Hi,

If you are using a pen made by your own, make sure you are using a high-powered IR LED with the correct wavelength. Most probably your IR LED is not suitable for the Wiimote where the power emitted is low or the bandpass filter of the Wiimote has filtered most of the power going through the filter.

For convenience, please do use the Vishay TSAL 6400 as many have tested it before.

Other common issues that may cause discontinued drawings are such as non-genuine Wiimote, low tracking utilization (Wiimote too far from the screen), and insufficient battery for the IR pen.

You can find more information by referring to the positioning of the Wiimote from

In the Smoothboard User Guide (http://www.smoothboard.net/files/doc/Smoothboard_User_Guide.pdf), we have included the causes and also the potential solutions for the tracking issues. This can be found in the last chapter, 7.9 page 65.
