Set the pen on a flat surface such as a workbench and get its measurement. Divide the circuit board piece into three pieces of the same size as the pen. Apply cyanoacrylate liberally to the bottom side of each piece and place the glue side against one face of the pen. Lastly, bend the last two circuit board pieces towards each other to meet the remaining face of the pen. For more information, visit http://www.ehow.com/how_12100411_make-circuit-board-pen.html.
