The following are the list of of supplies that I have ordered to build the electronic portion of the device.
Arduino Rev 3 Starter Kit : The Arduino Uno Board was already supplied in lab but I am required to purchase one for another class I am currently taking so I decided to buy this kit so I also have the bread board, holder, and wires for use in this project.
Futaba S3003 Servo Standard (2): After investigating several different models of servo motors I settled on this one based on reviews and torque provided.
Microtivity Push-and-Lock Button Switch: I am purchasing with the desire for an on/off switch in mind but also with further development for different shaking intervals.
Wall Adapter Power Supply 9VDC 650 mA: I thought about using a battery adapter but decided on the wall adapter because of not wanting to purchase large quantities of batteries if this proves to be of practical use for my job.
I am still not sure if I am going to need an additional power supply for the servo motors or if I am going to be able to simply draw the power from the board.
