Infrared pen for the Wiimote Whiteboard

Manual for making an Infrared pen for the Wiimote Active schoolboard:

In this manual you can create an Infrared pointer which can be used in combination with the Wiimote

Whiteboard program of Johnny Chung Lee as shown on Youtube . The basis is formed by a standard

laser pointer of Velleman products which is changed into an Infrared pointer with a 5mm power IR LED,

for example P/N 276-143 which can be ordered at Radio Shack.
