Arduino Controlled 3 Axis Pen Plotter

This is my 3-axis pen plotter that is controlled using an Arduino. The stepper motors were removed from three CD-ROMS. each stepper motor is connected to a SN755410NE H-Bridges. The H-bridges get signals from the arduino which then control each stepper motor. It was my goal to make this as cheaply as I could & it ended up costing me $30 since I already own many arduinos. With the included cost of the Arduino it would cost $60.
