How to put a delay timer on a micro motor small Area

Question

I am trying to put a micro motor basically as small as I can inside of a 1"or so wide tube like a long fishing plug, I am going to put a small prop or propeller on one end. What I need is to be able to have that motor to run that prop maybe run on a 3v battery, I need the motor to run on a delay to kick on run the prop for 1 or 2 seconds shut off then in about 3 seconds kick on and continue do the same thing, any suggestions on what I would have to do to make a motor do that cheaply Don

Answer 1

A 555 timer in an astable configuration should do the trick. You can't get a shorter on period than the off period, so you'll need to use some kind of signal inverting element. Here i'm using an N-type mosfet to control the motor.
