Project Overview

In order to recycle discarded PCs in a creative way, I decided to design and create the pen plotter. The X and Y axis stepper motors came from the DVD drives in the CPU and I found the plexi-glass surface from a previously used fixture. Each stepper motor is controlled via an L293D IC and the servo motor is connected directly to the µController's GPIO.

Key Learnings

• Creating custom PCBs using Eagle CAD
• Arduino C++ and Processing GUI for Arduino
• Designing mechanical parts in SolidWorks and error of margin
