Yes, the subject sounds stupid but the question is even stupider! ever since I was a kid I've liked building things, especially with electronics but I've never had any real education towards it etc etc no skills blah blah. Right now I want to build an IR pen for a project that was posted a while ago on the forum. The idea is to make a pen like: http://johnnylee.net/projects/wii/pen.jpg The problem is every momentary switch I see online, like http://www.sparkfun.com/commerce/product_info.php?products_id=8720" that is actually low-profile enough is build like a square, for lack of better terminology. The button is suppose to be in the pen so that you can press the button easily as if you were going to write with the pen. The button is square, the pen is hollow and round. How do you put this together? Also, the LED is smaller then the open end of the pen casing so I need to figure out how to make it fit more snug... Where do I learn to make crazy cool gadgets!? I need some sort of ... metal... that's like playdough but its metal!
