Wiimote Whiteboard IR Pen

Step 2 Prepare the Highlighter

We need to do two things: remove the internal guts of the highlighter and create a hole for the momentary switch. The easiest way to remove the internals of the pen is to use a pair of pliers (I used my leatherman) to pull the bottom end cap off of the pen. The internal highlighter part can then be removed.

To make a hole for the switch I used a cheap soldering iron to melt a circle into the side of the pen slightly smaller then the switch. Then, before the plastic had cooled, I pushed the switch into the hole ensuring the switch fit snuggle and eliminating the need to glue or otherwise attach the switch later.
