hi i bought this motor at jalan pasar...

http://nexttronics.amazonwebstore.com/Sony.../B001DH728C.htm

but there is no info about RPM and torque. its a audio system motor. this kind of motor can never be powerful enough to power RC cars right?

hi i am completely new to Electronics i need to create a motor circuit that will have a 10 sec delay before the motor starts running when the circuit is close.

i tried to do some google on this and it says a 555 IC and RC circuit will do the job , some says 555 is not needed. but im totally new and i dun understand the sample circuit.

is it really as easy as putting a resistor and capacitor on a series circuit ? using the formula T = R * C to calculate the time delay?

If the answer is no , may someone please show me how it is done. thanks a lot

It just call timer. Come with sec, min and hr. Need to specific voltage for the coil.

i went to the shop today...it cost rm 50 - rm 63...

damn expensive. i wonder does it worth? if a simple lm555 with few capacitor and timer can do the job..
