Lub npe ntawm qhov project hais txhua yam. Nws yog lub cuab yeej uas yuav them yam khoom xws li Ipods, PDAs, lwm yam khoom siv uas ntsaws rau hauv USB kom them.

Kauj Ruam 1: Cov khoom siv

Cov ntu xav tau rau txoj haujlwm no yog txhua yam hauv daim duab thib ob.

Koj yuav xav tau: LM lossis MC 7805 +5VDC Voltage Regulator Hom-A Poj Niam USB Port 100 UF Electrolytic Capacitor 10-50v 0.1-0.5 UF Capacitor 6-50v (txhua yam yuav ua) 150-160 ohm Resistor (xaiv tau) 9V Roj teeb clip 2.2V 20mA LED xim uas koj xaiv (xaiv tau) Unprinted Circuit board ON/OFF Switch (yeem) Cov khoom no tuaj yeem yooj yim yuav ntawm koj lub khw hluav taws xob hauv nroog, zoo li Xov Tooj Cua. Lossis koj tuaj yeem yuav lawv online ntawm: https://www.digikey.com Tus Tswj: https://search.digikey.com/scripts/DkSearch/dksus.dll? Nthuav dav? Name = LM7805CT-ND USB chaw nres nkoj: http:/ /search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=151-1080-ND 100 uF Capacitor: https://search.digikey.com/scripts/DkSearch/dksus.dll? detail? name = P12392- ND 0.1 uF Capacitor: https://search.digikey.com/scripts/DkSearch/dksus.dll? Nthuav dav & lub npe = 399-4151-ND

Kauj Ruam 2: Lub Rooj Tsav Xwm Circuit (Txoj Kev Yooj Yim)

Cov duab hauv qab no qhia txog PCB npaj ua ntej muab cov khoom tsim nyog.

Dab tsi koj tab tom saib yog sab hauv qab ntawm PCB nrog cov ntawv ci tooj liab ntsib koj. Cov kab txho sawv cev rau qhov chaw uas yuav txiav. Nco ntsoov tias 3 ntu raug cais los ntawm hluav taws xob (tsis txhob ua rau ib leeg). Yog tias koj muaj cuab yeej dremel, koj tuaj yeem ntsuas tus tooj liab cladding nrog lub log txiav. Cov dots dub yog qhov chaw uas yuav tsum tau siv qhov drilled.

Kauj Ruam 3: Nqa cov Cheebtsam

Saib xyuas qhov sib txawv thaum muab tso rau hauv cov khoom, tshwj xeeb tshaj yog cov tswj hwm, lossis nws yuav kub heev thiab hlawv tawm.

*Ua ntej ntsaws koj lub cuab yeej USB rau lub charger no, sim ntsuas lub charger kom siv lub ntsuas ntsuas. Hookup lub 9-volt roj teeb thiab ntsuas qhov hluav taws xob tso tawm, nws yuav tsum nyob nruab nrab ntawm 4.8-volts rau 5.2 volts. *Yog tias lub teeb dub tuaj thaum koj ntsaws lub iPod rau lub charger, qhov ntawd txhais tau tias lub roj teeb ua haujlwm raug, thiab yog tias lub teeb dub tsis tuaj tom qab 3 vib nas this, tshem lub iPod tawm ntawm lub charger tam sim, thiab tshuaj xyuas koj lub charger rau luv los yog polarity tsis yog. *Yog tias koj ob zaug tshuaj xyuas qhov tso tawm thiab tseem tsis muaj hmoo, sim txuas nrog lub txhab nyiaj tiv thaiv kab mob piav qhia hauv cov lus hauv qab no rau kab ntawv.

Kauj Ruam 4: Luam Luam Circuit Board

Thawj daim duab yog lub voj voog uas yuav tsum tau muab ntxig rau hauv PCB, daim duab thib ob qhia qhov twg txhua yam yuav tsum mus.

*Koj saib rau sab nrog cov ntawv ci tooj liab, yog li saib qhov sib txawv thaum muab tso rau hauv cov khoom

Kauj Ruam 5: Luam Circuit Court nrog LED

Qhov kev tsim no suav nrog LED uas yuav tau taws thaum lub cuab yeej qhib.

Kauj Ruam 6: Ntxiv Qhov Hloov

Ntxiv qhov hloov mus rau hauv Circuit Court no yooj yim heev, nws yuav txuag roj teeb ntau thaum koj tua nws dua li tsuas yog tso nws tseg. Koj tuaj yeem txuas qhov hloov pauv nyob txhua qhov ua ntej lub capacitor (yog tias koj tsis tau siv lub capacitor, tom qab ntawd ua ntej 7805).

Kauj ruam 7: Ua tiav

Tam sim no koj tau ua tiav kev tsim koj tus kheej lub USB them nyiaj, txhua yam koj tau ua dhau los yog muab nws tso rau hauv lub thawv zoo thiab qhia tawm rau koj cov phooj ywg!
