Even when mounted by suspension from rubber straps and sitting in my basement, the vibration can be felt at the other end of the house. For a very small amount of power, you can achieve extremely strong vibration. Go with the motor! | |

| Jul 10, 2013 at 14:37 | comment | added | enterprize | yes,life time of a solenoid is a concern as it gets warm very quickly.Offset motor actually will suit more for my work as I mentioned in OP,I will expand this reading by walking stick to reading by mobile too.& this will help me.Can you please suggest some offset motor that is powerful enough to generate vibrations that are sensed by a walking stick i.e. a white cane or some guideline for that.If I get an off the shelf solution it will help. | |

You could make one yourself from your choice of motor. A solenoid will not last long under repeated vibration. | |

Solenoid appears to be choice as these offset weight motor appear generating very weak vibration for it to be sensed through a walking stick & vibration patterns to be recognized. | |
