Hi folks!

I want to introduce my IR Pen. It's made from a usual ballpen. But I'm afraid, I forgott to take a photo of the pen before the modification.

I faced the problem that when the pen was in a too sharp angle the Wiimote was not possible to track the IR-Light anymore.
I used an TSAL6200 LED which has a only 17° "lightcone". That's pretty less I think. So I thought how I can increase the beam of light. So I came up with a usual aluminium foil.

What do you think of this solution?
