Prototyping: Donation Box Rotating Lid Assembly

Rotating donation lid / top view from iamnotarobot on Vimeo.

The donation lid will sit on the top of the donation box and rotate to open and close the donation slot. I'm now testing stepper motors instead of servos. Steppers allow for controlled movement but they can't store position data like a servo motor. If someone disrupts the movement of the lid the motor will stall and there is no easy way to "reset" the position of the motor.
