Hi all, I am building this cct to reduce the vibration in a 2.4Ghz radio controlled helicopter. I will be using a vibration motor instead of a basic one. I have a couple of questions I hope you guys could help with. 1. What vibration motor would be the best to use to achieve my aim and 2. The breadboard I am using is quite small, is there a min/max voltage/current to certain sized breadboard? Thank you in advance for any expert input.
