Hi Allison. I was wondering if you and your students would be interested in participating in a nationwide SAT Vocab Video Contest @ MIT university. If not, perhaps you have some educator contacts you could direct me to. You can view contest details at BrainyFlix.com Please let me know. Thanks!
Hi Allison, There's a great forum where users are creating these pens and posting their results. It's at http://www.wiimoteproject.com/ir-pens/. Some have found that it's easiest to find a pen that already has a white led light and to remove the light and resolder an IR led onto it. Others build the whole thing from scratch. If I was doing it again I would buy a premade pen and swap the LED because the housing can be an issue if you use a battery pack.
