Hi everyone. So I have this idea to build a card holder that will vibrate (like a phone) when a card slip out of place. In order to do that, i need a a small vibration motor! I end up extract one from the old nokia phone but it's doesn't work when connect to DC supply. Does it need a oscillating voltage supply to work? How to achieve maximum vibration? Is there any places i can get similar thing?
