nws tso rau hauv cov pawm ntawm PCB. DONE! Tom ntej no nws yog lub sijhawm los sim nws!
Kauj Ruam 9: Xeem
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!
