Sorry to post twice in one day.  I am just in love with the potential for this project.  I'm just wondering if most people have a problem with jagged lines...ie, in paint I can not draw a circle.  Not sure if it is my pen, me, or if anyone else was encountering the same issues.  Thank you again for the previous comments. 

Just thought of another question on the way home from work.  Are there any legal issues with using this?  I know that the software is free and open source but I was unsure of the wiimote use since it is being used for something other than it was designed for.

From what I understand that is from the wii remote only handling 1024x768, if your screen resolution is higher than that, it will seem "jumpy", also the positioning of your wii remote is a factor in that. I seem to have the same problem though :).

Legal issues? I am no lawyer so take this as you will... Nintendo is selling the remotes for use, is there a way that they can tell us how we can use it? We are not breaking encryption or stealing something, but simply hooking it up via the built in bluetooth... I think if they were worried about this kind of thing, they would have made the remotes use something other than bluetooth. That is just my personal opinion.

the resolution doesnt have nothing to do with your screens resolution, it can can take foto's of 1024x768, so it sees your whole screen.

I've had a similar problem with non-straight lines, and I noticed that when I changed the batteries it got a lot better. 

This tells me that the brightness of the light is a big factor.  How do I make a brighter IR pen?

Or am I way off on drawing that conclusion?

I have also been looking for a brighter IR LED.  The only one that I have been able to find is at photonlight.com which I have seen the link for a couple of times throughout other people's posts.  I might have to suck it up and buy one to see if it makes a difference.  I will reply again if I get one this week.

for my own experience, I think is not a reflection problem. I suppose that it's a positionning or environnemental  problem. I explain :
I have make my own ir pen, and my white board works perfectly.

few months later, a friend tell me that when he's drawing, the line is not continuous, but made with dots.
I try again now with my "working" pen And I have the same problem !!!

so, it's not due to power reflection of my pen because it's working well in the past.

I need to try few things :
- wiimote positionning,
- environnement lights and reflective surface
- test with differents wiimote (perhaps software updates cause problem)
 I don't kown exactly, but the IR power is not, I think, the real problem.

I will investigate in few days. If someone have more information tell us !

What IR-Led are you using and what power source.

Maybe also change your batteries.

As for legal none, its just like using a Mac mouse on a microsoft PC.
