making a light pen

Today in class, I finally finished my second light pen, but I had a little problem of my momentary switch. It kept poping out of the hole, so I'm thinking to super glue it later. After finishing my pen, I helped Jaime to finish his. He massed it up, so it was hard to fix it. At the end of the class, I almost finished Jaime's pen. I got use to the wires now, and it's pretty fun to make a light pen now. I can't wait untill I get to use the multi-touch whiteboard.
