meron na rin pong mga gadgets na ganyan, sa cdr king yata meron nyan, hand cranked na cellphone charger.

hindi pwedeng diretso yung motor sa battery, dapat may circuit ka in between to regulate the voltage at capacitor para maistore lahat ng power na nagenerate before doing the conversion.

COEJAYSON,

Sabi mo nga parang sa bike, yun, bumili ka ng "dynamo" ng bike. pwede yn dahil 6 V, and cellphonebatt 4.8V kaya lang maselan ang charging ng lithium ion. Solution is to buy a car cellphone charger. 12V nga lang, so you have to series 2 dynamos to get 12V or make your own dynamo. then put diodes para maging dc. stepper motor good candidate, mayroon ako pero P700 bili ko. ikutin mo sa bike but you to modify bracket and ulo where to spin. Better to series 2 bike dynamos.

maganda yung staqtionary bike pang exercise na may nakakabit na alternator, kahit na yung pang multi cabna medyo mallit. kaya lang need mo ang car battery dahil hinde PM. You can use wiper motor or aircon motor as generator.

generator is DC, alternator AC.

meron n kami circuit eh,,nid namin ung steeper motor na pwde magbgay ng 12 volts tapos gamitan namin ng 7806 para maging 5v ung output nia? para pwde n kami magcharge ng batery...prob namin ung application kung panu ikutin...may gumawa na ng windmill at ng turbine ...kami ay manual ung gnun nga po sa bike na stationary ...so if wala po kami mhanap na stepper motor,,,ung sa bike nalang po pala...tnx

Oo.pwede yon. kung 6V, isa lang. kung 12V , dalawa in series. The cheap china charger is good and has contrl for overcharging. anyway, if you have the circuit already...ok. I ave a simple circuit din that will not ruin the cp...if you need it.. I can sell you a stepper pero, yung nga, you have to built the holder to the bike. Yung ulo mukhang pwede na ito dahil may pulley for a flat belt na ma engage na rin sa tire ng bike. Text ka lang...in case.
