Quite a long title.

Here is my first attempt at making a linear vibration feeder using (you guessed it) a simple vibration motor.

There are 2 main components to this feeder method. The spring arms, angled at 15-30 degrees, and the vibration motor. The angle insures that any movement right is always accompanied with a movement up (increasing friction) and left is always going down (decreasing friction). The vibration motor is mounted to the top and provides the force to sway the springs left and right. A track is mounted to the top of the spring.

I do want to experiment with a feeder using an electromagnet, but for now, this has worked surprisingly well.
